The encapsulation includes an encapsulation resin and a plurality of refractive particles distributed in the encapsulation resin. The encapsulation layer encapsulates the white light emitting unit, the red flip-chip LED, the green flip-chip LED, and the blue flip-chip LED. Moreover, electrodes of the white light emitting unit, electrodes of the red flip-chip LED, electrodes of the green flip-chip LED, and electrodes of the blue flip-chip LED are exposed from the encapsulation layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Chip-scale LED package structure","description":"A chip-scale LED package structure includes a white light emitting unit for emitting a white light, a red flip-chip LED for emitting a red light, a green flip-chip LED for emitting a green light, a bl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11257795","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.
