Abstract

An electronic device and a physiological characteristic identifying module are provided. The electronic device includes a case, a physiological characteristic identifying element, a cover plate, a key cap, and an insulating static electricity shielding ring. The case has a first hole. The physiological characteristic identifying element is disposed in the first hole. The cover plate is disposed on the case and has a second hole. At least a portion of an upper surface of the physiological characteristic identifying element is exposed by the second hole. The key cap is disposed in the second hole and located above the upper surface. The insulating static electricity shielding ring is disposed on the rim of the physiological characteristic identifying element and covers an outer portion of the upper surface and at least a portion of a lateral surface of the physiological characteristic identifying element.

First claim

What is claimed is:

1. A physiological characteristic identifying module disposed in an electronic device, the physiological characteristic identifying module comprising:
a physiological characteristic identifying element disposed in a first hole of a case of the electronic device;
a key cap disposed in a second hole of a cover plate of the electronic device and located above an upper surface of the physiological characteristic identifying element, wherein the second hole exposes at least a portion of the upper surface; and
an insulating static electricity shielding ring disposed on a rim of the physiological characteristic identifying element and covering an outer portion of the upper surface and at least a portion of a lateral surface of the physiological characteristic identifying element, wherein the lateral surface and the upper surface are located on different planes, and
wherein an orthographic projection of a gap between the key cap and a hole wall of the second hole on the upper surface completely avoids an area of the upper surface that is not covered by the insulating static electricity shielding ring.

2. The physiological characteristic identifying module according to claim 1 , wherein a resistance value of the insulating static electricity shielding ring is greater than 10 9 Ω.

3. The physiological characteristic identifying module according to claim 1 , further comprising a waterproof glue applied between the lateral surface and a hole wall of the first hole and between the insulating static electricity shielding ring and the hole wall of the first hole.

4. The physiological characteristic identifying module according to claim 1 , wherein the physiological characteristic identifying element is a fingerprint identifying element.

5. The physiological characteristic identifying module according to claim 4 , wherein the fingerprint identifying element is a capacitive fingerprint identifying element.
