Abstract
An electronic device may have a display with a brightness that is adjusted based on ambient light data from multiple ambient light sensors. Sensors that are shadowed can be ignored. A touch sensor array in the display may have electrodes that overlap ambient light sensors. When a touch sensor signal indicates that an external object is covering one of the ambient light sensors, data from that ambient light sensor can be discarded. The ambient light sensors may include a primary ambient light sensor such as a human-eye-response ambient light sensor and may include an array of secondary ambient light sensors such as non-human-eye-response sensors. The secondary ambient light sensors may be formed on a display layer such as a thin-film-transistor layer and may be formed from thin-film materials. An algorithm may be used to dynamically calibrate non-human-eye-response ambient light sensors to the human-eye-response ambient light sensor.
