Abstract
An apparatus and method for driving a liquid crystal display device are disclosed. The apparatus includes a liquid crystal panel with pixels defined by data and gate lines. A gate driver provides different gate pulses to the odd-column pixels than to the even-column pixels. The gate pulses have different voltages and/or widths. Data drivers provide data voltages having a positive or negative polarity to the data lines. A timing controller controls the gate and data drivers and supplies gate clock pulses that have different voltages and/or widths to the gate driver.
