A threshold voltage and/or a carrier mobility of the drive transistor is compensated by application of the reference current during the combined programming and compensation phase."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"TFT compensation circuit for display device using reference current","description":"A pixel circuit for a display device includes a drive transistor configured to control an amount of current to a light-emitting device during an emission phase depending upon a voltage applied to a ga","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10497310","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.
