Abstract
An integrated proximity and light sensor includes an indicating light-emitting device ('ILD'), a projecting light-emitting device ('PLD'), and a light sensing integrated circuit (“LSIC”) configured as a single package. The LSIC controls each of the ILD and the PLD to emit light therefrom and the LSIC is configured to detect an ambient light level and also to detect a reflection of the light projected by the PLD from a surface for proximity detection.
