Abstract
Provided are a display module and a display apparatus. The display module includes: sub-pixels arranged in an array along a first direction and a second direction; and an array substrate including an underlay substrate, a fingerprint recognition unit, and a first light-shielding layer. The fingerprint recognition unit includes a photosensitive semiconductor layer, and an orthographic projection of the photosensitive semiconductor layer on a plane of the underlay substrate is located between two adjacent sub-pixels along the second direction. The first light-shielding layer is located on a side of the photosensitive semiconductor layer close to the underlay substrate, and an orthographic projection of the first light-shielding layer on a plane of the photosensitive semiconductor layer completely covers the photosensitive semiconductor layer, and along the first direction, a length of the first light-shielding layer is larger than or equal to twice a length of each of the plurality of sub-pixels.
