Abstract:
1. A liquid crystal display device, comprising: a liquid crystal display panel for displaying image data corresponding to a digital video signal; a digital video card for generating the digital video signal, a vertical synchronizing signal and a horizontal synchronizing signal; a controller for generating a dot clock signal and a dual gate start pulse using the vertical and horizontal synchronizing signals; a data driver for applying the digital video signal to data lines in response to the dot clock signal; and a gate driver for applying scanning signals having at least two signal voltage levels to gate lines in response to the dual gate start pulse, wherein during the application of a scanning signal to a pre-stage gate line, a subsequent scanning signal is applied to a gate line so that a voltage level of the scanning signal applied to the pre-stage gate line is attenuated by the subsequent scanning signal applied to the gate line.
