The optical pattern is composed of a diffusion pattern implemented as at least one layer, or a combination of the diffusion pattern layer and a light shielding pattern. The light unit forms an optical pattern for shielding or diffusing light on a surface of a light diffusion plate of the back-light unit, and combines a diffusion pattern and a metal pattern to attain uniformity of light and realize a yellow-light shielding effect, thus leading to a reliable light quality."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light unit and a LCD liquid crystal display comprising the light unit","description":"Provided is a light unit including a plurality of LED light sources formed on a PCB, a resin layer stacked on the PCB to diffuse and guide emitted light forwards, and a diffusion plate having an optic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9678382","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.
