Description

Display panel, display device, and display panel control method Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel, a display device, and a method for controlling a display panel. Background Art

[0002] In related technologies, with the development of display technology, the application scope of displays is becoming increasingly broad. As displays are used in various life scenarios, people's requirements for displays are also increasing, and higher requirements are being placed on the display's color gamut, viewing angle, contrast, response, and display border width.

[0003] Currently, display panels are equipped with a display signal multiplexer (Display MUX) and a touch signal multiplexer (TP MUX). The Display MUX primarily reduces the number of wiring required to connect the display data lines of each pixel in the display area to the driver chip. Similarly, the Touch MUX primarily reduces the number of wiring required to connect the touch signal lines in the display area to the driver chip.

[0004] However, simply stacking the display signal multiplexer and the touch signal multiplexer on the display panel results in a wider border of the display panel.

[0104] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0105] In related display technologies, referring to the display panel shown in FIG1 , it includes: a substrate 11 ′, a display signal selection circuit 12 ′, a touch signal selection circuit 13 ′, and a light-emitting structure 14 ′. The display signal selection circuit 12 ′, the touch signal selection circuit 13 ′, and the light-emitting structure 14 ′ are all located on the substrate 11 ′, and the display signal selection circuit 12 ′ and the touch signal selection circuit 13 ′ are all electrically connected to the light-emitting structure 14 ′ via wiring. The display signal selection circuit 12 ′ and the touch signal selection circuit 13 ′ are also electrically connected to the driver chip 15 ′ via wiring. The signal emitted by the driver chip 15 ′ is transmitted to the display data line and the touch signal line in the light-emitting structure 14 ′ through the display signal selection circuit 12 ′ and the touch signal selection circuit 13 ′, and then transmitted to the pixel electrode through the display data line, and to the touch electrode through the touch signal line.

[0106] Because the display signal selection circuit 12' and the touch signal selection circuit 13' are simply and compactly disposed on the substrate 11', and there is no structural connection between them, the display panel frame width occupied by the display signal selection circuit 12' and the touch signal selection circuit 13' is relatively wide, i.e., the width W' in FIG1 is relatively wide.

[0107] Simply integrating the display signal selection circuit 12' and the touch signal selection circuit 13' can lead to signal short circuits. This means that the signals transmitted by the two lines will conflict within some shared lines after integration. Therefore, integrating the display signal selection circuit 12' and the touch signal selection circuit 13' to avoid signal short circuits while also reducing the display panel frame area occupied by the integrated circuits has become an urgent issue.

[0108] An embodiment of the present application provides a display panel 10. FIG2 is a schematic diagram of the structure of the display panel 10.

A plurality of sequential selection lines 131 are electrically connected to the gates of the first sequential switches 132 and the second sequential switches 133 to control the opening and closing of the first sequential switches 132 and the second sequential switches 133.

[0112] The display signal selection circuit 110 and the touch signal selection circuit 120 are both electrically connected to the first timing switch 132 and the second timing switch 133 of the timing selection circuit 130. The timing selection circuit 130 is electrically connected to the display data line through the first timing switch 132 and to the touch signal line through the second timing switch 133.

[0113] Specifically, the display data lines are used to transmit the display signals transmitted by the signal selection circuit 12 to the touch display structure 14 of the display panel 10 to realize the display function of the display panel 10, which may include the display data lines R1 / G1 / B1 / R2 / G2 / B2 shown in Figure 3.

[0114] The touch signal lines are used to transmit the touch signals transmitted by the signal selection circuit 12 to the touch display structure 14 of the display panel 10 to implement the touch function of the display panel 10 , and may include the touch signal lines T1 / T2 / T3 / T4 / T5 / T6 in FIG. 3 .

[0115] Furthermore, the display signal selection circuit 110 and the touch signal selection circuit 120 can be electrically connected to the same trace in the timing selection circuit 130 , which, after extension, can be electrically connected to the first timing switch 132 and the second timing switch 133 in the timing selection circuit 130 through two branches, respectively.

[0116] When the display panel 10 is in display mode 101, the first timing switch 132 is turned on and the second timing switch 133 is turned off according to the timing signal transmitted by the sub-timing selection line 131. The display signal transmitted by the display signal selection circuit 110 is transmitted to the display data line through the timing selection circuit 130.

[0117] That is, switches f1 / f2 / f3 / f4 / f5 / f6 are turned on, and switches c1 / c2 / c3 / c4 / c5 / c6 are turned off, thereby forming a circuit from the display signal selection circuit 110 to the display data line to transmit the display signal to the display data line.

[0118] When the display panel 10 is in touch mode 102, the first timing switch 132 is closed and the second timing switch 133 is opened according to the timing signal transmitted by the sub-timing selection line 131. The touch signal transmitted by the touch signal selection circuit 120 is transmitted to the touch signal line through the timing selection circuit 130.

[0119] That is, switches f1 / f2 / f3 / f4 / f5 / f6 are closed, and switches c1 / c2 / c3 / c4 / c5 / c6 are opened, thereby forming a circuit from the touch signal selection circuit 120 to the touch signal line to transmit the touch signal to the touch signal line.

[0120] By introducing the first timing switch 132 and the second timing switch 133 and the corresponding timing selection circuit 130, corresponding signals can be transmitted for different modes of the display panel 10 through multiple timing selection lines 131 to control the opening or closing of the first timing switch 132 and the second timing switch 133, so as to electrically connect the touch signal selection circuit 120 to the touch signal line in different modes of the display panel, or electrically connect the display signal selection circuit 110 to the display data line. Therefore, the integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120 can be realized, and the problem of signal short circuit in the line formed after integration can be avoided by the first timing switch 132 and the second timing switch 133. Furthermore, the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced without affecting the operation of the display panel 10, that is, the width W shown in Figure 2.

[0121] It should be noted that the boundaries of the display signal selection circuit 110, touch signal selection circuit 120, and timing selection circuit 130 shown in FIG3 are merely for the sake of clarity. In practice, in the line diagram, due to the integrated design of the signal selection circuit 12, the lines overlap. For example, some lines of the display signal selection circuit 110 need to pass through the boundaries of the touch signal selection circuit 120, and some lines of the touch signal selection circuit 120 need to pass through the boundaries of the display signal selection circuit 110. These interlaced lines do not affect the boundaries of the display signal selection circuit 110, touch signal selection circuit 120, and timing selection circuit 130. The signal selection circuit 12 shown in the figure can also be referred to in the description here.

[0122] In some embodiments, as shown in FIG. 2 , the display panel 10 includes a substrate 11 , a signal selection circuit 12 , a touch display structure 14 , and a driver chip 15 .

[0123] The signal selection circuit 12, touch display structure 14, and driver chip 15 are all located on the same side of the substrate 11. The driver chip 15 is electrically connected to the signal selection circuit 12 via traces. The signal selection circuit 12 is electrically connected to the display data lines and touch signal lines. The display data lines and touch signal lines are, in turn, electrically connected to the pixel electrodes or touch electrodes within the touch display structure 14. The touch signals or display signals generated by the driver chip 15 are transmitted to the touch signal lines or display data lines via the signal selection circuit 12.

[0124] The touch display structure 14 is the light-emitting area of ​​the display panel 10. The display data lines and the gate data lines together constitute a driver array that drives the touch display structure 14 to emit light. After receiving the display signal transmitted by the display data line, the touch display structure 14 performs different light-emitting functions according to the display signal. Among them, when adopting the liquid crystal display principle, the display signal is applied to the electrodes on both sides of the liquid crystal layer in the touch display structure 14. By forming different electric fields to control the deflection angles of the liquid crystal particles in each part of the liquid crystal layer, the light emitted by the backlight structure of the display panel 10 passes through the liquid crystals with different deflection angles to achieve different light-emitting states. When adopting the self-luminous material display principle, the display signal is applied to different anodes in the touch display structure 14. Each anode is electrically connected to a self-luminous material. The self-luminous material that receives the voltage of the display signal releases energy by forming excitons through the recombination of holes and electrons in its interior to achieve different light-emitting states.

[0125] Furthermore, the surface of the touch display structure 14 is provided with an array of touch electrodes. Depending on their sensing principles, these touch electrodes can include self-capacitive touch electrodes and mutual-capacitive touch electrodes. For mutual-capacitive touch electrodes, each row or column of touch electrodes is electrically connected to the same touch signal line. For self-capacitive touch electrodes, each touch electrode, or every few touch electrodes, is electrically connected to the same touch signal line.

[0126] Among them, for mutual capacitance touch electrodes, the touch signal line is used to transmit touch signals. For self-capacitive touch electrodes, the touch signal line is used to transmit touch signals or compensation signals, and in the same time period, the touch signal line causes the signals transmitted to adjacent touch electrodes to be touch signals and compensation signals respectively. The touch electrode that receives the touch signal is used to generate a touch indication signal when it receives contact with a touch object (such as a hand and a stylus, etc.), and then transmits the touch indication signal to the driver chip 15 through the touch signal line and the signal selection circuit 12. At the same time, the adjacent touch electrodes receive compensation signals to avoid the generation of coupling capacitance between the touch electrodes that receive the touch signal, and the touch electrodes that receive the touch signal affect the recognition of the touch object.

