The polarizer is one of the important materials of the liquid crystal display, and is a composite material prepared by a process of multiple-time compounding, stretching, coating, etc. of a polyvinyl alcohol (PVA) stretched film and a cellulose acetate film (TAC). Achieve high brightness and high contrast characteristics of liquid crystal display. The polarizer accounts for about 10% of the cost of the TFT-LCD (Thin Film Transistor Liquid Crystal Display) panel. Because its production technology brings together a variety of technologies such as polymer materials, microelectronics, optoelectronics, thin films, high purity and computer control, polarizers have a high technical content, and there are only a handful of companies that can produce polarizers in China. .

The earliest polarizer consists mainly of a PVA film that produces polarized light in the middle, and a TAC (transparent triacetate film) protective film on both sides. In order to facilitate the use and obtain different optical effects, the polarizer supplier should apply the pressure sensitive adhesive on both sides and then apply the release film on both sides. This polarizer is the most common TN we have. Fully transmitted polarizer. If you remove a layer of release film and then combine a layer of reflective film, it is the most common reflective polarizer.

The pressure sensitive adhesive used is a high temperature moisture-proof pressure sensitive adhesive, and the PVA is specially dipped (dye series). The polarizer is a wide temperature type polarizer; the pressure sensitive adhesive used is added to prevent it. The UV-passing component can be made into an ultraviolet-proof polarizer; the birefringent optical compensation film can be composited on the transmission original film to form a polarizer for STN; and the light-transition film can be combined on the transmission original film to make a film. A wide viewing angle polarizer or a narrow viewing angle polarizer; coloring the pressure sensitive adhesive, PVA film or TAC film used, that is, a color polarizer. In fact, with the development of new liquid crystal display products, the types of polarizers are becoming more and more widely used.

For our LCD industry, polarizers are mainly used for the replacement of color LCD screens, as small as mobile screens, up to sixty inches of LCD TVs. Screen scratches, aging of polarizing film, etc. can all be restored to new effects through certain technical means.
