Meet the RollRR: a giant, rollable display for mobile devices. It is designed for folks who need to have a larger display to consume the content on their mobile device. What’s neat is you can fit it in your bag without having to make a big compromise. The prototype that Engadget covered is a 10.7″ e-paper display but the goal is to fit a much larger screen into an umbrella-sized gadget. The folks at Engadget have plenty of photos and information on the device at this time.
