The CEATEC 2011 (http://www.ceatec.com/2011/en/) exhibition started today in Chiba (just outside of Tokyo), and what I saw was either disappointing (like gear that's already available in stores) or already widely covered, as most Japanese companies pre-announced almost all novelties (for example, Docomo's awesome smartphone jackets (http://techcrunch.com/2011/09/22/ntt-docomos-cases-make-smartphones-measure-radiation-body-fat-alcohol/)).
One exception was Mitsubishi's so-called "Diamond Vision OLED", a semi-spherical display boasting a diameter of 2.7m. It's very similar to their huge OLED globe (http://techcrunch.com/2011/06/02/geo-cosmos-mitsubishi-electric-shows-6-meter-oled-globe/) that's currently on display in Tokyo's National Museum of Emerging Science and Innovation (http://www.miraikan.jst.go.jp/en/).
This new model consists of a total of 696 OLED panels, each sized at 32 x 32mm. Sized at 96 x 96mm, the OLEDs forming the aforementioned globe are considerably larger, but the panels share the same pixel pitch (3mm).
Mitsubishi said that the Diamond Vision OLED has a brightness of 1,200cd/m2 and consumes 11.2kW of power. The company plans to commercialize the display for digital signage systems.
