Abstract
Disclosed are a display substrate and a display apparatus. The display substrate includes the photosensitive devices, a noise reduction layer, the light-emitting devices and a black matrix are sequentially arranged, where the black matrix does not shield the light-emitting devices, the black matrix includes the first openings, which are located in at least some gaps of the light-emitting devices and correspond to the photosensitive devices, and an orthographic projection of each first opening is located in an orthographic projection of each photosensitive device; an orthographic projection of the noise reduction layer at least overlaps with orthographic projections of the photosensitive devices, and the noise reduction layer is provided with the second openings, orthographic projections of which are located in the orthographic projections of the photosensitive devices; and each photosensitive device, each first opening and each second opening satisfy the following relational expressions: d=X*D, D=K*D, and d=D−(D+D)*h/(h+h+h).
