[0030] In recent years, mutual capacitance touch has been widely used in display panels. In traditional mutual capacitance touch panel design, as the size of the display panel increases, the resistance of the closed circuit formed by the coupling between the two types of electrodes will increase significantly, resulting in increased response time, increased scanning time, reduced reporting rate, and reduced touch performance.

[0031] See also Figures 1 to 8 , an embodiment of the present invention provides a display panel 100, comprising:

[0032] Panel body 200;

[0033] A touch electrode 400 layer 300 is located on one side of the panel body 200 , and the touch electrode 400 layer 300 includes a first circuit layer 310 , a second circuit layer 320 , and an interlayer insulating layer 330 located between the first circuit layer 310 and the second circuit layer 320 ;

[0034] The first circuit layer 310 includes a plurality of touch electrodes 400 , the second circuit layer 320 includes a plurality of resistance reduction units 500 , and at least one touch electrode 400 is arranged in parallel with the resistance reduction unit 500 .

[0035] The present invention provides a resistance reduction unit which is arranged in a different layer from the touch electrode, and connects the touch electrode and the resistance reduction unit in parallel, thereby reducing touch impedance, reducing response time, reducing scanning time, increasing reporting rate, and improving touch performance.

[0036] The technical solution of the present invention is now described in conjunction with specific embodiments.

[0037] In this embodiment, please refer to Figure 1 , Figure 2The display panel 100 includes a panel body 200, and a touch electrode 400 layer 300 located on one side of the panel body 200, the touch electrode 400 layer 300 includes a first circuit layer 310, a second circuit layer 320, and an interlayer insulating layer 330 located between the first circuit layer 310 and the second circuit layer 320; wherein the first circuit layer 310 includes a plurality of touch electrodes 400, the second circuit layer 320 includes a plurality of resistance reduction units 500, and at least one touch electrode 400 is arranged in parallel with the resistance reduction unit 500.

[0038] The resistance reduction unit 500 and the touch electrode 400 are arranged in different layers. Without changing the electrode arrangement of the circuit layer, the resistance reduction unit 500 and the touch electrode 400 are connected in parallel to reduce the resistance of the touch electrode 400, thereby reducing the touch impedance, reducing the response time, reducing the scanning time, increasing the reporting rate, and improving the touch performance.

[0039] In some embodiments, see Figure 1 , Figure 2 , the first circuit layer 310 also includes a plurality of first connecting lines 411, which are arranged along the first direction; the second circuit layer 320 also includes a plurality of second connecting lines 421, which are arranged along the second direction, and the material of the second connecting lines 421 is the same as the material of the resistance reduction unit 500; the interlayer insulating layer 330 includes a plurality of first vias 331 and a plurality of second vias 332; wherein the touch electrode 400 is a first electrode 410 or a second electrode 420, the first connecting line 411 is electrically connected to two adjacent first electrodes 410, and two adjacent second electrodes 420 are electrically connected to one second connecting line 421 through the first via 331, and at least one touch electrode 400 is arranged in parallel with the resistance reduction unit 500 through at least two second vias 332.

[0040] The first direction intersects with the second direction. For the convenience of description, the following description assumes that the first direction is perpendicular to the second direction. The first direction is the Y-axis direction, and the second direction is the X-axis direction.

[0041] The first direction may be a column direction, the second direction may be a row direction, adjacent first electrodes 410 are connected via the first connecting lines 411, the first electrodes 410 and the first connecting lines 411 in the same column direction form a first electrode 410 group, adjacent second electrodes 420 are jumper-connected via the second connecting lines 421, the second electrodes 420 and the second connecting lines 421 in the same row direction form a second electrode 420 group.

[0042] The types of the first electrode 410 and the second electrode 420 are not specifically limited, that is, the first electrode 410 is a driving electrode (TX) and the second electrode 420 is a sensing electrode (RX), or the first electrode 410 is a sensing electrode (RX) and the second electrode 420 is a driving electrode (TX), both of which are acceptable, forming a pattern of driving electrodes (TX) and sensing electrodes (RX), the driving electrodes provide excitation signals, and the sensing electrodes receive signals, thereby forming a two-dimensional plane coordinate of the touch control of the entire display panel 100.

[0043] The orthographic projection of the first connecting line 411 on the panel body 200 and the orthographic projection of the second connecting line 421 on the panel body 200 intersect, and the second connecting line 421 is connected to the second circuit layer 320 via a jumper, thereby avoiding the short circuit between the first connecting line 411 and the second connecting line 421, and realizing the electrical connection of the first electrodes 410 within the first electrode 410 group and the electrical connection of the second electrodes 420 within the second electrode 420 group.

[0044] The second connecting line 421 is arranged in the same layer as the resistance reduction unit 500, and the material of the second connecting line 421 is the same as that of the resistance reduction unit 500. The second connecting line 421 and the resistance reduction unit 500 can be formed simultaneously in the same process using one mask, which can not only reduce the touch impedance of the touch electrode 400, but also save one mask. By connecting the resistance reduction unit 500 and the touch electrode 400 in parallel, the resistance of the touch electrode 400 is reduced, thereby reducing the touch impedance, reducing the response time, reducing the scanning time, increasing the reporting rate, and improving the touch performance.

