Abstract:
The present disclosure provides a fingerprint photocurrent detection unit, a fingerprint identifier, a driving method and a display device. The fingerprint photocurrent detection unit includes: a conversion circuit coupled to a fingerprint photocurrent reading line and configured to convert a fingerprint photocurrent acquired by the fingerprint photocurrent reading line into a square wave signal; and a detection circuit coupled to the conversion circuit and configured to detect the square wave signal and acquire information about a fingerprint photocurrent in accordance with a frequency of the square wave signal.

Claim (Index 19):
The fingerprint identifier according to  claim 16 , wherein the detection control circuit comprises an edge trigger and a signal controller;\n an edge triggering end of the edge trigger is coupled to the output end of the phase inversion module, and an output end of the edge trigger is coupled to the first node; the edge trigger is configured to, in the case that the detection operation starts, control the potential at the third node to be the high level or low level, and in the case that the signal from the output end of the phase inversion circuit is at the rising edge or falling edge, control the potential at the first node to be the first level; and the signal controller is coupled to the first node, and configured to, in the case that the detection operation starts, control the potential at the first node to be the first level, and in the case that the potential at the first node is maintained as the first level for the predetermined time period, control the potential at the first node to jump to the second level.
