It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The pressure-sensitive signal processing method provided by the embodiment of the application can be applied to a scene of detecting the pressure applied to a screen.
The pressure-sensitive signal processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, a pressure-sensitive signal processing method provided in an embodiment of the present application may be executed by an electronic device, where the electronic device includes a screen and a pressure-sensitive module. The pressure sensing module is arranged on at least one of the first side and the second side of the screen, the first side and the second side are distributed oppositely, and the first side is the side where the display surface of the screen is located.
For example, the pressure sensing module may be a transparent module, and the pressure sensing module is disposed between the glass cover plate and the screen, i.e., the first side; the module can also be arranged below the screen, namely the second side.
The method may comprise the following steps 201 to 203:
For example, the first pressure-sensitive signal may be an electrical signal output by the pressure-sensitive module after the screen is subjected to a pressure, and the electrical signal may be at least one of a current, a voltage, a capacitance, an inductance, or an electromagnetic field strength.
Exemplarily, the present application provides an optional pressure sensing module as shown in fig. 2, a scheme of setting the pressure sensing module at a center position of a screen of an electronic device is provided, when a user applies pressure to the screen, a screen area to which the pressure is applied generates micro deformation, and then a resistance value of a pressure sensing resistor in the pressure sensing module is driven to change, at this time, the pressure sensing module outputs current, the electronic device can determine whether the screen is under the pressure by detecting whether the pressure sensing module outputs the current, and determine a stress magnitude of the screen by detecting a magnitude of the current output by the pressure sensing module. However, the current design has a certain technical defect, and because the edge of the screen is far away from the pressure sensing module, the deformation of the pressure sensing resistor in the pressure sensing module caused by the pressure applied to the edge of the screen is small, so that the pressure sensing signal generated by the pressure sensing resistor is weak, and the sensitivity of the screen for detecting the pressure applied to the edge of the screen is low.
Exemplarily, the pressure sensing module includes a first deformation member, a second deformation member and a support member, and the first deformation member, the support member and the second deformation member are sequentially stacked in a direction perpendicular to the screen. The first deformation piece and the second deformation piece are deformation resistors in the pressure sensing module.
It should be noted that the pressure sensing module in the embodiment of the present application may be a pressure sensing module made of a piezoelectric material, or a pressure sensing module made of a magnet and a hall detection element, and the like, which is not limited in the embodiment of the present application.
In an alternative embodiment of the present application, the pressure sensing module is a pressure sensing module having a wheatstone bridge structure, as shown in fig. 3, which is a wheatstone bridge device composed of 4 resistors for measuring the resistance of one of the resistors (the resistance of the other 3 resistors is known). 4 resistors (R1, R2, R3 and R4 respectively) form a squareOne end of the current meter G is connected with two opposite connectors, and the other end of the current meter G is connected with the other two opposite connectors. When the current meter indicates no current flow, the bridge is in equilibrium, i.e. Gi0, R1R 2R 3R 4. As shown in fig. 4, since the printed resistor is used to detect the pressure value inside the pressure sensing module, and the attached screen is placed below the screen, when the screen is pressed by the external pressure F, the upper deformation resistor a is extruded, and the lower deformation resistor b is stretched, at this time, the resistance value of the pressure sensing resistor changes, which results in GiNo longer 0. According to this principle, G can be detectediTo determine the amount of pressure the screen is subjected to. The deformation resistance may be a deformation resistance a and a deformation resistance b as shown in fig. 4.
It should be noted that, the electronic device can improve the pressing sensitivity of the screen edge by increasing the number of the pressure modules, but this way not only increases the material cost, but also increases the power consumption of the electronic device, which is not an ideal solution. In the related art, the design of the pressure sensing module may be better than that of the pressure sensing module in the embodiment of the present application, and if other types of pressure sensing modules also have the technical problems related to the present application, the technical solutions of the present application can also be adopted to solve the problems.
The target multiple is less than or equal to a first preset multiple, and the first preset multiple is a ratio between a maximum output value of the second pressure-sensitive signal and a maximum output value of the first pressure-sensitive signal.
For example, after acquiring a first pressure-sensitive signal collected by the pressure-sensitive module, the pressure-sensitive signal processing device transmits the first pressure-sensitive signal to a Micro Controller Unit (MCU), and the MCU amplifies the first pressure-sensitive signal by a target multiple and transmits an obtained second pressure-sensitive signal to an application chip (AP). Then, the pressure-sensitive signal processing device executes an operation corresponding to the second pressure-sensitive signal, i.e., the preset operation, according to a preset instruction of the electronic device or a user. Specifically, the operation may be a popup attribute menu, a screen saver, or setting an icon to a movable state, or the like.
For example, the maximum output value of the second pressure-sensitive signal may be a maximum threshold of the output signal of the pressure-sensitive module.
Illustratively, the target multiple may be smaller than a predetermined multiple. The predetermined multiple is: when the target area of the screen is pressed by a pressing force degree less than or equal to the preset pressure, the signal intensity of the second pressure-sensitive signal can satisfy the maximum multiple of the preset condition.
