Écran backlight
A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light themselves - unlike for example Cathode ray tube (CRT) displays - they need illumination (ambient light or a special light source) to produce a visible image. Backlights are used in small displays to increase readability in low light conditions such as in watches, and in computer displays and LCD televisions to produce light in a manner similar to a CRT display.
