The present disclosure relates to display assemblies, display apparatuses, and fingerprint recognition methods. One example display assembly includes a display panel and a fingerprint recognition module located on a light-emitting surface of the display panel. The fingerprint recognition module includes multiple fingerprint recognition units. Each fingerprint recognition unit includes at least one phototransistor and one switch transistor. The phototransistor includes a first active layer, a first gate, a first source, and a first drain. A material for making the first active layer includes an organic semiconductor material. The first drain and the first gate partially overlap to form a first capacitor. The switch transistor includes a second active layer, a second gate, a second source, and a second drain. The fingerprint recognition module includes a first metal layer. The first source, the first drain, the second source, and the second drain are all located at the first metal layer.
