A method of large-area dye diffusion for patterning the emissive color of organic light-emitting devices (OLEDs) using transferred photoresist is introduced. Using a large-area dye diffusion source, the dye is diffused into the emissive layer of the OLED. To locally pattern the emissive color, either a shadow mask or a patterned dye source has to be used. The implementation of both approaches using photolithographic patterning and transferred photoresist is outlined in this paper. In addition, a method using transferred photoresist for patterning of the cathode will be discussed.
