Imagine curling up on the couch with the morning paper and then using the same sheet of paper to read the latest novel by your favorite author. That's one possibility of electronic paper, a flexible display that looks very much like real paper but can be reused over and over. The display contains many tiny microcapsules filled with particles that carry electric charges bonded to a steel foil. Each microcapsule has white and black particles that are associated with either a positive or negative charge. Depending on which charge is applied; the black or white particles surface displaying different patterns. In the United States alone, more than 55 million newspapers are sold each weekday.
