与通常的液晶显示器(LCD)基板的“摩擦”处理相比，光对准具有显著的优势，因为它是一种高分辨率的非接触式方法。这本书的作者最近开创了一种新技术，即偶氮染料的光诱导扩散重定向，它不涉及任何分子的光化学或结构转化。这导致了光致对准薄膜的坚固和具有良好的对准性能，使它们特别适合于新一代液晶器件。液晶材料的光对准包括最先进的技术和关键应用，以及作者自己的光对准扩散模型。这本书旨在刺激液晶光取向领域的新研究和开发，并通过这样做，使该技术能够用于大规模LCD生产。主要特点：提供了对光对准机制的全面检查。考察了液晶在光取向过程中的性质，特别是对其化学结构和稳定性的影响。认为最有用的光敏材料和制备方法适合于液晶光定向。介绍了几种用于液晶光取向的方法。比较了光对准技术在细胞内图案化偏振器和相位延迟器、透射式和微型显示器、安防和其他液晶器件中的各种应用。通过其跨学科的方法，这本书是针对广泛的实践电气工程师，光学工程师，显示技术专家，材料科学家，物理学家和化学家工作在液晶设备的发展。它还将吸引学习液晶或显示技术课程的研究人员和研究生。信息显示协会(SID)是一个国际性的协会，其宗旨是鼓励信息显示领域各方面的发展。与协会的目标相辅相成的是，Wiley-SID系列旨在从专业层面解释信息显示技术的最新发展。该系列的广泛范围涉及信息显示的所有方面，从技术方面到系统和原型，再到标准和人体工程学
Photoalignment possesses significant advantages in comparison with the usual ‘rubbing’treatment of the substrates of liquid crystal display (LCD) cells as it is a non-contact method with a high resolution. A new technique recently pioneered by the authors of this book, namely the photo-induced diffusion reorientation of azodyes, does not involve any photochemical or structural transformations of the molecules. This results in photoaligning films which are robust and possess good aligning properties making them particularly suitable for the new generation of liquid crystal devices. Photoalignment of Liquid Crystalline Materials covers state-of-the-art techniques and key applications, as well as the authors’ own diffusion model for photoalignment. The book aims to stimulate new research and development in the field of liquid crystalline photoalignment and in so doing, enable the technology to be used in large scale LCD production. Key features: Provides a full examination of the mechanisms of photoalignment. Examines the properties of liquid crystals during photoalignment, with particular reference made to the effect on their chemical structure and stability. Considers the most useful photosensitive materials and preparation procedures suitable for liquid crystalline photoalignment. Presents several methods for photoalignment of liquid crystals. Compares various applications of photoalignment technology for in-cell patterned polarizers and phase retarders, transflective and micro displays, security and other liquid crystal devices. Through its interdisciplinary approach, this book is aimed at a wide range of practising electrical engineers, optical engineers, display technologists, materials scientists, physicists and chemists working on the development of liquid crystal devices. It will also appeal to researchers and graduate students taking courses on liquid crystals or display technologies. 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
