Claim 17:
18. A touch display device comprising:
a display panel including a plurality of touch electrodes, the plurality of touch electrodes including a first touch electrode and a second touch electrode; and
a touch driving circuit configured to drive the plurality of touch electrodes, the touch driving circuit including:
a group sensing control switch between the first touch electrode and the second touch electrode, the group sensing control switch configured to electrically connect together the first touch electrode and the second touch electrode or electrically disconnect the first touch electrode and the second touch electrode; and
a first sensing unit configured to sense touch of the display panel,
wherein during a first mode of the touch display device during which the group sensing control switch is turned off, the first sensing unit is electrically connected to the first touch electrode but not the second touch electrode to sense touch of the first touch electrode,
wherein during a second mode of the touch display device during which the group sensing control switch is turned on, the first sensing unit is electrically connected to the first touch electrode and the second touch electrode to sense touch of the first touch electrode and the second touch electrode.
