It should be noted that, the specific implementation process of the present embodiment may refer to the specific implementation process described in the following method, and is not described here.

Referring to fig. 2A, fig. 2A is a schematic flowchart of a proximity detection method according to an embodiment of the present application, and the method is applied to the electronic device, and the method includes:

step 201: at a first moment, the electronic equipment determines a first distance between a target object and the touch display screen through a proximity sensor.

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

Step 203: and under the condition that the difference value of the first distance and the second distance is larger than or equal to a first threshold value, the electronic equipment determines that the target object generates an action of approaching the touch display screen.

Wherein the target object may be a user's hand, ear, face, etc.

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

The number of the proximity sensors may be one or more, and is not limited herein.

The proximity sensor can be disposed 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 the like.

For example, assuming that the distance between the target object and the electronic device at the first time is 4cm, the first threshold is 2cm, and the distance between the target object and the electronic device at the second time is 2cm, the difference between the first distance and the second distance is equal to 2cm (equal to the first threshold), and it is determined that the target object has an action of approaching the touch display screen.

Currently, a common method for detecting whether an object has an action of approaching a touch display screen is as follows: whether the value received by the proximity sensor exceeds a preset threshold (such as 150 or 200) is detected, if so, the target object is determined to be in a proximity action, and if not, the target object is determined to be in a distance action, so that when the target object slightly shakes, the target object is also detected to be in the proximity action or the target object is determined to be in the distance action, and the detection precision is not accurate enough.

In the embodiment of the application, when the target object is already in a close state with the touch display screen (for example, when a user holds the electronic device to make a call, etc.), the electronic device determines whether the target object is in a close motion according to the variation of the distance, so that a slight variation can be eliminated, and the detection accuracy is improved.

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

and under the condition that the difference value of the first distance and the second distance is smaller than or equal to a second threshold value, the electronic equipment determines that the target object moves away from the touch display screen.

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

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

In one implementation of the present application, the electronic device starts a sensor proximity detection mode before step 201.

Further, the electronic device initiates a sensor proximity detection mode under a first condition, the first condition being at least one of: the electronic device is in a screen-off state, a touch display screen of the electronic device faces upwards, and the electronic device is in an Always On Display (AOD) mode.

Specifically, because proximity sensor sets up in touch-control display screen below, if use proximity sensor to approach and detect under electronic equipment is in the bright screen state and can lead to the splash screen phenomenon, consequently in this application, inject and be in the electronic equipment and just use proximity sensor to approach and detect under the state of putting out the screen, can avoid the splash screen phenomenon, promote display effect.

Specifically, the electronic device includes a gravity sensor including a gravity block and a plurality of piezoelectric crystals disposed on a peripheral side of the gravity block, the plurality of piezoelectric crystals being distributed on different sides of the gravity block, as shown in fig. 2B. In fig. 2B, the gravity sensor includes 1 gravity block and 6 piezoelectric crystals, where the 6 piezoelectric crystals respectively correspond to 6 surfaces of the electronic device, for example, the piezoelectric crystal 2 corresponds to a touch display screen of the electronic device, the piezoelectric crystal 3 corresponds to a rear shell of the electronic device, the piezoelectric crystal 1 corresponds to a left side surface of the electronic device, the piezoelectric crystal 6 corresponds to a right side surface of the electronic device, the piezoelectric crystal 5 corresponds to an upper side surface of the electronic device, and the piezoelectric crystal 4 corresponds to a lower side surface of the electronic device.

When the piezoelectric crystal 2 is pressed by the gravity block, the electric signal output by the piezoelectric crystal 2 is not 0, and at this time, the electronic device detects that the touch display screen of the electronic device faces downwards. When the piezoelectric crystal 3 is pressed by the gravity block, the electric signal output by the piezoelectric crystal 3 is not 0, and at this time, the electronic device detects that the touch display screen of the electronic device faces upwards.

Specifically, because proximity sensor sets up in touch-sensitive display screen below, when touch-sensitive display screen down (for example place electronic equipment's touch-sensitive display screen down at the desktop), if carry out proximity detection through proximity sensor, the result of detecting is in the state of being close always, but such detection does not have any meaning, can also lead to electronic equipment maloperation, and the problem of resource consumption, consequently in this application, prescribe to use proximity sensor to carry out proximity detection under the condition that electronic equipment's touch-sensitive display screen is up just, can avoid above-mentioned problem, promote electronic equipment's performance.

