Abstract

The invention provides a display panel, a preparation method and a display device thereof. Specifically, the display panel comprises a polyimide substrate, and the polyimide substrate comprises polyimide and a polymer ultraviolet light absorber, the polyimide substrate comprises a through hole, and the through hole is matched with a preset non-display area of an under-screen camera. According to the technical scheme of the specification, the polymer ultraviolet light absorber is added into the polyimide substrate; the polyimide substrate can absorb part of ultraviolet light when a coating layer is removed through laser scanning, so that the laser energy actually absorbed by the polyimide is reduced, the polyimide is prevented from being carbonized under the action of high-energy laser, andthe technical effect of improving the transmittance of the display panel is achieved.

Description

technical field [0001] One or more embodiments of this specification relate to the field of display technology, and in particular to a display panel, a manufacturing method and a display device thereof. Background technique [0002] At present, in order to expand the area of ​​the displayable area and improve the visual experience of users, mobile phone manufacturers have sprung up a large number of notch screens and water drop screens in the market. Making the screen of a mobile phone into such a structure increases the area of ​​the display area, but the area above the camera still cannot be displayed. In order to solve this problem, the under-screen camera technology has emerged. The area above the under-screen camera can not only display normally, but also has a high transmittance, which can make the camera work normally and realize the function of taking pictures at the front. However, compared with the water drop screen and notch screen, the transmittance of the displ...
