The driving system for driving a display panel includes a timing controller and a source driving circuit. The source driving circuit includes a plurality of output channels and a plurality of shift registers respectively corresponding to the output channels. The plurality of shift registers are classified into a plurality of shift register series, among which a first shift register series includes a first shift register being as one end and a second shift register being as the other end, and a second shift register series includes a third shift register being as one end and a fourth shift register being as the other end. The timing controller is connected to the first shift register, the second shift register, the third shift register, and the fourth shift register, and transmits a first start pulse to the first shift register and a second start pulse to the third shift register.
