发明名称 Selective OLED vapor deposition using electric charges
摘要 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.

主权项 1. A method comprising: applying a first electric charge having a magnitude of at least 5V to at least a portion of a first mixture, the first mixture comprising a first organic emissive material and a first carrier gas; applying a second electric charge having a magnitude of at least 5V to a first portion of a substrate, the second electrical charge being of opposite sign to the first electric charge; and directing the first organic emissive material toward the substrate.
