Abstract: A touchscreen panel and a touch display device including the same are discussed. A plurality of touch lines disposed on the touchscreen panel include first touch lines and second touch lines. A portion or entirety of each of first touch lines connected to the first touch electrodes overlaps a corresponding one of second touch lines connected to the second touch electrodes. The degree of opening of the touchscreen panel is not lowered by the touch lines.

Abstract: Discussed are a touch display panel, a touch display device, and a driving method thereof, wherein a constant voltage is applied to a cathode electrode during a period for sensing a finger touch or a pen touch, thereby performing touch sensing while performing display driving. In addition, a signal having the same phase and potential as the signal applied to the touch electrode is applied to the cathode electrode during a period for transmitting an uplink signal to the pen, thereby eliminating parasitic capacitance between the touch electrode and the cathode electrode, preventing transmission delay of the uplink signal, improving the recognition rate of the uplink signal, and enhancing the performance of pen-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.
