The light-emitting device includes a pixel; a first circuit configured to generate a signal including information about a value of current extracted from the pixel; and a second circuit configured to correct an image signal in accordance with the signal. The pixel includes a light-emitting element; a transistor whose drain current has a value determined in accordance with the image signal; a first switch configured to control supply of the drain current to the light-emitting element; and a second switch configured to control extraction of the drain current from the pixel and control the supply of the drain current to the light-emitting element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light-emitting device capable of correcting variation in luminance among pixels","description":"A light-emitting device is provided, which is capable of correcting variation in luminance among pixels due to variation in electrical characteristics, such as threshold voltage or mobility, among dri","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9659526","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.
