The drive control unit fixes the frequency of the drive signal to a predetermined frequency when the duty ratio of the drive signal is in a second range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display device for varying the driving frequency of a backlight and driving method thereof","description":"A display device includes a drive control unit that changes a frequency of a drive signal based on a brightness of a light source of a backlight when a duty ratio of the drive signal is in a first ran","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9786231","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.
