In the related art, the pressure-sensitive module regards the heat source of the entire electronic device as a whole, and performs temperature compensation on the influence of the whole heat source. However, in an actual use scenario, the heat source of the electronic device is not single, and the influence on the pressure-sensitive modules at different positions is different. Therefore, even if the pressure-sensitive module having the temperature compensation function is used, the pressing accuracy of the pressure-sensitive module is not accurate due to the temperature difference, and problems such as delayed release and false triggering still exist.

The execution main body of the pressure control method of the sub-equipment provided by the embodiment of the application is a pressure control device of the electronic equipment with the pressure module. The device may be an electronic device, or may also be a control module or other functional modules in the electronic device, where the control module or other functional modules are used to execute the pressure-sensitive control method, and this is not limited in this embodiment of the application.
The following description, with reference to the accompanying drawings, provides a method, an apparatus, an electronic device, and a medium for controlling pressure of an electronic device according to embodiments of the present application through specific embodiments and application scenarios thereof. The detailed description is given. The method will be described below by taking as an example a pressure-sensitive control device in which the execution body is an electronic apparatus.
As shown, an embodiment of the present application provides a pressure control method for an electronic device, as shown in fig. 1, the electronic device includes a screen and at least one pressure module disposed under the screen, as shown in fig. 4, the method may include steps 101 to 104 described below.
Step 101, receiving the pressing input of the screen by the user.
And 102, responding to the pressing input, acquiring a preset temperature coefficient of a pressing area corresponding to the pressing input, and acquiring a pressure sensing signal through a target pressure sensing module corresponding to the pressing area.
And 103, correcting the pressure-sensitive signal according to a preset temperature coefficient.
And 104, executing a function corresponding to the press input according to the corrected pressure sensing signal.
The screen comprises N areas, wherein N is a positive integer, and each area corresponds to a preset temperature coefficient; the pressing area is at least one of the N areas; the target pressure sensing module is one or more of the at least one pressure sensing module.
In the embodiment of the application, a processing unit is further arranged below the screen of the electronic device and comprises a circuit board, a pressure detection circuit and a display module are arranged on the circuit board, and the display module corresponds to the screen. As shown in fig. 1, the pressure sensing module includes: a support plate (e.g., a steel plate) based on a first Wheatstone bridge of deformation resistance. Wherein, the supporting plate may be parallel to the display module, and the supporting plate includes a first supporting portion 31 and a second supporting portion 32 disposed at an interval.
In one example, with respect to the first wheatstone bridge:
1) the pressure detection circuit is electrically connected with the first output end of the first Wheatstone bridge.
2) The first Wheatstone bridge comprises a first circuit and a second circuit connected in parallel, wherein the first circuit comprises two resistors R1 and R4 connected in series. The second circuit comprises two resistors R2 and R3 in series. Wherein at least part of R1, R2, R3 and R4 is a deformation resistor.
For example, as shown in fig. 1, R1 and R2 are disposed on a first side of the supporting plate, where the first side is a side of the supporting plate facing the display module; the R3 and R4 are arranged on the second side face of the supporting plate, and the second side face is the side face of the supporting plate back to the display module; meanwhile, R1, R2, R3 and R4 are bridged between the first supporting part and the second supporting part, so that R1, R2, R3 and R4 are all in a suspended state.

It can be understood that, when the pressure sensing module is pressed by a user, the shape of the deformation resistor changes, and then the resistance value of the deformation resistor changes. And the deformation quantity of the deformation resistor and the resistance value variation quantity of the deformation resistor have a corresponding relation. When a fixed voltage is provided to the first wheatstone bridge, the pressure detection circuit may detect a variation of a divided voltage of each resistor in the first wheatstone bridge, and the storage module of the circuit board may store in advance a correspondence between a magnitude of the pressure received by the pressure sensing module and a variation of the divided voltage of each resistor in the first wheatstone bridge.
Wherein, the pressure signal of pressure module includes: the voltage division signal of each resistor in the first Wheatstone bridge of the pressure sensing module (namely, the voltage division change condition of each resistor) is the pressure signal corresponding to the voltage division signal.
