Abstract: A touch display device is disclosed. The touch display device includes a touch electrode and a touch routing line that are disposed on an area that is different from an area where a spacer is disposed. Thus, a touch sensing function can be provided in the touch display device while reducing an influence that a touch sensor structure affects a viewing angle of an image.

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, 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 touch display device is disclosed. Since a touch electrode line included in the display device is divided into two or more touch electrode line parts connected to different touch routing lines, an entire load of the touch electrode line and the touch routing line can be reduced. As a portion of the touch routing line is disposed on an active area and touch routing lines connected to different touch electrode line parts are connected to each other between the active area and a touch driving circuit, an entire load can be reduced without an increase of a non-active area and an increase of a channel due to the touch routing lines, and a performance of a touch sensing can be improved.

Abstract: The disclosure is related to a touch display device, a shield electrode separated from a common electrode of a light-emitting element can be disposed on an area overlapping a touch electrode under an encapsulation layer, and a shield driving signal corresponding to a signal supplied to the touch electrode can be supplied to the shield electrode. Thus, the shield electrode prevents or at least reduces formation of a parasitic capacitance between an electrode or a signal line for a display driving and the touch electrode, and a touch detection performance can be improved by implementing a noise blocking function by the shield electrode.

Abstract: Aspects of the present disclosure relate to a touch display panel and a touch display device. In a structure in which a function module is disposed in an active area of a touch display panel, by providing a structure in which touch sensors or touch lines adjacent to the function module are connected through a connecting pattern disposed outside the function module or a sensor connection line disposed in a bezel area of the function module, it is possible to provide a touch sensing function throughout the entire area where images are displayed in a structure including an area, where images are not displayed, such as a function module in an active area.

Abstract: Embodiments of the present disclosure relate to a touch panel and a touch display panel, wherein touch electrodes including bodies and wings are arranged so as to interlock with each other to thus reduce a difference in sensing sensitivity depending on position and a movement direction, thereby improving uniformity of touch sensing. In addition, the body and wing of the touch electrode can be arranged so as to be varied in length/width depending on the position thereof, so that the boundary area between the touch electrodes is increased, thereby improving the intensity of a touch-sensing signal, and so that sensing time is reduced, thereby enhancing the performance of touch sensing.
