Abstract: 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.

Abstract: A gate driver and a method for adjusting output channels thereof are provided. The method includes: setting a target number of the output channels; dividing the output channels into a first channel chain and a second channel chain; enabling a scanning operation of the first channel chain according to a clock signal and counting the clock signal to obtain a counting value; and when the counting value reaching a threshold value, enabling a scanning operation of the second channel chain, wherein the threshold value is determined according to a difference value between the target number and the physical number.
