Abstract

The invention provides a fingerprint acquisition module, a display apparatus, and a fingerprint recognition method. The fingerprint acquisition module comprises a photosensitive element and an optical modulation film located at one side of a photosurface of the photosensitive element, the optical modulation film comprises a micro-lens array and a light shielding layer with a plurality of optical apertures, the light shielding layer is located between the photosensitive element and the micro-lens array, and the plurality of optical apertures and micro-lenses in the micro-lens array are arranged in a one-to-one correspondence manner. By employing the fingerprint acquisition module, the image definition of acquired fingerprint images can be improved, and the rate and the accuracy of fingerprint recognition can be improved.

Description

Technical field [0001] The present invention relates to the technical field of fingerprint collection, in particular to a fingerprint collection module, a display device and a fingerprint identification method. Background technique [0002] At present, display devices with fingerprint collection modules have attracted more and more attention. The fingerprint collection modules in existing display devices are usually provided with a light shielding layer with small holes on the side of the photosensitive surface of the photosensitive element. The received light beam is focused and imaged onto the photosensitive surface of the photosensitive element. However, the image clarity of the fingerprint image collected by the aforementioned fingerprint collection module is indeed difficult to meet the expected requirements, which affects the rate and accuracy of fingerprint recognition. Summary of the invention [0003] In view of this, the present invention provides a fingerprint acquisit...
