Detailed ways

In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Currently, electronic devices can be used for screen projection. Generally, electronic devices need to install third-party screen projection applications and use third-party screen projection applications to project the screen. After the electronic device successfully projects the screen, if it is not connected to a power source, then after a period of inactivity, the electronic device will lock the screen and enter Doze mode, and the screen projection application will switch to the background operation of the electronic device accordingly. However, in Doze mode, the screen projection application will be subject to the following restrictions: 1. Suspend access to the network; 2. The system will ignore wake locks; 3. AlarmManager (alarm service) alarms will be postponed to the next maintenance period; 4. The system does not perform Wi-Fi scans; 5. The system does not allow data synchronization to run; 6. The system does not allow JobScheduler to run. Therefore, the screen projection application or the one running on the screen projection Other applications in the application will run abnormally.

In view of the above problems, the inventors have discovered after long-term research and proposed the screen projection method, device, electronic device and storage medium provided in the embodiments of the present application. By setting the screen off time of the electronic device to non-screen off during the screen projection process, the risk of the system screen off restricting the application operation and causing the application to run abnormally can be avoided. Among them, the specific screen projection method is described in detail in the subsequent embodiments.

The following describes the application environment of the screen projection method provided in the embodiment of the present application.

Please refer to Figure 1, which shows a schematic diagram of an application environment that can be used for the screen projection method provided in an embodiment of the present application. As shown in Figure 1, it includes an electronic device 100 and a display device 200, and the electronic device 100 can project the screen on the display device 200. Among them, the electronic device 100 may include a smart phone, a tablet computer, a wearable device, and other devices with a screen projection application installed, and the display device 200 may include a display screen, a smart TV, and other devices with display functions. In this embodiment, the electronic device 100 and the display device 200 can be connected, or the electronic device 100 and the display device can be in the same local area network, which is not limited here.

Please refer to Figure 2, which shows a flow chart of a screen projection method provided by an embodiment of the present application. The screen projection method is used to avoid the risk of the system restricting the application from running due to the screen off time by setting the screen off time of the electronic device to non-screen off during the screen projection process, thereby causing abnormal operation of the application. In a specific embodiment, the screen projection method is applied to a screen projection device 300 as shown in Figure 12 and an electronic device 100 (Figure 13) equipped with the screen projection device 300. The following will take an electronic device as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the electronic device used in this embodiment may include smart phones, tablet computers, wearable electronic devices, etc., which are not limited here. The process shown in Figure 2 will be elaborated in detail below. The screen projection method may specifically include the following steps:

Step S110: In response to the screen projection instruction, create a screen projection item for the electronic device.

In this embodiment, the electronic device can detect whether a screen projection instruction is received. If it is detected that a screen projection instruction is received, it can create a screen projection event of the electronic device in response to the screen projection instruction.

As a method, the electronic device can detect whether the first target voice information is received. If it is detected that the first target voice information is received, it can be determined that the screen projection instruction is received. For example, if it is determined that the voice information of "cast the screen to the display device" is received, it can be determined that the screen projection instruction is received.

As another way, the electronic device can detect whether it has received a first target operation acting on a physical key of the electronic device. If it is detected that the first target operation acting on a physical key of the electronic device has been received, it can be determined that the screen projection instruction has been received. For example, if it is determined that the first long press operation, the first press operation, etc. acting on the power button of the electronic device have been received, it can be determined that the screen projection instruction has been received.

As another way, the electronic device can detect whether a second target operation acting on a virtual key of the electronic device is received. If it is detected that a second target operation acting on a target virtual key of the electronic device is received, it can be determined that a screen projection instruction is received. For example, if it is determined that a second click operation is received on an application icon of a screen projection application installed on the electronic device, a second click operation is received on a screen projection control corresponding to the screen projection application installed on the electronic device, etc., it can be determined that a screen projection instruction is received.

