Book Description :

Recent improvements in LED technology have made them as ubiquitous as cell phones. In fact, LEDs light up almost all cell phones screens. The technology’s myriad applications and low energy use have made it nearly impossible to get through daily chores without coming in contact with LEDs. Probable advances include increased ability of the technology to support more efficient lighting and enhanced communications. With balanced coverage of the basics and future developments, Introduction to Light Emitting Diode Technology and Applications takes you on a tour of the LED evolution. The book begins with a brief history of the effort to enable the device that generates light through modern organic LEDs and reviews the fundamentals and principles of light prior to a detailed explanation of how LEDs generate different colors. After forming this basic foundation, the book examines the key LEDs in lighting and communications. It then discusses the latest opportunities and advancements in high brightness (HB) LED technology, solid state lighting, and handheld electronic applications. As we approach a new decade the role of LEDs is literally set to explode, with organic light emitting diodes emerging as a leading next generation technology for electronic displays and lighting. Challenges still exist, including light extraction, luminosity, and white light generation, not to mention non-technical obstacles such as IP disputes and the lack of standards. This book provides a foundation for resolving these issues and developing new applications for LEDs in the promising general illumination market.

Book Description :

The book focuses on various "substrate independent, large throughput" technologies: techniques that are able to build electronics on cheap, low cost, flexible and temperature sensitive substrates, like PEN or other plastic foils, and using inexpensive and large throughput methods like printing. Most of these technologies, in fact, have the potential to enable the revolutionary applications that will be discussed in the book. The book therefore goes beyond "organic" technologies, i.e. technologies that use functional organic materials (namely semiconductors), to explore a broader and even more interesting area of research. The book presents a comprehensive landscape of the new applications enabled by substrate independent, high throughput electronic technologies and their business potential. It explains the link between innovation in technology and in products. It also provides the reader with a clear understanding of the technology and the research challenges in the field. The book is divided in two parts. The first is devoted to applications where the most important selling point is large area. To this domain belong roll-up, flexible and emissive displays based on organic devices (used in backplanes or as display medium), unobtrusive electronics enabling ambient intelligence applications, and the increasingly important photovoltaic applications. The second part is devoted to applications where cost reduction is the main factor. RFIDs, smart labels, organic sensors and printed sensor system belong to this domain. A chapter is devoted to each different application. Each chapter is originally developed for the book by (a group of) world-wide recognized experts in the specific field of application.
