Upon receiving an OFF signal Soff instructing OFF of the power supply, a balance control circuit controls a drive unit based on a result of the determination of the polarity bias moving direction and on the polarity bias count value Nb at a point of time when the OFF signal Soff is inputted so that the polarity bias can be resolved before a power supply is turned off."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid-crystal display device and method for driving same","description":"Based on a REF/NREF signal coming from a REF/NREF determination circuit, a polarity bias calculation circuit updates a polarity bias count value Nb indicating a degree of a polarity bias of an applied","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9812081","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.
