Samsung shows alongside the 14-inch and 31 inch OLED Panels a new OLED TV prototype a 40 inch FULL HD OLED Television.

Samsung SDI has been working on its prototype 40-inch OLED screen, already the largest OLED screen yet seen, and the latest model now offers full high definition.

Sporting a sign proclaiming "The world's 1st, world's largest," the display caught the eye of many show attendees and there was often a small crowd gathered around the family of prototypes.

Samsung first announced development of a 40-inch OLED panel in 2005. At that time the screen had a 1,280 pixel by 800 pixel resolution but the new panel has full high-def 1,920 pixels by 1,080 pixels, which in addition to being higher resolution than the previous model is also a TV panel resolution while the previous screen was a computer panel resolution.

Another change between the two models is a big jump in contrast ratio, from 5,000:1 on the previous prototype to 1 million:1 on the new screen. The panel does have a color gamut of 107% NTSC and a luminance of 200cd/m2 (peak luminance of 600cd/m2)

Samsung saiys that the low temperature poly-Si TFT mass-production line cannot make panels larger than 31 inches," a Samsung staffer said. "This 40-inch TFT panel is the largest size that can be made on our pilot line, and it cannot be mass-produced right away."
