Abstract:
1. A display system, comprising: a display device, which comprises indium tin oxide (ITO) resistors; a driving circuit, disposed on the display device, for driving the display device; a flexible printed circuit (FPC), externally coupled to the display device; a charge pump circuit, disposed only on the FPC, for generating at least an output voltage to the driving circuit; and a control circuit, disposed on the display device and coupled to the driving circuit, for generating a plurality of control signals to control the charge pump circuit; wherein the charge pump circuit has a plurality of control ports coupled to the control circuit for receiving the control signals generated from the control circuit, respectively; and the charge pump circuit is disposed only on the FPC and is coupled to each of the driving circuit and the control circuit through the FPC without being directly connected to any of the driving circuit and the control circuit, so as to prevent a voltage converting efficiency of the charge pump circuit from being limited by the ITO resistors of the display device.
