Problems solved by technology

Currently, the under-display camera technology mainly adopts through-hole and blind-hole structures. The through-hole design has poor appearance and low reliability, and cannot achieve a perfect full-screen design.
The blind hole structure also cannot display the camera area, and cannot achieve a true full screen

Abstract

The invention discloses a display panel and a preparation method thereof and a display device. The display panel comprises a display area including a transparent display area and a non-transparent display area surrounding the transparent display area. The display panel further comprises an array substrate in the display area. The display panel also comprises a first electrode which is arranged onthe array substrate. The thickness of the first electrode of the transparent display area is less than the thickness of the first electrode of the non-transparent display area, and the transmittance of the first electrode of the transparent display area is greater than or equal to 70%. According to the display panel and the display device, the transmittance of the transparent display area can be effectively increased. The preparation method of the display panel has simple steps and can reduce the number of times of using the light mask and the number of the light mask and effectively improvesthe production efficiency.

Description

Technical field [0001] The invention relates to the fields of displays and the like, in particular to a display panel, a preparation method thereof, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode) due to its light weight, self-luminous, wide viewing angle, low driving voltage, high luminous efficiency, low power consumption, fast response speed, etc., the application range is becoming more and more extensive, especially the flexible OLED display device has 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] Full screen is one of the goals of the development of OLED display technology. The under-screen camera technology can further increase the screen-to-body ratio on the existing technical level to achieve a perfect full screen design. Currently, the under-screen camera technology is mainly a through-hole and blind-hole structure. The thro...
