Organic light emitting diodes, or OLEDs, promise to bring a great deal of flexibility to where we can put a display—literally. Because of their organic components, it should be possible to create flexible and transparent displays, opening up a large number of potential uses. But now, just as OLEDs may finally be ready for the consumer market, some engineers have figured out a way to get many of the same properties using inorganic LEDs (ILEDs), using a method that's so simple, even a biologist could understand it. It's a few years away—at least—from commercialization, but it's a significant advance.
