Therefore, optical efficiency can be improved while simplifying a structure and a component of the projector so that manufacturing costs and an installation space can be reduced and display quality can be improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fly-eye lens and optical engine for projector including same","description":"An optical engine for a projector according to an embodiment of the present invention comprises: a first light source unit; a second light source unit which outputs a light with a color which is diffe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9851630","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.
