Abstract

In the presence of a strong electric field, helices in a cholesteric liquid crystal (CLC) phase might be unwound, leaving liquid crystal (LC) molecules parallel to the electric field, thereby realizing transparency. Previously, we developed a novel particle-doped CLC cell without alignment layers that exhibited liquid crystal display (LCD) capabilities via electro-optical properties. This ability represents a novel advancement in LCD fabrication, resulting in enhanced electro-optical characteristics. To explore the impact of chirality on LCDs, we synthesized and radially constructed cellulose particles. These were then employed as chiral dopants in the production of LCD cells. The fabricated chiral nanoparticle (CNP)-doped PC05 CLC cell showed a high transparency of 97.4% and a fast response time of 7.6 ms. For the prepared radially constructed PDAT-doped PD2T PSCLC cell, a high transmittance of 93.6% and a fast response time of 13 ms were achieved. Fabrication of LCD cells without an alignment layer on substrates was achieved by indicate adding polymeric chiral nanoparticles into CLC mixtures. Adding 2 wt% chiral CNPs promoted the transmittance of the CLCs from 3.4 to 97%. This novel chiral dopant technique enables the use of a new easy method for the fabrication of LCDs. Fabrication of LCD cell without alignment layer on substrates was achieved via simply adding the chiral polymer nanoparticles into CLC mixtures. The fabricated chiral nanoparticle (CNP) doped CLC cell shows a high contrast 97.4% and a fast response time 7.6 ms.

通过纤维素纳米粒子掺杂剂改善胆甾型液晶器件的电光特性
在强电场的作用下,胆甾液晶(CLC)相中的螺旋可能会松开,使液晶(LC)分子与电场平行,从而实现透明。此前,我们开发了一种新型无配位层的颗粒掺杂 CLC 电池,通过电光特性显示出液晶显示(LCD)功能。这种能力代表了液晶制造领域的新进展,从而增强了电光特性。为了探索手性对液晶显示器的影响,我们合成并径向构建了纤维素颗粒。然后将这些颗粒作为手性掺杂剂用于液晶电池的生产。制作的手性纳米粒子(CNP)掺杂 PC05 CLC 电池显示出 97.4% 的高透明度和 7.6 ms 的快速响应时间。在制备的径向构造 PDAT 掺杂 PD2T PSCLC 电池中,实现了 93.6% 的高透光率和 13 ms 的快速响应时间。通过在 CLC 混合物中添加聚合物手性纳米粒子,可以在基底上制作出无配向层的 LCD 电池。添加 2 wt% 的手性 CNPs 使 CLC 的透光率从 3.4% 提高到 97%。这种新颖的手性掺杂剂技术为制造液晶显示器提供了一种新的简便方法。
