Abstract: The present embodiments relate to a driving circuit and a touch display apparatus for sensing a user's touch position and touch force with respect to a display panel, and further relate to a driving method thereof. The touch display apparatus may include a plurality of first electrodes that are configured to be embedded in a display panel, and a second electrode that is configured to be positioned outside the display panel. The touch display apparatus may read a force sensing signal from the second electrode through a signal detecting unit that is electrically connected to the second electrode. Therefore, it is possible to sense a touch force without separating a force sensing signal from a signal received from the first electrode, and to sense a user's touch force through the driving of the second electrode regardless of the driving mode of the first electrode.

Abstract: In a touch display panel and a touch display device, a shielding pattern including the common electrode (COM) used as the touch electrode (TE) is disposed between a touch line (TL) and a data line (DL), and the touch line (TL) and the data line (DL) are arranged so as not to overlap each other in a boundary area between shielding patterns. The parasitic capacitance between the touch line (TL) and the data line (DL) can be reduced to improve the performance of touch sensing. In addition, the arrangement of the touch lines (TL) and data lines (DL) in the boundary area between shielding patterns is repeated at regular intervals to prevent an image abnormality.
