|1. (WO2018218999) FINGERPRINT RECOGNITION CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY PANEL|
|Applicants:||BOE TECHNOLOGY GROUP CO., LTD.
|Title:||FINGERPRINT RECOGNITION CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY PANEL|
The present disclosure provides a fingerprint recognition circuit, belonging to the field of display technologies, and being able to recognize human fingerprint information. A fingerprint recognition circuit of the present disclosure comprises a reset sub-circuit, a fingerprint sensing sub-circuit, a signal acquisition sub-circuit and a drive sub-circuit. The reset sub-circuit is connected to a read node, a reset port and a first port, and is used for resetting the potential of the read node. The fingerprint sensing sub-circuit is connected to the read node, and is used for acquiring fingerprint information, converting the fingerprint information into a detection signal and outputting same to the read node. The signal acquisition sub-circuit is connected to the read node, the drive sub-circuit and a power source port, and is used for outputting a signal of the read node to the drive sub-circuit. The drive sub-circuit is connected to a read port, the signal acquisition sub-circuit, an output port and a second port, and is used for outputting, by means of the read port, in a fingerprint recognition stage, a signal outputted by the signal acquisition sub-circuit, and for outputting, in a display stage, a signal of the read port to the output port.