For example, in a normal situation, the electronic device may detect the pressure applied to the screen within a certain range, and when the pressure applied to the screen exceeds the maximum detection value, the strength of the pressure-sensitive signal reaches the maximum value and is not increased any more, and at this time, the pressure-sensitive module is in an output saturation state. The target multiple is: when the pressure applied to the screen is equal to the preset pressure, the signal intensity of the second pressure-sensitive signal is just the maximum value which can be identified by the electronic equipment.
For example, since there may be differences in the number and positions of the pressure sensing modules disposed on different electronic devices, some of the pressure sensing modules of the electronic devices may be disposed at the center of the screen, and some of the pressure sensing modules of the electronic devices may be disposed in the center areas of the upper and lower portions of the screen, the target area is: the central area of the screen, or the area where the pressure sensing module is located.
Therefore, under the condition that the screen is pressed, the first pressure-sensitive signals are collected through the pressure-sensitive module, then the second pressure-sensitive signals are obtained after the first pressure-sensitive signals are amplified by the target multiple, the pressure-sensitive signals generated in the edge area of the screen can be amplified, and the sensitivity of the electronic equipment to the pressing operation response of the user for pressing the edge of the screen is improved.
Optionally, in this embodiment of the application, in the case of increasing the intensity of the pressure-sensitive signal generated when the edge of the screen is pressed, in order to avoid that the signal intensity of the pressure-sensitive signal generated when the user presses the target area reaches the identification critical value of the pressure-sensitive signal processing device too early, the pressure-sensitive signal processing device may amplify the generated pressure-sensitive signal by different factors according to the pressed position of the screen.
For example, before the step 202, the pressure-sensitive signal processing method provided in the embodiment of the present application may further include the following steps 204a1 and 204a 2:
in step 204a1, the pressure-sensitive signal processing means determines the pressed position through the screen.
Step 204a2, the pressure signal processing device determines the target multiple according to the pressing position.
Each position on the screen corresponds to one magnification factor, and the magnification factors corresponding to the positions are not identical.
Specifically, the pressure-sensitive signal processing means may determine the target multiple corresponding to the position information from the position information of the pressed position.
For example, if the same magnification is used for all the pressed areas of the screen, a small pressing pressure may be applied to the target area of the screen, and the critical value may be reached, so that the pressing operation is difficult for the pressure-sensitive signal processing device, and the pressure-sensitive signal processing device is easy to execute an incorrect instruction.
For example, if the first pressure-sensitive signal is not amplified, the pressure applied to the target area of the screen is 20N, and the pressure-sensitive signal processing device determines that the operation is a pressing operation, and if the first pressure-sensitive signal is amplified by 4 times, the intensity of the pressure-sensitive signal generated when a drag input with a pressure of 5N is applied to the target area of the screen is consistent with that generated when the first pressure-sensitive signal is not amplified and the pressure applied to the target area of the screen is 20N, which makes the pressure-sensitive signal processing device difficult to area and makes erroneous determination easily occur.
So, to the difference in the region that the screen was pressed, set for different pressing multiples for under the prerequisite of promoting the pressing sensitivity that pressure signal processing device detected the screen edge, the condition that can avoid the mistake to touch takes place.
Further optionally, in this embodiment of the present application, in order to avoid that the target area of the screen reaches the detection critical value too early, the amplification factor of the pressure-sensitive signal generated by the pressing pressure close to the target area is smaller than that generated by the pressing pressure far from the target area.
Illustratively, the step 204 may specifically include the following steps 204b1 and 204b 2:
in step 204b1, if the pressed position is located in the first area of the screen, the pressure-sensitive signal processing device determines the target multiple as the first multiple.
In step 204b2, if the pressed position is located in the second area of the screen, the pressure-sensitive signal processing device determines the target multiple to be the second multiple.
The first area is close to the target area, and the second area is far away from the target area. The first multiple is less than the second multiple.
Illustratively, whether one or more pressure-sensitive modules are disposed on the screen, it follows that the magnification is inversely proportional to the distance of the pressed position relative to the pressure-sensitive modules. The pressure-sensitive signal processing means may appropriately decrease the target multiple when the screen is pressed at a position closer to the target area, and may appropriately increase the target multiple when the screen is pressed at a position farther from the target area.
For example, as shown in fig. 5, when the screen is pressed in a region C that is far away from the pressure sensing module (i.e., the target region), the signal strength of the pressure sensing signal generated by the pressure sensing module is low, and the pressure sensing signal processing device may set the amplification factor (i.e., the target factor) to 10 times; when the position where the screen is pressed is located in the area B which is far away from the pressure sensing module (closer to the pressure sensing module than the area C), the signal intensity of the pressure sensing signal generated by the pressure sensing module is not very high, and the amplification factor can be set to be 5 times by the pressure sensing signal processing device; when the position where the screen is pressed is located in the area a closer to the pressure-sensitive module, the signal intensity of the pressure-sensitive signal generated by the pressure-sensitive module is higher, and the amplification factor of the pressure-sensitive signal processing device can be set to be 1.
