When a display driving signal is applied to an i-th group of gate driving lines for performing a display driving, the liquid crystal capacitor corresponding to the i-th group is set to a predetermined voltage, where i=1 to N. Finally, a touch driving signal is applied to an i-th common voltage conductive line corresponding to the i-th group for sensing touch points, so as to reduce touch sensing affections caused by noises of the liquid crystal display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-touch system and method for controlling liquid crystal capacitors to reduce touch sensing interference","description":"A multi-touch system for controlling liquid crystal capacitors to reduce touch sensing interferences includes K gate driving lines, which are divided into N groups each corresponding to a common volta","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9639192","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.
