One side of the unit light guide plate is defined as a light entrance surface and LEDs as the light sources are aligned along the light entrance surface to satisfy p≧a≧c where a indicates the size of the unit diffusion pattern in a direction orthogonal to an exit optical axis of the LEDs, c indicates the size of an LED emission surface in the direction of alignment of the LEDs, and p indicates the pitch of alignment of the light sources."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image display apparatus and backlight apparatus used therefor","description":"A plurality of backlight blocks are aligned, each block includes light sources and a unit light guide plate for guiding light from the light sources to the side of a liquid crystal panel, unit diffusi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514349","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.
