1. An array substrate, comprising a display area, a fanout area, and a connecting area located between the display area and the fanout area; wherein the array substrate further comprises:
a plurality of fanout lines located in the fanout area, wherein resistances of the plurality of fanout lines are different;
a plurality of signal lines located in the display area;
a plurality of connecting lines located in the connecting area, and electrically connected between the plurality of fanout lines and the plurality of signal lines; and
a plurality of coupling lines located in the connecting area, and disposed in different layers from the plurality of connecting lines;
wherein in a top view, the plurality of connecting lines partially overlap the plurality of coupling lines, overlapping areas between the plurality of connecting lines and the plurality of coupling lines are negatively correlated with the resistances of the plurality of fanout lines electrically connected to the plurality of connecting lines wherein the plurality of fanout lines comprise a first fanout line and a second fanout line, and a resistance of the first fanout line is greater than a resistance of the second fanout line; the plurality of signal lines comprise a first signal line and a second signal line; the plurality of connecting lines comprise a first connecting line and a second connecting line, the first connecting line is electrically connected between the first signal line and the first fanout line, and the second connecting line is electrically connected between the second signal line and the second fanout line; and wherein at least one of the plurality of coupling lines comprises a first routing part and a coupling part electrically connected to the first routing part, and a width of the first routing part is less than a width of the coupling part, and wherein in the top view, the first connecting line partially overlaps the first routing part, and the second connecting line partially overlaps the coupling part.
