The photosensitive device comprises theabove photosensitive circuit. The electronic device comprises the photosensitive device.

Description

technical field [0001] The invention relates to a photosensitive circuit for sensing biometric information, a photosensitive device and electronic equipment. Background technique [0002] At present, fingerprint recognition has gradually become a standard component of electronic products such as mobile terminals. Since optical fingerprint recognition has stronger penetrating ability than capacitive fingerprint recognition, it is a future development trend for optical fingerprint recognition to be applied to mobile terminals. However, the existing optical fingerprint identification structure applied to mobile terminals still needs to be improved. Contents of the invention [0003] The embodiments of the present invention aim to solve at least one of the technical problems in the prior art. Therefore, the embodiment of the present invention needs to provide a photosensitive circuit, a photosensitive device and an electronic device. [0004] A photosensitive circuit accord...
