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.

Abstract: A touch display driving integrated circuit (IC) includes a touch driver IC and a source driver IC. The touch driver IC is to be connected to touch electrodes through touch sensing lines. The touch driver IC provides a sensing signal to first touch sensing lines among the touch sensing lines in a touch period, and applies a common voltage to the first touch sensing lines before the touch period is terminated. The source driver IC is to be connected to pixels through data lines.

Abstract: An operating method of a touch display driving integrated circuit that is connected with a touch display panel through touch sensing lines and data lines is provided. The method includes applying a common voltage to each touch sensing line, increasing voltages of the touch sensing lines and the data lines by a predetermined level, providing a first touch sensing signal to each touch sensing line, and sensing a touch of a user based on signal variations of the touch sensing lines.
