Abstract:
Provided is a fingerprint recognition circuit, including a resetting sub-circuit, a fingerprint sensing sub-circuit, a signal acquiring sub-circuit, and a driving sub-circuit, the resetting sub-circuit is connected to the reading node, the resetting port, a first port for resetting the reading node; the fingerprint sensing sub-circuit is connected to the reading node for acquiring fingerprint information, converting it into a detection signal to output to the reading node; the signal acquiring sub-circuit is connected to the reading node, the driving sub-circuit and a power port to output a signal of the reading node to the driving sub-circuit; the driving sub-circuit is connected to a reading port, the signal acquiring sub-circuit, an output port and a second port, outputs the signal output by the signal acquiring sub-circuit through the reading port in a fingerprint recognition stage, outputs the signal of the reading port to the output port in a display stage.
