Array substrate and preparation method therefor, and display panel and display device

The present disclosure relates to the technical field of display. Disclosed are an array substrate and a preparation method therefor, and a display panel and a display device. The array substrate includes: a substrate; multiple gate lines, wherein the gate lines are located on the substrate, and extend along a first direction; multiple data lines, wherein the data lines are located on the substrate, and extend along a second direction, and the gate lines and the data lines intersect to define multiple pixel areas; and a touch-control electrode wiring wherein the touch-control electrode wiring has the same direction as that of the gate lines, and is arranged insulated from the gate lines on a different layer, and the orthographic projection of the touch-control electrode wiring on the substrate at least has an overlapping area with the orthographic projection of part of the gate lines on the substrate.
