DETAILED DESCRIPTION

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0059] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0062] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0063] The display panel in the related art includes a substrate and a touch layer located on one side of the substrate, the touch layer includes touch electrodes, and the touch electrodes are electrically connected to the chip of the display panel. Since the touch electrodes themselves have a certain resistance, there is a large voltage drop from the end of the touch electrode connected to the chip to the end away from the chip, resulting in a large difference in touch performance between the end of the touch electrode connected to the chip and the end away from the chip, which ultimately affects the overall touch performance of the display panel.

[0064] In order to solve the above-mentioned technical problems, the inventor innovatively designed the following technical solutions, and the specific implementation solutions of the present application will be described in detail below in conjunction with the accompanying drawings. It should be noted that the defects existing in the solutions in the above-mentioned prior art are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above-mentioned technical problems and the solutions proposed in this embodiment below for the above-mentioned problems should all be the contributions made by the inventor to the present application in the process of invention and creation, and should not be understood as the technical content known to those skilled in the art.

[0065] See also Figure 1-Figure 3 This embodiment provides a display panel, which includes a substrate 1, a compensation layer 3 and a touch layer 2.

[0066] The compensation layer 3 is located on one side of the substrate 1 , and the compensation layer 3 includes a compensation electrode 31 ; the touch layer 2 is located on one side of the substrate 1 , and the touch layer 2 and the compensation layer 3 are different layers, and the touch layer 2 includes a touch electrode 201 , and the touch electrode 201 is connected in parallel with the compensation electrode 31 .

[0067] The substrate 1 may include a substrate and a plurality of drive units located on one side of the substrate, and each drive unit may include one or more semiconductor switch devices. The semiconductor switch device may be formed by the cooperation of a plurality of film layers in the substrate 1, for example, the semiconductor switch device may be a thin film transistor formed by the cooperation of a plurality of film layers.

[0068] See also Figure 2 and Figure 3 In some embodiments, the touch layer 2 is located on a side of the compensation layer 3 close to the substrate 1 .

[0069] See also Figure 4a , Figure 4b and Figure 5 In some other embodiments, the touch layer 2 is located on a side of the compensation layer 3 away from the substrate 1 .

[0070] Since the touch electrode 201 is connected in parallel with the compensation electrode 31 , the resistance of the touch electrode 201 can be greatly reduced, thereby improving the touch performance of the display panel as a whole.

[0071] Since the impedance of the touch electrode 201 is reduced as a whole, the resistance difference between the end of the touch electrode 201 connected to the chip 6 and the end connected away from the chip 6 can be reduced, thereby reducing the touch difference between the end connected to the chip 6 and the end connected away from the chip 6, thereby improving the touch uniformity of the display panel.

[0072] Based on the above design, this embodiment reduces the resistance of the touch electrode 201 by setting a compensation layer 3 that is different from the touch layer 2 and connecting the touch electrode 201 of the touch layer 2 in parallel with the compensation electrode 31 of the compensation layer 3, thereby improving the touch uniformity of the display panel and improving the touch performance of the display panel.

[0073] For some possible implementations, see again Figure 4a , Figure 4b and Figure 5 The display panel further includes an insulating layer 4 between the compensation layer 3 and the touch layer 2. Along the thickness direction of the substrate 1, the insulating layer 4 is provided with a first via hole 41 exposing at least a portion of the compensation electrode 31. The touch electrode 201 is connected in parallel with the compensation electrode 31 through the first via hole 41.

[0074] In the present application, the touch layer 2 is preferably located on the side of the compensation layer 3 away from the substrate 1. When the touch electrode 201 is formed, the touch electrode 201 is electrically connected to the compensation electrode 31 through the first via 41 provided on the insulating layer 4. In this way, the parallel connection between the touch electrode 201 and the compensation electrode 31 can be more easily achieved.

[0075] For some possible implementations, see again Figure 2 and Figure 3 The touch electrode 201 includes a first touch electrode 21 and a second touch electrode 22 . The first touch electrode 21 extends along a first direction X, and the second touch electrode 22 extends along a second direction Y. The first direction X and the second direction Y intersect.

[0076] Optionally, the display panel includes a display area, and the display panel further includes scan lines, and an extension direction of the scan lines in the display area includes a first direction X.

[0077] Optionally, the first direction X is perpendicular to the second direction Y.

