Title:
FOLDABLE ULTRA-THIN GLASS COVER PLATE HAVING CIRCULAR POLARIZATION AND TOUCH SCREEN FUNCTIONS AND FABRICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/017076
Kind Code:
A1
Abstract:
A foldable ultra-thin glass cover plate that has circular polarization and touch screen functions and a fabrication method. The foldable ultra-thin glass cover plate that has circular polarization and touch screen functions comprises ultra-thin glass (2); an ink border (3) is printed below the ultra-thin glass (2); an explosion-proof layer (4.1) is coated below the ink border (3); a nano-level WGP polarizer (4.2) is printed below the explosion-proof layer (4.1); a 1/4λ phase difference film (5) is coated below the nano-level WGP polarizer (4.2); and a touch circuit layer (10) is printed below the 1/4λ phase difference film (5). Functional layers are covered by means of printing and coating, which not only combines the functions of touch screen and circular polarization, but also omits the thickness and bonding processes of optical glue, PET films, and traditional circular polarizer substrates. As a result, the functions of circular polarization and touch screen are integrated with the glass cover plate, so that the glass cover plate that has the circular polarization and touch screen functions is easier to fold without creases.
