Description

Technical Field

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

[0002] In order to implement a touch function in existing display devices, the incell (setting the touch layer in the display panel) technology is adopted to integrate the display drive and the touch drive together on the display panel. And in order to reduce costs and the thickness of the display device, the common electrode blocks in the common electrode layer are reused as touch electrodes. As display devices develop towards large sizes, narrow borders, and high screen ratios, in order to keep the touch accuracy unchanged, more touch traces need to be added, and each touch trace requires a channel on the corresponding driver chip to output signals. However, the number of channels of a driver chip is limited, so more driver chips need to be added accordingly, resulting in higher costs and larger borders of the display device. To solve the above problems, in existing display devices, one touch signal line is used to control two touch electrodes in the plane, so as to reduce the touch traces without sacrificing the touch accuracy. However, during the operation of the display device, it is found that when no signal is input to the touch electrode, the touch electrode is in a passive state, and the touch electrode is prone to accidental touch by other signals, and the touch electrode will also affect other signals, resulting in poor display. To solve this problem, existing display devices will set a signal line to input a signal to the touch electrode in a passive state to improve the stability of the touch electrode. From the above description, it can be seen that in order to make the touch electrode work properly, in addition to setting the touch signal line, a signal line also needs to be set, and the touch electrode is driven through the corresponding circuit, resulting in a larger lower border of the display panel, and the signals output to the touch electrode will be different between the proximal end and the distal end, resulting in problems of poor touch and display.

[0003] Therefore, there is a technical problem in existing display devices that the signals output to the touch electrode are different between the proximal end and the distal end, resulting in poor touch and display. Summary of the Invention

[0004] Embodiments of the present application provide a display panel and a display device to solve the technical problem that in existing display devices, the signals output to the touch electrode are different between the proximal end and the distal end, resulting in poor touch and display.

[0005] To achieve the above object, according to the first aspect of the present application, a display panel is provided. The display panel includes a display area and a non-display area.

The common circuit can improve the voltage stability of the passive touch control electrode. Moreover, the touch control circuit is disposed in the first sub-region, and the common circuit is disposed in the second sub-region, which can reduce the width of the lower border, make the touch control circuit and the common circuit closer to the display area, reduce the attenuation in the signal transmission process, and the common signal is input from both ends, reducing the signal difference between the proximal end and the distal end, and improving the touch control and display effects.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0030] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "electrical connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] To illustrate the principle of the technical problem in the embodiments of the present application, a comparative display device is provided. It can be understood that the comparative display device cannot be regarded as the prior art of the embodiments of the present application. As Figure 1 shown, the comparative display device 1 includes a display area 101 and a non-display area 102. A plurality of electrode blocks are provided in the display area 101. The plurality of electrode blocks include a first electrode block 101a and a second electrode block 101b. In the touch stage, the electrode blocks receive touch signals, and in the display stage, the electrode blocks receive common signals, thereby realizing the in-cell design and multiplexing the electrode blocks as common electrode blocks and touch electrode blocks.

[0032] At the same time, in order to reduce the touch chip and reduce the border of the comparative display device 1, a touch line 13 is connected to two electrode blocks. As Figure 1 shown, it can be seen that a touch line 13 is connected to the first electrode block 101a and the second electrode block 101b. And in order to avoid interference between the two electrode blocks, a control circuit needs to be set to control the signals output to the first electrode block 101a and the second electrode block 101b. As Figure 1 shown, a touch signal control circuit 102b is provided to control the signals input to the touch line.

[0033] However, in the actual use process, it is found that when a signal is input to one electrode block, the other electrode block will be in a passive state, and this electrode block will be coupled with other electrode blocks and / or signal lines, resulting in false touch, or this electrode block affects the signals of other signal lines, resulting in poor display. To solve this problem, as Figure 1 shown, the comparative display device 1 will set a common signal control circuit 102a to input signals to the touch electrodes in the passive state through the common signal control circuit 102a, so as to improve the voltage stability of the touch electrodes. But from Figure 1As can be seen, since multiple circuits need to be set, the signal attenuates severely when transmitted from the signal line or the touch line to the touch electrode, and it will cause a large difference in the signals received by the touch electrodes near the lower border and the touch electrodes far from the lower border, thereby affecting the touch effect and the display effect. Therefore, there is a technical problem in the existing display device that the signals output to the touch electrodes are different at the proximal end and the distal end, resulting in poor touch and display.

[0034] In view of the above technical problems, an embodiment of the present application provides a display panel and a display device to solve the above technical problems.

[0036] As Figures 2 to 5 shown, an embodiment of the present application provides a display panel. The display panel 2 includes a display area 201 and a non-display area 202. The non-display area 202 includes a first sub-area 202a and a second sub-area 202b provided at both ends of the display area 201. The display panel 2 includes a touch electrode 21, a touch signal line 22, a touch circuit 23, and a common circuit 24. The touch electrode 21 is provided in the display area 201. The touch signal line 22 is electrically connected to the touch electrode 21. The touch circuit 23 is connected to the touch signal line 22 and the touch electrode 21. The common circuit 24 is connected to the touch electrode 21;

[0037] Among them, the touch circuit 23 is disposed in the first sub-region 202a, and the common circuit 24 is disposed in the second sub-region 202b.

