Abstract
A light source device and an electronic apparatus are provided. The light source device includes a substrate, an electrode layer and a surrounding frame disposed on the substrate, a light emitter and a light detector mounted on the electrode layer and located inside of the surrounding frame, and a light permeable member disposed on the surrounding frame and covering the light emitter and the light detector. When the light emitter receives a predetermined current so as to emit an invisible light toward the light permeable member, the light detector receives a reflected part of the invisible light to generate an initial photocurrent. When the light emitter receives a manipulation current so that a detection photocurrent generated from the light detector is less than a first proportion of the initial photocurrent or greater than a second proportion of the initial photocurrent, the light emitter stops receiving the manipulation current.
