Abstract: Devices and techniques are provided in which a transparent substrate is scored to provide a non-planar surface on one side of the substrate. An OLED is then disposed on the other side of the scored substrate and optically coupled to the substrate. The scored surface provides improvements to outcoupling of light generated by the OLED, with little or no additional thickness relative to the OLED alone.

Abstract: Embodiments disclosed herein provide devices having a nozzle die with one or more nozzles, each of which has one or more integrated skimmers. The use of an integrated nozzle/skimmer structure allows for higher-resolution printing in OVJP-type deposition techniques without requiring the use of a shadow mask by allowing for a relatively narrow organic material beam that can be placed at relatively high distances away from the 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: Optical components and devices are provided that include a substrate, a microlens array, and a barrier film system conformally covering the microlens array. An OLED may be optically coupled to the microlens array. The barrier film may provide protection to the microlens array or other components, without having a significant negative impact on outcoupling of light from the coupled OLED by the microlens array.