[0038] An embodiment of the present application provides a display panel. By providing the touch circuit 23 and the common circuit 24, the touch circuit 23 can implement the touch function of the display panel 2, and the common circuit 24 can improve the voltage stability of the passive touch electrode 21. Moreover, the touch circuit 23 is disposed in the first sub-region 202a, and the common circuit 24 is disposed in the second sub-region 202b, which can reduce the width of the lower border, make the touch circuit 23 and the common circuit 24 closer to the display area, reduce the attenuation in the signal transmission process, and the common signal is input from both ends, reducing the signal difference between the proximal end and the distal end, and improving the touch and display effects.

[0039] Specifically, it can be understood that in the embodiment of the present application, the touch electrode 21 is multiplexed as the common electrode, that is, a plurality of electrodes arranged at intervals can be formed by using the common electrode layer in the display panel 2, and the electrode is multiplexed as the touch electrode 21 and the common electrode. In the touch stage, the touch electrode 21 transmits a touch signal to implement the touch function (the specific signal transmission process can be referred to the following embodiments), and in the display stage, the touch electrode 21 transmits a common signal to implement the display function.

[0040] Specifically, the effective level refers to the electrical signal that can turn on the transistor, and the invalid level refers to the electrical signal that turns off the transistor. When a high-potential signal is input to the gate of the transistor, the transistor turns on, then the effective level refers to the high-potential signal. When a low-potential signal is input to the gate of the transistor, the transistor turns on, then the effective level refers to the low-potential signal. The embodiment of the present application takes the case where the transistor turns on when a high-potential signal is input to the gate of the transistor as an example for illustration. It can be understood that the type of the transistor can be changed so that the transistor turns on when a low-potential signal is input to the gate of the transistor.

[0041] Specifically, the touch method of the display panel in the embodiment of the present application can be self-capacitance touch.

[0042] Specifically, in the embodiment of the present application, in order to reduce the number of touch signal lines, one touch signal line is connected to a plurality of touch electrodes (for example, two touch electrodes). At the same time, in order to avoid interference between the touch electrodes connected to the same touch signal line, a touch circuit is provided. Therefore, it can be understood that the touch circuit is a control circuit provided to enable the two touch electrodes connected to the same touch signal line to work independently. By providing the touch circuit, each touch electrode can input a touch signal separately. And the touch circuit can control the common signal to be output to the common electrode when the touch electrode is used as the common electrode.

[0043] Specifically, in the embodiments of the present application, when setting the signals output by the touch control circuit to two touch electrodes connected to the same touch signal line, it can be understood that when one of the two touch electrodes connected to the same touch signal line inputs a touch signal, the other will be in a passive state. To prevent the touch electrode in the passive state from interfering with other touch electrodes or other signal lines, the embodiments of the present application will set a common circuit, so that the common circuit can control the output of a regulated signal to the passive touch electrode, thereby improving touch stability, and the common circuit can control the common signal line to output a common signal to the common electrode when the touch electrode serves as the common electrode.

[0044] Specifically, as Figure 2 shown, the non-display area 202 includes a first sub-area 202a and a second sub-area 202b arranged at both ends of the display area 201 along the first direction Y. The non-display area 202 further includes a left border area (not shown) and a right border area (not shown) arranged on both sides of the display area 201 along the second direction X. A gate driving circuit can be arranged in the left border area and / or the right border area. The included angle between the first direction Y and the second direction X is greater than 0 and less than or equal to 90 degrees. However, the embodiments of the present application are not limited to this. The non-display area 202 can only include the first sub-area and the second sub-area. And the first sub-area and the second sub-area can be bent to the back side of the display panel.

[0045] Specifically, as Figure 2 shown, the touch control circuit 23 can be arranged in the first sub-area 202a, and the common circuit 24 can be arranged in the second sub-area 202b. Figure 2 Taking the example that the first sub-area is below the display area and the second sub-area is above the display area, the embodiments of the present application are not limited to this. The first sub-area can be above the display area, and the second sub-area can be arranged below the display area.

[0046] Specifically, as Figure 1 、 Figure 2 shown, compared with the contrast display device in which both the common signal control circuit 102a and the touch signal control circuit 102b are arranged in the lower border, which will result in a longer transmission distance when the touch signal is output, and the common signal and the touch signal are severely attenuated when transmitted to the touch electrodes near the upper border, resulting in poor touch and display. In the embodiments of the present application, by arranging the touch control circuit in the first sub-area and the common circuit in the second sub-area, first, the length of the signal trace between the touch control circuit and the touch electrode is shortened, the voltage drop is reduced, and the signal difference between the proximal end and the distal end is reduced. Then, the regulated signal / common signal will be input from the first sub-area and the second sub-area simultaneously, reducing the signal difference between the proximal end and the distal end, and improving the touch stability and the display effect.

[0047] In some embodiments, as Figure 2As shown, the display panel 2 further includes a driving chip 26, the driving chip 26 is disposed in the first sub-region 202a, and the touch control circuit 23 is located between the driving chip 26 and the touch control electrodes 21.

[0048] In some embodiments, the first sub-region 202a is a lower border region, the second sub-region 202b is an upper border region, the touch control circuit 23 is disposed in the lower border region, and the common circuit 24 is disposed in the upper border region. By disposing the touch control circuit in the lower border region and the common circuit in the upper border region, it is possible to avoid winding of the touch control signal lines, reduce the voltage drop on the touch control signal lines, and avoid excessive space occupation by the winding of the touch control signal lines.

