Today, LCD liquid crystal displays have infiltrated various electronic terminals that require image and data display. Among the numerous flat panel display technologies, TFT-LCD occupies the absolute mainstream. What is the basic structure of a monochrome LCD screen.
1. Backlight board: The imaging principle of LCD is to control the brightness and darkness by blocking the light component of the liquid crystal. Therefore, a light source is necessary to see the image on the screen. Therefore, the backlight board is responsible for providing the most basic light source for the display of the LCD screen.
2. Lower polarizing plate: The lower polarizing plate is responsible for the work of regulating the direction of light to the same before sending it to the liquid crystal layer.
3. Film substrate: The twist angle of liquid crystal molecules is controlled by TFT.
4. Liquid crystal: This layer of liquid crystal molecules are twisted under the control of TFT to control the brightness of the light in the same direction, so that the brightness of the light to the rear pixel unit is changed.
5. Color filter: The inventor of this thing is estimated to be inspired by liquid crystal displays.
