GadgetsWe haven't seen all that many OLED lighting options, but a group of researchers from the University of Michigan and Princeton University say they could be on the verge of changing that situation, with them now boasting of a new breakthrough that could greatly increase the efficiency of OLEDs. The key to that, it seems, is a combination of an organic grid and some tiny dome-shaped micro lenses that guide the trapped light out of the devices. As the researchers point out, with current OLEDs, only 20% of the light generated is actually released, but they say this new method could boost the efficien
