1. A touch display panel, comprising:
a plurality of touch electrode sets, wherein each of the touch electrode sets comprises a plurality of touch electrodes disposed insulatively;
a plurality of touch wires, wherein adjacent two of the touch wires are disposed insulatively from each other, one of the touch wires corresponds to one of the touch electrode sets, and is connected to one of the touch electrodes in a corresponding one of the touch electrode sets; and
at least one repair line, wherein the repair line is disposed insulatively from the touch wires, the repair line comprises a repair section and a connection section electrically connected to each other, and an extension direction of the connection section is the same as an extension direction of the touch wires;
wherein the repair section corresponds to at least one of the touch wires, and an orthographic projection of the touch wire corresponding to the repair section on the touch display panel partially coincides with an orthographic projection of the repair section on the touch display panel;
wherein the touch display panel comprises a displaying region and a non-displaying region surrounding the displaying region;
the touch electrode sets are located in the displaying region, the touch electrode sets are disposed along a first direction, and the touch electrodes in each of the touch electrode sets are disposed along a second direction;
the extension directions of the touch wires and the connection section are parallel to the second direction, and a first end of the connection section and a first end of the touch wires extend along the second direction from the displaying region to the non-displaying region;
an orthographic projection of the touch wires on a corresponding one of the touch electrode sets coincides with each of the touch electrodes of the corresponding one of the touch electrode sets; and
the repair section is located in the non-displaying region, and an orthographic projection of some of the touch wires located in the non-displaying region on the touch display panel partially coincides with the orthographic projection of the repair section on the touch display panel;
wherein the touch display panel comprises an underlay, a first metal layer located on the underlay, an insulation layer located on the first metal layer, and a second metal layer located on the insulation layer; the touch wires are located on the first metal layer, and the touch electrodes are located on the second metal layer; and
wherein a plurality of first via holes are defined in the insulation layer, and each of the touch wires is electrically connected to one of the touch electrodes in the touch electrode sets through one of the first via holes.
