Abstract: Disclosed is a touch sensitive display apparatus which decreases a load of each of a plurality of touch electrodes and reduces a load deviation between the plurality of touch electrodes, thereby enhancing image quality. The touch sensitive display apparatus comprises a touch sensitive panel. The touch panel comprises a plurality of touch electrodes comprising at least a first touch electrode. The first touch electrode comprises a plurality of first touch electrode lines that are parallel to each other. A first touch signal line is connected to the plurality of first touch electrode lines of the first touch electrode, and the first touch electrode is driven for image display and touch sensing via the first touch signal line. A first connecting line is in a different layer than the first touch electrode lines, and the first connecting line is connected to the plurality of first touch electrode lines.

Abstract: A display device with integrated touch screen is provided. The display device may include a panel and a touch IC. The panel may include a plurality of driving electrodes and sensing electrodes. The touch IC may compensate for a feedback common voltage outputted from the panel by generating a compensation common voltage based on the feedback common voltage and applying the compensation common voltage to the driving electrodes and the sensing electrodes when the panel operates in a display driving mode.
