We had the opportunity to check out Samsung Display's latest concepts at Mobile World Congress, including tri-fold tablets, folding gaming handhelds, and even a screen that stretches.

Samsung is also showing off a few devices with tri-fold displays the size of small tablets. The Flex S screen folds like a map (with one portion of the screen folding inward and the other outwards, making it look a bit like the letter S). And the Flex G has two hinges that fold inward instead.
