Abstract: Embodiments of the present disclosure are related to a touch display device, as a portion of a touch routing line is disposed on an area surrounded by a touch electrode line on an active area and is electrically connected to the touch electrode line, the touch routing line can be disposed on the active area while reducing an influence of a noise. Thus, as an additional arrangement of the touch routing line and a free adjustment of a connecting point of the touch routing line become possible without an increase of an area for arranging the touch routing line, a load by the touch routing line and a difference of a sensitivity according to positions of the touch electrode line are reduced and a performance of a touch sensing can be improved.

Abstract: The present disclosure relates to a touch display device, and more specifically, relates to a touch display device having a bottom emission structure. According to the touch display device, by disposing a touch electrode and a touch planarization layer between a substrate and a thin film transistor, a touch sensing function can be implemented without affecting the disposing of components for display driving. Further, by disposing a shielding electrode to which a constant voltage or a signal equal to a touch driving signal is applied between the touch electrode and a light emitting element, a noise of a touch sensing signal caused by display driving can be reduced and the performance of touch sensing performed together with the display driving can be improved.

Abstract: Provided is a touch display device including a folding area in an active area. The same pattern of touch electrodes can be maintained in both a reference area and a folding area and cracks on touch electrodes in the folding area, by applying a pattern structure of a touch insulation film disposed in the folding area. Therefore, the degradation of touch sensing performance, caused by cracks on the touch electrodes in the folding area, can be prevented and touch sensing sensitivity can be uniform in the reference area and the folding area, thereby improving touch sensing performance of the touch display device including the folding area.

Abstract: Provided is a touch display device. Because a shielding electrode, which is disposed in a non-active area and electrically coupled between a common electrode and a common voltage supply line, is located between a touch routing line and a signal line, the effects of noise caused by the signal line on the touch routing line may be reduced. Further, an encapsulation portion located on the shielding electrode has a planarized structure. The resulting maintenance of a certain distance between the shielding electrode and the touch routing line may reduce noise caused by the signal line from indirectly affecting the touch routing line through the shielding electrode.

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.

Abstract: The present disclosure relates to a touch display device including a substrate, a pixel area in which at least one subpixel is disposed, a first touch sensor area located on a first side of the pixel area, a second touch sensor area located on a second opposing side of the pixel area, at least one pixel electrode disposed in the pixel area, a first electrode disposed in the first touch sensor area, and a second electrode disposed in the second touch sensor area. As the first electrode and the second electrode include a metal included in the at least one pixel electrode, the touch display device can provide an effect of reducing the thickness of a display panel even though a touch sensor is embedded in the display panel.

Abstract: Embodiments of the present disclosure are related to a touch display device, as a plurality of first line parts disposed on a first sensor layer and a plurality of second line parts disposed on a second sensor layer are alternated to make a touch line, at least a portion of different touch lines can be disposed to be overlapped each other, thus a plurality of touch lines can be disposed while reducing or minimizing a reduction of an aperture ratio or a transmittance of a subpixel due to an arrangement of the touch line. Accordingly, a touch sensitivity can be enhanced by further disposing touch electrodes, or the touch display device having a large area with many channels can be implemented easily by further disposing touch lines.

Abstract: Embodiments of the present disclosure relate to a touch sensing unit and a touch display device, in which touch routing lines can be arranged so as not to overlap signal lines supplying a signal for driving a display and the area of an electrode located between the signal line and in which the touch routing line can be reduced, thereby reducing parasitic capacitance between the signal line and the touch routing line. In addition, it is possible to further reduce noise due to the signal lines and to improve the performance of touch sensing by distributing noise due to the signal lines through touch dummy electrodes positioned between the touch electrodes and the touch routing lines so as to overlap the signal lines.
