Claim 8:
9. The pixel circuit according to claim 1, wherein the light-emitting device is further electrically connected to a second power supply voltage terminal; and
each sub-pixel circuit further includes a writing compensation sub-circuit and a light-emitting control sub-circuit;
the writing compensation sub-circuit is electrically connected to a writing control terminal, the data terminal and the driving sub-circuit; and the writing compensation sub-circuit is configured to write the data signal output by the data terminal into the driving sub-circuit under control of a signal from the writing control terminal, so as to compensate for a threshold voltage of the driving sub-circuit; and
the light-emitting control sub-circuit is electrically connected to an enable terminal, a first power supply voltage terminal, the driving sub-circuit and the light-emitting device; and the light-emitting control sub-circuit is configured to close a current path between the first power supply voltage terminal and the second power supply voltage terminal under control of a signal from the enable terminal, so that the driving current is transmitted to the light-emitting device;
the driving sub-circuit includes a driving transistor;
a gate of the driving transistor is electrically connected to the reset sub-circuit, a first electrode of the driving transistor is electrically connected to the writing compensation sub-circuit, and a second electrode of the driving transistor is electrically connected to the light-emitting control sub-circuit.
