The detection light-source section is movable relative to the housing, and outputs the invisible light in a direction parallel to or a direction forming a fixed angle with respect to the projection plane."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projection display unit","description":"A projection display unit includes, in a housing, a visible light illuminator, a light valve that modulates a first polarized component included in light outputted from the visible light illuminator, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10521054","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.