As another way, the electronic device can detect whether a third target operation acting on the touch screen of the electronic device is received. If it is detected that the third target operation acting on the touch screen of the electronic device is received, it can be determined that the screen projection instruction is received. For example, if it is determined that a third sliding operation, a third click operation, etc. acting on the touch screen of the electronic device are received, it can be determined that the screen projection instruction is received.

In some embodiments, the process of creating a screen projection event for an electronic device and a display device is described by taking the creation of a screen projection event for an electronic device as an example. The electronic device and the display device are connected to the same wireless local area network, and the screen projection service is turned on the display device. The display device will broadcast its own IP address and port number to the local area network. The screen projection function is turned on the electronic device, and the electronic device automatically searches for available devices in the current wireless local area network, finds the corresponding display device, and clicks to connect. The electronic device will send a connection request to the display device according to the IP address and port number of the display device. The connection request sent carries the IP address and port number of the electronic device. After the display device receives the connection request sent by the electronic device, it establishes a wireless connection with the electronic device, and sends a connection success confirmation message to the electronic device according to the IP address and port number of the electronic device. After the electronic device receives the connection success confirmation message, it displays that the connection is successful. The electronic device mobile phone selects the playback content that needs to be projected to the display device for screen projection playback. The electronic device transmits the playback content to the display device through the wireless local area network. After the display device receives the playback content, it plays it on the display device.

Step S120: If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be turned off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state.

It is understandable that if an electronic device keeps the screen on for a long time without receiving a keep-screen-on operation (such as a touch screen operation) or an event (such as a call notification), it will increase power consumption. Therefore, in order to reduce power consumption, the electronic device can set a screen-off time, and automatically enter the screen-off state when the screen-off time is reached. Generally, the screen-off time can generally include 30 seconds, 1 minute, 2 minutes, no screen-off, etc. Among them, if the screen-off time is 30 seconds, it means that the electronic device automatically enters the screen-off state if it does not receive a keep-screen-on operation or event for 30 seconds; if the screen-off time is 1 minute, it means that the electronic device automatically enters the screen-off state if it does not receive a keep-screen-on operation or event for 1 minute; if the screen-off time is no screen-off, it means that the electronic device will not automatically enter the screen-off state even if it does not receive a keep-screen-on operation or event for a long time.

In this embodiment, after creating a screen projection event, the electronic device can determine whether the screen projection is successful based on the screen projection event. If it is determined that the screen projection is successful based on the screen projection event, the screen off time of the electronic device can be set to not to be off, thereby ensuring that the electronic device will not automatically enter the screen off state during the screen projection process, and avoiding the system screen off limiting the application operation, causing the application to run abnormally. If it is determined that the screen projection based on the screen projection event is unsuccessful, the screen off time of the electronic device may not be set to non-screen off, and it is continued to be determined whether the screen projection based on the screen projection event is successful.

In some embodiments, based on the above-mentioned examples of electronic devices and display devices, the electronic device can detect whether a connection success confirmation message sent by the display device is received. If it is determined that the electronic device receives the connection success confirmation message sent by the display device, it can be determined that the screen projection based on the screen projection matter is successful. If it is determined that the electronic device does not receive the connection success confirmation message sent by the display device, it can be determined that the screen projection based on the screen projection matter is unsuccessful.

In some embodiments, if the screen projection is successful based on the projection event, the initial screen off time of the electronic device (the currently set screen off time) can be detected, and based on the initial screen off time, the screen off time of the electronic device can be set to not be on. Optionally, if it is detected that the initial screen off time of the electronic device is not not to be on (such as the initial screen off time is 30 seconds, 1 minute, etc.), the screen off time of the electronic device can be modified to not be on; if it is detected that the initial screen off time of the electronic device is not to be on, the screen off time of the electronic device can be kept as not to be on.

Please refer to Figure 3, which shows an application schematic diagram of the screen projection method provided in an embodiment of the present application. As shown in Figure 3, when the electronic device 100 successfully projects the screen on the display device 200, the electronic device 100 can continue to display the screen.

