[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0022] Please refer to Figure 1 and Figure 2 The present invention provides a touch circuit, including a control module 11, a first signal line L1, and a second signal line L2. The first signal line L1 and the second signal line L2 are both electrically connected to the control module 11, and the first signal line L1 and the second signal line L2 are both used to be electrically connected to the same touch electrode 20. The control module 11 is used to output touch pulse signals to the first signal line L1 and the second signal line L2 at the same time, or the control module 11 is used to output touch pulse signals to the first signal line L1. When the first signal line L1 is damaged, the control module 11 is used to output touch pulse signals to the second signal line L2.

[0023] In one embodiment, please refer to Figure 1 The control module 11 includes a pulse transmitting unit 112 , which is electrically connected to the first signal line L1 and the second signal line L2 . The pulse transmitting unit 112 is configured to output a touch pulse signal to the first signal line L1 and the second signal line L2 simultaneously.

[0024] In the specific implementation, please refer to Figure 1 The control module 11 also includes a processor 111 and a touch detection unit 113. The touch detection unit 113 is electrically connected to the processor 111, the first signal line L1, and the second signal line L2. The processor 111 is also electrically connected to the pulse transmitting unit 112. The touch detection unit 113 is electrically connected to the first signal line L1 and the second signal line L2. The processor 111 controls the pulse transmitting unit 112 to output a touch pulse signal to the touch electrode 20 via the first signal line L1 and the second signal line L2. At the same time, the touch detection unit 113 receives the touch pulse signal and outputs a touch feedback signal to the processor 111. When a touch occurs on the touch electrode 20, the touch electrode 20 forms a self-capacitance with the finger, causing the voltage on the touch electrode 20 to change, thereby causing the touch feedback signal output by the touch detection unit 113 to change. The processor 111 can then determine whether the touch electrode 20 has been touched based on the change in the touch feedback signal. Optionally, the touch detection unit 113 is an AFE circuit.

[0025] By setting the pulse emission unit 112 to be electrically connected to both the first signal line L1 and the second signal line L2, the pulse emission unit 112 is used to output touch pulse signals to the first signal line L1 and the second signal line L2 at the same time. When one of the first signal line L1 and the second signal line L2 is damaged, the control module 11 can still output touch pulse signals to the touch electrode 20 through the other to avoid touch failure, thereby improving the stability of the touch circuit and reducing maintenance costs. The structure of the touch circuit is simple, which is conducive to simplifying the manufacturing process and reducing the number of wiring layers and electronic components, thereby reducing the production cost of the touch circuit, and is also beneficial to improving product yield, product reliability and compatibility.

[0026] In another embodiment, please refer to Figure 2 The control module 11 includes a pulse emitting unit 112, a touch detection unit 113 and a switching unit 114. The pulse emitting unit 112 is electrically connected to the touch detection unit 113, the first signal line L1 and the second signal line L2. The touch detection unit 113 is electrically connected to the first signal line L1 and the second signal line L2. The pulse emitting unit 112 is used to output a touch pulse signal to the first signal line L1 through the switching unit 114. The touch detection unit 113 is used to receive a touch feedback signal from the first signal line L1. The pulse emitting unit 112 is used to output a detection signal to the switching unit 114 according to the touch feedback signal. When the first signal line L1 is damaged, the pulse emitting unit 112 is used to output a touch pulse signal to the second signal line L2 through the switching unit 114.

[0027] In the specific implementation, please refer to Figure 2 The control module 11 also includes a processor 111, which is electrically connected to the touch detection unit 113 and the pulse emission unit 112. The processor 111 controls the pulse emission unit 112 to output a touch pulse signal to the touch electrode 20 through the first signal line L1. At the same time, the touch detection unit 113 receives the touch pulse signal and outputs a touch feedback signal to the processor 111. When a touch occurs on the touch electrode 20, the touch electrode 20 forms a self-capacitance with the finger, causing the voltage on the touch electrode 20 to change, thereby causing the touch feedback signal output by the touch detection unit 113 to change. The processor 111 can determine whether the touch electrode 20 is touched based on the change in the touch feedback signal.

