Abstract

The invention provides a fabrication method of an array substrate, the array substrate and a display device. The fabrication method of the array substrate comprises the steps of forming a display uniton one of two opposite surfaces of a substrate, forming a driving circuit on the other surface, and roughing edge regions of the two opposite surfaces and side surfaces connected with the edge regions of the two opposite surfaces to form a rough region; and forming a signal input end connected with the display unit and a metal wire of a signal output end of the driving circuit at the rough region. With the fabrication method of the array substrate, the array substrate and the display device, provided by the invention, the display effect of the display device can be ensured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a manufacturing method of an array substrate, an array substrate and a display device. Background technique [0002] The Micro-LED display panel has the advantages of ultra-high pixel count, ultra-high resolution, low energy consumption, and long life. Compared with Organic Light-Emitting Diode (OLED), it can The distance is reduced to um to further optimize the display effect, so Micro-LED display devices are becoming more and more popular in the market. [0003] At present, in order to realize the large-size display of the Micro-LED display device, it is necessary to splice multiple small-sized Micro-LED display panels together, wherein the front and back sides of each Micro-LED display panel need to be electrically connected. In the prior art, the way of realizing the electrical connection between the front and the back of the Micro-LED display panel is prone to disl...
