The lower substrate has opposite side edge portions disposed along a longitudinal axis of the lower substrate, and the side edge portions have an incline or taper along a thickness axis of the lower substrate. A pair of lower electrodes are formed on the resistive film of the lower substrate, and are disposed parallel to the side edge portions of the lower substrate, such that when pressure is applied to an operation portion of the upper sheet, the upper sheet flexes toward the lower substrate, and planar coordinates of the operation portion are determined based on a voltage between the pair of lower electrodes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Input device and display input device using the same","description":"An input device includes an upper sheet having a resistive film formed on a lower surface thereof and a lower substrate disposed in a co-planar relationship below the upper sheet and spaced apart from","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531391","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.