A screen projection method provided in an embodiment of the present application creates a screen projection event for an electronic device in response to a screen projection instruction. If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be on, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state. Therefore, by setting the screen off time of the electronic device to not be on during the screen projection process, the risk of the system screen off restricting the operation of the projection application and causing abnormal operation of the projection application can be avoided.

Please refer to Figure 4, which shows a schematic diagram of the process of the screen projection method provided by an embodiment of the present application. The method is applied to the above-mentioned electronic device. The process shown in Figure 4 will be described in detail below. The screen projection method may specifically include the following steps:

Step S210: In response to the screen projection instruction, create a screen projection item for the electronic device.

Step S220: If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be turned off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state.

For the detailed description of step S210 to step S220, please refer to step S110 to step S120, which will not be repeated here.

Step S230: If the screen projection is successful based on the screen projection event, the display brightness of the electronic device is set to the minimum display brightness.

In this embodiment, after creating a screen projection event, the electronic device can determine whether the screen projection is successful based on the screen projection event. If it is determined that the screen projection is successful based on the screen projection event, the display brightness of the electronic device can be set to the minimum display brightness, thereby reducing the power consumption of the electronic device during the screen projection process. If it is determined that the screen projection is unsuccessful based on the screen projection event, the display brightness of the electronic device may not be set to the minimum display brightness, and the screen projection is determined based on whether the screen projection is successful based on the screen projection event.

In some embodiments, during the use of the electronic device before the screen projection is successful, the display brightness of the electronic device is generally the target display brightness, wherein the target display brightness is the display brightness of the electronic device in normal use, and the target display brightness is greater than the minimum display brightness. If it is determined that the screen projection based on the screen projection event is successful, the display brightness of the electronic device can be reduced from the target display brightness to the minimum display brightness; if it is determined that the screen projection based on the screen projection event is unsuccessful, the display brightness of the electronic device can be maintained at the target display brightness to ensure the normal use of the electronic device.

As an implementable manner, the electronic device may be pre-set and stored with a minimum display brightness, for example, the electronic device may be pre-set and stored with a minimum display brightness when it is factory set. Then, if it is determined that the screen projection based on the projection event is successful, the display brightness of the electronic device may be set to the pre-set and stored minimum display brightness.

Please refer to Figure 5, which shows another application schematic diagram of the screen projection method provided in an embodiment of the present application. As shown in Figure 5, when the electronic device 100 successfully projects the screen on the display device 200, the electronic device 100 can display at the lowest display brightness.

Step S240: intercepting a touch event on the touch screen of the electronic device.

In this embodiment, when the display brightness of the electronic device is set to the lowest display brightness and the electronic device is displayed at the lowest display brightness, touch events on the touch screen of the electronic device can be intercepted, thereby preventing the user from triggering erroneous operations on the touch screen of the electronic device and affecting the screen projection effect when the electronic device is projecting the screen at the lowest display brightness.

In some embodiments, intercepting touch events on the touch screen of the electronic device may include: intercepting a sliding operation on the touch screen of the electronic device, intercepting a clicking operation on the touch screen of the electronic device, intercepting a pressing operation on the electronic device, etc., which are not limited here.

As an implementable manner, when the electronic device is displaying at the lowest display brightness, the touch events on the touch screen of the electronic device can be intercepted by not detecting the touch events acting on the touch screen of the electronic device.

As another practicable manner, when the electronic device is displaying at the lowest display brightness, the touch events on the touch screen of the electronic device can be intercepted by not responding to the detected touch events acting on the touch screen of the electronic device.

In some embodiments, if the display brightness of the electronic device is adjusted from the minimum display brightness to the target display brightness, the interception of touch events on the touch screen of the electronic device can be stopped, that is, if the display brightness of the electronic device is adjusted from the minimum display brightness to the target display brightness, the interception of touch events on the touch screen of the electronic device can be stopped. As an implementable manner, if the display brightness of the electronic device is adjusted from the minimum display brightness to the target display brightness, and during the display at the target display brightness, the touch event acting on the touch screen of the electronic device can be detected, and when the touch event acting on the touch screen of the electronic device is detected, the touch event is responded to.

