Abstract: The present application discloses a method for driving a display panel including multiple groups of sub data lines and each group includes multiple sub data lines coupled to a corresponding data line via a mux device. The method includes providing multiple data signals originated from the voltage signal sequentially in time respectively to the multiple sub data lines in each group. The multiple data signals includes a first data signal characterized by a first pulse width being received at a first time by a first sub data line in the group and a second data signal characterized by a second pulse width larger than the first pulse width being received at a second time later than the first time by a second sub data line in the group. A data signal received earliest in time by a sub data line has a shortest pulse width.
