At the bottom portion (1a) of the case (1), four recessed portions (10) are formed in a horizontal direction of a display screen, and each of the LED modules 2 is fixed thereon with screws (11). At opposite ends of the recessed portion (10), opening portions (10a) and (10b) each having a lid member (13) are formed, thus making it possible to remove the LED modules (2) without disassembling the backlight device (100)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backlight device and liquid crystal display apparatus using same","description":"A backlight device (100) includes: a case (1); a plurality of LED modules (2) provided in series on a bottom portion (1a) of the case (1); a reflective sheet (3); a diffusing plate (4); and an optical","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531621","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.
