Abstract:
1. An apparatus for driving a liquid crystal display (LCD) device comprising: a liquid crystal display (LCD) panel that receives video signals, and displaying an image corresponding to the video signals; a backlight for emitting light on the LCD panel; a timing controller that controls the LCD panel and the backlight; a driving system outputs a clock signal from an external part, a vertical and horizontal synchronous signals to the timing controller; a signal generator which receives the clock signal and the horizontal signal applied to the timing controller, and modulates the received clock signal such that said signal generator generates a signal synchronized with the horizontal synchronous signal and which has the same frequency as that of the horizontal synchronous signal; and an inverter which receives said signal from the signal generator, allows a driving frequency of the backlight to be the same as that of the horizontal synchronous signal, and allows the received signal to be synchronized with the horizontal synchronous signal.
