    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： 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.
