The driver backplane includes a base, a trace layer, and an insulating protection layer stacked successively in a direction away from the light-emitting unit array. The trace layer includes a plurality of traces and one or more bonding terminals each electrically connected to one of the traces. An orthographic projection of the insulating protection layer on the base overlaps the traces. The insulating protection layer includes one or more first opening each exposing one of the bonding terminals. The insulating protection layer is disposed on an outermost side of the side of the driver backplane away from the light-emitting unit array."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light boards, methods of manufacturing a light board, and spliced display devices","description":"A light board includes a light-emitting unit array including a plurality of light-emitting units arranged in an array and a driver backplane disposed on a backlight side of the light-emitting unit arr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11988921","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.
