AI Technical Summary
Under-screen sensors in full-screen devices cause noise interference, leading to touch line deviation and touch point jumping due to inconsistent noise levels across the touch panel.
The touch panel is divided into two areas with independent touch circuits and distinct noise reduction processing parameters, where the second touch area opposite the under-screen sensor receives specialized noise reduction to mitigate interference.
This approach effectively reduces touch line offset and touch point jumping by isolating and optimizing noise reduction for areas affected by under-screen sensors, enhancing overall touch performance.

[0002] In the related art, full-screen devices have a higher screen-to-body ratio and a better user experience. In order to achieve a higher screen-to-body ratio, some sensors, such as the front camera and fingerprint sensor, are usually set as under-screen sensors. These under-screen sensors will interfere with the touch performance of the touch panel above them, such as generating noise signals, etc. These noise signals will cause the noise intensity of the specific area relative to the under-screen sensor to be different from that of other areas. Therefore, even after the overall noise signal of the touch panel is reduced, these areas will still have noise interference, resulting in problems such as touch line deviation and touch point jump. Summary of the invention

[0026] Combine the following Figures 1 to 7 A touch panel and an electronic device according to embodiments of the present application are described.
[0027] In some embodiments of the present application, a touch panel is provided. Figure 1 , Figure 2 and Figure 3 The structure diagram of the touch panel 10 of some embodiments of the present application is shown as follows: Figure 1 , Figure 2 and Figure 3 As shown, the touch panel 10 includes:
[0028] A first touch control area 12, the first touch control area 12 includes a first touch control circuit 120;
[0029] A second touch control area 14, the second touch control area 14 is adjacent to at least a portion of the first touch control area, the second touch control area 14 includes a second touch control circuit 140, and the second touch control circuit 140 is not connected to the first touch control circuit 120;
[0030] A touch chip 16, the touch chip 16 is electrically connected to the first touch circuit 120 and the second touch circuit 140, and the touch chip 16 is used to control the first touch circuit 120 based on a first driving parameter, and to control the second touch circuit 140 based on a second driving parameter; wherein the first driving parameter is used to instruct the touch chip to perform a first noise reduction processing on the touch operation information collected by the first touch circuit, and the second driving parameter is used to instruct the touch chip to perform a second noise reduction processing on the touch operation information collected by the second touch circuit, and the first noise reduction processing and the second noise reduction processing have different noise reduction processing methods.
[0031] In the embodiment of the present application, the touch panel 10 is a touch panel 10 of an electronic device 20 such as a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted frame 28 device, etc. The following is an example of the touch panel 10 being applied to a mobile phone.
[0032] For mobile phones, the concept of full screen refers to increasing the screen-to-body ratio of the mobile phone as much as possible, so as to set a larger display screen as much as possible in a limited volume, thereby improving the user experience. In order to achieve a full screen, or to get a larger screen-to-body ratio, some sensors originally set on the front of the phone, such as the front camera, face detection sensor, fingerprint sensor, light sensor and other devices, need to be set under the screen.
[0033] Taking the front camera as an example, since the front camera is embedded at the bottom of the display panel 22, as the capabilities of the front camera increase, the front camera will interfere with the touch performance of the touch panel 10 on top of it. For example, for a general touch panel 10, it uses a unified noise reduction parameter to reduce noise interference and ensure the accuracy of touch detection. However, due to the presence of the front camera, the touch sensor in the area near the front camera is interfered by the front camera, thereby generating greater noise than other areas. This results in a strong noise signal still remaining in the area after unified noise reduction, causing touch point jumps or click offsets in this area.
[0034] To address the above problem, the embodiment of the present application divides the touch panel 10 into a first touch area 12 and a second touch area 14, wherein the first touch area 12 is a general touch area covering a larger area of the mobile phone touch screen, and the second touch area 14 is a touch area opposite to the under-screen sensor, such as the front camera. Therefore, compared with the first touch area 12, the second touch area 14 will be interfered by external noise signals, resulting in stronger noise.
[0035] For example, Figure 1 As shown, TX01, TX02 ... TX20 are lines connected to the transmitting end of the touch chip 16. RX01, RX02 ... RX23 are lines connected to the receiving end of the touch chip 16. The TX channel of the touch chip 16 sends a signal, and the RX channel receives the change in the finger touch, thereby calculating the touch coordinates and realizing touch positioning.
