Progress of Chiral Dopants for Displaying Liquid Crystals

Chiral dopants play an important role in liquid crystal displays,which can convert nematic phase to cholesteric phase.This article briefly introduced the development of chiral dopants and analyzed the requirement of chiral dopants for various modes.The emphasis placed on chiral dopants used in TFT and cholesteric liquid crystals displays.The relationship between the HTP values and structure was summarized,which will lay a theoretical foundation for the design of new chiral dopants.
