The plurality of pigments includes a first and a second type of organic pigment particle. The first type of organic pigment particle has a first color and a first charge polarity. The second type of organic pigment particle has a second color different from the first color and a second charge polarity the same as the first charge polarity. At least one of the first and second types of organic pigment particle includes a silica coating and a polymeric stabilizer covalently bonded to the silica coating."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Color organic pigments and electrophoretic display media containing the same","description":"An electrophoretic display medium includes a front and a rear electrode, at least one of the front and rear electrodes being transparent, and an encapsulated dispersion fluid containing a plurality of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11493820","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.
