    摘要: A liquid crystal display includes a liquid crystal display panel for displaying picture images, and a color correction unit. Upon receipt of raw RGB picture data corresponding to raw RGB gamma curves, the color correction unit generates corrected RGB picture data based on values over a predetermined imaginative gamma curve established in accordance with the characteristic of the liquid crystal display panel. The color correction unit stores values over corrected RGB gamma curves corresponding to the corrected picture data, and gamma-corrects the raw RGB picture data based on values over the stored corrected RGB gamma curves, thereby displaying the picture images.

    摘要: 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.
