Zusammenfassung:The invention provides a capacitance touch display device including a capacitance touch control panel and a capacitance touch con trol sensor. The capacitance touch control sensor includes a plurality of driving lines, a plurality of sensing lines and a sensing circuit. At a certain time point, the first driving line and the second driving line arranged in alternate permutation are used for inputting first driving voltage and second driving voltage with different phase and voltage. A first node is form by overlapping the first sensing line with the first driving line and does not overlap with the second driving line. The second sensing line overlaps with the second driving line, so that a second node is formed and does not overlap with the first driving line. A first mutually-inducting capacitance and a second mutually-inducting capacitance are formed by coupling the first node with the second node, and a first sensing voltage and a second sensing voltage are formed and are output by the first sensing line an
