Abstract: In a touch display device with a touch sensor structure in which two or more touch electrodes located in two or more subareas are electrically connected to each other via one touch line, itis possible to decrease the number of touch channels. With a touch sensor structure in which two or more touch electrodes are connected to each touch line in a touch electrode connecting structure capable of removing ghost data, it is possible to improve touch sensitivity greatly.

Abstract: A touch display panel and device. A common electrode is provided between a display driving signal line and a touch line. The common electrode functions as a shielding pattern that prevents display noise of a touch sensing signal without increasing the number of masks used to form the touch display device. A touch load reducing layer is disposed in a region between the touch line and the common electrode, except for a region in which the common electrode and pixel electrodes overlap. This reduces the load of the touch line and improves touch sensing performance without having an adverse effect on display driving.
