显示器和反铁电液晶

Displays and antiferroelectric liquid crystals

Ondrej Hudak, Matej Hudak, Jana Tothova

摘要:

最近,我们建立了双层二聚手性反铁电液晶理论。由于棒状液晶分子的芳香核与碳纳米管壁的蜂窝状结构之间的强相互作用,增强了自发极化。纳米管的分散促进了各相中的所有弛豫模式,从而提高了弛豫频率。该复合系统具有改善的电光性能,可用于现代显示应用。SmC* LC由作者之一(OH)研究,即它们从SmC相的转变。向错在外加电场中的作用由O. SmC* 结构中的Hudak。虽然在上述论文中研究了SmC*(FLC)中的波动和向错的作用,但是在SmC*A中的波动和向错的作用以及在SmC*A相中添加MWCNT的作用还没有很好地理解。因此,我们的理论描述(AFLC),包括SmC*A介绍,可用于研究这些影响。

英文摘要:

Recently we have formulated theory of bi-layer-dimerized chiral liquid antiferroelectric crystals. The spontaneous polarization has been increased owing to the strong interaction of the aromatic cores of the rod like liquid crystal molecules with the honey-comb pattern of the CNT walls The SmC*A ordering is improved around the CNTs. All relaxation modes in each phase are facilitated by dispersion of nanotubes whicg enhances the relaxation frequencies. This composite system with improvement in electro-optical properties can be exploited in modern display applications. SmC* LC were studied by one of t he authors (OH), namely their transition from the SmC phase. The role of disclinations in an applied electric field was studied by O. Hudak in the SmC* structure. While the role of fluctuations and of disclinations in the SmC* (FLC)was studied in the above papers, the role of fluctuations and disclinations in SmC*A and the role of addition of MWCNTs in SmC*A phaseis not well understood. Our theoretical description of (AFLC) including SmC*A introduced in may thus be used to study these effects.
