What is LED TV?

The first thing to know about LED (Light Emitting Diode) TVs is that they are simply LCD TVs with a different kind of backlighting. The screen remains the same but LEDs are used in place of Cold Cathode Fluorescent Lamps that are found in most LCD TVs. The LEDs can come in two forms, white or RGB 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.

Currently LEDs are not small enough to be used for individual pixels in domestic televisions, and so the use of true LED TVs is restricted to much larger screens in places such as sport stadia.
Don't let this put you off however, as there are some great benefits to choosing an LED TV over a standard LCD TV.

• Improved brightness and contrast levels, with deeper blacks.
  
• The use of Edge-LED lighting allows the TV to be thinner than standard LCD TVs.
  
• LED TVs can consume up to 40% less power than a LCD TV of similar size
  
• They can offer a wider colour gamut, especially when RGB-LED backlighting is used.
  LED TVs are also more environmentally friendly due to there being no mercury used during manufacture.

Overall there are many benefits to buying a LED TV rather than a standard LCD TV. A comparison between LED and LCD can be found here on the LED vs LCD page.
Some of the biggest electrical companies such as Samsung, Sony and Sharp all offer a range of fantastic LED TVs.