[0028] In the specific implementation, please refer to Figures 2 to 4 The detection signal includes a first detection signal K1 and a second detection signal K2. When the first signal line L1 is functioning normally, the voltage on the first signal line L1 detected by the touch detection unit 113 is within the same numerical range or waveform as the preset voltage V0. The touch detection unit 113 outputs the first detection signal K1 and the second detection signal K2 of the same phase to the switching unit 114. The switching unit 114 is configured to output the touch pulse signal from the pulse transmitting unit 112 to the first signal line L1 based on the first detection signal K1 and the second detection signal K2. When the first signal line L1 is damaged, the voltage on the first signal line L1 detected by the touch detection unit 113 is different from the numerical range or waveform of the preset voltage V0. In this case, the touch detection unit 113 outputs the first detection signal K1 and the second detection signal K2 of opposite phases to the switching unit 114. The switching unit 114 is configured to output the touch pulse signal from the pulse transmitting unit 112 to the second signal line L2 based on the first detection signal K1 and the second detection signal K2.

[0029] Optionally, the process of detecting whether the touch feedback signal meets the preset value may be performed by a computing circuit within the touch detection unit 113 or within the processor 111 , without limitation.

[0030] The control module 11 is configured to include a pulse transmitting unit 112, a touch detection unit 113, and a switching unit 114. The pulse transmitting unit 112 is electrically connected to the touch detection unit 113, the first signal line L1, and the second signal line L2. The touch detection unit 113 is electrically connected to the first signal line L1 and the second signal line L2. The pulse transmitting unit 112 is configured to output a touch pulse signal to the first signal line L1 via the switching unit 114. The touch detection unit 113 is configured to receive a touch feedback signal from the first signal line L1. The pulse transmitting unit 112 is configured to output a detection signal to the switching unit 114 based on the touch feedback signal. When the first signal line L1 is damaged, the pulse transmitting unit 112 is configured to output a touch pulse signal to the second signal line L2 via the switching unit 114. This allows the control module 11 to still output a touch pulse signal to the touch electrode 20 via the second signal line L2 when the first signal line L1 is damaged, thereby avoiding touch failure. This improves the stability of the touch circuit, reduces maintenance costs, and reduces power consumption of the touch circuit.

[0031] In the specific implementation, please refer to Figures 2 to 4 The switching unit 114 includes an XENO gate 1141, a first switch T1, and a second switch T2. The input end of the XENO gate 1141 is electrically connected to the touch detection unit 113, and the output end of the XENO gate 1141 is electrically connected to the control end of the first switch T1 and the control end of the second switch T2. The input end of the first switch T1 and the input end of the second switch T2 are both electrically connected to the pulse emission unit 112. The output end of the first switch T1 is electrically connected to the first signal line L1, and the output end of the second switch T2 is electrically connected to the second signal line L2. The XENO gate 1141 is used to control the first switch T1 or the second switch T2 to open according to the detection signal.

[0032] In the specific implementation, please refer to Figures 2 to 4 The XNOR gate 1141 includes a first input terminal 1142 and a second input terminal 1143. The first input terminal 1142 and the second input terminal 1143 are both electrically connected to the touch detection unit 113. The touch detection unit 113 is used to input the first detection signal K1 to the first input terminal 1142 and to input the second detection signal K2 to the second input terminal 1143. The XNOR gate 1141 is used to output the control signal K3 according to the first detection signal K1 and the second detection signal K2.

[0033] Please refer to Figure 3 and Figure 4 , Figure 3The voltage on the first signal line L1 is a preset voltage V0, the voltage on the first signal line L1 is a first voltage V1, and the voltage on the second signal line L2 is a second voltage V2. In a specific embodiment, the display panel 100 alternates between a display phase t1 and a touch phase t2. When the display panel 100 is in the display phase t1, the pulse emission signal stops outputting the touch pulse signal. At this time, the first voltage V1 and the second voltage V2 are both at a low level, and the touch electrode 20 serves as a common electrode for the pixel 50. When the display panel 100 is in the touch phase t2, the pulse emission signal outputs a touch pulse signal. At this time, if the first signal line L1 is operating normally, the first voltage V1 is a touch pulse signal and the second voltage V2 is at a low level. If the first signal line L1 is not operating normally, the first voltage V1 is at a low level and the second voltage V2 is a touch pulse signal, so that the touch electrode 20 can form a self-capacitance with the finger to achieve the touch function.

[0034] Figure 4 Figure 1 shows the voltage conditions of the first detection signal K1, the second detection signal K2, the control signal K3, the first signal line L1, and the second signal line L2 in the touch control circuit when the first signal line L1 is operating normally or abnormally. A high voltage at the first detection signal K1, the second detection signal K2, the control signal K3, and the first and second signal lines L1 and L2 outputting touch pulse voltages are all represented by "1." A low voltage at the first detection signal K1, the second detection signal K2, the control signal K3, and the first and second signal lines L1 and L2 not outputting touch pulse voltages are all represented by "0."