[0036] Figure 1 and Figure 2 The avoidance area 146 in the figure corresponds to the opening of the front camera. Due to the existence of the avoidance area 146 and the front camera, the noise of the touch sensor near them is stronger.
[0037] In this regard, the present application sets independent first touch circuits 120 and second touch circuits 140 for the first touch area 12 and the second touch area 14, respectively. The first touch circuits 120 and the second touch circuits 140 are separated from each other and routed independently, and are independently connected to the touch chip 16, that is, the touch detection of the first touch area 12 and the second touch area 14 are separated. Figure 3 As shown, the second touch control circuit 140 is not connected to the first touch control circuit 120 and the two are separated from each other, so that the noise signal in the second touch control circuit 140 will not spread to the first touch control circuit 120, that is, it will not affect the touch detection of the first touch control circuit 120.
[0038] At the same time, the touch chip 16 detects the touch operations in the first touch area 12 and the second touch area 14 based on different first driving parameters and second driving parameters, respectively, wherein the first driving parameter is used to instruct the touch chip 16 to perform a first noise reduction processing on the touch operation information collected by the first touch circuit 120, and the second driving parameter is used to instruct the touch chip 16 to perform a second noise reduction processing on the touch operation information collected by the second touch circuit 140. The first noise reduction processing and the second noise reduction processing have different noise reduction processing methods. Therefore, for the general first touch area 12, the normal driving parameters with general noise reduction parameters can be used to control its operation, and for the second touch area 14 with stronger noise interference, the driving parameters with stronger noise reduction parameters can be used to control it.
[0039] Exemplarily, the touch chip 16 drives the first touch circuit 120 and the second touch circuit 140 to operate through the first driving parameter and the second driving parameter respectively, and obtains detection information of the first touch circuit and the second touch circuit 140, and reports the obtained detection information to the main control board of the mobile phone, and calculates the touch information through the main controller or the touch calculation chip on the main control board to obtain the real coordinates of the user's touch operation.
[0040] The present application can perform independent touch control for the area where the under-screen sensor is set, or perform different noise reduction processing for the two different driving circuits, so as to avoid interference problems caused by higher noise in the touch area opposite to the under-screen sensor, and reduce problems such as touch line offset and touch jump point.
[0041] In some embodiments of the present application, Figure 1 , Figure 2 and Figure 3 As shown, the first touch control circuit 120 includes N first touch control units 122, the N first touch control units 122 form a first sensor array 124, the first sensor array 124 includes an avoidance area 126, and the first touch control units 122 avoid the avoidance area 126;
[0042] The second touch control circuit 140 includes M second touch control units 142 . The M second touch control units 142 form a second sensor array 144 . The second sensor array 144 is located in the avoidance area 126 . Wherein, N and M are both positive integers, and N>M.
[0043] In the embodiment of the present application, for example, a touch sensor, including a first touch unit 122 and a second touch unit 142, can be a touch electrode. The first touch circuit 120 includes N first touch units 122, such as Figure 1 As shown, N first touch control units 122 are distributed in an array in the length direction and the width direction of the touch panel 10 , respectively, so as to form a first sensor array 124 .
[0044] The avoidance area 126 is specifically opposite to the position of the under-screen sensor, such as the front camera, the under-screen fingerprint recognition sensor, etc., so as to avoid the setting position of the under-screen sensor. It can be understood that the touch sensor in the avoidance area 126 may be affected by the under-screen sensor, so the first touch unit 122 is set to avoid the avoidance area 126, so as to ensure that all the first touch units 122 in the first touch circuit 120 are not disturbed by the noise of the under-screen sensor.
[0045] Similar to the first touch control circuit 120, the second touch control circuit 140 includes M second touch control units 142 arranged in an array, and the M second touch control units 142 are also arranged in an array in the length direction and the width direction of the touch panel 10, thereby forming a second sensor array 144. The second touch control circuit 140 is used to detect touch signals in the avoidance area 126, that is, in the area that may be interfered by the under-screen sensor.
