When a screen of a color corresponding to each field which constitutes one frame period is displayed, LEDs included in the upper-side LEDs (71U) are turned into a light emission state and then LEDs included in the lower-side LEDs (71D) are turned into the light emission state, and the LEDs included in the upper-side LEDs (71U) are turned into a light-off state and then the LEDs included in the lower-side LEDs (71D) are turned into the light-off state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display device","description":"In a liquid crystal display device capable of performing image display while keeping a background in a transparent state, field-sequential driving is performed without causing color mixing.A backlight","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9697777","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.
