Description

Interface display method and related device

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office with the application number 201911425231.6 and the application name "Interface Display Method and Related Devices" on December 31, 2019, the entire content of which is incorporated into this application by reference.

Technical field

This application relates to the field of terminal technology, and in particular to an interface display method and related devices.

Background technique

Compared with the traditional screen, the foldable display screen has the characteristics of strong flexibility and foldability. For the folding screen device, because it is equipped with a foldable display screen, the display screen of the folding screen device can be switched between a folded form and an unfolded form.

When the display screen is in a folded form, the folding screen device can switch between the two display areas of the display screen according to the posture of the folding screen device. For example, the two display areas may include a first display area and a second display area. As shown in Figures 1a to 1b, the folding screen device can detect that the gesture of the folding screen device is switched from the first display area facing the human face to the second display area facing the human face, and the folding screen device can display on the first display area The content is switched to the second display area for display.

Please refer to FIGS. 2a to 2c, which are schematic structural diagrams of a foldable display screen in an electronic device provided by an embodiment of the present application. The foldable display screen is applied to electronic equipment.

(1) Opening angle

As shown in FIG. 2a, the foldable display screen may include a first display area and a second display area. The first display area and the second display area are connected by a bending part. The display screen can fold the first display area and the second display area in half through the bending part. In an implementation manner, the bending part may belong to a part of the display screen and may be used for display. The bending part, the first display area and the second display area are integrated. In another implementation manner, the bending part may only be used to connect the first display area and the second display area, and the bending part may not belong to a part of the display screen.

In the embodiment of the present application, the foldable display screen may include at least the following forms: a flattened form, a folded form, and an expanded form. The foldable display screen shown in FIG. 2a is in a flattened form, and the foldable display screen shown in FIG. 2b is in a folded form. The foldable display screen shown in Figure 2c is in an unfolded form. As shown in Figure 2b and Figure 2c, taking the folded form as a reference state, the angle at which the plane where the first display area is located and the plane where the second display area is located is rotated about the bending part as the axis can be called the opening of the foldable display screen. angle. In the embodiment of the present application, the opening angle of the foldable display screen may be between 0° and 180°, and may also be between 0° and 360°.

(2) Flat form, folded form and unfolded form

As shown in Figure 2a, in the flattened form, the angle between the plane where the first display area is located and the plane where the second display area is located, also known as: the opening angle of the foldable display screen is 180°±β. That is, the first display area and the second display area are in the same plane, and the first display area and the second display area are distributed evenly. The first display area and the second display area form a continuous display area through the bending part. The electronic device may display the user interface in the display area composed of the first display area and the second display area. In this state, the electronic device can display the user interface in full screen. Among them, β is a non-negative angle value, for example, 2°, 0°.

As shown in Figure 2b, in the folded form, the angle between the plane where the first display area is located and the plane where the second display area is located, also known as: the opening angle of the foldable display screen can be 0°+γ, for example The opening angle is 0°. Among them, γ is a non-negative angle value, for example, 3°, 0°.

As shown in FIG. 2c, in the expanded state, the angle between the plane where the first display area is located and the plane where the second display area is located is also called: the opening angle of the foldable display screen is α. The opening angle is the angle at which the plane on which the first display area is located and the plane on which the second display area is located in the folded state shown in FIG. 2b as a reference state are rotated with the bending part as the axis. Exemplarily, the value range of the opening angle α may include γ<α<180°, for example, the opening angle α in the folded state may include 30°, 45°, 90°, 150°, and so on.

It is understandable that the embodiment of the present application takes the left and right folding of the electronic device as an example for introduction, but it is not limited to the left and right folding. The electronic device may also be a device that is folded up and down, which is not limited in the embodiment of the present application.

The following describes the application scenarios involved in the embodiments of the present application. When the display screen is in a folded form or an expanded form, the folding screen device may only display the user interface on one of the first display area and the second display area. Specifically, when the display screen shown in Figure 2b is in a folded form and the display screen shown in Figure 2c is in an expanded form, the folding screen device can only display the user on one of the first display area and the second display area. interface. The exemplary folding screen device only displays the user interface in the first display area, and the second display area may not display the screen off. The folding screen device can select a display area from the first display area and the second display area to display the user interface according to the posture of the folding screen device. Among them, the posture of the folding screen device may include a change in the orientation of the display area. For example: the orientation of the first or second display area (for example, facing up or down), the first display area faces the human face, the second display area faces the human face, and so on.

When the display screen is in the folded form, the folding screen device is also in the folded form accordingly.

When the display screen is in the unfolded form, the folding screen device is also in the unfolded form accordingly.

When the display screen is in a flattened form, the folding screen device is also in a flattened form accordingly.

The folding screen device can determine whether the first display area faces the human face or the second display area faces the human face according to the corner, and select the display area facing the human face from the first display area and the second display area to display the user interface. In the embodiment of the present application, the specific principle of measuring the posture of the folding screen device through the gyroscope sensor can refer to the description of Figs. 13a to 13b, which will not be repeated here.

(2) Use the state of the display area to be held to determine the posture of the folding screen device

Generally, the display area facing away from the human face is continuously touched due to the holding habit. Therefore, a pressure sensor and/or a touch sensor can also be used to detect the state in which the first display area and the second display area are touched. The display area that is continuously touched can be recognized as the display area facing away from the face, so that the folding screen device determines the display area facing the face from the first display area and the second display area, and displays the user interface through the display area facing the face . For the specific principle of measuring the posture of the folding screen device using the state of the display area being held, reference may be made to the description of the pressure sensor in FIG. 11, which will not be repeated here.

(3) Use the face image collected by the camera to determine the posture of the folding screen device

In another possible implementation, a camera may be installed on the body where the first display area is located and the body where the second display area is located. Both the camera corresponding to the first display area and the camera corresponding to the first display area can capture images. The collected face image indicates that the corresponding display area faces the face. The folding screen device selects the display area facing the human face to display the user interface. For example, when the camera corresponding to the first display area collects a human face image, and the image collected by the second display area does not include a human face image, the folding screen device determines that the first display area faces the human face.

