研究目的
To develop stable thin-film transistors (TFTs) with high mobility for large size 8K4K LCD TVs and high resolution OLED TVs, focusing on back channel etched (BCE) structure TFTs and self-aligned coplanar structure TFTs.
研究成果
The development of 85 inch 8K4K 120Hz AMLCD TV driven by GOA and BCE structure a-IGZO TFT with 4 mask processes, and 31 inch 4K2K top emission IJP AMOLED with self-aligned coplanar structure a-IGZO TFT, demonstrates the potential of oxide TFT technologies for high-end displays. Future work includes further optimization for uniformity and stability.
研究不足
The sensitivity of BCE structure TFTs to process conditions and the challenge of minimizing back channel damage during wet etching. The need for careful consideration of passivation layer deposition conditions to ensure TFT stability.
