Phillips Rollup Display

During the 2006 International CES, Philips showed this prototype of a device continually rolling and unrolling a display for the control panel of a PocketPC.

The grayscale, non-touchscreen screen is 320 x 240 pixels, with a diagnal length of 5 inches.

Can you imagine the applications for reading gadgets? eBooks? Or even the cost savings of putting these things into a budget Pocket PC?

Anyway, don't take my word for it--have a look for yourself over at Geekzone.
