Abstract

The invention provides an array substrate and a preparation method thereof. Through the array substrate, compared with the prior art, by forming a drain pattern layer in contact with the other end ofan active layer, and then forming a pixel electrode layer in contact with the drain pattern layer, conduction between the pixel electrode layer and the other end of the active layer is realized, in the embodiment, a pixel electrode layer in direct contact with the other end of the active layer is formed, the is, the drain pattern layer and the pixel electrode layer in the prior art are prepared atone time, As the contact resistance generate by the contact between the drain pattern layer and the pixel electrode lay in the prior art is avoided, the electrical conductivity is improved, and an annealing process carried out to increase the good contact between the drain pattern layer and the pixel electrode layer is omitted, thereby simplifying the process steps.

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] In an OLED display panel, the pixel electrode layer is in contact with the drain, and the drain is in contact with the active layer, so as to realize the conduction between the pixel electrode layer and the active layer, but there will be a contact resistance between the pixel electrode layer and the drain, so To reduce the conductivity between the pixel electrode layer and the drain, and to increase the good contact between the pixel electrode layer and the drain, it is necessary to perform annealing treatment on the pixel electrode layer and the drain, and the process is complicated. Contents of the invention [0003] The present invention mainly provides an array substrate and a preparation method thereof, aiming at solving the problem that the contact resistance between the pixel ele...
