移动设备已经成为人们日常生活中不可或缺的一部分,而液晶显示器则是移动设备的核心部件之一。为了保证移动设备液晶显示器的质量和可靠性,IEC 61747-40-5:2018标准规定了液晶显示器覆盖玻璃的机械测试方法,主要测试其对锐利物体动态冲击的强度。

该标准要求使用一种锐利物体(如针头、刀片等)在一定速度下对液晶显示器覆盖玻璃进行冲击,测试其是否能够承受冲击并不破裂或产生裂纹。测试时,液晶显示器覆盖玻璃必须被刚性支撑,以模拟实际使用中的情况。

IEC 61747-40-5:2018标准规定了测试设备的要求,包括冲击器、支撑装置、测试样品夹具等。测试时,需要对测试样品进行多次冲击,以确定其强度。测试结果应该包括样品的破裂或裂纹情况、冲击力和冲击速度等参数。

该标准还规定了测试条件,包括温度、湿度、气压等环境因素,以确保测试结果的准确性和可重复性。测试结果应该根据标准要求进行评估,以确定样品是否符合要求。

IEC 61747-40-5:2018标准的实施可以有效保证移动设备液晶显示器覆盖玻璃的质量和可靠性,提高移动设备的使用寿命和安全性。