[0127] The substrate 11 may be a flexible substrate, and its material may include, but is not limited to, polyimide (PI) and glass. Currently, the material of the substrate 11 may mainly be glass.

[0128] In some embodiments, as shown in FIG3 , which schematically illustrates the structure of the signal selection circuit 12, and with reference to FIG4 , which illustrates a timing diagram, the touch signal selection circuit 120 includes a touch selector line 121, a plurality of touch detection lines 123, and a plurality of detection switches 124. The display signal selection circuit 110 includes a pixel selector line 111, a plurality of display signal lines 112, and a plurality of display switches 113.

[0129] The touch selector line 121 includes multiple sub-touch selection lines 1210. Each sub-touch selection line 1210 is electrically connected to the gates of multiple detection switches 124 and is used to control the opening or closing of the detection switches 124. The touch detection lines 123 are electrically connected to the timing selection circuit 130 through the corresponding detection switches 124. When the detection switches 124 are turned on, the touch detection lines 123 are electrically connected to the timing selection circuit 130 through the corresponding detection switches 124.

[0130] Specifically, the detection switches 124 include switches h1 / h2 / h3 / h4 / h5 / h6 in Figure 3. The touch selector lines 121 include sub-touch selection lines 1210 for transmitting signals TP1 / TP2 in Figure 3. The touch detection lines 123 include lines for transmitting touch signals A1 / A2 / A3 in Figure 3.

[0131] The pixel selector line 111 includes a plurality of sub-pixel selection lines 1110. Each sub-pixel selection line 1110 is electrically connected to the gates of a plurality of display switches 113 and is used to control the on / off state of the display switches 113. The display signal line 112 is electrically connected to the timing selection circuit 130 via the corresponding display switch 113. When the display switch 113 is on, the display signal line 112 is electrically connected to the timing selection circuit 130 via the corresponding display switch 113.

[0132] Specifically, the display switches 113 include switches g1 / g2 / g3 / g4 / g5 / g6 in Figure 3. The pixel selector lines 111 include the sub-pixel selection lines 1110 for transmitting signals D1 / D2 / D3 in Figure 3. The display signal lines 112 include the lines for transmitting display signals S1 / S2 in Figure 3.

[0133] Taking the partial structure shown in FIG. 3 as an example, when the display panel 10 is in display mode 101, the signal VGH-G transmitted by the first timing selection line 134 is at a high level, and the signal En-Touch transmitted by the second timing selection line 135 is at a low level. Therefore, switches f1 / f2 / f3 are open, while switches c1 / c2 / c3 are closed, and the display signal selection circuit 110 is electrically connected to the timing selection circuit 130. Furthermore, the signals D1 / D2 / D3 transmitted by the multiple sub-pixel selection lines 1110 included in the pixel selector line 111 are sequentially at a high level. By sequentially high levels of the signals D1 / D2 / D3, the corresponding display switches 113 can be controlled to open sequentially, that is, switches g1 / g2 / g3 can be opened sequentially, so that the display signal S1 transmitted by the display signal line 112 passes through the switches g1 / g2 / g3 in different time periods and is transmitted to the display data lines R1 / G2 / B1.

[0134] When the display panel is in touch mode 102, the signal VGH-G transmitted by the first timing selection line 134 is at a low level, and the signal En-Touch transmitted by the second timing selection line 135 is at a high level. Therefore, switches f1 / f2 are closed, while switches c1 / c2 are open, and the touch signal selection circuit 120 is electrically connected to the timing selection circuit 130. In addition, the signals TP1 / TP2 transmitted by the multiple sub-touch selection lines 1210 included in the touch selector line 121 are sequentially at a high level. By sequentially high levels of the signals TP1 / TP2, the corresponding detection switches 124 can be controlled to open sequentially, that is, switches h1 / h2 are opened sequentially, so that the touch signal A1 transmitted by the touch detection line 123 passes through the switches h1 / h2 in different time periods and is transmitted to the touch data lines T1 / T2.

[0135] Through the above configuration, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated. The timing selection circuit 130 can also be used to avoid signal short circuits in the integrated lines. As a result, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0136] In some embodiments, FIG5 shows a schematic diagram of the structure of another signal selection circuit 12. As shown in FIG5 and with reference to the timing diagram shown in FIG4, the touch selector line 121 includes multiple sub-touch selection lines 1210. Each sub-touch selection line 1210 is electrically connected to multiple fourth timing switches 128, and is electrically connected to the gates of the corresponding multiple detection switches 124 through the multiple fourth timing switches 128, and is used to control the opening or closing of the detection switches 124 when the fourth timing switches 128 are turned on. The touch detection line 123 is electrically connected to multiple sixth timing switches 129, and is electrically connected to the sources of the corresponding multiple detection switches 124 through the multiple sixth timing switches 129. The gates of the sixth timing switches 129, the fourth timing switches 128, and the second timing switches 133 receive the same timing signal.

[0137] Specifically, the fourth sequential switch 128 includes switches e1 / e2 / e3 / e4. The sixth sequential switch 129 includes switches b1 / b2 / b3 / b4. The gates of the sixth sequential switch 129, the fourth sequential switch 128, and the second sequential switch 133 can all receive the signal En-Touch.

[0138] The pixel selector line 111 includes a plurality of sub-pixel selection lines 1110. Each sub-pixel selection line 1110 is electrically connected to a plurality of third timing switches 114 and, through the plurality of third timing switches 114, to the gates of the corresponding plurality of display switches 113. Sub-pixel selection lines 1110 are configured to control the on / off switching of the display switches 113 when the third timing switches 114 are on. The display signal line 112 is electrically connected to a plurality of fifth timing switches 115 and, through the plurality of fifth timing switches 115, to the sources of the corresponding plurality of display switches 113. The gates of the fifth timing switches 115, the third timing switches 114, and the first timing switch 132 receive the same timing signal.

[0139] Specifically, the third sequential switch 114 includes switches d1 / d2 / d3 / d4. The sixth sequential switch 129 includes switches a1 / a2 / a3 / a4. The gates of the fifth sequential switch 115, the third sequential switch 114, and the first sequential switch 132 can all receive the signal VGH-G.

[0140] The detection switch 124 and the display switch 113 are multiplexing switches, and the corresponding sub-pixel selection line 1110 and sub-touch selection line 1210 are electrically connected to the gate of the multiplexing switch.

[0141] Taking the partial structure shown in FIG. 4 as an example, when the display panel 10 is in display mode 101, the signal VGH-G transmitted by the first timing selection line 134 is at a high level, and the signal En-Touch transmitted by the second timing selection line 135 is at a low level. Consequently, switches f1 / f2, switches d1 / d2, and switches a1 / a2 are open, while switches c1 / c2, switches e1 / e2, and switches b1 / b2 are closed. This electrically connects the gates of switches h1 / h2 to the corresponding subpixel selection line 1110, and the display signal line 112 to the sources of switches h1 / h2. Furthermore, the signals D1 / D2 transmitted by the multiple subpixel selection lines 1110 included in the pixel selector line 111 are sequentially at a high level. By sequentially high levels of the signals D1 / D2, the corresponding switches h1 / h2 are controlled to open sequentially, allowing the display signal S1 transmitted by the display signal line 112 to pass through the switches h1 / h2 during different time periods and be transmitted to the display data line R1 / B1.

[0142] When the display panel is in touch mode 102, the signal VGH-G transmitted by the first timing selection line 134 is at a low level, and the signal En-Touch transmitted by the second timing selection line 135 is at a high level. Therefore, switches f1 / f2, switches d1 / d2, and switches a1 / a2 are closed, while switches c1 / c2, switches e1 / e2, and switches b1 / b2 are open, electrically connecting the gates of switches h1 / h2 to the corresponding sub-touch selection line 1210, and the touch detection line 123 to the sources of switches h1 / h2. Furthermore, the signals TP1 / TP2 transmitted by the multiple sub-touch selection lines 1210 included in the touch selector line 121 are sequentially at a high level. By sequentially high levels of the signals TP1 / TP2, the corresponding switches h1 / h2 can be controlled to open sequentially, allowing the touch signal A1 transmitted by the touch detection line 123 to pass through the switches h1 / h2 in different time periods and be transmitted to the touch data line T1 / T1.

[0143] Through the above-mentioned configuration, by combining the first timing switch 132 with the display signal selection circuit 110, and combining the second timing switch 133 with the touch signal selection circuit 120, the detection switch 124 and the display switch 113 can be integrated into a multiplexed switch. Thus, the integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120 can be further realized, and the timing selection circuit 130 can be used to avoid the problem of signal short circuit in the line formed after integration. Furthermore, the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced without affecting the operation of the display panel 10, that is, the width W shown in FIG. 2 .

