Liquid crystal displays are mainly composed of the following parts:
Substrate: A thin and uniform substrate usually made of glass, which is used to support other components and ensure the flatness and transparency of the display.
Liquid crystal layer: Located between two glass substrates, it is the core component of LCD. The arrangement of liquid crystal molecules is controlled by electric fields to achieve pixel brightness and color adjustment.
Color filter: Located above the liquid crystal layer, it is usually composed of red, green and blue filters. These filters determine the color of each pixel.
Alignment film: A thin film coated on the inside of the substrate, which is used to control the rotation effect of the liquid crystal material, thereby affecting the display quality of the LCD.
Polarizer: Used to polarize the light passing through the polarizing film, which is a key part of LCD display technology.
Drive circuit: Including drive board and power board, etc., responsible for controlling the voltage, phase and other parameters applied to the pixel electrode to realize the display of the image.
Backlight unit: Located on the back of the LCD screen, it provides light source so that the LCD screen can display images.
