The pixel circuit comprises: a driving transistor (Tr), a storage capacitor (Cs), a data writing module (10), a light-emitting element (20) and a predetermined voltage writing module (30). A first terminal of the storage capacitor (Cs) is connected to a gate of the driving transistor (Tr) and a second terminal thereof is connected to a second electrode of the driving transistor (Tr). The predetermined voltage writing module (30) is configured to make the second electrode of the driving transistor (Tr) reach a predetermined potential in a pre-charging phase and a compensating phase; and the data writing module (10) is configured to store a data voltage of a data line into the storage capacitor (Cs) in the compensating phase. In the pixel circuit and the driving method thereof and the display apparatus, the driving current is not affected by the threshold voltage, and influence of the voltage across the light-emitting element on the driving current is eliminated, thereby the uniformity of luminance of the light-emitting element is raised and improving the display effect of the display apparatus is improved.
