LCD television uses liquid crystals that turn on and off to build an image across the screen. The crystals don't emit any light themselves so they need a light source behind the LCD panel. The light source has been fluorescent until recently, but newer models are introducing LED lighting as an alternative to fluorescent.
A true LED television uses the LEDs to generate the picture directly. For each pixel, a red, a green and a blue LED are needed. Unlike an LCD television, each LED generates its own illumination so there is no additional light source needed.
True LED televisions are making an entry into the home market, but the technology has been around for many years. The large arena screens that are seen in concerts and sporting venues are also LED displays. Although rather too large to fit in most homes, they operate on the same principles as the new domestic LED televisions.
