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 16):
The fingerprint identifier according to  claim 15 , wherein the first switching module comprises a first switching transistor, a gate electrode of which is coupled to the detection control module and the first node, a first electrode of which is coupled to the high level line, and a second electrode of which is coupled to the second node;\n the second switching module comprises a second switching transistor, a, gate electrode of which is coupled to the fingerprint photocurrent reading line and the second node, a first electrode of which is coupled to the output end of the phase inversion module, and a second electrode of which is coupled to the input end of the phase inversion module; the storage module comprises a storage capacitor, a first end of which is coupled to the second node, and a second end of which is coupled to the low level line; the phase inversion module comprises A phase inverters coupled in series to each other, where A is an odd number and a positive integer; an output end of an a th  phase inverter is coupled to an input end of an (a+1) th  phase inverter, where a is an integer greater than or equal to 1 and smaller than A; and an input end of a first phase inverter is the input end of the phase inversion module, and an output end of an A th  phase inverter is the output end of the phase inversion module.