[0049] Specifically, it can be understood that the lower border region includes a bonding region. The lower border region is the region where the display panel is bonded to the driving chip. Bonding terminals are provided in the lower border region, and the signals input by the driving chip are input from the lower border region. Therefore, if the touch control circuit is disposed in the upper border region, all the touch control signal lines need to be wound from the two side borders to the upper border region, resulting in a large impedance of each touch control signal line, a large voltage drop in the transmission of the touch control signal lines, and a large number of touch control signal lines, occupying a large amount of space. In the embodiment of the present application, the touch control circuit is disposed in the lower border region, so that the touch control signal lines can be directly connected to the touch control circuit without winding, reducing the voltage drop of the touch control signal lines and the space occupied by the touch control signal lines. And there is only one voltage stabilizing signal line, and the space occupied by the winding of one voltage stabilizing signal line is small, and its line width can also be increased, so that the voltage drop is small.

[0050] In some embodiments, as Figures 2 to 4 shown, the touch control circuit 23 includes a control transistor 231 and a control signal line 232. The gate of the control transistor 231 is connected to the control signal line 232, the first electrode of the control transistor 231 is connected to the touch control signal line 22, and the second electrode of the control transistor 231 is connected to the touch control electrode 21. By connecting the gate of the control transistor to the control signal line, the first electrode of the control transistor to the touch control signal line, and the second electrode of the control transistor to the touch control electrode, it is possible to control whether the touch control signal line sends a signal to the touch control electrode by turning on and off the control transistor. Thus, when multiple touch control electrodes are connected to the same touch control signal line, by controlling the conduction or cutoff of the control transistor circuit, time-division driving of multiple touch control electrodes electrically connected to the same touch control signal line is achieved, and each touch control electrode can work independently, thereby improving touch accuracy.

[0051] In some embodiments, as Figure 3 、 Figure 4As shown, the display panel 2 includes a plurality of touch electrodes 21 arranged in an array and a plurality of touch signal lines 22, and the touch circuit 23 includes a plurality of control transistors 231 and two control signal lines 232;

[0052] Among them, the gates of the plurality of control transistors 231 connecting the plurality of touch electrodes 21 in the same row are connected to the same control signal line 232, the gates of the plurality of control transistors 231 connecting the plurality of touch electrodes 21 in adjacent rows are connected to different control signal lines 232, the gates of the plurality of control transistors 231 connecting the two rows of touch electrodes 21 arranged at intervals are connected to the same control signal line 232, and the first electrodes of the plurality of control transistors 231 connecting the plurality of touch electrodes 21 in the same row are connected to different touch signal lines 22. By making the gates of the plurality of control transistors 231 connecting the plurality of touch electrodes in the same row connected to the same control signal line 232, the gates of the plurality of control transistors 231 connecting the plurality of touch electrodes in adjacent rows connected to different control signal lines 232, and the gates of the plurality of control transistors 231 connecting the two rows of touch electrodes 21 arranged at intervals connected to the same control signal line 232, the number of control signal lines can be reduced, thereby reducing the border, and the first electrodes of the plurality of control transistors in the same row are connected to different touch signal lines to prevent poor touch caused by the touch electrodes connected to the same touch signal line being turned on simultaneously.

[0053] In some embodiments, as Figure 6 、 Figure 7 shown, the two control signal lines 232 include a first control signal line TP-Mux-SC1 and a second control signal line TP-Mux-SC2, the plurality of control transistors 231 include a first control transistor T11 and a second control transistor T21, the touch signal line 22 includes a first touch signal line TX1, the first control signal line TP-Mux-SC1 is connected to the gate of the first control transistor T11, the second control signal line TP-Mux-SC2 is connected to the gate of the second control transistor T21, the control transistor 231 is disposed between the touch electrode 21 and the first control signal line TP-Mux-SC1, the first control signal line TP-Mux-SC1 is disposed between the control transistor 231 and the second control signal line TP-Mux-SC2, and the second control signal line TP-Mux-SC2 is disposed between the first control signal line TP-Mux-SC1 and the touch signal line 22;

[0054] Among them, the display panel 2 includes a substrate 311, a first metal layer 314, and a second metal layer 316 arranged in sequence. The first control signal line TP-Mux-SC1 and the second control signal line TP-Mux-SC2 include two parts. The first part SC1-1 of the first control signal line TP-Mux-SC1 is disposed on the first metal layer 314, and the second part SC1-2 of the first control signal line TP-Mux-SC1 is disposed on the second metal layer 316. The first part SC1-1 of the first control signal line TP-Mux-SC1 is connected to the second part SC1-2 of the first control signal line TP-Mux-SC1 and the gate of the first control transistor T11;

[0055] The first part SC2-1 of the second control signal line TP-Mux-SC2 is disposed on the first metal layer 314, and the second part SC2-2 of the second control signal line TP-Mux-SC2 is disposed on the second metal layer 316. The first part SC2-1 of the second control signal line TP-Mux-SC2 is connected to the second part SC2-2 of the second control signal line TP-Mux-SC2 and the gate of the second control transistor T21;

[0056] The first part TX1-1 of the first touch signal line TX1 is disposed on the first metal layer 314, and the second part TX1-2 of the first touch signal line TX1 is disposed on the second metal layer 316. The first part TX1-1 of the first touch signal line TX1 is connected to the second part TX1-2 of the first touch signal line TX1 and the control transistor 231.

