  • Patent number: 10871845
    Abstract: Disclosed are a touch display panel and a touch display device. In a touch display panel and a touch display device, a shielding pattern is arranged between a data link line and a touch link line in a non-active area of the touch display panel, and a signal corresponding to the touch driving signal is applied to the shielding pattern. Parasitic capacitance between the data link line and the touch link line is prevented in order to reduce noise on the touch sensing signal caused by voltage fluctuation on the data link line. Accordingly, it is possible to reduce the influence of display driving on touch sensing, thereby improving touch sensing during display driving.

  • Patent number: 10860128
    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.
