[0051] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0052] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a partial top view of a common display panel at present, Figure 2 is Figure 1 is a partial enlarged view of the display panel shown at A, Figure 3 is Figure 2 is a film layer structure schematic diagram of the display panel shown at B-B'. The display panel 00 can include a driving back plate 01, a plurality of light emitting devices 02 located at one side of the driving back plate, an encapsulation layer 03 for encapsulating the plurality of light emitting devices 02, and a touch electrode layer 04 located at a side of the encapsulation layer 03 away from the driving back plate 01.

[0053] Here, the touch electrode layer 04 is usually a grid-shaped metal electrode layer. That is, the touch electrode layer 04 has a plurality of grid holes 04a, and the plurality of grid holes 04a can correspond to the plurality of light emitting devices 02 one by one, and the orthographic projection of each light emitting device 02 on the driving backboard 01 can be within the orthographic projection of the corresponding grid hole 04a on the driving backboard 01.

[0054] Here, the touch electrode layer 04 can usually include a plurality of touch driving electrodes 041 and a plurality of touch sensing electrodes 042. The touch driving electrodes 041 and the touch sensing electrodes 042 can both have grid holes 04a, and the touch driving electrodes 041 and the touch sensing electrodes 042 are arranged in the same layer and are made of the same material. In order to ensure that the touch driving electrodes 041 and the touch sensing electrodes 042 will not be short-circuited, a plurality of partition openings 04b need to be arranged between the touch driving electrodes 041 and the touch sensing electrodes 042.

[0055] However, since the touch electrode layer 04 is made of a metal material, the reflectivity of the touch electrode layer 04 to ambient light is usually high, and the reflectivity of the partition openings 04b arranged in the touch electrode layer 04 to ambient light is low. Therefore, when the touch driving electrodes 041 and the touch sensing electrodes 042 are partitioned by arranging the partition openings 04b therebetween, under the irradiation of ambient light when the display panel does not display a picture, grid-shaped dark lines can appear on the display panel 00, which are mainly distributed between the touch driving electrodes 041 and the touch sensing electrodes 042, resulting in low reliability of the display panel 00.

[0056] In the related art, in order to reduce the dark line phenomenon presented by the display panel when it does not display a picture under the irradiation of ambient light, it is necessary to arrange uniform partition openings in the interior of the touch driving electrodes 041 and the touch sensing electrodes 042. Such a design will cause the resistance of the touch driving electrodes 041 and the resistance of the touch sensing electrodes 042 to increase, which will further cause the touch effect of the display panel 00 to deteriorate.

[0057] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 4 is a top view of a display panel provided by an embodiment of the present application, Figure 5 is Figure 4 a partial enlarged view of the display panel at C shown in FIG. 1, Figure 6 is Figure 5 a partial enlarged view of the display panel at D shown in FIG. 1, Figure 7 is Figure 6A schematic view of a film layer structure of the display panel at E-E'. The display panel 000 can include a driving backboard 100, a plurality of light emitting devices 200, an encapsulation layer 300, a touch electrode layer 400, and an auxiliary trunk 500.

[0058] The plurality of light emitting devices 200 in the display panel 000 can be located on one side of the driving backboard 100, and the plurality of light emitting devices 200 are arranged in an array on the driving backboard 100. Here, each light emitting device 200 can be electrically connected with the driving backboard 100, and the driving backboard 100 can drive the light emitting device 200 to emit light.

[0059] The encapsulation layer 300 in the display panel 000 can be located on a side of the plurality of light emitting devices 200 away from the driving backboard 100. Here, the encapsulation layer 300 is used to encapsulate each light emitting device 200 to prevent water and oxygen in the external environment from corroding the light emitting layer in the light emitting device 200, so that the service life of the light emitting device 200 is higher.

[0060] The touch electrode layer 400 in the display panel 000 can be located on a side of the encapsulation layer 300 away from the driving backboard 100. Here, the touch electrode layer 400 can be a grid-shaped metal electrode layer. For example, the touch electrode layer 400 has a plurality of grid holes 400a corresponding to the plurality of light emitting devices 200 one by one, and the orthographic projection of each light emitting device 200 on the driving backboard 100 can be located in the orthographic projection of the corresponding grid hole 400a on the driving backboard 100. That is, the orthographic projection of the touch electrode layer 400 on the driving backboard 100 does not coincide with the orthographic projection of the light emitting device 200 on the driving backboard 100. Therefore, even if the material of the touch electrode layer 400 uses a light-proof metal material, it can be ensured that the touch electrode layer 400 will not block the light emitting device 200, so that the light emitted by the light emitting device 200 can be transmitted from the corresponding grid hole 400a of the touch electrode layer 400, and thus the display panel 000 can normally display a picture.