The screen projection method provided in one embodiment of the present application creates a screen projection event for an electronic device in response to a screen projection instruction. If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be on, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state, the display brightness of the electronic device is set to the minimum display brightness, and the touch events for the touch screen of the electronic device are intercepted. Compared with the screen projection method shown in FIG2, this embodiment also sets the display brightness of the electronic device to the minimum display brightness to reduce the power consumption of the electronic device. In addition, the touch events for the touch screen of the electronic device are intercepted, which can avoid misoperation during the screen projection process and improve the screen projection effect.

Please refer to Figure 6, which shows a schematic diagram of the process of the screen projection method provided by an embodiment of the present application. The method is applied to the above-mentioned electronic device. The process shown in Figure 6 will be described in detail below. The screen projection method may specifically include the following steps:

Step S310: In response to the screen projection instruction, create a screen projection item for the electronic device.

Step S320: If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be turned off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state.

For the detailed description of step S310 to step S320, please refer to step S110 to step S120, which will not be repeated here.

Step S330: If the screen projection is successful based on the screen projection event, the display brightness of the electronic device is set to the minimum display brightness.

For the detailed description of step S330, please refer to step S230, which will not be repeated here.

Step S340: If the screen projection is completed, the display brightness of the electronic device is adjusted from the minimum display brightness to the target display brightness, wherein the target display brightness is greater than the minimum display brightness.

In this embodiment, the electronic device can detect whether the screen projection is finished during the process of screen projection at the minimum display brightness. If it is detected that the screen projection is finished, the display brightness of the electronic device can be adjusted from the minimum display brightness to the target display brightness to ensure the normal use of the electronic device. If it is detected that the screen projection is not finished, the display brightness of the electronic device can be maintained at the minimum display brightness.

In some embodiments, since the target display brightness is greater than the minimum display brightness, when the end of screen projection is detected, the display brightness of the electronic device can be increased from the minimum display brightness to the target display brightness. As an implementable method, when the screen projection of the electronic device is successful and the display brightness of the electronic device is set to the minimum display brightness, the display brightness of the electronic device can be reduced from the target display brightness to the minimum display brightness. At this time, the target display brightness of the electronic device can be recorded. Afterwards, when the screen projection is completed, the electronic device can determine the target display brightness based on the record of the electronic device, and increase the display brightness of the electronic device from the minimum display brightness to the target display brightness of the record, thereby ensuring that the display brightness of the electronic device remains unchanged when the user is in normal use, which can be more in line with the user's usage habits and improve the user's usage experience.

In some embodiments, the electronic device can detect whether a screen projection end instruction is received. If it is detected that a screen projection end instruction is received, the display brightness of the electronic device can be adjusted from the minimum display brightness to the target display brightness in response to the screen projection end instruction.

As a method, the electronic device can detect whether the second target voice information is received. If it is detected that the second target voice information is received, it can be determined that the screen projection end instruction is received. For example, if it is determined that the voice information of "end screen projection" is received, it can be determined that the screen projection end instruction is received.

As another way, the electronic device can detect whether it has received a fourth target operation acting on a physical key of the electronic device. If it is detected that the fourth target operation acting on the physical key of the electronic device has been received, it can be determined that the projection end instruction has been received. For example, if it is determined that the fourth long press operation, the fourth press operation, etc. acting on the power button of the electronic device have been received, it can be determined that the screen projection end instruction has been received.

As another way, the electronic device can detect whether the fifth target operation of the virtual key of the electronic device is received. If it is detected that the fifth target operation of the target virtual key of the electronic device is received, it can be determined that the screen projection end instruction is received. For example, if it is determined that the fifth click operation of the screen projection end control corresponding to the installed screen projection application on the electronic device is received, it can be determined that the screen projection end instruction is received.

As another way, the electronic device can detect whether the sixth target operation acting on the touch screen of the electronic device is received. If it is detected that the sixth target operation acting on the touch screen of the electronic device is received, it can be determined that the screen projection end instruction is received. For example, if it is determined that the sixth sliding operation, the sixth click operation, etc. acting on the touch screen of the electronic device are received, it can be determined that the screen projection end instruction is received.

