GB/T 18910.5-2008 is the fifth part of the standard for liquid crystal and solid state display devices, focusing on environment, durability and mechanical test methods. The standard specifies the conditions, procedures and evaluation criteria for environmental tests such as temperature Humidity and salt fog, as well as mechanical tests such as fatigue and vibration. By simulating various use scenarios, the performance Stability and Reliability of display devices under different environments and mechanical stresses are tested, and technical specifications are provided to ensure product mass.
