The device also includes a common voltage supplying part 42 that detects a charge in a certain area T1 of the counter electrode 15 and compares a feedback voltage corresponding to the detected charge in the area, thereby providing common voltage Vcom feedback control. Consequently, flickers on the screen can be prevented by common voltage Vcom feedback control."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for controlling common voltage of the liquid crystal display device","description":"The liquid crystal display device 100 has a matrix arrangement of pixels which are formed by a liquid crystal layer, display electrodes disposed across the liquid crystal layer, and a counter electrod","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537083","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.
