In the race for ever-thinner displays for TVs, cell phones and other gadgets, Sony may have developed one to beat them all - a razor-thin display that bends like paper while showing full-color video.Sony Corp. released video of the new 2.5-inch display Friday. In it, a hand squeezes a display that is 0.3 millimeters, or 0.01 inch, thick. The display shows color images of a bicyclist stuntman and a picturesque lake.Although flat-panel TVs are getting slimmer, a display that's so thin it bends in a human hand marks a breakthrough.Sony said it has yet to decide on commercial products using the technology."In the future, it could get wrapped around a lamppost or a person's wrist, even worn as clothing," said Sony spokesman Chisato Kitsukawa. "Perhaps it can be put up like wallpaper."
