It should be noted that, for the specific implementation process of this embodiment, reference may be made to the specific implementation process described in the following method, which is not described herein again.

Please refer to FIG. 2A. FIG. 2A is a schematic flowchart of a proximity detection method provided by an embodiment of the present application, which is applied to the above-mentioned electronic device, and the method includes:

Step 201: At a first moment, the electronic device determines a first distance between a target object and the touch display screen through a proximity sensor.

Step 202: At a second moment, the electronic device determines a second distance between the target object and the touch display screen through a proximity sensor, and the first moment is earlier than the second moment.

Step 203 : In the case where the difference between the first distance and the second distance is greater than or equal to a first threshold, the electronic device determines that the target object moves close to the touch display screen.

The target object may be the user's hand, ear, face, and so on.

The first threshold is a positive number, such as 1.5cm, 2cm, 2.5cm or other values.

The number of proximity sensors may be one or more, which is not limited here.

Among them, the proximity sensor can be arranged at any position below the touch display screen, such as the upper left corner of the touch display screen, the middle of the touch display screen, the upper right corner of the touch display screen, and so on.

For example, suppose the distance between the target object and the electronic device is 4cm at the first moment, the first threshold=2cm, and the distance between the target object and the electronic device at the second moment is 2cm, then the difference between the first distance and the second distance is equal to 2cm (equal to the first threshold), at this time, it is determined that the target object moves close to the touch display screen.

At present, the usual way to detect whether an object is approaching the touch screen is to detect whether the value received by the proximity sensor exceeds a preset threshold (such as 150 or 200). Then, it is determined that the target object is moving away, which will cause the target object to shake slightly, and the target object is also detected to be approaching or it is determined that the target object is moving away, and the detection accuracy is not accurate enough.

However, in the embodiment of the present application, when the target object is already close to the touch screen (for example, the user is holding the electronic device while making a phone call, etc.), the electronic device determines whether the target object is approaching by the change in distance , which can eliminate subtle changes and improve detection accuracy.

In an implementation of the present application, the method further includes:

When the difference between the first distance and the second distance is less than or equal to a second threshold, the electronic device determines that the target object moves away from the touch display screen.

Wherein, the second threshold is a negative number, such as -1.5cm, -2cm, -2.5cm or other values.

For example, assuming that the distance between the target object and the electronic device at the first moment is 2cm, the second threshold=2cm, and the distance between the target object and the electronic device at the second moment is 4cm, then the difference between the first distance and the second distance is equal to − 2cm (equal to the second threshold), at this time, it is determined that the target object moves away from the touch screen.

In an implementation manner of the present application, before step 201, the electronic device first starts the sensor proximity detection mode.

Further, under the first condition, the electronic device starts the sensor proximity detection mode, and the first condition is at least one of the following conditions: the electronic device is in a screen-off state, the touch screen of the electronic device is facing upwards, and the electronic device is in a long display (Allways). on display, AOD) mode.

Specifically, since the proximity sensor is arranged under the touch display screen, if the electronic device is in the bright screen state, using the proximity sensor to perform proximity detection will lead to a flickering phenomenon. Therefore, in this application, it is limited to the electronic device in the screen-off state. Only use the proximity sensor for proximity detection, which can avoid the phenomenon of screen splash and improve the display effect.

Specifically, the electronic device includes a gravity sensor, the gravity sensor includes a gravity block and a plurality of piezoelectric crystals disposed on the circumference of the gravity block, and the plurality of piezoelectric crystals are distributed on different sides of the gravity block, as shown in FIG. 2B . In Figure 2B, the gravity sensor includes a gravity block and 6 piezoelectric crystals. These 6 piezoelectric crystals correspond to the 6 surfaces of the electronic device respectively. For example, the piezoelectric crystal 2 corresponds to the touch screen of the electronic device, and the piezoelectric crystal The crystal 3 corresponds to the rear shell of the electronic device, the piezoelectric crystal 1 corresponds to the left side of the electronic device, the piezoelectric crystal 6 corresponds to the right side of the electronic device, the piezoelectric crystal 5 corresponds to the upper side of the electronic device, and the piezoelectric crystal 4 corresponds to the electronic device. the underside of the device.

When the piezoelectric crystal 2 is squeezed by the gravity block, the electrical signal output by the piezoelectric crystal 2 is not 0, and the electronic device detects that the touch display screen of the electronic device is facing downward. When the piezoelectric crystal 3 is squeezed by the gravity block, the electrical signal output by the piezoelectric crystal 3 is not 0, and the electronic device detects that the touch display screen of the electronic device is facing upward.

Specifically, since the proximity sensor is arranged under the touch display screen, when the touch screen display is facing downward (for example, the touch display screen of an electronic device is placed on a table with the touch display screen facing down), if the proximity detection is performed by the proximity sensor, it is detected that the The result is that it is always in the close state, but such detection is meaningless, and may also lead to misoperation of the electronic device and the problem of resource consumption. Therefore, in this application, it is limited to the touch screen of the electronic device facing upwards. Only use the proximity sensor for proximity detection under certain circumstances, which can avoid the above problems and improve the performance of electronic devices.

