Abstract: A pixel circuit is provided. A first terminal and a second terminal of a light-emitting sub-circuit are coupled to a first power supply terminal and a compensation sub-circuit respectively. A short-circuiting sub-circuit is coupled to the first terminal and the second terminal of, and short-circuits under control of a short-circuiting control terminal, the light-emitting sub-circuit. The compensation sub-circuit is coupled to a data voltage terminal, a reference voltage terminal, and a first electrode and a gate electrode of a driving transistor. The light-emitting sub-circuit emits a light of brightness in a level corresponding to a current flowing therethrough. The compensation sub-circuit loads, based on the data voltage terminal and the reference voltage terminal, a driving voltage related to a threshold voltage of the driving transistor onto the gate electrode of the driving transistor, such that a current flowing through the driving transistor is not influenced by its threshold voltage.
