A wavelength of the third color light is shorter than that of the fourth. The first filter attenuates light at a wavelength exceeding a first threshold set in a dimming wavelength region between a wavelength region of the third and fourth color lights. The second filter attenuates light at a wavelength equal to or less than a second threshold set in the dimming wavelength region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projector","description":"A projector includes: an illumination device; first color separation device that separates first and second color light from light emitted from the illumination device; second color separation device ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10508779","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.
