Opticals Effects in Liquid Crystals by I. Jánossy Pdf

In 1988 physicists and chemists commemorated the centenary of the discovery of the first liquid crystals. Fora long period after this discovery, although many significant results were found, liquid crystal research remained a marginal topic of condensed matter physics. The situation changed in the sixties. At that time the remarkable electro-optical properties of liquid crystals were recognized and found soon widespread application in numeric displays. From a more fundamental point of view, the interest in disordered systems. increased in general at the same time. Liquid crystals represented an important dass of such systems. Among others, phase transitions, hydrodynamics and topological defects occurring in them attracted considerable attention. The connection between the liquid-crystalline state and the structure of biological membranes stimulated a Iot of works also. In the present volume we discuss a relatively new and rapidly developing branch of the fi. eld, namely nonlinear optical effects in liquid crystals. Optical studies have always played a signifi. cant role in liquid crystal science. Research of optical nonlinearities in liquid crystals began at the end of the sixties. Since then it became a powerful tool in the investigation of symmetry properties, interfacial phenomena or dynamic behaviour. Furthermore, several new aspects of nonlinear processes were demonstrated and studied extensively in liquid crystals. The subject covered in this book is therefore of importance both for liquid crystal research and for nonlinear optics itself. The term "nonlinear optics" is used here in a broad sense.

Structure and Properties of Liquid Crystals by Lev M. Blinov Pdf

This book by Lev M. Blinov is ideal to guide researchers from their very first encounter with liquid crystals to the level where they can perform independent experiments on liquid crystals with a thorough understanding of their behaviour also in relation to the theoretical framework. Liquid crystals can be found everywhere around us. They are used in virtually every display device, whether it is for domestic appliances of for specialized technological instruments. Their finely tunable optical properties make them suitable also for thermo-sensing and laser technologies. There are many monographs written by prominent scholars on the subject of liquid crystals. The majority of them presents the subject in great depth, sometimes focusing on a particular research aspect, and in general they require a significant level of prior knowledge. In contrast, this books aims at an audience of advanced undergraduate and graduate students in physics, chemistry and materials science. The book consists of three parts: the first part, on structure, starts from the fundamental principles underlying the structure of liquid crystals, their rich phase behaviour and the methods used to study them; the second part, on physical properties, emphasizes the influence of anisotropy on all aspects of liquid crystals behaviour; the third, focuses on electro-optics, the most important properties from the applications standpoint. This part covers only the main effects and illustrates the underlying principles in greater detail. Professor Lev M. Blinov has had a long carrier as an experimentalist. He made major contributions in the field of ferroelectric mesophases. In 1985 he received the USSR state prize for investigations of electro-optical effects in liquid crystals for spatial light modulators. In 1999 he was awarded the Frederiks medal of the Soviet Liquid Crystal Society and in 2000 he was honoured with the G. Gray silver medal of the British Liquid Crystal Society. He has held many visiting academic positions in universities and laboratories across Europe and in Japan.

Liquid Crystal Displays by Ernst Lueder Pdf

The special feature of the book is the in depth treatment of both the electro-optic effects and the addressing schemes of liquid crystal displays elucidating their interdependence. After basic explanations readily understandable for students and stimulating for engineers, physicists and chemists, the reader is gradually led to the latest developments such as vertically aligned and mixed mode TN-displays, compensation foils, multiple line and low power addressing, transistor driven LCOS-devices with DRAM and SRAM addressing and TFT-addressing of transmissive displays with a 92% aperture ratio. The results are analytically derived and not merely stated to enhance insight and the capability to tailor displays to individual needs or to perform novel designs. Towards this aim the propagation of light with the help of Jones vectors, four different characterizations of the state of polarization and the operation as well as the passive and active matrix addressing of all LCDs, like nematic, polymer dispersed, guest host and bistable devices is explained. Besides the mainstream twisted and supertwisted nematic LCDs attention is drawn to bistable ferroelectric, chiral nematic and modified nematic LCDs as they are most promising for future portable low power systems. Tables on display formats and units for the measurement of displays finally render the book suitable as a reference for experts working in the field and as a textbook for universities or display courses. The forefront of research is reached by the treatment of plastic substrates, the replacement of vacuum processes by less expensive printing and low temperature fabrication of a-Si- and poly-Si-TFTS.