In the embodiment of the present application, the folding screen device may determine the posture of the folding screen device according to any one or more of the aforementioned methods, and select the display area facing the human face to display the user interface according to the posture. The folding screen device can detect its own posture in real time, and switch the display area for displaying the user interface according to the posture. For example, in the folded form, the posture of the folding screen device is that the first display area faces the human face, and the folding screen device displays the user interface in the first display area and closes the second display area. When the posture of the folding screen device changes, for example, from the first display area facing the face to the second display area facing the face, the folding device closes the first display area, opens the second display area and displays the user interface on the second display area. This function can be called the function of automatically switching the display area, that is, the first display content displayed in the first display area is switched to the second display area. When the first display content is switched to the second display area, the second display area can be displayed. The first display content is displayed simultaneously with the first display area; or after the first display content is switched to the second display area for display, the first display area is turned off.

In the embodiment of the present application, when the folding screen device detects a change in the display area facing the human face, that is, when the posture of the folding screen device changes, the folding screen device determines that the deflection angle of the folding screen device is greater than the deflection angle threshold. For example, if the folding screen device detects the switch from the first display area facing the human face to the second display area facing the human face through the sensor, it detects that the deflection angle of the folding screen device is greater than the deflection angle threshold, that is, the first display area faces the human face. Flip so that the second display area faces the human face.

Exemplarily, please refer to FIG. 1a and FIG. 1b. FIG. 1a and FIG. 1b are functional schematic diagrams of automatically switching the display area provided by an embodiment of the present application. As shown in Figure 1a, when it is detected that the posture of the folding screen device is that the first display area faces the human face, the folding screen device only displays the user interface 90 (for example, the main screen interface 90) in the first display area, and the second display area Can be turned off without displaying. As shown in Figure 1b, when it is detected that the posture of the folding screen device is flipped from the first display area facing up and the second display area facing down to the first display area facing down and the second display area facing up, the folding screen device can turn The user interface 90 displayed on the first display area is switched to the second display area for display. The folding device can close the first display area, open the second display area, and display the user interface 90 in the second display area. In this way, the convenience of display can be improved.

In the embodiment of the present application, detecting by the sensor that the first display area faces the human face includes the first display area facing upward, and detecting that the second display area faces the human face includes the first display area facing downward (the second display area faces upward). When it is detected that the first display area is facing the human face and the second display area is facing the human face, the folding screen device determines that the deflection angle of the folding screen device is greater than the deflection angle threshold, and turns from the first display area facing the human face to the second display area Facing the human face. In the embodiment of the present application, the flip is not limited to flipping the first display area upwards to the first display area facing downwards, but also includes flipping the first display area to the left to the first display area to the right. The embodiment of the present application does not do this. limited.

However, in a scenario where a folding screen device displays a QR code for scanning, for example, when a QR code interface is displayed in the first display area, because the user turns the device, the first display area faces the user’s face so that another device can scan the QR code. , And the folding screen device will switch the QR code interface to the second display area for display. Please refer to FIG. 3a and FIG. 3b. FIG. 3a and FIG. 3b are schematic diagrams of a scene in which a folding screen device provided in an embodiment of the present application displays a two-dimensional code for scanning. As shown in Fig. 3a, the folding screen device displays a two-dimensional code interface 10. When the user turns over the device so that the first display area faces the user’s face for another device to scan the QR code, as shown in Figure 3b, since the deflection angle of the folding screen device is detected to be greater than the deflection angle threshold, the folding screen device will The dimension code interface 10 is switched to the second display area for display. In this way, the two-dimensional code is always displayed through the display area facing the user, which is not conducive for the folding screen device to display the two-dimensional code to another device (such as a code scanner), which reduces the convenience of scanning the two-dimensional code.

In the display method provided by the embodiments of the present application, the display screen is in a folded or unfolded form. When it is detected that the folding screen device is switched to a specific user interface, such as a QR code interface, a picture interface, or a video interface, the folding screen device can close the above The function of automatically switching the display area. That is, regardless of the posture of the folding screen device, and regardless of the state in which the first display area and the second display area are touched, the folding screen device does not switch the display area for displaying the specific user interface. For example, when the folding screen device displays the two-dimensional code interface, only the two-dimensional code interface is displayed on the first display area, and the two-dimensional code interface does not switch to a different display area for display with the flip of the folding screen device.

For example, when the foldable screen device displays the QR code interface on the first display area, the foldable screen device turns off the function of automatically switching the display area, that is, when the user turns the device so that the first display area faces the user's face for another When the device scans the QR code, the folding screen device still displays the QR code interface on the first display area.

In the above two-dimensional code display method, the folding screen device detects that it is switched to the two-dimensional code interface, and then the function of automatically switching the display area is turned off. In this way, it is convenient for the user to turn the folding screen device so that another device scans the two-dimensional code, which improves the convenience.

In another possible implementation manner, when switching to the two-dimensional code interface, the folding screen device may display the two-dimensional code interface on both the first display area and the second display area. No matter how the user flips the folding screen device or changes the holding state of the folding screen device, the first display area and the second display area of the folding screen device both display the QR code interface for another device to scan the QR code, which improves Convenience.

In some other embodiments of the present application, the function of automatically switching the display area is turned off according to the specific user interface to which the display screen is in the folded state. The embodiments of the present application are not limited to being applied to a folding screen device including a foldable display screen. It is understandable that this application uses a folding screen device as an example for introduction, but it is not limited to a folding screen device, and may also be a multi-screen device with a display screen on both sides of the device, which is not limited in the embodiment of the application.

The user interface provided by the embodiment of the present application is described below. The user interfaces involved in the embodiments of the present application are all user interfaces of the display screen of the folding screen device in the folded or unfolded form.

