Abstract: A touch display driving integrated circuit (IC) includes a touch driver IC configured to be connected to touch electrodes through touch sensing lines and provide a sensing signal to first touch sensing lines among the touch sensing lines in a touch period. The touch driver IC is further configured to apply a common voltage to second touch sensing lines among the touch sensing lines and apply a voltage different from the common voltage to third touch sensing lines different from the second touch sensing lines in a display period.
