BACKLIGHT

Backlight

A backlight is a form of illumination used in liquid crystal displays . As LCDs do not produce light themselves, they need illumination 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 in 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 by Peter J. Wild IEEE First-Hand History under its section Backlit LCDs.