[0061] In this application, as Figure 4As shown, the touch electrode layer 400 can include a plurality of touch driving electrodes 401 and a plurality of touch sensing electrodes 402. Here, by cooperation of the touch driving electrodes 401 and the touch sensing electrodes 402, a capacitance change of an area where a user touches the display panel 000 can be detected to locate a position of the touch area through the capacitance change. The touch driving electrodes 401 and the touch sensing electrodes 402 can each have a grid hole 400a, and the touch driving electrodes 401 and the touch sensing electrodes 402 are disposed in the same layer and are of the same material. It should be noted that the same layer and the same material of the two structures in the embodiments of the present application means that the two structures are formed by the same patterning process. For example, the touch driving electrodes 401 and the touch sensing electrodes 402 are formed by one patterning process. The one patterning process can include photoresist coating, exposure, development, etching, and photoresist stripping.

[0062] As shown in FIG. 4, the touch electrode layer 400 can include a plurality of touch driving electrodes 401 and a plurality of touch sensing electrodes 402. Here, by cooperation of the touch driving electrodes 401 and the touch sensing electrodes 402, a capacitance change of an area where a user touches the display panel 000 can be detected to locate a position of the touch area through the capacitance change. The touch driving electrodes 401 and the touch sensing electrodes 402 can each have a grid hole 400a, and the touch driving electrodes 401 and the touch sensing electrodes 402 are disposed in the same layer and are of the same material. It should be noted that the same layer and the same material of the two structures in the embodiments of the present application means that the two structures are formed by the same patterning process. For example, the touch driving electrodes 401 and the touch sensing electrodes 402 are formed by one patterning process. The one patterning process can include photoresist coating, exposure, development, etching, and photoresist stripping. Figure 5 and Figure 6 As shown, in order to prevent the problem of short circuit between the touch driving electrodes 401 and the touch sensing electrodes 402 disposed in the same layer, a plurality of partition openings 400b need to be arranged in the touch electrode layer 400, and the partition openings 400b need to be distributed between the touch driving electrodes 401 and the touch sensing electrodes 402 to partition the touch driving electrodes 401 and the touch sensing electrodes 402 through the partition openings 400b.

[0063] The auxiliary trunk line 500 in the display panel 000 can be located in the grid hole 400a of the touch electrode layer 400, at least one end of the auxiliary trunk line 500 can be connected with the inner wall of the grid hole 400a, and the auxiliary trunk line 500 has an auxiliary partition opening 500a. In one possible implementation, the two ends of the auxiliary trunk line 500 can be respectively connected with the inner walls of the corresponding grid holes 400a, in which case the auxiliary partition opening 500a can be located on the auxiliary trunk line 500. In another possible implementation, one end of the auxiliary trunk line 500 is connected with the inner wall of the corresponding grid hole 400a, and the other end of the auxiliary trunk line 500 is arranged separately from the inner wall of the grid hole 400a, in which case the auxiliary partition opening 500a can be located between the other end of the auxiliary trunk line 500 and the inner wall of the corresponding grid hole 400a.

[0064] It should be noted that at least part of the plurality of mesh holes 400a of the touch electrode layer 400 can be provided with the auxiliary trunk 500. Here, in one possible case, each mesh hole 400a of the touch electrode layer 400 is provided with the auxiliary trunk 500; in another possible case, part of the mesh holes 400a of the touch electrode layer 400 are provided with the auxiliary trunk 500, and the other part of the mesh holes 400a can not be provided with the auxiliary trunk 500, and these mesh holes 400a provided with the auxiliary trunk 500 need to be uniformly distributed in the touch electrode layer 400. Therefore, the plurality of auxiliary isolation ports 500a in the display panel 000 can be uniformly distributed in the touch electrode layer 400.

