Full Answer

An LED, or light-emitting diode, display refers to an LCD, or liquid-crystal display, that uses a number of light-emitting diodes to provide illumination for an LCD panel. Traditional LCDs use a small number of single-color lamps to provide lighting for the screen. Without a backlight, the image produced by an LCD is very dim and difficult to distinguish.

The LED technology is generally considered superior because it provides a greater degree of granularity of control of the backlight and the ability to dim the display locally by reducing the current sent to individual LEDs.

The two types of LED displays are edge-lit and back-lit LED's. The LEDs of edge-lit displays are arrayed around the perimeter of the display and so have a reduced ability to affect local brightness of the display. Backlit LED displays have an array of LEDs that covers the entire area of the LCD, allowing for very fine control of illumination over a small area of the LCD panel. Regardless of the backlight type, LED-lit displays are considered to be superior to traditional LCDs.
