Abstract: A liquid crystal display includes a system and a liquid crystal module. The system detects an input frame frequency, generates a DISP signal indicating the input of an abnormal signal at a high logic level when the detected frame frequency is within a previously determined range, and generates the DISP signal at a low logic level when the detected frame frequency is beyond the previously determined range. The liquid crystal module includes a signal processing unit which selectively outputs digital video data for implementing a normal screen and digital black data for implementing a black screen in response to the DISP signal.

Abstract: 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.