[0144] In some embodiments, based on the fact that the display switch 113 and the detection switch 124 are multiplexed switches, FIG6 shows a schematic diagram of another structure of the signal selection circuit 12, and FIG7 shows a physical diagram of the structure shown in FIG6. As shown in FIG6 and FIG7 and with reference to the timing diagram shown in FIG4, the touch signal selection circuit 120 further includes a compensation selector line 122, a compensation switch 126, and a compensation signal line 125.

[0145] Specifically, since the display switch 113 and the detection switch 124 are multiplexed switches, the compensation switch 126 includes the switches g1 / g2 / g3 / g4 in FIG6 . The compensation selector line 122 includes the compensation selection line 1220 for transmitting the signals VCOM1 / VCOM2 in FIG6 . The compensation signal line 125 includes the line for transmitting the touch signal LFD in FIG6 .

[0146] The compensation selector line 122 includes a plurality of compensation selection lines 1220. Each compensation selection line 1220 is electrically connected to the gates of a plurality of compensation switches 126 and is used to control the opening or closing of the compensation switches 126. The compensation signal line 125 is electrically connected to the timing selection circuit 130 through the plurality of compensation switches 126.

[0147] The timing selection circuit 130 includes a plurality of sub-selection groups 136, each of which is electrically connected to a different display data line and touch data line. The drain of each compensation switch 126 and the drain of the corresponding detection switch 124 are electrically connected to the same sub-selection group 136. The compensation switches 126 and detection switches 124 electrically connected to the same sub-selection group 136 are alternately turned on during the period when the display panel 10 is in the touch mode 102.

[0148] Specifically, taking the partial structure shown in FIG6 as an example, when the second timing switch 133 is on, the first timing switch 132 is off, switches a1 and d1 are off, and the display signal S1 cannot pass through switch a1, nor can the signal D1 pass through switch d1. However, since switch c1 is on and switch f1 is off, the touch signal line T1 is electrically connected to the touch selection circuit 120.

[0149] Signal VCOM1 is transmitted to the gate of switch g1, controlling it. Switch g1 controls whether the compensation signal LFD passes through it. If switch h1 is on, switch g1 is off. If switch h1 is off, switch g1 is on. The compensation signal LFD is transmitted through switch g1 to the timing selection circuit 130 and then to the touch signal line T1 via switch c1. The driving methods for other components of the touch signal selection circuit 120 can be similarly referenced in this section.

[0150] Furthermore, for adjacent touch electrodes or adjacent touch blocks comprising multiple touch electrodes, the touch electrodes or touch blocks receiving compensation signals are used to avoid coupling capacitance between the touch electrodes or touch blocks receiving touch signals, thereby affecting recognition of the touch object.

[0151] Through the above-mentioned arrangement, the touch detection accuracy of the display panel 10 can be improved while achieving the touch function by electrically connecting the touch signal selection circuit 120 to the touch signal line in different modes of the display panel, or the display signal selection circuit 110 can be electrically connected to the display data line to achieve the display function. Thus, the integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120 can be specifically implemented in another manner, and the problem of signal short circuit in the line formed after integration can be avoided by using the first timing switch 132 and the second timing switch 133. Furthermore, in another manner, the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120, i.e., the width W shown in FIG. 2 , can be reduced without affecting the operation of the display panel 10.

[0152] In some embodiments, the detection switch 124 and the display switch 113 are not multiplexed switches. FIG8 shows a schematic diagram of another structure of the signal selection circuit 12, and FIG9 shows a physical diagram of the structure shown in FIG8. As shown in FIG8 and FIG9 and compared with the timing diagram shown in FIG4, the touch signal selection circuit 120 further includes a compensation selector line 122, a compensation switch 126, and a compensation signal line 125.

[0153] The compensation selector lines 122 include a plurality of compensation selection lines 1220. Each compensation selection line 1220 is electrically connected to a plurality of fourth sequential switches 128 and is electrically connected to the gate of a compensation switch 126 via the fourth sequential switches 128. Each compensation selection line 1220 is configured to control the on / off state of the compensation switch 126 when the fourth sequential switch 128 is on. The compensation signal line 125 is electrically connected to a plurality of sixth sequential switches 129 and is electrically connected to the source of the compensation switch 126 via the sixth sequential switches 129. When the sixth sequential switch 129 is on, the compensation signal line 125 is electrically connected to the timing selection circuit 130 via the compensation switch 126. The gates of the sixth sequential switches 129, the fourth sequential switches 128, and the second sequential switch 133 receive the same timing signal.

[0154] Specifically, the fourth sequential switch 128 includes switches e1 / e2 / e3 / e4 / e5 / e6. The sixth sequential switch 129 includes switches b1 / b2 / b3 / b4 / b5 / b6. The gates of the sixth sequential switch 129, the fourth sequential switch 128, and the second sequential switch 133 can all receive the signal En-Touch.

[0155] The pixel selector line 111 includes a plurality of sub-pixel selection lines 1110. Each sub-pixel selection line 1110 is electrically connected to a plurality of third timing switches 114 and, through the plurality of third timing switches 114, to the gates of the corresponding plurality of display switches 113. Sub-pixel selection lines 1110 are configured to control the on / off switching of the display switches 113 when the third timing switches 114 are on. The display signal line 112 is electrically connected to a plurality of fifth timing switches 115 and, through the plurality of fifth timing switches 115, to the sources of the corresponding plurality of display switches 113. The gates of the fifth timing switches 115, the third timing switches 114, and the first timing switch 132 receive the same timing signal.

[0156] Specifically, the third sequential switch 114 includes switches d1 / d2 / d3 / d4 / d5 / d6. The sixth sequential switch 129 includes switches a1 / a2 / a3 / a4 / a5 / a6. The gates of the fifth sequential switch 115, the third sequential switch 114, and the first sequential switch 132 can all receive the signal VGH-G.

[0157] The compensation switch 126 and the display switch 113 are multiplexing switches, and the corresponding sub-pixel selection line 1110 and the compensation selection line 1220 are electrically connected to the gate of the multiplexing switch.

[0158] Specifically, since the display switch 113 and the detection switch 124 are multiplexed switches, both the display switch 113 and the compensation switch 126 include the switches g1 / g2 / g3 / g4 shown in FIG6 . The compensation selector lines 122 include the compensation selection lines 1220 shown in FIG6 for transmitting the signals VCOM1 / VCOM2. The compensation signal lines 125 include the lines shown in FIG6 for transmitting the touch signal LFD.

[0159] The timing selection circuit 130 includes a plurality of sub-selection groups 136, each of which is electrically connected to a different display data line and touch data line. The drain of each compensation switch 126 and the drain of the corresponding detection switch 124 are electrically connected to the same sub-selection group 136. The compensation switches 126 and detection switches 124 connected to the same sub-selection group 136 are alternately turned on when the display panel 10 is in the touch mode 102.

[0160] Taking the partial structure shown in FIG8 as an example, when the second timing switch 133 is on, the first timing switch 132 is off, switches a1 and d1 are off, and the display signal S1 cannot pass through switch a1, nor can the signal D1 pass through switch d1. However, since switch c1 is on and switch f1 is off, the touch signal line T1 is electrically connected to the touch selection circuit 120.

[0161] Furthermore, when the second timing switch 133 is turned on, switches b1 and e1 are turned on. After passing through switch e1, signal VCOM1 is transmitted to the gate of switch g1, controlling switch g1. Switch g1 controls whether the compensation signal LFD passes through switch g1. If switch h1 is turned on, switch g1 is turned off, and touch signal A1 is transmitted to the timing selection circuit 130 via switch h1 and to the touch signal line T1 via switch c1. If switch h1 is turned off, switch g1 is turned on, and compensation signal LFD is transmitted to the timing selection circuit 130 via switch g1 and to the touch signal line T1 via switch c1. The driving methods of other components of the touch signal selection circuit 120 can be referred to in this section.

[0162] When the second timing switch 133 is off, the first timing switch 132 is on, switches b1 and e1 are off, and switch h1 is also off. The compensation signal LFD cannot pass through switch b1, and the signal VCOM1 cannot pass through switch e1. Since switch c1 is off and switch f1 is on, the display data line R1 receives the display signal S1, and the touch signal line T1 does not receive the compensation signal LFD or the touch signal A1.

[0163] At the same time, the first timing switch 132 is turned on, and switches a1 and d1 are turned on. Signal D1 is transmitted to the gate of switch g1, controlling switch g1. Switch g1 controls whether display signal S1 passes through switch g1. If it passes through switch g1, display signal S1 is transmitted to display data line R1 via switch f1. The driving methods of other components of display signal selection circuit 110 can be similarly referenced in this section.

[0164] Through the above-mentioned arrangement, it is possible to electrically connect the touch signal selection circuit 120 to the touch signal line in different modes of the display panel to realize the touch function, or to electrically connect the display signal selection circuit 110 to the display data line to realize the display function. Thus, it is possible to specifically realize the integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120, and avoid the problem of signal short circuit in the line formed after the integration by the first timing switch 132 and the second timing switch 133. Furthermore, it is possible to reduce the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120, that is, the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0165] It should be noted that the line diagrams shown in other embodiments of the present application can also refer to the timing diagram shown in FIG4 .

