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.

Abstract: Devices and techniques are provided in which an OLED panel is operated in two modes. The first mode operates in a standard way to display an image or video or otherwise illuminate sub-pixels of the panel. In the second mode, some pixels are operated at a lower brightness than in the first mode. The use of multiple modes allows for improved sub-pixel lifetime and reduced sub-pixel and image degradation.

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: A transparent emissive device is provided. The device may include one or more OLEDs having an anode, a cathode, and an organic emissive layer disposed between the anode and the cathode. In some configurations, the OLEDs may be non-transparent. The device may also include one or more locally transparent regions, which, in combination with the non-transparent OLEDs, provides an overall device transparency of 5% or more.

Abstract: An image processing system includes an image sensor, an OLED display, a profile selection processor configured to select an output profile from among a plurality of pre-stored output profiles based at least in part on a digital representation of a target scene captured by the image sensor, and an image driver configured to drive the OLED display to display an image based on the selected output profile during a capture of an image of the target scene with the image sensor.

Abstract: A hybrid display includes a blue LED backlight layer, at least one shutter element, a frontplane having multiple sub-pixels, and a backplane operatively connected to the frontplane and the at least one shutter element. The backplane and the at least one shutter element are positioned between the backlight layer and the frontplane.
