and which one is better?

led tv contains both led and lcd. led is used for background lighting so the black is darker than lcd's black. led tvs have a thinner backing and uses less power. led also has a brighter display and better contrast ratio so led images are sharper than lcd images.

led tv is better but the increase in price might not be worth it. it's usually several hundred dollars more than an lcd tv of the same size.

they are nearly the same. both have a liquid crystal display screen. the only major difference between the two is that older or less expensive sets use a fluorescent lamp for the backlight, while an ''''''led'''''' set uses a bank of light emitting diodes.

the led backlighting uses less electrical power than the fluorescent lamp. there are two versions, ''''''edge'''''' lighting and ''''''full matrix.'''''' edge-lit sets can be very thin. full matrix sets allow for ''''''local dimming,'''''' which can bring improved contrast in specific areas of the screen.

new for 2011: some of the latest model edge-lit sets also provide for a certain degree of local dimming.

however, don't look for a *major* difference in picture quality. the hd picture on an ''''''led'''''' set will be difficult to distinguish from a very good conventional lcd set.
