Abstract

The invention relates to the technical field of mobile phone ultrathin glass. The technical scheme of the invention is a structure for improving bendability of an ultrathin glass mobile phone cover plate. The structure is prepared by a manufacturing method for improving bendability of an ultrathin glass mobile phone cover plate. The structure for improving bendability of an ultrathin glass mobilephone cover plate comprises an ultrathin glass mobile phone cover plate, concave areas are arranged on the upper surface and / or the lower surface of a bending shaft of the ultrathin glass mobile phonecover plate, and the concave area is an arc-shaped groove. According to the manufacturing method, only the glass near a bending shaft is thinned, the use amount of a hydrofluoric acid thinning agent / flatting agent is saved, and the material cost and the environment-friendly treatment cost are saved, and as a thicker ultrathin glass is used, the strength is better, and the yield in the productionand manufacturing process of the mobile phone cover plate is high.

Description

Technical field [0001] The present invention relates to the technical field of ultra-thin glass for mobile phones, and in particular to a manufacturing method and structure for improving the bendability of ultra-thin glass mobile phone covers. Background technique [0002] Samsung, Huawei, Motorola, and Xiaomi have all begun to launch folding screen mobile phones. In order to solve the crease problem of the plastic cover and strengthen the protection of the AMOLED panel underneath, Samsung Electronics has introduced foldable ultra-thin glass (UTG) as a protective cover for folding screen mobile phones and will support the S Pen function. The industry predicts that the market for foldable mobile phones will exceed 10 million units in 2020, and may grow to 70 million units in 2022. UTG ultra-thin glass protective covers will be in short supply! [0003] But UTG is glass after all and has a very high risk of bursting. The UTG structure (patent number: 201910457952.9, 20202039...