Therefore, when the pressure sensing module is pressed by a user, the pressure detection circuit can determine the pressure applied to the pressure sensing module according to the partial pressure change condition of each resistor in the first Wheatstone bridge and the corresponding relation between the pressure received by the pressure sensing module and the partial pressure change condition of each resistor in the first Wheatstone bridge. That is, the pressure-sensitive control device of the electronic device can acquire the pressure-sensitive signal of the first wheatstone bridge of the target pressure-sensitive module by the target pressure-sensitive module.
In this embodiment of the application, the N regions in the screen may be any regions in the screen, and the N regions may be preset regions.
It should be noted that the N regions may be distributed on the screen in an array or in other forms, and may be set according to specific requirements, which is not limited in this embodiment of the application.
Example 1, as shown in fig. 5, a screen of an electronic device is divided into 15 regions, the 15 regions are distributed on the screen in an array, dotted lines on the screen are only used for showing the respective regions, and in an actual scene, the dotted lines may not be displayed.
In an embodiment of the present application, the screen may include a flexible screen. In one example, some of the screens may be flexible screens, and the remaining screens may be rigid screens. Thus, the N regions may be located in a flexible screen region of the screen, that is, the screen regions corresponding to the N regions may be: a deformable region.
In the embodiment of the present application, each of the N regions corresponds to at least one function. In one example, different regions may correspond to different functions. For example, screen capture, turning on a camera, adjusting the volume of an electronic device, turning on a flashlight, etc.
Optionally, in this embodiment of the present application, each region corresponds to a predetermined temperature coefficient. In one example, different regions may correspond to different predetermined temperature coefficients, or multiple regions may correspond to the same predetermined temperature coefficient.
Optionally, in this embodiment of the application, the predetermined temperature coefficient may be preset, or may be set in real time based on an actual application scenario.
In this application embodiment, the pressure-sensitive signal that the target pressure-sensitive module that corresponds through the pressing zone obtained can be: and the pressure sensing signal of the target pressure sensing module corresponding to the pressing area.
In addition, according to the present invention, after the pressure sensing signal of the target pressure sensing module corresponding to the pressing area is corrected according to the acquired predetermined temperature coefficient, the corrected pressure sensing signal can be ensured to be the pressure sensing signal under the same temperature condition, and thus, the pressing accuracy of the target pressure sensing module is ensured.
It can be understood that the target pressure sensing module corresponding to the pressing area is: the pressure sensing module receives the pressing force of the user pressing input in the at least one pressure sensing module, or the pressure sensing module receives the pressing force of the user pressing input in the at least one pressure sensing module and is larger than or equal to a preset threshold value.
In the embodiment of the present application, the pressing area is an area that receives a user press in N areas.
In this embodiment of the application, in the case that a press input of a user is received, after the N regions are polled, a press region corresponding to the press input is determined, and then a predetermined temperature coefficient corresponding to the press region is determined.
Optionally, in this embodiment of the application, each region may correspond to one pressure-sensing module, or may correspond to a plurality of pressure-sensing modules. The embodiments of the present application do not limit this. That is, the number of the target pressure sensing modules corresponding to the pressing area is at least one.
It can be understood that the pressure sensing area (i.e. the pressure sensing area) of at least one pressure sensing module can cover N areas, so as to ensure that when a user performs a pressing input on any one or more of the N areas, the corresponding pressure sensing module can be triggered to detect the pressure sensing signal.
It should be noted that the pressure-sensitive signal obtained by the target pressure-sensitive module is: the detection result of the pressure detection circuit (for example, the pressure magnitude received by the pressure sensing module determined by the pressure detection circuit).
Therefore, the embodiment of the application can acquire the preset temperature coefficient of the pressing area corresponding to the pressing input, acquire the pressure sensing signal through the target pressure sensing module corresponding to the pressing area, and then correct the pressure sensing signal according to the preset temperature coefficient, so that the corrected pressure sensing signal is the pressure sensing signal under the same temperature condition. The accuracy of the pressure detection result is further improved. In addition, because the temperature coefficient of the pressing area is the preset temperature coefficient, the embodiment of the application can realize pressure control more accurately on the premise of ensuring efficiency and saving power consumption.
