Abstract
A method for preparing an array substrate and an array substrate. The method for preparing an array substrate includes: depositing a first metal layer, an insulating layer, an active layer and a doping layer on the substrate; forming a photoresist on doping layer by using a first photomask process, and etching the photoresist to form a gate and a channel; depositing a second metal layer on the substrate; using the second photomask process to form the source-drain metal layer; depositing a passivation layer on the substrate; using the third photomask process to form a pixel electrode layer.
