Please refer to FIG. 1A to FIG. 1C, which are cross-sectional schematic diagrams of a touch panel structure 100 according to various embodiments of the present application. Please refer to FIG. 2, which is a top view of a touch panel structure 100 according to an embodiment of the present application. As shown in FIG. 1A, the touch panel structure 100 includes three layers. They are a first electrode layer 110, an elastic dielectric layer 180, and a second electrode layer 120 in sequence. The elastic dielectric layer 180 may include a plurality of elastic bodies evenly distributed, which are used between the first electrode layer 110 and the second electrode layer 120. The elastic body may be cylindrical, rectangular, elliptical, etc. When the piezo touch panel structure 100 is subjected to pressure, the elastic body of the elastic dielectric layer 180 is compressed, and the gaps between the elastic bodies are also compressed, so that the capacitance between the electrodes of the first electrode layer 110 and the electrodes of the second electrode layer 120 changes. Accordingly, the pressure value can be estimated by measuring the change in capacitance.

The first electrode layer 110 may include one or more first electrodes. As shown in FIG2 , the first electrode layer 110 includes a plurality of first electrodes 210 parallel to the vertical axis. The second electrode layer 120 may include a plurality of second circuits 220 parallel to the vertical axis, a plurality of third circuits 230 parallel to the horizontal axis, a plurality of second electrodes 222, and a plurality of switch circuits 240. In other words, the first electrode 210 and the second circuit 220 are parallel to the same axis. Each first electrode 210 corresponds to a second circuit 220, and overlaps with all second electrodes 222 to which the corresponding second circuit 220 can be connected.

The first electrode layer 110 can be a film or any flexible substrate, and the first electrode 210 can be disposed on or in the first electrode layer 110 to avoid contact with the second electrode 222 when pressed. The second electrode layer 120 can also be a film, glass, a printed circuit board, etc. This application does not limit the materials of the first electrode layer 110 and the second electrode layer 120, as long as the above-mentioned circuit components can be configured.

In one embodiment, the second electrode 222 and the second circuit 220 can be arranged on the first surface of the second electrode layer 120, and the third circuit 230 and the switch circuit 240 can be arranged on the second surface of the second electrode layer 120. The second electrode layer 120 has a conductive hole that can connect the second electrode 222 and the switch circuit 240. The first surface corresponds to the second surface. In another embodiment, the second circuit 220, the third circuit 230, the second electrode 222 and the switch circuit 240 can be respectively arranged in a multi-layer printed circuit board.

1B , the touch panel structure 100 further includes a third electrode layer 130 below the second electrode layer 120. In this embodiment, the second electrode 222 and the second circuit 220 may be disposed on the second electrode layer 120, and the third circuit 230 and the switch circuit 240 may be disposed on the third electrode layer 130. A connection circuit may be provided between the second electrode layer 120 and the third electrode layer 130.

Referring to FIG. 1C , when the materials of the first electrode layer 110 and the second electrode layer 120 are flexible, the touch panel structure 100 can be folded or bent. For example, the touch panel structure 100 can be placed on a curved surface with a fixed curvature.

The third circuit 230 is used to simultaneously control a plurality of switch circuits 240 arranged along the first axis. When the switch circuit 240 is closed, the second electrode 222 is connected to the corresponding second circuit 220. When the switch circuit 240 is open, the second electrode 222 is disconnected from the second circuit 220. The switch circuit 240 may include at least one transistor element, such as a field effect transistor.

The first electrode 210 and the third circuit 230 are respectively connected to the driving circuit module of the pressure sensing processing device, and the second circuit 220 is respectively connected to the sensing circuit module of the pressure sensing processing device. When pressure sensing is to be performed on an area near a third circuit 230, the plurality of switch circuits 240 corresponding to the third circuit 230 can be controlled so that the second electrode 222 corresponding to the third circuit 230 is connected to the second circuit 220 through its switch circuit 240. And the driving signal is provided to all the first electrodes 210. Since there is capacitance between the first electrode 210 and the second electrode 222, the second electrode 222 can transmit the sensed driving signal to the sensing circuit module through the second circuit 220. When the driving signal sensed by the sensing circuit module is abnormal, it means that an object is pressing the second electrode 222 or a position near it.

