Abstract

Embodiments of the invention provide a manufacturing method of an array substrate, the array substrate and a display device. The manufacturing method is characterized by firstly opening a hole on a first thin film transistor, then simultaneously performing hydrogen supplement processing for the first thin film transistor and a second thin film transistor, and opening a hole on the second thin filmtransistor, so that the first thin film transistor and the second thin film transistor can be repaired and compensated to different degrees through the hydrogen supplement processing respectively, wherein, because the hole is opened on the first thin film transistor firstly, the hydrogen supplementing effect of the first thin film transistor is weakened, in this way, the gradient of a current-voltage curve of the first thin film transistor can be properly reduced, a current difference caused by a threshold voltage difference is reduced, and electron mobility of the second thin film transistoris increased as much as possible, the charging electric quantity of a capacitor within the rated time is increased, the current difference between circuits is reduced, therefore, the display device can emit light uniformly, the occurrence probability of Mura is reduced, and the Mura effect is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for manufacturing an array substrate, the array substrate and a display device. Background technique [0002] Due to the rise of the global information society and the development of science and technology, the field of display technology is changing with each passing day, and there are more and more types of display technologies, such as traditional liquid crystal display technology, organic light-emitting diode (Organic Light-Emitting Diode, OLED) display technology , electrophoretic display technology, etc. Compared with other displays, the organic electroluminescent diode display has the advantages of self-luminous display, fast response speed, high brightness, wide viewing angle, etc., so that it has a wide application prospect. [0003] Although the organic electroluminescent diode display technology has the above-mentioned many advantages, in the existin...
