    Abstract: A pixel circuit, a driving method thereof, and a display apparatus are provided. The pixel circuit includes a leakage current compensation module, configured to output a leakage current compensation voltage to a gate of a driving transistor at a light-emitting control stage of the pixel circuit, to control a potential change of the gate of the driving transistor to be opposite to a potential change caused by a leakage current at the gate of the driving transistor. At the light-emitting stage, the voltage of the gate of the driving transistor is compensated for by the leakage current compensation module, to compensate for the potential change caused by the leakage current, ensuring high stability of potential at the gate of the driving transistor, making the driving current generated by the driving transistor highly stable, and alleviating the flickering problem when the display apparatus displays images.
