Abstract: An organic vapor jet printing (OVJP) device is provided that includes an OVJP print die having one or more delivery channels to deliver organic material and carrier gas to a region below the print die and one or more exhaust channels to remove material from below the print die. A directly-heated delivery line connected to the one or more delivery channels and a source of the organic material external to the OVJP print die includes a resistive material and a plurality of electrical connections to the resistive material. When a current is applied to the resistive material via the plurality of electrical connections, the resistive material heats the interior of the directly-heated delivery line.

Abstract: An organic vapor jet printing (OVJP) device is provided that includes an OVJP print head having a nozzle configured to eject an organic material entrained in a carrier gas, one or more heaters to heat the nozzle, and one or more heat sinks to remove heat from the region of the nozzle. OVJP deposition devices and techniques are also provided in which heat sinks are arranged in the region of one or more OVJP nozzle, which maintain an ambient temperature of not more than 40 C. when the print head is operated at an operating temperature of 450 C.

Abstract: Systems and methods for depositing materials on a substrate via OVJP are provided. A float table and grippers are used to move and position the substrate relative to one or more OVJP print bars to reduce the chance of damaging or compromising the substrate or prior depositions.

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.
