    Abstract: The present exemplary embodiments provide a touch display device which connects a touch driving circuit and a plurality of touch sensors using a plurality of dummy pixels disposed on a display panel to recognize touch event of a user. When the touch wiring line is implemented, the same material as the pixel electrode or the source line included in the plurality of dummy pixels is used so that a separate process for implementing the touch wiring line is not necessary. Further, in a pixel structure in which one data line is disposed for every two pixels, the source line is disposed in a region where the data line is not disposed to be used as a touch wiring line. Therefore, the touch recognizable area may expand as compared with a case using a pixel metal.

    Abstract: Embodiments of the disclosure may provide a touch display device in which in a structure in which touch electrodes are separately disposed in a first sub area and a second sub area of an active area, X-touch electrodes disposed in the first sub area and the second sub area are electrically connected with each other, and Y-touch electrodes are electrically separated from each other. It is possible to reduce the load by a structure in which touch electrodes are divided for each sub area and to reduce the number of channels by driving the X-touch electrodes in the first sub area and second sub area by the same number of channels.

    Abstract: A touch display device and a touchscreen panel. Even in the case in which touch electrodes have different sizes or shapes or a located in different positions, a difference in capacitance is not formed among the touch electrodes. High touch sensitivity can be obtained. The touch display device comprises a plurality of touch electrodes, wherein a first touch electrode of the plurality of touch electrodes occupies a first area and comprises first mesh-shaped electrode metal. The touch display device comprises first dummy metal in a same layer as the first mesh-shaped electrode metal and in the first area occupied by the first touch electrode, the first dummy metal being electrically disconnected from the first mesh-shaped electrode metal.

    Abstract: The present embodiments generally relate to a display panel and a display device which may recognize touch. A display panel is provided in which a touch sensor and a touch line are disposed in an active area in which a part of an outer edge of the touch line is curved to correspond to a curved shape of the active area in the display panel so that the touch sensing is allowed in display panels having various shapes. Further, a touch display device is provided in which an open area is located between two adjacent touch lines disposed on the display panel so that touch sensing is allowed also in the display panel including an open area such as a hole or a notch.

    Abstract: An embodiment disclosed herein provides a sensing unit that senses a touch corresponding to a capacitance formed by a first electrode and a second electrode. The first electrode includes a first driving electrode pattern and a first sensing electrode pattern, the first sensing electrode pattern being disposed in the first driving electrode pattern, the second electrode includes a second driving electrode pattern and a second sensing electrode pattern, the second driving electrode pattern being disposed in the second sensing electrode pattern. A first capacitive coupling is formed corresponding to the first touch electrode and the first sensing electrode, a second capacitive coupling is formed corresponding to the second driving electrode and the second sensing electrode, and a third capacitive coupling is formed corresponding to the first touch electrode and the second sensing electrode.