[0166] In some embodiments, as shown in the timing diagram of FIG4 , during the time period when the display panel 10 is in display mode 101, the signal CK and the signal CKB are successively high. Among them, the signals CK / CKB are both clock signals and are used to sequentially control different gate drive units (GOA) to output gate drive signals. When the signal CK controls the gate line of the Nth row to open, the display signal is sequentially provided to different display data lines when the gate line is opened. At the same time, the signal CKB controls the gate line of the N+1th row to open, and the display signal is sequentially provided to different display data lines when the gate line is opened. When the gate line is opened, if the sub-pixel electrically connected to the gate line receives the display signal transmitted by the display data line at the same time, it can be controlled to perform the light-emitting function.

[0167] It should be noted that simultaneously setting the CK and CKB signals is only one possible embodiment, but is not limited thereto in other embodiments. Alternatively, only one CK signal may be set. By alternately scanning different gate lines with the CK and CKB signals, the threshold drift problem of the drive transistors within the display panel 10 can be avoided.

[0168] Furthermore, in the timing diagram shown in FIG. 4 , signals TP1 / TP2 / VCOM1 / VCOM2, compensation signal LFD, and touch signal A all include a co-frequency level during the time period when the display panel 10 is in touch mode 102. This co-frequency level is higher than the low level but lower than the high level. Furthermore, the co-frequency levels included in these signals not only have the same frequency intervals but also correspond to each other and remain synchronized within the time period. Specifically, signals TP1 and VCOM2 do not need to have their co-frequency levels increased during the first time period 1021, and signals TP2 and VCOM1 do not need to have their co-frequency levels increased during the second time period 1022. Instead, these signals can be gate-controlled to maintain a high level within the corresponding time periods.

[0169] By adding a co-frequency level to each of the aforementioned signals, the co-frequency level ensures that the frequency of the touch signal A remains synchronized with the frequencies of the aforementioned other signals during the period when the display panel 10 is in the touch mode 102. This prevents the frequencies of the aforementioned other signals from being out of sync with the touch signal A, which could cause abnormal capacitance fluctuations in the touch electrodes. Specifically, this prevents the situation where, when the touch signal A transmitted via the touch data line is in a low frequency range, the electromagnetic fields generated by the other signals, which are not synchronized with the touch signal A but are in a high frequency range, interfere with the capacitance of the touch electrodes. This prevents the detection accuracy of the touch signal A from being affected.

[0170] It should be noted that the concept of co-frequency level is introduced above for the sake of convenience. In fact, the co-frequency level in the signal other than the aforementioned touch signal A is the touch signal A doped in the signal, and the co-frequency level itself is the frequency of the touch signal A.

[0171] It should also be noted that the signals D1 / D2 / D3 shown in Figure 4 are in the order of D1 to D2 to D3 to D3 to D2 to D1 for one cycle, but in other embodiments it is not limited to this. For example, the signals D1 / D2 / D3 can also be in the order of D1 to D2 to D3 to D1 to D2 to D3 for one cycle.

[0172] In some embodiments, FIG10 illustrates another structural division of the signal selection circuit 12 in FIG8 . As shown in FIG8 and FIG10 and compared with the timing diagram in FIG4 , the display panel 10 further includes: a plurality of touch drive units 310 . The plurality of touch drive units 310 are electrically connected to the same compensation selector line 122 , the same touch selector line 121 , and the same compensation signal line 125 .

[0173] Each touch drive unit 310 includes at least two sub-touch drive groups 311, each of which is electrically connected to at least two adjacent touch signal lines. Each of the at least two sub-touch drive groups 311 includes two second timing switches 133, a detection switch 124, and a display switch 113. Since the display switch 113 and the compensation switch 126 are multiplexed switches, the display switch 113 can also be described as the compensation switch 126. The at least two sub-touch drive groups 311 within the same touch drive unit 310 share the same touch detection line 123, which is electrically connected to the two detection switches 124.

[0174] Taking the content shown in FIG. 10 as an example, switches b1 / b2, switches e1 / e2, switches g1 / g2, and switches h1 / h2 belong to the same touch drive unit 310. Furthermore, switches b1, e1, g1, and h1 belong to one sub-touch drive group 311 within the touch drive unit 310, and switches b2, e2, g2, and h2 belong to another sub-touch drive group 311 within the touch drive unit 310. The two sub-touch drive groups 311 share the same touch detection line 123.

[0175] Furthermore, each touch drive unit 310 may include two sub-touch drive groups 311, and the two sub-touch drive groups 311 are electrically connected to two adjacent touch signal lines respectively; or, each touch drive unit 310 may include three sub-touch drive groups 311, and the three sub-touch drive groups 311 are electrically connected to three adjacent touch signal lines respectively; or, each touch drive unit 310 may include four sub-touch drive groups 311, and the four sub-touch drive groups 311 are electrically connected to four adjacent touch signal lines respectively; or, each touch drive unit 310 may include five sub-touch drive groups 311, and the five sub-touch drive groups 311 are electrically connected to five adjacent touch signal lines respectively, but is not limited thereto.

[0176] The solution in which each touch drive unit 310 includes three sub-touch drive groups 311 can be referred to the structural schematic diagram of another signal selection circuit 12 shown in FIG22 , and the physical diagram of the line integration solution shown in FIG22 shown in FIG23 . Furthermore, the solution in which each touch drive unit 310 includes more sub-touch drive groups 311 can be similarly deduced.

[0177] It should be noted that the above division method of the touch driving unit 310 is to further clarify the driving method of the touch signal selection circuit 120 . Therefore, this division method does not conflict with the above description of the signal selection circuit 12 .

[0178] The at least two sub-touch driving groups of each touch driving unit are electrically connected to the at least two sub-touch selection lines 1210 , and are electrically connected to the at least two compensation selection lines 1220 .

[0179] When the display panel 10 is in the touch mode 102, in the first time period 1021, one touch sub-drive group is electrically connected to the touch detection line 123, and the other touch sub-drive group is electrically connected to the compensation signal line 125. In the second time period 1022, the electrical connection targets of the two touch sub-drive groups are swapped.

[0180] Specifically, using the partial structure of Figure 8 as an example, during the first time period 1021 corresponding to the touch mode 102 shown in Figure 4 , signal TP1 is high, signal TP2 is low, signal VCOM1 is low, and signal VCOM2 is high. Therefore, during the first time period 1021, switch h1 is open, switch h2 is closed, switch g1 is closed, and switch g2 is open. At this time, touch signal A1 passes through switch h1 to touch signal line T1. Simultaneously, compensation signal LFD passes through switch g2 to touch signal line T2.

[0181] At this time, the touch signal line T1 to which the touch signal A1 is applied is used to detect the touching object. The compensation signal LFD applied to the touch signal line T2 is used to prevent it from forming a coupling capacitor with the adjacent touch signal line to which the touch signal A1 is applied, thereby preventing the formation of a coupling capacitor that would affect the detection of the touch signal line to which the touch signal A1 is applied.

[0182] During the second time period 1022 of the touch mode 102, signal TP1 is at a low level, signal TP2 is at a high level, signal VCOM1 is at a high level, and signal VCOM2 is at a low level. Therefore, during the second time period 1022, switch h1 is closed, switch h2 is open, switch g1 is open, and switch g2 is closed. At this time, touch signal A1 passes through switch h2 to touch signal line T2. Simultaneously, compensation signal LFD passes through switch g1 to touch signal line T1.

[0183] By alternately applying the compensation signal LFD and the touch signal A1 to adjacent touch signal lines in the first time period 1021 and the second time period 1022 , the display panel 10 can detect the touch signal.

[0184] Through the above configuration, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated. The first timing switch 132 and the second timing switch 133 can also be used to avoid signal short circuits in the integrated lines. As a result, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0185] It should be noted that, due to the limitations of the specifications of the driver chip 15 , this embodiment employs a design in which each touch driver unit includes two touch driver groups, and the two touch driver groups share the same touch detection line 123 . However, the present invention is not limited thereto. Depending on the improvement in the specifications of the driver chip 15 , a design in which one touch driver unit includes more touch driver groups may also be employed.

[0186] In some embodiments, FIG11 illustrates another structural division of the signal selection circuit 12 in FIG8 . As shown in FIG8 and FIG11 and compared with the timing diagram in FIG4 , the display panel 10 further includes: a plurality of display driver units 210 . The plurality of display driver units 210 are electrically connected to the same pixel selector line 111 . Each pixel driver unit 210 is electrically connected to a display signal line 112 .

[0187] Each display driver unit 210 includes at least two sub-display driver groups 211. Each of the at least two sub-display driver groups 211 includes at least two first timing switches 132 and one display switch 113. Since the display switch 113 and the compensation switch 126 are multiplexed switches, the display switch 113 herein can also be described as the compensation switch 126. The pixel selector lines 111 include at least two sub-pixel selection lines 1110. The at least two sub-display driver groups 211 of each display driver unit 210 are electrically connected to the at least two sub-pixel selection lines 1110, respectively.

