E Ink is showing a prototype of a flexible screen with a black and white resolution similar to that of today's laptops. The screen can be rolled into a tube approximately 1/2" in diameter and then rolled back out for use.

Although the refresh rate on the device is only 4Hz, the company says they expect to get that above 40Hz before long.

It's unclear what this display will be used for, but the folks at Wired have some further information and comment in an article available today.
