Touch display device and touch driving circuit

A touch display device comprising:

• a first driving touch electrode included in a display panel of the touch display device, the first touch electrode applied with a first driving signal having a first frequency during a first driving period;
• a second driving touch electrode included in the display panel, the second driving touch electrode applied with a second driving signal having a second frequency that is different from the first frequency during the first driving period;
• a sensing touch electrode crossing the first driving touch electrode and the second driving touch electrode;
• and
• a touch driving circuit configured to detect a signal from the sensing touch electrode during the first driving period,
• wherein the touch driving circuit is configured to separate the detected signal into a first sensing signal having the first frequency and a second sensing signal having the second frequency, and output the first sensing signal and the second sensing signal.

A touch display device comprising:

• a display panel including a first touch electrode line, a second touch electrode line, a signal line to which a display signal is applied to display an image on the display panel, and a light emitting device comprising a first electrode and a second electrode, the first electrode is applied the display signal and the second electrode is overlapped by the signal line;
• and
• a touch driving circuit configured to drive the first touch electrode line with a first touch driving signal having a first touch driving frequency, and drive the second touch electrode line with a second touch driving signal having a second touch driving frequency that is different from the first touch driving frequency,
• wherein the first touch electrode line is included in a first area of the display panel and the second touch electrode line is included in a second area of the display panel that is different from the first area,
• the touch display device further comprising:
• a third touch electrode line disposed in the first area and applied a third driving signal having a same frequency as the first touch driving frequency of the first driving signal;
• and
• a fourth touch electrode line disposed in the second area and applied a fourth driving signal having a same frequency as the second touch driving frequency of the second driving signal.
