Abstract
This disclosure provides systems, methods and apparatus for measuring the direction distribution of light. In some implementations, an ambient light direction distribution sensor device can include, for example, a light steering layer that is designed to steer light from different incident angles toward associated locations on a light detector. The light detector can then output one or more signals that are indicative of the amount of light that is incident upon the sensor device from different incident angles. These measurements can be used to control various parameters of a display in response to the detected ambient lighting conditions.
