Abstract: Novel phosphorescent tetradentate platinum compounds of Formula I are provided. The complexes contain a dibenzo moiety, which allows for the creation of OLED devices with improved properties when compounds of Formula I are incorporated into such devices. Compounds of Formula I′ that comprise two ligands that contain a 5-membered carbocyclic or heterocyclic ring, one of which contains an imidazole ring with a twisted aryl group attached to N−1 and a second aromatic ring that is attached to the platinum via a carbon atom. These compounds may be advantageously used in OLEDs.

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: 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: 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.

Abstract: OVJP print bars are provided that include multiple print head segments, each of which includes a print head and which can be positioned relative to the substrate independently of each other print head segment. Accordingly, a more consistent head-to-substrate distance can be maintained even for substrates that are not uniformly planar.

Abstract: Systems and techniques for depositing organic material on a substrate are provided, in which one or more shield gas flows prevents contamination of the substrate by the chamber ambient. Thus, multiple layers of the same or different materials may be deposited in a single deposition chamber, without the need for movement between different deposition chambers, and with reduced chance of cross-contamination between layers.
