An apparatus of driving a liquid crystal display (LCD) includes a gray voltage generator generating a range of gray voltages that correspond to different LC light transmittance levels. These gray voltages, along with image data, are fed into a data driver. The data driver converts the gray voltages to a data voltage that properly generates the image indicated by the image data. The gray voltage values are chosen from a wider range of values than the pixel voltages, and this conversion may include determining a conversion factor based on the relative range sizes. This conversion may also include calculating the voltage difference between the previous data and the current data and adjusting the data voltage according to the magnitude of this difference. Generally, the larger the voltage difference, the larger is the data voltage magnitude that is needed to bring the pixel voltage to the target voltage within limited time.
