The glass substrate is positioned at a fixture and the front perimeter edge portion of the glass substrate is ground by moving a grinding wheel around the periphery of the glass substrate to establish a rounded surface about and around the periphery of the glass substrate and between the planar front surface and a rear portion of the perimeter edge of the glass substrate. The rounded surface has a radius of curvature of at least 2.5 mm. The rounded surface provides a curved transition between the planar front surface of the glass substrate and the rear portion of the perimeter edge of the glass substrate. The planar rear surface of the glass substrate is coated with a coating."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of making a mirror substrate for a vehicular rearview mirror assembly","description":"A method of making a mirror substrate for a vehicular rearview mirror assembly includes providing a glass substrate having a planar front surface, a planar rear surface and a circumferential perimeter","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11472340","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.
