Osram Opto Semiconductors GmbH, Regensburg, is a wholly owned subsidiary of OSRAM, a leading supplier and manufacturer of lighting solutions who employs more than 35,000 people throughout the world.
OSRAM released the world's first OLED lamp back in 2008, but this was more of a prototype than a commercial product. In November 2009 they have started to ship their first OLED lighting panel, the ORBEOS, and here's our hands-on review of those panels. OSRAM is currently mostly involved with OLED lighting for the automotive market.
OSRAM used to offer PMOLED display panels (under the Pictiva brand), but this is now discontinued.
