The price of thin: Samsung reveals its edge-lit LED-based LCDs
CNET previews Samsung's new lineup of edge-lit LED-based LCD displays, which are finally starting to appear on store shelves.
Samsung announced its new lineup of "LED TVs" at CES in January, and gave CNET editors a walk-through today to preview the technology. The company also set prices, and as expected, it'll cost you a fortune to take one of these thin models home.

The slideshow above goes into the nitty-gritty behind, or along the edge of, the technology. The short story is that the LEDs themselves are arranged along all four edges of the screen, and a special "light guide" sends light toward the middle. The result, according to the company, is similar uniformity characteristics to standard backlit LCD displays.
Edge-lit LED-based displays are also 40 percent more energy-efficient than standard-certified LCD sets, and measure just 1.2 inches thick.
The downside is that they're extremely expensive. The cheapest model, the 32-inch
