Philips showed their prototype roll-up screen a couple of years ago. Now they are starting to manufacture their first device using the display - a mobile phone with a 5" screen. This technology will be huge. Imagine a small pocket device that you can whip out and expand to provide you with a large screen. Watch the video after the jump...

" The 5-inch (13-cm) display of Polymer Vision's "Readius" is the world's first that folds out when the user wants to read news, blogs or email and folds back together so that the device can fit into a pocket."
