LED TVs are hi-def televisions that use LEDs since the backlight of LCD panel. They are technically called as LED-backlit High definition tvs. LEDs are light emitting diodes that are electronic semiconductors plus they respond quickly when they're switched on and off. Electric current is needed for the LED to radiate light. Because of this , why LED s give higher contrast than other hd televisions because the LEDs could be switched on and off independently giving a deep black and high brightness simultaneously. This is called the local dimming that other televisions don't have. Before, local dimming is merely available in backlit LED TVs wherein the LEDs they fit at the back of the panel. However, if 2010 came, edge-lit televisions is now able to do local dimming too. So whether or not the television is backlit or edge-lit, high contrast ratio is assured.

The LEDs are also smaller than the fluorescent panels found in LCD TVs so they tend to be more power efficient. They're also lighter than the previous panels making the televisions slimmer and lighter than other hd televisions. This makes this higher definition tv easier to hang on walls and more stylish when it comes to the exterior.
