Konica Minolta does have big plans for OLED lighting.
Konica Minolta want to lanuch OLED lighting equipment in March 2011 and want to build a large scale plant for lighting panels in 2014. The forecast for organic lighting in 2017/2018 is about 1.1 billion Dollar!

Management at Konica Minolta is committed to making OLED lighting one of our major business pillars in the mid to long term," senior executive officer Shoei Yamana told a group reporters on Thursday. His remarks were embargoed until Friday.

Konica Minolta expects OLED lighting to replace traditional lighting fixtures such as fluorescent lamps as production expands and costs come down.
