Samsung develops foldable mobile phone with big OLED screen


Samsung has been playing around with flexible displays for several years, as has Sony, but now Samsung has developed a working prototype of a mobile phone which uses a foldable OLED screen to enable a much larger display to be fitted into a handheld device.

Take a look at the device when it’s closed and it looks like a fairly standard handset with a general-purpose display on the front. Unfold it (as shown in the video below) and you have access to a much larger screen for playing movies and games.

The advantage of using flexible material is that you end up with a seamless display rather than two separate ones. I could see this being expanded to create even larger displays that can be folded away into a sensibly-sized mobile phone handset, or perhaps built in to other portable devices such as netbooks and DVD players…
