If you're tired of squinting at that postage-stamp-sized screen on your cellphone, Polymer Vision is pimping a 4.8-inch roll-up screen for cellphones, GPS, and mobile entertainment devices, and maybe someday it will make its way to the real world. This fanciful mockup is said to have a 240x320 color screen with a refresh rate of 50Hz. One look at that picture above, and you can see the potential of something like this. Wow.

Meanwhile, back in the real world, we first saw one of Polymer Vision s devices at CES (pictured here) this January, where the company was demonstrating a prototype in the Philips booth. Called READIUS, it s a 5-inch black-and-white rollup display that Polymer Vision said was not intended to be a product but just a demonstration. While it was thin and did actually roll up, its contrast was low and it was a pretty rough first outing. From what we saw with our own eyes, looks like the company has quiet a long way to go before we see these bright color screens on cellphones and GPS devices.
