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.

Abstract: Embodiments of the present disclosure provide a pixel circuitry and a driving method thereof. In the pixel circuitry, the reset circuit provides an initialization signal to a first node and one end of the light emitting device based on a reset signal. The driving transistor provides a driving current based on the voltage of the first node. The data signal write circuit provides a data signal to a third node based on a strobe signal. The compensation circuit couples a second node to the first node based on the strobe signal. The voltage supply circuit provides a first voltage signal to the second node based on a control signal. The control circuit provides a driving current provided by the driving transistor to the light emitting device based on the control signal. The light emitting device emits light according to the driving current.
