We have developed an approach to fabricate pixelated organic polymer light-emitting devices (OPLED) using an imprinting technique. The pixel array pattern was first defined in an insulating polymer layer on indium tin oxide glass by direct imprinting, followed by the spin-coating of OPLED polymers and cathode metal deposition. We demonstrated successful fabrication and operation of OPLED pixels of sizes from 50 mum down to 2 mum. Optoelectronic characterization is performed on these devices, and measured results show comparable device performance with OPLED pixels patterned by other methods. This fabrication scheme holds many merits such as easy to process, low-cost, high yield, expandable to flexible substrate, capable of repeated imprinting for large area arrays, and the potential to pattern submicron and nanoscale, organic polymer light emitters.
