Backlight Module, the light source of TFT-LCD, is constructed by optical films, light guide plate, LED light bar, back-cover and plastic case. Because the liquid crystal molecule only function as the penetration level that doesn't illuminate spontaneously, it is necessary to add a backlight module. Without a backlight source, the liquid crystal display module would only present a pitch-black screen, and no matter how the internal liquid crystal molecules rotate, nothing would be visible from the outside. Backlight sources can be classified into two types according to their light emission:. A backlight module is a core component of an LCD, providing stable, high-brightness light for clear image display. It's the system that turns invisible light into the vivid images you see. As an LCD display manufacturer, CNK Electronics Co.
