Abstract
An electronic device includes a display screen, a first lens module, a fingerprint sensor, and a first driving mechanism. The first lens module, the fingerprint sensor, and the first driving mechanism are disposed close to a non-display surface of the display screen. The fingerprint sensor is configured to receive an optical signal transmitted through the display screen and the first lens module to collect fingerprint information. The first driving mechanism is configured to drive the first lens module to move, so as to change a fingerprint information collection area of the fingerprint sensor.
Claims19
An electronic device, comprising:
- a display screen comprising a display surface and a non-display surface opposite to each other;
- a first lens module;
- a fingerprint sensor configured to receive an optical signal transmitted through the non-display surface and the first lens module to collect fingerprint information;
- and
- a first driving mechanism connected to the first lens module and configured to drive the first lens module to move, so as to change a fingerprint information collection area of the fingerprint sensor, wherein the first lens module, the fingerprint sensor, and the first driving mechanism are disposed close to the non-display surface;
- and
- a processor connected to the first driving mechanism, wherein the processor is configured to control a movement of the first lens module to increase the fingerprint information collection area of the fingerprint sensor when the fingerprint sensor does not collect the fingerprint information or a matching degree between the fingerprint information collected by the fingerprint sensor and a preset fingerprint information is lower than a preset value.
A method for controlling an electronic device, wherein the electronic device comprises a display screen, a first lens module, a fingerprint sensor, and a first driving mechanism, the display screen comprises a display surface and a non-display surface opposite to each other, the first lens module, the fingerprint sensor, and the first driving mechanism are disposed close to the non-display surface, the first lens module is connected to the first driving mechanism, and the method for controlling the electronic device comprises:
- obtaining a detection result of the display screen;
- when the detection result comprises a pressing operation, controlling the fingerprint sensor to collect fingerprint information according to the pressing operation;
- determining whether the fingerprint sensor has collected the fingerprint information;
- and
- if the fingerprint sensor does not collect the fingerprint information, controlling the first lens module to move, so as to increase a fingerprint information collection area of the fingerprint sensor.
