Abstract:
A polarity inversion driving method, a driving apparatus and a liquid crystal display device, for attenuating the flickers due to POL inversion. The polarity inversion driving method is used for inversion of polarity of pixels on the liquid crystal panel, and comprises: generating a polarity inversion reference signal for reflecting selection of polarity of each row of pixels on the liquid crystal panel; generating a control signal comprising control levels generated in m frames, where m is an integer higher than or equal to two, wherein width of the control level in each of the m frames is gradually increased in chronological order to be equal to a time length of one frame; as an alternative, the width of the control level in each of the m frames is gradually decreased in chronological order from the time length of one frame to zero; and generating a polarity inversion signal from the polarity inversion reference signal and the control signal.
