What is LED-LCD tv?

Answer 1

LCD displays use tiny liquid crystal shutters, one for each pixel that makes up the display. Behind the shutters is a light source that passes through the shutter when it is open. LCD displays have used a form of fluorescent lighting behind the shutters but increasingly, LEDs are being used as the light source. The display technology hasn't changed, just the light source.

Note that these are different to true LED displays. These use LEDs to create the image directly and replace the liquid crystal shutters and the light source behind them. Although they are a very recent introduction in domestic televisions, this technology has been around in the large arena and stadium displays for many years.

Answer 2

A LED tv is a LCD tv with LED backlighting.

non led lcds have CFL backlighting or such (compact fluorescent

LED tv's are different because they can be thinner and have a more dynamic brightness range (in general).

The LCD means liquid crystal display and is just a type of display (opposite of plasma or such).

LED LCDs are light emitting diode backlit liquid crystal displays. (the best out now)

so the best TVs are currently 3d led lcds.
