讨论了高分辨率液晶显示屏单滴填充（ODF）工艺中的液晶滴斑问题.本文从液晶材料、滤色器结构和ODF工艺等方面探讨了液晶液滴不均匀的成因。实验结果表明，较低的LC自由能、较高的CF光间隔层密度（PSD）和光间隔层高度（PSH）可以有效地降低LC液滴不均匀的比例和程度。在生产高分辨率移动的TFT-LCD时，应优先使用具有低自由能的LC和具有高PSD和PSH的CF，以提高成品率。
Liquid crystal (LC) drop mura in one drop fill (ODF) process for high resolution panel is discussed. In this paper, we investigated the origin of LC drop mura from aspects of LC materiasl, color filter (CF) structures and ODF process. According to our experiments, it indicated that lower free energy of LC, higher photo spacer density (PSD) and photo spacer height (PSH)of CF could reduce the ratio and degree of LC drop mura effectively. When producing high resolution mobile TFT-LCDs LC with low free energy and CF with high PSD&PSH should be prior used to improve the yield.
