1. A method for driving a display apparatus, the method comprising:
in a first refresh period that corresponds to a first refresh rate and includes a first effective phase and at least one first ineffective phase, outputting a first image frame signal to a display panel of the display apparatus in the first effective phase, and outputting a first ineffective data signal to the display panel in a first ineffective phase; and
in a second refresh period that corresponds to a second refresh rate and includes a second effective phase and at least one second ineffective phase, outputting a second image frame signal to the display panel in the second effective phase, and outputting a second ineffective data signal to the display panel in a second ineffective phase;
wherein the first refresh rate is different from the second refresh rate, and the first ineffective data signal and the second ineffective data signal have different magnitudes in voltage;
wherein the first refresh rate is less than the second refresh rate;
the first refresh period includes at least two first frame periods, a first first frame period in the at least two first frame periods is a first writing frame, and each first frame period in the at least two first frame periods other than the first writing frame is a first holding frame;
the first effective phase is included in the first writing frame; and
the first holding frame includes a first display control phase and a first free phase, a position of the first display control phase in the first holding frame and a position of the first effective phase in the first writing frame are same; the first free phase is between the first display control phase and the first writing frame, and the first free phase is one of the at least one first ineffective phase.
