This book discusses recent developments in electroluminescent (EL) displays, in particular thin-film EL displays, which are all-solid emissive displays with fast response, wide viewing angle, high resolution, wide operating temperature ranges and good display qualities. First, the characteristics of four types of EL devices are presented, and the physics of ac thin-film EL devices are detailed, including ideal models, measuring and evaluation methods, high-field electronic transport and properties of phosphor materials. The book emphasizes recent developments in phosphor materials for color thin-film EL devices based on ZnS, SrS, CaS and CaGa2S4, and multicolor thin-film EL panels in four-panel structures. Other important features discussed are drive methods and reliability issues.

An electroluminescent (EL) material is one that emits electromagnetic (EM) radiation in the visible or near visible range when an electric field is applied to it. EL materials have a vast array of applications in the illumination and displays industries, from cheap and energy efficient lighting to large high resolution flat panel displays.

This book is a comprehensive review of the present state and future prospects of the displays used in entertainment television sets and in data terminals and personal computers. Such a treatment was deemed necessary because of the importance of displays in possible future communications services incorporating computer graphics and video. A few main conclusions are drawn. One is that modest-sized flat-panel displays will become commonplace where space is at a premium, such as on desktops and in kitchens or bedrooms. It is another matter to stretch these displays to several feet on a side, however. For the next five to ten years, these larger displays will mostly rely on optical projection. Thereafter, plasma techniques could well make large-area, flat-panel TV displays affordable.

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. The detailed chapters on classification, theory, chemical structure, physical properties and surface alignment of liquid crystals facilitate the basic understanding of the science behind LCDs and other uses of liquid crystals. The chapters on liquid crystal polymers and lyotropic liquid crystals, give deep insight into these areas. The potential uses and applications are also described in detail.

Output Hardcopy Devices provides a technical summary of computer output hardcopy devices such as plotters, computer output printers, and CRT generated hardcopy. Important related technical areas such as papers, ribbons and inks, color techniques, controllers, and character fonts are also covered. Emphasis is on techniques primarily associated with printing, as well as the plotting capabilities of printing devices that can be effectively used for computer graphics in addition to their various printing functions. Comprised of 19 chapters, this volume begins with an introduction to vector and raster plotters, presented from the viewpoint of the user. The general considerations that apply to these types of hard copy devices are discussed, along with the problems and pitfalls that the user may encounter. The vector plotters cited are the drum and flatbed types that use pens to write on some type of medium, such as paper. Subsequent chapters focus on plotters and hard copy imaging technologies, and those that use CRTs as the image source, with cameras as the primary means for producing the hard copy. Impact and non-impact printing technologies as well as other technology areas that are very important to plotters and printers are also examined. This book should be of value to students and researchers interested in printing and computer graphics.
