Abstract: A backlight driving circuit includes a pulse width modulator, at least one time-delay sub-circuit and a driving sub-circuit. The pulse width modulator is configured to transmit a control signal including a plurality of pulses. The at least one time-delay sub-circuit is configured to delay at least one pulse of the control signal from the pulse width modulator that is transmitted to the at least one time-delay sub-circuit by a set time. The driving sub-circuit is coupled to the at least one time-delay sub-circuit, and the driving sub-circuit is configured to drive at least one of a plurality of light-emitting devices in a backlight module to be turned on or off according to a control signal from the at least one time-delay sub-circuit obtained after the at least one pulse is delayed.
