BASF and OSRAM ticked the OLED
progress meter up one recently, with news out of Germany about new diodes that are both efficient (60 lumens per watt) and reproduce color accurately enough to meet international Energy Star standards. The most power sipping organic light-emitting diodes ever created they aren't, but the ability to keep their color
under varying levels of intensity leads to the next step, producing stable deep-blue colored emitters for increased efficiency (100 lumens per watt or more) so they can start illuminating surfaces near you. Isn't it lucky, we know some folks in South Korea
BASF might want to have a chat with.
