A display device can include a display panel including multiple pixels each of which includes multiple sub-pixels. The display device can further include multiple data lines respectively connected to the multiple sub-pixels, multiple gate lines respectively connected to the multiple pixels, and N multiplexers (MUX) (N is a natural number larger than 1) disposed at input terminals of the multiple data lines. In one horizontal (H) period, a length of a turn-on period of a first MUX can be different from that of a turn-on period of an Nth MUX, where the one H period is a period in which a scan signal is supplied through one gate line.

An apparatus for driving a light source of a backlight unit includes: light sources; and a light source driver operating in an idle mode according to an input dimming signal and reducing a dimming value of an output dimming signal for adjusting brightness of the light sources by stages by mixing PWM control and PWM count control in a time-series manner to thus implement low dimming in the idle mode, wherein the dimming value of the output dimming signal is lowered to a first dimming value through the PWM control during a first period and subsequently lowered to a second dimming value lower than the first dimming value through the PWM count control during a second period that follows the first period.