After the corresponding pressure sensing of a third circuit 230 is completed, a pressure value array can be obtained. The number of elements in the pressure value array is the number of the second circuits 220. Then, the next third circuit 230 can be selected to perform the corresponding pressure sensing to obtain another pressure value array. When all third circuits 230 have completed the corresponding pressure sensing, it means that the entire pressure sensing array structure has been detected. Next, the above-mentioned multiple pressure value arrays can be combined into a pressure value image according to the position of the corresponding third circuit 230. The number of the vertical axis of the pressure value image is the number of the third circuits 230, and the number of the horizontal axis is the number of the first electrodes 210 or the number of the second circuits 220.

This pressure value image can be compared with a reference image that is not normally under pressure to find a difference image. The reference image is a pressure value image sensed when not under pressure. Next, one or more ranges under pressure are found based on the difference image. Then, the center of gravity or center of each range is found as the pressure point of the range. Finally, the pressure value measured near the pressure point is weighted and averaged according to the distance between the pressure point and the measurement point to obtain the pressure value of the pressure point. A person of ordinary skill in the art can understand that the above-mentioned method of obtaining the pressure value of a pressure point from a pressure value image is known, and the calculation method of the prior art can be applied.

The pressure value image or difference image obtained above is a full image obtained by using all the second circuits 220, and has the highest resolution. In other words, the drive signal must be supplied to all the first electrodes 210. When the highest resolution is not required, the drive signal can be supplied to half or less of the first electrodes 210. For the convenience of explanation, each first electrode 210, second circuit 222, and third circuit 230 can be numbered in sequence.

For example, the driving signal can be supplied to the odd-numbered first electrodes 210, and only the odd-numbered second circuits 220 are used for sensing. In this way, an odd-numbered pressure value array is obtained. The number of elements in the odd-numbered pressure value array is half the number of elements in the normal pressure value array.

Similarly, the driving signal can be supplied to the even-numbered first electrodes 210, and only the even-numbered second circuits 220 are used for sensing. In this way, an even-numbered pressure value array is obtained. The number of elements in the even-numbered pressure value array is half of the number of elements in the normal pressure value array.

An odd-numbered pressure value image with the number of elements halved can be formed using multiple odd-numbered pressure value arrays, or an even-numbered pressure value image with the number of elements halved can be formed using multiple even-numbered pressure value arrays. Using these pressure value images with the number of elements halved, pressure positions with a resolution halved can be obtained.

For example, the driving signal can be supplied to the 3i+xth first electrode 210, where i is a natural number and x is an integer from 0 to 2, and only the 3i+xth second circuit 220 is used for sensing. In this way, a pressure value array of one-third the size is obtained. The number of elements in the pressure value array is one-third of the number of elements in the ordinary pressure value array.

A plurality of 3i+x-th pressure value arrays can be used to form a pressure value image with the number of elements reduced by one third. By using these pressure value images with the number of elements reduced by one third, pressure positions with a resolution reduced by one third can be obtained.

In another embodiment, a pipeline method can be used to obtain a complete pressure value image. First, an odd-numbered first pressure value image can be obtained during the first detection, and an even-numbered second pressure value image can be obtained during the second detection. The first pressure value image and the second pressure value image are interlaced to form a complete pressure value image. The pressure point and its pressure value can be obtained using this complete pressure value image.

During the third detection, the third odd-numbered pressure value image can also be obtained, and the second pressure value image and the third pressure value image are interlaced to form another complete pressure value image. The pressure point and its pressure value can be obtained using another complete pressure value image. Similarly, except for the first detection step of reducing the resolution, a complete pressure value image can be obtained after each detection step of reducing the resolution, so as to further obtain the pressure point and its pressure value.

Previously mentioned is to use multiple pressure value images with reduced resolution to obtain a complete pressure value image, so as to further obtain the pressure point and its pressure value. Next, the present application provides to obtain a proximity value image with reduced resolution while obtaining the pressure value image with reduced resolution, so as to obtain a complete proximity value image, so as to further obtain the proximity point.

When the driving signal is supplied to the odd-numbered first electrodes 210, the potential of the even-numbered first electrodes 210 is made to float. In this way, the power lines associated with the driving signal will start from the odd-numbered first electrodes 210, pass through the space above the touch panel, and reach the even-numbered second electrodes 222 through the even-numbered first electrodes 210. When an external object passes through the space above the touch panel, it will affect the power lines associated with the driving signal, thereby changing the potential of the even-numbered second circuit 220. Based on this, an even-numbered proximity value image can be obtained. Similarly, a proximity point with reduced resolution and a pressure value corresponding to the proximity point can be obtained by a similar method.

