Here's a new technological entry that is making opticians rub their hands with glee. Last week Sony Corp. revealed its newest development -- a razor-thin display that bends like paper and shows full-color video. The 2.5-inch video screen is only 0.3 millimeters thick. To us American neophytes that's equivalent to a thickness of 0.01 inch.

The new display combines two different technologies, which seemed to have come directly from an episode of Star Trek: Sony's organic thin film transistor, which is required to make flexible displays, and organic electroluminescent display. Other companies, such as LG and Phillips, also have plans for paper-thin displays. However, according to representatives at Sony, the organic electroluminescent display delivers better color images and is more suited for video. As to what the display will be used for, a spokesperson for the corporation mentioned that they could be wrapped around a lamppost, or a person's wrist, or put up in someone's house like wallpaper.
