Abstract: The present disclosure relates to display assemblies, display apparatus, and driving methods. One example display assembly includes a display panel and a function module located on a light-emitting surface of the display panel. A function unit in the function module 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 active layer is located on a side of the first gate away from the display panel. 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 function unit includes a transparent electrode located on the first active layer and overlapping the first active layer.
