It is obvious that the described embodiments are a part of the embodiments of the present invention, not all embodiments, and all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without inventive efforts fall within the scope of the present invention.

a plurality of touch traces 140, touch electrodes 150, and a bridge structure 160;
the touch trace 140 is electrically connected to a corresponding one of the touch electrodes 150 through the bridge structure 160; along the extending direction of the scan line 110, a bridge structure 160 is disposed between at least two adjacent pixel units 130, and the bridge structure 160 and the pixel electrode 131 are disposed in the same layer; wherein, the pixel electrode adjacent to the bridge spanning structure 160 is the first type pixel electrode 1311; the pixel electrodes not adjacent to the bridge-spanning structure 160 are the second-type pixel electrodes 1312;
in the extending direction of the scan line 110, a distance L1 between two adjacent first-type pixel electrodes 1311 is greater than a distance L2 between the adjacent first-type pixel electrodes 1311 and the second-type pixel electrodes 1312, and is greater than or equal to a distance L3 between two adjacent second-type pixel electrodes 1312.
For example, in the design of the TED product, one touch electrode 150 may correspond to a plurality of rows and a plurality of columns of pixel units 130, and fig. 1 illustrates a case where only one touch electrode 150 corresponds to two rows and six columns of pixel units 130. One touch electrode 150 may correspond to at least one touch trace 140, and the electrical connection between the touch trace 140 and the touch electrode 150 is realized through at least one bridge structure 160, optionally, in order to realize stable voltage signals at different positions of the touch electrode 150, one touch electrode 150 may also be arranged corresponding to a plurality of touch traces 140, and the electrical connection between the touch trace 140 and the plurality of touch electrodes 150 is realized through the plurality of bridge structures 160, fig. 1 illustrates an example in which only one touch electrode 150 corresponds to one touch trace, and the electrical connection between the touch trace 140 and the touch electrode 150 is realized through one bridge structure 160. The bridge-crossing structure 160 is disposed between the third and fourth pixel electrodes, where the extending direction of the scan line 110 can be understood as a row direction, and the extending direction of the data line 120 can be understood as a column direction.
Specifically, as shown in fig. 1, the pixel electrodes adjacent to the bridge spanning structure 160 are first-type pixel electrodes 1311, the pixel electrodes not adjacent to the bridge spanning structure 160 are second-type pixel electrodes 1312, a distance L between two adjacent first-type pixel electrodes 1311 is greater than a distance L between two adjacent first-type pixel electrodes 1311 and second-type pixel electrodes 1312 along the extending direction of the scan line 110, and is greater than or equal to a distance L between two adjacent second-type pixel electrodes 1312, optionally, a distance L12 between two adjacent first-type pixel electrodes 1311 and second-type pixel electrodes 1312 along the extending direction of the scan line 110 is less than a distance L between two adjacent second-type pixel electrodes 1312 along the extending direction of the scan line 110. as shown in fig. 1, a distance L1 between two adjacent first-type pixel electrodes 1311 is greater than a distance L between two adjacent first-type pixel electrodes 1312 1 and second-type pixel electrodes 1312, and a distance 4933 between two adjacent first-type pixel electrodes 1311 and column electrodes 1315 is equal to a distance 465 between two adjacent first-type pixel electrodes 1311 and column electrodes 1312 similar to a distance between two adjacent second-type pixel electrodes 1313.
It should be noted that, since the distance L3 between two adjacent second-type pixel electrodes 1312 in the same column as two adjacent first-type pixel electrodes 1311 is equal to the distance L1 between the two adjacent first-type pixel electrodes 1311, it can be understood that in the preparation process of the array substrate, one touch electrode 150 may be electrically connected to the same touch trace 140 through a plurality of bridge structures 160, and a plurality of bridge structures 160 may be disposed between pixel electrodes 131 in different rows but in the same two columns, so to improve the preparation efficiency, even if the bridge structures 160 are not disposed between the pixel electrodes 131 in a certain row, in order to ensure higher preparation efficiency and light emitting efficiency of the display panel, the distance between two pixel electrodes in the two adjacent columns that do not include the bridge structures 160 is also set to be larger, that is, the distance L3 between two adjacent second-type pixel electrodes 1312 in the same column as two adjacent first-type pixel electrodes 1311 is equal to the distance L1 between two adjacent first-type pixel electrodes 1311.
Optionally, along the extending direction of the scan line 110, the distance L1 between two adjacent first-type pixel electrodes 1311 is greater than the distance L2 between the adjacent first-type pixel electrodes 1311 and second-type pixel electrodes 1312, and is greater than or equal to the distance L3 between two adjacent second-type pixel electrodes 1312, so that a larger distance can be maintained between the bridge-spanning structure 160 and the first-type pixel electrodes 1311, it is ensured that in the preparation process of the array substrate, the preparation of different film layers can be achieved without using a high-precision device, meanwhile, the risk of short circuit between the bridge-spanning structure 160 and the pixel electrodes 131 can be reduced, and the array substrate can work normally.

Optionally, the bridge-spanning structure 160 is arranged at the intersection of two adjacent rows and two adjacent columns of the first-class pixel electrodes 1311, so that a larger distance can be kept between the bridge-spanning structure 160 and the first-class pixel electrodes 1311, the process precision in the preparation process is reduced, the preparation difficulty is reduced, and the preparation efficiency is improved; meanwhile, the bridge structure 160 may be disposed at the intersection of at least one pixel electrode, so as to ensure that the influence on the aperture ratio of the display panel is small and the aperture ratio of the display panel is high.