Specifically, the AOD mode is a display mode in which a specific display area of the touch-sensitive display screen of the electronic device remains constantly on when the screen is locked. In AOD mode, information such as time and notifications can be displayed in a specific display area. Please refer to FIG. 2C . FIG. 2C is a schematic display diagram of an electronic device in an AOD mode provided by an embodiment of the present application. As shown in FIG. 2C , the touch screen includes a specific display area. The specific display area occupies a very small area of the entire touch screen. The specific display area is used to display information such as time and notification messages. Since only the specific area is clicked Bright, the power consumption of AOD mode can be made very low. For users who are accustomed to viewing mobile phones, they do not need to frequently light up the touch screen of electronic devices and unlock electronic devices, which is very convenient.

When the electronic device is in the AOD mode, the proximity sensor is arranged below the touch display screen except for the above-mentioned specific display area.

In an implementation manner of the present application, the method further includes: the electronic device controls the electronic device according to the determined action of the target object.

In an implementation manner of the present application, the electronic device is in a screen-off state, and the electronic device controls the electronic device according to the determined action of the target object, including: an action of approaching the touch display screen when the target object occurs After that, the electronic device performs a screen brightening operation;

After the screen brightening operation is completed, the method further includes: starting the TP proximity detection mode by the electronic device.

In an implementation manner of the present application, the electronic device is in a screen-off state, and the electronic device controls the electronic device according to the determined motion of the target object, including: when the target object moves away from the touch display screen , and when the electronic device is currently in a call state, the electronic device performs a screen-on operation;

After the screen brightening operation is completed, the method further includes: starting the TP proximity detection mode by the electronic device.

Among them, the touch display screen includes a touch screen and a display screen, and the touch screen and the display screen are independently powered and controlled. The TP proximity detection mode is a mode that detects whether the target object is approaching or far away from the touch screen through the touch screen of the touch screen.

Specifically, since the proximity sensor is arranged below the touch-sensitive display screen, if the electronic device is in the bright screen state using the proximity sensor for proximity detection, it will lead to a flickering screen phenomenon. Therefore, in this application, the electronic device is used in the bright screen state. TP proximity detection can avoid the phenomenon of splash screen and improve the display effect.

Specifically, currently, a user holds an electronic device in hand to make a call. Since the electronic device is close to the ear, the proximity sensor detects a proximity state. In this case, the screen is turned off. If during the call, if the distance between the electronic device and the ear fluctuates slightly due to environmental factors (such as the user sitting in the car, the car is bumpy), the proximity sensor detects that the distance is far away, in this case, the screen will be brightened. , in this case, in some scenarios, the status of the touch screen will be on and off for a while.

In the present application, whether the target object is close to the touch screen is determined by the distance difference between the two moments, so as to avoid slight changes in the distance between the electronic device and the target object, which may cause the touch screen to turn on and off for a while. state, which improves the detection accuracy.

Further, after the electronic device starts the TP proximity detection mode, the method further includes:

The electronic device performs TP proximity detection; when it is detected that the target object is far away from the touch screen, the electronic device performs a screen-off operation.

The principle of TP proximity detection is: the electronic device obtains a preset area of the touch screen for proximity detection; the electronic device adjusts the driving voltage of the preset area to increase the effective detection distance of the preset area; the electronic device detects The capacity value data of the preset area; the distance between the target object and the touch screen is determined according to the capacity value data; if the difference between the distances determined before and after is less than or equal to the second threshold, it is determined that the target object is far away from the touch screen. If the difference between the distances determined before and after is greater than or equal to the first threshold, it is determined that the target object is close to the touch screen.

Among them, since the touch screen is used to detect the user's touch operation in a normal state, the driving voltage is generally low. In order to realize the proximity detection, it is necessary to increase the power to realize the detection at a longer distance.

Wherein, the preset area may be one or multiple, which is not limited herein. The preset area may be the entire touch screen, or not the entire touch screen, such as the upper half screen of the touch screen and the like.

In an implementation manner of the present application, the preset area is determined according to multiple pre-stored user call records, and each user call record includes a contact area with the touch screen during the user's call, wherein the multiple user call records The overlapping area of the multiple contact areas in each call record is the user's high-frequency touch area, and this area can be set as a preset area.

Alternatively, the preset area is the upper half screen of the touch screen; wherein, generally, when the user holds the electronic device to make a call, the upper half screen of the electronic device will contact the user's face or ears.

Alternatively, the preset area is an area determined according to the image content collected by the camera. Specifically, the electronic device can collect the current image content through the camera, and determine that the preset part of the user will be contacted according to the current image content, the positional relationship between the camera and the touch screen, and the positional relationship between the current image content and the user's face or ears. preset area.

It can be seen that, in the embodiment of the present application, the electronic device can set the preset area in various ways, so as to improve the flexibility of setting the preset area and the detection accuracy.

In the specific implementation, the electronic device can increase the voltage value of the driving signal, such as 2V to 3.3V, etc. The specific adjustment strategy here can be preset based on the capability information of the touch screen control chip. It can be seen that in the embodiment of the present application, the electronic device can increase the detection power of the touch screen by boosting the voltage, thereby increasing the effective detection distance of the touch screen, thereby realizing proximity detection, and improving the accuracy and success rate of proximity detection.

