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.