[0065] In the embodiment of the present application, due to the reflectivity of the auxiliary isolation port 500a of the auxiliary trunk 500 to the ambient light, which is approximately equal to the reflectivity of the isolation port 400b in the touch electrode layer 400 to the ambient light, and the plurality of auxiliary isolation ports 500a in the display panel 000 can be uniformly distributed in the touch electrode layer 400. Therefore, under the irradiation of the ambient light when the display panel 000 does not display a picture, the probability of presenting a grid-shaped dark line on the display panel 000 can be effectively reduced, and thus the reliability of the display panel 000 can be improved.

[0066] In addition, the present application sets an additional auxiliary trunk 500 with an auxiliary isolation port 500a in the mesh hole 400a, and does not additionally set an isolation port in the touch driving electrode 401 and the touch sensing electrode 402 in the touch electrode layer 400, so that the resistance of the touch driving electrode 401 and the resistance of the touch sensing electrode 402 are not increased, so that the touch effect of the display panel 000 is not affected, and the reliability of the display panel 000 is further improved.

[0067] In summary, the display panel provided by the embodiment of the present application comprises: a driving backboard, a plurality of light emitting devices, an encapsulation layer, a touch electrode layer, and an auxiliary trunk. Due to the reflectivity of the auxiliary isolation port of the auxiliary trunk to the ambient light, which is approximately equal to the reflectivity of the isolation port in the touch electrode layer to the ambient light, and the plurality of auxiliary isolation ports in the display panel can be uniformly distributed in the touch electrode layer. Therefore, under the irradiation of the ambient light when the display panel does not display a picture, the probability of presenting a grid-shaped dark line on the display panel can be effectively reduced, and thus the reliability of the display panel can be improved. In addition, the present application sets an additional auxiliary trunk with an auxiliary isolation port in the mesh hole, and does not additionally set an isolation port in the touch driving electrode and the touch sensing electrode in the touch electrode layer, so that the resistance of the touch driving electrode and the resistance of the touch sensing electrode are not increased, so that the touch effect of the display panel is not affected, and the reliability of the display panel is further improved.

[0068] In the embodiments of the present application, please refer to Figure 8 , Figure 8 is another partial top view of a display panel provided by the embodiments of the present application. The touch electrode layer 400 in the display panel 000 can include a plurality of first trunk lines 410 extending along a first direction X, and a plurality of second trunk lines 420 extending along a second direction Y. Here, the first direction X is the column arrangement direction of the plurality of light emitting devices 200, and the second direction Y is the row arrangement direction of the plurality of light emitting devices 200. Among them, the plurality of first trunk lines 410 can be arranged in parallel and all extend along the first direction X, and the plurality of second trunk lines 420 are arranged in parallel and all extend along the second direction Y. That is, in the drawings in the present application, the horizontal lines are the first trunk lines 410, and the vertical lines are the second trunk lines 420.

[0069] To this end, the plurality of first trunk lines 410 and the plurality of second trunk lines 420 are used to enclose a plurality of grid holes 400a in the touch electrode layer 400. For example, two adjacent first trunk lines 410 and two adjacent second trunk lines 420 can enclose a rectangular frame with a grid hole 400a, and the orthographic projection of each light emitting device 200 on the driving backplate 100 can be located in the area enclosed by the orthographic projection of the rectangular frame on the driving backplate 100.

[0070] In the present application, the touch driving electrodes 401 and the touch sensing electrodes 402 in the touch electrode layer 400 each include a portion of the first trunk lines 410 and a portion of the second trunk lines 420. It should be noted that the first trunk lines 410 and the second trunk lines 420 can be disposed in the same layer and have the same material. In order to ensure that there is no short circuit phenomenon between the adjacent touch driving electrodes 401 and the touch sensing electrodes 402, a plurality of partition openings 400b can be provided on the first trunk lines 410 and the second trunk lines 420, so that the adjacent touch driving electrodes 401 and the touch sensing electrodes 402 can be disconnected through the partition openings 400b of the first trunk lines 410 and / or the partition openings 400b of the second trunk lines 420.

[0071] In the embodiments of the present application, the auxiliary trunk lines 500 in the display panel 000 can be disposed in the same layer as the touch electrode layer 400 and have the same material. That is, the first trunk lines 410, the second trunk lines 420 and the auxiliary trunk lines 500 are disposed in the same layer and have the same material. In this way, the first trunk lines 410, the second trunk lines 420 and the auxiliary trunk lines 500 can be formed at the same time through the same patterning process, which can effectively simplify the preparation difficulty of the display panel 000.

