Abstract

The invention discloses a photosensitive driving circuit, a photosensitive device and electronic equipment. The photosensitive driving circuit is used for driving all photosensitive pixels in the photosensitive device to execute light sensing simultaneously and controlling all the photosensitive pixels to end execution of light sensing after the photosensitive pixels start execution of light sensing so as to latch electric signals generated when the photosensitive pixels execute light sensing; and after all the photosensitive pixels end execution of light sensing, the latched electric signalscorresponding to the photosensitive pixels are sequentially controlled to be output.

Description

technical field [0001] The invention relates to a light-sensing driving circuit, a light-sensing device and electronic equipment for sensing biometric information. 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 driving circuit, a photosensitive device and an electronic device. [0004] A photosensitive ...