Therefore, different amplification factors are set for different areas, so that the normal detection of other areas is not influenced while the detection sensitivity of the pressing pressure applied to the edge of the screen is improved.
Further optionally, in this embodiment of the present application, in order to ensure that the signal strength of the pressure-sensitive signal received by the AP can be kept as consistent as possible when the same pressing pressure is applied to different areas of the screen, the target multiple may be gradually increased as the screen is pressed away from the target area.
Illustratively, the step 202 may include the following step 202a or step 202 b:
step 202a, under the condition that the pressed position of the screen is the first area, the pressure-sensitive signal processing device amplifies the first pressure-sensitive signal collected by the pressure-sensitive module by a first multiple to obtain a third pressure-sensitive signal.
Alternatively, the first and second electrodes may be,
step 202b, under the condition that the pressed position of the screen is the second area, the pressure-sensitive signal processing device amplifies the pressure-sensitive signal collected by the pressure-sensitive module by a second multiple to obtain a fourth pressure-sensitive signal.
When the pressing force for pressing the first area is the same as the pressing force for pressing the second area, the absolute difference between the signal intensity of the third pressure-sensitive signal and the signal intensity of the fourth pressure-sensitive signal is smaller than a preset value.
Illustratively, the absolute difference of the signal intensity of the pressure-sensitive signals obtained by applying the same pressing pressure to different areas of the screen after being amplified by the pressure-sensitive signal processing device does not exceed a preset value. Namely, the same pressing pressure is applied to different areas of the screen, and the signal intensity of the obtained pressure-sensitive signals is not greatly different after the pressure-sensitive signals are amplified by the pressure-sensitive signal processing device.
Therefore, different amplification factors are set for different areas, and the signal strength of the pressure sensing signals received by the AP can be kept consistent as much as possible when the same pressing pressure is applied to the different areas of the screen. So that the pressure-sensitive signal processing device can make uniform response to the same magnitude of pressing pressure of different areas.
Optionally, in this embodiment of the application, a screen of the electronic device may be provided with a plurality of pressure-sensitive modules, and sensing ranges of the plurality of pressure-sensitive modules may overlap. At this time, the second pressure-sensitive signal is formed by combining the pressure-sensitive signals collected by different pressure-sensitive modules.
For example, in a case where the screen is provided with a first pressure sensing module and a second pressure sensing module, the first pressure sensing signal is synthesized by a first sub-signal and a second sub-signal. The first sub-signal is a pressure sensing signal collected by the first pressure sensing module, and the second sub-signal is a pressure sensing signal collected by the second pressure sensing module.
For example, the first pressure sensing module and the second pressure sensing module may be disposed in different regions of the screen. The first pressure sensing module and the second pressure sensing module are not limited to one pressure sensing module, that is, the first pressure sensing module or the second pressure sensing module may include at least one pressure sensing module.
Illustratively, the step 204a2 may further include the following steps 204 c:
and 204c, if the pressed position is located in the overlapped area of the sensing range of the first pressure sensing module and the sensing range of the second pressure sensing module, determining the first target multiple and the second target multiple by the pressure sensing signal processing device.
Illustratively, after determining the first target multiple and the second target multiple, the above step 202 may include the following step 204 d:
and 204d, synthesizing the pressure-sensitive signal obtained by amplifying the first sub-signal by the first target multiple and the pressure-sensitive signal obtained by amplifying the second sub-signal by the second target multiple by the pressure-sensitive signal processing device to obtain a second pressure-sensitive signal.
The magnitude of the first target multiple is negatively correlated with the distance between the pressed position and the first pressure sensing module, and the magnitude of the second target multiple is negatively correlated with the distance between the pressed position and the second pressure sensing module.
So, under the condition that the screen is provided with a plurality of pressure modules, pressure signal processing apparatus gathers the pressure signal through a plurality of pressure modules, after the different pressure signals of gathering to different pressure modules enlarge corresponding multiple, synthesizes the second pressure signal for electronic equipment can deal with the design of a plurality of pressure modules.
According to the pressure-sensitive signal processing method provided by the embodiment of the application, under the condition that the pressure-sensitive signal processing device detects that the screen is pressed, the pressure-sensitive signal processing device acquires the first pressure-sensitive signal through the pressure-sensitive module, and then the pressure-sensitive signal processing device obtains the second pressure-sensitive signal by amplifying the first pressure-sensitive signal by the target multiple, so that the pressure-sensitive signal generated in the edge area of the screen can be amplified, and the sensitivity of the electronic equipment to the pressing operation response of the user for pressing the edge of the screen is improved. Meanwhile, different amplification factors are set for different areas of the screen, so that when the same pressing pressure is applied to the different areas of the screen, the signal strength of the pressure sensing signals received by the AP can be kept consistent as much as possible. So that the pressure-sensitive signal processing device can make uniform response to the same magnitude of pressing pressure of different areas.
