Abstract
Systems and methods for an ambient light sensor (ALS) disposed under a display layer. In some implementations, an ALS reading is adjusted by compensating for light leakage in a display environment. In some aspects, a display leakage component may be determined based on image content driven onto a display pixel array during the ALS reading. An ambient light measurement may be generated by subtracting the display leakage component from the ALS reading and then adjusting a display brightness of the display pixel array in response to the ambient light measurement.
