Abstract: A pixel circuit includes a plurality of driving transistors and a plurality of gating sub-circuits. The plurality of driving transistors are configured to output different driving currents under control of a received control signal. Each gating sub-circuit is electrically connected to a respective selection signal terminal, a scanning signal terminal, a respective driving transistor and a light-emitting device, and is configured to be turned on under control of a scanning signal from the scanning signal terminal and a selection signal from the selection signal terminal to transmit a driving current from the connected driving transistor to the light-emitting device. Within a frame period, one of a plurality of selection signal terminals respectively electrically connected to the plurality of gating sub-circuits outputs a selection signal.