Similarly, when the driving signal is supplied to the even-numbered first electrode 210, the potential of the odd-numbered first electrode 210 is floated. In this way, the power line associated with the driving signal will start from the even-numbered first electrode 210, pass through the space above the touch panel, and reach the odd-numbered second electrode 222 through the odd-numbered first electrode 210. When an external object passes through the space above the touch panel, it will affect the power line associated with the driving signal, thereby changing the potential of the odd-numbered second circuit 220. Based on this, the odd-numbered proximity value image can be obtained. Similarly, the proximity point with reduced resolution and the corresponding pressure value of the proximity point can be obtained by a similar method.

In another embodiment, a pipeline method can be used to obtain a complete pressure value image and a proximity value image. First, an odd-numbered first pressure value image and an even-numbered first proximity value image can be obtained during the first detection, and an even-numbered second pressure value image and an odd-numbered second proximity value image can be obtained during the second detection, and the first pressure value image and the second pressure value image are interlaced to form a complete pressure value image. The pressure point and its pressure value can be obtained using this complete pressure value image. The first proximity value image and the second proximity value image are interlaced to form a complete proximity value image. The proximity point and the pressure point corresponding to the proximity point and its pressure value can be obtained using this complete proximity value image.

During the third detection, the third odd-numbered pressure value image and the third even-numbered proximity value image can also be obtained, and the second pressure value image and the third pressure value image are interlaced to form another complete pressure value image, and the second proximity value image and the third proximity value image are interlaced to form another complete proximity value image. The pressure point and its pressure value can be obtained using another complete pressure value image. The proximity point and its pressure value can be obtained using another complete proximity value image. Similarly, except for the first detection step of reducing the resolution, the complete pressure value image and the proximity value image can be obtained after each detection step of reducing the resolution, so as to further obtain the pressure point and its pressure value and the proximity point and its pressure value.

In one embodiment, it is not necessary to obtain the reduced-resolution pressure value image and the proximity value image at the same time. The reduced-resolution pressure value image and the proximity value image can be detected alternately, and the complete pressure value image and the proximity value image can be pieced together in a pipeline manner.

In addition to passive external objects, when a stylus or a touchpad eraser that actively sends out an electrical signal is to be detected, the electrical signal may include a signal with a frequency different from the drive signal. For example, when the drive signal includes a signal with a first frequency, the electrical signal of the stylus or the touchpad eraser includes a signal with a second frequency. The first frequency and the second frequency may not be mutually resonant frequencies.

The electrical signal can be transmitted from the first electrode 210 to the second electrode 222, and then reaches the second circuit 220 via the switch circuit 240. While the second circuit 220 is used to detect the driving signal including the first frequency in order to obtain the pressure value image and the proximity value image with reduced resolution, the second circuit 220 can be used to detect the electrical signal including the second frequency. Since each second circuit 220 can be used to detect the first frequency signal and the second frequency signal at the same time, the electrical signal value of each second circuit 220 for the second frequency signal can form an electrical signal array with lossless resolution. Multiple electrical signal arrays are then combined to form a complete electrical signal image. Based on the complete electrical signal image, the proximity point of the active pen can be obtained.

When multiple active styluses are to be detected, these styluses can be made to actively emit electrical signals containing different frequencies. Since each second circuit 220 can be used to detect N frequency signals at the same time, where N is a natural number. Each second circuit 220 can form a lossless resolution (N-1) electrical signal array for the electrical signal values of the (N-1) frequency signals contained in the active stylus. Multiple electrical signal arrays are then combined to form complete (N-1) electrical signal images. Based on the complete (N-1) electrical signal images, the (N-1) proximity points of the active pens can be obtained respectively.

Even if M active styluses send out the same second frequency signal, since the third circuit 230 controls the switch circuit 240, the third circuit 230 can be detected one by one, so M proximity points corresponding to the M styluses can be obtained in the electrical signal image, where M is a positive integer greater than one.

In the case where a portion of the touch panel is covered by a conductive liquid, another sensing method can be used to detect a nearby external object, but the present application does not limit the applicable scenarios of the following sensing method. The potentials of all first electrodes 210 can be floated and all switch circuits 240 can be open, and the third circuit 230 and the second circuit 220 can be detected separately. The detection result of each third circuit 230 can form a proximity value array on the vertical axis, and the detection result of each second circuit can form a proximity value array on the horizontal axis. The frequency contained in the signal sent by the third circuit 230 may not affect the open state of the switch circuit 240.