[0057] Specifically, the above embodiment is described by taking the design of the first touch signal line as an example. For the design of other touch signal lines, reference can be made to the design of the first touch signal line.

[0058] Specifically, as Figure 6 shown, the display panel 2 includes a substrate 311, an active layer 312, a gate insulating layer 313, a first metal layer 314, an interlayer insulating layer 315, a second metal layer 316, a planarization layer 317, a first electrode layer 318, a passivation layer 319, and a second electrode layer 321 arranged in sequence.

[0059] Specifically, the impedance of the second metal layer is less than that of the first metal layer.

[0060] Specifically, the first metal layer includes the gates of the transistors, and the second metal layer includes the first electrodes and the second electrodes of the transistors.

[0061] Specifically, in the embodiments of the present application, when not specifically stated, the connection lines are disposed on the second metal layer, and the touch electrodes are disposed on the first electrode layer or the second electrode layer.

[0062] Specifically, Figure 6 Taking the film layer design of a display panel as an example for illustration, but the embodiments of the present application are not limited thereto. For example, the display panel may include three or more metal layers, may include two active layers of different materials (one layer may be low-temperature polysilicon and one layer may be metal oxide), the positions of the second electrode layer and the first electrode layer may be swapped, the positions of the first metal layer and the second metal layer may be swapped, etc. The embodiments of the present application will not elaborate on this anymore.

[0063] Specifically, when setting the control signal lines, control transistors, and touch signal lines, in order to reduce the impedance of the signal lines, the control signal lines and the touch signal lines are disposed on the second metal layer. However, the control signal lines need to be connected to the gates of the control transistors, and the touch signal lines need to be connected to the first electrodes of the control transistors. Moreover, there may be intersections between the control signal lines, and there may be intersections between the control signal lines and the touch signal lines. Therefore, the control signal lines can include two parts, with one part connected to the gates of the transistors and the other part disposed on the second metal layer, and the touch signal lines can include two parts, with one part connected to the second electrodes of the transistors and the other part disposed on the second metal layer to avoid short circuits and reduce the impedance of each signal line.

[0064] In some embodiments, as Figure 6 、 Figure 8 shown, the two control signal lines 232 include a first control signal line TP-Mux-SC1 and a second control signal line TP-Mux-SC2, and the multiple control transistors 231 include a first control transistor T11 and a second control transistor T21. The first control signal line TP-Mux-SC1 is connected to the gate of the first control transistor T11, the second control signal line TP-Mux-SC2 is connected to the gate of the second control transistor T21. The first control signal line TP-Mux-SC1 is disposed between the touch electrode 21 and the second control signal line TP-Mux-SC2, the second control signal line TP-Mux-SC2 is disposed between the first control signal line TP-Mux-SC1 and the control transistors 231, and the control transistors 231 are disposed between the second control signal line TP-Mux-SC2 and the touch signal line 22;

[0065] Among them, the display panel 2 includes a substrate 311, a first metal layer 314, and a second metal layer 316 arranged in sequence. The first control signal line TP-Mux-SC1 and the second control signal line TP-Mux-SC2 include two parts. The first part SC1-1 of the first control signal line TP-Mux-SC1 is disposed on the first metal layer 314, and the second part SC1-2 of the first control signal line TP-Mux-SC1 is disposed on the second metal layer 316. The first part SC1-1 of the first control signal line TP-Mux-SC1 is connected to the second part SC1-2 of the first control signal line TP-Mux-SC1 and the gate of the first control transistor T11;

[0066] The first part SC2-1 of the second control signal line TP-Mux-SC2 is disposed on the first metal layer 314, and the second part SC2-2 of the second control signal line TP-Mux-SC2 is disposed on the second metal layer 316. The first part SC2-1 of the second control signal line TP-Mux-SC2 is connected to the second part SC2-2 of the second control signal line TP-Mux-SC2 and the gate of the second control transistor T21. Specifically, the touch signal line can be disposed on the second metal layer.

[0067] Specifically, as Figure 3 shown, taking a touch signal line 22 connecting at least two adjacent touch electrodes 21 as an example, it can be seen that the touch signal line 22 includes a first touch signal line TX1, the touch electrodes 21 include a first touch electrode Sensor11 and a second touch electrode Sensor12, the plurality of control transistors 231 include a first control transistor T11 and a second control transistor T21, and the plurality of control signal lines 232 include a first control signal line TP-Mux-SC1 and a second control signal line TP-Mux-SC2. From Figure 3As can be seen, the first touch electrode Sensor11 and the second touch electrode Sensor12 are both electrically connected to the first touch signal line TX1. In order to enable the first touch electrode Sensor11 and the second touch electrode Sensor12 to work independently, a first control transistor T11 and a second control transistor T21 are respectively arranged between the first touch electrode Sensor11 and the second touch electrode Sensor12 and the first touch signal line TX1.

Thus, through the control of the first control signal line TP-Mux-SC1 and the second control signal line TP-Mux-SC2, the first touch electrode Sensor11 and the second touch electrode Sensor12 can work independently.

[0068] Specifically, as Figure 4 shown, taking a touch signal line 22 connecting two adjacent touch electrodes 21 as an example, it can be seen that the touch signal line 22 includes a first touch signal line TX1, a second touch signal line TX2, a third touch signal line TX3, and a fourth touch signal line TX4.

