Embodiment 1
[0058] Embodiment 1: a process flow of forming a first through hole in a display area on an array substrate.
[0059] In a specific implementation, the array substrate has at least two structures, the first structure and the second structure. Since the array substrate of the first structure and the array substrate of the second structure above, the main difference between the two lies in the first electrode layer and the second structure. Is the second electrode layer a pixel electrode or a common electrode, and in the display area, the first through hole is used to connect the pixel electrode and the source-drain metal layer, so the array substrate of the first structure and the array of the second structure In the substrate, the pattern of the first electrode layer and the pattern of the second electrode layer are different to some extent, but the other film layers, and the order and pattern of making each film layer are the same, and the manufacturing process is also basical...
Embodiment 2
[0108] Embodiment 2: a process flow of forming a second through hole in the display area on the array substrate.
[0109] In specific implementation, the same as the first embodiment above, the second embodiment also introduces the structure of forming the second through hole in the display area on the array substrate of the first structure and the array substrate of the second structure respectively. . Since the array substrate of the first structure and the array substrate of the second structure have a certain difference between the first electrode layer pattern and the second electrode layer pattern, and the other film layers and the manufacturing sequence of each film layer and The patterns and the like are the same, and the manufacturing process is also basically the same, therefore, the formation of the second through hole will not be described too much here. The difference in structure between the array substrate of the first structure and the array substrate of the s...
Embodiment 3
[0147] Embodiment 3: the process flow of forming the first through hole and the second through hole in the non-display area on the array substrate.
[0148]In a specific implementation, in the non-display area of the array substrate, whether it is the array substrate of the first structure or the array substrate of the second structure, the structures of the first through holes and the second through holes formed are the same. In addition, the first through hole and the second through hole may be arranged in the bonding area, and the specific manufacturing process flow is similar to that of Embodiment 1 and Embodiment 2, and reference may be made to the above two embodiments.
[0149] Such as Figure 21a As shown, it is a top view of the first through hole formed in the non-display area of the array substrate provided by the embodiment of the present invention; Figure 21b Shown, provided for the embodiment of the present invention Figure 21a Schematic diagram of the cr...
