Pixel circuit and driving method therefor, display panel, and display apparatus

A pixel circuit, comprising:

• a plurality of driving transistors, wherein the plurality of driving transistors are configured to output different driving currents under control of a received control signal;
• and
• a plurality of gating sub-circuits, wherein 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 node;
• the light-emitting device node is configured to be electrically connected to a light-emitting device, and the gating sub-circuit 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, wherein
• 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.
