Abstract
Described herein are light sensors that primarily respond to visible light while suppressing infrared light. Also described herein are systems the incorporate such light sensors. Such a system can include a display, a light source to backlight the display and a controller to control the brightness of the light source based on feedback received from such light sensors. Described herein are also methods for controlling backlighting.
