偏光片快速测试方法与高温高湿耐候对比分析

Contrastive Analysis of Polarizer Performance between Rapid Test Method and High Temperature and High Humidity Resistance

智能电能表是智能电网构成的重要组成元素。为了用最短时间检验出产品的可靠性,确保产品满足设计要求,纷纷研究最快速有效的方法来寻找产品可能潜在的缺陷,流传一些快速测试方法比较极端。偏光片作为液晶显示智能电表的组成部分,论证偏光片采用其快速测试方法的可行性。通过极端的水蒸煮、泡水等快速测试方法与常规的高温高湿耐候同步对偏光片进行测试,对比结果发现两者并不一致,同时探讨偏光片在快速测试方法与常规高温高湿耐候的失效机理原因,阐明水蒸煮、泡水作为快速测试方法存在的问题。水蒸煮、泡水作为快速测试方法不能代表高温高湿耐候的性能及水平。

Smart meter is an essential element of smart grid composed.In order to test the reliability of the product with the shortest possible time,that ensure the products meet the design requirements.The most rapid and effective way have been studied to find potential product defects possible,and some quick test methods were spread in the industry.The polarizer is one components of liquid crystal display of the smart meter,and accuracy of the rapid test method is evaluated with polarizers.Comparison the extreme water cooking and soaking rapid test methods with the high temperature and high humidity resistance test,the result shows that the two is inconsistent.Two test method failure mechanism was studied,and the problem of water cooking and soaking water rapid test method at polarizer was discussed.The water cooking and soaking used as a rapid test method result that cannot represent the performance and level of high temperature and high humidity resistance.There will be a problem of misjudgment.At the same time,it provides theoretical basic data for seeking rapid test methods.
