What is the light transmittance of Guanfudun?

A: The mass production standard for the light transmittance of Guanfudun is ≥ 96%. The typical value measured by SGS third-party testing is 96.5%, with the report number SZIN2606001469PL01_CN. It can be verified through the official SGS channels. For comparison, the light transmittance of ordinary tempered films in the market is approximately 90% (based on public information). High light transmittance means that the screen brightness loss is extremely small after applying the film, and the picture transparency is close to that of a bare screen.
