Abstract:
The present disclosure provides a pixel circuit and a driving method thereof, a display device. The pixel circuit includes a reset sub-circuit, a compensation sub-circuit, a data writing sub-circuit, a storage capacitor, a driving transistor, a light emitting control sub-circuit and a light emitting sub-circuit. The compensation sub-circuit may write a threshold voltage of the driving transistor into a gate of the driving transistor in a date writing stage, so that magnitude of a drive current output by the driving transistor is independent of the threshold voltage of the driving transistor in a light emitting stage.

Claim (Index 8):
A driving method of a pixel circuit, wherein the driving method is used for driving the pixel circuit according to  claim 1 , the pixel circuit comprises: a reset sub-circuit, a compensation sub-circuit, a data writing sub-circuit, a storage capacitor, a driving transistor, a light emitting control sub-circuit and a light emitting sub-circuit, the driving method of the pixel circuit includes:\n a reset stage, in which a reset signal provided by a reset signal terminal is at a first potential, and in which, under the control of the reset signal, the reset sub-circuit outputs an initialization signal from an initialization signal terminal to a first node and outputs the initialization signal from a reference signal terminal to a second node, the initialization signal being at a second potential; a data writing stage, in which a driving signal provided by a driving signal terminal is at the first potential, in which the data writing sub-circuit outputs a data signal from a data signal terminal to the second node and outputs a reference signal to a second electrode of the driving transistor, and in which the compensation sub-circuit writes a threshold voltage of the driving transistor into the first node under the drive of the driving signal and a third node; and a light emitting stage, in which the light emitting control sub-circuit outputs the reference signal to the second node and outputs a first power signal from a first power terminal to the third node, in which the storage capacitor adjusts a potential of the first node according to a potential of the second node, and in which, under the drive of the first node and the third node, the driving transistor outputs a drive current to the light emitting sub-circuit and drives the light emitting sub-circuit to emit light.
