摘要： A liquid crystal display with improved color reproducibility and image quality is presented. The liquid crystal display includes a liquid crystal panel assembly including a plurality of pixels, a signal controller, and a data driver. The signal controller stores a dithering data patterns, selects one of the dithering data patterns based on input image data having a first bit number, and converts the input image data to output image data having a different bit number using the selected dithering data pattern. The data driver applies data voltages to the pixels, the data voltages corresponding to the output image data from the signal controller. Frequency of the input image signal and the output image signal from the signal controller is each about 120 Hz, and the dithering data patterns are repeated every eight frames. The signal controller includes a look-up table that stores the dithering data patterns.
