Mainly composed of light source, light guide plate, optical diaphragm, plastic frame, etc. The backlight has the characteristics of high brightness, long life and uniform light emission. At present, there are mainly three types of backlight sources: EL, CCFL and LED. According to the different light source distribution positions, they are divided into side-light type and direct-light type (backlight type). As LCD modules continue to develop in the direction of being brighter, lighter, and thinner, edge-lit CCFL backlights have become the mainstream of backlight development.
