A method for manufacturing the thin film transistor array substrate is also disclosed. The thin film transistor prevents the threshold voltage thereof from being drifted in a case of negative bias illumination stress (NBIS)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thin film transistor array substrate and manufacturing method thereof","description":"A thin film transistor array substrate includes a bottom gate disposed on a substrate and a bottom gate insulating layer covering the bottom gate, a semiconductor oxide layer disposed on the bottom ga","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9778530","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.