[0078] Among them, the first touch electrode 21 includes a touch receiving electrode, and the second touch electrode 22 includes a touch sending electrode. The touch signal can be received through the first touch electrode 21, and the touch signal can be transmitted through the second touch electrode 22. The cooperation between the first touch electrode 21 and the second touch electrode 22 can realize the touch function of the display panel.

[0079] For some possible implementations, see Figure 6a , Figure 6b The compensation electrode 31 includes a plurality of first compensation electrodes 311 , the plurality of first compensation electrodes 311 are arranged along the first direction X, and the first touch electrode 21 is connected in parallel to the plurality of first compensation electrodes 311 .

[0080] In this embodiment, by connecting a plurality of first compensation electrodes 311 in parallel with the first touch electrodes 21 , the resistance of the first touch electrodes 21 can be further reduced, thereby further improving the touch performance and touch uniformity of the display panel.

[0081] Preferably, see again Figure 4a , Figure 4b and Figure 5 Along the thickness direction of the substrate 1 , the insulating layer 4 is provided with a first sub-via hole 411 exposing at least a portion of the first compensation electrode 311 , and the first touch electrode 21 is connected in parallel with the first compensation electrode 311 through the first sub-via hole 411 .

[0082] Optionally, there are multiple first sub-via holes 411 , and the multiple first sub-via holes 411 are arranged along the first direction X. In this way, it is easier to form the first sub-via holes 411 and realize the parallel connection between the first compensation electrode 311 and the first touch electrode 21 .

[0083] Optionally, a plurality of first compensation electrodes 311 are arranged at intervals.

[0084] The first via hole 41 includes a plurality of first sub-via holes 411. The first touch electrode 21 and the first compensation electrode 311 can be connected in parallel through the plurality of first sub-via holes 411. Since the plurality of first compensation electrodes 311 are arranged along the first direction X, the plurality of first sub-via holes 411 are also arranged along the first direction X. The plurality of first sub-via holes 411 provided on the insulating layer 4 make it easier for the first touch electrode 21 to be connected in parallel with the plurality of first compensation electrodes 311.

[0085] Preferably, see again Figure 4a , Figure 4b and Figure 5 , the orthographic projections of the plurality of first compensation electrodes 311 on the substrate 1 at least partially overlap with the orthographic projections of the first touch electrodes 21 on the substrate 1. In this way, it is easier to connect the first compensation electrodes 311 and the first touch electrodes 21 in parallel, and a planar capacitor is generated at the overlapping positions of the first compensation electrodes 311 and the first touch electrodes 21, thereby further improving the touch performance of the display panel.

[0086] Preferably, see again Figure 4a , Figure 4b and Figure 5, the orthographic projections of the plurality of first compensation electrodes 311 on the substrate 1 are located within the orthographic projections of the first touch electrodes 21 on the substrate 1. In this way, the overlapping area of ​​the first compensation electrodes 311 and the first touch electrodes 21 can be increased, thereby further improving the touch performance of the display panel.

[0087] Optionally, in some embodiments, please refer again to Figure 4a and Figure 5 The orthographic projection shape of the plurality of first compensation electrodes 311 on the substrate 1 is the same as the orthographic projection shape of the first touch control electrodes 21 on the substrate 1 .

[0088] It is worth noting that in this embodiment, the shape of the first compensation electrode 311 is the same as the shape of the first touch electrode 21, which does not mean that the shape of the first compensation electrode 311 is exactly the same as the shape of the first touch electrode 21. The shape of the first compensation electrode 311 is similar to the shape of the first touch electrode 21 and is also within the protection scope of this embodiment.

[0089] By setting the shape of the first compensation electrode 311 to be the same as the shape of the first touch electrode 21 , the overlapping area between the first compensation electrode 311 and the first touch electrode 21 can be greatly increased.

[0090] In other embodiments, please refer again to Figure 4b and Figure 5 The orthographic projection shapes of the first compensation electrodes 311 on the substrate 1 are different from the orthographic projection shapes of the first touch electrodes 21 on the substrate 1. In this way, the first compensation electrodes 311 can be set to different shapes according to actual needs, thereby increasing the flexibility of setting the shapes of the first compensation electrodes 311.

[0091] For some possible implementations, see again Figure 6a , Figure 6b The first touch electrode 21 includes a first end 7 and a second end 8 , the display panel further includes a chip 6 , and the first end 7 is electrically connected to the chip 6 .

