Computerworld takes a look at the development and the future of e-paper. Brought into the mainstream by e-book readers such as the Kindle, e-paper is rapidly becoming its own industry. The article notes some of the current limitations of the technology and looks ahead to a few of the upcoming ideas, such as the Fujitsu Fabric PC. Quoting: "The resolution of EPD screens is improving rapidly. Active-matrix displays like those used on the current generation of e-book readers can work at relatively high resolutions (the Kindle screen displays 167 pixels per inch), and Seiko Epson recently showed off an A4-size (13.4-in.) display prototype with 3104 by 4128 resolution, about 385 ppi, that uses E Ink's electrophoretic ink on a Si-TFT glass substrate."
