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.

Abstract: An electronic device has a force touch function. The electronic device includes an image display module having a touch electrode. A cover window attaches to a front surface of the image display module. A housing receives the image display module therein, and supports the cover window. A panel moving part is between the housing and the image display module. A driving circuit senses a touch force based on a distance between the image display module and the housing which are spaced from each other with the panel moving part interposed in-between.
