The term LED television should really be a loosely used term. This is because an LED television is actually just an LCD television, but instead of using fluorescent light to illuminate the screen, it uses LED light instead.
The price difference between LCD and LED can vary markedly, so why is this?
At the moment the difference in price between these two technologies can only be attributed to LED being the newer type of technology. It does not necessarily mean it is the best, although some experts would disagree.
What is the difference between edge lit LED and Full array LED?
Edge lit LED televisions are lit only at the edges of the set. This means that the screen can be a lot thinner than full array LED televisions. But they do not have the brightness adjustability of full array sets.
