When gate-source voltage of a driving transistor shifts to negative threshold voltage, it is possible to apply the data voltage at positive voltage and to simplify a driving IC, thereby ensuring wide use, by applying voltage of a second power source ELVSS at positive voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Organic light emitting diode display device and driving method thereof","description":"An organic light emitting diode display device includes a display unit including a plurality of pixels; a data driver applying data voltage to the pixels; and a power supplier including a first power ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9761172","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.