[0188] Specifically, the pixel selector line 111 includes at least two sub-pixel selection lines 1110, that is, the pixel selector line 111 may include two sub-pixel selection lines 1110, or, the pixel selector line 111 may include three sub-pixel selection lines 1110, or, the pixel selector line 111 may include four sub-pixel selection lines 1110, or, the pixel selector line 111 may include five sub-pixel selection lines 1110, but is not limited thereto.

[0189] It should be noted that the above division method of the display driving unit 210 is to further clarify the driving method of the display signal selection circuit 110 . Therefore, the division method does not conflict with the above description of the signal selection circuit 12 .

[0190] At least two sub-pixel select lines 1110 are electrically connected to at least two corresponding display switches 113 through at least two first timing switches 132 located within the same display driver unit 210. The display signal line 112 is divided into at least two display signal branches 1121. The at least two display signal branches 1121 are electrically connected to at least two corresponding display switches 113 through at least two other first timing switches 132 located within the same display driver unit 210, and are electrically connected to at least two corresponding display data lines through the display switches 113. When the display panel 10 is in display mode, the first timing switches 132 are turned on, and display signals are transmitted to the display data lines.

[0191] Specifically, taking the partial structure of FIG. 3 as an example, during the time period corresponding to display mode 101 shown in FIG. 4 , signal VGH-G is high, signal En-Touch is low, and switches a1 / d1 / a2 / d2 / a3 / d3 within the same display driver unit 210 are open. Signals D1 / D2 / D3 transmitted by pixel selector line 111 are connected to the gates of switches g1 / g2 / g3 to control the opening or closing of switches g1 / g2 / g3. Furthermore, during the time period of display mode 101, signals D1 / D2 / D3 are high during different time periods.

[0192] When the signal D1 is at a high level, the switch g1 is turned on, and the signal S1 transmitted by the display signal line 112 passes through a display signal branch 1121, switches a1, and is transmitted to the display data line R1 through the turned-on switch g1.

[0193] When the signal D2 is at a high level, the switch g2 is turned on, and the signal S1 transmitted by the display signal line 112 passes through a display signal branch 1121, switches a2, and is transmitted to the display data line G2 through the turned-on switch g2.

[0194] When the signal D3 is at a high level, the switch g3 is turned on, and the signal S1 transmitted by the display signal line 112 passes through a display signal branch 1121, switches a3, and is transmitted to the display data line B1 through the turned-on switch g3.

[0195] Through the above configuration, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated. The first timing switch 132 and the second timing switch 133 can also be used to avoid signal short circuits in the integrated lines. As a result, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0196] Based on the aforementioned arrangement of the display driver unit 210, in some embodiments, FIG12 shows a schematic diagram of the structure of another signal selection circuit 12. FIG13 shows a physical diagram of the line integration scheme shown in FIG12. As shown in FIG12 and FIG13, the pixel selector line 111 includes two sub-pixel selection lines 1110. The display driver unit 210 includes four first timing switches 132 and two display switches 113. That is, the display driver unit 210

[0197] The two sub-pixel select lines 1110 are electrically connected to the two display switches 113, respectively, through two first timing switches 132 located within the same display driver unit 210. The display signal line 112 is divided into two display signal branches 1121. The two display signal branches 1121 are electrically connected to the two display switches 113, respectively, through two other first timing switches 132 located within the same display driver unit 210. After passing through the display switches 113, they are electrically connected to the two display data lines. When the display panel 10 is in display mode, the first timing switches 132 are turned on, and the display signals are transmitted to the display data lines.

[0198] That is, in this embodiment, the display signal line 112 is divided into two display signal branches 1121, and the two display signal branches 1121 originating from the same display signal line 112 are electrically connected to the two display data lines through the two sub-display driving groups 211 in the display driving unit 210 electrically connected to the display signal line 112. Thus, the signal S1 or the signal S2 transmitted by the display signal line 112 in different time periods is transmitted to the two display data lines respectively, thereby realizing the display function of the display panel 10.

[0199] Through the above configuration, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated. The first timing switch 132 and the second timing switch 133 can also be used to avoid signal short circuits in the integrated lines. As a result, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0200] Based on the aforementioned configuration scheme of the display driver unit 210, in some embodiments, FIG8 further illustrates a schematic structural diagram of a signal selection circuit 12. FIG9 illustrates a physical diagram of the line integration scheme shown in FIG8 . As shown in FIG8 and FIG9 , the pixel selector line 111 includes three sub-pixel selection lines 1110. The display driver unit 210 includes six of the first timing switches 132 and three display switches 113.

[0201] The three sub-pixel select lines 1110 are electrically connected to the three display switches 113 through the three first timing switches 132 located within the same display driver unit 210. The display signal line 112 is divided into three display signal branches 1121. The three display signal branches 1121 are electrically connected to the three display switches 113 through the other three first timing switches 132 located within the same display driver unit 210. After passing through the display switches 113, they are electrically connected to the three display data lines. When the display panel 10 is in display mode, the first timing switches 132 are turned on, and the display signals are transmitted to the display data lines.

[0202] That is, in this embodiment, the display signal line 112 is divided into three display signal branches 1121, and the three display signal branches 1121 originating from the same display signal line 112 are electrically connected to the three display data lines through the three sub-display driving groups 211 in the display driving unit 210 electrically connected to the display signal line 112. Thus, the signal S1 or the signal S2 transmitted by the display signal line 112 in different time periods is transmitted to the three display data lines respectively, thereby realizing the display function of the display panel 10.

[0203] Through the above configuration, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated. The first timing switch 132 and the second timing switch 133 can also be used to avoid signal short circuits in the integrated lines. As a result, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0204] Based on the aforementioned display driver unit 210 configuration, in some embodiments, FIG14 illustrates a schematic diagram of another structure of the signal selection circuit 12. FIG15 illustrates a physical diagram of the line integration solution shown in FIG14 . As shown in FIG14 and FIG15 , the pixel selector line 111 includes four sub-pixel selection lines 1110. The display driver unit 210 includes eight first timing switches 132 and four display switches 113.

[0205] The four sub-pixel select lines 1110 are electrically connected to the four display switches 113 through four first timing switches 132 within the same display driver unit 210. The display signal line 112 is divided into four display signal branches 1121. The four display signal branches 1121 are electrically connected to the four display switches 113 through four other first timing switches 132 within the same display driver unit 210. After passing through the display switches 113, they are electrically connected to the four display data lines. When the display panel 10 is in display mode, the first timing switches 132 are turned on, and the display signals are transmitted to the display data lines.

[0206] That is, in this embodiment, the display signal line 112 is divided into four display signal branches 1121, and the four display signal branches 1121 originating from the same display signal line 112 are electrically connected to the four display data lines through the four sub-display driving groups 211 in the display driving unit 210 electrically connected to the display signal line 112. Thus, the signal S1 or the signal S2 transmitted by the display signal line 112 in different time periods is transmitted to the four display data lines respectively, thereby realizing the display function of the display panel 10.

[0207] Through the above configuration, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated. The first timing switch 132 and the second timing switch 133 can also be used to avoid signal short circuits in the integrated lines. As a result, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0208] Based on the aforementioned display driver unit 210 configuration, in some embodiments, FIG16 illustrates a schematic diagram of another structure of the signal selection circuit 12. FIG17 illustrates a physical diagram of the line integration solution shown in FIG16. As shown in FIG16 and FIG17, the pixel selector line 111 includes five sub-pixel selection lines 1110. The display driver unit 210 includes ten first timing switches 132 and five display switches 113.

[0209] The five sub-pixel select lines 111 are electrically connected to the five display switches 113 through five first timing switches 132 within the same display driver unit 210. The display signal line 112 is divided into five display signal branches 1121. The five display signal branches 1121 are electrically connected to the five display switches 113 through another five first timing switches 132 within the same display driver unit 210. After passing through the display switches 113, they are electrically connected to the five display data lines. When the display panel 10 is in display mode, the first timing switches 132 are turned on, and the display signals are transmitted to the display data lines.

[0210] That is, in this embodiment, the display signal line 112 is divided into five display signal branches 1121, and the five display signal branches 1121 originating from the same display signal line 112 are electrically connected to the five display data lines through the five sub-display driving groups 211 in the display driving unit 210 electrically connected to the display signal line 112. Therefore, the signal S1 or the signal S2 transmitted by the display signal line 112 in different time periods is transmitted to the five display data lines respectively, thereby realizing the display function of the display panel 10.

[0211] Through the above configuration, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated. The first timing switch 132 and the second timing switch 133 can also be used to avoid signal short circuits in the integrated lines. As a result, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0212] Based on the aforementioned display driver unit 210 configuration, in some embodiments, FIG18 illustrates a schematic diagram of another structure of the signal selection circuit 12. FIG19 illustrates a physical diagram of the line integration solution shown in FIG18. As shown in FIG18 and FIG19, the pixel selector line 111 includes six sub-pixel selection lines 1110. The display driver unit 210 includes twelve first timing switches 132 and six display switches 113.

