PHILADELPHIA (CBS) - The Consumer Electronics Show is wrapping up out in Las Vegas.

TVs kept their New Year’s resolution to slim down. Samsung and LG both showed off 55″ OLED models.  The latter goes home with CNET’s Best in Show award.

“It’s a much brighter, much truer color technology that’s razor-thin, and basically has pure black.  Thin as you can possibly imagine.”

Four millimetres thin, says CNET senior editor Scott Stein (on Skype, from the convention floor).  They picked the LG because it adds streaming video and social media access, and passive 3D — which means you don’t need those heavy, battery-powered glasses to see the special effects.

It’s not expected in stores until late fall, and you might need that long to save up.  The price to be an early adopter should be in the $8000 range — though it’s expected to fall to earth over the next several years as this technology wins more eyes.
