Foldable ultra-thin glass protective cover plate with touch screen function and manufacturing method thereof

Abstract

The invention discloses a foldable ultra-thin glass protective cover plate with a touch screen function, the foldable ultra-thin glass protective cover plate comprises ultra-thin glass, wherein an inkframe is printed below the ultra-thin glass; an explosion-proof layer is coated below the ink frame; and a touch circuit layer is printed below the explosion-proof layer. The foldable ultra-thin glass protective cover plate has a small thickness, is coated with a functional layer in a printing and coating mode, omits optical glue, not only integrates the functions of a touch screen, but also saves the thickness and bonding process of the optical glue and a PET film, so that the functions of the touch screen and the glass cover plate are integrated, and the glass cover plate with the touch screen function is easier to fold and has no crease.

Description

technical field [0001] The invention belongs to the field of folding display screens of mobile phones, and more specifically relates to a foldable ultra-thin glass protective cover plate with a touch screen 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 battery...

Problems solved by technology

Chinese patent 201920901725.6 involves a foldable glass cover, but does not involve the function of the touch screen. The current traditional touch screen method is to first make the touch circuit on the PET film, and then use optical glue to attach it to the glass cover or OLED panel. In general, if you encounter a folding OLED panel, this method directly increases the thickness of the entire folding display, which is not conducive to screen folding, especially the inward-folding screen like the Samsung Galaxy Fold phone (the outer-folding screen phone is like Huawei Mate X, the screen On the outside, the folding angle of the mobile phone is relatively large compared with the internal folding), and the requirements for screen folding are particularly high. If the traditional touch screen method increases the thickness, it is not easy to fold, and the touch screen is prone to deviation from the glass cover or OLED panel.