To enable each touch electrode to work independently, two touch electrodes electrically connected to the same touch signal line need to control the input or non-input of signals through transistors. For example, Figure 4 as shown, a first control transistor T11 and a second control transistor T21 are respectively provided between the first touch electrode Sensor11 and the second touch electrode Sensor12 and the first touch signal line TX1, a third control transistor T12 and a fourth control transistor T22 are respectively provided between the third touch electrode Sensor13 and the fourth touch electrode Sensor14 and the second touch signal line TX2, a fifth control transistor T13 and a sixth control transistor T23 are respectively provided between the fifth touch electrode Sensor21 and the sixth touch electrode Sensor22 and the third touch signal line TX3, and a seventh control transistor T14 and an eighth control transistor T24 are respectively provided between the seventh touch electrode Sensor23 and the eighth touch electrode Sensor24 and the fourth touch signal line TX4.

[0070] Specifically, as Figure 4 shown, the first touch electrode Sensor11, the second touch electrode Sensor12, the third touch electrode Sensor13, and the fourth touch electrode Sensor14 are arranged in the same column, the fifth touch electrode Sensor21, the sixth touch electrode Sensor22, the seventh touch electrode Sensor23, and the eighth touch electrode Sensor24 are arranged in the same column, the first touch electrode Sensor11, the second touch electrode Sensor12, the third touch electrode Sensor13, and the fourth touch electrode Sensor14 are respectively arranged in the same row as the fifth touch electrode Sensor21, the sixth touch electrode Sensor22, the seventh touch electrode Sensor23, and the eighth touch electrode Sensor24, the first touch electrode Sensor11 and the third touch electrode Sensor13 are spaced apart in two rows, and the second touch electrode Sensor12 and the fourth touch electrode Sensor14 are spaced apart in two rows.

[0073] In some embodiments, such as Figure 3 、 Figure 4As shown, the common circuit 24 includes a voltage stabilizing transistor 241, a voltage stabilizing control line 242, and a voltage stabilizing signal line LFD. The gate of the voltage stabilizing transistor 241 is connected to the voltage stabilizing control line 242. The first electrode of the voltage stabilizing transistor 241 is connected to the voltage stabilizing signal line LFD. The second electrode of the voltage stabilizing transistor 241 is connected to the touch electrode 21. By setting the voltage stabilizing signal line, when there are passive touch electrodes among multiple touch electrodes electrically connected to the same touch signal line, a voltage stabilizing signal can be input to the touch electrode through the voltage stabilizing signal line. In order to avoid interference between the voltage stabilizing signal and the touch signal, a voltage stabilizing transistor can be set to control the input of the voltage stabilizing signal, inputting a touch signal when the touch electrode realizes the touch function and inputting a voltage stabilizing signal when the touch electrode does not perform touch, thereby improving the stability of the touch electrode.

The first electrodes of the plurality of voltage stabilizing transistors 241 connecting the plurality of touch electrodes 21 in the same column are connected to the same voltage stabilizing signal line LFD. By connecting the gates of the plurality of voltage stabilizing transistors 241 connecting the plurality of touch electrodes in the same row to the same voltage stabilizing control line 242, connecting the gates of the plurality of voltage stabilizing transistors 241 connecting the plurality of touch electrodes in adjacent rows to different voltage stabilizing control lines 242, and connecting the gates of the plurality of voltage stabilizing transistors 241 connecting the two touch electrodes 21 arranged at intervals to the same voltage stabilizing control line 242, the number of voltage stabilizing control lines can be reduced, thereby reducing the border. Moreover, by connecting the first electrodes of the plurality of voltage stabilizing transistors in the same row to the same voltage stabilizing signal line and connecting the first electrodes of the plurality of voltage stabilizing transistors in the same column to the same voltage stabilizing signal line, the number of voltage stabilizing signal lines can be reduced and the border can be reduced.

From Figure 3 it can be seen that both the first touch electrode Sensor11 and the second touch electrode Sensor12 are electrically connected to the first touch signal line TX1. In order to ensure that when one of the first touch electrode Sensor11 and the second touch electrode Sensor12 is working, the other will not be in a passive state, and to prevent signal crosstalk between the voltage stabilizing signal line and the touch signal line transmitted to the touch electrode, a first voltage stabilizing transistor T31 and a second voltage stabilizing transistor T41 are respectively arranged between the first touch electrode Sensor11 and the second touch electrode Sensor12 and the voltage stabilizing signal line LFD. The gate of the first voltage stabilizing transistor T31 is connected to the first voltage stabilizing control line TP-Mux-MSC1, the first electrode of the first voltage stabilizing transistor T31 is connected to the voltage stabilizing signal line LFD, the second electrode of the first voltage stabilizing transistor T31 is connected to the first touch electrode Sensor11. The gate of the second voltage stabilizing transistor T41 is connected to the second voltage stabilizing control line TP-Mux-MSC2, the first electrode of the second voltage stabilizing transistor T41 is connected to the voltage stabilizing signal line LFD, and the second electrode of the second control transistor T21 is connected to the second touch electrode Sensor12. Thus, through the control of the first voltage stabilizing control line TP-Mux-MSC1 and the second voltage stabilizing control line TP-Mux-MSC2, the input of the voltage stabilizing signals of the first touch electrode Sensor11 and the second touch electrode Sensor12 is realized.

