An electronic paper display is a specialized type of electronic paper that combines the uses and advantages of a computer display and paper. Electronic paper displays are extremely thin, use minimal amounts of power and provide a high-contrast viewing surface like paper, but can be easily updated like a monitor. Siemens unveiled a cheap electronic paper display that can be printed on paper and foil in 2005, during the Plastics Electronics trade fair in Frankfurt. These displays were at that time set for launch during 2007. The SONY LIBRIé was the first commercial product to make use of an EPD. This device is basically the electronic equivalent of a book and was launched on April 2004 in Japan. Electrochromic EPDs use electrochromic substances that change color when an electric voltage is applied. Displays are comprised of an electrochromatic material that holds a series of electrodes, backed by a layer of conductive plastic foil and a second layer of electrodes. The future of EPDs is... less
