LED Big Screen TV Information

With the rise of LED Big Screen TVs on the near horizon and quickly dropping, here’s a summary of CNET’s list to help you sift through LED fact and fiction.

1. LED TVs are not new: LED TVs are simply LCD TVs that are backlit with light-emitting diodes and have been on retail shelves since 2007.

2. There are two LED configurations: “full array” LEDs are backlit across the panel, like a standard LCD. “Edge-lit” LEDs are backlit on the sides of the panel, projecting light inward and reducing the thickness of the TV.

3. “Local dimming” may be offered on both configurations: this feature dims portions of the screen to reduce the amount of light that leaks through darkened pixels, which results in darker blacks. The deeper the black on your TV, the better your contrast ratio, which correlates with a better overall picture quality.

4. Edge-lit TVs are thin, but uniformity suffers: with edge-lit displays, white images may appear brighter or “hotter” on the edges of the screen. Contrastingly, dark images may appear lighter near the edges.

5. LEDs don’t improve LCD’s off-angle viewing: LCD TVs are notorious for their decreased picture quality from different, angled views. Unfortunately, neither LED configuration improves this weakness.

6. LEDs are more efficient: this is great news for those energy-conscious individuals LED TVs are the most power-efficient flat panels available.

7. LED technology will improve, somewhat: according to engineers, to truly perfect an LED TV, it would require 2.1 million LEDs to individually light 2.1 million pixels in a 1080 p TV. Not surprisingly, this simply isn’t cost effective for manufacturers. For mass-produced models, the limit of LED improvement will be found at the intersection of the number of LEDs vs. production costs.

8. LEDs are more expensive: I know, not what you wanted to hear. For instance, according to CNET, LG’s least-expensive 32-inch LED is still $1,100. However, with added competitors entering this market continuously, prices should drop substantially over the next year or two.

9. Top LED TVs rival the best plasmas, but still have shortcomings: at the highest tier, picture quality is almost synonymous, but off-angle viewing and picture uniformity still prevent LED TVs from surpassing plasma’s picture quality.

10. Without the correct picture settings, LED technology won’t matter: regardless of the price tag, if you don’t set-up your LED TV correctly, you won’t experience its true potential.
