A cholesteric liquid-crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral. Cholesteric liquid crystals are also known as chiral nematic liquid crystals. They organize in layers with no positional ordering within layers, but a director axis which varies with layers.

2014年2月17日 · Cholesteric liquid crystals (CLCs) are a fascinating genre from the liquid crystalline material family, due, in large part, to the unique optical properties its mesoscopic helical structure imparts...

2018年6月3日 · This review gathers research efforts on diffractive optical elements based on cholesteric liquid crystal (CLC) materials with a supramolecular helical architecture. All main types and fabrication approaches of periodic diffractive structures from CLCs are …

Cholesteric liquid crystals (CLCs) represent the intermediate state between the crystalline phase, which is formed at low temperatures, and the liquid phase, which is formed at a sufficiently high temperature. In this state, rigid molecules are moving similarly to liquid but at the same time they retain a certain degree of arrangement, which is ...

2023年11月16日 · Liquid crystals (LCs) are well known for inherent responsiveness to external stimuli, such as light, thermal, magnetic, and electric fields. Cholesteric LCs are among the most fascinating, since they possess distinctive optical properties …

2024年6月20日 · Cholesteric liquid crystals, with nanostructures similar to those of natural organisms, can be combined with actuators to produce bright structural colors in response to a wide range of stimuli. Structural colors modulated by nano-helical structures can continuously and selectively reflect specific wavelengths of light, breaking the limit of ...

Cholesteric liquid crystals are omnipresent in living matter under both in vivo and in vitro conditions and address the major types of molecules essential to life. In the animal and plant kingdoms, the cholesteric structure is a recurring design, suggesting a convergent evolution to an optimised left-handed helix.

2021年5月5日 · In comparison to the nematic and smectic phase, molecules in cholesteric liquid crystals are incrementally displaced in successive layers to give helical stacking. These cholesteric liquid crystals exhibit in layers with no positional ordering within layers, but the director of the orientation rotates layer by layer in a right or left-handed helix.

1986年11月1日 · It seems certain now that cholesteric liquid crystals (cholesterics, or CLC, for short) have been the first examples of mesomorphic state of matter known to humankind.

Cholesteric liquid crystals are ubiquitous in animal and plant kingdoms. We review the advances and open questions in the cholesteric organisation of DNA, chromatin, chitin, collagen, cellulose, viruses,
