An array substrate includes a plurality of sub-pixels and at least one light photosensitive detection assembly, and each photosensitive detection assembly corresponds to at least one sub-pixel. The at least one photosensitive detection assembly includes: a photosensitive element and a signal reading element coupled to the photosensitive element and a first reading signal line, the photosensitive element is configured to detect a luminance of a corresponding sub-pixel, and output a light detection signal according to the luminance of the corresponding sub-pixel. The signal reading element is configured to read the light detection signal output by the photosensitive element, and output a first detection signal to the first reading signal line according to the light detection signal.
