Abstract

The fingerprint acquisition method provided by the embodiment of the invention comprises the following steps: acquiring a pressed region of a display screen; determining an overlapping region of the pressing region and a fingerprint identification area of the display screen; and under the condition that the area ratio of the overlapping region to the fingerprint identification region is greater than a threshold value, controlling the overlapping region to be displayed at a first brightness, so that a fingerprint sensor located below the display screen collects a fingerprint in the overlappingregion. According to the fingerprint acquisition method provided by the embodiment of the invention, under the condition that the area ratio of the overlapping region to the fingerprint identificationregion is greater than the threshold, the overlapping region is controlled to emit light at the first brightness, so that a fingerprint sensor can acquire the fingerprint image for fingerprint identification; in addition, the light of the intersection region can be shielded to prevent the light of the intersection region from directly irradiating into human eyes, so that stimulation of the lightto human eyes is reduced, and user experience is improved.
