The optical path separation element transmits a part of the image light to the projection lens unit, and reflects a part of the external light emitted from the projection lens unit to the condensing optical system. The condensing optical system condenses the part of the external light reflected by the optical path separation element on the imaging element. A capturing angle of the external light in the condensing optical system is equal to or less than a condensing angle of a lens F-number of the projection lens unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projection display apparatus","description":"A projection display apparatus includes an image light emitter that includes a light modulation element that emits image light, a projection lens unit that projects the image light on a projection tar","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12003897","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.