[0092] For example, the first end 7 of the first touch electrode 21 can be electrically connected to the chip 6 through a connecting wire, and the second end 8 of the first touch electrode 21 is located at the end of the circuit connecting the chip 6 and the first touch electrode 21. Since the first touch electrode 21 has a resistor, and the signal of the chip 6 is transmitted from the first end 7 to the second end 8, the resistance of the second end 8 of the first touch electrode 21 is greater than the resistance of the first end 7, the charging time of the second end 8 is shorter than that of the first end 7, and the touch performance of the second end 8 is worse than that of the first end 7.

[0093] In this embodiment, the first touch electrode 21 is connected in parallel with the first compensation electrode 311 to reduce the resistance of the first touch electrode 21, thereby reducing the difference in touch performance between the first end 7 and the second end 8 of the first touch electrode 21 and improving the touch performance of the first touch electrode 21.

[0094] Preferably, see again Figure 6a , Figure 6b The area of ​​the orthographic projection of the first compensation electrode 311 located at the second end 8 on the substrate 1 is larger than the area of ​​the orthographic projection of the first compensation electrode 311 located at the first end 7 on the substrate 1 .

[0095] In this way, the resistance reduction amplitude of the second end 8 of the first touch electrode 21 can be greater than the resistance reduction amplitude of the first end 7, so that the resistance difference between the first end 7 and the second end 8 of the first touch electrode 21 is smaller, thereby reducing the touch difference between the first end 7 and the second end 8 of the first touch electrode 21 and improving the touch uniformity of the display panel.

[0096] Preferably, see again Figure 6a , Figure 6b , along the direction from the first end 7 to the second end 8, the area of ​​the positive projection of the plurality of first compensation electrodes 311 on the substrate 1 gradually increases.

[0097] In this way, the resistance of the first compensation electrode 311 connected in parallel with the first touch electrode 21 gradually decreases from the first end 7 to the second end 8 of the first touch electrode 21. Therefore, the overall resistance difference of the first touch electrode 21 can be made smaller, and ultimately the touch uniformity of the display panel can be further improved.

[0098] For some possible implementations, see Figure 7 The compensation electrode 31 includes a plurality of second compensation electrodes 312 , the plurality of second compensation electrodes 312 are arranged along the second direction Y, and the second touch electrode 22 is connected in parallel with the plurality of second compensation electrodes 312 .

[0099] In this embodiment, by connecting a plurality of second compensation electrodes 312 in parallel with the second touch electrodes 22 , the resistance of the second touch electrodes 22 can be further reduced, thereby further improving the touch performance and touch uniformity of the display panel.

[0100] Preferably, see Figure 8a , Figure 8b and Fig. 9 The display panel also includes an insulating layer 4 located between the compensation layer 3 and the touch layer 2. Along the thickness direction of the substrate 1, a second sub-via 412 exposing at least a portion of the second compensation electrode 312 is provided on the insulating layer 4. The second touch electrode 22 and the second compensation electrode 312 are respectively connected in parallel through the second sub-via 412.

[0101] Optionally, a plurality of second compensation electrodes 312 are arranged at intervals.

[0102] Optionally, there are multiple second sub-via holes 412 , and the multiple second sub-via holes 412 are arranged along the second direction Y. In this way, it is easier to form the second sub-via holes 412 and realize the parallel connection between the second touch electrode 22 and the second compensation electrode 312 .

[0103] The first via 41 includes a plurality of second sub-vias 412. The second touch electrode 22 and the second compensation electrode 312 can be connected in parallel through the plurality of second sub-vias 412. Since the plurality of second compensation electrodes 312 are arranged along the second direction Y, the plurality of second sub-vias 412 are also arranged along the second direction Y. The plurality of second sub-vias 412 arranged on the insulating layer 4 make it easier to connect the second touch electrode 22 and the plurality of second compensation electrodes 312 in parallel.

[0104] Preferably, see again Figure 7 The orthographic projections of the plurality of second compensation electrodes 312 on the substrate 1 at least partially overlap with the orthographic projections of the second touch electrodes 22 on the substrate 1; in this way, it is easier to connect the second compensation electrodes 312 and the second touch electrodes 22 in parallel, and at the same time, the overlapping positions of the second compensation electrodes 312 and the second touch electrodes 22 will generate a flat plate capacitor, thereby further improving the touch performance of the display panel.

[0105] Preferably, see again Figure 7 The orthographic projections of the plurality of second compensation electrodes 312 on the substrate 1 are located within the orthographic projections of the second touch electrode 22 on the substrate 1 ; thus, the overlapping area of ​​the second compensation electrodes 312 and the second touch electrode 22 can be increased, thereby further improving the touch performance of the display panel.

