Problems solved by technology

[0004] However, since the pixel electrodes in the Micro-LED display panel are subjected to a large stress during the bending process, the light-emitting units bound together with the pixel electrodes are prone to peeling off due to the large stress during the bending process, thus Causes bad pixels to appear in the Micro-LED display panel, which has a negative impact on the display effect of the Micro-LED display panel

Abstract

This application discloses a array substrate and its preparation method, display panel. Among them, the first flexible substrate of the array substrate includes a foldable area, at least in the foldable areaThe drain or grid or the source layer of the same layer is set to reduce the distance of the distance of the first flexible substrate of the pixel, which reduces the distance between the pixel electrode distance and the neutral surface, and the binding position of the light emitting unit and the pixel electrode.The distance from the neutral surface; thereby reducing the bending stress of the binding position of the luminous unit and the pixel electrodes during the bending process, and then reduced the probability of peeling the light -emitting unit and pixel electrode during use, increasedThe stability and durability of the array substrate.

Description

technical field [0001] The present application relates to the technical field of display devices, and more specifically, to an array substrate, a manufacturing method thereof, and a display panel. Background technique [0002] With the continuous development of display technologies, flexible display panels have become one of the most concerned types of display panels. Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has become one of the mainstream technologies of flexible display panel due to its self-illumination, high contrast ratio and bendable characteristics. [0003] However, compared with traditional liquid crystal (Liquid Crystal Display, LCD) display panels, OLED display panels are more expensive and difficult to manufacture. In order to reduce the difficulty of manufacturing flexible display panels, Micro-LED display panels came into being. On the basis of being bendable, Micro-LED display panels have the advantages of lower manufac...
