a display panel, displaying an image frame, each frame period comprising an image scanning period for displaying an image and an image occlusion period not for displaying the image;

a backlight unit;

a backlight driving circuit, coupled to the backlight unit; and

a control circuit, coupled to the display panel and the backlight driving circuit, wherein when a duration of the image occlusion period is shorter than a preset duration, a first pulse signal and a second pulse signal are respectively provided in a first light emitting period and a second light emitting period in each frame period, so as to control the backlight driving circuit to output a first pulse current and a second pulse current to drive the backlight unit provide a first backlight and a second backlight, wherein the first pulse current is greater than the second pulse current, wherein the control circuit continuously provides the second pulse signal when the duration of the image occlusion period is longer than or equal to the preset duration, so as to control the backlight driving circuit to continuously output the second pulse current to drive the backlight unit to continuously provide the second backlight.
