Backlight is a kind of light source behind LCD TVs, and its lighting effect will directly affect the visual effect of LCD TVs. The LCD itself does not illuminate, it shows that the image is the result of its modulation of the light.
The liquid crystal display uses the technical principle of passive illumination, so the liquid crystal needs a backlight system to provide a light source. At present, the backlights used in LCD TVs are mainly classified into CCFL (Cold Cathode Fluorescence), LED (Light Emitting Diode) and HCFL (Hot Cathode Fluorescence). Among them, CCFL is the most widely used, HCFL has just started, and the technology is not mature enough.
