A display system includes a display device, a driving circuit, a flexible printed circuit (FPC), a charge pump circuit and a control circuit. The driving circuit is disposed on the display device, and utilized for driving the display device. The FPC is externally coupled to the display device. The charge pump circuit is disposed on the FPC, and utilized for generating at least an output voltage to the driving circuit. The control circuit is disposed on the display device and coupled to the driving circuit, and utilized for generating a control signal to control the charge pump circuit. The charge pump circuit has a control pin coupled to the control circuit for receiving the control signal generated from the control circuit.