When an external conductive object is suspended or close to some of the third circuits 230 and the second circuits 220, the potentials of these third circuits 230 and the second circuits 220 will be affected. Therefore, the detected proximity values will change. When only one external conductive object is suspended or close, the proximity value array of the vertical axis can be used to find a vertical axis position, and the proximity value of the horizontal axis can be used to find a horizontal axis position. The positions of these two vertical axes and the horizontal axis can correspond to the projection point of the external conductive object on the touch panel. When two external conductive objects are suspended or close, the proximity value array of the vertical axis can be used to find one or two vertical axis positions, and the proximity value of the horizontal axis can be used to find one or two horizontal axis positions. The positions of the four vertical axes and the horizontal axis can correspond to at most four projection points of the two external conductive objects on the touch panel. The four projection positions can form a rectangle, and the two sets of diagonal points of the rectangle may be the real projection points of the two external conductive objects.

In other words, using the above-mentioned sensing method, the projection point of a single external conductive object or the rectangle of the projection points of two external conductive objects can be obtained. By using the change in the shape of the rectangle, the change in the distance between the two external conductive objects can be obtained in order to obtain the input of certain gestures, such as zooming in or out gestures. In addition, when a vertex of the rectangle corresponds to the original projection point, it can be determined that its diagonal point is the projection point of the newly added external conductive object, and the true projection point of the two external conductive objects can be obtained. Alternatively, the true projection point can be obtained by comparing the proximity value image or the proximity point.

If there is no causal relationship between any two steps, the present application does not limit the order of the two steps. Compared with the touch processing method 400, the touch processing method 500 is used to obtain a pressure value interlaced image with fewer elements, and is used to obtain a pressure point with a lower resolution and its corresponding pressure value. The touch processing method 500 uses some steps of the touch processing method 400, which will not be described here. The touch processing method 500 starts from step 410.

Please refer to FIG. 6 , which is a flowchart of a touch processing method 600 according to an embodiment of the present application. The touch processing method 600 can be applied to the touch system 300 of FIG. 3 , and is particularly applicable to the processor module 314 in the touch processing device 310 . Instructions and data stored in a non-volatile memory can be used to enable the processor module 314 to execute these instructions so as to implement the touch processing method 600 . If there is no causal relationship between any two steps, the present application does not limit the order of the two steps. Compared with the touch processing method 500, the touch processing method 600 is used to obtain a proximity value interlaced image with fewer elements, and is used to obtain a proximity point with lower resolution and its corresponding pressure value. The touch processing method 600 uses some steps of the touch processing methods 400 and 500, which are not described here.

Please refer to FIG. 7 , which is a flowchart of a touch processing method 700 according to an embodiment of the present application. The touch processing method 700 can be applied to the touch system 300 of FIG. 3 , and is particularly applicable to the processor module 314 in the touch processing device 310 . Instructions and data stored in a non-volatile memory can be used to enable the processor module 314 to execute these instructions so as to implement the touch processing method 700 . If there is no causal relationship between any two steps, the present application does not limit the order of the two steps. Using the touch processing methods 500 and 600, the touch processing method 700 is used to obtain a proximity value interlaced image and a pressure value interlaced image with fewer elements, which are used to obtain a proximity point with lower resolution and its corresponding pressure value, and a pressure point with lower resolution and its corresponding pressure value, respectively. The touch processing method 700 uses some steps of the touch processing methods 400 to 600, which are not described here. The multiple first electrodes specified in step 520 of the touch processing method 700 can be odd-numbered first electrodes or even-numbered first electrodes. The touch processing method 700 starts from step 410.

Step 730: Sense the driving signals sensed by the second circuits and the second electrodes thereof to obtain a pressure value interlaced array and a proximity value interlaced array. The pressure value interlaced array corresponds to the sensing results of the second circuits corresponding to the designated first electrodes. The proximity value interlaced array corresponds to the sensing results of the second circuits corresponding to the undesignated first electrodes. The execution time of step 520 and step 730 at least partially overlaps.

Step 770: All the pressure value interleaved arrays are combined into a pressure value interleaved image according to the positions of the third circuits to which they correspond, and all the proximity value interleaved arrays are combined into a proximity value interleaved image according to the positions of the third circuits to which they correspond.

Step 780: Calculate one or more pressure points based on the pressure value interlaced image, and calculate one or more proximity points based on the proximity value interlaced image. This step may also include calculating the weighted pressure value of the pressure point and the weighted pressure value of the proximity point.

In step 780, since the proximity point and the pressure point may be within a corresponding distance, the position of the proximity point and the weighted pressure value of the pressure point can be reported to the host. When the proximity point cannot be matched to the pressure point, it means that a suspended external conductive object is close to the proximity point, so there is no need to report the pressure value calculated by the proximity point.

