The physics and chemistry of conducting polymers have matured to the point where these novel materials are ready for use in a variety of electronic applications. High performance devices have been demonstrated, including light emitting diodes, light emitting electrochemical cells, photodiodes and lasers. Performance parameters have been improved to levels comparable to or better than their inorganic counterparts. A brief review will be given with emphasis on progress toward the commercialization of polymer emissive displays and image sensors based upon polymer photodiode arrays.
