The CEATEC in Japan is always a playground for advanced prototypes. Bendable OLED Displays have been the topic of prototypes for a couple of years now. Sony shows at the CEATEC 2009 a nice design of a notebook that only has a bendable OLED display inside the covers.
This design would of course be ideal for the implementation of the Microsoft Courier dual screen Tablet concept.
AkihabaraNews is at the CEATEC 2009 and has published a couple more photos of Sony OLED prototypes.