[0045] In some embodiments, due to the existence of the resistance reduction unit 500, the distance from the common electrode of the panel body 200 is also reduced, so that the capacitance in the circuit is slightly increased.

[0046] See also Figure 1 , Figures 3 to 6 , the first electrode 410 includes at least one first opening 610, or / and the second electrode 420 includes at least one second opening 620; or, the resistance reduction unit 500 includes at least one third opening 630; wherein, the orthographic projection of the first opening 610 on the second circuit layer 320 is located in the resistance reduction unit 500, the orthographic projection of the second opening 620 on the second circuit layer 320 is located in the resistance reduction unit 500, the orthographic projection of the third opening 630 on the first circuit layer 310 is located in the first electrode 410, or, the orthographic projection of the third opening 630 on the first circuit layer 310 is located in the second electrode 420.

[0047] Taking the first electrode 410 and the resistance reduction unit 500 corresponding to the first electrode 410 as an example, the first electrode 410 is set with a first opening 610, and the resistance reduction unit 500 includes a corresponding virtual opening 640; or the resistance reduction unit 500 is set with a third opening 630, and the first electrode 410 includes a corresponding virtual opening 640, and the virtual opening 640 has no corresponding electrode. This structure can reduce the capacitance between the resistance reduction unit 500 and the first electrode 410, thereby reducing the capacitance in the circuit, reducing the parasitic capacitance in the display panel 100, thereby reducing the electrical stress on the display panel 100 and improving the reliability of the display panel 100.

[0048] Taking the second electrode 420 and the resistance reduction unit 500 corresponding to the second electrode 420 as an example, the second electrode 420 is provided with a second opening 620, and the resistance reduction unit 500 includes a corresponding virtual opening 640; or the resistance reduction unit 500 is provided with a third opening 630, and the first electrode 410 includes a corresponding virtual opening 640, and the virtual opening 640 has no corresponding electrode. The principle and effect of this structure are the same as the structure of the first electrode 410 and the resistance reduction unit 500 corresponding to the first electrode 410.

[0049] In some embodiments, see Figure 1 , Figure 3 , Figure 5 The first circuit layer 310 is located on a side of the second circuit layer 320 away from the panel body 200 ; the resistance reduction unit 500 includes at least one third opening 630 .

[0050] The second circuit layer 320 is closer to the panel body 200, especially closer to the common electrode of the panel body 200, and has a greater impact on the overall display panel 100, especially on the common electrode. The resistance reduction unit 500 of the second circuit layer 320 is opened, the first electrode 410 includes a corresponding virtual opening 640, and the second electrode 420 includes a corresponding virtual opening 640. The virtual opening 640 has no corresponding electrode, and the effect of reducing parasitic capacitance is more obvious, thereby reducing the electrical stress on the display panel 100 and improving the reliability of the display panel 100.

[0051] In some embodiments, see Figure 2 , the orthographic projection of the resistance reduction unit 500 on the panel body 200 is located within the orthographic projection of the first electrode 410 on the panel body 200, and / or the orthographic projection of the resistance reduction unit 500 on the panel body 200 is located within the orthographic projection of the second electrode 420 on the panel body 200.

[0052] The effective overlapping area between the resistance reduction unit 500 and the first electrode 410, and between the resistance reduction unit 500 and the second electrode 420 is increased, so that the impedance of the touch electrode 400 is reduced, while the light extraction efficiency of the original design is not affected, the response time is reduced, the scanning time is reduced, the reporting rate is increased, the touch performance is improved, and the light extraction is not affected.

[0053] In some embodiments, the orthographic projection of the resistance reduction unit 500 on the panel body 200 coincides with the orthographic projection of the first electrode 410 on the panel body 200, and / or the orthographic projection of the resistance reduction unit 500 on the panel body 200 coincides with the orthographic projection of the second electrode 420 on the panel body 200.

[0054] The size of the resistance reduction unit 500 is the same as the size of the first electrode 410, and / or the size of the resistance reduction unit 500 is the same as the size of the second electrode 420, and when the effective overlapping area is maximum, that is, when the two have the same area pattern, the resistance value of the touch electrode 400 can be reduced by 50% without affecting the light output efficiency, thereby reducing the response time, reducing the scanning time, increasing the reporting rate, and improving the touch performance without affecting the light output.

[0055] In some embodiments, see Figure 7 , Figure 8 , at least one of the resistance reduction units 500 includes a first part 510 and a second part 520 that are connected and arranged; the orthographic projection of the first part 510 on the panel body 200 is located within the orthographic projection of the first electrode 410 on the panel body 200, or the orthographic projection of the first part 510 on the panel body 200 is located within the orthographic projection of the second electrode 420 on the panel body 200; the orthographic projection of the second part 520 on the panel body 200 is located outside the orthographic projection of the first electrode 410 on the panel body 200, and the orthographic projection of the second part 520 on the panel body 200 is located outside the orthographic projection of the second electrode 420 on the panel body 200.