In the embodiment of this application, the QR code interface 10 on the folding screen device may be a QR code payment interface provided by each application, such as the payment and receipt QR code interface of the WeChat application and Alipay application, and for example, the second payment interface of the Huawei Wallet application. Dimension code payment interface. Another device can scan the QR code payment interface, so that account transactions can be performed between the device and the account logged in by the application on the folding screen device. The other device may be a desktop or mobile code scanner device, or an electronic device such as a smart phone or a tablet computer. When switching to the two-dimensional code interface 10, the folding screen device can turn off the above-mentioned function of automatically switching the display area. That is, regardless of the posture of the folding screen device, the folding screen device does not switch the display area for displaying the specific user interface. For example, when switching to the QR code interface 10, if it is currently displayed on the first display area, the folding screen device will be fixed on the first display area to display the QR code interface 10, and the second display area will be closed without switching to The second display area is displayed. In another possible embodiment of the present application, when switching to the two-dimensional code interface 10, the folding screen device may display the two-dimensional code interface 10 in both the first display area and the second display area.

In the embodiment of the present application, the two-dimensional code interface 10 is introduced by taking the two-dimensional code payment interface in the WeChat application as an example. The following describes the QR code payment interface in the WeChat application involved in the embodiment of the present application. Please refer to Figs. 4a to 4h. Figs. 4a to 4h are schematic diagrams of some user interfaces provided by embodiments of the present application.

As shown in FIG. 4a, when the foldable display screen of the folding screen device is in a folded configuration, the display screen includes a first display area and a second display area. The first display area may display the user interface 20, and the user interface 20 may be a user interface of a WeChat application. The second display area can be turned off without displaying. Application 1 in FIG. 1a may be an icon 206 of a WeChat application. In response to a touch operation acting on the WeChat icon 206 on the main screen interface shown in FIG. 1a, the folding screen device can display the user interface 20. When displaying the user interface 20, the folding screen device may select one display area from the first display area and the second display area to display the user interface 20 according to the posture of the folding screen device. For example, when the first display area faces a human face, the user interface 20 is displayed in the first display area, and the second display area is closed. When the posture of the folding screen device changes (for example, the folding screen device is turned from the first display area facing the human face to the second display area facing the human face), the folding screen device can change the display area for displaying the user interface 20, and set the first display area to face the human face. The display area is closed, the second display area is turned on, and the user interface 20 is displayed in the second display area.

As shown in FIG. 4a, the user interface 20 may include: menu controls ("WeChat" 201, "Contacts" 202, "Discover" 203, "Me" 204), and a content display area 205. The content displayed in the content display area corresponding to different menu controls is different. The currently selected menu control shown in FIG. 4a is "WeChat" 201. That is, the content displayed in the content display area 205 is the content under the "WeChat" 201 menu. among them:

The content display area 205 includes a contact list 2051 and an add control 2052. The contact list 2051 includes multiple contacts, and is used for message interaction, voice paging, etc., with the multiple contacts.

In response to a user operation acting on the add control 2052, such as a touch operation, the folding screen device displays a selection box 2053. The selection box 2053 may include a group chat option 2053a, an add friend option 2053b, a scan option 2053c, a payment option 2053d, and a help and feedback option 2053e.

Among them, the initiating group chat option 2053a is used to initiate a group chat to multiple contacts. The add friend option 2053b is used to add a new contact. The scan option 2053c is used to enable the function of scanning the QR code. Help and feedback option 2053e, used to feedback user opinions.

In response to a user operation acting on the payment option 2053d, such as a touch operation, the foldable screen device displays the two-dimensional code interface 10. When it is detected that the folding screen device is switched to the two-dimensional code interface 10, if the two-dimensional code is currently displayed on the first display area, the folding screen device will be fixed on the first display area to display the two-dimensional code interface 10. The change of the screen device posture switches the QR code to the second display area. For example, when the first display area faces upwards, the first display area displays the QR code, the folding screen device is deflected, and the first display area is turned from up to When facing down, the first display area continues to display the two-dimensional code, and the two-dimensional code originally displayed in the first display area will not be switched to display in other display areas because the first display area is turned from up to down.

In the embodiment of the present application, before the folding screen device is deflected, the interface displayed in the first display area may be the first display interface. For example, before the folding screen device is deflected, the first display area displayed by the folding screen device may include a two-dimensional code interface. When the folding screen device detects through the sensor that the deflection angle of the electronic device is greater than the deflection angle threshold, the folding screen device can display the two-dimensional code interface through the first display area. If the first display interface includes a two-dimensional code interface, when it is detected that the deflection angle of the electronic device is greater than the deflection angle threshold, displaying the two-dimensional code interface through the first display area may include the following situations: 1 only display through the first display area The two-dimensional code interface, that is, the two-dimensional code interface 10 fixed on the first display area, will not switch the two-dimensional code to the second display area for display due to the change of the posture of the folding screen device. 2 Simultaneously display the two-dimensional code interface through the first display area and the second display area.

If the first display area displayed by the folding screen device does not contain a QR code interface, when the folding screen device detects through the sensor that the folding screen device is turned from the first display area facing the human face to the second display area facing the human face, the folding screen device In response to the detected deflection angle of the folding screen device being greater than the deflection angle threshold, the first display interface is displayed through the second display area.

As shown in FIG. 4b, the two-dimensional code interface 10 may include: a prompt 101, a two-dimensional code area 102, a two-dimensional code collection option 103, a group collection option 104, a face-to-face red envelope option 105, and a return control 106. Among them, the prompt 101 may display "receipt and payment". The two-dimensional code and barcode displayed in the two-dimensional code area 102 can be scanned by another device to make a payment transaction to an account corresponding to the other device. The QR code collection option 103 can be used to display the collection QR code for another device to scan to receive payment transactions from another device's account. The group payment option 104 is used to initiate payment to contacts in the group chat. The face-to-face red envelope option 105 is used to display the red envelope QR code for another device to scan, so as to make a payment transaction to the account of the other device. The return control 106 is used to return to the upper level interface of the two-dimensional code interface 10. In response to a user operation acting on the return control 106, the folding screen device may display the user interface 20.

