Touch driving circuit and touch display device for reducing noise of touch sensing signal according to display driving

A touch display device comprising:

• a panel on which a plurality of gate lines, a plurality of data lines and a plurality of subpixels are disposed;
• a plurality of emitting devices disposed at the plurality of subpixels;
• an encapsulation disposed on each emitting device;
• a plurality of touch electrode lines disposed on the encapsulation and including at least one touch electrode;
• and
• a touch driving circuit configured to drive the touch electrode lines,
• wherein the plurality of touch electrode lines comprises:
• a plurality of X-touch electrode lines disposed in a first direction;
• and
• a plurality of Y-touch electrode lines disposed in a second direction which is different from the first direction,
• wherein the touch driving circuit is configured to:
• output a touch driving signal to X-touch electrode lines of a first group of the plurality of X-touch electrode lines during a first period of a first touch sensing mode,
• output the touch driving signal to X-touch electrode lines of a second group of the plurality of X-touch electrode lines during a second period of the first touch sensing mode, and
• output the touch driving signal to at least one Y-touch electrode line of the plurality of Y-touch electrode lines during a third period of the first touch sensing mode.
