1. A touch display panel comprising:
- a touch electrode, comprising a plurality of electrode pairs arranged in rows and columns to form an array, wherein each electrode pair of the plurality of electrode pairs comprises a first electrode block and a second electrode block insulated from each other, and the first electrode block encompasses the second electrode block as a homocentric square;
a plurality of first signal lines located in a conducting layer, wherein the conducting layer comprises a plurality of dummy wires; and
a plurality of second signal lines connected to a same second signal bus;
wherein both the plurality of first signal lines and the plurality of second signal lines are arranged along the column direction;
wherein in one column of the array, each first electrode block connects to one of the plurality of first signal lines in a one-to-one association, each second electrode block connects to a same second signal line;
wherein in one column of the array, each first electrode block overlays but insulates from a corresponding second signal line in the same column; and
wherein the second electrode blocks are formed from the plurality of dummy wires.
