The triangular wedge includes a first incident surface, a first emergent surface, and a second emergent surface. The included angle formed between the first emergent surface and the second emergent surface is 5°. The first incident surface is opposite to the light source. The reflecting device is disposed at one side of the first emergent surface to reflect the light rays from the first emergent surface back to the triangular wedge. The deflection-collimating device is disposed between the second emergent surface and the liquid crystal display to refract parallel beams from the second emergent surface to generate light rays vertical to the plane of the liquid crystal display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backlight module for liquid crystal display","description":"A backlight module for a liquid crystal display including a light source, a triangular wedge for generating parallel beams, a reflecting device, and a deflection-collimating device, all of which are d","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9715141","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.