It is understood that the pressure-sensitive control device of the electronic device may execute the function corresponding to the press input according to the corrected pressure-sensitive signal of the target pressure-sensitive module (i.e., the pressure-sensitive signal of the target pressure-sensitive module corrected based on the predetermined temperature coefficient).
That is, the pressure-sensitive control device of the electronic apparatus can accurately execute the function corresponding to the press input, that is, the function corresponding to the press area corresponding to the press input, in accordance with the corrected pressure-sensitive signal.
Example 3, with reference to example 2, if the user presses the area 33 of the 15 areas of the electronic device, i.e. the area located at the upper left corner in fig. 5, if the area 33 corresponds to the function: the camera is turned on. When there is a temperature difference between the front and back of the electronic device, when the user wants to use the camera, the area 33 corresponding to the camera is pressed for input, and then the pressure control device of the electronic device can correct the pressure signal of the first pressure sensing module corresponding to the area 33 based on the predetermined temperature coefficient corresponding to the area 33, so as to ensure that the corrected first pressure sensing signal is the pressure sensing signal under the same temperature condition, and when the corrected pressure sensing signal meets the camera turn-on condition, the camera is turned on accurately. So, guaranteed the press precision of first pressure die set, avoided postponing release scheduling problem, satisfied user's demand.
According to the pressure control method of the electronic device, after the press input of the user to the screen is received, the preset temperature coefficient of the press area corresponding to the press input is obtained, the pressure signal is obtained through the target pressure module corresponding to the press area, the pressure signal of the target pressure module corresponding to the press area is corrected according to the preset temperature coefficient, the corrected pressure signal is ensured to be the pressure signal under the same temperature condition, and the function corresponding to the press input is executed according to the corrected pressure signal. Therefore, the pressure control device of the electronic equipment can accurately correct the pressure signals of the target pressure sensing module corresponding to the pressing area, the pressing precision of the target pressure sensing module is ensured, the problems of delayed release, false triggering and the like are avoided, and the temperature coefficient of the pressing area is the preset temperature coefficient, so that the power consumption of the electronic equipment is saved while the pressure signals of the target pressure sensing module corresponding to the pressing area are accurately corrected.
Optionally, in this embodiment of the present application, the predetermined temperature coefficient is positively correlated with the operating temperature of the region.
It is understood that the higher the operating temperature of the region corresponding to the predetermined temperature coefficient is, the larger the predetermined temperature coefficient is, and the lower the operating temperature of the corresponding region is, the smaller the predetermined temperature coefficient is.
That is, the predetermined temperature coefficient corresponding to the pressing area where the pressing input is received is positively correlated with the operating temperature of the pressing area.
Optionally, in this embodiment of the application, the predetermined temperature coefficient may be determined in real time based on each heat generating device in the electronic device corresponding to the screen. That is, the operating temperature of the region corresponding to the predetermined temperature coefficient is: and determining in real time according to each heating device in the area corresponding to the preset temperature coefficient.
Further optionally, in this embodiment of the application, the predetermined temperature coefficient corresponding to each of the N regions is: is determined based on the temperatures of all heat generating devices under the screen and the heat generating devices in the corresponding areas. That is, the operating temperature of the region corresponding to the predetermined temperature coefficient is: according to the temperatures of all the heating devices under the screen and all the heating devices in the area corresponding to the preset temperature coefficient.
For example, if the area B is the corresponding heat generating device, the camera module and the battery, when the user presses the area B, the predetermined temperature coefficient corresponding to the area B may be determined based on the temperatures of all the heat generating devices under the screen and the camera module and the battery. That is, the predetermined temperature coefficient corresponding to the region B is positively correlated with the temperatures of all the heat generating devices under the screen, the camera module and the battery.
It is understood that all heat generating devices under the screen are: all heating devices are arranged in the electronic equipment corresponding to the screen. The heating device under the corresponding area of each area is: and the heat generating device of the internal area of the electronic equipment corresponds to each area.
