September 5, 2005 After many years of R&D in rollable displays, Philips revealed its Concept Readius at the Internationale Funkausstellung (IFA) in Berlin, Germany last friday. Philips Concept Readius is a prototype of a connected consumer device for business professionals unwilling to sacrifice readability, mobility, performance, or weight in a pocket-sized, e-reader concept. 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.
