Called the Philips Readius it is a hand held e-paper device where when the device is closed the screen is rolled up making is small and compact (relatively). When the user opens the device the screen is unrolled making the screen bigger than the device itself.
The Readius is the world’s first prototype of a functional electronic-document reader that can unroll its display to a scale larger than the device itself. With four gray levels, the monochrome, 5-inch QVGA (320 pixels x 240 pixels) display provides paper-like viewing comfort with a high contrast ratio for reading-intensive applications, including text, graphics, and electronic maps. Using a bi-stable electrophoretic display effect from E Ink Corp., the display consumes little power and is easy to read, even in bright daylight. Once the user has finished reading, the display can be rolled back into the pocket-size
(100 mm x 60 mm x 20 mm) device.
Nice idea. Unfortunately despite what the video says it is only a concept device and wont itself make it to market. It is designed to show what e-paper can do and hopefully the design will be used in real devices.