Wherein, the proximity detection principle of the touch screen is similar to the detection principle of the traditional capacitive touch screen, and specifically, the current sensing of the human body is used to work. Due to the electric field of the human body, each detection unit between the skin of the user and the surface of the touch screen is formed with a coupling capacitance. Within a preset distance range, the capacitance data of the coupling capacitance varies with the distance between the skin of the user and the surface of the touch screen. Therefore, the electronic device can perform distance detection by detecting the capacitance data of each detection unit, thereby realizing proximity detection.

It can be seen that in the embodiment of the present application, when the proximity sensor is arranged below the touch display screen, the sensor proximity detection is used in the off-screen state, and the TP proximity detection is used in the bright-screen state, that is, the display effect is guaranteed. Proximity detection has been implemented to further improve the performance of electronic devices.

Further, the electronic device is currently in a call state, the electronic device performs a screen brightening operation after detecting that the target object moves away from the touch display screen, and after the screen brightening operation is completed, after the electronic device starts the TP proximity detection mode, The method also includes:

After the set duration, if the target object is not detected close to the touch screen, the call audio output by the electronic device has no call content, and the call audio collected by the electronic device has no call content, the electronic device hangs up the current call.

The fact that the call audio has no call content means that the electronic device does not obtain any text information by parsing the call audio. For example, the user who is currently on the call does not speak, and the audio collected by the electronic device is ambient sound, or the user on the other side of the call does not speak, and the audio collected by the other party's electronic device is ambient sound.

It can be seen that, in the embodiment of the present application, when the electronic device is still in a call state, if it is detected that the target object is far away from the touch display screen, and after a period of time, the target object is still far away from the touch screen display screen, then both parties in the call have no further communication. Talking, at this time, both parties may have ended the call, but both parties forgot to hang up the phone. In this case, the electronic device hangs up the current call by itself, which further improves the performance of the electronic device.

In an implementation manner of the present application, the electronic device is currently in an audio output state, and the electronic device controls the electronic device according to the determined action of the target object, including: when the target object approaches the touch display screen After the action, the electronic device turns down the audio output volume; after the target object moves away from the touch display screen, the electronic device turns up the audio output volume.

In specific implementation, lowering or raising the audio output volume can be adjusted according to the difference between the first distance and the second distance. The smaller the difference, the smaller the adjustment range, and the larger the difference, the larger the adjustment range.

In an implementation manner of the present application, the electronic device determines the first distance between the target object and the touch display screen through the proximity sensor, including: the electronic device obtains the first numerical value through the proximity sensor, and determines according to the mapping relationship between the numerical value and the distance The first distance between the target object corresponding to the first value and the touch display screen.

In an implementation manner of the present application, the electronic device determines the second distance between the target object and the touch display screen through the proximity sensor, including: the electronic device obtains the second numerical value through the proximity sensor, and determines according to the mapping relationship between the numerical value and the distance The second distance between the target object corresponding to the second value and the touch display screen.

The first value and the second value may be an energy value, such as light intensity, or a value converted based on the energy value. For example, if the energy value is light intensity, 1 light intensity=10, if the proximity sensor The received light intensity is 10 lux, this value = 100.

Among them, in the mapping relationship between the value and the distance, the larger the value is, the smaller the distance is, and the smaller the value is, the larger the distance is. The mapping relationship between values and distances is shown in Table 1. The values and corresponding distances in Table 1 are obtained through experiments. The specific methods of the experiment are as follows: using a standard occluder placed at a distance of 4cm from the screen, using machine 1 to measure the average value received by the electronic device (for example, 100), and then using machine 2 to measure the average value received by the electronic device (for example, 120 ), and then use the machine 3 to measure the average value (for example, 130) received by the electronic device, etc., and finally calculate the average value based on the average values measured by these several machines, and then obtain the value corresponding to the distance of 4cm in Table 1. The experimental methods at a distance of 1 cm, 2 cm, 3 cm, 5 cm, 6 cm, etc. from the screen are the same as the experimental methods at a distance of 4 cm from the screen, and will not be described here.

Table 1

Numerical value distance 330 1cm 230 2cm 165 3cm 116 4cm 73 6cm ... ...

It can be seen that, in the embodiment of the present application, a standard mapping relationship obtained by an experiment is imported into the electronic device in advance, and the subsequent electronic device can determine the distance through this mapping relationship. The operation is simple, and the proximity sensor can detect the distance.

Consistent with the embodiment shown in FIG. 2A, please refer to FIG. 3. FIG. 3 is a schematic flowchart of a proximity detection method provided by an embodiment of the present application, which is applied to the above-mentioned electronic equipment. The proximity detection method includes:

Step 301: At the first moment, the electronic device acquires the first value through the proximity sensor.

Step 302: The electronic device determines a first distance between the target object corresponding to the first numerical value and the touch display screen according to the mapping relationship between the numerical value and the distance.

Step 303: At the second moment, the electronic device acquires the second value through the proximity sensor.
