引言

新型显示产业是国民经济和社会发展的战略性、基础性和先导性产业，是决战未来、关系全局、影

响深远、战略必争的高技术领域，加快发展新型显示产业对促进我国产业结构调整、实施创新驱动发展

战略、推动经济发展提质增效具有重要意义。玻璃盖板是新型显示用关键材料之一，为满足我国玻璃

盖板产品的设计、研发、生产及检验的需求，需制定玻璃盖板系列标准。GB/T48020《移动显示器件用

玻璃盖板》规定了移动显示器件用玻璃盖板机械试验方法的要求等内容，拟由六个部分组成。

——第1部分：机械试验方法指南。目的在于规定玻璃盖板关键的机械试验性能参数，主要包

括强度和抗破坏性能。

——第2部分：机械试验方法单轴弯曲强度（4点弯曲）。目的在于规定通过4点弯曲测量玻璃

盖板的单轴弯曲边缘强度。

——第3部分：机械试验方法双轴弯曲失效能量（落球）。目的在于规定通过落球冲击测量玻璃

盖板的双轴弯曲抗冲击性能。

——第4部分：机械试验方法双轴弯曲强度（环对环）。目的在于规定通过环对环产生的双轴弯

曲测量玻璃盖板的表面断裂载荷。

——第5部分：机械试验方法刚性支撑受试件抗尖锐物体的动态撞击。目的在于规定通过落球

冲击测量双轴弯曲抗冲击性能，其失效模式是由尖锐物体接触导致的，是移动显示器件中几

种失效模式之一。

——第6部分：机械试验方法保留双轴弯曲强度（磨损环对环）。目的在于规定通过砂粒研磨的

方式产生裂纹后，测量玻璃盖板的表面断裂载荷。磨损试验后，按照第4部分规定的方法测

量保留表面断裂载荷。
