Abstract

The invention discloses an ultrathin glass layer and a preparation method thereof and a cover plate. The preparation method of the ultrathin glass layer comprises the following steps: spraying a frosting liquid on the surface of at least one side of an ultrathin glass layer to form a surface concave-convex structure; cleaning the surface of the ultrathin glass layer by using hydrofluoric acid; and carrying out chemical polishing treatment on the surface of the ultrathin glass layer. Compared with an existing ultrathin glass layer and a preparation method thereof and a cover plate, the ultrathin glass layer has the advantages that the surface concave-convex structure is arranged on the surface of at least one side of the ultra-thin glass layer, so that the contact area between the ultra-thin glass layer and an adjacent film layer is increased, the bending performance of the cover plate is improved, and layering of the inner film layer of the cover plate is avoided; and the concave-convex structure is favorable for reducing ambient light interference, increasing diffuse reflection and improving the outdoor display performance of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an ultra-thin glass layer, a preparation method thereof, and a cover plate. Background technique [0002] With the development of science and technology, flexible display devices show more and more extensive application prospects. The main advantage lies in its foldability, which can realize product diversification and achieve excellent display and appearance effects. At present, all mobile phone terminal and display manufacturers are actively deploying and conducting technology development. [0003] For bendable display devices, the original glass cover cannot be used, and what material to use to protect the display screen on the surface is an extremely important issue. It needs to have the following main features: high surface hardness, not easy to scratch, easy to bend, good recoverability, high light transmittance, and high flatness. [0004] The development of materials ...
