An LED TV uses less power, provides a brighter display with better contrast, a thinner panel, and lesser heat dissipation than a conventional LCD TV. This is because an LED TV uses light-emitting diodes for backlighting as opposed to the CCFLs of conventional LCD TVs. The display of an LED TV is not an LED display, so a more technically correct name for it would be "LED-backlit LCD television."

Picture Quality

Even though some say the picture quality of an LED TV is better, there is no straight answer for which has better picture quality since both TVs use the same kind of screen. For instance, a higher-end LCD TV can have a better quality than a low-end LED TV, but if you look at high-end models of either TV, the picture quality will be comparable.

Color

An LED TV offers more colors, especially ones that use RGB-LED backlighting.

Dynamic contrast

RGB Dynamic LEDs show truer blacks and whites and thus get higher dynamic contrast ratio (which is desirable in a TV), at the cost of less detail in small bright objects on a dark background (such as star fields)

Slim frame

Edge-LED backlighting technique allows an LCD TV to be extremely thin. LED televisions that are only 1 inch thick are also available.

Power Consumption

LED TVs use energy-efficient light emitting diodes (LED) for backlighting. These consume less power than cold cathode fluorescent lamps (CCFL) used in traditional LCD televisions. Power savings are typically 20-30%.

Price

On average, LED TVs are priced higher than traditional LCD TVs that use CCFLs for backlighting.

The Amazon's Best Sellers' list for LCD TVs has a wide range of TVs ranging starting from $100 all the way up to a few thousand.

LED TVs are the most popular and also come in a wide range of prices from $120 and up, as seen on the Amazon's Best Sellers' list for LED TVs.
