The light sensing part generates a control signal corresponding to a variation in the amount of external light when the liquid crystal display panel is touched. The capacitance sensing part varies the control signal based on a variation in the capacitance of the liquid crystal capacitor when the liquid crystal display panel is touched. The sensing signal output part generates a sensing signal in response to the control signal and determines an output timing of the sensing signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch sensor, liquid crystal display panel having the same and driving method for the same","description":"A touch sensor is installed inside a liquid crystal display panel to sense a touch operation and includes a light sensing part including a photodiode, a capacitance sensing part including a liquid cry","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537124","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.
