Abstract: A drive circuit for driving a display panel includes a dynamic refresh unit, a timer, and a black insertion drive unit. The dynamic refresh unit is configured to output a dynamic refresh signal, so as to control the display panel to display a plurality of frames in sequence. A frame time of each of the frames is adjusted according to the dynamic refresh signal. The timer is configured to compute a black insertion time signal. The black insertion drive unit is configured to output a black insertion drive signal according to the black insertion time signal, so as to perform black insertion on the frames.
