Abstract:
A selective organic emissive material deposition technique is disclosed. A charged organic emissive material may be mixed with a carrier gas and ejected towards a charged intended area of a substrate. The charge for the emissive material may be such that the organic emissive material is attracted to the charged intended area of the substrate and, accordingly, deposited selectively over the charged intended area of the substrate. Additionally, surrounding unintended areas of the substrate may be charged such that the charged organic emissive material is repelled by the unintended areas.
