    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： Embodiments of the disclosed subject matter may provide a display device or display surface including at least one emissive layer and a near-infrared (NIR) emissive layer disposed in a stack arrangement between a first electrode and a second electrode, where NIR light is emitted from the NIR emissive layer through the at least one emissive layer, or visible light is emitted from the at least one emissive layer through the NIR emissive layer, and where the NIR light output by the NIR emissive layer has a peak wavelength of 740 nm-1000 nm. Embodiments of the disclosed subject matter may provide a near infrared (NIR) light source disposed behind or in front of an active-matrix organic light emitting diode (AMOLED), where the NIR light source has an area greater than 25% of an active area of the display device or display surface.

    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.
