1. A touch display device, comprising:
a plurality of X-touch electrode lines disposed in a first direction;
a plurality of Y-touch electrode lines disposed in a second direction; and
a touch driving circuit configured to:
drive the plurality of X-touch electrode lines and the plurality of Y-touch electrode lines during divided periods of one sensing unit period in a first touch sensing mode,
drive X-touch electrode lines of a first group of the plurality of X-touch electrode lines during a first period and remaining X-touch electrode lines of a second group of the plurality of X-touch electrode lines during a second period, and
drive all of the plurality of Y-touch electrode lines simultaneously in a remaining period except for the first period and the second period in the sensing unit period,
wherein a number of all channels driving the plurality of X-touch electrode lines is more than a number of channels driving the plurality of Y-touch electrode lines,
wherein the first period and the second period are time-divided, and
wherein the touch driving circuit does not drive the remaining X-touch electrode lines of the second group of the plurality of X-touch electrode lines during the first period, the touch driving circuit does not drive the X-touch electrode lines of the first group of the plurality of X-touch electrode lines during the second period.
