The automatic detection method for defects of the display panel can accurately acquire the location of the defect and the difference between the defective area and the normal area to quantify and discriminate the defects of the display panel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automatic detection method for defects of a display panel","description":"An automatic detection method for defects of a display panel is disclosed, which comprises: acquiring a tag image, a mapped original image and a mapped tag image; dividing the mapped original image in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9646370","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.
