OLEDs are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. They’re so thin, that they could be applied to rooms as a type of wall paper to glow at the touch of a finger or when someone enters the room. Like LEDs they produce light very efficiently. But OLEDs also have to potential to be made at a very low cost, because they can be printed “roll-to-roll” like a newspaper. GE recently demonstrated the first OLEDs to be made in this manner — the researchers worked for four years on this project. See more at the GE Blog.