[0213] The six sub-pixel select lines 1110 are electrically connected to the six display switches 113 through six first timing switches 132 within the same display driver unit 210. The display signal line 112 is divided into six display signal branches 1121. The six display signal branches 1121 are electrically connected to the six display switches 113 through another six first timing switches 132 within the same display driver unit 210. After passing through the display switches 113, they are electrically connected to the six display data lines. When the display panel 10 is in display mode, the first timing switches 132 are turned on, and the display signals are transmitted to the display data lines.

[0214] That is, in this embodiment, the display signal line 112 is divided into six display signal branches 1121, and the six display signal branches 1121 originating from the same display signal line 112 are electrically connected to the six display data lines through the six sub-display driving groups 211 in the display driving unit 210 electrically connected to the display signal line 112. Therefore, the signal S1 or the signal S2 transmitted by the display signal line 112 in different time periods is transmitted to the six display data lines respectively, thereby realizing the display function of the display panel 10.

[0215] Through the above configuration, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated. The first timing switch 132 and the second timing switch 133 can also be used to avoid signal short circuits in the integrated lines. As a result, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0216] In some embodiments, FIG20 shows a line diagram of another specific line integration solution. FIG21 shows a physical diagram of the line integration solution shown in FIG20. As shown in FIG20 and FIG21, the touch signal selection circuit 120 further includes: a plurality of precision switches 127.

[0217] Each detection switch 124 is connected in parallel with at least one precision switch 127 . The gate of each precision switch 127 and the gate of the corresponding detection switch 124 connected in parallel are electrically connected to the same sub-touch selection line 1210 .

[0218] Specifically, as shown in FIG18 , precision switch 127 is connected in parallel with detection switch 124. Specifically, the source and drain of precision switch 127 are electrically connected to the detection switch 124, and the source and drain of precision switch 127 and detection switch 124 are connected to the line. For example, switch h1 is electrically connected to the source and drain of switch k1, and switch h2 is electrically connected to the source and drain of switch k2.

[0219] Furthermore, each detection switch 124 can be connected in parallel with one precision switch 127 , or each detection switch 124 can be connected in parallel with two precision switches 127 , or each detection switch 124 can be connected in parallel with three precision switches 127 , or each detection switch 124 can be connected in parallel with four precision switches 127 , but is not limited thereto.

[0220] When the signal TP1 / TP2 transmitted by the sub-touch select line 1210 is transmitted to the detection switch 124 and the corresponding precision switch 127 connected in parallel therewith, the detection switch 124 and the corresponding precision switch 127 connected in parallel therewith are simultaneously turned on. When the current of the touch signal A1 / A2 passes through the parallel detection switch 124 and the precision switch 127, the load in the detection switch 124 and the precision switch 127 that blocks the current is equivalent to a resistor. In this case, the parallel connection of the resistors can reduce the total resistance of the parallel resistors, that is, reduce the resistance encountered by the current when passing through the parallel detection switch 124 and the precision switch 127. Therefore, the loss of the touch signal A1 / A2 when passing through the detection switch 124 can be reduced, thereby improving the accuracy of touch detection.

[0221] In some embodiments, as shown in Figures 3 and 5 to 23, two adjacent display driver units 210 are alternately electrically connected to the display data lines. The display driver units 210 are configured to alternately transmit positive voltage signals and negative voltage signals in different time periods, and the signals transmitted by the two adjacent display driver units 210 in the same time period are opposite.

[0222] 3 and FIG. 16 of FIG. 5 to FIG. 23 , the display panel 10 includes display data lines R1 / G1 / B1 / R2 / G2 / B2 / R3 / G3 / B3. The display data lines are used to control sub-pixels arranged in rows, columns, or other possible directions within the touch display structure 14.

[0223] When display data lines are used for sub-pixels arranged in the column direction, each display data line is used to control the sub-pixels in the same column, and the sub-pixels in the same column emit the same color of light. For example, the sub-pixels in the columns controlled by display data lines R1 / R2 / R3 are all configured to emit red light, the sub-pixels in the columns controlled by display data lines G1 / G2 / G3 are all configured to emit green light, and the sub-pixels in the columns controlled by display data lines B1 / B2 / B3 are all configured to emit blue light.

[0224] Two adjacent display driver units 210 are alternately electrically connected to the display data lines. For example, the two display driver units 210 used to transmit signal S1 and signal S2, respectively, are configured such that the display driver unit 210 used to transmit signal S1 is electrically connected to display data lines R1 / B1 / G2 / R3 / B3, and the display driver unit 210 used to transmit signal S2 is electrically connected to display data lines G1 / R2 / B2 / G3 / R4. Furthermore, as shown in the various figures, alternate electrical connection of two adjacent display driver units 210 to the display data lines can be achieved by, for example, branching a display signal line 112 into multiple display signal branches 1121 that are electrically connected to corresponding display data lines, as shown in FIG13 . Alternatively, alternate electrical connection of the first timing switch 132 before the display signal enters the display data line can be achieved by staggering the connection, as shown in FIG8 .

[0225] By alternately transmitting positive voltage signals and negative voltage signals in different time periods through the display driving unit 210, and transmitting opposite signals in the same time period by two adjacent display driving units 210, the luminous conditions of sub-pixels in different columns or rows can be changed, thereby refreshing the display content of the display panel 10.

[0226] Therefore, the display signal selection circuit 110 and the touch signal selection circuit 120 can be integrated, and the display content of the display panel 10 can be refreshed while avoiding the problem of signal short circuit in the integrated line through the first timing switch 132 and the second timing switch 133.

[0227] In some embodiments, as shown in FIG. 2 , the display panel 10 further includes a liquid crystal structure and a supplementary power source 13 .

[0228] The liquid crystal structure includes multiple common electrodes 1401, multiple pixel electrodes, and a liquid crystal layer. The common electrodes and the pixel electrodes are located on the same side of the liquid crystal layer. The pixel electrodes are electrically connected to the display data lines, and the common electrodes 1401 are electrically connected to the touch data lines. One common electrode 1401 is multiplexed into a touch electrode, and each touch electrode is electrically connected to at least one touch data line. The display panel 10 includes multiple common electrodes 1401 arranged in an array. The liquid crystal structure is located within the touch display structure 14 shown in FIG. 2 .

[0229] Referring to the electrical connection diagram of the common electrode 1401 and the supplementary power supply 13 shown in Figure 24, the supplementary power supply 13 is electrically connected to the common electrode 1401 and is used to provide a supplementary voltage to the common electrode 1401 during the time period when the display panel 10 is in the display mode 101.

[0230] In a typical solution, when the display panel 10 is in display mode 101, the touch signal selection circuit 120 is at a high level and provides a voltage to a common electrode 1401 electrically connected to the touch signal selection circuit 120. Simultaneously, the display data lines provide different voltages to different pixel electrodes based on different display signals, generating an electric field between the common electrode 1401 and the pixel electrodes. This electric field controls the deflection of liquid crystal molecules within the liquid crystal layer. Light emitted by the backlight within the touch display structure 14 passes through liquid crystal particles in different deflection states, emitting light of varying brightness. This light then passes through the color filter layer within the touch display structure 14, causing the touch display structure 14 to emit different colors.

[0231] After the display signal selection circuit 110 and the touch signal selection circuit 120 are integrated, the touch signal selection circuit 120 needs to maintain a low voltage level when the display panel 10 is in the display mode 101. Therefore, a supplementary power supply 13 electrically connected to the common electrode 1401 is provided to provide a supplementary voltage to the common electrode 1401 during the period when the display panel 10 is in the display mode 101. This compensates for the inability of the touch signal selection circuit 120 to apply a voltage to the common electrode 1401 during this period, thereby preventing the normal display of the display panel 10 from being affected.

[0232] It should be noted that the supplementary power supply 13 has a simple structure and can be made very small. Therefore, the addition of the supplementary power supply 13 will not affect the effect of reducing the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 .

[0233] In some embodiments, as shown in Figures 2 and 24 , the supplemental power source 13 includes a first supplemental power source 1301 and a second supplemental power source 1302. The first supplemental power source 1301 and the second supplemental power source 1302 are located on either side of the liquid crystal structure. For example, Figure 2 illustrates a solution in which the first supplemental power source 1301 and the second supplemental power source 1302 are located on the upper and lower sides of the liquid crystal structure within the touch display structure 14. However, this is not limiting. The first supplemental power source 1301 and the second supplemental power source 1302 may also be located on either side of the liquid crystal structure in other directions.

[0234] The first supplementary power source 1301 includes a plurality of first sub-power sources 1303 , and the second supplementary power source 1302 includes a plurality of second sub-power sources 1304 . Each first sub-power source 1303 is electrically connected to two second sub-power sources 1304 and to a common electrode 1401 .