[0106] Preferably, see again Figure 8a and Fig. 9 The orthographic projection shape of the plurality of second compensation electrodes 312 on the substrate 1 is the same as the orthographic projection shape of the second touch control electrodes 22 on the substrate 1 .

[0107] It is worth noting that in this embodiment, the shape of the second compensation electrode 312 is the same as the shape of the second touch electrode 22, which does not mean that the shape of the second compensation electrode 312 is exactly the same as the shape of the second touch electrode 22. The shape of the second compensation electrode 312 is similar to the shape of the second touch electrode 22 and is also within the protection scope of this embodiment.

[0108] By setting the shape of the second compensation electrode 312 to be the same as the shape of the second touch electrode 22 , the overlapping area between the second compensation electrode 312 and the second touch electrode 22 can be greatly increased.

[0109] In other embodiments, please refer again to Figure 8b and Fig. 9 The orthographic projection shapes of the plurality of second compensation electrodes 312 on the substrate 1 are different from the orthographic projection shapes of the second touch electrodes 22 on the substrate 1. In this way, the second compensation electrodes 312 can be set to different shapes according to actual needs, thereby increasing the flexibility of setting the shapes of the second compensation electrodes 312.

[0110] For some possible implementations, see again Figure 7 The second touch electrode 22 includes a third end 9 and a fourth end 10 , and the third end 9 is electrically connected to the chip 6 .

[0111] For example, the third end 9 of the second touch electrode 22 can be electrically connected to the chip 6 through a connecting wire, and the fourth end 10 of the second touch electrode 22 is located at the end of the circuit connecting the chip 6 and the second touch electrode 22. Since the second touch electrode 22 has a resistor, and the signal of the chip 6 is transmitted from the third end 9 to the fourth end 10, the resistance of the fourth end 10 of the second touch electrode 22 is greater than the resistance of the third end 9, the charging time of the fourth end 10 is shorter than the charging time of the third end 9, and the touch performance of the fourth end 10 is worse than the touch performance of the third end 9.

[0112] In this embodiment, by connecting the second touch electrode 22 and the second compensation electrode 312 in parallel, the resistance of the second touch electrode 22 can be reduced, thereby reducing the difference in touch performance between the third end 9 and the fourth end 10 of the second touch electrode 22 and improving the touch performance of the second touch electrode 22.

[0113] Preferably, see again Figure 7 The area of ​​the orthographic projection of the second compensation electrode 312 located at the fourth end 10 on the substrate 1 is larger than the area of ​​the orthographic projection of the second compensation electrode 312 located at the third end 9 on the substrate 1 .

[0114] In this way, the resistance of the fourth end 10 of the second touch electrode 22 can be reduced to a greater extent than the resistance of the third end 9, so that the resistance difference between the third end 9 and the fourth end 10 of the second touch electrode 22 is smaller, thereby reducing the touch difference between the third end 9 and the fourth end 10 of the second touch electrode 22 and improving the touch uniformity of the display panel.

[0115] Preferably, see again Figure 7 , along the direction from the third end 9 to the fourth end 10 , the area of ​​the positive projection of the plurality of second compensation electrodes 312 on the substrate 1 gradually increases.

[0116] In this way, the resistance of the second compensation electrode 312 connected in parallel with the second touch electrode 22 gradually decreases from the third end 9 to the fourth end 10 of the second touch electrode 22. Therefore, the overall resistance difference of the second touch electrode 22 can be made smaller, and ultimately the touch uniformity of the display panel can be further improved.

[0117] For some possible implementations, see again Figure 2 and Figure 3 The display panel further includes a jumper wiring layer, the jumper wiring layer includes a jumper wiring 5 , the jumper wiring layer and the touch layer 2 are different layers, and the overlapping positions of the first touch electrode 21 and the second touch electrode 22 are staggered by the jumper wiring 5 .

[0118] The jumper wire 5 can facilitate the first touch electrode 21 and the second touch electrode 22 to be staggered at the overlapping position, so that the first touch electrode 21 and the second touch electrode 22 are not electrically connected.

[0119] In some embodiments, please refer again to Figure 4a , Figure 4b and Figure 5 The jumper wire 5 includes a first jumper wire 51 , the first touch electrode 21 includes a first touch unit 211 and a second touch unit 212 , and the first touch unit 211 is electrically connected to the second touch unit 212 through the first jumper wire 51 .

