Touch display panel

A touch display panel, comprising:

• a touch electrode wiring layer, wherein the touch electrode wiring layer comprises a plurality of touch electrodes, and the plurality of touch electrodes are arranged in an array;
• and
• a signal transmission wiring layer, wherein the signal transmission wiring layer is arranged on one side of the touch electrode wiring layer, the signal transmission wiring layer comprises a plurality of signal transmission line groups, and the plurality of signal transmission line groups and the plurality of touch electrodes are electrically connected in one-to-one correspondence;
• wherein each group of the plurality of signal transmission line groups comprises at least two of the signal transmission lines, the at least two of the signal transmission lines are arranged at intervals, and the at least two of the signal transmission lines in each group of the signal transmission line groups are electrically connected with the corresponding touch electrodes;
• wherein the signal transmission line group further comprises a first connection line, the first connection line is disposed between the adjacent signal transmission lines, and the first connection line overlaps the plurality of the touch electrodes;
• and
• wherein the signal transmission line group further comprises a second connection line, the second connection line is disposed between the adjacent signal transmission lines, and an orthographic projection of the second connection line on the touch electrode wiring layer is located between the adjacent touch electrodes.