[0072] Optionally, the width of the grid hole 400a in the first direction X is greater than the width of the grid hole 400a in the second direction Y. In this case, the distance between the light emitting device 200 and the adjacent second main line 420 in the first direction X is greater than the distance between the light emitting device 200 and the adjacent first main line 410 in the second direction Y. In order to ensure that the auxiliary line 500 does not block the light emitted by the light emitting device 200, it is necessary to ensure that the extension direction of the auxiliary line 500 is parallel to the extension direction of the second main line 420. In this way, the auxiliary line 500 can be distributed between the second main line 420 and the light emitting device 200 in the first direction X. Since the distance between the light emitting device 200 and the adjacent second main line 420 in the first direction X is large, even if the auxiliary line 500 is distributed between them, the auxiliary line 500 will not block the light emitted by the light emitting device 200.

[0073] Optionally, as shown in FIG. 1, in the first direction X, at least one second main line 420 and at least one auxiliary line 500 are distributed between two adjacent light emitting devices 200. Figure 8

[0074] Optionally, as shown in FIG. 1, in the first direction X, at least one second main line 420 and at least one auxiliary line 500 are distributed between two adjacent light emitting devices 200.

[0075] Optionally, in the first direction X, for the two auxiliary lines 500 arranged side by side between the two adjacent light emitting devices 200, the positions of the auxiliary partition openings 500a in one auxiliary line 500 are staggered with the positions of the auxiliary partition openings 500a in the other auxiliary line 500 in the first direction X. For example, in the first direction X, the auxiliary partition openings 500a in one auxiliary line 500 are arranged in the first direction X, and the auxiliary partition openings 500a in the other auxiliary line 500 are arranged in the second direction Y. Figure 8 ​In the embodiment, the auxiliary partition opening 500a in one auxiliary trunk line 500 is located slightly above in the second direction Y, while the auxiliary partition opening 500a in the other auxiliary trunk line 500 is located slightly below in the second direction Y. In this case, since the distance between the two auxiliary trunk lines 500 arranged side by side is small, if the auxiliary partition openings 500a in the two auxiliary trunk lines 500 overlap in the first direction X, the display panel 000 may display a new dark line extending along the first direction X when the display panel 000 is not displaying an image and is exposed to ambient light. Therefore, when the auxiliary partition openings 500a in the two auxiliary trunk lines 500 arranged side by side are staggered in the first direction X, the appearance of a dark line extending along the first direction X on the display panel 000 can be effectively avoided, thereby further improving the reliability of the display panel 000.

[0076] In the embodiments of this application, Figure 8 As shown, the plurality of light-emitting devices 200 in the display panel 000 may include: a plurality of first-type light-emitting devices 201 and a plurality of second-type light-emitting devices 202. Here, the plurality of first-type light-emitting devices 201 may be arranged in a plurality of columns along a first direction X and in a plurality of rows along a second direction Y. The plurality of second-type light-emitting devices 202 may also be arranged in a plurality of columns along the first direction X and in a plurality of rows along the second direction Y. For example, the first direction X and the second direction Y may be perpendicular.

[0077] In the present application, two second-type light-emitting devices 202 are distributed between two adjacent first-type light-emitting devices 201 in the second direction Y. These two second-type light-emitting devices 202 can be arranged sequentially along the first direction X, and the two second-type light-emitting devices 202 are respectively configured to emit light of different colors. In one possible implementation, each first-type light-emitting device 201 can be configured to emit green light, that is, the first-type light-emitting device 201 is part of a green sub-pixel in the display panel 000; and the two second-type light-emitting devices 202 distributed between two adjacent first-type light-emitting devices 201 in the second direction Y are respectively configured to emit red light and blue light, that is, the two second-type light-emitting devices 202 are respectively part of a red sub-pixel and a blue sub-pixel in the display panel 000.

