Liquid crystal display devices - Mechanical testing of display cover glass for mobile devices. Strength against dynamic impact by a sharp object with the specimen rigidly supported Ingestion-build-44616 and information on permanent magnet1 Scope This part of IEC 61747 is a mechanical performance testing procedure for cover glass used in electronic displays in mobile devices. This document focuses on the measurement of surface impact energy required to fracture a specimen due to the collision of sharp particles onto the surface of a cover glass. This is achieved by dropping a ball on a sheet of coated abrasives placed on the cover glass, which is rigidly supported. The failure mode is
