Array substrate, display panel and display device

Abstract

The invention provides an array substrate, a display panel and a display device, the array substrate comprises sub-pixel units arranged in an array, and each sub-pixel unit comprises a drain electrode, a color resistor, a touch line and a pixel electrode; in a first direction, the color resistors of the sub-pixel units in the same row are the same in color, in a second direction, the color resistors of the sub-pixel units are provided with first concave parts, the sub-pixel units adjacent to the first concave parts are provided with second concave parts, the first concave parts and the secondconcave parts form first through holes, and the drain electrodes are electrically connected with the pixel electrodes through the first through holes; and the touch line extends along a second direction and is not overlapped with the vertical projection of the first through hole on the array substrate. According to the array substrate, the first through hole can be consistent with the preset size,the edge contour of the first through hole is clear, so that the connection stability of the drain electrode and the pixel electrode is ensured, the touch lines can be arranged on a flat surface, andthe uniformity of the line width of the touch lines is ensured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] As the demand for terminal display products such as medium and large-sized vehicle-mounted control systems, flat panels, monitors, and curved surface display products gradually increases, COA (Color Filter On Array) technology is more and more commonly used in display technology. COA integrates color photoresist into the film layer of the array substrate to form an array substrate with a color filter layer. In medium-to-large-size or curved display products, because of the difference in alignment accuracy between the array substrate and the counter substrate, edge or local misalignment is prone to occur, and the thermal process in the display panel manufacturing process will also cause damage to the graphics on the glass. deformation, so that the graphics on both sides of the substra...

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