[0035] When the first detection signal K1 and the second detection signal K2 are both high or low, the XNOR gate 1141 outputs a high-level control signal K3 to the control end of the first switch T1 and the control end of the second switch T2, the first switch T1 is turned on and the second switch T2 is turned off, and the pulse transmitting unit 112 outputs a touch pulse signal to the first signal line L1 through the first switch T1.

[0036] When one of the first detection signal K1 and the second detection signal K2 is at a high level and the other is at a low level, the XNOR gate 1141 outputs a low-level control signal K3 to the control end of the first switch T1 and the control end of the second switch T2, the first switch T1 is closed and the second switch T2 is opened, and the pulse transmitting unit 112 outputs a touch pulse signal to the second signal line L2 through the second switch T2.

[0037] The switching unit 114 is configured to include an XNOR gate 1141, a first switch T1, and a second switch T2. The input end of the XNOR gate 1141 is electrically connected to the touch detection unit 113, and the output end of the XNOR gate 1141 is electrically connected to the control end of the first switch T1 and the control end of the second switch T2. The input end of the first switch T1 and the input end of the second switch T2 are both electrically connected to the pulse emission unit 112. The output end of the first switch T1 is electrically connected to the first signal line L1, and the output end of the second switch T2 is electrically connected to the second signal line L2. The XNOR gate 1141 is configured to control the first switch T1 or the second switch T2 to be turned on based on the detection signal. This allows the switching unit 114 to control the first signal line L1 or the second signal line L2 to output a touch pulse signal based on the detection result of the touch detection unit 113, thereby avoiding touch failure, improving the stability of the touch circuit, and reducing maintenance costs. In addition, the switching unit 114 has a simple structure and can automatically switch when the first signal line L1 is damaged, thereby providing a fast response speed.

[0038] In one embodiment, the first switch T1 is an N-type thin-film transistor, and the second switch T2 is a P-type thin-film transistor. When the XNOR gate 1141 outputs a high level, the first switch T1 is turned on, and the second switch T2 is turned off. When the XNOR gate 1141 outputs a low level, the first switch T1 is turned off, and the second switch T2 is turned on. By setting the first switch T1 as an N-type thin-film transistor and the second switch T2 as a P-type thin-film transistor, the first switch T1 and the second switch T2 can be manufactured simultaneously with other conductive lines or switching elements located on the same metal layer during the patterning etching process, simplifying the manufacturing process and production cost of the switching unit 114, while also helping to reduce the size of the switching unit 114.

[0039] In another embodiment, the first switch T1 is an N-type MOS transistor, and the second switch T2 is a P-type MOS transistor. When the XNOR gate 1141 outputs a high level, the first switch T1 is turned on, and the second switch T2 is turned off. When the XNOR gate 1141 outputs a low level, the first switch T1 is turned off, and the second switch T2 is turned on. By configuring the first switch T1 as an N-type MOS transistor and the second switch T2 as a P-type MOS transistor, the sensitivity and switching power consumption of the first and second switches T1 and T2 are improved, thereby improving the switching speed and accuracy of the switching unit 114.

[0040] The touch circuit is provided to include a control module 11, a first signal line L1, and a second signal line L2. The first signal line L1 and the second signal line L2 are both electrically connected to the control module 11. The first signal line L1 and the second signal line L2 are both used to be electrically connected to the same touch electrode 20. The control module 11 is used to output touch pulse signals to the first signal line L1 and the second signal line L2 at the same time. Alternatively, the control module 11 is used to output touch pulse signals to the first signal line L1. When the first signal line L1 is damaged, the control module 11 is used to output touch pulse signals to the second signal line L2. When one of the first signal line L1 and the second signal line L2 is damaged, the control module 11 can still output touch pulse signals to the touch electrode 20 through the other one to avoid touch failure, thereby improving the stability of the touch circuit and reducing maintenance costs.

[0041] Please refer to Figure 5 The present invention further provides a display panel 100 , including a touch electrode 20 and a touch circuit according to an embodiment of the present invention, wherein the first signal line L1 and the second signal line L2 are both electrically connected to the touch electrode 20 .

