摘要： Embodiments of the present invention are directed to light sensors, that primarily respond to visible light while suppressing infrared light. Such sensors are especially useful as ambient light sensors because such sensors can be used to provide a spectral response similar to that of a human eye. Embodiments of the present invention are also directed to methods of providing such light sensors, and methods for using such light sensors.

摘要： A photodetector includes one or more first photodiode regions that are covered by an optical filter configured to reject infrared (IR) light and that produce a first current (I1). The photodetector also includes one or more second photodiode regions that are covered by a light blocking material configured to reject visible and infrared light and that produce a second current (I2). The photodetector also includes one or more third photodiode regions that are not covered by the optical filter and are not covered by the light blocking material and that produce a third current (I3). Additionally, the photodetector includes circuitry configured to produce an output indicative of the first current (I1) or a scaled version of the first current (I1), minus the second current (I2) or a scaled version of the second current (I2), minus the third current (I3) or a scaled version of the third current (I3). The optical filter configured to reject IR light can be, e.g., a dielectric reflective optical coating filter, an IR absorption optical coating filter, or a combination thereof.