Please refer to FIG. 8A , which is a flowchart of a touch processing method 800A according to an embodiment of the present application. The touch processing method 800A can be applied to the touch system 300 of FIG. 3 , and in particular to the processor module 314 in the touch processing device 310 . The instructions and data stored in the non-volatile memory can be used to make the processor module 314 execute these instructions to implement the touch processing method 800A. If there is no causal relationship between any two steps, the present application does not limit the order of the two steps. Using the touch processing methods 500 and 600, the touch processing method 800A is used to continuously obtain a proximity value interlaced image and a pressure value interlaced image with fewer elements, and to combine two consecutive proximity value interlaced images into a complete proximity value image, and to combine two consecutive pressure value interlaced images into a complete pressure value image. Since the proximity value interlaced images detected two times before and after are composed according to different first electrodes, the proximity value interlaced images detected two times before and after can be interlaced to form a complete proximity value image, and the pressure value interlaced images detected two times before and after can be interlaced to form a complete pressure value image. The touch processing method 800A uses some steps of the touch processing methods 400 to 700 , which will not be described in detail. The touch processing method 800A starts from step 810 .

Step 810: Reset the natural number i to 1, specify that the staggered multiple first electrodes form a first set, and specify that the remaining multiple first electrodes form a second set. In one embodiment, the first set includes odd-numbered first electrodes, and the second electrodes include even-numbered second electrodes. Conversely, in another embodiment, the first set includes even-numbered first electrodes, and the second set includes odd-numbered first electrodes. The present application does not limit the first electrode specified in step 810 to an odd-numbered or even-numbered first electrode.

Step 820: For the first set, execute steps 410 to 570 shown in FIG4 to obtain the i-th pressure value interlaced image. For example, when the first set includes odd-numbered first electrodes, the i-th pressure value interlaced image includes the sensing results of the odd-numbered second electrodes corresponding to the odd-numbered first electrodes.

Step 830: For the second set, execute steps 410 to 670 shown in FIG5 to obtain the i-th proximity value interlaced image. For example, when the second set includes even-numbered first electrodes, the i-th proximity value interlaced image includes the sensing results of the even-numbered second electrodes corresponding to the even-numbered first electrodes.

Step 840: Increase the value of i by 1 and swap the first set with the second set.

Step 850: Determine whether i is greater than 2, so only the first time step 850 is executed will it be judged as false. When the judgment result is true, it means that there have been two consecutive detections of proximity value interlaced images and pressure value interlaced images, and the process proceeds to step 860. Otherwise, the process returns to step 820.

Step 860: The i-1th pressure value interlaced image and the i-2th pressure value interlaced image are made to form a complete pressure value image, and the i-1th proximity value interlaced image and the i-2th proximity value interlaced image are made to form a complete proximity value image. Since step 840 has increased i+1, the value of i-1 in step 860 is actually equal to the value of i in step 830. Since the i-1th pressure value interlaced image and the i-2th pressure value interlaced image correspond to the first set and the second set respectively, the element interlaced images of the i-1th pressure value interlaced image and the i-2th pressure value interlaced image can be interlaced to form a complete pressure value image. Similarly, since the i-1th closest value interlaced image and the i-2th closest value interlaced image correspond to the first set and the second set respectively, the element interlaced images of the i-1th closest value interlaced image and the i-2th closest value interlaced image can be interlaced to form a complete pressure value image.

Step 870: Calculate one or more pressure points based on the pressure value image, and calculate one or more proximity points based on the proximity value image. In one embodiment, the pressure value corresponding to each pressure point can be calculated based on the pressure value image. In one embodiment, the pressure value corresponding to each proximity point can be calculated based on the proximity value image.

The instructions and data stored in the non-volatile memory can be used to make the processor module 314 execute these instructions so as to implement the touch processing method 900 . If there is no causal relationship between any two steps, the present application does not limit the order of the two steps. Like the touch processing methods 800A and 800B, the touch processing method 900 is used to continuously obtain proximity value interlaced images and pressure value interlaced images with fewer elements, and to combine two consecutive proximity value interlaced images into a complete proximity value image, and to combine two consecutive pressure value interlaced images into a complete pressure value image. Since the proximity value interlaced images detected two times before and after are composed according to different first electrodes, the proximity value interlaced images detected two times before and after can be interlaced to form a complete proximity value image, and the pressure value interlaced images detected two times before and after can be interlaced to form a complete pressure value image. The difference between the touch processing method 900 and the touch processing method 800A and 800B is that the touch processing method 900 simultaneously obtains the proximity value interlaced image and the pressure value interlaced image in one detection. The touch processing method 900 uses some steps of the touch processing method 400 to 800A and 800B, which will not be described here. The touch processing method 900 starts from step 810.

