WHEN YOU’RE FINISHED reading your e-mail or the newspaper on that big, five-inch screen, wrap it up and stow it in your pocket. Polymer Vision’s Readius, a cellular-connected, PDA-size gadget, is the first device available with a roll-up display. Instead of glass, it’s made from a plastic sheet. The company concocted transistors out of durable polymers, layered with gold wires, to minimize stress when the display bends, so it can survive tens of thousands of flexes.The screen uses a technology called E Ink, which floats pigme
nt to the surface of tiny capsules to produce black-and-white text or images in 14 shades of gray. Adding red, green and blue capsules will give the device a color screen by 2009. And Polymer Vision expects to have a display that can refresh fast enough to handle Webpage scrolling and basic video by 2010.Audio is also catered for, with podcast and music downloads supported. Future models should be able to display colour and live video. Navigation is carried out through a touch-sensitive LED array, designed to be used single-handedly, and battery life should be an astounding ten days on average.
A built-in SIM card slot means it can be constantly connected to an EDGE/UMTS network as well as DVB-H IP data-casting, and take advantage of e-mail, news, location sensitive maps and ebooks, as well as user-loaded information on the 4GB of internal storage transferred via mini-USB.
