Abstract

The invention provides a display panel and a preparation method thereof, and a display device. The display panel comprises a display area, a wire changing area and a bending area which are divided inthe horizontal direction; the display panel sequentially comprises a substrate, a barrier layer, a buffer layer, an active layer, a first gate insulation layer, a first metal layer and a second gate insulation layer from bottom to top, and further comprises a first through hole, a second metal layer, a first organic layer, a second metal layer, an interlayer insulation layer and a third metal layer, wherein part of the third metal layer located in the display area penetrates the interlayer insulating layer and is electrically connected to the second metal layer. The display panel has the technical effects that the bending performance of the display panel is improved, the circuit voltage drop is reduced, and the brightness uniformity of the display panel is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode) is widely used due to its light weight, self-illumination, wide viewing angle, low driving voltage, high luminous efficiency, low power consumption, and fast response, especially flexible OLED display devices. The characteristics of being bendable and easy to carry have become the main field of research and development in the field of display technology. [0003] At present, high-end mobile phones have high requirements on brightness uniformity. How to improve the brightness uniformity of the screen is the key direction of the development of major manufacturers. Contents of the invention [0004] The purpose of the present invention is to solve the technical problem that the brightness uniformity of the existing display panel cannot meet high requirements...
