The receiving/transmitting element is not arranged on both the x-axis and the y-axis so that an infrared ray scans a touch area in a matrix configuration, but an infrared receiving/transmitting element is arranged on only one of the x-axis and y-axis so that one receiving module sequentially scans the touch area using a right-angle scan measurement signal and an oblique-angle scan measurement signal. The multi-touch screen device may decrease the number of receiving/transmitting elements for use and solve a ghost image problem that occurs in a multi-touch operation that uses infrared rays."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-touch screen device","description":"Provided is a multi-touch screen device that may calculate x and y orthogonal coordinates of a touch area even if a receiving/transmitting element is arranged on only one of the x-axis and the y-axis.","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9671882","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.
