1. An array substrate, comprising:
a substrate;
a plurality of gate lines and a plurality of data lines positioned on the substrate, wherein the plurality of gate lines extend along a first direction and are arranged in a second direction different from the first direction, the plurality of data lines extend in the second direction and are arranged in the first direction, the plurality of gate lines intersect with the plurality of data lines to define a plurality of pixel areas; and
a plurality of touch signal lines positioned on the substrate, wherein the plurality of touch signal lines extend in the second direction, each of the plurality of touch signal lines comprises a lower touch signal line and an upper touch signal line, the lower touch signal line is positioned in a same layer as the plurality of data lines, the upper touch signal line is positioned above the lower touch signal line in a direction perpendicular to the array substrate;
wherein each touch signal line is adjacent to one of the plurality of data lines, the lower touch signal line comprises a first lower edge and a second lower edge extending along the second direction, a distance from the first lower edge to the adjacent data line in the first direction is less than a distance from the second lower edge to the adjacent data line in the first direction,
the upper touch signal line comprises a first upper edge and a second upper edge extending along the second direction, a distance from the first upper edge to the adjacent data line in the first direction is less than a distance from the second upper edge to the adjacent data line in the first direction, and
a distance from the second upper edge of the upper touch signal line to the adjacent data line in the first direction is less than a distance from the second lower edge of the lower touch signal line to the adjacent data line in the first direction.
