The fingerprint recognition method of the present invention includes: the oscillator receiving the clock signal and outputting the oscillation frequency signal; a finger touching the plurality of sensing finger touch pads; and counting and comparing the oscillation frequency signal and the oscillation frequency signal after the touch. The present invention is applied to the display surface of the electronic product, and detects whether the finger touches the fingerprint recognition device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint recognition device and fingerprint recognition method thereof","description":"The fingerprint recognition device of the present invention includes: a substrate; a sensor located on the substrate and the sensor including a plurality of sensing finger touch pads around thereof; a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11474650","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.
