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
液晶显示器件
BS IEC 61747-40-5:2018 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 associated with
damage introduction via sharp contact. Crack propagation is enhanced by central tension in
the case of strengthened glass. This failure mode represents one of several field failure
modes observed in mobile devices.Cross References:JIS R6111ISO 8512-2ISO 6344-1IEC 61747-40-1All current amendments available at time of purchase are included with the purchase of this document.
