Abstract:
An data driver for driving an LCD device includes a modulator that generates modulated data from input data; and a control circuit to selects between converting the modulated data to first analog data of a driving output and converting the input data to second analog data of the driving output, and to supply the driving output to the plurality of data lines. The driving output may provide a gray-to-gray response time of the LCD device substantially the same as one of a black-to-white and a white-to-black response time of the LCD device by reducing actual liquid crystal response time of the LCD device.
