Mitsubishi announced they completed the installation of Japan's largest digital signage system at Narita international airport in Tokyo (announced in October 2011). The system includes a 160-degrees concave Diamond Vision OLED display called Panorama Vision. This cool display measures 9.6 x 1.9 meters and is made from 2,000 96x96mm PMOLED panels.
This is Mitsubishi's third Diamond Vision OLED installation that we know about. The first one was a 3.84x2.3 meter display installed at Merck's research center and the second was the 6-meter Geo-Cosmos sphere installed at Tokyo's Science Museum.
