Abstract: Convolutional neural networks have, over the last decade, risen to state-of-the-art for computer vision tasks such as image classification. Oftentimes these are implemented on specialized digital processors, which target high throughput operation. This is efficient when analyzing batches of images loaded from memory but is lacking when analyzing freshly-captured images on a sensor. Latency is an issue since image acquisition alone can take as long as the processing. Second, streams of images captured from sensors can result in highly redundant processing if only specific signatures needs to be recognized, leading to a high amount of wasted power. Disclosed is a way to perform convolutional processing on the image plane where the image is captured, which allows the device to only complete readout and processing when required. This reduces latency and power consumption, enabling new applications such as augmented reality and edge processing that are not possible with current technology.

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.
