IMAGE SENSING APPARATUS FOR FINGERPRINT IDENTIFICATION AND RELATED DECODER CIRCUIT

摘要

An image sensing apparatus includes a substrate, a light guide plate, a plurality of photosensors and a light source. The substrate has a first side. The light guide plate has a light exit surface and a light entry surface, wherein the light exit surface faces the first side of the substrate. The photosensors are disposed on the first side of the substrate. The light source is disposed near the light entry surface of the light guide plate, wherein light generated from the light source enters the light guide plate through the light entry surface. After entering the light guide plate, the light generated from the light source is incident to the substrate through the light exit surface of the light guide plate, or travels in the light guide plate by total internal reflection.
