Abstract
Pixel circuit, driving method therefor and display apparatus are provided. The pixel circuit includes driving transistor, light-emitting device, storage capacitor, gating module, compensating module and switching module. First end of storage capacitor is connected to gate electrode of driving transistor, and second end thereof is connected to first electrode of driving transistor. Compensating module includes reset sub-module having output terminal connected to second electrode of driving transistor and configured to charge first electrode of driving transistor in reset stage to store threshold voltage of driving transistor in storage capacitor, and voltage dividing sub-module having first terminal connected to first electrode of driving transistor and second terminal connected to high-level input terminal such that voltage dividing sub-module is connected in series with storage capacitor. According to the invention, the effect of threshold voltage and IR drop on uniformity of display can be reduced, which improves display effect.
