Abstract: A polarity inversion driving method and apparatus for a liquid crystal display panel, and a liquid crystal display, is provided in order to solve the technical problem in the prior art that the interference strips are concentrated in one line, without increasing the power consumption of the liquid crystal display panel. The method comprises the steps of: generating N polarity control signals of different timings, wherein N is an integer and N≧2, and each polarity control signal is used to control a polarity voltage for sub-pixels in one or more columns of a liquid crystal display panel; and outputting the N polarity control signals to polarity control lines in the liquid crystal display panel, wherein each polarity control line corresponds to one polarity control signal.
