The present application also provides related apparatus and computer readable storage medium."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image quality optimization method based on local dimming, apparatus, and computer readable storage medium","description":"An image quality optimization method based on local dimming includes: based on an input image signal, calculating a PWM duty cycle of a current image signal corresponding to each of backlight regions;","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11289052","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.
