Patent ID: 7897210

Claim:
A method of fabricating an organic device, the method comprising: depositing a first organic material over a substrate to form a first layer; ejecting an emissive second organic material from an apparatus having a nozzle, to form a plurality of physically-separate regions of the emissive second organic material over the first layer, while the nozzle is aligned with a source of the emissive second organic material so that the nozzle is in fluid communication with the source of the emissive second organic material; rotating the apparatus to align a source of an emissive third organic material with the nozzle to place the nozzle in fluid communication with the source of the emissive third organic material; ejecting the emissive third organic material from the nozzle, to form a plurality of physically-separate regions of the emissive third material over the first layer; and depositing a layer of a fourth organic material over each of the plurality of physically-separate regions of the emissive third organic material.
