LED TVs are high definition televisions that use LEDs as the backlight of LCD panel. They're technically called as LED-backlit LCD TVs. LEDs are light emitting diodes that are electronic semiconductors plus they respond quickly if they are switched on and off. Household current is needed for the LED to radiate light. This is why why LED s give higher contrast than other hi-def televisions because the LEDs can be switched on and off independently giving an in-depth black and high brightness concurrently. This is called the local dimming that other televisions don't have. Before, local dimming is just 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 if the television is backlit or edge-lit, high contrast ratio is assured.

The LEDs may also be smaller than the fluorescent panels utilized in LCD TVs so they tend to be more power efficient. They are also lighter than the previous panels making the televisions slimmer and lighter than other high definition televisions. This makes this high definition TV easier to hang on walls plus more stylish when it comes to the outside.
