Claim 12:
13. A control method for a display device, comprising:
generating a plurality of gate scanning control signals and a data transmission control signal, wherein the gate scanning control signals are sequentially enabled for driving a display panel, and the gate scanning control signals have a same period and different phases;
in response to that the display refresh rate changes from a higher first frequency to a lower second frequency, reducing the duty cycle of the data transmission control signal to generate the adjusted data transmission control signal; or, in response to that the display refresh rate changes from a lower first frequency to a higher second frequency, increasing the duty cycle of the data transmission control signal to generate the adjusted data transmission control signal, wherein the duty cycle of the data transmission control signal is reduced or increased by changing a trailing edge of the data transmission control signal or changing a pulse width of the data transmission control signal.
