The illumination light from a light source is converted into s-polarized light by a polarization converting system, and energy distribution thereof is made uniform by a rod integrator. Then, the illumination light is sequentially split into three color lights, R, G, and B, by a color wheel. The illumination light is approximately totally reflected on the PBS sheet, and applied toward a liquid crystal display panel. The illumination light having been reflected on the PBS sheet illuminates the panel surface with neither too large nor too small illumination range. The R, G, and B component images having been reflected on the panel surface are sequentially projected on a screen so as to be observed as a full color image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reflective liquid crystal projector","description":"A PBS sheet is curved into a partially cylindrical shape so as to be concave or convex toward a panel surface along a central axis which is perpendicular to both an incident light axis of illumination","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508677","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.
