Organic Smart Pixels and Complementary Inverter Circuits Formed on Plastic Substrates by Casting, Printing and Molding

This letter describes the characteristics of two types of organic electronic devices - monolithically integrated transistors and light emitting diodes (e.g., smart pixels), and complementary inverter circuits - that are supported by flexible plastic substrates and fabricated with low cost casting, printing and molding techniques. The organic smart pixels are the first such devices formed on plastic substrates, and the inverters represent the first printed circuits that incorporate multiple transistors with micron-sized features. Both devices have geometries and performance comparable to similar components produced with conventional photolithographic techniques on rigid, inorganic supports.
