Samsung thin TV

Flat-panel TV makers are locked in a battle to make ever-thinner sets, and it was Samsung that delivered the slimmest at CES. Its new Luxia sets are between 6.5 and 7 millimeters thick across the body and were demonstrated in screen sizes of 55, 46 and 40 inches. The sets have an LED backlight, which means they use a bank of LEDs behind the screen to create the light shone through to illuminate the image on the display. Samsung hasn't announced when they might be available.

Sony Flexible OLED

A flexible color OLED (organic light-emitting diode) screen that could be used in future highly portable electronics devices was one of the R&D highlights at Sony's booth. The 2.5-inch screen was manufactured on a thin sheet of plastic, so it's 0.2 millimeters thick and can be gently bent while it's showing video. The prototype screen has a 160-by-120 pixel resolution and weighs just 1.5 grams. It's not likely to appear in products for several years.
