Abstract
A touch display device includes a shielding electrode disposed between a touch electrode and a signal line for driving the display. The shielding electrode enables a generation of a compensation voltage based on a feedback signal received from the shielding electrode. The compensation voltage compensates for noise on a voltage that is applied to the shielding electrode due to direct or indirect coupling between the signal line and the touch electrode. Thus, noise is, reduced in a touch sensing signal according to display driving, and improving the performance of touch sensing.
