1. A driving circuit, comprising:
a data writing circuit, coupled to a first scanning signal end, a data signal end and a first node, and configured to, under control of a first scanning signal received at the first scanning signal end, write a data signal received at the data signal end into the first node;
a control circuit, coupled to the first node, a second node and a third scanning signal end, and configured to, under control of a third scanning signal received at the third scanning signal end, write a data signal received by the first node into the second node;
a driving sub-circuit, coupled to the second node, a driving voltage end and a light-emitting component, and configured to, under control of a data signal received at the second node, use a driving voltage received at the driving voltage end to drive the light-emitting component; and
a shift register circuit, wherein the shift register circuit is coupled to a driving voltage end, a register signal end, and the third scanning signal end; and the shift register circuit is configured to, under control of a register signal received at the register signal end, output, to the third scanning signal end, a driving voltage received at the driving voltage end to which the shift register circuit is coupled;
wherein the shift register circuit further comprises a first trigger, wherein a first input end of the first trigger is connected to a driving voltage end via a first resistance, a second input end of the first trigger is connected to the register signal end, and an output end of the first trigger is connected to the third scanning signal end.
