Abstract: This disclosure relates to reduced power consumption OLED displays at reduced cost for reduced information content applications, such as wearable displays. Image quality for wearable displays can be different than for high information content smart phone displays and TVs, where the wearable display has an architecture that in includes, for example, an all phosphorescent device and/or material system that may be fabricated at reduced cost. The reduced power consumption can facilitate wireless and solar charging.

Abstract: OLED device structures are provided that include an OLED, a high index optical layer (HOL), a thin film barrier disposed over the high index optical layer, and a low index optical layer (LOL) disposed over the thin film barrier. It is shown that such devices provide acceptable color emission that is at least comparable to a conventional device, while also exhibiting improved efficiency and luminance.

Abstract: Embodiments of the disclosed subject matter provide a wearable device that includes an organic light emitting diode (OLED) light source to output light having one peak wavelength from a single OLED emissive layer, and a first barrier layer that is disposed over or between the single OLED emissive layer and one or more down-conversion layers. One or more regions of the single OLED emissive layer are independently switchable and controllable so that the wearable device is configurable to output a plurality of wavelengths of light. One of the plurality of wavelengths of light that is output is near infrared light.

Abstract: Embodiments of the disclosed subject matter provide a full-color pixel arrangement for a device, the full-color pixel arrangement including a plurality of sub-pixels, each having an emissive region of a first color, where the full-color pixel arrangement comprises emissive regions having exactly one emissive color that is a red-shifted color of a deep blue sub-pixel of the plurality of sub-pixels. Embodiments of the disclosed subject matter may also provide a full-color pixel arrangement for a device, the full-color pixel arrangement including a plurality of sub-pixels, each having an emissive region of a first color, where the full-color pixel arrangement comprises emissive regions having exactly one emissive color, and where the plurality of sub-pixels comprise a light blue sub-pixel, a deep blue sub-pixel, a red sub-pixel, and a green sub-pixel.

Abstract: Devices, components and fabrication methods are provided for improving the efficiency of OLED displays. An outcoupling component such as a microlens array (MLA) is attached to an OLED, with a relatively small distance between the MLA and the OLED. Cross-talk and back scattering are reduced by the use of colored lenses, focusing layers, and other methods.
