Innovations in the development of organic LEDs, or OLEDs, could soon make the technology more practical as a substitute for traditional fluorescent bulbs. Companies are improving light output and developing less expensive manufacturing techniques. OLEDs should also get more affordable as the scale of production increases.
Last week, Stephen Forrest, a professor of materials science and engineering at the University of Michigan, published work on a more efficient, longer-lasting blue material that might solve this problem.
“OLEDs produce a beautiful sheet of light,” Forrest says. “I believe OLED lighting will be a very important lighting source in the future, perhaps a dominant one. But there’s a big gap between what we can do now and what we need to get costs down.”
