摘要： A polymer-dispersed blue-phase (PDBP) liquid crystal film is formed from a polymer-based latex and blue-phase liquid crystals that are combined using an emulsification process or a polymerization-induced phase separation process. The resultant PDBP liquid crystal film includes droplets formed by the polymer-based latex that encapsulate the blue-phase liquid crystals therein, so as to allow the blue-phase liquid crystals to have a blue phase at room temperature. As such, the PDBP liquid crystal film is conducive for use in manufacturing processes, such as LCD (liquid crystal display) manufacturing processes, while providing desirable optical features, such as field-induced birefringence at low switching voltages.

摘要翻译：聚合物分散蓝相（PDBP）液晶膜由使用乳化法或聚合引发的相分离方法结合的聚合物基胶乳和蓝相液晶形成。所得到的PDBP液晶膜包括由其中包封蓝相液晶的基于聚合物的胶乳形成的液滴，以使蓝相液晶在室温下具有蓝相。因此，PDBP液晶膜有利于在诸如LCD（液晶显示）制造工艺的制造工艺中使用，同时提供所需的光学特征，例如在低开关电压下的场致双折射。

摘要： A surface-stabilized in-plane switching (SS-IPS) liquid crystal (LCD) cell includes a pair of spaced substrates that include alignment layers disposed thereon. The alignment layers are treated to define a first director orientation. Disposed between the alignment layers is a liquid crystal material that contains polymer fibrils that are disposed upon each of the alignment layers. The polymer fibrils serve to maintain the alignment of the liquid crystal molecules in the first director orientation when no voltage is applied to the LCD cell via interdigitated electrodes disposed upon the alignment layers, thus improving the dynamic response of the SS-IPS LCD cell.

摘要： A surface polymer-assisted vertically aligned (SPA-VA) liquid crystal (LC) cell has a surface alignment layer of surface localized polymer nano spikes capable of controlling the pretilt angle of liquid crystal molecules and ensuring fast switching characteristics. The deposition of the polymer nanospikes as a part of the alignment layer is achieved by polymerizing a small amount of a reactive monomer in vertically aligned liquid crystal with or without an applied voltage. Due to the alignment of liquid crystal molecules by the surface alignment layers, the polymerized polymer acts as an internal surface to modify and control the field-induced reorientation of the liquid crystal molecules. The SPA-VA LC cell realizes a stable alignment and the considerable advantage of the formation of polymer spikes via UV irradiation on both substrates of the cell. Furthermore, the switch-off of a SPA-VA is fast due to the enhanced surface anchoring strength by the surface-localized polymer nano spikes.
摘要翻译：表面聚合物辅助垂直取向（SPA-VA）液晶（LC）单元具有能够控制液晶分子的预倾角并确保快速切换特性的表面局部聚合物纳米尖峰的表面取向层。作为取向层的一部分，聚合物纳米球的沉积是通过在施加或不施加电压的情况下将垂直取向的液晶中的少量反应性单体聚合而实现的。由于通过表面取向层对液晶分子进行取向，所以聚合的聚合物充当内部表面，以改变和控制液晶分子的场诱导重定向。 SPA-VA LC细胞实现了稳定的对准，并且通过UV照射在细胞的两个底物上形成聚合物尖峰的相当大的优点。此外，SPA-VA的关闭是快速的，这是由于表面定位的聚合物纳米尖峰增强的表面锚固强度。
