The LCD polarizer is attached to the back of the LCD screen, and there are polarizers on the bottom and the surface of the LCD screen. The optical properties of the polarizer include three main performance indicators: polarization, transmittance and color tone. Others also include anti-ultraviolet performance and half Transmittance, total reflectance and diffuse reflectance index of transmissive polarizer semi-transparent film.
In the use of general LCD products, the higher the polarization and transmittance performance indicators, the better. The higher the degree of polarization and transmittance, the higher the display efficiency of the LCD display device and the lower the relative energy consumption. However, for conventional iodine-dyed polarizer products, the degree of polarization and transmittance are contradictory. The higher the degree of polarization, the lower the transmittance, and it is also constrained by the hue. The polarization degree of the film products is between 90% and 99%, and the transmittance is between 41% and 44%.
