Abstract: A driving circuit of a display panel and a driving method thereof are disclosed. The display panel includes multiple data lines and fan-out traces connected to the multiple fan-out traces in one-to-one correspondence. The driving circuit includes multiple compensation circuits and a signal input unit. Each compensation circuit includes an input terminal and an output terminal. The output terminals of the multiple compensation circuits are respectively connected to the plurality of fan-out traces. At least two gear positions are set in each compensation circuit. When the gear position of the compensation circuit increases, a capacitance value or a resistance value of the compensation circuit gradually decreases. The signal input unit outputs data signals to the input terminals of the multiple compensation circuits. Each compensation circuit selects a gear position depending on a gray scale of a data signal or a scanning time during progressive scanning of the display panel.
