Watch Samsung's entire CES keynote and marvel at the YOUM flexible displays

The bendy screens are made with a plastic, instead of glass, substrate, which makes them durable, and allows Samsung to fold them in half, taper them to the sides of your phone, or roll them up in a tube.

They also showed a flexible screen prototype, running Windows Phone 8, so that we don't think these are only for Android devices, and there were many more surprises, including the former President Bill Clinton taking up the stage to talk tech and charity cooperation between his Clinton Foundation and Samsung's giving initiatives. Enjoy - the Exynos 5 Octa talk starts at 12:34, and the YOUM display prototypes demo at 39:47.
