Abstract: A display device includes: a display region formed in a first region on a substrate and including a plurality of pixels arranged therein; a touch electrode disposed on the display region and configured to sense a touch; and a non-display region disposed in a second region on the substrate. The non-display region includes a first pad portion, a second pad portion, a link portion, and a wiring portion in which a wiring is disposed so as to interconnect the first and second pad portions and the link portion. The wiring portion is disposed in a bending region where the substrate is bent, and the wiring includes a first wiring and a second wiring formed above the first wiring and having at least one point connected to the first wiring in the bending region.

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.

Abstract: A touch display device and a touchscreen panel. Even in the case in which touch electrodes have different sizes or shapes or a located in different positions, a difference in capacitance is not formed among the touch electrodes. High touch sensitivity can be obtained. The touch display device comprises a plurality of touch electrodes, wherein a first touch electrode of the plurality of touch electrodes occupies a first area and comprises first mesh-shaped electrode metal. The touch display device comprises first dummy metal in a same layer as the first mesh-shaped electrode metal and in the first area occupied by the first touch electrode, the first dummy metal being electrically disconnected from the first mesh-shaped electrode metal.
