摘要： The present disclosure provides an under-screen fingerprint recognition module, a display assembly and a display device. The under-screen fingerprint recognition module includes a base substrate and a plurality of fingerprint recognition units arranged on the base substrate. Each fingerprint recognition unit includes a photosensitive unit and an optical structure arranged on a photosensitive surface of the photosensitive unit. The optical structure includes a light-transmitting ring and a light-transmitting hole sequentially arranged in a direction away from the photosensitive unit. An orthogonal projection of the light-transmitting ring onto the photosensitive unit is completely located on the photosensitive surface of the photosensitive unit, and an orthogonal projection of the light-transmitting hole onto the light-transmitting ring is located within an opaque region surrounded by the light-transmitting ring.
