    摘要： A liquid crystal display (LCD) device and a driving method can produce reduced direct current image sticking and flicker. An LCD panel for the LCD device has liquid crystal cells having a common same color in each horizontal line and has columns of liquid crystal cells having a repeating sequence of color, a timing controller for generating a polarity control signal such that the polarity control signal is varied at intervals of one frame period, a data driving circuit supplying data voltages to the data lines in response to the polarity control signal, and a gate driving circuit supplying scan pulses to the gate lines. The liquid crystal cells include first liquid crystal cell groups supplied with data voltages having polarities inverted from polarities the previous frame period, and second liquid crystal cell groups supplied with data voltages having polarities identical to the polarities supplied in the previous frame period.

    摘要： A liquid crystal display (LCD) device and a method for driving the LCD device are disclosed. The LCD device includes a frame rate adjusting circuit for controlling a frame rate to be maintained at a 1-fold rate in frame periods other than an Nth frame period (“N” is a multiple of 8 or more), while being increased to an “i”-fold-accelerated rate (“i” is a positive integer of 2 or more) in the Nth frame period, to output reference timing signals in the frame periods other than the Nth frame period, and to output accelerated timing signals in the Nth frame period, a timing controller for generating data and gate timing control signals, based on at least one of each reference timing signal and each accelerated timing signal, and a logic circuit for accelerating a frequency of a polarity control signal in the Nth frame period.
