The substrate has power lines and signal lines. The piezoelectric pillars are electrically isolated from each other, and each of the piezoelectric pillars includes a piezoelectric material that generates an electric voltage across a pair of the signal lines responsive to an applied touch force compressing the piezoelectric pillar. The light emitter devices are each electrically connected to a pair of the power lines."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch-input display devices with force measurement using piezoelectric pillars","description":"A touch-input display device includes a substrate, piezoelectric pillars that are on and extend away from a surface of the substrate, and light emitter devices each coupled to a different one of the p","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9811228","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.