[0056] In the top-view direction of the display panel 100, the resistance reduction unit 500 may have a second part 520 extending outside the first electrode 410 and the second electrode 420. The second part 520 can increase the area of ​​the resistance reduction unit 500, thereby increasing the parallel area with the touch electrode 400, reducing the touch organization of the touch electrode 400, reducing the response time, reducing the scanning time, increasing the reporting rate, and improving the touch performance without affecting the light output.

[0057] In some embodiments, the second portion 520 corresponds to a red sub-pixel of the display panel 100. The red sub-pixel has a longer wavelength and stronger penetration, which reduces the blocking effect on the display light.

[0058] In some embodiments, see Figure 1 , Figure 3 , Figure 5 The resistance reduction unit 500 includes the third opening 630 and the resistance reduction entity 650 , and the area of ​​the orthographic projection of the third opening 630 on the panel body 200 is smaller than the area of ​​the orthographic projection of the resistance reduction entity 650 on the panel body 200 .

[0059] The third opening 630 is used to reduce the capacitance value. When the effective parallel area is larger than the opening area of ​​the third opening 630, the resistance value and the capacitance value can be effectively balanced to a certain extent, thereby reducing the capacitance in the circuit and reducing the parasitic capacitance in the display panel 100, thereby reducing the electrical stress on the display panel 100 and improving the reliability of the display panel 100.

[0060] In some embodiments, the shapes of the first opening 610 , the second opening 620 , and the third opening 630 can be set according to actual conditions.

[0061] In some embodiments, see Figures 3 to 6 The edge shapes of the first opening 610, the second opening 620, and the third opening 630 are sawtooth shapes, which can increase the corresponding edge area, thereby reducing the capacitance in the circuit, and the parasitic capacitance in the display panel 100 is reduced, thereby reducing the electrical stress on the display panel 100 and improving the reliability of the display panel 100.

[0062] In some embodiments, the saw teeth may be triangular or rectangular.

[0063] In some embodiments, see Figure 1 The edge shape of the display panel 100 is a rectangle, including two long sides 110 and two short sides 120 ; the resistance reduction unit 500 is arranged in a direction parallel to the long sides 110 .

[0064] The line of the long side 110 is longer and the resistance is more likely to increase. Arranging the resistance reduction unit 500 in the direction of the long side 110 can more effectively reduce the touch impedance, reduce the response time, reduce the scanning time, increase the reporting rate, and improve the touch performance.

[0065] In some embodiments, in a direction from the edge of the display panel 100 to the center of the display panel 100 , the arrangement density of the resistance reduction units 500 gradually increases.

[0066] In the direction from the edge of the display panel 100 to the center of the display panel 100, the farther the distance from the integrated control element to the edge, the easier it is for the resistance to increase. The arrangement density of the resistance reduction unit 500 gradually increases, which can more effectively reduce the touch impedance, reduce the response time, reduce the scanning time, increase the reporting rate, and improve the touch performance.

[0067] In some embodiments, see Figure 1 The first electrode 410 and the second electrode 420 are connected to a printed circuit board 210 at the bottom of the display panel 100 , and an integrated circuit 220 is disposed on the printed circuit board 210 .

[0068] In some embodiments, the panel body 200 includes an array substrate, which includes an active layer located on the substrate, a first insulating layer located on the active layer, a gate layer located on the first insulating layer, a second insulating layer located on the gate layer, a source-drain layer located on the second insulating layer, and a third insulating layer located on the source-drain layer.

[0069] In some embodiments, the display panel 100 may be a liquid crystal display panel 100 or a self-luminous display panel 100 .

[0070] In some embodiments, the display panel 100 may be a liquid crystal display panel 100 , and the panel body 200 further includes a liquid crystal layer, a color filter layer, and upper and lower polarizing layers.

[0071] In some embodiments, the display panel 100 is a self-luminous display panel 100. The panel body 200 further includes a light-emitting device layer, the light-emitting device layer includes an anode layer located on the third insulating layer, a light-emitting material layer located on the anode layer, and a cathode layer located on the light-emitting material layer, the display panel 100 further includes a pixel definition layer disposed in the same layer as the light-emitting material layer, an encapsulation layer located on the light-emitting device layer, a polarizing layer located on the encapsulation layer, and a flexible cover plate located on the polarizing layer, and the display panel 100 further includes corresponding bonding layers located between the polarizing layer and the flexible cover plate, between the light-emitting device layer and the polarizing layer, and between the backplane and the substrate.

[0072] In some embodiments, the light-emitting device layer may include OLED (Organic Light-Emitting Diode) material, or may include Micro LED or Mini LED, which is not specifically limited here.

[0073] The present invention provides a resistance reduction unit which is arranged in a different layer from the touch electrode, and connects the touch electrode and the resistance reduction unit in parallel, thereby reducing touch impedance, reducing response time, reducing scanning time, increasing reporting rate, and improving touch performance.