[0046] By separately setting up an independent first touch circuit 120 and a second touch circuit 140, different driving parameters can be used to detect touch operations according to different situations of interference from the under-screen sensor. Therefore, interference from under-screen sensors such as the front camera can be avoided, and problems such as touch line offset and touch jump can be avoided, thereby improving the touch performance of the under-screen sensor setting area.
[0047] In some embodiments of the present application, Figure 1 , Figure 2 and Figure 3 As shown, the first sensor array 124 includes a first sub-array 1242 and a second sub-array 1244, the first sub-array 1242 includes a plurality of first sensor groups 12422 distributed along a first direction, the second sub-array 1244 includes a second sensor group 12442 and a third sensor group 12444 distributed along the first direction, and the second sensor group 12442 and the third sensor group 12444 are respectively located on both sides of the avoidance area 126; wherein the first sensor group 12422, the second sensor group 12442 and the third sensor group 12444 each include at least two first touch units 122 distributed along the second direction, and the first direction and the second direction are different.
[0048] In the embodiment of the present application, for a general touch panel 10, it can be regarded as an array structure composed of "multiple rows" of touch sensors, wherein each row of touch sensors can be regarded as a "sensor group", wherein each sensor group includes multiple touch sensors distributed along a first direction, that is, the width direction of the touch panel 10, and multiple sensor groups are distributed along a second direction, that is, the length direction of the touch panel 10.
[0049] Due to the existence of the avoidance zone 126, part of the sensor group is separated by the avoidance zone 126. Here, the part not separated by the avoidance zone 126 is defined as the first sub-array 1242, and the part separated by the avoidance zone 126 is defined as the second sub-array 1244. The sensor group in the first sub-array 1242 is defined as the first sensor group 12422, as shown in FIG. Figure 1 , Figure 2 and Figure 3 As shown, the first sensor group 12422 is not separated by the avoidance zone 126. The sensor group in the second sub-array 1244 includes two parts separated by the avoidance zone 126, the first part is the second sensor group 12442, and the other part is the third sensor group 12444. Figure 1 , Figure 2 and Figure 3 For example, the second sensor group 12442 is located at the left side of the avoidance area 126 , and the third sensor group 12444 is located at the right side of the avoidance area 126 .
[0050] The present application separates the original sensor group for the avoidance area 126 to form a new touch pattern, thereby avoiding interference from the under-screen sensor and improving the touch performance of the under-screen sensor area.
[0051] In some embodiments of the present application, optionally, Figure 1 , Figure 2 and Figure 3 As shown, the second touch control circuit 140 further includes a clearance area 146 , and the second touch control unit 142 avoids the clearance area 146 .
[0052] In the embodiment of the present application, the clearing area 146 corresponds to the opening area of the under-screen sensor. Taking the under-screen sensor as a front camera as an example, the clearing area 146 is the opening area of the front camera. Taking the under-screen sensor as an ultrasonic fingerprint sensor as an example, the clearing area 146 is the opening area of the under-screen fingerprint.
[0053] like Figure 3As shown, the area near the avoidance zone 146 is divided into a second touch area 14, and an independent second touch circuit 140 is set in the area, so that the touch image and routing of the under-screen sensor area can be independently designed, and the operation of the first touch circuit 120 and the second touch circuit 140 is controlled based on different touch parameters, thereby solving the interference of under-screen sensors such as the front camera on the touch performance and improving the touch performance.
[0054] In some embodiments of the present application, the first driving parameter and the second driving parameter each include at least one of the following: driving voltage, driving frequency, and scanning mode.
[0055] In the embodiment of the present application, the first touch circuit 120 and the second touch circuit 140 can be driven respectively by different driving voltages. For example, the first touch circuit 120 is driven by the first driving voltage, and the second touch circuit 140 is driven by the second driving voltage, and the second driving voltage is greater than the first driving voltage. Through a higher driving voltage, the noise impact caused by the under-screen sensor can be reduced, and the touch performance of the second touch area 14 corresponding to the under-screen sensor can be improved.
[0056] Exemplarily, the first touch control circuit 120 and the second touch control circuit 140 may be driven respectively by different driving frequencies. Exemplarily, the first touch control circuit 120 is driven by a first driving frequency, and the second touch control circuit 140 is driven by a second driving frequency, and the second driving frequency is different from the first driving frequency. By driving the first touch control circuit 120 and the second touch control circuit 140 respectively by differentiated driving frequencies, it is possible to avoid touch interference caused by the under-screen sensor.
