Abstract
A pixel circuit includes a driving transistor, a reset sub-circuit, a leakage prevention sub-circuit and a data writing sub-circuit. The reset sub-circuit is configured to, under control of a first scanning signal, transmit a reference voltage signal to a first electrode of the driving transistor. The leakage prevention sub-circuit is configured to, under control of a second scanning signal, connect the first electrode of the driving transistor to a control electrode of the driving transistor. The data writing sub-circuit is configured to, under control of a third scanning signal, transmit a data signal to a second electrode of the driving transistor. The reset sub-circuit and the data writing sub-circuit are turned on sequentially when the leakage prevention sub-circuit is turned on; and the reset sub-circuit is turned on at least once when the leakage prevention sub-circuit is turned off.
