Array substrate, display panel and display device

Abstract

The invention relates to an array substrate, a display panel and a display device. The array substrate comprises a first substrate which comprises a trepanning area; and a second substrate, wherein the second substrate and the first substrate are oppositely arranged in an overlapped mode, the edge of at least one side of the second substrate is provided with an opening area, the opening area surrounds the trepanning area, and at least part of the edge of the trepanning area is tangent to at least part of the edge of the opening area. The array substrate is configured to be the first substrate and the second substrate which are overlapped up and down, the trepanning area is formed in the first substrate, and the opening area which can surround the trepanning area and is tangent to at least part of the edge of the opening area is formed in the second substrate, so that only one set of process design is needed, different product structure requirements of users can be met, the alignment problem during different special-shaped cutting is solved, the product machining precision is improved, the design pressure and the material pressure during product design and machining are greatly relieved, and the machining cost is effectively reduced.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] Existing full-screen mobile phones usually design a transparent area where the camera is placed in the upper middle of the screen. At present, the most popular area in this area is the round hole (Punch, commonly known as the blind hole), or the Notch (including the U-shaped groove commonly known as Qi Liuhai, the beauty sharp V-shaped grooves, drop-shaped grooves), with the diversification and diversification of mobile phones and other electronic products, users have more and more demands on product structures. higher cost. [0003] In addition, in the traditional product design process, the blind hole or Notch generally adopts the form of GOA (Gate Drive On Array, the gate drive circuit installed on the array substrate) unilateral drive, that is, the left and right GOAs respective...

Problems solved by technology

[0002] Existing full-screen mobile phones usually design a transparent area where the camera is placed in the upper middle of the screen. At present, the most popular area in this area is the round hole (Punch, commonly known as the blind hole), or the Notch (including the U-shaped groove commonly known as Qi Liuhai, the beauty sharp V-shaped grooves, drop-shaped grooves), with the diversification and diversification of mobile phones and other electronic products, users have more and more demands on product structures. higher cost

[0003] In addition, in the traditional product design process, the blind hole or Notch generally adopts the form of GOA (Gate Drive On Array, the gate drive circuit installed on the array substrate) unilateral drive, that is, the left and right GOAs respectively drive the gates of different rows. (Gate) pixels, when there is a problem with the first-level GOA or a row of gates (for example, the above-mentioned Notch is formed during special-shaped cutting), the pixels in this row will have no signal transmission, and the Y-Line half-section line will be defective.
