Apple filed a new patent that describes a fascinating elastic haptics display. The idea is that the screen can not only provide tactile feedback (using vibration, etc.) but change its shape to form real 3D buttons, markings and even maps. Pretty cool.

Apple does say that any suitable flexible display panel can be used, for example graphene based display. But it seems that OLED is the most mature technology when it comes to such flexible displays.
Apple has been patenting OLED displays for quite some time, just a few weeks ago we reported on a new OLED brightness control scheme.
