    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 provides 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: A touch sensing device comprises a common electrode divided into a plurality of sensor electrodes, a plurality of sensor lines respectively connected to the plurality of sensor electrodes, a feedback voltage transmitter, and a common voltage compensator. The feedback voltage transmitter includes a feedback line, a plurality of switching elements configured to selectively connect the sensor lines to the feedback line, and a feedback control line configured to control selection of the switching elements. The common voltage compensator is configured to receive a feedback voltage supplied to the sensor lines through the feedback line while the sensor lines are connected to the feedback line through the plurality of switching elements, and compensate the feedback voltage to a reference voltage level.
