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: 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: Embodiments of the present disclosure are related to a touch display device that includes a touch sensor. The touch sensor has a touch sensor structure that prevents or at least reduces a defect of a touch routing line that electrically connects a touch electrode and a touch pad. The defect is prevented or at least reduced due to a reduction of a height difference between a dam disposed between an active area and a pad area and a peripheral area thereof.
