摘要： Sensing circuit, detection control method, fingerprint identification module and display apparatus are provided. The sensing circuit comprises a photoelectric conversion element, an energy storage circuit, a switch control circuit, a discharge control circuit and a voltage conversion circuit. The photoelectric conversion element controls potential of first terminal of energy storage circuit according to received optical signal; the switch control circuit controls first terminal of energy storage circuit to be connected to or disconnected from conversion control node; the discharge control circuit controls conversion control node be connected to or disconnected from first voltage terminal; the voltage conversion circuit controls to output voltage signal outputted by output terminal according to second and/or third voltage signals. In the disclosure, by performing fingerprint identification by detecting duration length of the fourth voltage signal from output terminal, fingerprint image information can be obtained simply and efficiently, thereby improving fingerprint identification accuracy and preventing interference.