The screen projection method provided in one embodiment of the present application creates a screen projection event for an electronic device in response to a screen projection instruction. If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state, and the display brightness of the electronic device is set to the minimum display brightness. If the screen projection ends, the display brightness of the electronic device is adjusted from the minimum display brightness to the target display brightness, wherein the target display brightness is greater than the minimum display brightness. Compared with the screen projection method shown in FIG2, this embodiment also sets the display brightness of the electronic device to the minimum display brightness to reduce the power consumption of the electronic device. In addition, when the screen projection ends, the display brightness of the electronic device is restored to normal to improve the user experience.

Please refer to Figure 7, which shows a schematic diagram of the process of the screen projection method provided by an embodiment of the present application. The method is applied to the above-mentioned electronic device. The process shown in Figure 7 will be described in detail below. The screen projection method may specifically include the following steps:

Step S410: In response to the screen projection instruction, create a screen projection item for the electronic device.

Step S420: If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be turned off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state.

For the detailed description of step S410 to step S420, please refer to step S110 to step S120, which will not be repeated here.

Step S430: If the screen projection is successful based on the screen projection event, the display brightness of the electronic device is set to the minimum display brightness.

For the detailed description of step S430, please refer to step S230, which will not be repeated here.

Step S440: In response to an incoming call event for the electronic device, adjusting the display brightness of the electronic device from the minimum display brightness to a target display brightness, wherein the target display brightness is greater than the minimum display brightness.

In this embodiment, the electronic device can monitor whether an incoming call event for the electronic device is received during the screen projection at the minimum display brightness. In response to the incoming call event for the electronic device, the display brightness of the electronic device can be adjusted from the minimum display brightness to the target display brightness to ensure the normal call answering of the electronic device. If the incoming call event of the electronic device is not monitored, the display brightness of the electronic device can be maintained at the minimum display brightness.

In some embodiments, since the target display brightness is greater than the minimum display brightness, when an incoming call event to the electronic device is monitored, the display brightness of the electronic device can be increased from the minimum display brightness to the target display brightness. As an implementable method, when the electronic device successfully projects the screen and the display brightness of the electronic device is set to the minimum display brightness, the display brightness of the electronic device can be reduced from the target display brightness to the minimum display brightness. At this time, the target display brightness of the electronic device can be recorded. Afterwards, when the electronic device monitors an incoming call event to the electronic device, the target display brightness can be determined based on the record of the electronic device, and the display brightness of the electronic device can be increased from the minimum display brightness to the target display brightness of the record.

In some embodiments, an incoming call event to an electronic device may include: an incoming call event to an electronic device via a telephone call; an incoming call event to an electronic device via a voice call; an incoming call event to an electronic device via a video call, etc., which are not limited here.

Step S450: In response to a first pressing event of a power key of the electronic device, adjusting the display brightness of the electronic device from the minimum display brightness to the target display brightness.

In this embodiment, the electronic device can monitor whether the first pressing event of the power key of the electronic device is received during the process of projecting the screen at the minimum display brightness. In response to the first pressing event of the power key of the electronic device, the display brightness of the electronic device can be adjusted from the minimum display brightness to the target display brightness. At this time, the electronic device projects the screen at the target display brightness. If the first pressing event of the power key of the electronic device is not monitored, the display brightness of the electronic device can be maintained at the minimum display brightness.

In some embodiments, since the target display brightness is greater than the minimum display brightness, when the first pressing event of the power button of the electronic device is monitored, the display brightness of the electronic device can be increased from the minimum display brightness to the target display brightness. As an implementable method, when the electronic device successfully projects the screen and the display brightness of the electronic device is set to the minimum display brightness, the display brightness of the electronic device can be reduced from the target display brightness to the minimum display brightness. At this time, the target display brightness of the electronic device can be recorded. Afterwards, when the electronic device monitors the first pressing event of the power button of the electronic device, the target display brightness can be determined based on the record of the electronic device, and the display brightness of the electronic device can be increased from the minimum display brightness to the target display brightness of the record.

