Abstract
A liquid crystal display (LCD) device and a driving method where the LCD device includes a data controller for interleaving one of black gray scale data and intermediate gray scale data into input digital video data to input digital video data in a specific period preceding a second one of two successive frame periods in which data voltages having the same polarity are successively supplied to liquid crystal cells. A timing signal controller generates a data timing signal and a gate timing signal, based on an input timing signal, and accelerates a frequency of the data timing signal and a frequency of the gate timing signal in the specific period. A data driving circuit is included for converting the interleaved digital video data into an analog voltage in response to the data timing signal, and supplying the analog voltage to data lines in the specific period.
