Abstract
A touch display device is disclosed that divides an active area into a reference touch area and a non-reference touch area and independently drives touch electrode lines positioned in the reference touch area and touch electrode lines positioned in the non-reference touch area. Touch sensing performance is enhanced while preventing or reducing signal distortion due to a difference in unit touch sensors in the reference touch area and the non-reference touch area.
