Touch display panel, touching display device having reduced signal interferences and driving method thereof

A touch display panel comprising a first substrate and a second substrate aligned with each other, wherein the touch display panel further comprises:

• a first signal transmission line and a second signal transmission line arranged on the first substrate, the second signal transmission line intersecting with the first signal transmission line;
• gate lines and data lines arranged on the second substrate, the second substrate being further provided with a first signal output end and a second signal output end arranged alternately, the first signal output end and the second signal output end being electrically connected with the gate lines;
• and
• a first spacer corresponding to the first signal transmission line and a second spacer corresponding to the second signal transmission line, the first spacer being used for achieving electrical connection between the first signal transmission line and the first signal output end when a corresponding touch region is in a touch state, and the second spacer being used for achieving electrical connection between the second signal transmission line and the second signal output end when the corresponding touch region is in a touch state,
• wherein a first insulating layer is further provided on the first signal transmission line and the second signal transmission line, and via holes penetrating the first insulating layer and corresponding to the first signal transmission line and the second signal transmission line respectively are filled with an electrically conductive material, to achieve electrical connections between the first spacer and the first signal transmission line, as well as between the second spacer and the second signal transmission line respectively.
