Fully-Printed Flexible Indium-Tin-Oxide Thin-Film Transistors and Logic Circuits

Fabrication of metal oxide thin-film transistors (MO TFTs) using the inkjet printing process has attracted great interest in low-cost and large-area electronic devices. However, to develop fully-printed flexible MO TFTs with superior electrical performance remains challenging. In this study, we achieve fully-printed flexible indium-tin-oxide (ITO) TFTs and logic inverters on bendable glass and ultrathin polyimide (PI) film substrates with outstanding electrical performance and excellent stability. This cost-effective and reliable strategy enables the printed MO-TFTs for applications in flexible and wearable electronics.
