1. A pixel-driving circuit, comprising:
a switching circuit configured for being activated according to one of a first scan signal and a second scan signal to provide a corresponding one of a first data signal and a second data signal; and
a driving circuit connected with the switching circuit and a light-emitting component, wherein the driving circuit is configured for generating a driving current according to the corresponding one of the first data signal and the second data signal, and to provide the driving current to drive the light-emitting component;
wherein in driving periods of the first data signal and the second data signal, the first data signal and the second data signal are pulse signals having sub-cycles with different driving periods, and
wherein in all sub-cycles included in a total of the driving periods of the first data signal and the second data signal, the first data signal is a pulse signal having odd sub-cycles, and the second data signal is a pulse signal having even sub-cycles.
