Backlight (BL)
In a general CRT screen, a high-speed electron gun is used to emit electrons and hit the phosphor on the silver light screen to generate bright light to display the picture. However, the LCD monitor itself can only control the brightness of the light passing through. The function of luminescence. Therefore, a backlit panel must be added to the LCD to provide a high-brightness light source with uniform brightness distribution. We can see in the above TFT LCD cross-sectional structure diagram that the main parts of the backlight panel There are lamps (cold cathode tubes), reflectors, light guide plates, prism sheets, diffusion plates, etc. Lamps are the main light-emitting parts, and the light guide plate distributes the light everywhere. The reflection plate restricts the light The residence is only moving in the direction of TFT LCD. Finally, with the help of prism sheet and diffuser, the light is evenly distributed to each area to provide a bright light source for TFT LCD. TFT LCD controls the liquid crystal by voltage Rotate to control the brightness of the passing light, thereby forming different gray levels.
