Display device and driving same


In a pixel circuit, during a period during which an organic el element is not emitting light, a transistor is in an “on” state and a reverse-direction voltage determined by a reverse-direction current that depends on the degree to which degradation of the organic el element has progressed is written to a capacitor. The transistor then turns off, another transistor turns on, and a compensating current that depends on the reverse-direction voltage flows from another capacitor towards a reverse-biasing power-supply line, causing a drive voltage maintained by the capacitor to change by a compensating voltage change.

Navigation based on radar-cued visual imaging


A navigation system for a vehicle may include at least one image capture device configured to acquire a plurality of images of an environment of a vehicle and a radar sensor to detect an object in the environment of the vehicle and to provide and output including range information indicative of at least one of a range or range rate between the vehicle and the object. The system may also include at least one processing device programmed to: receive the plurality of images from the at least one image capture device; receive the output from the radar sensor; determine, for each of a plurality of image segments in a first image, from among the plurality of images, and corresponding image segments in a second image, from among the plurality of images, an indicator of optical flow; use range information determined based on the output of the radar sensor together with the indicators of optical flow determined for each of the plurality of image segments in the first image and the corresponding image segments in the second image to calculate for each of a plurality of imaged regions at least one value indicative of a focus of expansion; identify a target object region, including at least a subset of the plurality of imaged regions that share a substantially similar focus of expansion; and cause a system response based on the identified target object region..