[0078] In this case, in the first direction X, the distance between two adjacent first light emitting devices 201 is greater than the distance between two adjacent second light emitting devices 202. Since the plurality of mesh holes 400a in the touch electrode layer 400 includes the first mesh hole A1 corresponding to the first light emitting device 201 and the second mesh hole A2 corresponding to the second light emitting device 202, the ratio of the area of the orthographic projection of the first light emitting device 201 on the driving backboard 100 to the area of the orthographic projection of the corresponding first mesh hole A1 on the driving backboard 100 can be greater than the ratio of the area of the orthographic projection of the second light emitting device 202 on the driving backboard 100 to the area of the orthographic projection of the corresponding second mesh hole A2 on the driving backboard 100. In this way, in the first direction X, the distance between the first light emitting device 201 and the first mesh hole A1 is greater than the distance between the second mesh hole A2 and the second light emitting device 202.

[0079] In this application, the auxiliary trunk 500 in the display panel 000 can be distributed within the first mesh hole A1. For example, at least one auxiliary trunk 500 is distributed within each first mesh hole A1 in the touch electrode layer 400. In this way, the auxiliary trunk 500 can be smoothly embedded in the touch electrode layer 400, and at the same time, a certain distance between the auxiliary trunk 500 and the first light emitting device 201 in the first direction X is ensured to prevent the auxiliary trunk 500 from blocking the light emitted by the light emitting device 200.

[0080] It should be noted that the first mesh hole A1 and the second mesh hole A2 are both surrounded by the plurality of first main trunks 410 and the plurality of second main trunks 420. That is, in the first direction X, two second main trunks 420 are distributed on both sides of the first mesh hole A1; in the second direction Y, two first main trunks 410 are distributed on both sides of the first mesh hole A1. Similarly, in the first direction X, two second main trunks 420 are distributed on both sides of the second mesh hole A2; in the second direction Y, two first main trunks 410 are distributed on both sides of the second mesh hole A2.

[0081] In the embodiment of the present application, the plurality of first light emitting devices 201 in the display panel 000 have a plurality of arrangement directions, and the structure of the auxiliary trunk 500 distributed in the first mesh hole A1 is different in different arrangement modes. Therefore, the present application will be described by taking the following two possible implementation modes as examples:

[0082] The first possible implementation mode is as follows: Figure 8As shown, the plurality of first-type light emitting devices 201 in a row of the display panel 000 are distributed at equal intervals. That is, the distance between any two adjacent first-type light emitting devices 201 in a row of the display panel 000 is equal. For example, in the preparation process of the display panel 000, when the light emitting layer in the first-type light emitting device 201 is prepared by using an evaporation process, each evaporation opening in the mask plate used in the evaporation process can correspond to one first-type light emitting device 201, so as to evaporate the light emitting layer in the corresponding first-type light emitting device 201 through the evaporation opening.

[0083] In this case, in the first direction X, between every two adjacent first-type light emitting devices 201, there are at least one second main trunk line 420 and at least one auxiliary trunk line 500. It should be noted that in the first direction X, the number of auxiliary trunk lines 500 distributed between two adjacent first-type light emitting devices 201 can be one or two. Therefore, the following two cases are taken as examples for description.

[0084] The first case, as shown in Figure 8 When two auxiliary trunk lines 500 are distributed between two adjacent first-type light emitting devices 201 in the first direction X, the at least one second main trunk line 420 distributed between the two adjacent first-type light emitting devices 201 is located between the two auxiliary trunk lines 500 arranged side by side.

[0085] In this case, two auxiliary trunk lines 500 are distributed in the same first-type grid hole A1, and the first-type light emitting device 201 corresponding to the first-type grid hole A1 in the first direction X is distributed between the two auxiliary trunk lines 500. For example, for the two auxiliary trunk lines 500 distributed in the same first-type grid hole A1, in the first direction X, the distance between the two auxiliary trunk lines 500 and the first-type light emitting device 201 located therebetween is equal, and the distance between the two auxiliary trunk lines 500 and the adjacent second main trunk line 420 is equal.

[0086] Optionally, in the first direction X, for the two auxiliary trunk lines 500 arranged side by side between two adjacent first-type light emitting devices 201, the position of the auxiliary partition port 500a in one auxiliary trunk line 500 is staggered with the position of the auxiliary partition port 500a in the other auxiliary trunk line 500 in the first direction X.

[0087] The second case, as shown in Figure 9 , Figure 9This is a partial top view of another display panel provided by an embodiment of the present application. When an auxiliary trunk line 500 and a second trunk line 420 are distributed between two adjacent first-type light-emitting devices 201 in the first direction X, the auxiliary trunk lines 500 and the second trunk lines 420 can be arranged alternately in the first direction X. That is, in the first direction X, a second trunk line 420 will be distributed between two adjacent second trunk lines 420, and an auxiliary trunk line 500 will also be distributed between two adjacent second trunk lines 420.

