The screen is based on OLED (organic light-emitting diode) technology and is intended for advertising and public display applications. It will go on sale worldwide from Sept. 21, which is almost a year to the day since Mitsubishi first showed off a prototype (YouTube video) of the technology at Japan's Ceatec electronics show."