In some embodiments, the first pressing event for the power key of the electronic device may include: a pressing operation on the power key of the electronic device.

Step S460: In response to a second pressing event on the power key of the electronic device, adjusting the display brightness of the electronic device from the target display brightness to the minimum display brightness.

In this embodiment, the electronic device can monitor whether a second press event for the power button of the electronic device is received during the process of projecting the screen at the target display brightness. In response to the second press event for the power button of the electronic device, the display brightness of the electronic device can be adjusted from the target display brightness to the minimum display brightness. At this time, the electronic device projects the screen at the minimum display brightness. If the second press event for the power button of the electronic device is not monitored, the display brightness of the electronic device can be maintained at the target display brightness. Based on this, it is possible to control the display brightness of the electronic device to switch between the minimum display brightness and the target display brightness by acting on the press event of the power button of the electronic device, which can enhance the user's interactive experience.

In some embodiments, since the target display brightness is greater than the minimum display brightness, when a second press event of the power button of the electronic device is monitored, the display brightness of the electronic device can be reduced from the target display brightness to the minimum display brightness.

In some embodiments, the second pressing event for the power key of the electronic device may include: a pressing operation on the power key of the electronic device.

The screen projection method provided by an embodiment of the present application, in response to a screen projection instruction, creates a screen projection event of an electronic device, if the screen projection is successful based on the screen projection event, then sets the screen off time of the electronic device to not be screen off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state, sets the display brightness of the electronic device to the minimum display brightness, in response to an incoming call event of the electronic device, adjusts the display brightness of the electronic device from the minimum display brightness to the target display brightness, wherein the target display brightness is greater than the minimum display brightness, in response to a first pressing event of the power button of the electronic device, adjusts the display brightness of the electronic device from the minimum display brightness to the target display brightness, and in response to a second pressing event of the power button of the electronic device, adjusts the display brightness of the electronic device from the target display brightness to the minimum display brightness. Compared with the screen projection method shown in FIG. 2, this embodiment also sets the display brightness of the electronic device to the minimum display brightness to reduce the power consumption of the electronic device.

Please refer to Figure 8, which shows a schematic diagram of the process of the screen projection method provided by an embodiment of the present application. The method is applied to the above-mentioned electronic device. The process shown in Figure 8 will be described in detail below. The screen projection method may specifically include the following steps:

Step S510: In response to the screen projection instruction, create a screen projection item for the electronic device.

Step S520: If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be turned off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state.

For the detailed description of step S510 to step S520, please refer to step S110 to step S120, which will not be repeated here.

Step S530: If the screen projection is completed, the screen off time of the electronic device is restored to the initial screen off time set before the screen projection is successful.

In this embodiment, during the screen projection process, the electronic device can detect whether the screen projection has ended. If it is detected that the screen projection has ended, the screen off time of the electronic device can be restored to the initial screen off time set before the screen projection is successful, so as to ensure the normal use of the electronic device. If it is detected that the screen projection has not ended, the screen off time of the electronic device can be kept as non-screen off.

In some embodiments, when the screen is projected successfully, the electronic device can adjust the screen-off time of the electronic device from the initial screen-off time (such as 30 seconds, 1 minute, etc.) to no screen off. At this time, the initial screen-off time of the electronic device can be recorded. Afterwards, when the screen projection is completed, the electronic device can determine the initial screen-off time based on the record of the electronic device, and reset the screen-off time of the electronic device from no screen off to the initial screen-off time, thereby ensuring that the screen-off time of the electronic device remains unchanged when the user is in normal use, which can be more in line with the user's usage habits and enhance the user's usage experience.

The screen projection method provided in an embodiment of the present application creates a screen projection event of an electronic device in response to a screen projection instruction. If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state. If the screen projection ends, the screen off time of the electronic device is restored to the initial screen off time set before the screen projection is successful. Compared with the screen projection method shown in FIG2, this embodiment also restores the initial screen off time when the screen projection ends, so as to reduce the impact on user use and improve the user experience.

