Abstract
A signal generation apparatus, a driving chip, a display system and an LED displaying driving method are described. A circuit comprises a first generation device for generating a first PWM wave with period T1; a second generation device for generating a delayed clock signal with period T2, T1=NT2, the first time is delayed by F×T2 compared with the second time, the first time is the time corresponding to a first rising edge of the delayed clock signal, the second time is the time corresponding to a first rising edge of the first PWM wave; a third generation device for generating a third PWM wave with period T3 according to the first PWM wave the delayed clock signal, T3=T1+F×T2, a first rising edge of the third PWM wave is synchronous with the first rising edge of the first PWM wave.
