Array substrate manufacturing method, array substrate and display device

Abstract

The invention provides an array substrate manufacturing method, an array substrate and a display device. The array substrate manufacturing method includes the steps of forming patterns of an active layer, a grid insulation layer, a grid and a grid line with the once layout technology; forming a passivation layer on a substrate where the active layer, the grid insulation layer, the grid and the grid line are formed, and forming a via hole in the passivation layer with the once layout technology; forming patterns of a data line, a source, a drain and a pixel electrode on the substrate where the passivation layer is formed with the once layout technology, wherein the drain makes contact with the active layer through the via hole. By means of the array substrate manufacturing method, the array substrate and the display device, the number of times of the layout technology adopted in the low temperature polycrystalline silicon array substrate manufacturing technology process is decreased, the technology complexity is accordingly lowered, and the technology cost is reduced while the manufacturing technology time is shortened.

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] Compared with liquid crystal displays (LCDs), organic light emitting diode displays (OLEDs) have the advantages of fast response, light weight, bendability and wide viewing angles. The active matrix organic light emitting diode (AMOLED) has the advantages of small driving current and low power consumption, and is suitable for high-resolution displays. The active matrix organic light emitting diode architecture can be driven by amorphous silicon, polycrystalline silicon, oxide semiconductor or organic thin film transistors. Among them, low temperature polycrystalline silicon has a mobility as high as 100cm2 / V-s, and its high current characteristics are just in line with the stringent requirements of organic light emitting diodes. The low operating voltag...