Please refer to Figure 9, which shows a schematic diagram of the process of a screen projection method provided by an embodiment of the present application. The method is applied to the above-mentioned electronic device. The process shown in Figure 9 will be described in detail below. The screen projection method may specifically include the following steps:

Step S610: In response to the screen projection instruction, create a screen projection item for the electronic device.

Step S620: If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be turned off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state.

For the detailed description of step S610 to step S620, please refer to step S110 to step S120, which will not be repeated here.

Step S630: If the screen projection is successful based on the projection matter, a target application that does not meet the preset type is determined from the applications running in the background of the electronic device.

In some embodiments, the electronic device may be pre-set and stored with a preset type, which is used as a basis for judging the application running on the electronic device. Therefore, in this embodiment, when it is determined that the screen projection is successful based on the projection event, the application running in the background of the electronic device may be compared with the preset type to determine whether the application running in the background of the electronic device meets the preset type. If it is determined based on the above judgment result that the application meets the preset type, the application may not be determined as the target application; if it is determined based on the above judgment result that the application does not meet the preset type, the application may be determined as the target application.

As an implementable manner, the preset type may be a type whose operating power consumption is lower than a power consumption threshold. That is, if the operating power consumption of the first application running in the background of the electronic device is lower than the power consumption threshold, it can be considered that the first application meets the preset type; if the operating power consumption of the first application running in the background of the electronic device is higher than the power consumption threshold, it can be considered that the first application does not meet the preset type. Based on this, in this embodiment, if it is determined that the first application running in the background of the electronic device meets the preset type, it can be considered that the power consumption caused by the first application running in the background of the electronic device is low, and the first application may not be determined as the target application; if it is determined that the application running in the background of the electronic device does not meet the preset type, it can be considered that the power consumption caused by the first application running in the background of the electronic device is high, and the application may be determined as the target application.

As another practicable method, the preset type may be an instant messaging type. That is, if the second application running in the background of the electronic device is of an instant messaging type, it can be considered that the second application meets the preset type; if the second application running in the background of the electronic device is not of an instant messaging type, it can be considered that the second application does not meet the preset type. Based on this, in this embodiment, if it is determined that the second application running in the background of the electronic device meets the preset type, it can be considered that the second application needs to receive messages and pop up prompts in a timely manner, and the second application may not be determined as the target application; if it is determined that the second application running in the background of the electronic device does not meet the preset type, it can be considered that the second application does not need to receive messages and pop up prompts in a timely manner, and the second application may be determined as the target application.

As another implementable method, the preset type may be a reading type. That is, if the type of the third application running in the background of the electronic device is a reading type, then it can be considered that the third application meets the preset type; if the type of the third application running in the background of the electronic device is not a reading type, then it can be considered that the third application does not meet the preset type. Based on this, in this embodiment, if it is determined that the third application running in the background of the electronic device meets the preset type, then it can be considered that when the third application runs in the foreground again, it is necessary to locate the current reading position, and the third application may not be determined as the target application; if it is determined that the third application running in the background of the electronic device does not meet the preset type, then it can be considered that when the third application runs in the foreground again, it is not necessary to locate the current reading position. The third application may then be determined as the target application.

Please refer to Figure 10, which shows a schematic flow chart of step S630 of the screen projection method shown in Figure 9 of the present application. The process shown in Figure 10 will be described in detail below. The method may specifically include the following steps:

Step S631: If the screen projection is successful based on the screen projection event, the remaining power of the electronic device is obtained.

In some implementations, if the screen projection is successful based on the screen projection event, the remaining power of the electronic device can be obtained.

As an implementable method, if the screen is projected successfully based on the projection matter and during the projection process, the remaining power of the electronic device can be obtained in real time, the remaining power of the electronic device can be obtained at preset time intervals, the remaining power of the electronic device can be obtained at preset time points, or the remaining power of the electronic device can be obtained according to other preset rules, etc., which are not limited here.

