Abstract
A driving circuit of a liquid crystal display device including: a timing controller to output control signals and video data; a ramp signal generator to receive the ramp control signal output from the timing controller, and to generate and output a ramp signal by combining a gray voltage for each level and a precharging voltage for each gray voltage; and a data driver to provide video signals to respective data lines by sampling/holding the ramp signal output from the ramp signal generator according to a value of the video data.
