Thin Film Transistor - Basic Principles and Commercial Status

Abstract

Thin Film Transistor, a semiconductor device, is now widely used in the field of displays, especially LCD. A correct understanding of the nature of various types of TFTs and their current situation in commercial market has a significant positive influence on obtaining the reliable prediction and economic benefits of the display industry or even other potential markets that have not received significant attention. The key characteristics of some representative TFT and their historical development process is introduced in this paper. Then the commercial application of TFT is discussed regarding display industry and other minor field. Finally, some possible future trends and relevant challenges are discussed.