When switching to the two-dimensional code interface 10 is detected, if the two-dimensional code interface 10 is currently displayed on the first display area, the foldable screen device is fixed to display the two-dimensional code interface 10 on the first display area. Regardless of the posture of the foldable screen device, and regardless of the state in which the first display area and the second display area are touched, the foldable screen device displays the QR code interface 10 on the first display area, regardless of the posture of the foldable screen device. The QR code is switched to the second display area for display. As shown in Figure 4c, the second display area can be closed. The user can turn the device so that the first display area faces away from the user's face for the barcode scanner to scan the QR code, which improves the convenience of the folding screen device to display the QR code to the barcode scanner.

In another possible implementation manner, when switching to the two-dimensional code interface 10, the folding screen device may display the two-dimensional code interface 10 on both the first display area and the second display area. As shown in FIG. 4d, the two-dimensional code interface 10 displayed on the second display area can be scanned by a code scanner. In another implementation, the user can turn the device so that the first display area faces away from the user's face for the barcode scanner to scan the two-dimensional code. No matter how the user flips the folding screen device or changes the holding state of the folding screen device, the first display area and the second display area of the folding screen device both display the QR code interface for the scanner to scan the QR code, which improves Convenience.

In another possible implementation manner, the display screen is in a folded or unfolded form. When the first display area displays the two-dimensional code interface 10, the folding screen device can display a control on the two-dimensional code interface 10, and the control can respond For user operations, the folding screen device closes the function of automatically switching the display area.

Specifically, as shown in FIG. 4e, when switching to the two-dimensional code interface 10, the first display area can display the two-dimensional code interface 10, and the folding screen device can display a control 1011 on the two-dimensional code interface 10. The second display area can be closed. The folding screen device can turn on the function of automatically switching the display area. The control 1011 may prompt "click on the fixed display area". At this time, the function of automatically switching the display area on the folding screen device is still enabled, that is, the folding screen device can switch the display area for displaying the user interface 10 according to its own posture. In response to a user operation acting on the control 1011, the folding screen device can turn off the function of automatically switching the display area. After the function of automatically switching the display area is turned off, no matter what the posture of the folding screen device is, the folding screen device does not switch the display area for displaying the two-dimensional code interface 10. For example, in response to a user operation on the control 1011, if it is currently displayed on the first display area, the folding screen device is fixed on the first display area to display the QR code interface 10, and the second display area is kept closed without switching Go to the second display area to display.

In a possible implementation manner, when the first display interface is displayed through the first display area, a prompt message is displayed on the first display interface, and in response to a user operation acting on the prompt information, the first display interface is displayed through the second display area. A display interface, or the first display interface is simultaneously displayed through the first display area and the second display area. When the first display interface is simultaneously displayed through the first display area and the second display area, the interfaces displayed in the first display area and the second display area can be the same, or the first display area and the second display area can be combined to display the second display area. One display interface.

In a possible implementation, when the first display interface is displayed through the first display area, the first display interface includes a characteristic user interface (such as a QR code, a video playback interface, or an image interface, etc.), which is displayed on the first display interface. A prompt message, in response to a user operation acting on the prompt message, the first display interface is displayed through the second display area, or the first display interface is simultaneously displayed through the first display area and the second display area. When the first display interface is simultaneously displayed through the first display area and the second display area, the interfaces displayed in the first display area and the second display area can be the same, or the first display area and the second display area can be combined to display the second display area. One display interface.

The control 1012 may prompt "click to automatically switch the display area". The control 1012 is used to re-enable the function of automatically switching the display area.

In some other possible implementation manners of the present application, the display screen is in a folded or expanded form, and when the two-dimensional code interface 10 is displayed in the first display area, the folding screen device may display the first control in the first display area. The first control can respond to a user's operation, so that the foldable screen device displays the two-dimensional code interface 10 in the second display area. Or, the control may respond to a user operation, so that the folding screen device displays the two-dimensional code interface 10 in both the first display area and the second display area. The first control can prompt "click on single screen display". Wherein, the first control is the second prompt information in the embodiment of the present application. In response to a user operation acting on the second prompt information, the foldable screen device displays the specific user interface (such as a two-dimensional user interface) through the second display area. Code interface). In another possible implementation manner, in response to a user operation acting on the second prompt information, the foldable screen device displays the specific user interface through the first display area and the second display area.

In this way, when the first display area faces the human face, the user can touch the control, so that the folding screen device displays the QR code interface in the second display area without the user having to turn the folding screen device. The second display area displays the QR code interface Then it can be scanned by the scanner, which improves the convenience of scanning codes.

Optionally, when switching to the two-dimensional code interface 10, the foldable screen device may display controls on the two-dimensional code interface 10. The controls may respond to user operations so that the foldable screen device is in the first display area and the second display area. The two-dimensional code interface 10 is displayed.

As shown in Figure 12b, the origin O of the geographic coordinate system can be located at the point where the carrier (ie, the device containing the gyroscope sensor, such as the electronic device 100) is located, the X-axis points to the east (E) along the local latitude, and the Y-axis is along the local The meridian points north (N), and the Z axis points upward along the local geographic vertical, and forms a right-handed rectangular coordinate system with the X and Y axes. Among them, the plane formed by the X axis and the Y axis is the local horizontal plane, and the plane formed by the Y axis and the Z axis is the local meridian plane. Therefore, it is understandable that the coordinate system of the gyroscope sensor is: taking the gyroscope sensor as the origin O, pointing east along the local latitude as the X axis, pointing north along the local meridian as the Y axis, and pointing upward along the local geographic vertical (ie The direction of the geographic vertical is the Z axis.

