Abstract: A control method of a time sequential control signal and a driving circuit are provided. A main TCON chip and an assist TCON chip compute corresponding frame rates according to pixel clock signal frequencies, then call a corresponding table, and transmit the table to a first driving unit and a second driving unit respectively. The first driving unit and the second driving unit respectively perform scanning on rows and columns of pixels to allow complicated dynamic images to be displayed with smooth motions.
