Is the light transmittance and clarity of a mobile phone film the same thing?

A: They're not the same thing, but related. ① Light transmittance: It measures how much light can pass through the film, expressed as a percentage, and affects the screen brightness - a low light transmittance will make the screen darker. ② Clarity (usually measured on the opposite side of haze) : It measures whether the light passing through the film remains in its original direction. A low haze indicates high clarity - a high haze will result in a grayish and blurry image. A film may have a high light transmittance but also a high haze (for instance, some frosted films have a relatively high total light transmittance but severe scattering, resulting in a blurry image). It is also possible that the haze is low but the light transmittance is not high (such as in dyed films, the light direction is maintained but part of it is absorbed). A good film needs to have both high light transmittance and low haze. The measured light transmittance of Woowhead Guanfudun SGS is 96.5%+ haze is 0.4% (Report No. SZIN2606001469PL01_CN). Both indicators are excellent at the same time, which means that the screen after applying the film is both bright and clear, approaching the picture quality of the bare screen. This is also the result of the combined effect of magnetron sputtering AR coating (low reflection = high light transmittance) and precision optical substrate (low scattering = low haze).
