InfoWorld - "Fujitsu has made progress in its development of flexible, paper-thin displays that consume very little power. The company unveiled its latest prototype on Tuesday, a 7.8-inch panel that can display up to 4,096 colors. The display, which is the same size as a sheet of A5 paper, was built into a thin case in the form of an electronic book reader. It was on display at the Ceatec show, which opened on Tuesday. The e-book reader was rigid, but the flexibility of the displays could offer an advantage in other types of applications. Fujitsu offered the example of an electronic advertising panel that could curve around the top of a train or subway car. The display area of the prototype shown at Ceatec was about four times as large as that of another prototype Fujitsu showed in the middle of last year. "
