1. A touch panel, comprising:

  • a touch sensor for outputting at least one sensing signal corresponding to at least one object when the at least one object touches the touch panel;

    a liquid crystal panel comprising a common electrode, the liquid crystal panel used for executing at least one corresponding operation according to the at least one sensing signal; and

    a reverse circuit having a first terminal coupled to the liquid crystal panel for receiving common voltage ripples of the common electrode of the liquid crystal panel coupled to the touch sensor, and a second terminal coupled to the touch sensor for outputting reversed common voltage ripples;

    wherein the touch sensor is located on the liquid crystal panel.
