Smartphone screens can be bendable, rollable and foldable.
Youm
Samsung debuted Youm, its flexible, bendable and foldable OLED display for smartphones during CES 2013.
Stephen Woo, president of Samsung and Brian Berkeley, senior vice president of Samsung Display, showcased the new screen technology during the South Korean electronics giant's keynote.
The bendable OLED technology, named Youm, utilizes thin plastic as opposed to glass, subsequently allowing the display to become bendable, flexible, foldable and an almost unbreakable screen. As well as Berkeley displaying a prototype, Microsoft CTO Eric Rudder also showed a prototype Windows Phone with the flexible screen.
"This new form factor will really begin to change how people interact with their devices, opening up new lifestyle possibilities ... and allow our partners to create a whole new ecosystem of devices," said Berkele.
The Galaxy S4 is rumored to be the first Samsung device to feature an unbreakable screen.
Sometime last year, or maybe even in 2011, I believe nokia had a video that Toms did an article on about a bendable device using a bendable screen prototype. It showed gestures for zooming in and out on photos based on concave and convex bending. Also twisting it certain ways had functionality. The only thing they couldn't put in the device was a batter so they had it hooked up to a power source.
