An array substrate including: a substrate; a data line on the base substrate and extending in a first direction; and a touch signal line on the base substrate, wherein an extending direction of the touch signal line is the same as an extending direction of the data line; the data line and the touch signal line are in different layers and insulated from each other, and an orthographic projection of the touch signal line on the base substrate at least partially overlaps an orthographic projection of the data line on the base substrate.
