    E-paper bandwagon gathering steam
    LOS
    ANGELES — Epson emerged at the Society for Information Display
    conference this week as the latest in a string of E Ink Corp. licensees
    bringing e-paper products to market.The company demonstrated several
    active-matrix electrophoretic displays (EPD), based on low-temperature
    polysilicon (LTPS) thin-film transistors, with unusually high
    resolution. Creating a high-res image that looks like ink on paper was
    motivated by the company’s traditional involvement with real paper in
    the printer business, a company spokesman said.

    Epson
    demonstrated a 6.7-inch-diagonal display with a 1,200 x 1,600-pixel
    format, yielding a resolution of approximately 300 pixels/inch; and a
    13.4-inch-diagonal display in a 3,104 x 4,128-pixel format with 385
    pixel/inch resolution.The company has e-book reader applications in
    mind, and it is also exploring other e-paper applications that would be
    “thinner and lighter than e-books.” The combination of E Ink’s EPD
    technology and Epson’s LTPS technology, the spokesman said, enables the
    fabrication of displays that are “as big as one might want them to be.”
    Commercialization is expected “soon.”As for E Ink itself, that company
    demonstrated its latest design win at its SID booth: a Hitachi
    cellphone with a display “skin” that lets users personalize their
    phones. The phone offers a choice of 95 different patterns on its front
    face, including a butterfly that moves across the screen and grows when
    the phone rings.Kent Displays Inc. demonstrated a concept cellphone at
    SID that uses this company’s cholesteric-LCD e-paper technology to
    personalize a phone. In this case, a stack of red, green and blue
    subdisplays gives the user a choice of front face colors: eight colors
    in the demo but a bigger pallet is also possible, according to a
    company spokesman.