Specifically, the AOD mode is a display mode in which a specific display area of the touch display screen is kept normally bright in the screen lock state of the electronic device. In the AOD mode, information such as time, notification, and the like can be displayed in a specific display area. Referring to fig. 2C, fig. 2C is a schematic display diagram of an electronic device in an AOD mode according to an embodiment of the present disclosure. As shown in fig. 2C, the touch display screen includes a specific display area, the specific display area occupies a very small area of the entire touch display screen, the specific display area is used for displaying information such as time and notification messages, and since only the specific area is lit, the power consumption of the AOD mode can be very low, and for a user who is used to view the mobile phone, the touch display screen of the electronic device does not need to be frequently lit and the electronic device is unlocked, which is very convenient.

When the electronic equipment is in the AOD mode, the proximity sensor is arranged below the touch display screen except the specific display area.

In an implementation manner of the present application, the method further includes: and the electronic equipment is controlled according to the determined action of the target object.

In an implementation manner of the present application, an electronic device is in a screen-off state, and the electronic device controls the electronic device according to a determined motion of the target object, including: after the target object generates an action of approaching the touch display screen, the electronic equipment performs a screen lightening operation;

after the screen-lighting operation is completed, the method further comprises: the electronic device initiates a TP proximity detection mode.

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

The touch display screen comprises 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 for detecting whether the target object is close to the touch display screen or far from the touch display screen through the touch screen of the touch display screen.

Specifically, because proximity sensor sets up in touch-control display screen below, if use proximity sensor to approach and detect and can lead to the splash screen phenomenon under electronic equipment is in the bright screen state, consequently in this application, use TP to approach and detect under electronic equipment is in the bright screen state, can avoid the splash screen phenomenon, promote display effect.

Specifically, currently, when a user places a call by holding the electronic device, the proximity sensor detects a proximity state due to the electronic device being close to the ear, and in this case, the screen is turned off. If the distance between the electronic device and the ear slightly fluctuates due to environmental factors (such as a user sitting in a car and the car jolts) during a call, the proximity sensor detects a far-away state, and in this case, the touch screen is turned on, so that in some scenes, the touch screen is turned on and off.

And in this application, confirm whether target object is close to the touch-control display screen through the distance difference at two moments, can avoid electronic equipment and target object distance to appear slight change and lead to the state that the touch-control display screen is bright for a moment and puts out the screen for a moment like this, promoted detection accuracy.

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

the electronic equipment carries out TP proximity detection; and under the condition that the target object is detected to be far away from the touch display screen, the electronic equipment performs screen-off operation.

The TP proximity detection principle is as follows: the method comprises the steps that the electronic equipment obtains a preset area of a touch screen for approaching detection; the electronic equipment adjusts the driving voltage of the preset area so as to improve the effective detection distance of the preset area; the electronic equipment detects the capacity value data of the preset area; determining the distance between a target object and the touch display screen according to the capacity value data; and if the difference value of the distances determined before and after is smaller than or equal to a second threshold value, determining that the target object is far away from the touch display screen, and if the difference value of the distances determined before and after is larger than or equal to a first threshold value, determining that the target object is close to the touch display screen.

In general, since the touch screen is used to detect a touch operation of a user in a conventional state, a driving voltage is low, and in order to implement proximity detection, power needs to be increased to implement detection at a longer distance.

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

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

Or the preset area is the upper half screen of the touch screen; generally, when a user holds an electronic device for a call, the upper half screen of the electronic device contacts the face or the ear of the user.

Or the preset area is an area determined according to the content of the image collected by the camera. The electronic equipment can specifically acquire the current image content through the camera, and determine a preset area which can be contacted by a preset part of a user according to the current image content, the position relation between the camera and the touch screen and the position relation between the current image content and the face or the ear of the user.

Therefore, in the embodiment of the application, the electronic equipment can set the preset region in multiple modes, and the flexibility and the detection accuracy of the setting of the preset region are improved.

In specific implementation, the electronic device may increase the voltage value of the driving signal, for example, increase the voltage value to 3.3V from 2V, and the specific adjustment strategy may be preset based on the capability information of the touch screen control chip. Therefore, in the embodiment of the application, the electronic equipment can improve the detection power of the touch screen through boosting, so that the effective detection distance of the touch screen is increased, the approach detection is realized, and the accuracy and the success rate of the approach detection are improved.

