OLED Display Fundamentals and Applications

Series Editor’s Foreword

I have long aspired to publish a book on OLED technology in this series. From the beginning, the problem I encountered was that the technology was so new and was developing so rapidly that any book written would have been out of date before it was published. Although the technology is still developing at a prodigious rate, it has reached a level of maturity that at last makes possible the publication of a book covering all aspects of OLED technology from a fundamental description of light emission from OLED materials through TFT design to manufacturing techniques and applications not just to displays but also to lighting. Books previously published in the field have essentially been collections of research papers. Useful as such books are, they do not fulfill the objectives of the Wiley-SID series, so I hope that those who require a text covering all aspects of this important technology will consider this latest book in the series to have been well worth the wait.

To provide the reader with a précis of the scope of this book, after an introductory chapter which focuses on early OLED-based products, Chapter 2 contains a brief history of OLED development and then goes on to describe in detail and on the basis of actual device structures the electronic and thermodynamic fundamentals of light emission from small molecule and polymeric, singlet and triplet OLED materials, the mechanisms of charge injection, transfer and recombination, electron and optical efficiency, ...
