Polymer Vision has created a new rollable screen that measures 6 inches. The screen has an SVGA resolution of 800x600 pixels. The screen is flexible enough to comfortably roll around a dime.
The screen has a lifetime of about 25,000 uses.
Polymer Vision has created a screen (a few years ago now) in colour although that particular screen was a lot smaller than this new version. The video below gives a demonstration of how it works. As can be seen, there's still a while to go before this technology hits main stream, but I have to admit that it still impresses me that a screen can be made so thin and flexible that it can be rolled up.