The touch screen proximity detection principle is similar to the traditional capacitive touch screen detection principle, and specifically works by utilizing current induction of a human body. Due to the fact that a human body electric field, the skin of a user and each detection unit on the surface of the touch screen form a coupling capacitor, and the capacitance value data of the coupling capacitor changes along with the change of the distance between the skin of the user and the surface of the touch screen within a preset distance range, the electronic equipment can detect the distance by detecting the capacitance value data of each detection unit, and therefore approach detection is achieved.

It can be seen that, in this application embodiment, under the condition that proximity sensor locates the touch-control display screen below, use sensor proximity detection under the screen state of putting out, use TP proximity detection under the bright screen state, guarantee the display effect promptly, guaranteed proximity detection, further promoted electronic equipment's performance.

Further, the electronic device is currently in a call state, the electronic device performs a screen-up operation due to detection of a motion of a target object away from the touch display screen, and after the screen-up operation is completed, the electronic device starts a TP proximity detection mode, and the method further includes:

after the time length is set, if the target object is not detected to be close to the touch display screen, the conversation audio output by the electronic equipment has no conversation content, and the conversation audio collected by the electronic equipment has no conversation content, the electronic equipment hangs up the current conversation.

Wherein, the fact that the call audio has no call content means that the electronic device does not obtain any text information by analyzing the call audio. For example, the user currently talking does not speak, the audio collected by the electronic device is the environmental sound, or the user talking to the other party does not speak, and the audio collected by the electronic device of the other party is the environmental sound.

It can be seen that, in the embodiment of the 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 certain period of time, the target object is far away from the touch display screen, then both parties of the call do not speak again, at this time, it may be that both parties have already finished the call but both parties forget to hang up the call.

In an implementation manner of the present application, an electronic device is currently in an audio output state, and the electronic device controls the electronic device according to the determined motion of the target object, including: after the target object generates an action of approaching the touch display screen, the electronic equipment reduces the output volume of the audio; after the target object moves away from the touch display screen, the electronic equipment increases the output volume of the audio.

In a specific implementation, the volume of the audio output can be adjusted to be lower or higher according to the difference between the first distance and the second distance, and the smaller the difference is, the smaller the amplitude of the adjustment is, the larger the difference is, the larger the amplitude of the adjustment is.

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

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

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

In the mapping relationship between the numerical values and the distances, the larger the numerical value is, the smaller the corresponding distance is, and the smaller the numerical value is, the larger the corresponding distance is. The mapping relationship between the numerical value and the distance is shown in table 1. The values in table 1 and the corresponding distances were obtained experimentally. The specific method of the experiment comprises the following steps: the average value (for example, 100) received by the electronic device is measured by the machine 1 when the standard shielding object is placed at a position 4cm away from the screen, the average value (for example, 120) received by the electronic device is measured by the machine 2, the average value (for example, 130) received by the electronic device is measured by the machine 3, and the like, and finally, the average value is calculated based on the average values measured by the machines, so that the value corresponding to the distance of 4cm in the table 1 is obtained. The experimental methods at distances of 1cm, 2cm, 3cm, 5cm, 6cm, etc. from the screen are the same as those at distances of 4cm from the screen, and will not be described here.

Numerical value	Distance between two adjacent plates
		330	1cm
230	2cm
		165	3cm

……	……

Therefore, in the embodiment of the application, a standard mapping relation obtained by an experiment is imported into the electronic equipment in advance, and the subsequent electronic equipment can determine the distance through the mapping relation, so that the operation is simple, and the distance detection through the proximity sensor is realized.

Referring to fig. 3, fig. 3 is a schematic flowchart of a proximity detection method according to an embodiment of the present application, applied to the electronic device, where the proximity detection method includes:

step 301: at a first time, the electronic device obtains a first value through the proximity sensor.

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

Step 303: at a second time, the electronic device obtains a second value through the proximity sensor.

Step 304: and the electronic equipment determines a second distance between the target object corresponding to the second numerical value and the touch display screen according to the mapping relation between the numerical value and the distance.

Step 305: and under the condition that the difference value of the first distance and the second distance is larger than or equal to a first threshold value, the electronic equipment determines that the target object generates an action of approaching the touch display screen. After step 305 is executed, step 307 is executed.

Step 306: and under the condition that the difference value of the first distance and the second distance is smaller than or equal to a second threshold value, the electronic equipment determines that the target object moves away from the touch display screen. If the electronic device is currently in the call state, step 307 is executed after step 306 is executed.
