Problems solved by technology

[0004] The present invention provides an array substrate to solve the problem of the existing array substrate. Since the array substrate has a blind hole for arranging the camera, the alignment liquid will accumulate at the cone angle in the blind hole, resulting in the display after the subsequent box alignment. The technical problem of uneven brightness of the panel

Embodiment Construction

[0021] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0022] The present invention is aimed at the existing array substrate, because the array substrate has a blind hole for installing the camera, the alignment liquid will accumulate at the cone angle in the blind hole, resulting in uneven brightness of the display panel after the subsequent box alignment problem, this embodiment can solve this defect.

Abstract

An array substrate (100), comprising a substrate (10), a first interlayer insulating layer (30) provided with a first opening (301), a planarization layer (40) provided with a second opening (401), a second interlayer insulating layer (50) provided with a third opening (501), and a passivation layer (60) provided with a fourth opening (601), wherein the second opening (401), the third opening (501) and the fourth opening (601) sequentially increase in size and are in communication with each other to form a blind hole (70). By means of adjusting the positions and sizes of holes provided in a plurality of film layers at a blind hole in the array substrate, a taper angle at the blind hole becomes gradual, thereby avoiding accumulation of alignment liquid at the blind hole.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate. Background technique [0002] The current small-size display screens are developing rapidly. As people's requirements for screen-to-body ratios are getting higher and higher, in-plane digging screens have begun to appear in people's field of vision. In-plane hole digging technology mainly has two forms: blind hole and through hole. Among them, the through hole needs to get through the glass on both sides of the array substrate and the color filter substrate, while the blind hole is to keep the glass on both sides. Both kinds of holes are follow-up. Place the camera for use to achieve a high screen-to-body ratio. [0003] The existing blind hole design is to open a via hole on the interlayer insulating layer, flat layer, and passivation layer arranged in sequence, keep the bottom buffer layer without opening holes, open a large hole on the flat layer,...
