Abstract

The invention discloses a method for preparing an array substrate, which belongs to the field of display technology, and aims to solve the technical problem that the preparation process of the array substrate is complicated in a touch screen adopting in-cell technology. The preparation method of the array substrate includes: sequentially forming a transparent conductive film and a metal film; using a photomask process, forming the transparent conductive film into an address electrode, and simultaneously forming the metal film into a metal structure that matches the address electrode , the mask process is a half-tone mask process or a gray tone mask process. The invention can be used in electronic devices such as mobile phones and tablet computers.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for preparing an array substrate. Background technique [0002] With the popularity of smart electronic products, capacitive touch screens are widely used in various electronic products such as mobile phones and tablet computers. At present, the more common capacitive touch screens include OGS (One Glass Solution), on-cell and in-cell technologies. Among them, due to its advantages in manufacturing process, in-cell technology has the advantages of lighter and thinner, better light transmission and more stable structure compared with OGS technology and on-cell technology. [0003] The inventors have found that in order to reduce the resistance of the address electrodes, a metal structure needs to be matched with the address electrodes in the touch screen adopting the in-cell technology. However, the appearance of the metal structure will increase the complexity...
