LED Tv’s is a term used by Samsung. This tv is like any other LCD but with LED’s used as a back-light. This means it is possible to get greater contrast and darker blacks. They also use less power.

    LED tv are LCD tvs with light emitting diodes as back lights most lcd tvs use Miniature cold cathode tubes.
    I have seen both types of tv on display and the picture quality is virtually indistinguishable.
    The only advantages of led would appear to be a slimmer tv and possible longer lifespan.
    The disadvantage of led at present is price which is forecast to drop near to the price of conventional lcd tvs.
    Some manufactures are developing led tvs in which the back light levels in different areas of the screen can be varied to increase the apparent contrast.

    LED TV’s are still really LCD TV’s, but they use Light-Emitting Diodes as a light source behind the LCD panel rather than fluorescent tubes. LED-backlighting is a newer technology that should allow future TV’s to look better, although neither one is inherently better as things sit today.

    With traditional LCD TV’s, the fluorescent lights are always “on” behind the LCD layer. The liquid crystal is there to block the light or let it through depending on the image you’re watching. But you generally get some light “leaking” between the pixels which is why you can’t ever get the picture to look really black as long as the TV is turned on.

    Since LED’s are individually addressable, the idea is that you could turn parts of the backlight on or off to make parts of the screen blacker during dark scenes. Pretty cool. The implementation of these new features is only really starting to heat up so it’ll be interesting to see how it progresses. For now, the advantage of CCFL-backlight is that it is a mature technology and predictable. The advantage of LED-backlight is that you can get a TV that is even thinner and may consume even less power.

    Buy the TV that looks best to you.
