From laptop computers and mobile phones to digital cinema, Liquid Crystal Displays (LCDs) are integral components in an increasing array of highly desirable consumer electronics and communication devices, and are already the predominant technology used in flat panel displays. This inter-disciplinary book is intended as an introductory guide to the fundamental properties of liquid crystals and their applications in display and photonic devices, providing a basic understanding of the physics, optics, electro-optics, and material aspects for state-of-the-art display and photonic devices. Fundamentals of Liquid Crystal Devices includes: A comprehensive overview of LCDs including liquid crystal physics, electro-optical properties, simulation techniques and display and photonic applications. Numerous examples and case studies, solved problems and challenging homework conundrums starting with basic physics and gradually introducing advanced device concepts and structures. The principles for designing advanced specialist transmissive, reflective, and transflective liquid crystal displays. Chapters on emerging technologies such as tuneable liquid crystal photonic devices including laser beam steering, light switches for telecommunication and tunable-focus lenses. Fundamentals of Liquid Crystal Devices is a valuable resource for advanced undergraduate and graduate students following display systems courses, who will benefit from its systematic approach. The introduction of advanced device concepts and structures means that display engineers, scientists, and technicians active in the field can also utilise this unique resource, as can developers of a wide range of systems and applications. The Society for Information Display (SID) is an international society, which has the aim of encouraging the development of all aspects of the field of information display. Complementary to the aims of the society, the Wiley-SID series is intended to explain the latest developments in information display technology at a professional level. The broad scope of the series addresses all facets of information displays from technical aspects through systems and prototypes to standards and ergonomics

This book reviews comprehensively the technological, scientific, artistic and medical applications of liquid crystals. It starts with the basics of liquid crystals and covers electro-optical, thermo-optical, colour, polymeric, lyotropic, and scientific applications of liquid crystalline materials. It discusses the fabrication and operational principles of a full range of liquid crystal displays including dynamic scattering, twisted nematic, supertwisted nematic, dichroic, smectic A, ferroelectric, polymer dispersed, light valve, active matrix, etc., in detail. It also covers the emerging applications of liquid crystals such as optical computing, nonlinear optics, decorative and visual arts. Classification, theory, chemical structure, physical properties and surface alignment of liquid crystals have detailed chapters to facilitate the basic understanding of the science behind LCDs and other uses of liquid crystals. The chapters, liquid crystal polymers and lyotropic liquid crystals, give deep insight into these areas. The potential uses and applications are also described in detail.

The usefulness of optical devices, whose sensors consist of cholesteric liquid crystal combinations, is directly dependent upon the reproducibility of their color responses to changes in temperature and to electric fields. Many of the processes by which cholesteric liquid crystals lose their valuable optical properties were identified and steps taken to diminish or eliminate their effects. Oleyl cholesteryl carbonate, one of the essential components of field- and heat-sensitive liquid crystal mixtures, was found to decompose spontaneously to give CO and CO2 at a relatively small rate, which may still be too large in the case of applications involving sealed, evacuated systems. The thermal hysteresis observed in high temperature-sensitive liquid crystals was mainly dependent upon the material composition of the system and on the operating range. On shearing, cholesteric liquid crystal layers lost color intensity, but the wavelength of their maximum reflectance did not change appreciably. The rate of intensity recovery after cessation of shearing was linear with the logarithm of time. The main degradative process is brought about by the combined and cumulative influences of ultraviolet light, oxygen and air-borne particulates; as a result, the color-bearing cholesteric structure is changed into a non-colored texture and the color responses are lost. This drawback was remedied by incorporating ultraviolet energy absorbers and polymeric protectants into the liquid crystal combinations. With these modified systems the useful life of cholesteric liquid crystal sensing systems was prolonged by several months. (Author).

With their helical structure, cholesteric liquid crystals figure prominently in liquid crystal science. The selective reflection of light is their flagship property, and they offer a myriad of applications as advanced optical materials with multiscale properties. The cholesteric structure is also a ubiquitous design in the animal and plant kingdoms. This book contains eight contributions on fundamental investigations about defects, textures and structures of cholesteric materials, and experimental studies aimed at applications such as temperature sensors, head-up displays for improving automobile driving safety, or smart windows.
