【摘要】：通过对大量残影不良样品进行分析,找到了残影不良产生的原因,并基于分析结果设计了改善残影的实验。通过分析发现:残影不良产生的原因是彩膜侧像素与黑矩阵之间的段差过大,在摩擦工程时段差过大区域形成了摩擦弱区,摩擦弱区内的液晶分子配向较弱,导致不良产生。为降低残影不良进行实验,结果显示:在彩膜侧加覆盖层可以有效降低残影不良的发生率,但不适用于量产;通过采用高预倾角的配向膜材料,同时控制配向膜工程到摩擦工程的时间,可使残影不良发生率由28.2%降低至0.2%,为企业的稳定高效生产奠定了基础。
[Abstract]:Through the analysis of a large number of residual bad samples, we found the causes of the residual bad image. Based on the analysis results, we designed the experiment to improve the residual image. Through the analysis, we found that the reason for the bad image is that the segment difference between the color film side pixels and the black matrix is too large. The weak region of friction is formed in the region of excessive difference in friction engineering period, and the molecular alignment of liquid crystal in the weak region of friction is weak, which leads to bad result. Experiments are carried out to reduce the residual bad. The results showed that the incidence of residual bad images could be effectively reduced by adding a coating on the side of the color film, but it was not suitable for mass production. By adopting the high predip orientation membrane material and controlling the time from the matching membrane engineering to the friction engineering, the incidence of residual bad image can be reduced from 28.2% to 0.2%. For the stable and efficient production of enterprises laid the foundation.
