Each of the detection circuits includes a switched capacitor circuit that continues sampling of a signal from each of the X sensor electrodes, to which the detection circuits are connected, not only at a timing that is in synchronization with the plurality of pulses that are applied to the Y sensor electrodes, but also at a timing at which the pulses are not applied to the Y sensor electrodes. For example, the switched capacitor circuit is an integration circuit, or an integration circuit with a finite impulse response (FIR) filter or an infinite impulse response (IIR) filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch panel control circuit and semiconductor integrated circuit using the same","description":"A touch panel control circuit includes a plurality of drive circuits which are connected to Y sensor electrodes, respectively, and which apply a plurality of pulses to a corresponding Y sensor electro","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9811219","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.
