Toray Industries is showing a Samsung-made 4.6" flexible OLED panel - which uses Toray's "component". We're not sure exactly what component Toray is talking about. We know that Toray is working towards Polyimide-based OLED encapsulation, but the company also develops blue OLED materials (at least the did back in 2008) - so perhaps Samsung are using their emitting materials? After all we know that Samsung are collaborating with Ube Kosan on Polimide development.
In any case, this OLED was showcased in Tokyo in a Toray's latest-technology exhibition. This OLED on show seems to be the same one unveiled back in November 2010 - a 4.6" WVGA panel (you can see this panel on video below).
