(EN)
The invention discloses driving methods and a driving device of a display panel, equipment and a storage medium. According to the method, when a current time sequence is a first preset time sequence,negative polarity common electrode voltage of first predetermined voltage is adopted to carry out negative polarity driving on high voltage positive polarity sub-pixels and and low voltage negative polarity sub-pixels in a first row of pixel units and a second row of pixel units; positive polarity common electrode voltage of second predetermined voltage is adopted to carry out positive polarity driving on high voltage negative polarity sub-pixels and low voltage positive polarity sub-pixels in a second row of pixel units and a third row of pixel units, interlaced arrangement is carried out onhigh voltage pixels and low voltage pixels, and positive and negative polarity driving is carried out on the same according to common electrode voltage; and therefore, the view angle color error problem is solved, and the defects that power consumption is increased, temperature rises, and panel brightness is lowered due to driving amplitude increasing are avoided, a display effect is improved, anduser experience is improved.
