    Abstract: Disclosed is a force sensing display device which sequentially supplies a driving signal to at least two force sensing sensors and senses forces pressing the force sensing sensors by using sensing signals sequentially received from the force sensing sensors. The force sensing display device includes a panel including a plurality of gate lines and a plurality of data lines, a gate driver driving the plurality of gate lines, a data driver driving the plurality of data lines, a controller controlling the gate driver and the data driver, a force sensing panel disposed adjacent to the panel and including at least two force sensing sensors, and a force sensing unit sequentially supplying a driving signal to the at least two force sensing sensors and sensing forces respectively pressing the at least two force sensing sensors by using sensing signals sequentially received from the force sensing panel.

    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.