Step 910: Provide a driving signal to the first set.

Step 920: All the pressure value interleaved arrays are combined into an i-th pressure value interleaved image according to the positions of the third circuits to which they correspond, and all the proximity value interleaved arrays are combined into an i-th proximity value interleaved image according to the positions of the third circuits to which they correspond.

The touch processing method 1500A is similar to the touch processing method 1000 shown in FIG. 10 , and is used to detect the electrical signal actively sent by a transmitter such as a stylus or a touch eraser. The difference is that when the frequency of the electrical signal is different from the frequency of the drive signal, and the sensing circuit module 313 is capable of detecting the frequency of the electrical signal and the frequency of the drive signal at the same time, the pressure value interlaced image, the proximity value interlaced image and the electrical signal value image can be obtained in one detection.

After obtaining the complete electrical signal value image, one or more transmitter positions can be calculated and reported. Two consecutive proximity value interlaced images are combined into a complete proximity value image, and two consecutive pressure value interlaced images are combined into a complete pressure value image. Since the proximity value interlaced images detected two times before and after are composed according to different first electrodes, the proximity value interlaced images detected two times before and after can be interlaced to form a complete proximity value image, and the pressure value interlaced images detected two times before and after can be interlaced to form a complete pressure value image.

The touch processing method 1700A uses the principle of self-capacitance to make the potential of the first electrode covering the second circuit, the second electrode and the third circuit float. When an external object approaches, it will affect the second circuit and the third circuit. Accordingly, one or more coordinates of one axis can be obtained based on the self-capacitance sensing results of all the second circuits. Then, one or more coordinates of another axis can be obtained based on the self-capacitance sensing results of all the third circuits. The touch processing method 1700A starts from step 1710. The execution time of step 1730 and step 1740 can overlap.

Step 1710: Make the potentials of all first electrodes float.

Step 1720: Provide a first driving signal to all third circuits to open all switch circuits.

Step 1730: Provide a second driving signal to all third circuits, and sense the changes of the second driving signals of all the third circuits to form a first axis sensing array. The frequency contained in the second driving signal does not affect the opening or closing of the switch circuit.

Step 1740: Provide a second driving signal to all second circuits, and sense changes in the second driving signals of all the second circuits to form a second axis sensing array.

Step 1750: Calculate one or more first-axis coordinates according to the first-axis sensing array, and calculate one or more second-axis coordinates according to the second-axis sensing array.

Please refer to FIG. 17B , which is a schematic diagram of a touch processing method 1700B according to an embodiment of the present application. The embodiment shown in FIG. 17B is a variation of the embodiment shown in FIG. 17A . The difference is that step 1720 is replaced by step 1725 .

Step 1725: Provide a first driving signal to all third circuits to close all switch circuits. That is, the sensing range of step 1740 includes not only the second circuit but also the second electrode.

Please refer to FIG. 17C , which is a schematic diagram of a process of a touch processing method 1700C according to an embodiment of the present application. The embodiment shown in FIG. 17C is a variation of the embodiment shown in FIG. 17A . The difference is that step 1740 is replaced by step 1745 .

Step 1745: Provide the third driving signal to all the second circuits, and sense the changes of the third driving signals of all the second circuits to form a second axis sensing array. In order to avoid electromagnetic interference caused by the second circuit and the third circuit using the same second driving signal, the second circuit and the third circuit can use different driving signals, such as signals containing different frequencies, to reduce electromagnetic interference and increase sensing accuracy.

In each embodiment of the present application, the sensed pressure value depends on the change in the distance between the first electrode corresponding to the pressure point and the second electrode below it, and the sensed proximity value depends on the blocking of the electric field between the first electrode adjacent to the proximity point and the second electrode below the proximity point. These two capacitance changes may not be in the same order of magnitude. Therefore, when measuring the pressure value, the amplification gain value to be set by the sensing circuit module 313 may be different from the amplification gain value corresponding to the proximity value. In other words, when implementing the touch processing methods 700, 900, 1400, and 1600, the amplification gain values corresponding to the adjacent second circuits may be different. Similarly, the amplification gain values corresponding to the detection driving signal and the detection electrical signal may be different.
