Abstract
Since the first breakthrough at Eastman Kodak in 1987, the field of organic electroluminescence has advanced at a dramatic pace to the point where polymer displays are now commercially available. Research has concentrated on reducing the voltage needed to drive organic displays, and on increasing their lifetime and efficiency. A recent experiment in the US demonstrates the rapid rate of progress in the field. Stephen Forrest and co-workers at Princeton University and the University of South California have overcome various hurdles to build an efficient organic light-emitting diode (LED) that operates at high speeds (MABaldoet al. 2000Nature 4O3 750).
