NSC Corporation announced in April 2020 that it has developed a liquid crystal panel made of a flexible glass substrate using chemical processing technology. The minimum radius of curvature supported by this panel is R100mm, which can be applied to places where curved surfaces are needed, such as car displays.
The total thickness of the liquid crystal panel is reduced to 0.15mm by chemical grinding
The new technology developed by NSC is as follows: Usually, a glass with a thickness of 0.5mm is used to make a liquid crystal panel with a thickness of 1.0mm, and the total thickness is reduced to 0.15mm by chemical grinding. In addition, using the chemical division method to divide the panel, it can be freely bent within the minimum radius of curvature R100mm.
Because this technology uses thick glass, it is less likely to be damaged during processing than thin glass. In addition, mass production of bendable panels is realized only by adding grinding and dividing processes, so additional equipment investment is also small.
Compared with physical processing technology, this technology is not easy to cause fine scratches, and can maintain the original strength of the glass. In the future, NSC will continue to further promote research and development, and plans to start mass production in 2022.
