  • ORGANIC VAPOR JET PRINTING SYSTEM
    Publication number: 20230357918
    Abstract: Methods, systems, and devices are provided for organic vapor jet deposition (OVJP), which require significantly fewer print heads than conventional OVJP deposition systems. The disclosed OVJP systems include half the number of OVJP print heads than a conventional system, or less, and provide for relative movement of the substrate and print heads to allow for rapid and comprehensive material deposition over the full surface of the substrate.
