1. An array substrate, comprising:
a base substrate comprising a first surface and a second surface opposite to the first surface, wherein the base substrate comprises a display region and a peripheral region surrounding the display region, the peripheral region comprises a first peripheral region surrounding the display region and a second peripheral region surrounding the first peripheral region;
a plurality of pixel units located on the second surface of the base substrate, wherein orthographic projections of the plurality of pixel units on the base substrate are located in the display region and distributed in an array, and at least one of the plurality of pixel units comprises a common electrode;
a light shielding layer located on the first surface of the base substrate, wherein an orthographic projection of the light shielding layer on the base substrate is located in the peripheral region, and at least part of the orthographic projection of the light shielding layer on the base substrate is located in the second peripheral region; and
a first common electrode bus located on the second surface of the base substrate, wherein an orthographic projection of the first common electrode bus on the base substrate is located at least partially in the second peripheral region, and the first common electrode bus is electrically connected to the common electrode,
wherein a material of the first common electrode bus comprises a metal material, and a distribution density of the first common electrode bus in the first peripheral region is less than a distribution density of the first common electrode bus in the second peripheral region;
wherein an orthographic projection of a boundary of the first common electrode bus close to the display region on the base substrate is located at a junction of the first peripheral region and the second peripheral region; and
wherein the orthographic projection of the boundary of the first common electrode bus close to the display region on the base substrate is located in the orthographic projection of the light shielding layer on the base substrate.
