1. A driving device for a touch panel including at least one capacitance node, the driving device comprising:

  • a first switching element that is coupled to a first electrode of the at least one capacitance node and is configured to selectively apply, to the first electrode, a driving voltage for generating an electric potential difference in the at least one capacitance node; and

    a second switching element that is coupled to the first electrode and is configured to selectively apply, to the first electrode, a sensing voltage for sensing a variation in the capacitance of the at least one capacitance node.
