The optical filter aligns the optical paths of display light of the greater distance optical system and the closer distance optical system and guides the display light to the image reflection surface. Further, the powers of the greater distance optical system and the closer distance optical system are set to be different."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Head up display apparatus","description":"An optical filter having spectral properties that reflects light of a first wavelength band and transmits light of a second wavelength band that does not include the first wavelength band is provided ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10481394","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.
