Backlight
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.
 Backlights illuminate the LCD from the side or back of the display panel, unlike frontlights, which are placed in front of the LCD.
 Backlights are used in small displays to increase readability in low light conditions such as in wristwatches, and are used in smart phones, computer displays and LCD televisions to produce light in a manner similar to a CRT display.
 A review of some early backlighting schemes for LCDs is given in a report "Engineering and Technology History" by Peter J. Wild.
