Abstract: Methods and systems for organic vapor jet deposition are provided, where an exhaust is disposed between adjacent nozzles. The exhaust may reduce pressure buildup in the nozzles and between the nozzles and the substrate, leading to improved deposition profiles, resolution, and improved nozzle-to-nozzle uniformity. The exhaust may be in fluid communication with an ambient vacuum, or may be directly connected to a vacuum source.

Abstract: The present invention relates to efficient organic light emitting devices (OLEDs). The devices employ three emissive sub-elements, typically emitting red, green and blue, to sufficiently cover the visible spectrum. Thus, the devices may be white-emitting OLEDs, or WOLEDs. Each sub-element comprises at least one organic layer which is an emissive layer—i.e., the layer is capable of emitting light when a voltage is applied across the stacked device. The sub-elements are vertically stacked and are separated by charge generating layers. The charge-generating layers are layers that inject charge carriers into the adjacent layer(s) but do not have a direct external connection.

Abstract: A device is provided having a first electrode, a second electrode, a first photoactive region having a characteristic absorption wavelength λ1 and a second photoactive region having a characteristic absorption wavelength λ2. The photoactive regions are disposed between the first and second electrodes, and further positioned on the same side of a reflective layer, such that the first photoactive region is closer to the reflective layer than the second photoactive region. The materials comprising the photoactive regions may be selected such that λ1 is at least about 10% different from λ2. The device may further comprise an exciton blocking layer disposed adjacent to and in direct contact with the organic acceptor material of each photoactive region, wherein the LUMO of each exciton blocking layer other than that closest to the cathode is not more than about 0.3 eV greater than the LUMO of the acceptor material.

Abstract: An elastomeric stamp is used to deposit material on a non-planar substrate. A vacuum mold is used to deform the elastomeric stamp and pressure is applied to transfer material from the stamp to the substrate. By decreasing the vacuum applied by the vacuum mold, the elasticity of the stamp may be used to apply this pressure. Pressure also may be applied by applying a force to the substrate and/or the stamp. The use of an elastomeric stamp allows for patterned layers to be deposited on a non-planar substrate with reduced chance of damage to the patterned layer.
