1. A display panel, comprising:
a display area comprising a touch electrode array; and
a non-display area enclosing the display area;
wherein the touch electrode array comprises a plurality of touch electrodes and a plurality of touch signal wires, and wherein one touch electrode is electrically connected to at least one touch signal wire;
wherein the non-display area comprises at least two fan-out routing areas, wherein the at least two fan-out routing areas are arranged along a first boundary between the non-display area and the display area, wherein each fan-out routing area comprises a plurality of touch leading wires, and wherein the touch leading wires are electrically connected to the touch signal wires in a one-to-one correspondence;
wherein each fan-out routing area comprises a fan-shaped area and a straight line area, and wherein the fan-shaped area is located between the first boundary and the straight line area;
wherein each touch leading wire comprises a first sub-leading wire connected to a second sub-leading wire, wherein the first sub-leading wire is located in the fan-shaped area, and wherein the second sub-leading wire is located in the straight line area;
wherein a distance between two second sub-leading wires that are adjacent and that are located in different straight line areas is a first distance, a distance between two second sub-leading wires that are adjacent and that are located in a same straight line area is a second distance, and the first distance is greater than the second distance;
wherein at least some of the plurality of touch signal wires are jump touch signal wires, wherein a shape of each of the jump touch signal wires is a fold line, wherein each of the jump touch signal wires comprises a start point and an end point, wherein the start point is electrically connected to one touch electrode, and wherein the end point intersects the first boundary; and
wherein a distance between the start point and a central axis is a third distance, wherein a distance between the end point and the central axis is a fourth distance, and wherein the third distance is greater than the fourth distance.
