The prototype designed and built by researchers at the Samsung Advanced Institute of Technology in South Korea was vigorously tested against 100,000 folding-unfolding cycles. The results of the trial produced no visible crease and the screen’s brightness at the pivot line only decreased by 6%.
The AMOLED display itself consists of two panels place on the bottom and top of layer of silicone rubber. A protective glass cover is then placed over the optic sandwich to protect it from scratches and allowing display to act as a touch screen. All the components were placed inside of a case that folded to a 180° angle, which positioned the two panels on top of each other.
As NetworkWorld notes, Samsung's been talking about this sort of technology for a while, including at this year's CES.
It’s not exactly the one piece, roll-able color screen of the future, but at least it’s a step foward from a Nintendo DS or a Kyocera Echo.
