摘要： 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.

摘要： 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.

摘要： Luminaires and luminaire components are provided that may include emissive, index-matching, and/or outcoupling components that are replaceable separately from other components of the luminaire. In some embodiments, an index-matching component may include a gel sheet or pad that can be disposed between an emissive component and an outcoupling component. The index-matching component may be replaceable separately from the emissive and outcoupling components. In some embodiments, an emissive component including an OLED panel and/or an index-matching component may be replaceable separately from other components of the luminaire.

摘要： OLED structures including an internal extraction layer are provided. The internal extraction layer includes a material having a refractive index that is higher than the refractive index of a transparent electrode in the device, and a non-planar interface disposed between the material and the substrate. Devices are also provided that include an external extraction layer having a non-planar surface which, when used in conjunction with an internal extraction layer, provides greatly improved outcoupling of light generated by the device.

摘要： Devices and components are provided that include a curved outcoupling component and an OLED, where the outcoupling component provides up to 100% outcoupling of light emitted by the OLED into air. The outcoupling component has an outer radius R and includes a material with a refractive index n. The OLED is in optical communication with the outcoupling component and disposed such that each emissive element of the OLED is within a distance r measured from the center of curvature of the surface at the outer radius R, such that R−r>(n−1)r.

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 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.
