Preface

Welcome to AM-FPD ´13, the 20th International Workshop on Active-Matrix Flatpanel Displays -TFT Technologies and FPD Materials- (AM-FPD ´13) and to the Avanti Kyoto Hall, Ryukoku University, Japan. Sponsored by the Japan Society of Applied Physics and technically sponsored by Electronics and Photonics Division and Japan section in The Electrochemical Society (ECS), The Institute of Electrical and Electronics Engineers (IEEE) Electron Devices Society, AM-FPD ´13 marks the twentieth anniversary event in the workshop series. Since its inception in 1994, the workshop has been providing important opportunities for people engaged in the research and development of systems, devices, materials, processes for FPDs (Flat Panel Displays), and photovoltaics. The active-matrix display and solar cells are the key devices for facilitating the green and safety society.
