Disadvantages of ag frosting process

The disadvantage of AG frosted process is expensive.

AG glass (Anti-Glare Glass) is a glass surface that is treated on one or both sides to achieve the effect of multi-angle diffuse reflection, thus improving the viewing angle of the screen and reducing the reflections on the glass surface.The parameters of AG glass are gloss, haze, roughness, and transmittance.

There are various processes to realize AG frosted glass, and the traditional process to realize the function of AG frosted is acid etching, which is equivalent to the first generation. AG glass process should be used in the earliest glass wine bottles, which have better light transmittance and lower haze. Recently, in the cell phone industry, the most typical example is the iPhone 11 series, and the OnePlus 6 uses the chemical etching process to realize AG frosted glass. Although the Yiga 6 appeared before the iPhone 11, but Yiga is not before Apple to use AG frosted glass, Apple has long been in another product to realize the accumulation of technology.
