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: 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: In a touch display panel and a touch display device, a shielding pattern including the common electrode (COM) used as the touch electrode (TE) is disposed between a touch line (TL) and a data line (DL), and the touch line (TL) and the data line (DL) are arranged so as not to overlap each other in a boundary area between shielding patterns. The parasitic capacitance between the touch line (TL) and the data line (DL) can be reduced to improve the performance of touch sensing. In addition, the arrangement of the touch lines (TL) and data lines (DL) in the boundary area between shielding patterns is repeated at regular intervals to prevent an image abnormality.

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.
