The optical film laminate formed as a continuous web with the predefined slit lines for use in a continuous manufacturing system by laminating optically functional film sheets to liquid-crystal panels. The optical film laminate having defect-free regions having a predefined length corresponding to the dimension of a liquid-crystal panel and defective regions having a predefined length different from the defect-free region, based on the detected position of defects. The optical film laminate having a carrier film releasably laminated to an adhesive layer, wherein defect-free normal polarizing sheets and a defective polarizing sheets are formed on the carrier film by forming slit lines corresponding to above regions along the transverse direction of the optical film laminate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Continuous web of optical film laminate with predefined slit lines, and method and system for manufacturing the same","description":"An optical film laminate that has predefined slit lines for enhancing both product accuracy and manufacturing speed in liquid-crystal display element manufacturing to radically improve manufacturing y","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8491737","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.
