Electronic Device With Directional Ambient Light Sensor

摘要

An electronic device may be provided with a display mounted in a housing. A directional ambient light sensor may measure the intensity and direction of ambient light. The ambient light sensor may be mounted in alignment with a light sensor window formed in an inactive area of the display. The ambient light sensor may be formed from detectors on a semiconductor substrate. Incident light angle restriction structures may define openings for each detector. Each opening may be configured to allow light with a different range of angle of incidence values to be passed to a respective one of the detectors. The ranges of acceptance angle for adjacent detectors may overlap. A sensor may produce a diffuse light reading by processing ambient light data from a diffuse light detector and a directional light detector. The diffuse and directional light detectors may be formed on a common semiconductor substrate.

1. An electronic device that is exposed to ambient light characterized by a range of angles of incidence, comprising:
a housing; control circuitry in the housing; and a directional ambient light sensor in the housing with which the control circuitry measures an ambient light intensity versus angle of incidence profile for the ambient light, wherein the directional ambient light sensor comprises a plurality of light detectors with partially overlapping angle of incidence sensitivity profiles.
