Method for reducing resonance energy of an LCD panel and related LCD device

A charge pump circuit includes an input end, a first reservoir capacitor, a second reservoir capacitor, a first output end, a second output end, and a charge pump unit. The input end is utilized for receiving an input voltage. The charge pump unit includes a first flying capacitor, a second capacitor, a plurality of switches, and a control unit. The control unit is utilized for controlling on/off state of the plurality of switches so that the first flying capacitor provides a positive charge pump voltage to the first output end or a negative charge pump voltage to the second output and the second flying capacitor provides a positive charge pump voltage to the first output end through charge and discharge process.
