    Abstract: A disclosed touchscreen display device includes a display panel with data lines, gate lines, and N×M subpixels arranged in a matrix of N subpixel rows and M subpixel columns, and respectively connected to the corresponding data lines and the corresponding gate lines, where N and M are each a natural number greater than or equal to 2. The display device also includes touch electrodes. The display device is configured to provide a scanning signal to the gate lines connected to the N subpixel rows in a first sequence during an ith frame and in a second sequence different from the first sequence during an (i+1)th frame, where i is a positive integer. Each of the ith frame and the (i+1)th frame is configured to include at least one display driving mode section and at least one touch driving mode section.

    Abstract: The disclosure is related to a touch display device, a shield electrode separated from a common electrode of a light-emitting element can be disposed on an area overlapping a touch electrode under an encapsulation layer, and a shield driving signal corresponding to a signal supplied to the touch electrode can be supplied to the shield electrode. Thus, the shield electrode prevents or at least reduces formation of a parasitic capacitance between an electrode or a signal line for a display driving and the touch electrode, and a touch detection performance can be improved by implementing a noise blocking function by the shield electrode.
