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 7):
A method for driving the fingerprint photocurrent detection unit according to  claim 2 , comprising steps of:\n at a charging stage, controlling, by a detection control module, a potential at the first node to be a first level and a potential at a third node to be a high level or a low level, and controlling, by a first switching module, a high level line to be electrically coupled to a second node to charge a storage module and pull up a potential at the second node to the high level; and at a discharging stage, controlling, by the detection control module, the potential at the first node to jump to a second level, controlling, by the first switching module, the high level line to be electrically decoupled from the second node to enable a fingerprint photocurrent to flow from the second node, through a fingerprint photocurrent reading line and toward a reversely-biased photosensitive diode of a fingerprint touch unit and pull down the potential at the second node gradually until the second switching module is turned on, controlling, by a phase conversion module, the potential at the third node to jump to the low level or high level, controlling, by the detection control module, the potential at the first node to be reset as the first level, and acquiring, by a detection circuit, corresponding information about a fingerprint photocurrent in accordance with at least one of a frequency of a waveform of a potential at an output end of the phase inversion module and a frequency of a waveform of the potential at the first node.
