A protrusion of the reflective sheet protrudes into a through hole of the light guide plate. The light-emitting unit passes through an opening of the reflective sheet to be accommodated in a slot hole of the light guide plate. The light-emitting unit is configured to emit light to reach a light exit area of the light-shielding sheet through the light guide plate. The electrical connector is aligned with the through hole or further protrudes into the through hole."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backlight module and illuminated keyboard","description":"A backlight module includes a light-shielding sheet, a light guide plate under the light-shielding sheet, a reflective sheet under the light guide plate, a main circuit board under the reflective shee","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11287898","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.
