Lately, Osram has made two breakthroughs on OLED.
One breakthrough is that, testing under application-oriented conditions in an integrating sphere, the company has achieved 87 lm/W with its OLED in the lab. In contrast to the previous achieved peak value, this efficacy is about 40 percent higher or nearly the efficiency of fluorescent lamps. And the OLED was measured at a brightness of 1,000 cd/m2 and a color temperature of approximately 4,000 K.
The company also achieved almost 75 Im/W at a brightness of 5,000 cd/m2 in another test. It has already tested the organic functional material in pilot manufacturing and enables product-relevant lifetimes. The OLED laboratory sample was prepared using a pure thin-film approach.
