The embodiments of the present disclosure provide a driving method and driving apparatus of a display panel. The driving method comprises: dividing a driving period into N sub-periods, each of which is further divided into a first time period and a second time period, where N is a positive integer greater than or equal to 1; and applying a first common voltage to a first common electrode in the first time period and applying a second common voltage to the first common electrode in the second time period, wherein the second time period is longer than the first time period in duration. In the present disclosure, a common voltage in a modulation mode is applied to the first common electrode, so that an average arrangement direction of liquid crystal molecules in a pixel unit changes in a driving period.
