The control unit also sequentially switches illumination regions for the pixel regions by the respective color light beams, to allow all of the color light beams to time-divisionally illuminate any pixel region of the pixel regions within the predetermined period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display apparatus that time-divisionally illuminates different pixel regions with diffracted color light beams","description":"An apparatus includes a light source unit that emits color light beams having different wavelengths; a light intensity modulation element including pixels, and subjecting the color light beams to inte","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11953781","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.
