HIGH-DEFINITION FLICKER-FREE ETCHED GLASS, MANUFACTURING PROCESS THEREFOR, AND APPLICATION THEREOF

A high-definition flicker-free etched glass, having a glossiness of 110-145, a haze of 3-10, and a definition of 90%-99.5%. The front surface of the glass is an irregular concave-convex lens surface having an average roughness of 0.025 µm-0.050 µm and provided with dents and bumps; the average chord length of the dents is 1.8 µm-10.0 µm; the average depth from the bottom of the dent to the top of the bump is 0.2 µm-0.7 µm; the average chord length of the bumps is 0.1 µm-0.5 µm; when a 250 µm*250 µm area on the front surface of the glass is observed after being amplified 500 times, there are 800-2500 irregular bumps, and the irregular bumps form an array of micro-convex lenses. By means of a sandblasting etching process, the spherical radius of each bump on the front surface of the etched glass is reduced and the focal length of each micro-convex lens is shortened, so that the focal point of light is closer to the surface of the glass, brightness of a high-pixel display device is brighter and more uniform, and it is not prone to see flicker of the focus point by the naked eye any more.