In some embodiments, one or more other sensors may also cooperate to measure the angle α between the first display area and the second display area. For example, each display area of the display screen can be provided with an acceleration sensor in the body. The electronic device 100 (such as the processor 110) can use an acceleration sensor to measure the motion acceleration of each display area when it is rotated; and then calculate the rotation angle of one display area relative to the other display area according to the measured motion acceleration, that is, the first display The angle α between the area and the second display area.

The flip of the electronic device is determined according to the deflection angle of the electronic device. When the deflection angle of the electronic device is greater than the threshold, it can be determined that the electronic device is flipped, and the electronic device is flipped, also known as the electronic device rotating.

Generally, a folding screen device can determine that a display area with an angle of less than 90° from the horizontal plane is a display area facing the human face. In another possible implementation, the folding screen device compares the angles between the two display areas and the horizontal plane. Among the two display areas, the display area with the smaller angle with the horizontal plane may be the display area facing the human face. When the folding screen device detects a change in the display area facing the human face, that is, when the posture of the folding screen device changes, the folding screen device determines that the folding screen device is turned over. For example, if the folding screen device detects through the sensor that the first display area faces the human face and the second display area faces the human face, it is detected that the folding screen device has been turned over. In the embodiment of the present application, the turning is not limited to turning the first display area up to the first display area down, but also includes turning the first display area to the left to the first display area to the right. The deflection angle is greater than the deflection angle threshold, or when it is detected that the rotation angle of the folding screen device is greater than the rotation angle threshold, it can be recognized that the folding screen device is turned over. The embodiment of the application does not limit this.

After that, the electronic device 100 can determine the posture of the folding screen device according to the angle β1 between the first display area and the horizontal plane, and the angle β2 between the second display area and the horizontal plane. The posture of the folding screen device may include, for example, that the first display area faces The human face and the second display area face the human face.

The air pressure sensor 180C is used to measure air pressure. In some embodiments, the electronic device 100 calculates the altitude based on the air pressure value measured by the air pressure sensor 180C to assist positioning and navigation.

The magnetic sensor 180D includes a Hall sensor. The electronic device 100 may use the magnetic sensor 180D to detect the opening and closing of the flip holster. In some embodiments, when the electronic device 100 is a flip machine, the electronic device 100 can detect the opening and closing of the flip according to the magnetic sensor 180D. Furthermore, according to the detected opening and closing state of the leather case or the opening and closing state of the flip cover, features such as automatic unlocking of the flip cover are set.

In some other embodiments of the present application, the Hall sensor may also be located on the body where the two display areas of the foldable display screen are located. When the display screen is in the folded form and the non-folded form, the magnitude of the magnetic field at the inner position of the Hall sensor is different, so that the output signal of the Hall sensor is different. The electronic device 100 determines the opening and closing of the body where the two display areas are located through the electrical signal output by the Hall sensor, so as to determine that the display screen is in a folded or unfolded form (including a flattened form and an unfolded form). When the Hall sensor detects that the display screen is in a folded form, the electronic device 100 can execute the interface display method provided in the embodiment of the present application. When the hall sensor detects that the display screen is in a non-folding form, the electronic device 100 may not execute the interface display method provided in the embodiment of the present application.

The acceleration sensor 180E can detect the magnitude of the acceleration of the electronic device 100 in various directions (generally three axes). When the electronic device 100 is stationary, the magnitude and direction of gravity can be detected.

The electronic device 100 emits infrared light to the outside through the light emitting diode. The electronic device 100 uses a photodiode to detect infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 100. When insufficient reflected light is detected, the electronic device 100 can determine that there is no object near the electronic device 100. The electronic device 100 can use the proximity light sensor 180G to detect that the user holds the electronic device 100 close to the ear to talk, so as to automatically turn off the screen to save power. The proximity light sensor 180G can also be used in leather case mode, and the pocket mode will automatically unlock and lock the screen.

Touch sensor 180K, also called "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch screen is composed of the touch sensor 180K and the display screen 194, which is also called a “touch screen”. The touch sensor 180K is used to detect touch operations acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. The visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K may also be disposed on the surface of the electronic device 100, which is different from the position of the display screen 194.

In the embodiment of the present application, the software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present application takes a layered architecture as an example to illustrate the software structure of the electronic device 100 by way of example. The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Communication between layers through software interface. In some embodiments, the system is divided into four layers, from top to bottom, the application layer, the application framework layer, the system library, and the kernel layer.

Please refer to FIG. 14, which is a software structure block diagram of an electronic device 100 exemplarily provided in an embodiment of the present application.

As shown in Figure 14, the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, WeChat, SMS, etc.

Taking the WeChat application as an example, when the WeChat application detects switching to a specific user interface, such as a QR code interface, it can send a first notification to the information processing module in the application framework layer through the application programming interface. The first notification indicates that the application is currently switching to a specific user interface, such as a QR code interface. It is not limited to WeChat applications, but can also be other applications, such as Alipay, Huawei Wallet, and so on.

In some other embodiments of the present application, the WeChat application may also query whether the current foldable display screen is in a folded form from the angle calculation module in the system library when it detects that it is switched to a specific user interface. When the form of the foldable display screen is a folded form, the first notification is sent to the information processing module in the application framework layer through the application programming interface.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 14, the application framework layer may include an information processing module.

In this embodiment of the application, the information processing module may receive the first notification from the application. After receiving the first notification from the application, the information processing module can notify the display module in the system library that the display area needs to be fixed (that is, turn off the automatic display area switching function), or notify the display module that the first display area and The second display area displays the user interface. For details, refer to the description of step S106 in the example described in FIG. 15 and the description of step S207 in the example described in FIG. 16.

In the embodiment of the present application, the application framework layer may also include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, etc.