[0042] In one embodiment, please refer to Figure 1 and Figure 5 The processor 111 of the touch circuit controls the pulse transmitting unit 112 to output a touch pulse signal to the touch electrode 20 via the first signal line L1 and the second signal line L2. Simultaneously, the touch detection unit 113 receives the touch pulse signal and outputs a touch feedback signal to the processor 111. When a touch occurs on the touch electrode 20, the touch electrode 20 forms a self-capacitance with the finger, causing the voltage on the touch electrode 20 to change, thereby changing the touch feedback signal output by the touch detection unit 113. The processor 111 can then determine whether the touch electrode 20 has been touched based on the change in the touch feedback signal. If one of the first signal line L1 and the second signal line L2 is damaged, the touch circuit in this embodiment of the present invention can still output a touch pulse signal to the touch electrode 20 via the other, thus avoiding touch failure. This improves the stability of the touch circuit and reduces maintenance costs. The touch circuit also has a simple structure, which simplifies the manufacturing process and reduces the number of wiring layers and electronic components, thereby reducing the production cost of the touch circuit and improving product yield, reliability, and compatibility.

[0043] In another embodiment, please refer to Figure 2 and Figure 5The processor 111 controls the pulse transmitting unit 112 to output a touch pulse signal to the touch electrode 20 via the first signal line L1. Simultaneously, the touch detection unit 113 receives the touch pulse signal and outputs a touch feedback signal to the processor 111. When a touch occurs on the touch electrode 20, the touch electrode 20 forms a self-capacitance with the finger, causing the voltage on the touch electrode 20 to change, thereby causing the touch feedback signal output by the touch detection unit 113 to change. The processor 111 can then determine whether the touch electrode 20 has been touched based on the change in the touch feedback signal. When the first signal line L1 is functioning normally, the pulse transmitting unit 112 continues to output the touch pulse signal to the first signal line L1 via the switching unit 114. When the first signal line L1 is damaged, the pulse transmitting unit 112 can output a touch pulse signal to the second signal line L2 via the switching unit 114 to avoid touch failure, thereby improving the stability of the touch circuit, reducing maintenance costs, and lowering the power consumption of the touch circuit.

[0044] In the specific implementation, please refer to the display phase t1 and the touch phase t2. Figure 5 There are multiple touch electrodes 20, each of which is spaced apart. There are multiple first signal lines L1 and second signal lines L2, each of which is connected to one first signal line L1 and one second signal line L2. Optionally, the multiple touch electrodes 20 are arranged in an array of multiple rows and columns, covering the display area of ​​the display panel 100. When a touch occurs, the touch electrode 20 corresponding to the touched location forms a self-capacitance with the finger and outputs a touch feedback signal to the touch detection unit 113 via the first signal line L1 and / or the second signal line L2. The processor 111 then identifies the touched area, completing the touch function.

[0045] In the specific implementation, please refer to Figure 6 The display panel 100 further includes 3N scan lines 30, M data lines 40, and NM pixels 50. The NM pixels 50 are arranged in an array of N rows and M columns.

The M red sub-pixels 51 on the nth row are electrically connected to the 3n-2th scan line 30, the M green sub-pixels 52 on the nth row are electrically connected to the 3n-1th scan line 30, and the M blue sub-pixels 53 on the nth row are electrically connected to the 3nth scan line 30. The red sub-pixel 51, green sub-pixel 52, and blue sub-pixel 53 of each pixel 50 on the mth column are all electrically connected to the mth data line 40. n is a positive integer less than or equal to N, and m is a positive integer less than or equal to M.

[0046] In the specific implementation, please refer to Figure 6The data line 40 is arranged between the red sub-pixel 51 and the green sub-pixel 52 of the corresponding pixel 50, and is also arranged between the green sub-pixel 52 and the blue sub-pixel 53 of the corresponding pixel 50, so that there is no data line 40 occupying space between adjacent pixels 50, thereby improving the aperture ratio of the display panel 100.

The gate driving circuit 60 is used to output a scanning signal to turn on the corresponding sub-pixel 50, and the source driving circuit is used to output a data signal to make the corresponding sub-pixel 50 emit light.

[0048] In the specific implementation, please refer to Figure 6 The source driving circuit and the control module 11 of the touch control circuit are integrated in the touch control driving chip 70 to improve the integration of the display panel 100 .

