Devices for deposition of material via organic vapor jet printing (OVJP) and similar techniques are provided. The depositor includes delivery channels ending in delivery apertures, where the delivery channels are flared as they approach the delivery apertures, and/or have a trapezoidal shape. The depositors are suitable for fabricating OLEDs and OLED components and similar devices.

Organic vapor jet printing system

OVJP depositors having an exhaust aperture incorporated into the center of a flow retarder () are provided. Multiple flow retarders may be used to increase uniformity for applications such as OLED lighting that require larger features. Flow retarders may transect a delivery aperture completely or may extend part way through its length.

OVJP deposition nozzle with delivery flow retarders

Novel phosphorescent heteroleptic iridium complexes with phenylpyridine and dibenzo-containing ligands are provided. Alkyl substitution at specific positions on the ligands gives rise to compounds with improved OLED properties, including saturated green emission.

Heteroleptic iridium complexes as dopants

A deposition nozzle is provided that includes offset deposition apertures disposed between exhaust apertures on either side of the deposition apertures. The provided nozzle arrangements allow for deposition of material with a deposition profile suitable for use in devices such as OLEDs.

Organic electroluminescent devices

Embodiments of the disclosed subject matter provide an apparatus having a device with a micronozzle array disposed on a micro-fabricated fluidic die. The device may include a first gas distribution plate and a second opposing plate, where the micro-fabricated fluidic die is disposed between the first gas distribution plate and the second opposing plate, wherein the first gas distribution plate is irreversibly joined to the micronozzle array with a seal that is gas-tight, and where the first gas distribution plate includes a plurality of sealed flow paths. A manifold may be reversibly joined to the first gas distribution plate, where the micro-fabricated fluidic die and the first gas distribution plate and the second opposing plate are disposed between the manifold. A thermally conductive plate may have at least one window that provides a clearance fit for the device across a range of motion relative to the thermally conductive plate.

Embodiments of the disclosed subject matter provide a device including a micronozzle array having separate redundant groups of depositors that each include a delivery aperture disposed between two exhaust apertures. The device may include a first row of depositors of a first redundant group, each of which may be connected in parallel to first common delivery lines and first common exhaust lines. The device may include a second row of depositors of a second redundant group, each of which is connected in parallel to second common delivery and second common exhaust lines. The first row of depositors and the second row of depositors may operate independently from one another. The device may be disposed within a deposition chamber and in proximity of a substrate.

Apparatus and method to deliver organic material via organic vapor jet printing (OVJP)

Embodiments of the disclosed subject matter provide a device having a substrate, and a plurality of unit areas of an organic light emitting diode (OLED) display disposed on the substrate. The unit areas may be repeating, area-filling subdivisions on the substrate that each have an anode and a cathode. The organic film may be disposed over portions of the device other than the unit areas. The device may include at least one pixel having a plurality of sub-pixels disposed within each of the plurality of unit areas. The cathode of at least one pixel of each of the plurality of unit areas may be a common cathode.

OLED display with all organic thin film layers patterned

Nozzle exit contours for pattern composition

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.

A composition of materials including a first compound having a structure according to Formula I

Organic electroluminescent materials and devices

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.

Pixel configurations for high resolution OVJP printed OLED displays

This invention discloses metal complexes containing a ligand comprising a carborane moiety. Organic electroluminescent devices comprising these metal complexes containing a carborane moiety in the light-emitting layer showed desired properties in term of external quantum efficiency (EQE), device lifetime (LT), and color purity as measured by CIE.

Embodiments of the disclosed subject matter provide a device having a print head that includes a micronozzle array of depositors to deposit a material on a substrate. A reflective optical device may reflect a signal output by at least one optical sensor, and to reflect the signal from a surface of the substrate to the optical sensor. A processor may determine a distance between the optical sensor and the target surface of the substrate. The device may include one or more actuators coupled to the at least one print head to move the print head relative to an internal reference frame and adjust a position of the print head to the substrate. The sensor may be fixedly coupled with a mount to the internal reference frame. The print head may be configured to move independently of the optical sensor in at least one axis of linear or rotational motion.
