e-ink gains momentum

According to Technology Review, e-ink R&D has completed a working prototype of their product using silicon.


    Researchers at Cambridge, MA-based E Ink have completed the first working prototype of an electronic ink display attached to a flexible, silicon-based thin-film transistor backplane, the sheet of electronics that controls display pixels. The prototype is a functional display that you can twist, bend or throw against the wall without disturbing a single electron.

    This proof-of-concept prototype confirms that it will soon be possible to mass-produce reams of self-erasing electronic paper that combine sheets of electronic ink with flexible silicon circuitry. Last year, Lucent Technologies demonstrated an electronic-ink display driven by flexible plastic transistors, but E Ink researchers believe that silicon-based transistors have several big advantages over plastic.

    The company's ultimate goal is to produce RadioPaper, sheets of reusable e-paper containing radio frequency ID tags that download a new edition of, for example, the Wall Street Journal each morning into the same physical display.
