Abstract

An electronic device, a control method, a control module of the electronic device, and a computer-readable storage medium are provided. The electronic device includes: a shell; a display screen disposed in the shell; a fingerprint module movably disposed in an inner cavity; and a drive mechanism. The inner cavity is formed between the shell and the display screen. The drive mechanism is connected to the fingerprint module, and drives, in a case that the display screen is touched, the fingerprint module to move to a position corresponding to a first region. The first region is a region that is of the display screen and that is touched.

First claim

What is claimed is:

1. An electronic device, comprising:
a shell;
a display screen, wherein the display screen is disposed in the shell, and an inner cavity is formed between the shell and the display screen;
a fingerprint module movably suspended in the inner cavity; and
a drive mechanism connected to the fingerprint module and configured to drive, in response to the display screen being touched at a first region, the suspended fingerprint module by electrostatic force to move to a position corresponding to the first region in at least two directions.

2. The electronic device according to claim 1 ,
wherein:
the drive mechanism comprises a first conductive part and a second conductive part,
the first conductive part is disposed in the fingerprint module,
the second conductive part is disposed in the inner cavity, and
the first conductive part is disposed opposite the second conductive part, wherein the first conductive part comprises a first charged region, and the second conductive part comprises a second charged region and a third charged region,
wherein:
in a case that the display screen is touched, a first charge carried in the first charged region, a second charge carried in the second charged region, and a third charge carried in the third charged region drive the fingerprint module to be suspended in the inner cavity, and to move from a first position to a second position;
in a case that the fingerprint module is at the first position, the first charged region is disposed opposite the second charged region, a polarity of the first charge is the same as that of the second charge, and a polarity of at least part of the third charge is opposite to that of the first charge; or
in a case that the fingerprint module is at the second position, the first charged region is disposed opposite the third charged region, and a polarity of the first charge is the same as that of the third charge, wherein the second position is the position corresponding to the first region of the display screen.

3. The electronic device according to claim 2 ,
wherein:
the shell comprises a middle frame,
the display screen is connected to the middle frame,
the inner cavity is formed between the display screen and the middle frame,
the first conductive part is disposed on a surface, far away from the display screen, of the fingerprint module, and
the second conductive part is disposed on a surface, facing the fingerprint module, of the middle frame.

4. The electronic device according to claim 3 , further comprising:
a backlight module mounted on a side, facing the inner cavity, of the display screen, wherein the blacklight module comprises:
a light-enhancing part,
a diffusion part,
a light-guiding part, and
a reflection part that are sequentially disposed in a direction of the inner cavity.

5. The electronic device according to claim 4 , further comprising a rubber frame disposed in the inner cavity, wherein the reflection part is connected to the rubber frame using optical clear adhesive.

6. The electronic device according to claim 1 , further comprising a light-emitting component disposed in the shell, wherein the fingerprint module is an optical fingerprint module, and in a case that the display screen is touched, the light-emitting component emits light to the first region.

7. A control method, performed by an electronic device, comprising:
receiving an input on a display screen of the electronic device in response to the display screen being touched by a user at a first region, wherein the display screen is disposed in a shell, and an inner cavity is formed between the shell and the display screen;
obtaining a position on the display screen corresponding to the first region based on the input; and
controlling a drive mechanism to drive a fingerprint module suspended in the inner cavity to move to the position corresponding to the first region by electrostatic force in at least two directions.

8. The control method according to claim 7 , wherein obtaining the position on the display screen comprises:
receiving a tactile signal generated when the user touches the display screen; and
performing position recognition based on the tactile signal to obtain the position corresponding to the first region.

9. The control method according to claim 7 ,
wherein:
the drive mechanism comprises a first conductive part and a second conductive part,
the first conductive part is disposed in the fingerprint module,
