How LED TV Works
LED (Light Emitting Diode) televisions are in fact LCD TVs that are backlit by LED lights instead of the traditional cold cathode fluorescent lamps (CCFC). LEDs are comprised of small semiconductors that glow while exposed to electric current.
Due to the use of LEDs as opposed to CCFCs, LED TVs offer more energy efficiency, brighter display panels and slimmer designs. Depending upon the configuration of backlights, LED TVs can either be Full LED TV or Edge LED TV. As suggested by their name, in full LED TVs LED lights are arranged behind the whole LCD panel whereas in edge LED TVs, only along the edges. Some LEDs employ local dimming that can dim or lighten individual or group of LEDs for enhanced quality and uniform output.