[0120] At the overlapping position of the first touch electrode 21 and the second touch electrode 22 , the first touch electrode 21 is divided into a first touch unit 211 and a second touch unit 212 which are spaced apart from each other, and the first touch unit 211 and the second touch unit 212 are electrically connected via a first jumper wire 51 .

[0121] In this way, the orthographic projections of the first touch unit 211 and the second touch unit 212 on the substrate 1 can be located outside the orthographic projection of the second touch electrode 22 on the substrate 1, and the orthographic projection of the first jumper trace 51 on the substrate 1 at least partially overlaps with the orthographic projection of the second touch electrode 22 on the substrate 1, so that the first touch electrode 21 and the second touch electrode 22 can be more easily staggered at the overlapping position.

[0122] Preferably, see again Figure 4a , Figure 4b and Figure 5 Along the thickness direction of the substrate 1 , the insulating layer 4 is provided with a second via hole 42 , and the first touch control unit 211 and the second touch control unit 212 are both electrically connected to the first jumper trace 51 through the second via hole 42 .

[0123] One first jumper wire 51 corresponds to two second vias 42, the first touch unit 211 is electrically connected to the first jumper wire 51 through one of the two second vias 42, and the second touch unit 212 is electrically connected to the first jumper wire 51 through the other of the two second vias 42. In this way, it is easier to electrically connect the first touch unit 211 and the second touch unit 212 through the first jumper wire 51.

[0124] Preferably, see again Figure 4a , Figure 4b , the number of the second via holes 42 is multiple, and the multiple second via holes 42 are arranged along the first direction X. Since the first touch electrodes 21 extend in the first direction X, the first touch units 211 and the second touch units 212 are arranged along the first direction X, and therefore, the multiple second via holes 42 connecting the first touch units 211 and the second touch units 212 are arranged along the first direction X.

[0125] In other embodiments, please refer again to Figure 8a , Figure 8b and Fig. 9 The jumper wire 5 includes a second jumper wire 52 , the second touch electrode 22 includes a third touch unit 221 and a fourth touch unit 222 , and the third touch unit 221 is electrically connected to the fourth touch unit 222 through the second jumper wire 52 .

[0126] At the overlapping position of the first touch electrode 21 and the second touch electrode 22 , the second touch electrode 22 is divided into a third touch unit 221 and a fourth touch unit 222 which are spaced apart from each other, and the third touch unit 221 and the fourth touch unit 222 are electrically connected via a second jumper wire 52 .

[0127] In this way, the orthographic projections of the third touch unit 221 and the fourth touch unit 222 on the substrate 1 can be located outside the orthographic projection of the first touch electrode 21 on the substrate 1, and the orthographic projection of the second jumper trace 52 on the substrate 1 at least partially overlaps with the orthographic projection of the first touch electrode 21 on the substrate 1, so that the third touch unit 221 and the fourth touch unit 222 can be more easily staggered at the overlapping position.

[0128] Along the thickness direction of the substrate 1, please refer to Figure 8a , Figure 8b and Fig. 9 A third via hole 43 is provided on the insulating layer 4 , and the third touch control unit 221 and the fourth touch control unit 222 are both electrically connected to the second jumper trace 52 through the third via hole 43 .

[0129] One second jumper wire 52 corresponds to two third vias 43, the third touch unit 221 is electrically connected to the second jumper wire 52 through one of the two third vias 43, and the fourth touch unit 222 is electrically connected to the second jumper wire 52 through the other of the two third vias 43. In this way, it is easier to electrically connect the third touch unit 221 and the fourth touch unit 222 through the second jumper wire 52.

[0130] Please see again Figure 8a , Figure 8b The number of the third via holes 43 is multiple, and the multiple third via holes 43 are arranged along the second direction Y.

[0131] Since the second touch electrodes 22 extend in the second direction Y, the third touch units 221 and the fourth touch units 222 are arranged along the second direction Y. Therefore, the plurality of third vias 43 connecting the third touch units 221 and the fourth touch units 222 are arranged along the second direction Y.

[0132] For some possible implementations, see again Figure 4a , Figure 4b and Figure 5 ,or Figure 8a , Figure 8b and Fig. 9 The jumper trace 5 and the compensation electrode 31 are on the same layer, and the orthographic projection of the jumper trace 5 on the substrate 1 is outside the orthographic projection of the compensation electrode 31 on the substrate 1. In this way, the compensation electrode 31 is formed at the same time as the jumper trace 5, so there is no need to specially set up a process for forming the compensation electrode 31, thereby reducing the cost of forming the compensation electrode 31.

[0133] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0134] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
