LED TV - What is a LED TV?

What is a LED TV?
A led TV is an LCD TV that uses LEDs to illuminate the display. There are two ways to do this: either by placing LEDs across the complete back of the display, or by placing LEDs just approximately the edge, which is called an "edge lit" display. Both presentation use less power than plasma TVs and LCD TVs lit with fluorescent tubes.

History of LED TV
LED technology was first used as status and indicator lamps. Over 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 taking the technological world by tempest.

Samsung uses a term LED TV [http://www.careoffice.co.in/home-entertainment/led] (light emitting diode television) for recounting LCD (liquid crystal display) TVs which utilizes LED Backlighting. LED TV is a divisive term efficiently used for the advertisements between Samsung and its competitors. But the complaint of the competitors is, LED TV produces a display of 100% LEDs and which is not concession in this. LEDs in their current form are much too large to be individual pixels on a conventional television.

In order to imprison 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.

1. LED televisions can produce bright image and deep blacks (doesn't work for Edge-LED).
2. They can be tremendously slim with Edge-LED lighting.
3. LED TV offers lower power utilization.
