The method for synchronizing input and output synchronization signals, includes generating an output synchronization signal whose output period is set based on a comparison result between an input period of an input synchronization signal and a previous output period of the output synchronization signal, and limiting the output period of the output synchronization signal within a predefined limit range from the previous output period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and circuit for synchronizing input and output synchronization signals, backlight driver of liquid crystal display device using the same and method for driving the backlight driver","description":"Disclosed are method and circuit for synchronizing input and output synchronization signals, which can synchronize an output synchronization signal based on frequency change of an input synchronizatio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9672775","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.
