The screen includes a retroreflective layer having a reflection surface directed to the projection device and a diffusion layer arranged on the projection device side with respect to the retroreflective layer and configured to diffuse, when transmitting light made incident from the retroreflective layer, the light wider in a first direction along the center axis than in a second direction, which is a circumferential direction centering on the center axis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display apparatus","description":"A display apparatus includes a screen formed in an arcuate shape centering on a center axis and a projection device configured to project, along projecting directions orthogonal to the center axis and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9791708","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.
