Study of measurement technique on military LCD under strong light

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%.
