Background
The commonly used liquid crystal display polaroid is usually compensated by an inner protective film layer on one side of a pressure-sensitive adhesive, so that the display effect is better; the other inner protective film is an uncompensated film. However, UV absorption affects the light stability and lifetime of the liquid crystal display, and thus an optical inner protective film (e.g., a cellulose triacetate film) needs to be added with a UV absorber in addition to the "zero" compensation film of the IPS mode, so that the polarizer has a certain UV resistance. The UV protection measure can greatly reduce the transmittance and the polarization degree of the purple light wave band of the polaroid.
