Abstract: In a touch display device, a controller generates a touch sync signal for controlling timing of a touch sensing period and a display period in each of a plurality of frames. A touch panel has a plurality of touch electrodes in a display area to generate touch sensing signals indicating whether or not a touch occurs during the touch sensing period. A touch sensing circuit supplies a touch drive signal to the plurality of touch electrodes during the touch sensing period and detects if the touch occurred based on the touch sensing signals received from the plurality of touch electrodes. A touch assistance line surrounds the display area and is disposed in the non-display area of the touch panel. A touch assistance signal supply circuit generates a touch assistance signal on the touch assistance line. The touch assistance signal mimics the touch drive signal during the touch sensing period.

Abstract: The display device includes a panel comprising driving electrodes and receiving electrodes, and a touch sensing unit comprising a driver supplying a common voltage to the driving electrodes and the receiving electrodes during an image display period, and sequentially supplying a driving voltage to the driving electrodes to determine whether the panel is touched, during a touch sensing period, and a receiver determining whether there is a touch on the panel based on comparison of a sensing signal induced through the receiving electrodes by the driving voltage with a reference voltage applied to the receiving electrodes. The reference voltage is different from an intermediate level of the driving voltage corresponding to an average of a maximum level and a minimum level of the driving voltage. A root mean square value of the reference voltage is substantially equal to a root mean square value of the driving voltage.
