Abstract
The present disclosure proposes a method and a system of controlling backlight driving. The method includes receiving an initial-pulse-width modulating signal and outputting a corresponding pulse-width modulating signal according to the initial-pulse-width modulating signal. The pulse-width modulating signal is used to control a corresponding LED string to illuminate. A cycle of each of the pulse-width modulating signals is the same with a predetermined phase difference.
