LED-backlit LCD television or LED TV (term used by Samsung Electronics, Toshiba, Philips, and LG Electronics) is an LCD TV that uses LED backlighting.[1] LED's are used for backlighting, instead of fluorescent lights. Light-emitting diode televisions (LED TVs) are LCD television sets that use LED as back light unit (BLU). LEDs in their current form are much too large to be individual pixels on a conventional television. The use of a true LED display is therefore reserved for much larger screens in sports grounds and other commercial locations.
The LEDs can come in two forms, Dynamic RGB LEDs which are positioned behind the panel, or white Edge-LEDs positioned around the rim of the screen which use a special diffusion panel to spread the light evenly behind the screen. [2]
RGB Dynamic LEDs This method of backlighting allows dimming to occur locally creating specific areas of darkness on the screen. This means you see truer blacks and much higher dynamic contrast ratios.
Edge-LEDs This method of backlighting allows for LED TVs to become extremely thin. The light is diffused across the screen by a special panel which produces a superb uniform colour range across the screen
