    Abstract: A touch sensor integrated type display device includes a display panel. The display panel includes a multiplexing unit that supplies a common voltage to touch/common electrodes of the display panel during a display driving period of one frame period of the display panel to display an image on the display panel. The multiplexing unit senses the touch/common electrodes using a self-capacitive method during a first touch driving period of the one frame period and a mutual capacitive method during a second touch driving period of the one frame period of the display panel to sense touch of the display panel.

    Abstract: Embodiments of the present disclosure relate to a touch display device and, more particularly, to a touch display device including a touch panel that can reduce the number of signal lines and the number of touch channels and can prevent or reduce a ghost phenomenon in multi-touching. In particular, the touch display device includes a woven type touch panel in which touch electrodes are formed by disposing electrodes to be entangled and electrically connecting the entangled electrodes such that electrically disconnected points exist, thereby being able to reduce the number of signal lines and the number of touch channels and prevent or reduce a ghost phenomenon in multi-touching.
