BS IEC 61747‑40‑6 is an international standard that discusses liquid crystal display devices. The main objective of the BS IEC 61747 series is to ensure strength and durability of electronic display devices.
BS IEC 61747‑40‑6 is the 40th part of the BS IEC 61747 series that specifies a mechanical performance testing procedure for cover glass used in electronic flat panel displays in mobile devices.
BS IEC 61747‑40‑6 focuses on the measurement of surface fracture load after flaw introduction via grit particle abrasion. After abrasion, the retained surface fracture load is measured with the method documented in IEC 61747-40-4.
BS IEC 61747‑40‑6 on liquid crystal display devices is relevant to:
Mobile electronic devices have become increasingly sophisticated and often incorporate displays for the purposes of user interface and viewing. Such displays commonly incorporate a transparent cover glass, which aids in protecting the display against the introduction of damage through routine device transport and use, as well as occasional or accidental misuse.
The purpose of BS IEC 61747‑40‑6 is to provide mechanical testing procedures for cover glasses
utilized in such applications. Such glasses can be strengthened, for example via an ion-exchange process, which acts to increase mechanical strength through the introduction of a surface compressive layer.
If you are a manufacturer of display cover glass for mobile devices, BS IEC 61747-40-6 can ensure your products offer the minimum required resistance to abrasion, for optimal performance and durability of the electronic devices. Conformity to the testing procedures can help demonstrate the durability and reliability for your products.
