What is the difference between LCD and LED-LCD tv?

Question by Russell S: What is the difference between LCD and LED-LCD tv?
I’m loking into picking up an HD TV and was wondering what the difference between LCD and LED-LCD are, mainly in terms of quality. Is the difference really that noticeable? Obviously LED-LCD seems more expensive, and I’m not planning on spending more than ,000.

LCD uses a back light tube to illuminate the screen. LED uses many little lights that use less power and are healthier for your eyes. They also make a crisper picture because the light is more even and can be made much much thinner then LCDs. They are expensive because they are new, but will probably drop and be the cheapest monitors yet in 5 years.

  2. 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.

    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.
