Abstract: A touch panel driving device that can easily perform a force sensing drive with a touch drive unit and a force drive unit that can be integrally formed in one-chip, a touch panel device can include the one-chip touch panel drive device, and a driving method thereof are provided. The touch panel device can include a bypass path that supplies a second touch sensing signal to a drive unit without passing through a sensing unit. Accordingly, the touch panel device can perform both touch sensing based on a first touch sensing signal and force sensing based on a second touch sensing signal using a single drive unit and prevent an erroneous second touch sensing signal from being transmitted to the drive unit due via the sensing unit, thereby easily and more accurately performing the force sensing.
