Abstract
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.
