    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.

    Abstract: A hybrid pixel arrangement for a full-color display is provided, which includes an inorganic LED in at least one sub-pixel, and an organic emissive stack in at least one other sub-pixel. In an embodiment, a first sub-pixel is configured to emit a first color, and includes an inorganic LED, a second sub-pixel is configured to emit a second color, and includes a first portion of a first organic emissive stack configured to emit an initial color different from the first color. A third sub-pixel is configured to emit a third color different from the initial color, and includes a second portion of the first organic emissive stack, and a first color altering layer disposed in a stack with the second portion of the first organic emissive stack.

    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 translation: 本公开涉及降低功耗OLED显示器，以降低成本，减少信息内容应用，例如可穿戴显示器。 可戴式显示器的图像质量可以与用于高信息内容的智能手机显示器和电视机不同，其中可穿戴式显示器具有包括例如可以以较低成本制造的全磷光装置和/或材料系统的架构。 降低的功耗可以促进无线和太阳能充电。
