Oh, Sorry, no, afaik Cree does not do OLED technology at all. They are basically a semiconductor company. I'm into lighting, not displays. I have heard you can buy OLED TVs, but its bleeding edge - like a 24 in screen for $10 k or something (I'm making that up).
OLEDs are tough - you have to be able to keep air out of them, but they are meant (generally) to be flexible. Some plastics are clear, flexible, cheap, and impervious to oxygen, but very few =)
