A light redirecting optical element is optically coupled to the second side of the first cladding layer, and includes a plurality of light redirecting features directing frustrated totally internally reflected light from the plurality of light extraction features toward the reflective spatial light modulator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reflective display comprising a frontlight with extraction features and a light redirecting optical element","description":"A display includes a reflective spatial light modulator having a reflective surface, a lightguide comprising a core layer, a first cladding layer, and a light emitting region comprising a plurality of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9651729","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.
