Optical performance evaluation technology of protective film

Polarizing films are usually used for the front and back layers of the LCD. Place one of the polarizing films in parallel on top of the other, and the brightness of the LCD screen will be the brightest; if one of the polarizing films is placed vertically on top of the other, the LCD screen will appear almost black. Therefore, it can be judged that the optical characteristics of LCD, such as brightness and contrast, are largely affected by the characteristics of the polarizing film.
