led tv local dimming image

I think the LED one's are better quality. Is that true? also, what makes them different?
Answer
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 a very good conventional LCD set will be difficult to discern from an "LED" set.

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