In this configuration, the potential of the first node included in each stage is set to a high level based on a pulse of a scanning signal outputted from a pre-stage, and is set to a low level based on a pulse of a scanning signal outputted from a third stage after a stage concerned."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Shift register, scanning signal line drive circuit provided with same, and display device","description":"An object is shortening a clock fall-rise period while suppressing an increase in a circuit area, an increase in current consumption, and a cost increase, without generating an abnormal operation, in ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531224","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.
