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.

Feb 17, 2014 · 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.

Cholesteric liquid crystals (CLCs) possess a helical structure and exhibit two stable states at a zero field: in the focal conic texture, they scatter light in forward directions, whereas in the planar texture, they reflect circularly polarized light with the same handedness as the helical axis.

Cholesteric liquid crystal (ChLC) materials with broadband reflection are witnessing a significant surge in interest due to their unique ability to self-organize into a helical supra-molecular architecture and their excellent selective reflection of light based on the Bragg relationship.

This paper reviews published work on the responses of cholesteric liquid crystals to various stimuli, applications that have been developed, methods of use, liquid crystal materials themselves and their properties.

The roles and functions of biological cholesteric liquid crystals include maximisation of packing efficiency, morphogenesis, mechanical stability, optical information, radiation protection and evolution pressure.

Nov 16, 2023 · 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 …

Oct 30, 2024 · Cholesteric liquid crystals (ChLCD) are materials with bistable properties. Their excellent reflective properties make them a key display technology. They are widely used in electronic displays, including monochrome, multi-color, and even full-color paper-like displays.

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, silk fibroin and cholesterol esters.

Liquid Crystal Thermometers As demonstrated earlier, chiral nematic ( cholesteric) liquid crystals reflect light with a wavelength equal to the pitch. Because the pitch is dependent upon temperature, the color reflected also is dependent upon temperature.
