The plurality of sensing channels may be configured to supply driving signals to respective first electrodes during a first period, receive sensing signals from respective first electrodes during a second period, and generate the output signals corresponding to the sensing signals received from respective first electrodes based on potentials of the respective reference nodes. A method of driving a touch sensor also is disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch sensor and method of driving the same","description":"A touch sensor includes a sensor unit including a plurality of first electrodes in an active area spaced apart from each other, and at least one second electrode, a plurality of sensing channels respe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11294502","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.
