The diffusion plate (22) opposed to the light-emitting-side surface of the phosphor sheet (21) suppresses a fluctuation of white-color chromaticity due to a view angle, and the diffusion plate (23) opposed to the light-incident-side surface of the phosphor sheet (21) suppresses a fluctuation of white-color chromaticity due to an incident angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Illumination apparatus, display apparatus, and method of producing an illumination apparatus","description":"[Object] To provide an illumination apparatus capable of suppressing a chromaticity fluctuation due to a view angle and an incident angle.[Solving Means] In an illumination apparatus for a display app","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8469530","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.
