Abstract
A pixel circuit includes a data writing sub-circuit, a reset sub-circuit and a leakage prevention sub-circuit. The data writing sub-circuit is configured to: in a data writing period, store a light-emitting compensation signal in response to a gate scan signal from a first scan signal terminal and a data signal from a data signal terminal; and in a light-emitting period, assist in controlling the light-emitting control sub-circuit to be turned on according to the light-emitting compensation signal. The reset sub-circuit is configured to: in a reset period, transmit an initial voltage signal to the data writing sub-circuit and the leakage prevention sub-circuit in response to a reset scan signal from a second scan signal terminal. The leakage prevention sub-circuit is configured to: in the data writing period, store another light-emitting compensation signal; and in the light-emitting period, inhibit leakage of the reset sub-circuit according to the another light-emitting compensation signal.
