摘要： Disclosed by the embodiment of the present disclosure is a display device, wherein a collimation structure is formed by a first imaging aperture in a pixel defining layer and a second imaging aperture in a light shielding layer, the first imaging aperture and the second imaging aperture may screen out light rays reflected by a fingerprint in a nearly collimated manner so that the light rays may reach a fingerprint recognition component below, the fingerprint recognition component may detect and read intensities of the light rays, and the intensities of the light rays detected by the fingerprint recognition component are different because of different energies of the light rays transmitted downward from the valley and the ridge of the fingerprint, thereby acquiring fingerprint information and achieving fingerprint recognition. Moreover, the fingerprint recognition component is integrated in a display area to achieve large-area fingerprint recognition.