It can be understood that, because various electrical components are arranged at different positions inside the electronic device, the electrical components may generate heat during operation, and the heat generation amount of the electrical components at different positions inside the electronic device is different. Based on this, the predetermined temperature coefficient corresponding to each area is related to the heat generating device (i.e., the electrical component generating heat) corresponding to the position of the respective area in the electronic device, that is, the predetermined temperature coefficient corresponding to each area is positively related to the operating temperature corresponding to the position of the respective area in the electronic device.
Further optionally, in this embodiment of the application, the predetermined temperature coefficient corresponding to each region may also be determined based on a preset temperature detection element.
The preset temperature detection element may be a temperature detection element in the electronic device.
It can be understood that, when a user needs to turn on a function corresponding to a certain area, as long as the area is selected, the predetermined temperature coefficient corresponding to the area can be determined according to the preset temperature detection element.
For example, if the temperature detection elements preset in the area B are the camera module and the battery, when the user presses the area B, the predetermined temperature coefficient corresponding to the area B may be determined based on the temperatures of the camera module and the battery.
Optionally, in this embodiment of the application, "acquiring a predetermined temperature coefficient of a pressing area corresponding to the pressing input, and acquiring a pressure sensing signal through a target pressure sensing module corresponding to the pressing area" in step 102 includes steps 102a to 102 c.
And 102a, determining a position signal corresponding to a pressing area of the pressing input.
It will be appreciated that the location signal will be different for different areas receiving the press input. Namely: different pressing areas correspond to different position signals.
And 102b, acquiring a preset temperature coefficient of a pressing area corresponding to the pressing input according to the position signal.
Since the position signal corresponds to the pressing area that receives the pressing input, the predetermined temperature coefficient of the pressing area corresponding to the pressing input can be acquired from the position signal.
And 102c, acquiring a pressure sensing signal of the target pressure sensing module through the position signal.
The pressure-sensitive signal comprises a pressure signal of the target pressure-sensitive module.
The target pressure sensing module is as follows: and the pressure sensing module corresponds to the position signal corresponding to the pressing area.
In this application embodiment, the pressure signal of target pressure module is obtained through position signal, indicates: and acquiring a pressure sensing signal of the target pressure sensing module through the target pressure sensing module corresponding to the pressing area.
It can be understood that the pressure signal of the target pressure sensing module is the pressure signal of the first wheatstone bridge corresponding to the target pressure sensing module. When the pressing area receives pressing input of a user, the pressure detection circuit can determine the pressure signal of the target pressure sensing module according to the partial pressure change condition of each resistor in the first Wheatstone bridge in the target pressure sensing module and the corresponding relation between the pressure received by the target pressure sensing module and the partial pressure change condition of each resistor in the first Wheatstone bridge in the target pressure sensing module, and further can acquire the pressure signal of the target pressure sensing module.
Therefore, the pressure-sensitive signal including the pressure signal may be corrected according to a predetermined temperature coefficient of the pressing area corresponding to the pressing input, so that the corrected pressure-sensitive signal is a pressure-sensitive signal under the same temperature condition. The accuracy of the pressure detection result is further improved.
Optionally, in this embodiment of the application, the pressure-sensitive module includes a temperature detection unit, the temperature detection unit is based on a wheatstone bridge, and the temperature detection unit includes at least one deformation resistor. After step 102a, the method further includes step 102a 1.
Step 102a1, acquiring a temperature signal detected by the temperature detection unit of the target pressure sensing module corresponding to the pressing area according to the position signal.
The above step 103 includes a step 103 a.
And 103a, correcting the pressure-sensitive signal according to the preset temperature coefficient and the temperature signal.
In an embodiment of the present application, the temperature detecting unit includes a temperature detecting circuit and a second wheatstone bridge.
In one example, as shown in FIG. 1, with respect to the second Wheatstone bridge:
1) the temperature detection circuit is electrically connected with the second output end of the second Wheatstone bridge so as to detect the temperature difference between the first side surface and the second side surface.
2) The second wheatstone bridge comprises a third circuit and a fourth circuit connected in parallel, the third circuit comprising two resistors r1 and r4 connected in series. The second circuit comprises two resistors r2 and r3 in series. Wherein at least one of r1, r2, r3 and r4 is the deformation resistor.
