A driving TFT, a switching TFT, and an organic EL element are provided between a power supply wiring line and a common cathode, and a capacitor and a switching TFT are provided between a gate terminal of the driving TFT and a data line. A switching TFT is provided between a connection point B between the capacitor and the switching TFT and a reference supply wiring line, a switching TFT is provided between the gate terminal and a drain terminal of the driving TFT, and a switching TFT is provided between the gate terminal of the driving TFT and the connection point B."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current-driven display device","description":"In one embodiment of the present invention, to allow a circuit that compensates for variations in a threshold voltage of a drive element to operate properly and prevent luminances of other pixel circu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8514161","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.