[0235] That is, each first sub-power source 1303 is electrically connected to two second sub-power sources 1304 , and the traces connecting the first sub-power source 1303 to the two second sub-power sources 1304 are also electrically connected to the two common electrodes 1401 .

[0236] Furthermore, referring to FIG. 25 , which shows the electrical connection lines corresponding to the first sub-power supply 1303, the second sub-power supply 1304, and the common electrode 1401, and FIG. 26 , which shows the timing diagram corresponding to FIG. 25 , during the period when the display panel 10 is in display mode 101, the SW / SW-OE signals are high, and the three signals CTD-Vcom / CTD-Vcom-O / CTD-Vcom-E are used to apply a supplementary voltage to the common electrode 1401. This applies a supplementary voltage to the common electrode 1401, forming an electric field with the pixel electrode to control the deflection state of the liquid crystal particles in the liquid crystal layer. During the period when the display panel 10 is in touch mode 102, the SW / SW-OE signals are low to avoid affecting the detection of changes in the touch indication signal.

[0237] Meanwhile, the first sub-power supply 1303 comprises two parts, namely, the first part 13031 and the second part 13032 shown in Figure 23 . The first part 13031 can be used during initial product design to detect problems such as short circuits between lines. Referring to the timing sequence shown in Figure 26 , during detection, signal CTD-Vcom-O provides a 5V voltage, and signal CTD-Vcom-E provides a supplementary voltage. Voltages are simultaneously applied to the pixel electrodes. At this point, the liquid crystal corresponding to the common electrode 1401 to which signal CTD-Vcom-O is applied deflects, displaying white. The liquid crystal corresponding to the common electrode 1401 to which signal CTD-Vcom-E is applied does not deflect, displaying black. Consequently, a checkerboard pattern appears on the touch display structure 14, with portions of the liquid crystal structure corresponding to adjacent common electrodes and pixel electrodes appearing one black and one white. In this case, if a short circuit occurs in the lines electrically connected to the common electrode 1401 and the pixel electrode, this can be directly detected by detecting abnormal checkerboard patterns on the touch display structure 14.

[0238] This configuration not only provides a supplementary voltage to the common electrode 1401 during the period when the display panel 10 is in the display mode 101 to compensate for the problem that the touch signal selection circuit 120 cannot apply voltage to the common electrode 1401 at this time, but also facilitates the detection of line faults.

[0239] In some embodiments, as shown in Figures 2 and 3, the driver chip 15 is at least used to send a timing signal, and the timing control signal is used to drive the gate driving unit. The gates of the first timing switch 132 and the second timing switch 133 are used to receive the timing signal.

[0240] Specifically, the timing control signal is a commonly used timing signal in the driver chip 15. The driver chip 15 drives the gate driving unit to send a gate scanning signal by issuing a timing control signal, thereby controlling the sub-pixels electrically connected to the display data line to produce changes in the light emission conditions according to different colors in sequence, row by row or column by column, thereby realizing the refresh change of the display content of the display panel 10 and saving the number of display signal lines 112.

[0241] FIG4 shows a timing diagram in which both the signal VGH-G and the signal En-Touch are timing signals. Furthermore, the level changes of the signals VGH-G and En-Touch coincide with the display mode 101 and the touch mode 102 of the display panel 10, and can be used to control the opening or closing of the first timing switch 132 and the second timing switch 133 when the display panel 10 is in different modes.

[0242] Therefore, the timing control signal can be used to control the opening or closing of the first timing switch 132 and the second timing switch 133 when the display panel 10 is in different modes. Furthermore, the introduction of other control timings can be avoided. Thus, while the control of the first timing switch 132 and the second timing switch 133 is achieved, the introduction of new control timings can be avoided, thereby avoiding the need to occupy more pins of the driver chip 15. Furthermore, the control of the first timing switch 132 and the second timing switch 133 can be achieved without placing additional requirements on the specifications of the driver chip 15, thereby reducing costs.

[0243] The present application also provides a display device, which includes any of the above-mentioned display panels.

[0244] The present application also provides a control method for a display panel 10. As shown in FIG3 and FIG5 to FIG23 and with reference to the timing diagram shown in FIG4, the display panel 10 includes a display signal selection circuit 110, a touch signal selection circuit 120 and a timing selection circuit 130.

[0245] The timing selection circuit 130 includes a plurality of timing selection lines 131 , a plurality of first timing switches 132 , and a plurality of second timing switches 133 . Each timing selection line 131 is electrically connected to a gate of a corresponding plurality of first timing switches 132 or a plurality of second timing switches 133 .

[0246] The display signal selection circuit 110 and the touch signal selection circuit 120 are both electrically connected to the first timing switch 132 and the second timing switch 133 of the timing selection circuit 130. The timing selection circuit 130 is electrically connected to the display data line through the first timing switch 132 and to the touch signal line through the second timing switch 133.

[0247] When the display panel 10 is in display mode 101, the first timing switch 132 is turned on and the second timing switch 133 is turned off according to the timing signal transmitted by the timing selection line 131. The display signal transmitted by the display signal selection circuit 110 is transmitted to the display data line through the timing selection circuit 130.

[0248] When the display panel 10 is in touch mode 102, the first timing switch 132 is closed and the second timing switch 133 is opened according to the timing signal transmitted by the timing selection line 131. The touch signal transmitted by the touch signal selection circuit 120 is transmitted to the touch signal line through the timing selection circuit 130.

[0249] By introducing the first timing switch 132 and the second timing switch 133 and the corresponding timing selection circuit 130, and combining them with the corresponding control method, corresponding signals can be transmitted for different modes of the display panel 10 through multiple timing selection lines 131 to control the opening or closing of the first timing switch 132 and the second timing switch 133, so as to electrically connect the touch signal selection circuit 120 to the touch signal line in different modes of the display panel, or electrically connect the display signal selection circuit 110 to the display data line. Therefore, an integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120 can be realized, and the problem of signal short circuit in the line formed after integration can be avoided by the first timing switch 132 and the second timing switch 133. Furthermore, the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120, i.e., the width W shown in FIG. 2 , can be reduced without affecting the operation of the display panel 10.

[0250] In some embodiments, as shown in FIG3 and FIG5 to FIG23 and with reference to the timing diagram shown in FIG4 , the touch signal selection circuit 120 includes a touch selector line 121, a plurality of touch detection lines 123, and a plurality of detection switches 124. The display signal selection circuit 110 includes a pixel selector line 111, a plurality of display signal lines 112, and a plurality of display switches 113.

[0251] The touch selector line 121 includes multiple sub-touch selection lines 1210. Each sub-touch selection line 1210 is electrically connected to the gates of multiple detection switches 124 and is used to control the opening or closing of the detection switches 124. The touch detection lines 123 are electrically connected to the timing selection circuit 130 through the corresponding detection switches 124. When the detection switches 124 are turned on, the touch detection lines 123 are electrically connected to the timing selection circuit 130 through the corresponding detection switches 124.

[0252] The pixel selector line 111 includes a plurality of sub-pixel selection lines 1110. Each sub-pixel selection line 1110 is electrically connected to the gates of a plurality of display switches 113 and is used to control the on / off state of the display switches 113. When a display switch 113 is on, the display signal line 112 is electrically connected to the timing selection circuit 130 via the corresponding display switch 113.

[0253] Through the above configuration, combined with the control method, an integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120 can be specifically implemented. Furthermore, the timing selection circuit 130 can be used to avoid signal short circuits in the integrated lines. Consequently, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced, i.e., the width W shown in FIG. 2 , without affecting the operation of the display panel 10.

[0254] In some embodiments, as shown in Figures 3 and 5 to 23 and with reference to the timing diagram shown in Figure 4, the touch selector line 121 includes multiple sub-touch select lines 1210. Each sub-touch select line 1210 is electrically connected to a plurality of fourth timing switches 128 and, through the plurality of fourth timing switches 128, is electrically connected to the gates of a corresponding plurality of detection switches 124. Each sub-touch select line 1210 is configured to control the on / off state of the detection switches 124 when the fourth timing switches 128 are on. The touch detection line 123 is electrically connected to a plurality of sixth timing switches 129 and, through the plurality of sixth timing switches 129, is electrically connected to the sources of the corresponding plurality of detection switches 124. The gates of the sixth timing switches 129, the fourth timing switches 128, and the second timing switch 133 receive the same timing signal.

[0255] The pixel selector line 111 includes a plurality of sub-pixel selection lines 1110. Each sub-pixel selection line 1110 is electrically connected to a plurality of third timing switches 114 and, through the plurality of third timing switches 114, is electrically connected to the gates of the corresponding plurality of display switches 113. Each sub-pixel selection line 1110 is configured to control the on / off switching of the display switches 113 when the third timing switches 114 are on. The display signal line 112 is electrically connected to a plurality of fifth timing switches 115 and, through the plurality of fifth timing switches 115, is electrically connected to the sources of the corresponding plurality of display switches 113. The gates of the fifth timing switches 115, the third timing switches 114, and the first timing switch 132 receive the same timing signal.

