Common cathode organic electroluminescent diode matrices, based on a new CN-derivative of poly(2,7-fluorene phenylidene) have been developed by photolithography. Optical characterization reveals their interesting properties as white-light emitters. In addition, 7times5 pixel alphanumeric display prototypes have been manufactured using a novel lithographic technique that saves processing steps and costs.
