Abstract: A display panel and a touch display device are disclosed herein. In one embodiment, the display panel includes data lines, gate lines, subpixels defined by the data lines and the gate lines, and touch sensors, and a touch sensing circuit sensing a touch or a touched position using the touch sensors. Each of the touch sensors is located on an encapsulation layer and comprises two or more sub-electrodes located on different layers, where the two or more sub-electrodes are electrically connected to each other.

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.

Abstract: Embodiments of the present disclosure relate to a touch display device, in which touch routing lines arranged in a non-active area do not overlap signal lines supplying a signal for driving a display, and in which the size of the area in which a connection electrode, which is positioned between the touch routing lines and the signal lines, overlaps the signal lines is reduced, thereby reducing direct and indirect noise due to the signal lines. In addition, the noise due to the signal lines can be dispersed through a shielding electrode by arranging the shielding electrode, to which a constant voltage is applied, in an opening in the connection electrode, thereby further reducing the noise of a touch sensing signal and improving touch sensing performance thereof.
