The electronic transport and optoelectronic properties of crystalline and amorphous phases of nconjugated organic molecular films have been extensively investigated over the past decade. This vast body of research has led to remarkable advances in applications of these materials to optoelectronic devices, e.g. organic light emitting diodes (OLED) and photovoltaic cells, and electronic devices, e.g. organic field effect transistors. Commercialization of organic-based devices has begun in Japan and the US. Single OLEDs and small color displays are being manufactured and integrated in a number of consumer products. Prototypes of medium and large scale high-resolution full-color displays have been demonstrated. Direct printing and new lithographic techniques for large scale organic-based electronics on flexible substrates are being developed.
