Problems solved by technology

[0006] The polarizer used in OLED must be a circular polarizer. The circular polarizer is realized by a polarizer and a 1 / 4λ retardation film. The current traditional method is to attach the circular polarizer separately. If you encounter a folded OLED panel , this approach directly increases the thickness of the entire folding display, which is not conducive to screen folding, and the circular polarizer is prone to offset from the glass cover or OLED panel after folding

Abstract

The invention discloses a foldable ultra-thin glass protective cover plate with circular polarizing function, comprising ultra-thin glass, an ink frame is printed under the ultra-thin glass, an explosion-proof layer is coated under the ink frame, and an explosion-proof layer is printed under the explosion-proof layer. Nano-scale WGP polarizer, the lower part of the nano-scale WGP polarizer is coated with 1 / 4λ retardation film, the circular polarizer of the present invention does not need optical glue bonding, which not only integrates the functions of the circular polarizer, but also saves the optical glue The thickness and bonding process of the base material of the traditional circular polarizer make the function of the circular polarizer integrated with the glass cover, effectively reducing the bendable angle of the glass cover, and after bending, the circular polarizer and the glass cover are integrated. The body of the glass cover does not shift.

Description

technical field [0001] The invention belongs to the field of foldable display screens of mobile phones, and more specifically relates to a foldable ultra-thin glass protective cover with circular polarization function and a manufacturing method. Background technique [0002] Since the beginning of 2019, companies including Samsung and BOE have successively released fully self-developed foldable self-luminous OLED flexible screens. According to online news, Samsung, Huawei, Rouyu, Xiaomi and other companies have also made related folding mobile phone products. China Unicom even stated in the official Weibo that "folding screen mobile phones are not far away!" [0003] The flexible screen that is indispensable in folding screen mobile phones not only has super portability, but also has the advantages of high resolution, high brightness, and low energy consumption. In the future, mobile phones using this technology can not only provide high image quality, but also expand batte...
