Abstract

Disclosed are a display module and an electronic device. The display module includes a photosensitive region and a non-photosensitive region located on at least one side of the photosensitive region. The display module further includes a light-emitting element located in the photosensitive region and the non-photosensitive region, a light-shielding layer located at the photosensitive region and the non-photosensitive region and at a light-exiting side of the light-emitting element, and a light-guiding layer at least located at the photosensitive region and at a side of the light-emitting element facing away from the light-shielding layer. The light-guiding layer includes light-guiding openings, the light-shielding layer includes first light-shielding openings located in the photosensitive region and second light-shielding openings located in the non-photosensitive region, and the first light-shielding openings at least partially overlap the light-guiding openings along a thickness direction of the display module.
