Abstract

See full text

Devices, systems, and techniques are provided for improved OVJP deposition using a shutter disposed within the OVJP print head, between the print head inlet and the nozzle outlets. An OVJP print head as disclosed includes an inlet for organic material entrained in a carrier gas, a micronozzle array outlet, and a shutter disposed in the gas flow path between the inlet and the micronozzle array outlet. The shutter allows for rapid cutoff of carrier gas flow through the print head with extremely low latency.
