This lecture covers thin-film transistors (TFT) and flat panel displays (FPD), discussing various TFT configurations such as top gate, bottom gate, and double gate TFTs, as well as the process flow for active matrix liquid crystal display (AMLCD) TFTs. It explains the operation of amorphous silicon TFTs, effective mobility, TFT regimes, transconductance, and threshold voltage shift. The lecture also delves into TFT instabilities, photosensitivity, performance factors, system integration, printed electronics, and challenges in TFT materials and performance optimization. Additionally, it explores metal oxide-based TFTs, heterojunction FET transistors with a-Si, and provides a bibliography for further reading.
