摘要： A display device includes a backlight module, a backlight control module and a flicker removing module. The backlight module electrically connected between an input pin and an output pin which belong to the backlight control module, provides a backlight source to a display panel. The input pin receives a first voltage to control a continuity of an input current which is supplied to the backlight module and has no frequency variation. The flicker removing module electrically connected to the output pin receives a pulse width modulation signal and according to a duty cycle of the pulse width modulation signal, controls an output current outputted by the output pin, so as to control the backlight control module to control the input current according to the output current. The input current is associated with a backlight brightness of the backlight module.
