Samsung previews foldable, rollable 'Youm' smartphone displays

Samsung Electronics showed some of its prototype flexible displays at CES and launched a new brand name for them, Youm. A Samsung engineer showed a prototype smartphone fitted with one of the displays, which wrapped around the device to cover the left and right edges. It means if the phone were lying face down on a table, important messages could be displayed running along the edges, like a ticker display."
