Claim 9:
10. A timing control device for a display panel, comprising:
a control circuit, configured to generate a plurality of gate scanning control signals and a data transmission control signal, wherein the gate scanning control signals are sequentially enabled for driving the display panel, and the gate scanning control signals have a same period and different phases;
wherein in response to that the display refresh rate changes from a higher first frequency to a lower second frequency, the control circuit reduces 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, the control circuit increases the duty cycle of the data transmission control signal to generate the adjusted data transmission control signal, wherein the control circuit reduces or increases the duty cycle of the data transmission control signal by changing a trailing edge of the data transmission control signal or changing a pulse width of the data transmission control signal.
