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.
