Abstract: Methods and OLED devices are provided in which organic emissive materials are deposited over a substrate via OVJP print heads in a continuous line extending from one edge of the active display portion of a substrate to another. The print heads are arranged such that the sidewalls of the OVJP jet are disposed over non-emissive insulating portions of the display panel, thereby allowing for improved pixel density and resolution in comparison to conventional OVJP and similar techniques.

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: Designs and arrangements for sublimation cells are provided, which enriches an inert carrier gas with organic vapor such that the partial pressure of the organic vapor is highly stable in time. Stability is achieved by controlling the local rates of evaporation along the solid-gas interface through one or more crucibles, thereby reducing the effects of greater headspace and lowering interfacial area as the source depletes. Local evaporation rates also can be controlled using either temperature distribution or convective flow fields.

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.

Abstract: Embodiments of the disclosed subject matter provide methods and systems including a nozzle, a source of material to be deposited on a substrate in fluid communication with the nozzle, a delivery gas source in fluid communication with the source of material to be deposited with the nozzle, an exhaust channel disposed adjacent to the nozzle, a confinement gas source in fluid communication with the nozzle and the exhaust channel, and disposed adjacent to the exhaust channel, and an actuator to adjust a fly height separation between a deposition nozzle aperture of the nozzle and a deposition target. The adjustment of the fly height separation may stop and/or start the deposition of the material from the nozzle.

Abstract: A deposition device including an injection block and a print die is provided, which allows for vertical movement of the injection block while still maintaining connection between the print die and external gas sources. Also disclosed is an injection block suitable for such devices, which provides improved vertical range of motion and thermal consistency compared to conventional injection block devices.

Abstract: Techniques and devices are provided for attaching a die to a metal manifold. A metal-containing ink is used to deposit a metal trace on the die and thereby to form a gasket, after which the die is compressed against the manifold to form a sealed connection between the two.

Abstract: Embodiments of the disclosed subject matter provide a device that may have a first depositor that includes one or more delivery apertures surrounded by one or more exhaust apertures, where the one or more delivery apertures and the one or more exhaust apertures are enclosed within a perimeter of a boss that protrudes from a substrate-facing side of the one or more delivery apertures. The delivery channels for the one or more delivery apertures and exhaust channels for the one or more exhaust apertures may be routed orthogonally to each other. The one or more delivery apertures may be configured to permit jets of delivery gas pass through a lower surface of the first depositor. The lower surface of the first depositor may include the one or more exhaust apertures to remove surplus vapor from a delivery zone. Embodiments may also provide a method of forming a print head.

Abstract: Systems and techniques for deposition such as via OVJP using multiple source ampules are provided. The source ampules are arranged and controlled such that carrier gas may be fed through each source ampule sequentially, thereby allowing for more continuous operation and use of materials that otherwise would be subject to thermal degradation.
