World's Biggest Spherical OLED Display Set for Japan Debut

Thin, bright OLED displays already offer the promise of roll-up TVs or tablets, but the Mitsubishi Electric Corporation has taken flexibility a step farther by creating the world's first large-scale spherical OLED display.
Mitsubishi's "Geo-Cosmos" display stretches about 20 feet (6 m) across and shows a video of the surface of the entire Earth. The organic light-emitting diode (OLED) globe will display clouds and similar heavenly visions of our planet taken from a satellite when it debuts in front of crowds at the National Museum of Emerging Science and Innovation in Tokyo, Japan on June 11.
Such projections will feature a resolution of more than 10 million pixels, or about 10 times greater than that of a light-emitting diode (LED) display. The secret behind the quality images comes from 10,362 OLED panels covering the aluminum sphere, with each panel barely 4 inches wide.
Long-lasting LEDs have already begun to spread in electronic device displays and light bulbs due to their energy efficiency. The newer OLEDs offer brighter light with a crispier color contrast, as well as the possibility of being printed on flexible plastic displays.
Of course, museum goers will probably just care about staring at the shiny, lit-up globe hanging almost 60 feet (18 meters) above their heads.
