1. A touch input device comprising:
a display panel;
a touch sensor including a driving electrode and a receiving electrode disposed in the display panel;
an electrode pattern disposed in the display panel; and
a controller configured to:
provide a first driving signal to the driving electrode of the touch sensor,
receive a touch detection signal from the receiving electrode of the touch sensor,
detect a touch position based on the touch detection signal, and
provide a second driving signal different from the first driving signal to the electrode pattern, wherein the electrode pattern comprises:
a plurality of first electrode patterns extending in parallel along a first direction; and
a second electrode pattern electrically connected to one end of each of the plurality of first electrode patterns.
