Electronic device

1. An electronic device, comprising:

a multi-functional power button, comprising:

a power switch; and

a fingerprint recognition module, combined on the power switch, the fingerprint recognition module is configured to extract a fingerprint feature information; and

a processor, electrically coupled to the multi-functional power button and configured to determine whether the multi-functional power button is pressed or touched to respectively cause the power switch to generate a switching signal or cause the fingerprint recognition module to extract the fingerprint feature information,

wherein the electronic device further comprises a shell combined with a limit piece to contain the multi-functional power button, the shell having an opening and an extension part, and the extension part extending from the opening toward the shell inside,

wherein the fingerprint recognition module comprises:

a fingerprint recognition sensor exposed on the opening of the shell;

a circuit board having a first surface and a second surface that are opposite to each other, wherein the fingerprint recognition sensor is disposed on the first surface, and the power switch is disposed on the second surface and located between the circuit board and the limit piece, wherein the power switch is in contact with the limit piece;

a metal electrode disposed on the second surface of the circuit board, wherein the power switch hoods the metal electrode and is electrically isolated from the metal electrode; and

a ladder part disposed on the first surface of the circuit board, and in contact with the extension part to define an upper limit of a movable range, wherein the ladder part is separable with the extension part, and

when the fingerprint recognition sensor is moved toward the limit piece, the power switch is deformed to contact with the metal electrode to generate the switching signal.

2. The electronic device of claim 1 , wherein when determining whether the multi-functional power button is pressed or touched, the processor determines whether an identity verification request is received in advance.

3. The electronic device of claim 1 ,

wherein the power switch is a metal dome switch.

4. The electronic device of claim 2 , further comprising:

a storage device, electrically coupled to the processor and configured to store at least one fingerprint recognition datum, wherein the processor compares the at least one fingerprint recognition datum and the fingerprint feature information;

when the at least one fingerprint recognition datum and the fingerprint feature information are matched, the processor generates a confirming signal to response the identity verification request.

5. The electronic device of claim 2 , further comprising:

a display device, electrically coupled to the processor, so that the processor executes an operation of power on or off of the display device according to the switching signal.

6. The electronic device of claim 5 , wherein when the display device is power on, the processor determines whether a duration of the switching signal is larger than a predetermined time;

when the duration is smaller than the predetermined time, the processor turns off the display device.

7. The electronic device of claim 5 , wherein when the display device is power off, the processor determines whether a duration of the switching signal is larger than a predetermined time;

when the duration is smaller than the predetermined time, the processor turns on the display device.

8. The electronic device of claim 5 , wherein the processor determines whether a duration of the switching signal is larger than a predetermined time;

when the duration is larger than the predetermined time, the processor executes a shutdown process.
