Abstract

Organic light-emitting diodes (OLEDs) are films of organic molecules, 100s of nanometer thick, that emit light in response to an electric current. Thanks to their mechanical flexibility, they are fast replacing the traditional rigid devices with flexible ones; they include flexible mobile displays, TV displays, and even flexible lighting panels. Despite commercial success, OLED is still an active area of research. In particular, many scientists are working to develop new materials that lower the cost of production and increase OLED efficiency.
