题目：Flexible TFTs for Displays
Plastic AMOLED displays are of increasing attention recently for mobile applications. The TFT backplane on polyimide (PI) substrates are widely used for smartphone displays. We developed a nonlaser detach process of PI substrate from carrier glass by using a GO/CNT buffer which is being used for highly robust oxide TFTs and TFT circuits in our lab . The bulk accumulation oxide TFTs exhibiting both high on-currents and uniform threshold voltage can be applied to high resolution displays and high speed TFT circuits . In this talk I will discuss our recent research results on TFTs and TFT circuits on PI substrates. We have also developed highly robust TFTs using TFTs in neutral plane  and high mobility a-IGZO TFTs on PI substrate by introducing top interface engineering [4,5]. The performance, electrical stability and mechanical stability will be introduced.
