Zusammenfassung:	A touch display device (100, figure 1) comprises a display panel (110, figure 1) having plural touch electrodes TE arranged into plural touch blocks TB each including a respective portion of the plurality of touch electrodes TE. A plurality of touch block lines TBL connect to respective touch blocks TB and a plurality of touch electrode lines TEL connect to respective touch electrodes TE. A touch driving circuit (150, figure 1) senses touch of a touch block TB based on a first touch signal received from a touch block line TBL and senses touch of a touch electrode TE, from the plurality of touch electrodes TE included in the touch block TB, based on a second touch signal received from a touch electrode line TEL that is connected to the touch electrode. A touch block detection element TDDL may be disposed at least partially around the plurality of touch electrodes included in a touch block TB.
