What is LCD? A liquid crystal display, typically referred to as an LCD, is a flat display technology that uses electrodes and polarizing filters to selectively enable or disable pixels of light to pass from a backlight or reflective backing to the eyes of the viewer.
Animation of an LCD, both unlit and with electroluminescent backlight switched on. A backlight is a form of illumination used in liquid crystal displays (LCDs). As LCDs do not produce light by themselves (unlike for example Cathode ray tube (CRT) displays), they need illumination (ambient light or a special light source) to produce a visible image.
