Diamond Vision OLED is a modular display (100" or larger) for outdoor use which tiles small PMOLED panels. Mitsubishi has two kinds of modules: 384x384mm (128x128 resolution) and smaller 96x96mm (32x32) ones - which can be used to create curved or spherical displays. Each pixel is about 3mm in size - you need to view the displays from at least two meters away. The Diamond Vision is bright (1,200cd/mÂ²) and has a good contrast (twice as better as LED, says Mitsubishi) - so it can be used in brightly-lit areas such as airports or stations. The OLED materials were jointly developed by Mitsubishi and Pioneer.
Mitsubishi is selling Diamond Vision OLEDs since September 21st, 2010. The first installation is a 3.84m by 2.3m with a 1280x768 resolution (60 modules at 128x128) display at Merck's research center. The second one is the Geo-Globe, a 6-meter sphere at Tokyo's Science Museum - and it has 10,362 panels - each 96x96mm in size - total resolution is more than 10 million pixels.
