Abstract

The invention provides an array substrate and a preparation method thereof. The array substrate comprises a substrate, a metal isolation layer and a protection layer, wherein the substrate comprises adisplay area and a non-display area; the metal isolation layer is located in the non-display area and defines an open pore area; and the protection layer at least wraps the side wall of the metal isolation layer. The protection layer at least covers the side wall of the metal isolation layer, and in the subsequent etching process of an electrode layer, a replacement reaction between an etching solution and the side wall of the metal isolation layer can be avoided, so that metal particles generated by the replacement reaction are prevented from influencing normal work of the array substrate, and poor display caused by the metal particles generated by the replacement reaction is further avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a preparation method thereof. Background technique [0002] With the rapid development of electronic equipment, users have higher and higher requirements for screen-to-body ratio, and the full-screen display of electronic equipment has attracted more and more attention from the industry. [0003] In traditional technologies, the screen-to-body ratio is generally increased by opening holes in the display panel. A camera, an earpiece, an infrared sensor, and the like can be arranged in the opening area of ​​the display panel. [0004] However, the traditional hole opening technology is likely to cause poor display of the display panel. Contents of the invention [0005] Based on this, it is necessary to provide an array substrate and a preparation method thereof to solve the problem in the conventional technology that hole openings easily cause p...
