Abstract
Disclosed are a display panel and an electronic device. In a fingerprint recognition stage, at least one of the first and second organic light-emitting structures function as a light source of the fingerprint recognition unit; the emergent light of the at least one of the first and second organic light-emitting structures has a first spectral range, the transmission spectral range of the first color filter film is a second spectral range, and the spectral range corresponding to visible light and near-infrared light is a third spectral range. The first spectral range is located within the second spectral range which is located within the third spectral range, light from at least a part of the wave band located within the third spectral range and outside the second spectral range is absorbed or reflected by the first color filter film.