Illustratively, referring to fig. 1, r1 and r3 are located on opposite sides (i.e., first and second sides) of the first support, and r2 and r4 are located on opposite sides (i.e., first and second sides) of the second support, respectively.
Further, as shown in fig. 3, the second output terminals include a sub-output terminal C (i.e., ANN in fig. 3) between r1 and r4, and a sub-output terminal D (i.e., ANP in fig. 3) between r2 and r 3.
It will be appreciated that in the case where a fixed voltage is supplied to the second wheatstone bridge, when the resistance of either the third circuit or the fourth circuit changes, the voltage division of the resistors in the third circuit or the fourth circuit will change accordingly. Therefore, the correspondence relationship between the temperature difference between the first side surface and the second side surface and the voltage difference between the sub-output end C and the sub-output end D can be pre-stored in the storage module of the above circuit board, so that the temperature detection circuit can determine the magnitude of the temperature difference between the first side surface and the second side surface according to the voltage difference between the sub-output end C and the sub-output end D, wherein the temperature signal detected by the temperature detection unit is: a temperature signal corresponding to a temperature difference between the first side and the second side.
Furthermore, the pressure-sensitive control device of the electronic device may acquire the temperature signal detected by the temperature detection unit of the target pressure-sensitive module according to the position signal corresponding to the pressing area.
It should be noted that the deformation resistor in the second wheatstone bridge and the deformation resistor in the first wheatstone bridge may be deformation resistors made of the same material.
Regarding the correction of the pressure-sensitive signal:
in the embodiment of the present application, the second wheatstone bridge may be used for temperature compensation of the first wheatstone bridge.
In this embodiment, the pressure-sensitive signal (for example, the pressure-sensitive signal including the pressure signal) may be corrected according to the temperature signal to obtain a first correction parameter, and then the first correction parameter may be corrected according to a predetermined temperature coefficient. Therefore, the problem that temperature compensation cannot be accurately carried out due to the fact that the heat source of the whole electronic equipment is regarded as a whole is solved. The temperature difference between the first side surface and the second side surface is further reduced, the accuracy of temperature compensation is improved, and the pressing precision of the first Wheatstone bridge is improved.
The following describes how to modify the pressure-sensitive signal according to the temperature signal, taking the pressure-sensitive signal as an example.
In one example, with respect to the relationship of the second wheatstone bridge to the first wheatstone bridge:
since the resistance of the resistor generally varies with temperature, the resistance of the same resistor generally varies at different temperatures. Because various electrical components inside the electronic device may generate heat during the working process, a temperature difference may exist between the first side surface and the second side surface of the supporting plate, and the temperature difference may cause the resistance value of the deformation resistor to change, thereby causing an error in the voltage difference between the sub-output end a and the sub-output end B, and further causing an inaccurate pressure detection result.
Based on this, the circuit board may correct the detection result of the pressure detection circuit according to the detection result of the temperature detection circuit (i.e., the temperature difference between the first side surface and the second side surface, for example, the temperature signal detected by the temperature detection unit of the target pressure sensing module corresponding to the position signal), so as to obtain a corrected pressure sensing signal.
Illustratively, the temperature of the first side surface is taken as a reference temperature, and the correspondence between the temperature difference and the resistance change amount may be determined in advance. Accordingly, when the temperatures of the second side and the first side are different, it is possible to determine the amount of resistance change due to the temperature difference based on the temperature difference between the first side and the second side, and to compensate for R3 and R4 located at the second side by the amount of resistance change.
For example, when the resistance value of the deformation resistor of the second side surface is larger than the resistance value of the deformation resistor of the first side surface by M due to the temperature difference between the first side surface and the second side surface, if the current resistance value of R3 is M1 and the current resistance value of R4 is M2, after the correction, the current resistance value of R3 is (M1-M) and the current resistance value of R4 is (M2-M).
Therefore, the detection result of the pressure detection circuit can be corrected according to the detection result of the temperature detection circuit, and the problem that the pressure detection result is inaccurate due to the temperature difference between the first side surface and the second side surface is solved.
The following describes how to modify the first modification parameter according to the predetermined temperature coefficient.