[0088] In this case, an auxiliary trunk line 500 is distributed within the same first-type grid aperture A1. For example, in the first direction, the two sides of this auxiliary trunk line 500 are respectively a second trunk line 420 used to form this first-type grid aperture A1 and a first-type light-emitting device 201 corresponding to this first-type grid aperture A1, and the distance d1 between this auxiliary trunk line 500 and this first-type light-emitting device 201 is equal to the distance d2 between this first-type light-emitting device 201 and another second trunk line 420 used to form this first-type grid aperture A1.

[0089] Optional, such as Figure 9 As shown, in the first direction X, the second main line 420 between two adjacent first-type light-emitting devices 201 can be staggered with the second main line 420 between two adjacent second-type light-emitting devices 202, and the distance d3 between the second main line 420 between two adjacent first-type light-emitting devices 201 and the second main line 420 between two adjacent second-type light-emitting devices 202 is equal to the distance d4 between the auxiliary line 500 between two adjacent first-type light-emitting devices 201 and the second main line 420 between two adjacent second-type light-emitting devices 202. In this way, the second main lines 420 and the auxiliary lines 500 in the touch electrode layer 400 can be evenly distributed.

[0090] The second possible implementation is Figure 10 As shown, Figure 10is a partial top view of a display panel provided by another embodiment of the present application. In a row of the first light emitting devices 201 in the display panel 000, the distance between the first sub light emitting device 201a and the second sub light emitting device 201b is greater than the distance between the first sub light emitting device 201a and the third sub light emitting device 201c. Here, the first sub light emitting device 201a is any first light emitting device in the row of the first light emitting devices 201, and the second sub light emitting device 201b and the third sub light emitting device 201c are two first light emitting devices adjacent to the first sub light emitting device 201a in the row of the first light emitting devices 201. For example, in the preparation process of the display panel 000, when the evaporation process is used to manufacture the light emitting layer in the first light emitting device 201, each evaporation opening in the mask plate used in the evaporation process can correspond to two first light emitting devices 201 distributed adjacently, so as to evaporate the light emitting layer in the corresponding two first light emitting devices 201 through the evaporation opening. Here, the light emitting layers in the second sub light emitting device 201b and the third sub light emitting device 201c can be evaporated through the same evaporation opening.

[0091] In this case, the distance between the first sub light emitting device 201a and the second sub light emitting device 201b in the first direction X is large, and at least one second main trunk line 420 and at least one auxiliary trunk line 500 can be distributed between the first sub light emitting device 201a and the second sub light emitting device 201b in the first direction X. The distance between the first sub light emitting device 201a and the third sub light emitting device 201c in the first direction X is small, and only one second main trunk line 420 can be distributed between the first sub light emitting device 201a and the third sub light emitting device 201c in the first direction X.

[0092] For example, two auxiliary trunk lines 500 are distributed between the first sub light emitting device 201a and the second sub light emitting device 201b in the first direction X. Here, in the first direction X, the at least one second main trunk line 420 distributed between the first sub light emitting device 201a and the second sub light emitting device 201b is located between the two auxiliary trunk lines 500. In this case, the distance d5 between one of the auxiliary trunk lines 500 and the first sub light emitting device 201a in the first direction X is equal to the distance d6 between the other auxiliary trunk line 500 and the second sub light emitting device 201b in the first direction X.

[0093] Optionally, in the first direction X, for the two auxiliary trunk lines 500 located between the first sub-light-emitting device 201a and the second sub-light-emitting device 201b, the position of the auxiliary partition opening 500a in one auxiliary trunk line 500 is staggered with the position of the auxiliary partition opening 500a in the other auxiliary trunk line 500 in the first direction X. It should be noted that the purpose of this design can be referred to the corresponding content in the first possible implementation manner above, and will not be repeated here.

[0094] In the present application, there are various situations for the number of second main lines 420 distributed between the first sub-light emitting device 201a and the second sub-light emitting device 201b in the first direction X. Therefore, the present application embodiment is described with the following three situations as examples.

