LONDON — Philips spinoff Polymer Vision Ltd. is working with Telecom Italia Mobile to launch the first mobile device with cellular connectivity and a roll-out screen.

The device is being described as a Cellular Book and makes use of the same 5-inch scrollable display that Polymer Vision demonstrated in the Readius prototype shown at the Internationale Funkausstellung (IFA) consumer electronics exhibition held in Berlin in September 2006.

Polymer Vision (Eindhoven, The Netherlands) rollable display technology enables mobile devices to incorporate a display that is larger than the device itself. Working with E Ink Corp., the company demonstrated a handheld device with a roll-out electronic display. It includes 16 levels of grey scale and is readable in bright sunlight, Polymer Vision claimed. However, the display of color and moving images are not yet possible, the company said.

TIM is offering the ability to download entire newspapers and books to the e-reader, which will include 4-Gbytes of memory in the initial model. The unit which will include DVB-H and cellular EDGE capability will also allow receipt of email and RSS feeds and location-sensitive maps, Polymer Vision said. This will allow the downloading of music and audio podcasts. The terminal has been designed to provide an average of 10 days usage time between battery charges.

Telecom Italy will market the Cellular Book on an exclusive basis while Polymer Vision will market the device in the rest of the world.
