@jamesuschrist: If I understand correctly, this work is aimed at increasing the efficiency of white LED lighting panels for commerical and domestic illumination, not for OLED screens.

Incidentally, UDC has already achieved 100 lumens/W in their phosphorescent OLEDs. Their being partly funded by a Dept. of Energy initiative that's aiming to get 150 lumens/W to the market by 2015.
