Accordingly, it can expand the frequency band of the ultrasonic waves generated by the ultrasonic sensor to improve its sensing performance, and obtain information of various frequency bands to provide the ultrasonic sensor capable of both the fingerprint sensing and the proximity sensing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasonic sensor and display device","description":"An ultrasonic sensor and a display device is disclosed where a piezoelectric material disposed in each pixel area of the ultrasonic sensor is formed to have various thicknesses, or an electrode drivin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11249599","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.
