Abstract
The present invention provides a pixel circuit and a driving method thereof, a display device. The pixel circuit comprises a display driving module, a compensation module, a light emitting module and a fingerprint identification module. The compensation module is connected with the display driving module, a first signal terminal, a second signal terminal, a third signal terminal, a first voltage terminal, a data signal terminal and a common voltage terminal respectively. The display driving module is further connected with the light emitting module. The light emitting module is further connected with an enable signal terminal, the first voltage terminal and a second voltage terminal. The fingerprint identification module is connected with a fourth signal terminal, a fifth signal terminal and a readout signal line respectively.