[0095] The first case, such as Figure 10 As shown, in the first direction X, when there is only one second main line 420 distributed between the first sub-light-emitting device 201a and the second sub-light-emitting device 201b, this second main line 420 can be collinear with the second main line 420 between two adjacent second-type light-emitting devices 202.

[0096] The second case, such as Figure 11 As shown, Figure 11 This is a partial top view of another display panel provided in another embodiment of the present application. In the first direction X, when there are two second main lines 420 distributed between the first sub-light-emitting device 201a and the second sub-light-emitting device 201b, these two second main lines 420 can be staggered with the second main lines 420 between two adjacent second-type light-emitting devices 202.

[0097] The third case, such as Figure 12 As shown, Figure 12 This is a partial top view of another display panel provided in another embodiment of the present application. In the first direction X, when there are three second main lines 420 distributed between the first sub-light-emitting device 201a and the second sub-light-emitting device 201b, the middle second main line 420 among the three second main lines 420 can be collinear with the second main line 420 between two adjacent second-type light-emitting devices 202, while the outer two second main lines 420 among the three second main lines 420 can be staggered with the second main lines 420 between two adjacent second-type light-emitting devices 202.

[0098] It should be noted that if there are multiple second main lines 420 distributed between the first sub-light-emitting device 201a and the second sub-light-emitting device 201b, for example, in the second or third case described above, the resistance of the touch drive electrodes 401 and the touch sensing electrodes 402 in the touch electrode layer 400 can be further reduced.

[0099] It should also be noted that in the above three cases, in the first direction X, the second main lines 420 and the auxiliary main lines 500 arranged between the first sub-light emitting device 201a and the second sub-light emitting device 201b can be distributed at equal intervals.

[0100] For the first and second possible implementations, in the touch electrode layer 400, at the junction of the adjacent touch driving electrodes 401 and the touch sensing electrodes 402, the second main line 420 has a partition 400b, and the second main line 420 with the partition 400b may be arranged adjacent to the auxiliary main line 500. In this case, Figure 13 As shown, Figure 13 This is a partial top view of another display panel provided by another embodiment of the present application. When a second main line 420, disposed adjacent to an auxiliary main line 500 in the first direction X, has a partition opening 400b, the position of the partition opening 400b of the second main line 420 is offset in the first direction from the position of the auxiliary partition opening 500a of the auxiliary main line 500. It should be noted that the purpose of this design is the same as the purpose of staggering the positions of the two auxiliary partition openings 500a in the first direction X in the above embodiment, and will not be further described here.

[0101] Optional, such as Figure 14 and Figure 15 As shown, Figure 14 is a top view of a display panel provided in another embodiment of the present application. Figure 15 yes Figure 14 A partial enlarged view of the display panel F is shown. The touch electrode layer 400 may include not only touch drive electrodes 401 and touch sensing electrodes 402, but also first dummy electrodes 403 located between adjacent touch drive electrodes 401 and touch sensing electrodes 402. The first dummy electrodes 403 may include a portion of the first main line 410 and a portion of the second main line 420. The first dummy electrodes 403 may be disconnected from the touch drive electrodes 401 by a partition 400b of the first main line 410 and / or a partition 400b of the second main line 420. The first dummy electrodes 403 may be disconnected from the touch sensing electrodes 402 by a partition 400b of the first main line 410 and / or a partition 400b of the second main line 420.

[0102] In this case, by arranging the first dummy electrode 403 between the adjacent touch driving electrodes 401 and touch sensing electrodes 402, the distance between the touch driving electrodes 401 and the touch sensing electrodes 402 can be effectively increased, so that the mutual capacity generated between the touch driving electrodes 401 and the touch sensing electrodes 402 is smaller, and thus the touch effect of the display panel 000 can be effectively improved.

