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.

Microdisplays are tiny, high-resolution electronic displays, designed for use in magnifying optical systems such as HDTV projectors and near-eye personal viewers. As a result of research and development into this field, Microdisplays are incorporated in a variety of visual electronics, notably new 3G portable communications devices, digital camera technologies, wireless internet applications, portable DVD viewers and wearable PCs. Introduction to Microdisplays encapsulates this market through describing in detail the theory, structure, fabrication and applications of Microdisplays. In particular this book: Provides excellent reference material for the Microdisplay industry through including an overview of current applications alongside a guide to future developments in the field Covers all current technologies and devices such as Silicon Wafer Backplane Technology, Liquid Crystal Devices, Micromechanical Devices, and the emerging area of Organic Light Emitting Diodes Presents guidance on the design of applications of Microdisplays, including Microdisplays for defence and telecoms, from basic principles through to their performance limitations Introduction to Microdisplays is a thorough and comprehensive reference on this emerging topic. It is essential reading for display technology manufacturers, developers, and system integrators, as well as practising electrical engineers, physicists, chemists and specialists in the display field. Graduate students, researchers, and developers working in optics, material science, and telecommunications will also find this a valuable 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

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.

An electroluminescent display panel of the cross-grid-matrix-type was fabricated on a 10-3/4 x 10-3/4-inch glass substrate using improved vacuum deposition procedures and a high brightness manganese-doped ZnS phosphor. This panel contained 256 x 256 active elements within an area of approximately 7 x 7 inches. Linear resolution was 36 elements per inch with a cross-conductor width of 0.020 inch and a separation of 0.007 inch. The display panel was successfully used as a viewing screen for rear-projected images. The brightness-voltage relationship of the thin film phosphor was such that a cross-suppression ratio in excess of 10,000 to 1 was achieved with an excited element brightness of 100 ft-L. Performance measurements indicated that the optimum drive frequency was about 15 kHz. For pulsed operation, a burst frequency of 37.5 Hz, a carrier frequency of 15 kHz, and a duty cycle of 0.25 percent gave an average brightness of a few foot-Lamberts. Useful operating lifetime of several hundred hours under the above conditions was indicated by preliminary data. The variation in brightness uniformity over a group of cells near the center of the panel was less than 7 percent at an average brightness level of 16 ft-L.A brightness reduction of about 12 percent was observed at a single cell when the contacting configuration was varied on the stannic oxide electrode.

Liquid crystals and electroluminescent organic materials have a wide commercial application in flat panel displays, in products such as clocks, navigational aids and laptop computers. Traditionally there has been a divide between the two fields of organic materials research and industrial activity. This book aims to bridge that gap and provide a standard reference work for all those involved. Starting with the first prototype and moving chapter by chapter through developments to the present day, Flat Panel Displays: Advanced Organic Materials describes the display type device specifications and material development. With clear descriptions and diagrams, the reader is presented with the fundamental properties of liquid crystals and electroluminescent organic compounds, along with the mode of operation of the displays using them. Written in a non-mathematical way, this book will be welcomed by chemists, physicists and materials scientists in both industry and research.
