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 ultrathin glass protective cover plate with a circular polarization function. The foldable ultrathin glass protective cover comprises ultrathin glass; an ink frame an ink frame is printed under the ultrathin glass; the lower part of the ink frame is coated with an explosion-proof layer; a nanoscale wire grid polarizer (WGP) is printed under the explosion-proof layer; and the lower part of the nanoscale WGP is coated with a 1 / 4 lambda phase difference film. The circular polarizer provide by the invention does not need bonding by an optical adhesive, functionsof a circular polarizer is combined, and the thickness and the bonding process of an optical adhesive and a conventional circular polarizer substrate are omitted, so that functions of the circular polarizer and a glass cover plate are integrated into a whole, the bendable angle of the glass cover plate is effectively reduced, and deviation of the circular polarizer and the body of the glass coverplate after bending is avoided.

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...