The window manager is used to manage window programs. The window manager can obtain the size of the display screen, determine whether there is a status bar, lock the screen, take a screenshot, etc. The content provider is used to store and retrieve data and make these data accessible to applications. The data may include videos, images, audios, phone calls made and received, browsing history and bookmarks, phone book, etc. The view system includes visual controls, such as controls that display text, controls that display pictures, and so on. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface that includes a short message notification icon may include a view that displays text and a view that displays pictures. The phone manager is used to provide the communication function of the second electronic device 200. For example, the management of the call status (including connecting, hanging up, etc.). The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and so on. The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and it can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, and so on. The notification manager can also be a notification that appears in the status bar at the top of the system in the form of a chart or a scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, text messages are prompted in the status bar, prompt sounds, electronic devices vibrate, and indicator lights flash.

The application layer and application framework layer run in a virtual machine. The virtual machine executes the java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The system library can include a display module, and can also include multiple other functional modules. For example: surface manager (surface manager), media library (Media Libraries), 3D graphics processing library (for example: OpenGLES), 2D graphics engine (for example: SGL), etc.

Among them, the display module can be used to receive notifications from the information processing module in the application framework layer. In a scenario where the function of automatically switching the display area is turned off, the display module can turn off the function of automatically switching the display area according to the current form of the display screen and the state in which the function of automatically switching the display area is turned on. For details, refer to steps S106 to S109 in the example described in FIG. 15.

In a scenario where a specific user interface is displayed in the first display area and the second display area at the same time, the display module can notify the display driver to initialize the currently undisplayed screen (for example, the second display area) and set it in the first display area and the second display area. Both are displayed. For details, refer to step S208 in the example described in FIG. 16.

In the embodiment of the present application, the system library may also include an angle calculation module for determining the form of the display screen. The angle calculation module can obtain angle data from the sensor drive of the inner core layer, calculate the opening angle of the display screen, and determine the form of the display screen according to the opening angle, such as flattened form, folded form, or unfolded form. The display module can query the form of the display screen from the angle calculation module. When the form of the display screen is folded, the display module will turn off the function of automatically switching the display area or notify the display driver to display both in the first display area and the second display area. For the specific user interface, refer to steps S107 to S109 in the example described in FIG. 15 for details.

In another possible implementation, an application (such as a WeChat application) can obtain the current display form from the angle calculation module. When the display is in a folded form, the WeChat application sends to the information processing module according to the switched QR code interface For the notification, refer to steps S204 to S206 in the example described in FIG. 16 for details.

The surface manager is used to manage the display subsystem and provides a combination of 2D and 3D layers for multiple applications. The media library supports playback and recording of a variety of commonly used audio and video formats, as well as still image files. The media library can support multiple audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc. The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis, and layer processing. The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer can include display drivers, camera drivers, audio drivers, and sensor drivers.

The display driver is used to receive notifications from the display module. When the notification indication is displayed on the current display area (the first display area), the display driver drives the display screen to display the two-dimensional code interface on the first display area. When the notification instruction is displayed on the first display area and the second display area, the display driver drives the display screen to display the two-dimensional code interface on both the first display area and the second display area.

The sensor driver is used to drive the sensor to detect data. When the acceleration sensor 180E and the gyroscope sensor 180E detect the angle data, the corresponding hardware interrupt is sent to the kernel layer. The sensor driver of the kernel layer sends the angle data to the angle calculation module in the system library.

It should be noted that the functional architecture of the electronic device shown in FIG. 14 is only an implementation manner of the embodiment of the present application. In practical applications, the electronic device may also include more or fewer software modules, which is not limited here.

In the embodiment of the present application, the display module in the software structure shown in FIG. 14 is also used to display the corresponding user interface according to the operation of each software module. The user interface displayed by the display module can refer to the embodiments described in FIGS. 1a to 1b and FIGS. 3a to 10b. The display module may be specifically implemented as the display screen 194 in FIG. 11.

Based on the software architecture diagram shown in FIG. 14, the following specific examples are used to describe the display method in the folding screen device provided in the embodiment of the present application. FIG. 15 is a schematic flowchart of a display method provided by an embodiment of the present application. In the display method, when the folding screen device switches to a specific user interface (for example, a two-dimensional code interface), the folding screen device turns off the function of automatically switching the display area. When the folding screen device exits the specific user interface, the folding screen device can resume the automatic switching display area function.

For the application interface involved in the display method, refer to Figures 4a to 4c and Figures 5a to 5c. As shown in FIG. 15, the display method includes steps S101 to S115.

S101. The angle calculation module receives angle data from the sensor driver.

Among them, the sensor drive can drive a sensor (for example, a gyroscope sensor 180E) to measure angle data. It is not limited to the sensor shown in the example, and the sensor driven by the sensor may also include other sensors that can measure the posture of the folding screen device, such as a Hall sensor, etc., an acceleration sensor, etc. Among them, the Hall sensor can detect the opening and closing of the body where the two display areas are located, so as to determine that the display screen is in a folded form or a non-folded form (including a flat form and an expanded form). For details, refer to the description in the example described in FIG.

S102. The angle calculation module determines the form of the display screen.

In the embodiment of the present application, the form of the display screen may include a flat form, a folded form, and an expanded form. For details, please refer to the aforementioned concept description part. In the embodiment of the present application, the display method provided in the embodiment of the present application is executed only when the display screen is in the folded state or the unfolded state. When the display screen is in a flattened form, the display method provided in the embodiment of the present application may not be executed.

In the embodiment of the present application, the angle calculation module and the sensor drive can continuously detect data to obtain the form of the display screen in real time. S103. The display driver drives the display screen to display the user interface 20 in the first display area.

S104: The WeChat application switches to the two-dimensional code interface, and step S105 is executed.

Among them, the WeChat application may include multiple interfaces (for example, a message list interface, a QR code interface, a chat window interface, a circle of friends interface, etc.). The WeChat application can also contain control logic for switching between various interfaces. The control logic of the interface switching includes the corresponding relationship between the control and the interface content, and the corresponding relationship includes, for example, the corresponding relationship between the payment option 2053d in FIG. 4a and the two-dimensional code interface 10. The following describes the principle of switching the QR code interface of the WeChat application in conjunction with the scenarios shown in Figure 4a to Figure 4b.

