Stray-light-coupled biometrics sensing module and electronic apparatus using the same
First Claim
1. A stray-light-coupled biometrics sensing module, comprising:
- a light-transparent body having a front side and a backside, wherein the front side is configured to support an organic object thereon;
a display unit, which is attached to the backside of the light-transparent body and displays a frame;
an optical module, which is attached to the backside of the light-transparent body through an adhesive, and is disposed adjacent to the display unit, wherein;
first light rays of the frame couple into the organic object through the light-transparent body;
after travelling a short distance in the organic object, the first light rays couple out of the organic object and become second light rays, which enter the optical module through the light-transparent body;
the optical module senses the second light rays to generate a biometrics image signal; and
a control processing unit, which is electrically connected to the display unit and the optical module, and controls operations of the display unit and the optical module,wherein the control processing unit controls the display unit to display frames, and the optical module generates multiple image signals according to different wavelengths of the first light rays of the frames, respectively.

Abstract
A stray-light-coupled biometrics sensing module includes a light-transparent body, a display unit and an optical module. The light-transparent body has a front side and a backside. The front side is configured to support an organic object thereon. The display unit attached to the backside of the light-transparent body displays a frame. The optical module is attached to the backside of the light-transparent body through an adhesive, and is disposed adjacent to the display unit. First light rays of the frame emitted from an eye-viewing screen couple into the organic object through the light-transparent body. After travelling a short distance in the organic object, the first light rays couple out of the organic object and re-enter the light-transparent body as second light rays entering the optical module. The optical module senses the second light rays to generate a biometrics image signal. An electronic apparatus is also disclosed.
