Ambient light detector, detector array and method

Abstract

An ambient light detector, a detector array and a method are disclosed. An ambient light sensor includes a first plurality of sensor elements, where each sensor element is configured to provide a signal in response to a level of illumination and a second plurality of reference elements, each reference element configured to provide a reference signal and each including a blocking element configured to shield the respective reference element from being illuminated, where the first plurality is larger than the second plurality and the first plurality of sensor elements and the second plurality of reference elements are arranged in an array, and where a sensor element and a reference element are laterally arranged on or in a common layer substrate sharing at least one common first contact.

Dependencies are inferred from the claim text.
