Eindhoven, Netherlands - Polymer Vision, a spin-off of Philips, has announced the development of the world's first "rollable" display for mobile devices, which it plans to display at the 3GSM World Congress next week in Barcelona. While the device itself is smaller than a typical mobile phone, it features a display that can extend up to 5-inches, and then roll back and wrap itself around the outer shell of the device when not in use. Polymer Vision said it partnered with wireless carrier Telecom Italia to offer the first rollable display-enabled mobile device later this year.
