Abstract
A proximity and light sensing device including a radiation emitter for proximity sensing positioned on a substrate. The device further includes a radiation detector positioned on the substrate, the radiation detector configured to detect radiation from the emitter. An ambient light detector is also positioned on the substrate and around the radiation emitter so as to form a border around the radiation emitter and detect off-axis ambient light rays.
