摘要

为了研究碘代物杂质对TFT液晶性能的影响，设计了不同劣化条件下TFT液晶的保存实验，进行了碘代物掺杂的浓度梯度实验，测试了混晶VHR随碘代物浓度变化的趋势。实验结果表明：在UV照射和加电的劣化条件下，液晶中的碘代物杂质会发生分解，明显降低TFT液晶的VHR参数。液晶中碘代物杂质含量越高，TFT液晶在劣化条件下的稳定性就越差。在本实验条件下，210

Abstract

In order to realize the influence of iodide impurity on TFT liquid crystal mixture

the experiments of adding iodide impurity in the TFT liuquid crystal mixture was designed.Based on the effects of UV light and low current

the relationship between the VHR test value of TFT liquid crystal mixture and the iodide concentration was analyzed. Experimental results indicate that

in the condition of UV light and low current

the VHR value of TFT liquid crystal mixture will be significantly decreased because of the decomposition of trace iodide impurity.If the iodide concentration in the liquid crystal mixture is higher

the reliability of the liquid crystal mixture will be more worse.Under the condition of this experiment

the reliability of liquid crystal mixture has obvious variation when the iodide concentration is over 2010
