Abstract: A touch display device is disclosed. By making at least one of a thickness or an angle of inclination of an insulating layer disposed on an area where a touch routing line is disposed on a non-active area of a display panel and an area that lacks the touch routing line to be different from each other, a short circuit between touch routing lines due to a defect in a process arranging the touch routing lines can be reduced.

Abstract: Embodiments of the present disclosure are related to a touch display device that includes a touch sensor. The touch sensor has a touch sensor structure that prevents or at least reduces a defect of a touch routing line that electrically connects a touch electrode and a touch pad. The defect is prevented or at least reduced due to a reduction of a height difference between a dam disposed between an active area and a pad area and a peripheral area thereof.

Abstract: Embodiments of the present disclosure are related to a touch display device, as a touch insulating film positioned under a touch electrode has a step difference and the touch electrode is disposed along a surface of the touch insulating film having the step difference. Thus, an area of the touch electrode disposed on an identical region increases and touch sensitivity can be improved. Furthermore, since the touch electrode is positioned lower toward from a central portion to an outer portion, a structure of the touch electrode being capable of improving touch sensitivity can be implemented without reducing a viewing angle of a light emitted from a light-emitting element positioned under the touch electrode.

Abstract: A touchscreen panel and a touch display device including the same are discussed. A plurality of touch lines disposed on the touchscreen panel include first touch lines and second touch lines. A portion or entirety of each of first touch lines connected to the first touch electrodes overlaps a corresponding one of second touch lines connected to the second touch electrodes. The degree of opening of the touchscreen panel is not lowered by the touch lines.

Abstract: A touch display device and a touch display panel are provided. The touch display panel includes a bend area adjacent to the periphery of the touch display panel, and touch lines disposed in the bend area have zigzag shapes that extend at angles with respect to a bend axis about which the bend area is bent. A first dielectric layer includes a compensation pattern that is located in the bend area and includes an opening that extends in a direction parallel to the bend axis. A second dielectric layer protrudes into the opening of the compensation pattern in a depth direction. During bending of the bend area, this configuration disperses force applied to portions of the touch lines and the dielectric layers in the bend area. This can consequently prevent both cracking due to bending and moisture permeation due to cracks.

Abstract: The present exemplary embodiments relate to a touch display device and a driving method thereof. A touch sensing time period is divided into a period when the touch is sensed by a self capacitive sensing manner and a period when the touch is sensed by a mutual capacitive sensing manner and a ground signal modulated to be the same as the touch driving signal is output to the display panel during the time period when the touch is sensed by the self capacitive sensing manner. By doing this, the parasitic capacitance in the display panel is reduced, sensitivity of touch sensing is improved, and various touch functions are provided.
