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 exemplary embodiments relate to a touch display device and a driving method thereof. A touch sensing time period is divided into a period when the touch is sensed by a self capacitive sensing manner and a period when the touch is sensed by a mutual capacitive sensing manner and a ground signal modulated to be the same as the touch driving signal is output to the display panel during the time period when the touch is sensed by the self capacitive sensing manner. By doing this, the parasitic capacitance in the display panel is reduced, sensitivity of touch sensing is improved, and various touch functions are provided.
