1. An array substrate, comprising a base substrate, and a plurality of gate lines extending in a first direction and a plurality of data lines extending in a second direction arranged on the base substrate, wherein each gate line crosses the plurality of data lines to define a plurality of sub-pixels, wherein the array substrate further comprises:
a plurality of touch signal lines extending in the second direction and arranged in light shielding regions of the sub-pixels;
a plurality of touch electrodes insulated from each other and each coupled to at least one touch signal line; and
a plurality of metal pattern units corresponding to the sub-pixels respectively and each arranged in the light shielding region of the corresponding sub-pixel,
wherein the metal pattern unit comprises a first metal strip arranged on at least one side of the data line and extending in the second direction, an overlapping area between an orthogonal projection of the first metal strip onto the base substrate and an orthogonal projection of the touch signal line onto the base substrate is A, and a ratio of the overlapping area A to an area of the orthogonal projection of the touch signal line onto the base substrate is greater than a threshold;
wherein the metal pattern unit further comprises a second metal strip, and the second metal strip comprises a first metal sub-line arranged on at least one side of the gate line and extending in the first direction, and a second metal sub-line arranged on at least one side of the data line and extending in the second direction, wherein the first metal sub-line is coupled to the second metal sub-line, and the second metal sub-line and the first metal strip are arranged at two opposite sides of the sub-pixel respectively.
