If anyone wants to look it up on youtube, search for "graphene flexible oled screen Samsung Microsoft" on youtube. I believe they demo'd the prototype in 2013.
You know annoying, now when you search it, you only get samsungs half of the announcement. lol. Before, the whole talk included Microsoft showing windows and a windows game running on a scrolling screen. Now its basically impossible to find.
The Microsoft speaker also showed how the screen was more or less indesctuctible, a basic property of graphene. Which is a silly thing to miss out. AND it was filed at a better angle.
But anyway despite the fact it cuts the second part of the talk (which may even be corporate work, perhaps they don't want this widely known any more, and the filming of the demo is all crowd people) -
Here's the proto-
This is also where they came up with the curved screen (Samsung). Which is basically a useless gimmicky use of the tech while they are waiting for the real technology.
But as I say, manufacturing costs of graphene is the current obstacle to folding displays. A super material, than when cheaply made will revolutionize A LOT more than computing (nanomanufacture, water filtration, battery circuit tech, chemical manufacture, space vehicles and super materials etc etc).
In computing its pretty important for MS. Because it scales the pocket device up to the sort of size where windows 10 and apps seem better suited, and android/ios and apps less. A size where simple apps seem, well simple. It's also important because apple and google don't have the patent. Only Samsung and MS. And obviously, beyond voice, its the next step. It will probably pretty much kill apple.
