Fingerprint detection module, electronic device, detection method and apparatus, and storage medium
摘要:
The fingerprint detection module having at least one fingerprint identification component and an acquisition component. The fingerprint identification component includes a reset unit, a photosensitive unit, and a follower unit. The reset unit switches a voltage at an output end of the photosensitive unit to an initial voltage according to a reset signal. The photosensitive unit receives reflected light of a to-be-detected fingerprint and accumulates charges, outputs a first electrical signal according to a received pulse control signal at a first level, and outputs a second electrical signal according to a next received pulse control signal at the first level. The follower unit receives the first electrical signal and forms a first voltage, and receives the second electrical signal and forms a second voltage. Further, the acquisition component receives the first voltage and the second voltage, and acquires the fingerprint according to a difference between the second and first voltage.
