“A Gyricon display consists of millions of microscopic, charged balls painted half-black, half-white. The balls float in tiny liquid-filled cavities and rotate in response to an electrical field. Just like ink dots on laser-printed paper, swaths of these balls can form patterns, characters, and pictures. But unlike ink, the balls can be rearranged again and again.”
“They're working on ‘electric paper,’ a fabric-like material that can display digital text. The "paper" is flexible. It uses far less power than a laptop display. It can achieve resolutions as good as a laser printer. Perhaps most important, it can eventually be made for US$1 a page -- a minuscule fraction of what it costs to make a LCD display.
Xerox (XRX) is tight-lipped about possible products. But use your imagination: wallpaper that changes patterns at a decorator's whim; billboards that change ads for weekday and weekend commuters; radio-controlled grocery store shelf tags for diaper happy hours; or ‘electric newsprint’ that wirelessly downloads the hourly editions of The New York Times and The Wall Street Journal.”
