摘　　要：液晶显示如今已经成为信息显示工业的主流技术,广泛应用于小尺寸显示器,如计算器、手机、数码相机等;中尺寸显示器,如笔记本电脑和桌面显示器;大尺寸显示器,如直视型电视和投影电视。传统液晶如向列相液晶,胆甾相液晶等,虽对外电场有着快速的响应时间(毫秒量级),但随着人们生活水平的提高,追求更高质量的显示,这就要求液晶具有更快的响应速度以满足高分辨率动态显示。本文系统描述了影响液晶响应时间的要素,重点介绍了几种具有快速响应机制的新型液晶体系,如聚合物稳定蓝相液晶、铁电液晶、铁电向列相液晶和序参数电控效应。最后,展望了快速响应液晶在显示器件和光子学器件中的应用前景。Liquid crystal display is now the dominant technology for information displays,which is widely used in small size displays,such as calculators,mobile phones,and digital cameras;medium size displays,such as laptops and desktop monitors;large size displays,such as direct-view TV and projection TV.Although traditional liquid crystals,such as nematic liquid crystals and cholesteric liquid crystals,exhibit fast response to electric field,higher quality displays are pursued along with the improvement of the people’s living standards.It requires liquid crystals of faster response to satisfy the dynamic display of high resolution.This paper systematically summarizes the factors affecting the LC response,and emphasizes several kinds of new liquid crystals of fast responsiveness,such as polymer stabilized blue phase liquid crystal,ferroelectric liquid crystal,ferroelectric nematic liquid crystal and electric modulation of order parameters.Finally,we rationally anticipate the promising applications of fast response liquid crystals in displays and photonic devices.