When the touch sensor 180K receives a touch operation acting on the position of the option 2053 in FIG. 4a, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes touch operations into original input events (including touch coordinates, time stamps of touch operations, etc.). The original input events are stored in the kernel layer. The application framework layer obtains the original input event from the kernel layer and identifies the control corresponding to the input event. The control corresponding to the touch operation is the payment option 2053d in the user interface 20 of the WeChat application, and the application framework layer notifies the WeChat application of the name of the payment option 2053d. The WeChat application finds the interface content corresponding to the payment option 2053d according to the control logic of interface switching, that is, the two-dimensional code interface, and the WeChat application switches to the two-dimensional code interface. In the embodiment of this application, the QR code interface is, for example, the WeChat payment code 10 shown in Figures 4a and 4b, or it can be a QR code interface that contains personal information in a WeChat application, or it can contain certain account information. , The interface of a certain webpage information, a certain commodity information, or the boarding code, etc., which is not limited in the embodiment of the application. For example, in response to a user operation acting on the payment option 2053d shown in FIG. 4a, the WeChat application can switch to the two-dimensional code interface 10.

In addition, it is not limited to the two-dimensional code interface. When displaying other specific user interfaces, the folding screen device can also turn off the function of automatically switching the display area. That is, the aforementioned specific user interface is not limited to the two-dimensional code interface. Other user interfaces such as the user interface of the gallery, the user interface of the video, etc. The user interface of the gallery can refer to Figure 8a and Figure 8b, and the user interface of the video can include the interface shown in Figure 9, for example.

S105. The WeChat application sends a first notification to the information processing module. The first notification indicates that the QR code interface has been switched.

In the embodiment of the present application, the folding screen device may go through the example setting process shown in FIG. 7a and FIG. 7b, and the information processing module may know on which user interface the function of automatically switching the display area needs to be turned off. For example, as shown in Figure 7b, the two-dimensional code interface (WeChat payment code, WeChat personal business card, Alipay payment code...) and the corresponding options of the user interface of the gallery are selected. In response to the user operation acting on the determining control 403, the information processing module can learn that the function of automatically switching the display area needs to be turned off when the user interface of the two-dimensional code interface or the gallery is displayed. Therefore, when the information processing module receives the first notification from the application, step S106 is executed.

S106. The information processing module sends a second notification to the display module, and the second notification indicates that the display area needs to be fixed and not switched.

In the embodiment of the present application, when the folding screen device is in a folded state, the display area will not be fixed, that is, the function of automatically switching the display area will be turned off. Therefore, before performing step S109, the information processing module needs to perform step S107 to determine the form of the display screen of the current folding screen device.

S107. The display module obtains the current display screen form as the folded form from the angle calculation module, and executes step S108.

In the embodiment of the present application, when the display module obtains the current display screen form from the angle calculation module to be the flat form, the process ends, and steps S108 to S109 are not executed.

S108. The display module detects that the function of automatically switching the display area has been turned on.

In the embodiment of the present application, when the function of automatically switching the display area is turned off, there is no need to perform step S109, and it is only necessary to display on the area currently used for display (such as the first display area).

In the embodiment of the present application, whether the function of automatically switching the display area is turned on can be indicated by a flag, for example, flag 1 indicates that the function of automatically switching the display area is turned on, and flag 0 indicates that the function of automatically switching the display area is turned off. Turning off the function of automatically switching the display area is to set the flag to 0, and turning on the function of automatically switching the display area is to set the flag to 1.

The display module can store the logo. The display module may also record the display area of the currently displayed content, for example, record the display area of the currently displayed content as the first display area. When the flag is 0, the display module notifies the display driver to display content only in the current display area (for example, the first display area). When the flag is 1, the display module obtains the current posture of the folding screen device from the module in the system library, and determines the display area (first display area or second display area) for displaying content according to the current posture of the folding screen device. The modules in the system library can determine the current posture of the folding screen device according to the data detected by the sensor (for example, the gyroscope sensor).

S109. The display module turns off the function of automatically switching the display area.

In the embodiment of the present application, the display module only turns off the function of automatically switching the display area during the display of the specific user interface, such as the two-dimensional code interface. When exiting the QR code interface, as shown in Figures 6a and 6b, for example, in response to a user operation on the return control 106, when the folding screen device displays the user interface 20, the function of automatically switching the display area can be restored again, that is, step S112～S115.

S110. The display module sends a third notification to the display driver, and the third notification indicates that it is displayed on the area currently used for display (for example, the first display area).

In the embodiments of the present application, the area currently used for display refers to the display area used for display in the folding screen device when switching to the two-dimensional code interface, which may be the first display area or the second display area.

S111. The display driver drives the display screen to display the two-dimensional code interface on the first display area.

Wherein, during the period when the display screen displays the two-dimensional code interface, the display driver determines that the display screen displays the two-dimensional code interface on the first display area. Regardless of the posture of the folding screen device, and regardless of the state in which the first display area and the second display area are touched, the folding screen device does not switch the display area for displaying the two-dimensional code interface.

S112. The WeChat application exits the QR code interface.

For example, in the example shown in FIG. 4b, in response to a user operation on the return control 106, the WeChat application may exit the QR code interface. The following describes the principle of the WeChat application exiting the QR code interface in conjunction with the scenarios shown in Figure 6a to Figure 6b.

When the touch sensor 180K receives a touch operation that acts on the position of the return control 106 in FIG. 6a, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes touch operations into original input events (including touch coordinates, time stamps of touch operations, etc.). The original input events are stored in the kernel layer. The application framework layer obtains the original input event from the kernel layer and identifies the control corresponding to the input event. The control corresponding to the touch operation is the return control 106 in the two-dimensional code interface 10, and the application framework layer notifies the WeChat application of the name of the return control 106. The WeChat application finds the interface content corresponding to the return control 106 according to the control logic of interface switching, that is, the user interface 20, and the WeChat application switches to the user interface 20, that is, exits the QR code interface 10.