[0049] In the specific implementation, please refer to Figure 6 and Figure 8 ,in Figure 8 Schematic diagram of high-resolution text display of the display panel 100 of the present invention. The gate drive circuit 60 independently controls the scanning timing of different sub-pixels 50 through different scanning signals, and cooperates with the data signal input by the data line 40 to realize the display update of some sub-pixels 50, thereby improving the aperture ratio and display uniformity of the pixels 50, which is beneficial to reducing the border of the display panel 100 and reducing the production cost of the display panel 100.

[0050] By arranging the red sub-pixel 51, green sub-pixel 52 and blue sub-pixel 53 of each pixel 50 in sequence in the length direction of the scan line 30, the M red sub-pixels 51 on the nth row are electrically connected to the 3n-2th scan line 30, the M green sub-pixels 52 on the nth row are electrically connected to the 3n-1th scan line 30, and the M blue sub-pixels 53 on the nth row are electrically connected to the 3nth scan line 30. The red sub-pixel 51, green sub-pixel 52 and blue sub-pixel 53 of each pixel 50 on the mth column are all electrically connected to the mth data line 40. This achieves that when the three sub-pixels 50 of each pixel 50 share the same data line 40, they can emit light through time-sharing writing, thereby reducing the number of data lines 40 and the power consumption of the data lines 40, and improving the aperture ratio and display uniformity of the pixels 50, which is beneficial to reducing the border of the display panel 100 and reducing the production cost of the display panel 100.

[0051] In the specific implementation, please refer to Figure 6The length direction of each red sub-pixel 51 , the length direction of each green sub-pixel 52 , and the length direction of each blue sub-pixel 53 are all the same as the length direction of the data line 40 .

[0052] Please refer to Figure 7 and Figure 9 , Figure 7 FIG. 1 is a schematic diagram of a display panel 100 according to a comparative example. Figure 9 This is a schematic diagram of the blurred text edges of a display panel 100 for comparison. To enhance text or pattern detail in a displayed image, the display panel 100 typically employs Clear Type technology to control the illumination of corresponding sub-pixels 50 of pixels 50 at corresponding locations. This allows the display hue of the display panel 100 to adjust according to image requirements, thereby increasing the sharpness of minute details in the displayed image and smoothing image edges. To reduce the bezel of the display panel 100 and its production cost, the display panel 100 employs a triple-gate architecture to control the pixels 50. In a conventional triple-gate architecture, the red sub-pixel 51, green sub-pixel 52, and blue sub-pixel 53 of each pixel 50 are arranged vertically, with the sub-pixels 50 arranged horizontally. As a result, even when Clear Type technology controls the illumination of corresponding sub-pixels 50 of pixels 50 at corresponding locations to adjust the display effect, the displayed image still appears relatively rough.

[0053] Therefore, to ensure that the Clear Type technology still has a good image improvement effect under the tri-gate architecture, the display panel 100 provided by the present invention sets the length direction of each red sub-pixel 51, the length direction of each green sub-pixel 52, and the length direction of each blue sub-pixel 53 to be the same as the length direction of the data line 40. This improves the image improvement effect of the Clear Type technology on the display without increasing the power consumption and driving method of the display panel 100. At the same time, it also reduces the gate load of the scanning signal, which is beneficial to lowering the operating temperature of the gate drive circuit 60.

[0054] In the specific implementation, please refer to Figure 5 and Figure 6 There are multiple touch electrodes 20, which are spaced apart. There are multiple first signal lines L1 and second signal lines L2. Each touch electrode 20 is connected to one first signal line L1 and one second signal line L2. A first signal line L1 is provided between the N blue sub-pixels 53 on the mth column and the N red sub-pixels 51 on the m+1th column, and a second signal line L2 is provided between the N blue sub-pixels 53 on the m+1th column and the N red sub-pixels 51 on the m+2th column. The first signal line L1 and the second signal line L2 are provided on both sides of the N pixels 50 on the 1st column, respectively.

[0055] Specifically, the length direction of each red sub-pixel 51, the length direction of each green sub-pixel 52, and the length direction of each blue sub-pixel 53 are all the same as the length direction of the data line 40. The data line 40 is arranged between the red sub-pixel 51 and the green sub-pixel 52 of the corresponding pixel 50, and is also arranged between the green sub-pixel 52 and the blue sub-pixel 53 of the corresponding pixel 50, so that the gap between adjacent pixels 50 is increased, so that the first signal line L1 and the second signal line L2 can be arranged in the gap between adjacent pixels 50, specifically, they can be arranged in the same metal layer as the data line 40, thereby reducing the wiring layer of the display panel 100, which is beneficial to the lightweight and thinness of the display panel 100.
