Electronic Papyrus: The Digital Book, Unfurled

Put a bigger screen on a cellphone or an e-reader, and soon it outgrows pocket size. Now a hallmark feature of these screens — their rigidity — is changing. New technologies are developing that make displays flexible, foldable or even as rollable as papyrus, so that large screens can be unfurled from small containers.

O’Rourke of the Flexible Display Center likes the look of the new generation of supple screens, but he also likes their toughness. “Some of them we’ve beaten with hammers, and they still run,” he said. “No one could do that with a BlackBerry.”