[0256] The detection switch 124 and the display switch 113 are multiplexed switches, and the corresponding sub-pixel selection line 1110 and the sub-touch selection line 1210 are electrically connected to the gate of the multiplexed switch. The sub-pixel selection line 1110 controls the opening or closing of the switch when the third timing switch 114 and the fifth timing switch 115 are turned on, and the sub-touch selection line 1210 controls the opening or closing of the switch when the fourth timing switch 128 and the sixth timing switch 129 are turned on.

[0257] By providing the first timing switch 132 and the display signal selection circuit 110, and the second timing switch 133 and the touch signal selection circuit 120, and combining them with corresponding control methods, the detection switch 124 and the display switch 113 can be integrated into a multiplexed switch. This further enables an integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120. Furthermore, the timing selection circuit 130 can be used to avoid signal short circuits in the lines formed after integration. Furthermore, the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120, i.e., the width W shown in FIG. 2 , can be reduced without affecting the operation of the display panel 10.

[0258] In some embodiments, as shown in FIG. 3 and FIG. 5 to FIG. 23 and referring to the timing diagram shown in FIG. 4 , the touch signal selection circuit 120 further includes a compensation selector line 122 , a compensation switch 126 , and a compensation signal line 125 .

[0259] The compensation selector line 122 includes a plurality of compensation selection lines 1220. Each compensation selection line 1220 is electrically connected to the gates of a plurality of compensation switches 126 and is used to control the opening or closing of the compensation switches 126. The compensation signal line 125 is electrically connected to the timing selection circuit 130 through the plurality of compensation switches 126.

[0260] The timing selection circuit 130 includes a plurality of sub-selection groups 136, each of which is electrically connected to a different display data line and touch data line. The drain of each compensation switch 126 and the drain of the corresponding detection switch 124 are electrically connected to the same sub-selection group 136. The compensation switches 126 and detection switches 124 electrically connected to the same sub-selection group 136 are alternately turned on during the period when the display panel 10 is in the touch mode 102.

[0261] Through the above-mentioned arrangement and in combination with the corresponding control method, the touch detection accuracy of the display panel 10 can be improved while achieving the touch function by electrically connecting the touch signal selection circuit 120 to the touch signal line in different modes of the display panel, or the display signal selection circuit 110 can be electrically connected to the display data line to achieve the display function. Thus, the integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120 can be specifically implemented in another way, and the problem of signal short circuit in the line formed after integration can be avoided by using the first timing switch 132 and the second timing switch 133. Furthermore, in another way, the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120 can be reduced without affecting the operation of the display panel 10, that is, the width W shown in Figure 2.

[0262] In some embodiments, as shown in FIG. 3 and FIG. 5 to FIG. 23 and referring to the timing diagram shown in FIG. 4 , the touch signal selection circuit 120 further includes a compensation selector line 122 , a compensation switch 126 , and a compensation signal line 125 .

[0263] The compensation selector lines 122 include a plurality of compensation selection lines 1220. Each compensation selection line 1220 is electrically connected to a plurality of fourth sequential switches 128 and, through the fourth sequential switches 128, to the gate of the compensation switch 126.

The compensation signal line 125 is electrically connected to a plurality of sixth sequential switches 129 and, through the sixth sequential switches 129, to the source of the compensation switch 126. Furthermore, the compensation signal line 125 is electrically connected to the timing selection circuit 130 through the compensation switch 126. The gates of the sixth sequential switches 129, the fourth sequential switches 128, and the second sequential switch 133 receive the same timing signal.

[0264] The pixel selector line 111 includes a plurality of sub-pixel selection lines 1110. Each sub-pixel selection line 1110 is electrically connected to a plurality of third timing switches 114 and, through the plurality of third timing switches 114, is electrically connected to the gates of the corresponding plurality of display switches 113. Each sub-pixel selection line 1110 is configured to control the on / off switching of the display switches 113 when the third timing switches 114 are on. The display signal line 112 is electrically connected to a plurality of fifth timing switches 115 and, through the plurality of fifth timing switches 115, is electrically connected to the sources of the corresponding plurality of display switches 113. The gates of the fifth timing switches 115, the third timing switches 114, and the first timing switch 132 receive the same timing signal.

[0265] Compensation switch 126 and display switch 113 are multiplexing switches, and the corresponding subpixel select line 1110 and compensation select line 1220 are electrically connected to the gate of the multiplexing switch. Subpixel select line 1110 controls the opening or closing of the multiplexing switch when the third timing switch 114 and the fifth timing switch 115 are turned on, and compensation select line 1220 controls the opening or closing of the multiplexing switch when the fourth timing switch 128 and the sixth timing switch 129 are turned on.

[0266] The timing selection circuit 130 includes a plurality of sub-selection groups 136, each of which is electrically connected to a different display data line and touch data line. The drain of each compensation switch 126 and the drain of the corresponding detection switch 124 are electrically connected to the same sub-selection group 136. The compensation switches 126 and detection switches 124 connected to the same sub-selection group 136 are alternately turned on when the display panel 10 is in the touch mode 102.

[0267] Through the above-mentioned arrangement and in combination with the corresponding control method, it is possible to specifically realize that the touch signal selection circuit 120 is electrically connected to the touch signal line to realize the touch function in different modes of the display panel, or the display signal selection circuit 110 is electrically connected to the display data line to realize the display function. Thus, it is possible to specifically realize the integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120, and avoid the problem of signal short circuit in the line formed after the integration by the first timing switch 132 and the second timing switch 133. Furthermore, it is possible to reduce the border width of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120, that is, the width W shown in Figure 2, without affecting the operation of the display panel 10.

[0268] In some embodiments, as shown in FIG3 and FIG5 to FIG23 and with reference to the timing diagram shown in FIG4, the display panel 10 further includes: a plurality of touch driving units 310. The plurality of touch driving units 310 are electrically connected to the same compensation selector line 122, the same touch selector line 121, and the same compensation signal line 125.

[0269] Each touch drive unit 310 includes at least two sub-touch drive groups 311, each of which is electrically connected to at least two adjacent touch signal lines. Each of the at least two sub-touch drive groups 311 includes two second timing switches 133, a detection switch 124, and a display switch 113. Since the display switch 113 and the compensation switch 126 are multiplexed switches, the display switch 113 can also be described as the compensation switch 126. The at least two sub-touch drive groups 311 within the same touch drive unit 310 share the same touch detection line 123, which is electrically connected to the two detection switches 124.

[0270] The at least two touch driving sub-groups 311 of each touch driving unit 310 are electrically connected to the at least two touch selection sub-lines 1210 , and are electrically connected to the at least two compensation selection lines 1220 .

[0271] When the display panel 10 is in the touch mode 102, in the first time period 1021, one touch sub-drive group is electrically connected to the touch detection line 123, and the other touch sub-drive group is electrically connected to the compensation signal line 125. In the second time period 1022, the electrical connection targets of the two touch sub-drive groups are swapped.

[0272] Through the above-described configuration and in combination with a corresponding control method, an integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120 can be specifically implemented. Furthermore, the first timing switch 132 and the second timing switch 133 can be used to prevent signal short circuits in the integrated lines. Consequently, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120, i.e., the width W shown in FIG. 2 , can be reduced without affecting the operation of the display panel 10.

[0273] In some embodiments, as shown in FIG3 and FIG5 to FIG23 and with reference to the timing diagram shown in FIG4, the display panel 10 further includes a plurality of display driving units 210. The plurality of display driving units 210 are electrically connected to the same pixel selector line 111. Each pixel driving unit 210 is electrically connected to one display signal line 112.

[0274] Each display driver unit 210 includes at least two sub-display driver groups 211. Each of the at least two sub-display driver groups 211 includes at least two first timing switches 132 and one display switch 113. Since the display switch 113 and the compensation switch 126 are multiplexed switches, the display switch 113 herein can also be described as the compensation switch 126. The pixel selector lines 111 include at least two sub-pixel selection lines 1110. The at least two sub-display driver groups 211 of each display driver unit 210 are electrically connected to the at least two sub-pixel selection lines 1110, respectively.

[0275] When the display panel 10 is in display mode 101, at least two sub-pixel select lines 1110 are electrically connected to at least two display switches 113 through at least two first timing switches 132 located within the same display driver unit 210. The display signal line 112 is divided into at least two display signal branches 1121. The at least two display signal branches 1121 are electrically connected to at least two display switches 113 through at least two other first timing switches 132 located within the same display driver unit 210. After passing through the display switches 113, they are electrically connected to at least two display data lines.

[0276] Through the above-described configuration and in combination with a corresponding control method, an integrated design of the display signal selection circuit 110 and the touch signal selection circuit 120 can be specifically implemented. Furthermore, the first timing switch 132 and the second timing switch 133 can be used to prevent signal short circuits in the integrated lines. Consequently, the width of the border of the display panel 10 occupied by the display signal selection circuit 110 and the touch signal selection circuit 120, i.e., the width W shown in FIG. 2 , can be reduced without affecting the operation of the display panel 10.
