More on Electronic Paper

Two weeks ago, I wrote about a Massachussets-based company, E Ink demonstrating a new electronic paper system using plastic transistors from Lucent. Xerox is now entering the market of electronic paper. Creating a company called Gyricon Media Inc. that will promote an e-paper technology originally developed at the Palo Alto Research Center.

Gyricon's technology works with small beads embedded in a sheet of transparent plastic. The beads are white on one side and black on the other, and are electrically charged so that they rotate to show one face when a voltage is applied. A voltage pattern is applied using an attached sheet of electrodes or by running the beads through a printer-like device, making an image that remains until a new one is created.

New Company to Use PARC Technology to Create Digital Display Documents

PALO ALTO, Calif., Dec. 6, 2000 -- Xerox Corporation (NYSE: XRX) today launched Gyricon Media Inc., an independent venture that will use the power of electronic reusable paper to provide networked, reusable retail signs that can be updated with the click of a mouse. The electronic signs can be used for in-store shelf displays, promotions and billboards and will be followed by an array of products in such areas as digital publishing and portable device displays.

Gyricon Media Inc. is charged with commercializing Xerox's digital document display technology that is as portable and flexible as a plain sheet of paper. The company will initially use the technology to develop applications for signage and point-of-purchase displays found in supermarkets, department stores and other retail outlets.

Electronic reusable paper was developed at the renowned Xerox Palo Alto Research Center (PARC) and is supported by a portfolio of Xerox patents. Named after the technology that is the basis for electronic reusable paper, Gyricon Media (JYE-rih-con) will manufacture a new kind of document that, like paper, is thin, lightweight and inexpensive.

However, when combined with the appropriate electronics, the material is capable of displaying and changing text and graphics like a computer screen - and can be reused thousands of times.

"Electronic reusable paper is really the paper of the future. It will dramatically change the way people think about printing, and it will revolutionize the way that stores communicate prices, promotions and other information to their customers," said Bob Sprague, interim chief executive officer of Gyricon Media, and manager, Xerox PARC's Document Hardware Lab. "The company's initial products will be battery-operated signs and
