Array substrate, display panel and display device

Abstract

The present invention provides an array substrate, a display panel and a display device, which relate to the field of display technology, and are used to solve the problem of electrical connection failure in the display panel caused by electrochemical corrosion of metal wiring in the prior art, so as to help ensure the display panel. The display function is reliable. The array substrate includes: a base substrate, a metal trace, an insulating layer and a sacrificial circuit; an insulating layer is provided on the side of the metal trace facing the base substrate, and the insulating layer is provided with at least one via hole; A sacrificial circuit is provided on the side of the insulating layer facing the base substrate, and the sacrificial circuit is connected to the metal trace through the at least one via hole; wherein, the base substrate has an escape area, and the sacrificial circuit is provided with In the avoidance area, the sacrificial circuit is used to attract the electric charge accumulated by the metal trace, so that galvanic corrosion occurs in the avoidance area.

Description

Technical field [0001] The present invention involves the field of display technology, especially a formation of array, display panel and display device. Background technique [0002] With the rapid development of display technology, various types of display planes have gradually entered the market and have been widely used. For example, the display panel can be configured with various smart terminals such as mobile phones, tablets, television, smart wearable devices, and public places lobby to better realize human -computer interaction. [0003] At present, in the production process of display panels, such as in the production process of the array substrate of the display panel, in the process of vacuum film formation process such as physical gas deposition and dry etching, the charge is easily gathered in the metal membrane layer. After the metal membrane layer forms a metal wiring with specific graphics, electrochemical corrosion will occur during the subsequent wet process, r...

AI Technical Summary

Problems solved by technology

[0003] At present, in the production process of display panels, for example, in the production process of the array substrate of the display panel, in the process of vacuum film formation process such as physical vapor deposition, dry etching, etc., the charge is very easy to accumulate in the metal film layer. As a result, after the metal film layer forms metal traces with specific patterns, electrochemical corrosion will occur in the subsequent wet process, resulting in disconnection of the metal traces, which in turn leads to failure of electrical connections
