LCDs are today the most important flat panel display and their development shows no sign of slow-down. This book aims to describe the trends, challenges and potential solutions of this exciting technology to young scientists and engineers working on liquid crystal displays and in its numerous related fields. The book targets not only liquid crystal experts but also newcomers. The extensive list of references and a discussion of the latest developments and challenges serve this aim. Many recent state-of-the-art technologies are introduced in this book. Special emphasis is put on display quality, such as image sticking, contrast ratio and colour hue which have not been sufficiently dealt with in other books. Moreover, future trends and applications of liquid crystals materials and LC-devices following historical development and how they affect society are discussed. Of particular interest, emerging applications such as gas sensors and smart windows are covered.
An unprecedented look into the basic physics, chemistry, and technology behind the LCD Most notably used for computer screens, televisions, and mobile phones, LCDs (liquid crystal displays) are a pervasive and increasingly indispensable part of our lives. Providing both an historical and a business-minded context, this extensive resource describes the unique scientific and engineering techniques used to create these beautiful, clever, and eminently useful devices. In this book, the history of the science and technology behind the LCD is described in a prelude to the development of the device, presenting a rational development theme and pinpointing innovations. The book begins with Maxwell's theory of electromagnetism, and the ultimately profound realization that light is an electromagnetic wave and an electromagnetic wave is light. The power of mathematical physics thus was brought to bear upon the study of light, and particularly the polarization of light by material bodies, including liquid crystals. After a brief historical description of polarization, a physical interpretation provides substance to the mathematical concepts. Subsequent chapters cover: Thermodynamics for liquid crystals The Maier-Saupe mean field, phenomenological, static continuum, and dynamic continuum theories The transistor and integrated circuit Glass, panels, and modules The calculus of variations The active matrix Semiconductor fabrication The global LCD business Additionally, the book illustrates how mathematics, physics, and chemistry are put to practical use in the LCDs we use every day. By describing the science from an historical perspective and in practical terms in the context of a device very familiar to readers, the book presents an engaging and unique view of the technology for everyone from science students to engineers, product designers, and indeed anyone curious about LCDs. Series Editor: Anthony C. Lowe, The Lambent Consultancy, Braishfield, UK 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.
A liquid-crystal display (LCD) is a flat-panel display or other electronically-modulated optical device that uses the light-modulating properties of liquid crystals. Liquid Crystal Displays are already widely used in consumer electronics, but research and development is still ongoing. The shifting focus of research follows a pattern of improved definition, increased display size, wider viewing angles and faster responses, with improvements in each area influencing the next. There is also growing interest in the use of liquid crystal materials in novel applications including sensing devices, spatial modulators and light-shielding windows.
Liquid crystals have attracted scientific attention for potential applications in advanced devices. Display technology is continuously growing and expanding and, as such, this book provides an overview of the most recent advances in liquid crystals and displays. Chapters cover such topics as nematic liquid crystals, active matrix organic light-emitting diodes, and tetradentate platinum(II) emitters, among others.
Liquid Crystal Display Drivers deals with Liquid Crystal Displays from the electronic engineering point of view and is the first expressively focused on their driving circuits. After introducing the physical-chemical properties of the LC substances, their evolution and application to LCDs, the book converges to the examination and in-depth explanation of those reliable techniques, architectures, and design solutions amenable to efficiently design drivers for passive-matrix and active-matrix LCDs, both for small size and large size panels. Practical approaches regularly adopted for mass production but also emerging ones are discussed. The topics treated have in many cases general validity and found application also in alternative display technologies (OLEDs, Electrophoretic Displays, etc.).
Polymers for Light-Emitting Devices and Displays provides an in-depth overview of fabrication methods and unique properties of polymeric semiconductors, and their potential applications for LEDs including organic electronics, displays, and optoelectronics. Some of the chapter subjects include: • The newest polymeric materials and processes beyond the classical structure of PLED • Conjugated polymers and their application in the light-emitting diodes (OLEDs & PLEDs) as optoelectronic devices. • The novel work carried out on electrospun nanofibers used for LEDs. • The roles of diversified architectures, layers, components, and their structural modifications in determining efficiencies and parameters of PLEDs as high-performance devices. • Polymer liquid crystal devices (PLCs), their synthesis, and applications in various liquid crystal devices (LCs) and displays. • Reviews the state-of-art of materials and technologies to manufacture hybrid white light-emitting diodes based on inorganic light sources and organic wavelength converters.
