I saw those things in another video, when the concept was first... I don't know, revealed, I guess. I forgot what company. Whatever.
It's like, it's some kind of material or something like that, that can be bent and cut into shapes and still be a screen. Or something to that effect.
The notable thing about it, to me, was that it works in such a way that you can see the image clearly from lots of different angles. On most screens, the image gets color inverted or something weird when you're too far to the side of it, or below it.
Bleh. They used the same material or something like it make bracelets that had marquees, or something.
