目前, TFT-LCD行业已经趋于成熟。各大面板厂都在提升自身产品的竞争力：高分辨率、高色域、轻质化、窄边框化以及高对比度等等。配向膜作为LCD面板的主要构成起着重要的取向作用, 其印刷的质量对产品良率起很大影响。喷墨打印作为大世代线配向膜印刷方法被越来越广泛的应用, 但是其带来的印刷性不良也多种多样。本文重点介绍了阵列基板的设计对配向膜的影响。通过实验验证得出, 阵列基板深孔设计对配向膜扩散起到了阻碍扩散的不良影响。从此结论出发, 从配向膜印刷工艺和设计提出改善方案并取得了改善效果。

At present, the TFT-LCD industry is maturing. The panel enterprises continue to improve competitiveness of their products; high resolution, high color gamut, narrow bezel and high contrast ratio and so on. This paper expounds how the design of array substrate matches the alignment film diffusion. It is said that the via hole in the array substrate could block the alignment film diffusion uniform. With the upgrade of the coating method of alignment film and array substrate design, it has been improved.