[0079] Specifically, when setting the regulated voltage control line, the control transistor, and the regulated voltage signal line, in order to reduce the impedance of the signal line, the regulated voltage control line and the regulated voltage signal line are set on the second metal layer. However, the regulated voltage control line needs to be connected to the gate of the regulated voltage transistor, and the regulated voltage signal line needs to be connected to the first electrode of the regulated voltage transistor. Moreover, there may be intersections between the regulated voltage control lines, and there may also be intersections between the regulated voltage control line and the regulated voltage signal line. Therefore, the regulated voltage control line can include two parts. By connecting one part to the gate of the transistor and setting the other part on the second metal layer, the regulated voltage signal line can include three parts. One part is connected to the first electrode of the transistor, one part is set on the first metal layer for transfer to avoid short circuits, and one part is set on the second metal layer to reduce impedance.

[0093] Specifically, the voltage stabilizing signal line is disposed on the second metal layer.

[0094] Specifically, as Figure 4 shown, taking a touch signal line 22 connecting two adjacent touch electrodes 21 as an example, it can be seen that the touch electrodes 21 include a first touch electrode Sensor11, a second touch electrode Sensor12, a third touch electrode Sensor13, a fourth touch electrode Sensor14, a fifth touch electrode Sensor21, a sixth touch electrode Sensor22, a seventh touch electrode Sensor23, and an eighth touch electrode Sensor24.

The two voltage stabilizing control lines 242 include a first voltage stabilizing control line TP-Mux-MSC1 and a second voltage stabilizing control line TP-Mux-MSC2.

[0095] From Figure 4 it can be seen that the first touch electrode Sensor11 and the second touch electrode Sensor12 are both electrically connected to the first touch signal line TX1. The third touch electrode Sensor13 and the fourth touch electrode Sensor14 are both electrically connected to the second touch signal line TX2. The fifth touch electrode Sensor21 and the sixth touch electrode Sensor22 are both electrically connected to the third touch signal line TX3. The seventh touch electrode Sensor23 and the eighth touch electrode Sensor24 are both electrically connected to the fourth touch signal line TX4. In order to ensure that when one of the two touch electrodes electrically connected to the same touch signal line is working, the other one will not be in a passive state, the two touch electrodes are electrically connected to the voltage stabilizing signal line. As Figure 4As shown, a first voltage stabilizing transistor T31, a second voltage stabilizing transistor T41, a third voltage stabilizing transistor T32, a fourth voltage stabilizing transistor T42, a fifth voltage stabilizing transistor T33, a sixth voltage stabilizing transistor T43, a seventh voltage stabilizing transistor T34, and an eighth voltage stabilizing transistor T44 are respectively disposed between the first touch electrode Sensor11, the second touch electrode Sensor12, the third touch electrode Sensor13, the fourth touch electrode Sensor14, the fifth touch electrode Sensor21, the sixth touch electrode Sensor22, the seventh touch electrode Sensor23, the eighth touch electrode Sensor24 and the voltage stabilizing signal line LFD.

[0096] Specifically, as Figure 4 shown, the first touch electrode Sensor11, the second touch electrode Sensor12, the third touch electrode Sensor13, and the fourth touch electrode Sensor14 are disposed in the same column, the fifth touch electrode Sensor21, the sixth touch electrode Sensor22, the seventh touch electrode Sensor23, and the eighth touch electrode Sensor24 are disposed in the same column, the first touch electrode Sensor11, the second touch electrode Sensor12, the third touch electrode Sensor13, and the fourth touch electrode Sensor14 are respectively disposed in the same row as the fifth touch electrode Sensor21, the sixth touch electrode Sensor22, the seventh touch electrode Sensor23, and the eighth touch electrode Sensor24, the first touch electrode Sensor11 and the third touch electrode Sensor13 are spaced apart in two rows, and the second touch electrode Sensor12 and the fourth touch electrode Sensor14 are spaced apart in two rows.

[0097] Specifically, as Figure 4 shown, the gates of the first voltage stabilizing transistor T31, the third voltage stabilizing transistor T32, the fifth voltage stabilizing transistor T33, and the seventh voltage stabilizing transistor T34 are connected to the first voltage stabilizing control line TP-Mux-MSC1, the first electrodes of the first voltage stabilizing transistor T31, the third voltage stabilizing transistor T32, the fifth voltage stabilizing transistor T33, and the seventh voltage stabilizing transistor T34 are all connected to the voltage stabilizing signal line LFD, and the second electrodes of the first voltage stabilizing transistor T31, the third voltage stabilizing transistor T32, the fifth voltage stabilizing transistor T33, and the seventh voltage stabilizing transistor T34 are respectively connected to the first touch electrode Sensor11, the third touch electrode Sensor13, the fifth touch electrode Sensor21, and the seventh touch electrode Sensor23.

[0098] Specifically, as Figure 4As shown, the gates of the second voltage stabilizing transistor T41, the fourth voltage stabilizing transistor T42, the sixth voltage stabilizing transistor T43, and the eighth voltage stabilizing transistor T44 are connected to the second voltage stabilizing control line TP-Mux-MSC2. The first electrodes of the second voltage stabilizing transistor T41, the fourth voltage stabilizing transistor T42, the sixth voltage stabilizing transistor T43, and the eighth voltage stabilizing transistor T44 are all connected to the voltage stabilizing signal line LFD. The second electrodes of the second voltage stabilizing transistor T41, the fourth voltage stabilizing transistor T42, the sixth voltage stabilizing transistor T43, and the eighth voltage stabilizing transistor T44 are respectively connected to the second touch electrode Sensor12, the fourth touch electrode Sensor14, the sixth touch electrode Sensor22, and the eighth touch electrode Sensor24.