[0103] Optionally, as shown in FIG. 4B, the display panel G can further include a touch electrode layer 400. The touch electrode layer 400 can include a plurality of touch driving electrodes 401 and a plurality of touch sensing electrodes 402. The touch driving electrodes 401 and the touch sensing electrodes 402 can be arranged in a matrix form. Figure 16 Figure 16 The touch electrode layer 400 can further include a second dummy electrode 404 in the isolation region 400c. The second dummy electrode 404 can include a portion of the first main line 410 and a portion of the second main line 420, and the second dummy electrode 404 is disconnected from the touch electrode 400d (i.e., the touch driving electrode 401 or the touch sensing electrode 402) through the disconnection of the break 400b of the first main line 410 and / or the break 400b of the second main line 420. Figure 14 In this case, by arranging the isolation region 400c in each touch electrode 400d, the coupling capacitance between the touch electrode 400d and the electrode layer (e.g., the cathode layer) in the display panel 000 can be effectively reduced, so as to further improve the touch effect of the display panel 000. In addition, by arranging the second dummy electrode 404 in the isolation region 400c, it can be ensured that the touch electrode layer 400 in the display panel 000 is uniformly distributed, and thus the reflectivity of each region of the display panel 000 can be approximately equal, so as to further improve the reliability of the display panel 000.

[0104] In the embodiment of the present application, in the touch electrode layer 400 of the display panel 000, the plurality of touch driving electrodes 401 can be arranged in a plurality of rows, and two adjacent touch driving electrodes 401 in each row of touch driving electrodes 401 can be connected through a first signal line. Similarly, the plurality of touch sensing electrodes 402 can be arranged in a plurality of columns, and two adjacent touch sensing electrodes 401 in each column of touch sensing electrodes 401 can be connected through a second signal line. Here, one of the first signal line and the second signal line can be arranged in the same layer and made of the same material as the touch driving electrodes 401 and the touch sensing electrodes 402, and the other of the first signal line and the second signal line can be a bridge signal line. The bridge signal line is arranged in a layer different from the touch electrode layer 400, and the first signal line and the second signal line need to be insulated at the intersection position. In this way, the short circuit phenomenon that occurs at the intersection of a row of touch driving electrodes 401 and a column of touch sensing electrodes 402 can be effectively avoided.

[0106] Optionally, as shown in FIG. 1, the display panel 000 can further include a pixel definition layer 600 located on one side of the driving backplate 100. The pixel definition layer 600 can have a plurality of pixel openings 600a corresponding to the plurality of light emitting devices 200 one by one. Each light emitting device 200 can be located in the corresponding pixel opening 600a. Figure 17 Figure 17 Optionally, as shown in FIG. 1, the display panel 000 can further include a pixel definition layer 600 located on one side of the driving backplate 100. The pixel definition layer 600 can have a plurality of pixel openings 600a corresponding to the plurality of light emitting devices 200 one by one. Each light emitting device 200 can be located in the corresponding pixel opening 600a.

[0107] Optionally, as shown in FIG. 1, the display panel 000 can further include a pixel definition layer 600 located on one side of the driving backplate 100.

Each light emitting device 200 can be located in the corresponding pixel opening 600a.

[0108] Optionally, as shown in FIG. 1, the display panel 000 can further include a pixel definition layer 600 located on one side of the driving backplate 100. The pixel definition layer 600 can have a plurality of pixel openings 600a corresponding to the plurality of light emitting devices 200 one by one. Each light emitting device 200 can be located in the corresponding pixel opening 600a.

[0109] Optionally, as shown in FIG. 1, the display panel 000 can further include a pixel definition layer 600 located on one side of the driving backplate 100. The pixel definition layer 600 can have a plurality of pixel openings 600a corresponding to the plurality of light emitting devices 200 one by one. Each light emitting device 200 can be located in the corresponding pixel opening 600a.

[0110] ​In summary, the display panel provided by the embodiment of the present application comprises a driving back plate, a plurality of light emitting devices, an encapsulation layer, a touch electrode layer and an auxiliary trunk. Due to the reflectivity of the auxiliary partition port of the auxiliary trunk to ambient light, which is approximately equal to the reflectivity of the partition port in the touch electrode layer to ambient light, and the plurality of auxiliary partition ports in the display panel can be uniformly distributed in the touch electrode layer. Therefore, under the irradiation of ambient light when the display panel does not display a picture, the probability of presenting a grid-shaped dark line on the display panel can be effectively reduced, and thus the reliability of the display panel can be improved. In addition, the present application sets an auxiliary trunk with an auxiliary partition port in the grid hole, and does not additionally set a partition port in the touch driving electrode and the touch sensing electrode in the touch electrode layer, so that the resistance of the touch driving electrode and the resistance of the touch sensing electrode are not increased, so that the touch effect of the display panel is not affected, and the reliability of the display panel is further improved.
