There are polarizers on the bottom and the surface of the LCD screen. The optical properties of the polarizers include three main performance indexes: degree of polarization, transmittance and hue, other parameters include UV protection and the transmittance, total reflectivity and diffuse reflectivity of the semi-permeable polarizer.

In the use of ordinary LCD products, the higher the performance index of polarizability and transmissivity, the better. The higher the degree of polarization and transmittance, the higher the display efficiency and the lower the relative energy consumption of the LCD display. However, for the polarizer products dyed with conventional iodine, the degree of polarization and transmittance are a pair of contradictions. The higher the degree of polarization, the lower the transmittance, and it is also restricted by the Hue, therefore, the polarizing power of the general type POLARIZER is between 90% (99%) and 41% (44%) .
