Abstract: Embodiments may provide an extendable light source with a variable light emitting area. A first device is provided that includes a support, a first substrate movably coupled to the support, and a plurality of lighting devices disposed on the first substrate. The plurality of lighting devices includes a first portion of lighting devices and a second portion of lighting devices. The first device also includes an energizing component that is configured to selectively energize the first portion and the second portion of lighting devices based on a position of the first substrate relative to the support.

Abstract: Methods of fabricating a device having laterally patterned first and second sub-devices, such as subpixels of an OLED, are provided. Exemplary methods may include depositing via organic vapor jet printing (OVJP) a first organic layer of the first sub-device and a first organic layer of the second sub-device. The first organic layer of the first sub-device and the first organic layer of the second sub-device are both the same type of layer, but have different thicknesses. The type of layer is selected from an ETL, an HTL, an HIL, a spacer and a capping layer.

Abstract: Systems and methods are provided for depositing thin patterned films of materials in which individual elements of the patterned film are deposited by two or more nozzles having different geometries. The different nozzle geometries may include one or more of different throttle diameters, different exhaust diameters, different cross-sectional shapes, different bore angles, different wall angles, different exhaust distances from the substrate, and different leading edges relative to the direction of movement of the nozzles or the substrate. Methods may include steps of ejecting a carrier gas and a material from a plurality of nozzles and depositing the material on a substrate in a plurality of laterally spaced elements.

Abstract: An emissive layer deposited in graded manner using a plurality of nozzles is disclosed. A mixtures ejected from the plurality of nozzles may contain varying concentrations of host-to-dopant material. The nozzles, as disclosed, may be arranged in a sequential manner such that the order of the sequence is based on varying concentration of the host-to-dopant material. The nozzles may be configured to translate relative to an area of a substrate to allow sequential deposition.
