There's an interesting article over at EETimes, about Samsung's VP of OLED R&D Center, Brian Berkeley (an ex-Apple engineer). They say that Berkeley's presence in Korea is a proof of Samsung's commitment to lead the industry by recruiting the "best and the brightest" from all over the world.
According to EETimes, Samsung is very confident in the future of OLEDs, not just for small displays, but also for large TVs, especially 3D TVs. OLED TV is no longer a "science fair" project for Samsung. according to Berkeley: "Large-size OLED TVs are viable".
