Abstract

A dimming control method of a backlight unit of a liquid crystal display (LCD) device driven at a driving frequency (f) of 60 Hz or lower includes a first step of driving the backlight unit using a first dimming value, and a second step of driving the backlight unit using a second dimming value higher than the first dimming value. The first step and the second step are alternately repeated and a repetition number of the second step within one period T of a driving frequency (f) is set to satisfy a condition of “{(60/f)−1}”. Here, f is a natural number lower than 60.
