为了对液晶滴注工艺和相关不良进行优化改善,本文研究了真空对合之后液晶屏内液晶扩散时间与位移的关系.在牛顿流体假设前提下提出了液晶屏倾斜放置下液晶扩散的模型.数学推导证明,前人研究的平放状态下的方程是倾斜角度为0°时的特殊情况.通过两种状态模型计算数据对比可以得出:位移越大,重力对倾斜状态扩散时间影响越显著,这是在同等扩散位移下两种状态扩散时间的差异所在.面板尺寸大小、形状分布设计等参数会影响液晶扩散的最终形状;液晶盒内间隙、隔垫物会影响液晶扩散速度,间隙越均一,隔垫物密度越小,扩散受到的影响越小.实验研究表明,实测的数据与模型理论计算数据基本相符,基于牛顿流体假设下的模型可以较好地预测液晶的扩散行为.
