    Abstract: 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.

    Abstract: A device having high index layers is provided. The device includes an organic light emissive device, an air interface, a first planarization layer, and a first barrier layer. The first planarization layer is disposed between the air interface and the organic light emissive device and has an index of refraction of at least 1.6. The first barrier layer is disposed between the first planarization layer and the organic emissive device and has an index of refraction of at least 1.6.

    Abstract: Embodiments of the disclosed subject matter provide a vapor distribution manifold that ejects organic vapor laden gas into a chamber and withdraws chamber gas, where vapor ejected from the manifold is incident on, and condenses onto, a deposition surface within the chamber that moves relative to one or more print heads in a direction orthogonal to a platen normal and a linear extent of the manifold. The volumetric flow of gas withdrawn by the manifold from the chamber may be greater than the volumetric flow of gas injected into the chamber by the manifold. The net outflow of gas from the chamber through the manifold may prevent organic vapor from diffusing beyond the extent of the gap between the manifold and deposition surface. The manifold may be configured so that long axes of delivery and exhaust apertures are perpendicular to a print direction.

    Abstract: Embodiments of the disclosed subject matter provide a micronozzle array including a linear array having a plurality of depositors connected in series, where a first depositor of the plurality of depositors may border a second depositor on a least one side boundary. The micronozzle array may include plurality of orifice arrays, where a width of each orifice in the plurality of orifice arrays is 20 μm or less in a minor axis of its cross section to flow, to regulate flow through a delivery gas distribution channel. The micronozzle array may include a plurality of exhaust distribution channels, where the delivery gas distribution channel and at least one of the plurality of exhaust distribution channels have separate fluid communication with each of the plurality of depositors.
