By setting two common electrode voltages, TFT-LCD and its driving method provided by the invention can make dynamic range of input voltage required for driving liquid crystal display device be smaller than dynamic range of driving voltage of liquid crystal driving voltage-transmittance curve, thus reducing power consumption during driving the liquid crystal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thin film transistor-liquid crystal display device and its driving method","description":"The invention discloses a TFT-LCD and its driving method, TFT-LCD comprises an array substrate and a color filter substrate, a common electrode on said color filter substrate being divided into multip","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9740057","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.
