Array substrate, display panel and display device

Abstract

The present invention provides an array substrate, a display panel and a display device, the array substrate includes sub-pixel units arranged in an array, and the sub-pixel units include drain electrodes, color resistors, touch lines and pixel electrodes; direction, the color resistance of the sub-pixel units in the same row is the same, along the second direction, the color resistance of the sub-pixel unit has a first recess, the sub-pixel unit adjacent to the first recess has a second recess, the The first concave portion and the second concave portion form a first through hole, and the drain electrode and the pixel electrode are electrically connected through the first through hole; the touch line extends along the second direction and is in the first through hole. The vertical projections of the array substrates do not overlap. The present invention can make the first through hole consistent with the preset size, and the edge contour of the first through hole is clear, thereby ensuring the stability of the connection between the drain electrode and the pixel electrode, and the touch line can be arranged on a relatively flat surface, thereby ensuring the touch line Line width uniformity.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an array substrate, a display panel and a display device. Background technique [0002] With the increasing demand for medium and large-sized vehicle central control systems, flat panels, monitors and other terminal display products and curved display products, COA (Color Filter On Array) technology is more and more widely used in display technology. COA is to integrate the color photoresist into the film layer of the array substrate to form an array substrate with a color filter layer. In medium-to-large-sized or curved display products, due to the difference in alignment accuracy between the array substrate and the opposite substrate, edge or local dislocation is prone to occur, and the thermal process in the display panel manufacturing process will also cause damage to the pattern on the glass. The deformation causes the phenomenon that the patterns on both side...

AI Technical Summary

Problems solved by technology

[0003] However, there are still some problems in the existing COA technology itself, such as the process compatibility between the photoresist and each metal film layer, and the difficulty in opening holes on the photoresist, etc. It is urgent for those skilled in the art to propose solutions
