Each recognizer unit includes: a first optical grating which is between the light guiding layer and the light transmission substrate and is configured to diffractively couple a fingerprint light ray having an incident angle within a preset angle range to the light guiding layer; a second optical grating on a side of the light guiding layer; and a detector module on a side of the second optical grating away from the light guiding layer. The second optical grating is configured to extract the fingerprint light ray in the light guiding layer to the detector module, and the detector module is configured to detect a light intensity of the fingerprint light ray."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint recognition device, recognition device and display device","description":"A fingerprint recognition device, a recognition device and a display device are provided to include: a light guiding layer and a plurality of recognizer units, on a side of a light transmission substr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11308308","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
