The clock signal (CK(M)) is merely in charge of the output of the GOA unit of corresponding stage, which can effectively reduce the loading of the clock signal. It ensures that the entire loading of the clock signal after the GOA units of multiple stages are coupled to promote the output stability of the GOA circuit, and to realize the forward-backward scan of the GOA circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"GOA circuit based on LTPS semiconductor thin film transistor","description":"The present invention provides a GOA circuit based on LTPS semiconductor thin film transistor to control the voltage levels of the first node, the second node and the third node (Q(n), P1(n), P2(n)) w","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9841620","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.
