Abstract: Liquid crystal display devices and backlight driving methods thereof are provided. A backlight module of the liquid crystal display device includes a light-emitting unit, a calculation unit, a comparison unit, and a control unit. The calculation unit calculates a first preset backlight brightness value of a backlight partition according to a partition average brightness value and a partition maximum brightness value of a corresponding display partition under a current frame display image. The comparison unit compares a second preset backlight brightness value of the backlight partition under a previous frame display image and the first preset backlight brightness value, and outputs a comparison result. The control unit outputs a first brightness driving value of the backlight partition under the current frame display image according to the comparison result. The light-emitting unit emits light in the backlight partition according to first brightness driving value.
