Abstract:
At least one embodiment of this disclosure provides a display apparatus for solving the problem of a low identification precision due to a relatively large distance between the finger and the fingerprint identification device. The display apparatus comprises a display panel and at least one fingerprint identification device. Each fingerprint identification device comprises a plurality of identification units arranged in an array, each identification unit being provided with a photosensitive element. The photosensitive element is used for performing photoelectric conversion of incident light. The fingerprint identification device further comprises a collimating filter layer arranged on a light entrance surface of the photosensitive element. The collimating filter layer comprises a plurality of strip-shaped light guide portions arranged to be spaced and parallel, a longitudinal direction of the plurality of strip-shaped light guide portions being substantially perpendicular to the light entrance surface of the photosensitive element.
