聚合性化合物、组合物、液晶显示器件 技术领域
本发明涉及液晶显示材料领域,具体涉及新型聚合性化合物、组合物、以及液晶显示器件。
背景技术
目前,液晶化合物的应用范围拓展的越来越广,其可应用于多种类型的显示器、电光器件、传感器等中。用于上述显示领域的液晶化合物的种类繁多,其中向列相液晶应用最为广泛。向列相液晶已经应用在无源TN、STN矩阵显示器和具有TFT有源矩阵的系统中。
对于薄膜晶体管技术(TFT-LCD)应用领域,宽视角模式、高透过率、高分辨率已成为行业内追求的目标,目前主流的宽视角技术主要采用VA垂直取向、IPS面内开关及FFS边缘场开关等显示类型。这些显示模式,广泛采用具有负介电各向异性的液晶介质或正介电各向异性的液晶介质。
对于PS-VA(Polymer Stabilized Vertical Alignment,聚合物稳定垂直取向)、PS-FFS(Polymer Stabilized Fringe Field Switching,聚合物稳定边缘场开关)、PS-IPS(Polymer Stabilized In-Plane Switching,聚合物稳定平面转换)等液晶显示模式的液晶显示器件,在基板间配置含有聚合性化合物的液晶组合物的状态下,根据情况在基板间施加电压使液晶分子取向,并在取向的状态下照射紫外线等,由此使得聚合性化合物聚合固化从而使得液晶分子的取向状态被记忆到固化物。
对于这样的液晶显示器件,还存在品质稳定性、制作工艺导致的生产效率不高等问题。因此,如何提高聚合性单体化合物的聚合反应速率从而提高生产效率、以及品质稳定性的提高是本领域亟待解决的问题之一。

聚合性单体化合物在一定时间的反应聚合转化率可以评价聚合性单体的聚合反应速率。反应聚合转化率越大,表明聚合性单体的聚合反应速率越快。

实施例6 39.8% 56.1% 66.5%
从表4可知,实施例1~6的聚合性单体化合物经紫外线照射能量3J、6J、9J后,其聚合反应转化率均高于对比例1,由此说明实施例1~6的聚合性单体化合物的聚合反应速率皆快于对比例1的化合物。因此从表4结果可以认为,实施例1~6的聚合性液晶单体化合物具有快速聚合性能,可以缩短现有量产聚合物稳定排列制程时间。
进一步,将实施例、比较例的反应型液晶组合物注入测试盒(TN模式,盒厚=4.0μm,PI,SE-7951)中后,同时控制照射紫外线射总能量在9J的固定照 射条件下,照射对比例、实施例的反应型液晶组合物,并在固定温度60℃、电压5V、频率60Hz的条件下,测试设备为TOYO VHR-AMP01来测量紫外线照射前后的电压保持率(VHR)。结果示于后述的表5。
表5:实施例及对比例的聚合性组合物的电压保持率
Figure PCTCN2023071139-appb-000077
通过表5中的VHR(电压保持率)结果显示,母体液晶添加聚合性单体化合物后经紫外线(UV)照射后的VHR会明显高于未添加聚合性单体化合物的母体液晶,而其中实施例1~6的聚合性液晶单体组合物经紫外线照射后的电压保持率(VHR)表现也明显优于对比例1,说明实施例1~6的聚合性液晶单体具有高电压保持率的性能。
本发明可用其他的不违背本发明的精神或主要特征的具体形式来概述。因此,无论从哪一点来看,本发明的上述实施方案都只能认为是对本发明的说明而不能限制本发明,权利要求书指出了本发明的范围,而上述的说明并未指出本发明的范围,因此,在与本发明的权利要求书相当的含义和范围内的任何改变,都应认为是包括在本发明的权利要求书的范围内。
