Abstract: A method for driving a display panel and a display panel thereof. Method comprises: A driving circuit regulates electrical levels of the driving signals in a driving cycle transmitting to a first/second/third charging control unit corresponding to a first/second/third color sub-pixel unit respectively. Therefore, the first color sub-pixel unit is charged via a first thin-film-transistor of the first charging control unit by charging data, the second color sub-pixel unit is charged via a first thin-film-transistor and a second thin-film-transistor of the second charging control unit by said charging data, and the third color sub-pixel unit is charged via a first thin-film-transistor of the third charging control unit by charging data. Therefore, electrical level switching of driving signals by driver circuit is reduced resulting reduced power consumption of driving display panel.
