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.