Step S632: If the remaining power is lower than the remaining power threshold, a target application that does not meet a preset type is determined from the applications running in the background of the electronic device.

In some embodiments, the electronic device may pre-set and store a remaining power threshold, which is used as a basis for determining the remaining power of the electronic device. Therefore, in this embodiment, when the remaining power of the electronic device is obtained, the remaining power can be compared with the remaining power threshold to determine whether the remaining power is lower than the remaining power threshold. Optionally, the remaining power threshold may include 30%, 20%, etc., which is not limited here.

Among them, if it is determined that the remaining power is lower than the remaining power threshold, it can be indicated that the remaining power of the electronic device is insufficient. The target application that does not meet the preset type can be determined from the applications running in the background of the electronic device, and the target application can be closed to reduce the power consumption of the electronic device and increase the usage time of the screen projection.

If it is determined that the remaining power is greater than or equal to the remaining power threshold, it can be indicated that the remaining power of the electronic device is sufficient, and the application running in the background of the electronic device does not need to be closed.

Step S640: close the target application.

In this embodiment, when the target application is determined, the target application can be closed, that is, the target application can be deleted from the background of the electronic device. Based on this, the power consumption of the electronic device can be reduced to increase the usage time of the screen projection.

The screen projection method provided in one embodiment of the present application creates a screen projection event of the electronic device in response to a screen projection instruction. If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state, and the target application that does not meet the preset type is determined from the applications running in the background of the electronic device, and the target application is closed. Compared with the screen projection method shown in FIG2, this embodiment can also close the target application that does not meet the preset type running in the background of the electronic device, which can reduce the power consumption of the electronic device and increase the use time of the screen projection.

Please refer to Figure 11, which shows a schematic diagram of the process of the screen projection method provided by an embodiment of the present application. The method is applied to the above-mentioned electronic device. The process shown in Figure 11 will be described in detail below. The screen projection method may specifically include the following steps:

Step S710: In response to a screen projection instruction, determine the screen projection method indicated by the screen projection instruction.

In this embodiment, when a screen projection instruction is received, the screen projection method indicated by the screen projection instruction can be determined in response to the screen projection instruction.

Optionally, the screen projection instruction may carry the screen projection method desired by the user, so when the electronic device receives the screen projection instruction, it may parse the screen projection instruction to obtain the screen projection method indicated by the screen projection instruction. In some embodiments, when the user triggers screen projection through the electronic device, the electronic device may output prompt information, wherein the prompt information is used to prompt the selection of the screen projection method, and the user may select the screen projection method based on the prompt information, thereby determining the screen projection method indicated by the screen projection instruction.

As an implementable method, when a user triggers screen projection through an electronic device, the electronic device can output a prompt message, wherein the prompt message can be used to prompt the user to determine the projection mode from a first projection mode and a second projection mode, wherein the first projection mode represents a projection mode with the screen off, and the second projection mode represents a projection mode without the screen off.

Step S720: Based on the screen projection method, create a screen projection item for the electronic device.

In this embodiment, when the screen projection method is determined, the screen projection items of the electronic device can be created based on the screen projection method.

In some implementations, if the determined screen projection method is the first screen projection method, a screen-off projection event can be created; if the determined screen projection method is the second screen projection method, a screen-non-screen-off projection event can be created.

Step S730: If the screen projection is successful based on the screen projection event, the screen off time of the electronic device is set to not be turned off, wherein the screen off time is used to indicate the time when the electronic device automatically enters the screen off state.

For the detailed description of step S730, please refer to step S120, which will not be repeated here.

The screen projection method provided in an embodiment of the present application responds to a screen projection instruction, determines the screen projection mode indicated by the screen projection instruction, creates a screen projection event for the electronic device based on the screen projection mode, and if the screen projection is successful based on the screen projection event, sets the screen off time of the electronic device to not be off, wherein the screen off time is used to indicate an event in which the electronic device automatically enters the screen off state.
