Method of fabricating and patterning oleds

摘要

A patterning system (22) with a photoresist overhang (24a) allows material to be deposited onto a substrate (20) in various positions by varying the angle from which the material is deposited, and by rotating the substrate. The patterning system can be used to fabricate a stack of organic light emitting devices on a substrate using the same patterning system and without removing the substrate from vacuum.
