We have developed a novel method of patterning light emitting polymers using photolithography for the fabrication of full color polymer light emitting diode (PLED) displays. We have achieved this method by applying an insolubilization technique of PEDT/PSS to a conventional photolithography. Using this method, we fabricated PLEDs with a resolution of 200ppi, which is the highest resolution yet reported without a color filter.
