| Zusammenfassung: | A driving device and a touch panel are provided. The driving device includes a first switcher and a second switcher. The first switcher is coupled to a first electrode of a capacitance node of the touch panel and is configured to selectively apply, to the first electrode, a driving voltage for generating an electric potential difference in the capacitance node. The second switcher is coupled to the first electrode and 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. |
