The drive-sense module includes a difference detection circuit to generate a signal representative of light detected by the LED in the first mode and a signal representative of light emitted by the LED in the second mode and a bi-directional dependent current source configured to output an error correction current to the first input of the difference detection circuit based on the output of the difference detection circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Drive sense circuit for an LED touch panel","description":"A drive-sense module for a light emitting diode (LED) touch-sense panel includes an input source for providing a forward bias reference signal and a reverse bias reference signal, a first conversion c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11269458","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.
