Organic Light-Emitting Diodes (OLEDs)

Organic light-emitting devices (OLEDs) have a broad range of applications, ranging from interior lighting, displays, and automobile devices. They offer high contrast colors with wide viewing angles, fast response times, and thin, flexible structures.

The basic OLED consists of thin organic layers angstroms in thickness, sandwiched between an anode and cathode. When a potential is applied, the injected positive and negative charges recombine in the emissive layer to produce light. Particular structures of the organic layers and the choice of anode and cathode are chosen to maximize the recombination process in the emissive layer, thus maximizing the light output from the OLED device.
