There’s so much marketing hype regarding flat-panel LED TVs, I thought I’d jot a quick post to demystify things.

LED TV picture quality has come a long way in the last couple of years — nearly equaling the best plasma TVs (which are still the top dog when it comes to the best picture).

An LED TV is simply an LCD TV that’s “backlit” with lots and lots of LEDs.  Prior to the LED-backlit technique, LCD TVs were backlit with fluorescent lights (the same basic tube-light technology as you may have in your office).

When comparing LED TVs, here’s the most important thing you need to know:  Select a model that’s backlit by a “full array” of LEDs — that is, LEDs that span the entire back of the picture.  Avoid “edgelit” LED TV sets which only use LEDs along the exterior edges of the picture and project the light inward.

The biggest benefit of “full array” backlighting is deeper blacks, creating a more vivid picture.

If you can, compare LED models side by side at a retail outlet.  With your new knowledge, you’ll be able to spot full-array backlit LED models in a blink — and have a decided advantage when selecting the units that deliver the best picture.
