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