Abstract
A display substrate includes a base substrate including a display region and a peripheral region located on at least one side of the display region. The display region is provided with a plurality of sub-pixels, and at least one of the plurality of sub-pixels includes a light-emitting element and a pixel circuit for driving the light-emitting element. The peripheral region includes a detection region, and the detection region is provided with at least one detection electrode which is electrically connected with a first electrode of the light-emitting element and the pixel circuit through a detection lead wire, to detect electrical performance of the light-emitting element through the detection electrode in a detection stage.
