From the change trend, adverse influences of the image sticking on the display performance may be reflected accurately and fully such that related comprehensive modifications may be made by the skilled based on defects caused by the image sticking in the display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device of estimating image sticking grade of display","description":"It is provided a method of estimating an image sticking grade of a display, comprising steps of: displaying a first image in a first frame and a second image in a second frame on the display; switchin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9715843","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.
