A sliver of the future can soon be tucked into your back pocket. For years, researchers have worked on thin, paperlike displays that can be folded, rolled or sewn into the sleeve of your hoodie. Flexible displays could change the way we interact with the info-universe, creating new kinds of cellphones, portable computers, e-newspapers and electronic books

This year, the research moved from the realm of science fiction to plausible reality. With help from the U.S. Army, Arizona State University's Flexible Display Center has created a prototype for soldiers, and hopes to have the devices in field trials in the next three years. Startups like Plastic Logic and E-Ink have been developing similar technologies.

Meanwhile, Hewlett Packard announced a manufacturing breakthrough that allows the thin-film transistor arrays to be fabricated on flexible plastic materials, enabling manufacturers to "print" displays on big, newsprintlike rolls. Samsung showed off a mobile phone prototype with a flexible display that folds like a book.

Outlook: A Minority Report-style digital newspaper that you can roll up in your pocket isn't happening before 2010 at the earliest. But to quote science fiction novelist William Gibson: "The future is here. It's just not widely distributed yet."
