what is polarizer film for lcd?
LCD polarizer is a filter that controls light waves. It is designed to block light waves of specific polarization, while allowing light waves of different polarization to pass through. The LCD has a lighting system that illuminates its pixels. Some use light emitting diodes (LED), while others use electroluminescence (EL). A polarizer is a filter material placed between the backlight and the LCD pixel layer.
Liquid crystal display (LCD) is composed of electronic display devices with liquid pixels (TV, computer display, smartphone screen, etc.). LCD contains many components, among which polarizer is one of the most critical components.

Working principle of LCD polarizer
The polarizer operates by limiting the type of light that reaches the LCD pixel layer. The purpose of the polarizer is to create a visible image. Without them, we would not be able to see the image generated by the LCD.
LCD usually has two polarizers. Polarizers are usually made of transparent crystalline materials. They are designed to allow light of certain wavelengths to pass through while blocking light of other wavelengths. The light generated by the LCD lighting system must pass through the polarizer to reach the pixel layer.

Polarizer works by polarization. Pixels in the LCD must project a specific level of brightness to create a visible image. The problem is that most LCDs consist of millions of pixels. To create an image, many of the pixels require different levels of brightness. For example, some pixels of an LCD may need to be brighter than others. Using polarizers, LCDs can control the brightness of their pixels to produce high-quality and visible images