[0099] Specifically, as can be seen from the above embodiments, it is possible to achieve that the passive touch electrodes input signals at any time period by only setting two control signal lines, two voltage stabilizing control lines, and one voltage stabilizing signal line, avoiding touch and display abnormalities caused by the coupling of touch electrodes with other electrodes and / or signal lines, and reducing the border of the display panel.

[0100] In some embodiments, as Figures 2 to 5 shown, when the display panel 2 is configured to be in the display stage t1, the control signal line 232 and the voltage stabilizing control line 242 are configured to output an effective level, and the touch signal line 22 and the voltage stabilizing signal line LFD are configured to output a common signal;

[0101] When the display panel 2 is configured to be in the touch stage t2, one of the control signal line 232 and the voltage stabilizing control line 242 electrically connected to the same touch electrode 21 inputs an effective level, and the other inputs an invalid level. And among the two control signal lines 232 electrically connected to the touch electrodes 21 in the same column, one control signal line 232 inputs an effective level, and the other control signal line 232 inputs an invalid level. By making the touch signal line 22 and the voltage stabilizing signal line LFD output a common signal when the display panel 2 is configured to be in the display stage t1, a common signal can be input to the touch electrodes from both sides of the display area, making the common signals input by each touch electrode similar or even the same, and avoiding a large difference in the common signals between the proximal and distal ends from affecting the display effect. And when the display panel is in the touch stage, making one of the control signal line and the voltage stabilizing control line connected to the same touch electrode input an effective level and the other input an invalid level makes the touch electrode only input a voltage stabilizing signal or a touch signal, avoiding signal crosstalk. And among the two control signal lines connected to the touch electrodes in the same column, one control signal line inputs an effective level and the other control signal line inputs an invalid level, enabling one touch electrode to perform a touch function and the other touch electrode to input a voltage stabilizing signal.

[0102] Specifically, it can be understood that since both display and touch operations need to be performed within one frame of the display panel, to avoid abnormal display caused by too long a display interval due to long-term touch, the touch time period is divided into multiple touch stages, and the display time period is divided into multiple display stages. During each touch stage, some touch electrodes are used for touch operation, and the other part of the touch electrodes can input a regulated voltage signal. Figure 5 As shown in the figure, two touch stages t2 and one display stage t1 are cross-set, but the embodiments of the present application are not limited thereto, and multiple touch stages and multiple display stages can be cross-set.

[0103] Specifically, as Figures 3 to 5 shown, it can be seen that during the display stage t1, the first control signal line TP-Mux-SC1, the second control signal line TP-Mux-SC2, the first regulated voltage control line TP-Mux-MSC1, and the second regulated voltage control line TP-Mux-MSC2 all output valid levels (the valid level here is a high level), enabling each control transistor and each regulated voltage transistor to be turned on. The touch signal line 22 and the regulated voltage signal line LFD simultaneously input a common signal to each touch electrode to implement the display function. During one touch stage t2, the first control signal line TP-Mux-SC1 and the second regulated voltage control line TP-Mux-MSC2 output valid levels, the second control signal line TP-Mux-SC2 and the first regulated voltage control line TP-Mux-MSC1 output invalid levels, each touch signal line outputs a touch signal, and each regulated voltage signal line outputs a regulated voltage signal, so that some touch electrodes input touch signals and some touch electrodes input regulated voltage signals. During the other touch stage t2, the first control signal line TP-Mux-SC1 and the second regulated voltage control line TP-Mux-MSC2 output invalid levels, the second control signal line TP-Mux-SC2 and the first regulated voltage control line TP-Mux-MSC1 output valid levels, each touch signal line outputs a touch signal, and each regulated voltage signal line outputs a regulated voltage signal, so that some touch electrodes input touch signals and some touch electrodes input regulated voltage signals.

[0104] Specifically, it can be understood that during the touch stage t2, since the first control signal line TP-Mux-SC1, the second control signal line TP-Mux-SC2, the first voltage stabilization control signal line TP-Mux-MSC1, and the second voltage stabilization control signal line TP-Mux-MSC2 will turn on multiple transistors when they output valid levels, it will cause each touch signal line to input a touch signal to each touch electrode. If it is necessary to make a certain touch electrode work independently, the driving chip can be made not to receive the signals fed back from other touch electrodes, so as to realize the independent operation of a certain touch electrode. For example, when the first control signal line TP-Mux-SC1 and the second voltage stabilization control signal line TP-Mux-MSC2 output valid levels, and the second control signal line TP-Mux-SC2 and the first voltage stabilization control signal line TP-Mux-MSC1 output invalid levels, it will cause the first touch signal line TX1 to input a touch signal to the first touch electrode Sensor11, the second touch signal line TX2 to input a touch signal to the third touch electrode Sensor13, the third touch signal line TX3 to input a touch signal to the fifth touch electrode Sensor21, and the fourth touch signal line TX4 to input a touch signal to the seventh touch electrode Sensor23. If only the first touch electrode Sensor11 needs to perform touch, the driving chip can be made not to receive the signals on the third touch electrode Sensor13, the fifth touch electrode Sensor21, and the seventh touch electrode Sensor23, and the signals transmitted to these touch electrodes can be used as a voltage stabilization signal.

