BS IEC 61747-40-4 is the 40th part of an international standard used for Liquid crystal display devices that specifies the test method for display cover glass. BS IEC 61747-40-4 helps in manufacturing good quality display cover glasses used for mobile devices.
BS IEC 61747-40-4 is a mechanical performance testing procedure for cover glass used in electronic flat panel displays in mobile devices. BS IEC 61747-40-4 focuses on the measurement of as-received surface fracture load via biaxial flexure generated by ring-on-ring.
BS IEC 61747-40-4 on Liquid crystal display devices is useful for:
A liquid-crystal display (LCD) is a flat-panel display that uses the light-modulating properties of liquid crystals combined with polarizers.
BS IEC 61747-40-4 specifies the test apparatus, test methods and procedure for performing tests for mobile devices. This test is useful in measuring the surface fracture load by forcing a ring through a specimen that is supported by another larger ring. With the help of BS IEC 61747-40-4, you can reduce the contact damages and frictions by covering the load rings with polymeric adhesive tape.
By applying BS IEC 61747-40-4, you can ensure the durability and safety of you and your client. This results in manufacturing good quality display cover glass used for mobile devices.