In this embodiment, the predetermined temperature coefficient may be multiplied by the first correction parameter to obtain the second correction parameter. The second correction parameter is: and correcting the correction parameter obtained after the pressure-sensitive signal according to the preset temperature coefficient and the temperature signal.
For example, if the predetermined temperature coefficient is f, the first correction parameter is d, and the second correction parameter is m, then m is f × d. It can be understood that the second correction parameter m is equivalent to the pressure-sensitive parameter acquired by each deformation resistor of the first wheatstone bridge in the target pressure-sensitive module under the same temperature adjustment, so that the pressure-sensitive parameter output by the target pressure-sensitive module corresponding to the pressing area can be corrected quickly and accurately in the embodiment of the application, and the pressing precision of the target pressure-sensitive module is ensured.
Optionally, in this embodiment of the present application, the step 103 includes a step 103 b.
And 103b, correcting the pressure-sensitive signal according to the preset temperature coefficient and the current temperature of the electronic equipment corresponding to the screen.
It should be noted that the current temperature of the electronic device may be a complete machine temperature of the electronic device, and the complete machine temperature is usually greatly affected by an external environment. Based on this, the present embodiment of the application has compromise predetermined temperature coefficient and the influence of the current temperature of electronic equipment to target pressure and feels module testing result for the correction result is more accurate.
Optionally, in this embodiment of the application, the temperature detecting unit includes a thermistor, and the thermistor is disposed at a heat generating device in the electronic device corresponding to the pressing area.
It is understood that at least one of r1, r2, r3 and r4 in the second wheatstone bridge is the thermistor.
In the related art, a temperature detecting element (e.g., a thermistor) is usually disposed near a heat generating device inside an electronic apparatus to detect the temperature of the corresponding heat generating device. For example, in electronic equipment, a temperature detection element is usually disposed near a heat generating device such as a main board, a battery, a camera module, or a sub-board interface. Therefore, the temperature detected by the temperature detection element arranged near each heating device of the electronic equipment can be directly multiplexed through the second Wheatstone bridge, extra cost is not required to be added, or a redundant structure is not required to be designed to be stacked, the temperature of the heating device under the corresponding area of each area is obtained, and the installation space in the electronic equipment is saved.
Optionally, in this embodiment of the application, the step 102a1 includes steps a to D.
And step A, determining a target temperature detection unit of the target pressure sensing module corresponding to the pressing area according to the position signal.
And B, detecting the deformation amount corresponding to the target temperature detection unit.
And step C, outputting a corresponding first voltage signal according to the deformation quantity.
And D, acquiring a temperature signal corresponding to the first voltage signal.
It can be understood that different position signals correspond to different temperature detection units, and the pressure control device of the electronic device can determine the target temperature detection unit of the target pressure module corresponding to the pressing area according to the position signal corresponding to the pressing area.
It can be understood that, since the temperature detection unit includes at least one deformation resistor, when the screen receives a press input from a user, the pressure-sensitive control device of the electronic device can detect a deformation amount corresponding to the target temperature detection unit, and output a corresponding first voltage signal according to the deformation amount, and then can acquire a temperature signal corresponding to the first voltage signal. Further, a temperature signal corresponding to the target temperature detection means can be acquired.
It is understood that the first voltage signal is a first voltage signal of the target temperature detection unit. The first voltage signal of the target temperature detection unit is: a voltage difference between the sub-output terminal C and the sub-output terminal D of the target temperature detecting unit.
For example, when the electronic device receives a press input, the pressure-sensitive control device of the electronic device may detect a voltage difference between the sub-output terminal C and the sub-output terminal D of the target temperature detection unit. Therefore, the pressure control device of the electronic equipment can acquire the temperature signal corresponding to the target temperature detection unit through the corresponding relation stored in the storage module of the circuit board. The corresponding relationship is as follows: the temperature difference between the first side surface and the second side surface and the voltage difference between the sub-output end C and the sub-output end D.
Optionally, in this embodiment of the application, the sensing area corresponding to the pressing input includes at least two areas; illustratively, before "acquiring the predetermined temperature coefficient of the pressing area corresponding to the pressing input and acquiring the pressure sensing signal by the target pressure sensing module corresponding to the pressing area" in the step 102, the step 101a is included.
