    Abstract: Embodiments of the disclosed subject matter provide a device including an organic light emitting device (OLED) display having at least one pixel having a plurality of sub-pixels, where at least one color sub-pixel of the plurality of sub-pixels may be configured to output red light, green light, and/or blue light. The device may include at least one sub-pixel that is configured to have a Lambertian emission, and at least one sub-pixel having a microcavity configured for direct emission such that a first ratio of light from the direct emission sub-pixel in a cone having an angle of 0-20° in a normal direction relative to an overall light emission from the direct emission sub-pixel having at least 10%, at least 20%, and/or at least 30% higher than a second ratio of light from the Lambertian emission sub-pixel.

    IPC: H01L27/32

    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.

    IPC: H01L51/50

    Abstract: Embodiments of the disclosed subject matter provide a device having a substrate, at least one organic light-emitting layer disposed over the substrate, and at least one down-conversion layer. The at least one down-conversion layer may generate the NIR emission by absorbing at least a portion of the light emitted by the at least one organic light emitting layer, and re-emitting light at a longer NIR wavelength or range of wavelengths having a peak NIR emission that may be greater than 700 nm, greater than 750 nm, or greater than 800 nm. An out-of-plane optical density of the at least one down-conversion layer may be less than 0.1 for all wavelengths of light in a range from 400 nm to 600 nm.
