Study of measurement technique on military LCD under strong light

摘要: 为满足军用液晶显示屏质量与可靠性的客观准确测试评价需求，研制了一种照度达到10⁵ lx量级、适用于强光环境下的军用液晶显示屏检测装置，阐述了强光光源、响应时间检测模块、大型三轴检测平台等关键部件的设计，对响应时间、亮度均匀性、高温显示正常性等核心参数的检测方法进行了研究，最后对一种加固型液晶显示屏进行检测，响应时间的测量精度优于3%。

Abstract: In order to meet the requirements of evaluating the quality and reliability objectively and accurately for military LCD, a kind of detection device for military LCD under strong light which illuminance can up to 10⁵ lx was developed. First, the design of the key components such as strong light source、response time detection module and big triaxial detecting platform were described. The critical detection methods about response time、brightness uniformity and display normally at high temperature were then studied. Finally, a rugged LCD was detected, the test result of experiment proves that the measurement accuracy of response time is better than 3%.
