摘要： Organic electroluminescent devices are provided, including devices having a tandem structure in which two or more plasmonic OLEDs are arranged in a stack. The plasmonic OLEDs may be inverted or non-inverted. A common electrode disposed between the OLEDs or an outer electrode of the device provides the enhancement layer for one or plasmonic OLEDs in the stack.

摘要： 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.

摘要： Devices and techniques are provided for depositing material on a substrate, such as for fabrication of OLEDs and layers used in OLEDs. A depositor block includes one or more delivery apertures, one or more exhaust apertures, and one or more confinement gas channels. Each delivery aperture is arranged such that it is between an exhaust aperture and a confinement gas channel, thereby improving deposition by reducing overspray of material.

摘要： 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.

摘要： Embodiments of the disclosed subject matter provide a depositor device having a first exhaust aperture and a second exhaust aperture, and a plurality of delivery apertures disposed between the first exhaust aperture and the second exhaust aperture. A first aperture of the plurality of delivery apertures may have a first length, and a second aperture of the plurality of delivery apertures may have a second length. The first length may be longer than the second length. The device may include a third aperture of the plurality of delivery apertures which may have a third length, where the second length may be longer that the third length. The plurality of delivery apertures of the device may include three or more delivery apertures having different lengths.

摘要： Organic vapor jet printing (OVJP) devices and techniques are provided that use a solid materials sublimation source to provide material for deposition on a substrate. Carrier gas from a carrier gas source entrains vapor from the solid material within each sublimation source for transport to a print head within a deposition chamber. The sublimation source includes a sufficiently long internal flow path to achieve an acceptable level of material saturation of the carrier gas.

摘要： OVJP depositors having an exhaust aperture incorporated into the center of a flow retarder (510) 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.