S113. The WeChat application sends a fourth notification to the information processing module, indicating that the QR code interface has been exited.

S114. The information processing module sends a fifth notification to the display module, indicating that the function of automatically switching the display area needs to be turned on.

S115. The display module turns on the function of automatically switching the display area.

In the embodiment of this application, when the function of automatically switching the display area is turned on, the sensor driver can drive the sensor to detect the device's posture in real time. The display module can determine the display area for displaying content according to the posture of the folding screen device, and drive it to the display. Send a notification so that the display driver drives the first display area or the second display area to display the user interface.

In some other embodiments of the present application, the WeChat application can obtain the current display form from the angle calculation module. Only when the display is in a folded or unfolded form, the WeChat application executes step S104 according to the switched QR code interface. When the display screen is in a flattened form, step S104 is no longer executed. The display module does not need to detect the shape of the display screen, that is, it does not need to perform step S107. In the display method described in FIG. 15, when the folding screen device detects that the first display area or the second display area displays a two-dimensional code interface, the function of automatically switching the display area is closed. In this way, it is convenient for the user to turn the folding screen device so that another device scans the two-dimensional code, which improves the convenience.

Please refer to FIG. 16, which is a schematic flowchart of another display method provided by an embodiment of the present application. In the display method, when the folding screen device switches to a specific user interface (for example, a two-dimensional code interface), the folding screen device can display the specific user interface in both the first display area and the second display area. When the foldable screen device exits the specific user interface, the foldable screen device can restore the state of displaying only on one of the first display area and the second display area.

The application interface involved in the display method can refer to FIG. 4a, FIG. 4b, FIG. 4d, FIG. 6a, and FIG. 6b. As shown in FIG. 16, the display method includes steps S201 to S216.

For details of steps S201 to S204, reference may be made to the description of steps S101 to S104 in the example described in FIG. 16, which will not be repeated here.

S205: The WeChat application queries the angle calculation module for the current display screen form as folded form, and step S206 is executed.

In a possible embodiment, the WeChat application may query the angle calculation module for the current display form. If the form of the current display screen is the folded form, step S206 and subsequent steps are executed. If the form of the current display screen is the flat form, the process ends, and step S206 and subsequent steps are not executed.

S206. The WeChat application sends a first notification to the information processing module. The first notification indicates that the QR code interface has been switched.

Step S206 can be analogous to the description of step S105 in the example described in Figure 15. The folding screen device can also go through the setting process of the example shown in Figure 7a and Figure 7b, and the information processing module can learn which user interfaces require the first display Both the area and the second display area are displayed. For example, as shown in Fig. 7b, the options corresponding to the two-dimensional code interface (WeChat payment code, WeChat personal business card, Alipay payment code...) and the user interface of the gallery are selected. In response to a user operation on the determining control 403, the information processing module can learn that both the first display area and the second display area need to be displayed when the two-dimensional code interface and the user interface of the gallery are displayed. Therefore, when the information processing module receives the first notification from the application, step S207 is executed.

S207. The information processing module sends a sixth notification to the display module, where the sixth notification indicates that both the first display area and the second display area need to be displayed.

When the display module receives the sixth notification, regardless of whether the function of automatically switching the display area is turned on, the display module executes step S208. While the QR code interface is not exited, the display module executes step S208 to notify that the display area is in the first display area. And the steps shown on the second display area.

S208. The display module sends a seventh notification to the display driver, where the seventh notification instructs to initialize the currently undisplayed display area (for example, the second display area) and display it on the first display area and the second display area.

In the embodiment of the present application, the initialization of the second display area may be a reset to prepare the second display area for power-on and display.

S209. The display driver drives the display screen to display the two-dimensional code interface on both the first display area and the second display area.

When both the first display area and the second display area are displayed, the first display area and the second display area each receive one signal. The display content corresponding to the two channels of signals can be the same, for example, both are two-dimensional code interfaces.

S210, the WeChat application exits the two-dimensional code interface, and step S211 is executed.

For example, in the examples shown in FIGS. 6a and 6b, in response to a user operation on the return control 106, the folding screen device may display the user interface 20, and the WeChat application may detect that the QR code interface is exited.

S211. The WeChat application sends a fourth notification to the information processing module, where the fourth notification indicates that the QR code interface has been exited.

For steps S210 to S211, reference may be made to steps S112 to S113 in the example described in FIG. 15, which will not be repeated here.

S212. The information processing module sends an eighth notification to the display module, where the eighth notification indicates that only one display area needs to be restored to display.

In the embodiment of the present application, before step S207, only the user interface is displayed in the first display area, then in step S212, it is restored to display the user interface only on the first display area, for example, the user interface 20 is displayed.

In the embodiment of the present application, the folding screen device may also enable the function of automatically switching the display area. After step S212, the display module may determine a display area for displaying content according to the posture of the folding screen device, and send a notification to the display driver, so that the display driver displays the user interface in the first display area or the second display area.

S213. The display module sends a ninth notification to the display driver, where the ninth notification instructs to close the second display area.

S214. The display module determines that the display area for displaying content is the first display area according to the posture of the folding screen device, and then executes step S215.

S215. The display module sends a tenth notification to the display driver, and the tenth notification indicates that it needs to be displayed in the first display area.

S216. The display driver drives the display screen to display an interface on the first display area.

In the embodiment of the present application, step S214 is continuously executed to realize the function of automatically switching the display area according to the posture of the folding screen device in real time. When the display module detects that the posture of the folding screen device is that the second display area faces the human face, it notifies the display driver to drive the display screen to display in the second display area.

In some other embodiments of the present application, the WeChat application may send the first notification to the information processing module when switching to the two-dimensional code interface, that is, the WeChat application may not need to perform step S205. Before the display module executes step S208, it can also obtain the current display form from the angle calculation module. When the display is in a folded form or an expanded form, the display module executes step S208. When the display screen is in a flattened form, step S208 is no longer executed.