[0057] Exemplarily, the scanning modes of the first touch circuit 120 and the second touch circuit can also be distinguished. The touch circuit in the touch area can be regarded as a sensor array composed of a plurality of touch sensors, and the sensor array can be regarded as a sensor group composed of a plurality of rows or columns. Assuming that a touch area includes 20 columns of sensor groups, and each sensor group includes 20 touch sensors, then a sensor array is an array composed of 20×20=400 touch sensors. For the scanning mode, exemplarily, one scanning mode can be to scan all 20 columns of sensor groups at one time, and another scanning mode can be to first scan a total of 10 columns of sensor groups 1-10, and then scan 10 columns of sensor groups 11-20.
[0058] By distinguishing the first touch area 12 and the second touch area 14 by differentiating different scanning modes, it is also possible to perform separate noise reduction processing on the two different touch areas, thereby improving the touch accuracy of the sensor area under the screen.

Figure 5 As shown, the touch panel 10 is integrated in the display panel 22, wherein, as shown in FIG. Figure 5 As shown, the display panel 22 specifically includes a multi-layer structure. Specifically, the display panel 22 includes a PET (Polyethylene terephthalate) layer, which is also a flexible cover layer. The display panel 22 also includes an OCA (Optical Clear Adhesive) layer, which is used to bond the PET layer and the touch panel 10.
[0062] The display panel 22 further includes a Panel (display) layer, an FPC (Flexible Printed Circuit) layer and Other (other) layers.
[0063] The touch panel 10 and the display panel 22 in the embodiment of the present application are integrated, which can improve the integration and modularity of the electronic device 20 .
[0064] In some embodiments of the present application, Figure 6 Schematic diagrams showing some real-time display panel 22 results of the present application are shown, such as Figure 4 and Figure 6 As shown, the electronic device 20 further includes a display panel 22 , and the touch panel 10 is attached to the display panel 22 .
[0065] In the embodiment of the present application, the touch panel 10 is an external touch design, and the touch panel 10 is bonded to the display panel 22 , so that the touch panel 10 involved in the present application can be compatible with the existing display panel 22 , broadening the application scenarios of the touch panel 10 .
[0066] In some embodiments of the present application, Figure 1 and Figure 4 As shown, the touch panel 10 includes a first touch area 12 and a second touch area 14, and the electronic device 20 also includes: a main body 24, the touch panel 10 and the display panel 22 are connected to the main body 24, and there is a mounting cavity 242 between the main body 24 and the touch panel 10; a sensor 26, the sensor 26 is arranged in the mounting cavity 242, and is arranged opposite to the second touch area 14.
[0067] In the embodiment of the present application, the electronic device 20 is a mobile phone as an example, the body 24 is the overall shell of the mobile phone, and the body 24 and the display panel 22 form an installation cavity 242, and the battery, main control board and other components of the electronic device 20 are all arranged in the installation cavity 242. The sensor 26 is the above-mentioned under-screen sensor, the first touch area 12 is the general touch area covering a large area of the mobile phone touch screen, and the second touch area 14 is the touch area opposite to the sensor position. Exemplarily, the sensor can be a front camera, an ultrasonic fingerprint sensor, a face sensor or an ambient light sensor. The presence of the sensor will interfere with the touch panel 10 above it. For this purpose, the present application sets the second touch area 14 opposite to the position where the sensor is located, and sets an independent touch circuit for the second touch area 14 where the under-screen sensor is set, so as to avoid the interference problem caused by the greater noise in the touch area opposite to the under-screen sensor, and reduce the problems of touch line offset and touch jump.

For example, for some mobile phones, in order to obtain a better grip or a more beautiful appearance, the frame 28 design may have a special-shaped part, such as the frame 28 is not a standard rectangle, but has rounded corners, which results in the touch panel 10 at the corner being cut to adapt to the special-shaped frame 28. The noise of the touch circuit of the cut part is different from that of other parts, so this part of the area is set as the second touch area 14, and an independent touch circuit is set for the non-standard shape of the second touch area 14 to avoid the problems of touch line deviation and touch point jump caused by different noise intensity in this part of the touch area.
