backlight


A backlight is a form of illumination used in liquid crystal displays(LCDs).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, and in computer displays and LCD televisions to produce light in a manner similar to a CRT display.

Light Emitting Diode



Light Emitting Diode, or LED, backlight is the most popular backlighting for small and medium LCDs.The advantages of LED backlighting are its low cost, long life,immunity to vibration,low operational voltage, and precise control over its intensity. The main drawback is it does require more power that most of the other methods, and this is a major drawback if the LCD size is large enough.
