Abstract: Embodiments of the disclosure may insert a break period when the gate line is not driven, such as a blank period, of an active period of a frame period and perform touch sensing, driven in the same manner as touch sensing driven in the blank period, in the break period, thereby reducing the influence of display driving on touch sensing and enhancing touch sensing performance.

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.

Abstract: The present disclosure is directed to a touch display device that is capable of reducing a load of a touch sensor structure disposed in a display panel and improving the accuracy of touch sensing capabilities of the touch display device. In one aspect, touch electrode lines disposed on an active area are disposed to be separated into a plurality of sub-areas. A number of touch routing lines connected to the touch electrode lines are disposed on the active area, thus a touch sensor structure with a reduced load can be provided while minimizing an increase of a non-active area due to an arrangement of the touch routing lines.
