FINGERPRINT IDENTIFICATION APPARATUS
First Claim
1. A fingerprint identification apparatus configured to sense a fingerprint, the fingerprint identification apparatus comprising:
- a display device having a plurality of pixel regions and a plurality of transmissive regions located between the pixel regions;
a first translucent base having a plurality of photosensitive regions and a plurality of light-emitting regions located between the photosensitive regions;
a plurality of photosensitive structures respectively disposed in the photosensitive regions of the first translucent base;
a first light-guide structure, wherein the first translucent base is disposed between the photosensitive structures and the first light-guide structure; and
a light source disposed adjacent to the first translucent base and configured to emit a light beam, wherein the light beam is, in order, guided by the first light-guide structure to be transmitted from one of the light-emitting regions of the first translucent base toward the display device, passes through one of the transmissive regions of the display device, is diffused by the fingerprint, and passes through another of the transmissive regions of the display device to be transmitted to one of the photosensitive structures.

Abstract
A fingerprint identification apparatus including a display device, a first translucent base, photosensitive structures, a first light-guide structure, and a light source is provided. The display device has pixel regions and transmissive regions located between the pixel regions. The first translucent base has photosensitive regions and light-emitting regions located between the photosensitive regions. The photosensitive structures are respectively disposed in the photosensitive regions of the first translucent base. The first translucent base is disposed between the photosensitive structures and the first light-guide structure. The light source is disposed adjacent to the first translucent base.
