Abstract: An array substrate manufacturing method includes forming a plurality of first lead lines, a plurality of pixel electrodes, and a plurality of connecting lines over a substrate. Each first lead line is insulated from any pixel electrode, and each connecting line is insulated from any first lead line and is configured to electrically couple at least two pixel electrodes such that a set of pixel electrodes electrically coupled by each set of connecting lines substantially form an equivalent lead line. The method further includes detecting whether there is a short circuit between one equivalent lead line and a first lead line, and severing each of the plurality of connecting lines such that any two of the plurality of pixel electrodes are not electrically coupled.

Abstract: A display substrate includes: a base substrate including a photosensitive region, the photosensitive region including a plurality of display regions spaced apart and a gap region between the plurality of display regions; a first electrode layer on the base substrate; a light-emitting layer on a side of the first electrode layer away from the base substrate; and a second electrode layer on a side of the light-emitting layer away from the base substrate. Each display region corresponds to at least one first luminescent material region of the light-emitting layer; the gap region corresponds to the plurality of second luminescent material regions of the light-emitting layer; a part of the second electrode layer in the photosensitive region includes a plurality of second electrodes spaced apart, and an orthographic projection of each second electrode on the base substrate overlaps with each display region.
