Abstract: A control method for a display device including a display panel and a backlight device is provided. The display panel includes multiple display zones. The backlight device includes multiple backlight zones. The backlight zones are sequentially illuminated. The illumination time when the first backlight zone is illuminated satisfies followings: t1≥(m/n+a)×t2+t3, t1 is the time from the start of displaying each frame of an image to the illumination of the first backlight zone, m is the number of pixel rows, n is the number of the backlight zones, a is the number of pixel rows occupied by a portion of a light-emitting area that extends beyond the corresponding backlight zone when the backlight zone is illuminated, t2 is the scanning time for each pixel row of the display panel, and t3 is response time when the pixel row receives a row scanning signal.
