Abstract: A driving method includes: receiving a frequency modulation signal; generating a frequency modulation synchronization signal; generating an auxiliary synchronization signal when a rising edge of the frequency modulation synchronization signal is in a writing phase of a light-emitting unit group to which light-emitting data signals are last written in a previous frame period; and controlling, based on the auxiliary synchronization signal, a writing phase of a light-emitting unit group to which light-emitting data signals are to be first written in a current frame period to be staggered with the writing phase of the light-emitting unit group to which light-emitting data signals are last written in the previous frame period. The light-emitting unit group to which light-emitting data signals are last written in the previous frame period belongs to same cluster as the light-emitting unit group to which light-emitting data signals are to be first written in the current frame period.
