    Abstract: Embodiments of the disclosed subject matter provide a device having an organic light emitting device (OLED) display comprising a plurality of metapixels. Each metapixel of the plurality of metapixels may have two or more sets of emissive regions that are configured to: (i) emit blue light that is a combination of light from the two or more sets of emissive regions that are configured to emit the blue light for that metapixel, and/or (ii) that are addressable by the same drive circuit. The metapixel may include more than one independently addressable sub-pixel configured to emit green light and more than one independently addressable sub-pixel configured to emit red light.

    Abstract: Embodiments of the disclosed subject matter provide a device that includes an organic light emitting device (OLED), and a drive circuit to control the operation of the OLED, comprising a response time accelerator thin film transistor (TFT) configured to short or reverse bias the OLED for a predetermined period of time during a frame time. Other embodiments include an OLED having a plurality of sub-pixels, where one or more of sub-pixels configured to emit light of at least a first color comprises a first emissive area and a second emissive area that are independently controllable, where the first emissive area is larger than the second emissive area. The controller is configured to control the second emissive area to have (i) a higher brightness, and/or (ii) a higher current density than the first emissive area for a first sub-pixel luminance level that is less than a maximum luminance.

    Abstract: Embodiments of the disclosed subject matter provide a display including a plurality of emissive surfaces, where each of the plurality of emissive surfaces has emissive devices that are deposited or attached in the same plane, with each of the plurality of emissive surfaces configured with independent scan and data drivers. The display may be configured to display an image that is a combination of light from the plurality of emissive surfaces, wherein each of the plurality of emissive surfaces renders an image that differs by at least one selected from the group consisting of: color resolution, fill-factor, viewing angle, and transparency. Embodiments also provide an augmented reality (AR), virtual reality (VR), or mixed reality (MR) system having a plurality of displays that each rendering an image based on the provided light of a different color spectrum, and one or more waveguides through which the light from the displays is combined.

    Abstract: A hybrid neuromorphic computing device is provided, in which artificial neurons include light-emitting devices that provide weighted sums of inputs as light output. The output is detected by a photodetector and converted to an electrical output. Each neuron may receive output from one or more other neurons as initial input, allowing for high degrees of fan-out and fan-in, including true broadcast-to-all functionality.
