Polarized layer: it is made of PVA (polyvinyl alcohol) film after dyeing and stretching. This layer is the main part of polarizer, also known as polarizer original film. The polarized layer determines the polarized performance and transmittance of the polarizer, and it is also the main part that affects the tone and optical durability of the polarizer.

Adhesive: it can be divided into reflective film side adhesive and stripping Film side adhesive. The function of the side adhesive of the reflective film is to firmly adhere the reflective film to the TAC film, and its technological requirements do not allow re-stripping. The adhesive on the side of the stripping film is a layer of pressure sensitive adhesive, which determines the Adhesive pefomens bilong polarisa na prosesing pefomens bilong patch{{3} Pefomens bilong em em i wanpela bilong ol hevi i gat bikpela wari long ol LCD polarisa yusa{{4} Seperet film: em i wanpela PET (etilen terefthalate) film i bin kotim wantaim silikon long wanpela sait, we i save mekim bikpela wok long lukautim presa sensitiv adisi long wanpela sait, we i save pilai wanpela rol long wankain taim, long wankain taim i save pilai wanpela rol long wankain taim, long wankain taim i save mekim wankain wok long wankain taim, long wankain taim i save mekim wankain wok long wankain taim, long wankain taim i save mekim wankain wok long wankain taim, long wankain taim i save mekim wankain taim, long wankain taim i save mekim wankain taim, long wankain taim i save mekim wankain wok long wankain taim, long wankain taim i save mekim wankain wok long peeling long wankain taim, we em i bin mekim bikpela wok long wankain taim, long wankain taim i save mekim wankain wok long peeling long wankain taim, we em i bin mekim bikpela wok long wankain taim, long wankain taim i save mekim wankain wok long peeling long wankain taim, we em i bin mekim bikpela wok long wankain taim, long wankain taim, em i bin mekim wankain wok long dispela taim. wok bilong LCD patch.

{{0}} Transmittance the Transmittance index of polarizer can be divided into three parts: single, Parallel and Crossed. Generally, integral sphere spectrophotometer is used to measure it according to JIS-Z-8701.

3. (Hue) Hue is represented by a and B values, which are usually measured by integrating sphere spectrophotometer. The values of a and B are the color coordinate values in the Lab color system of CIE (international lighting Commission). The approximate colors corresponding to a and B values can be found from the color coordinate diagram.

For LCD manufacturers, polarizer is very important for the stripping performance of glass substrate. Such as short time after pasting (4 ~ 6 hours) if it is difficult to peel off or there is residual glue on the glass plate after peeling off, the reworking property of the polarizer will be poor, and the bad patch will cause the whole LCD screen to be scrapped. However, if the peeling force is very small, it is easy to cause the loss of durability and moisture resistance of the pressure sensitive adhesive after the polarizer is attached to the glass substrate, as well as the sunken surface of the peeling film, which will affect the performance of the polarizer. 6. Durability test of the polarizer is to peel off the stripping film and the protective film of the polarizer and then attach it to the glass substrate. After pressure defoaming, put it into a constant temperature and humidity box to observe the changes before and after the experiment. The foaming stripping index is mainly to assess the durability of adhesive, and the optical change index is to assess the durability of PVA layer.
