• 31.120 Electronic display devices

This part of IEC 61747 provides mechanical performance testing guidelines for cover glass used in electronic flat panel displays in mobile devices. This document focuses on key mechanical testing performance parameters and covers mainly strength and damage resistance attributes. The test methods focus on the cover glass level testing only.

NOTE The glass used for cover glasses for electronic mobile devices can be chemically strengthened by an ion-exchange process. This ion exchange process increases the mechanical strength of the glass.
