Across the past six years though, it has been developed to meet general lighting application demands. Samsung is among the first to incorporate light-emitting diodes (LED) into television technology, it is called the LED TV which is now accepting the technological world by storm. Samsung uses a term LED TV (light emitting diode television) for depicting LCD (liquid crystal display) TVs which utilizes LED Backlighting.

LED TV is a arguable term effectively used for the advertisements between Samsung and its challengers. But the complaint of the competitors is, LED TV produces a display of 100% LEDs and which is not compromised in this. LEDs in their current form are much too large to be individual pixels on a conventional television. In order to capture some of the hype around O-LED TVs, Samsung has chosen to brand their LED-lit range of LCD TVs but still except for the Sony XEL-1 they are not commercially available. LED-backlit LCD TVs do differ from conventional LCD TVs in some crucial areas: 1. LED televisions can produce bright image and deep blacks (doesn’t work for Edge-LED). 2. They can be extremely slim with Edge-LED lighting. 3. LED TV offers lower power consumption. 4. Especially when RGB-LED backlighting is used, LED TV also offers a wider colour gamut.
