Abstract

The present disclosure relates to the field of display technology, and relates to an array substrate and its manufacturing method, a display panel, and a display device. The array substrate includes: a piezoelectric substrate, a pixel defining layer, and interdigital electrodes; the pixel defining layer is disposed on the piezoelectric substrate On the above, the pixel defining layer is formed with an opening area; the interdigital electrodes are oppositely arranged on both sides of the pixel defining layer on the piezoelectric substrate, and the oppositely arranged interdigital electrodes can be matched with the piezoelectric substrate. A standing acoustic surface wave including antinodes and wave nodes is formed on the substrate, the antinodes correspond to the positions of the opening area, and the wave nodes correspond to the positions of the pixel defining layer. In the array substrate provided by the present disclosure, when the light-emitting unit is formed in the hole area by the gas jet printing device, the gas material can be prevented from diffusing into the adjacent hole area.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to an array substrate and a manufacturing method thereof, a display panel and a display device. Background technique [0002] OLED (Organic Light-emitting Diode, Organic Light-emitting Diode) display is a new generation of display. OLED display has the advantages of good color contrast, active light emission, wide viewing angle, fast response speed, low energy consumption, light weight and flexibility. The principle of luminescence is to prepare an organic thin film between the anode and the cathode metal, and energize the two electrodes to realize the light emission of the thin film device. [0003] At present, there are mainly two manufacturing processes for OLED display devices, one is the FMM (Fine metal mask, Fine metalmask) evaporation process, and the other is the JP (Jet printing, Jet printing) process. Among them, the JP process can be divided into liquid jettin...
