The invention provides a pixel circuit, a drive method of the pixel circuit, an organic light-emitting display panel and a display device. A display control module and a fingerprint identification module are arranged. A first scanning line, a second canning line, a control line, a data line, a second signal source, a third signal source and the anode of an organic light-emitting diode are connected with the display control module. The display control module is used for enabling a light-emitting drive signal of the organic light-emitting diode to be independent of the threshold voltage of the drive transistor under the control of a first scanning signal, a second scanning signal and a control signal. The fingerprint identification module is connected with the first scanning line, the second scanning line, a fourth signal source and a signal reading line. The fingerprint identification module is used for achieving fingerprint identification function and the touch detecting function under the control of the first scanning signal and the second scanning signal. By the adoption of the display control module and the fingerprint identification module, the evenness of the luminance of the display panel can be improved, the image display effect of the display device can be improved, and efficient integration of display drive, fingerprint identification and touch detection is achieved.
