1. 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 a display refresh rate changes from a higher first frequency to a lower second frequency, the control circuit delays phases of the plurality of gate scanning control signals to generate a plurality of adjusted gate scanning control signals or, in response to that the display refresh rate changes from a lower first frequency to a higher second frequency, the control circuit shifts the phases of the plurality of gate scanning control signals to be earlier to generate the plurality of adjusted gate scanning control signals, for driving a display panel under the second frequency as the display refresh rate.
