The sensing circuit eliminates the parasitic capacitance effect on the signal lines and rapidly accumulates charges for an amplifier in sensing to thereby increase the operational speed of the sensing circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch panel sensing circuit","description":"A touch panel sensing circuit senses a voltage variation of a coupling capacitor formed between a first directional signal line and a second directional signal line separated from the first directiona","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514191","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.
