In comparison, E-ink's best screen can do close to 15 fps, at 16 shades of gray.
As you can see in the gallery below, the demo unit is impressive more for what it promises might come in the future, rather than what it can do now. It's not very high resolution, though it colorful.
There's still no news on who will license the tech and actually produce the screens, but I do know that PlasticLogic won't be building it; they are looking to license the tech once it is fully developed.
PlasticLogic's flexible AMOLED screen tech is being developed in partnership with NovaLED, a specialist in OLED and AMOLED technologies. They contributed the expertise to build the half of the screen which is visible to the naked eye, while PlasticLogic contributed the rear of the display, or backplane.
Update: PL posted a promo video on Youtube.
