A control signal generator in the capacitive sensing circuit is configured to output first and second integral control signals respectively having an opposite phase to and the same phase as the transmitting signal in a first phase mode, and to output the first and second integral control signals respectively having the same phase as and an opposite phase to the transmitting signal in a second phase mode. The first and second integral control signals are mutually opposite to each other. A touch determining part is configured to determine whether a touch is generated based on capacitance values detected in the first and second phase modes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive sensing circuit for multi-touch panel, and multi-touch sensing device having same","description":"A capacitive sensing circuit for a multi-touch panel includes a transmitting circuit configured to supply a transmitting signal to a transmitting line; and a receiving circuit part configured to detec","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9778799","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.
