A capacitive touch detection device includes: a sensor pattern (10) forming a touch capacitance (Ct) in between a touch input device and the sensor pattern; an auxiliary capacitor (Caux) connected on one side to the sensor pattern (10) and having a driving voltage for touch detection applied to the other side thereof; a charging unit (12) for providing pre-charge signals to the touch capacitance (Ct) and the auxiliary capacitor (Caux); and a touch detection sensor (14) which is connected to the sensor pattern (10) and which detects a touch signal by detecting a voltage difference in the sensor pattern (10) when the touch capacitance (Ct) is added to the auxiliary capacitor (Caux) according to a touch of a touch input instrument. Effects of parasitic capacitance generated due to noise, coupling phenomena and other factors are minimized, to thus stably acquire touch signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voltage difference-based capacitive touch detection device, capacitive touch detection method and capacitive touch screen panel, and display device with built-in capacitive touch screen panel","description":"Provided is a new capacitive touch detection device, detection method, and touch screen panel for detecting a touch signal by detecting a voltage difference of a sensor pattern from a driving voltage ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9740359","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.