And step 101a, taking a target area in the at least two areas as a pressing area corresponding to the pressing input.
The pressure sensing parameter corresponding to the pressure sensing signal of the pressure sensing module corresponding to the target area is greater than or equal to the first threshold value. The pressure-sensitive parameters may be: a pressure parameter or a voltage parameter.
Illustratively, the pressure parameters are: and the parameters corresponding to the pressure signals of the first Wheatstone bridges of the pressure sensing module corresponding to the target area. The voltage parameters are: and the parameters correspond to the voltage signals of the first Wheatstone bridges of the pressure sensing module corresponding to the target area. Wherein, the voltage signal of the first Wheatstone bridge is: the voltage division signals of the resistors in the first Wheatstone bridge.
Illustratively, the sensing regions corresponding to the press input are: the region of the pressure-sensitive reaction can be triggered by the pressing force.
It can be understood that, since the pressure sensing module generally includes the deformable supporting portion, when a user performs a pressing input on a target area of the N areas, under the action of the pressing force, in addition to triggering the target pressure sensing module corresponding to the target area to output a pressure sensing signal, other pressure sensing modules corresponding to other areas close to the target area to output a pressure sensing signal are also triggered. Wherein the target area and the other areas are the sensing areas. In this case, the pressure-sensitive parameter corresponding to the pressure-sensitive signal output by the target pressure-sensitive module corresponding to the target area is generally larger than the pressure-sensitive parameter corresponding to the pressure-sensitive signal output by the other pressure-sensitive module corresponding to the other area.
Based on this, in the embodiment of the present application, the area in which the pressure-sensitive parameter corresponding to the pressure-sensitive signal output by the corresponding pressure-sensitive module in the at least two areas is greater than or equal to the first threshold is taken as the target area. Therefore, the pressing areas corresponding to the pressing input can be accurately determined in the plurality of sensing areas, so that the functions corresponding to the pressing input can be accurately executed, and meanwhile, the respective pressure-sensitive parameters are not corrected based on the preset temperature coefficients corresponding to all the sensing areas, so that the corresponding functions can be accurately executed, and meanwhile, the power consumption of the electronic equipment is avoided being saved.
For example, the pressure-sensitive parameter corresponding to the pressure-sensitive signal output by the pressure-sensitive module corresponding to the sensing area may be: and the parameter is obtained by correcting the detection result of the pressure detection circuit according to the detection result of the temperature detection circuit.
Example 3, the N regions include a region 1, a region 2, a region 3, a region 4, a region 5, and a region 6, and if the user wants to use a function corresponding to the region 1 of the N regions, when the user performs a pressing input on the region 1, the pressure sensing modules corresponding to the regions 1, 2, and 3 respectively output pressure sensing parameters corresponding to the pressure sensing signals under the action of a pressing force: a. b and c, wherein a is greater than the first threshold, and b and c are less than the first threshold, the pressure-sensitive control device of the electronic device takes the area 1 as a pressing area corresponding to the pressing input, so that the pressure-sensitive control device of the electronic device can accurately execute a function corresponding to the pressing input, that is, execute the function corresponding to the area 1 to meet the user requirement.
Optionally, in this embodiment of the application, the sensing area is: among the N regions, the region corresponding to the pressure sensing module with the pressure sensing parameter greater than 0 corresponding to the output pressure sensing signal, or the sensing region is: and in the N areas, the area corresponding to the pressure sensing module with the pressure sensing parameter corresponding to the output pressure sensing signal larger than the second threshold value.
Wherein the second threshold is greater than 0 and is less than the first threshold.
Generally, the farther away from the area of the pressing input position, the smaller the pressure-sensitive parameter corresponding to the pressure-sensitive signal output by the pressure-sensitive module is, the closer to the area of the pressing input position, the larger the pressure-sensitive parameter corresponding to the pressure-sensitive signal output by the pressure-sensitive module is, and therefore, the area in which the corresponding pressure-sensitive parameter is greater than the second threshold needs to be screened out from the sensing area, so that the target area can be determined quickly, and the power consumption of the electronic device can be saved.
