is revealing a new rollable display at the Internationale Funkausstellung (IFA) in
Called the ’Concept Readius’, it is claimed to be 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 grey levels, the monochrome, 5-inch QVGA (320 pixels x 240 pixels) display provides paper-like viewing with a high contrast ratio.
Using a bi-stable electrophoretic display effect from E Ink, 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.
Based on Philips Polymer Vision’s PV-QML5 rollable display reference design, the Readius was created in order to demonstrate the viability of the rollable-display concept in mobile applications and to gain customer feedback at the IFA show.
Polymer Vision has no plans to actually commercialise the prototype.
