Alignment phenomena are characteristic of liquid crystalline materials, and understanding them is critically important in understanding the essential features and behavior of liquid crystals and the performance of Liquid Crystal Devices (LCDs). Furthermore, in LCD production lines, the alignment process is of practical importance. Alignment Technologies and Applications of Liquid Crystal Devices demonstrates both the fundamental and practical aspects of alignment phenomena in liquid crystals. The physical basis of alignment phenomena is first introduced in order to aid the understanding of the various physical phenomena observed in the interface between liquid crystalline materials and alignment layer surfaces. Methods for the characterization of surfaces, which induce the alignment phenomena, and of the alignment layer itself are introduced. These methods are useful for the research of liquid crystalline materials and devices in academic research as well as in industry. In the practical sections, the alignment methods used in the LCD production lines are introduced with various other trials for the alignment technologies. LCD performances are also discussed in relation to alignment phenomena. The authors have a wide range of experience in both academic research and in industry. This book will be of interest to researchers and engineers working in the LCD industry, and for physics and chemistry researchers studying liquid crystalline materials.

Sunlight readable transflective liquid crystal displays, used on devices from cell phones and portable media players, to GPS and even some desktop monitors, have become indispensable in our day-to-day lives. Transflective Liquid Crystal Displays is a methodical examination of this display technology, providing a useful reference to the fundamentals of the topic. Including thorough descriptions of the essential physics of transflective LCD technologies, the book also compares transflective LCD technology with alternatives, such as OLED displays, to enable display engineers to appropriately select the correct device for their particular application. Includes detailed descriptions of both pure transmissive and reflective LCDs, and the design considerations and performance of combining these into small mobile displays. Focuses on fundamental elements, such as double cell gap transflective LCDs, wide-viewing angle technology, light polarization and wide-view linear and circular polarizers, video rate display by colour sequential technologies, colour sciences and engineering, and backlights. Describes the latest LCD technologies, such as polymer-sustained surface alignment technology, and the possible trends which could be applied to transflective LCDs in the future. Its focus on the fundamentals of transflective liquid crystal displays makes this an ideal graduate text, while display engineers, scientists, developers and technicians working with this technology will also welcome this resource. 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

The Special Issue “Liquid Crystal Optical Devices” discusses recent developments in the rapidly advancing subject of liquid crystals (LCs). The book is composed of several contributions from researchers in the field of liquid crystals that deal with the broadly with aspects of optical devices ranging from a theoretical viewpoints to practical implications of the properties of LCs. This is the first Special Issue devoted solely to recent advances in the rapidly expanding subject of LCs, a unique class of substances that combines both ordered structures with quasi-liquid-like properties. This Special Issue offers a broad perspective of the present state of the art in design and an up-to-date account of the most recent advances and progress in the field of LCs, providing thorough coverage of the demonstrated optical devices and the comprehensive analysis needed by professionals and engineers in the field of LC. The material is carefully structured, providing readers with a solid foundation of the principles, capabilities, use, and limitations of LC optical devices. In addition, this book covers the principles, recent advances and future developments of liquid crystal beam steering devices as well as recent advances in adaptive liquid crystal lenses.

Liquid Crystal on Silicon (LCoS) has become one of the most widespread technologies for spatial light modulation in optics and photonics applications. These reflective microdisplays are composed of a high-performance silicon complementary metal oxide semiconductor (CMOS) backplane, which controls the light-modulating properties of the liquid crystal layer. State-of-the-art LCoS microdisplays may exhibit a very small pixel pitch (below 4 μm), a very large number of pixels (resolutions larger than 4K), and high fill factors (larger than 90%). They modulate illumination sources covering the UV, visible, and far IR. LCoS are used not only as displays but also as polarization, amplitude, and phase-only spatial light modulators, where they achieve full phase modulation. Due to their excellent modulating properties and high degree of flexibility, they are found in all sorts of spatial light modulation applications, such as in LCOS-based display systems for augmented and virtual reality, true holographic displays, digital holography, diffractive optical elements, superresolution optical systems, beam-steering devices, holographic optical traps, and quantum optical computing. In order to fulfil the requirements in this extensive range of applications, specific models and characterization techniques are proposed. These devices may exhibit a number of degradation effects such as interpixel cross-talk and fringing field, and time flicker, which may also depend on the analog or digital backplane of the corresponding LCoS device. The use of appropriate characterization and compensation techniques is then necessary.

This book focuses on the development of liquid crystal displays (LCDs) and liquid crystal materials (LCs) in Japan. The Committee of Organic Materials Research for Information Sciences of the Japan Society for the Promotion of Science (JSPS) planned the book to document essential LCD innovations and developments since the beginnings of the field-effect LCD technology in 1970. The book illustrates the remarkable effort and progress behind those flat, lightweight, and high-information-content LCDs that have become the indispensable human–machine interface for virtually all electronic devices. In contrast to other publications on this topic, the book illustrates the interdisciplinary character of the LCD technology and its crucial importance for technological progress of the field far beyond displays. It also gives insights into breakthrough innovations not revealed in other publications. Moreover, prospects for the development of LC research toward new fields of applications are provided. In line with its interdisciplinary character, the book targets researchers in basic science as well as engineers and researchers in industry.