[0105] Specifically, it can be understood that when the voltage stabilization signal line LFD outputs a signal to the touch electrode, the signal of the corresponding touch electrode can be not received to avoid accidental touch. For example, when the voltage stabilization signal line LFD outputs a voltage stabilization signal to the second touch electrode Sensor12, the driving chip can be made not to receive the signal on the second touch electrode Sensor12 to avoid accidental touch.

[0106] In some embodiments, as Figure 5 shown, when the display panel 2 is configured to be in the touch stage t2, both the touch signal line 22 and the voltage stabilization signal line LFD output touch signals; or the voltage stabilization signal line LFD outputs a common signal, and the touch signal line 22 outputs a touch signal.

[0107] In some embodiments, as Figure 5As shown, the signal of the touch signal line 22 is the same as the signal of the voltage stabilizing signal line LFD, or when the display panel 2 is configured in the touch stage t2, the voltage stabilizing signal line LFD outputs a common signal. By making the voltage stabilizing signal line LFD output a stable common signal or touch signal, the non-operating touch electrodes can input stable signals, avoiding the passive influence of other signals on the touch electrodes or the influence of the touch electrodes on other signals, preventing accidental touches, preventing display defects, and improving touch stability.

[0108] Specifically, the voltage stabilizing signal line LFD can output a low potential signal or a pulse signal. The low potential signal can be the same as the common signal, the pulse signal can be the same as the touch signal, or the amplitude of the pulse signal can be lower than the amplitude of the pulse signal of the touch signal line. However, the embodiments of the present application are not limited thereto, and the amplitude of the pulse signal on the voltage stabilizing signal line can be greater than or equal to the amplitude of the pulse signal of the touch signal line.

[0109] In some embodiments, as Figures 2 to 4 shown, multiple touch electrodes 21 in the same row are electrically connected to different touch signal lines 22, and every two touch electrodes 21 in the same column are electrically connected to the same touch signal line 22. By electrically connecting each touch signal line to two touch electrodes, the number of touch signal lines can be reduced.

[0110] Specifically, each touch signal line in the embodiments of the present application is electrically connected to two touch electrodes, and a touch circuit is provided between the touch signal line and the touch electrode. The touch circuit includes a control transistor, and the conduction or cutoff of the circuit is controlled by the control transistor to realize the time-division driving of multiple touch electrodes electrically connected to the same touch signal line. Each touch electrode can work independently, thereby improving touch accuracy.

[0111] In some embodiments, as Figures 2 to 4 shown, the display panel 2 further includes a connection line 25 and a via 251 (since the connection line 25 is disposed in the via and connected to the touch electrode, the via is not shown). One end of the connection line 25 is connected to the touch circuit 23, the other end of the connection line 25 is connected to the common circuit 24, and the connection line 25 passes through the via 251 to connect the touch electrode 21. By connecting a connection line to the touch circuit, the common circuit, and the touch electrode, multiple traces do not need to be provided.

[0112] Specifically, Figure 3 、 Figure 4 takes an example that each connection line 25 is connected to a touch electrode 21 through three vias, but the embodiments of the present application are not limited thereto, and fewer vias or more vias can be provided.

[0113] In some embodiments, as Figures 2 to 4As shown, the touch circuit 23 is connected to the common circuit 24.

[0114] Specifically, when setting up the touch circuit and the common circuit, a touch electrode can be connected to the touch circuit and the common circuit through one trace, but the embodiments of the present application are not limited thereto, and the touch electrode can be connected to the touch circuit and the common circuit through two traces respectively.

[0115] Specifically, when inputting a signal to the voltage stabilization signal line through a driving chip, in order to prevent excessive voltage drop, the trace connected to the voltage stabilization signal line can be accessed from the left or right side of the display area, and the line width of the trace is larger than the line width of the connection line in the display area, so that the voltage drop of the signal output from the voltage stabilization signal line to the touch electrode is smaller.

[0116] Specifically, only some touch electrodes and touch signal lines are shown in the embodiments of the present application. For the design of other touch electrodes, touch signal lines and the components connected thereto, reference can be made to the design of the above-mentioned touch electrodes, touch signal lines and the components connected thereto.

[0117] Specifically, the first electrode is the source electrode and the second electrode is the drain electrode; or the first electrode is the drain electrode and the second electrode is the source electrode.

It can be understood that when there is no conflict among the embodiments, the embodiments can be combined. For example, the display panel includes a plurality of touch electrodes and a plurality of touch signal lines arranged in an array, and the touch circuit includes a plurality of control transistors and two control signal lines; wherein, the gates of the plurality of control transistors connecting the plurality of touch electrodes in the same row are connected to the same control signal line, the gates of the plurality of control transistors connecting the plurality of touch electrodes in adjacent rows are connected to different control signal lines, the gates of the plurality of control transistors connecting the touch electrodes in two rows arranged at intervals are connected to the same control signal line, the first electrodes of the plurality of control transistors connecting the plurality of touch electrodes in the same row are connected to different touch signal lines, the common circuit includes a voltage stabilization transistor, a voltage stabilization control line and a voltage stabilization signal line, the gate of the voltage stabilization transistor is connected to the voltage stabilization control line, the first electrode of the voltage stabilization transistor is connected to the voltage stabilization signal line, and the second electrode of the voltage stabilization transistor is connected to the touch electrode.
