The four electrodes form a light transmission hole being shaped as a parallelogram. The present invention solves the problem that the focal length of the liquid crystal lens cannot be accurately adjusted due to the instability of the impedance of the impedance membrane of the present liquid crystal lens."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical device, imaging device, focus driving method, and method for moving lens center","description":"An optical device includes a first electrode layer, a first alignment layer, a liquid crystal layer, a second alignment layer, and a second electrode layer being arranged in turn along a light transmi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11237451","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.
