1. 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.
