Highly bendable Inorganic TFT Array for Sensor Applications

Speaker: Manabu Ito | Company: Toppan | Date: 9-10 March 2022 | Full Presentation

Flexible thin film transistors (TFT) attract a lot of attention due to its applicability to foldable smartphones, IoT sensors, and photodetectors. For this application, organic TFT had been regarded as a most promising candidate thanks to its soft nature of the component materials. However, organic TFT suffers from its low mobility, poor stability and immature production process.

In this talk, we would like to introduce our highly bendable IGZO TFT. Without employing the neutral plane concept, the TFT can withstand one million times bending tests at a curvature radius of 1 mm for the first time. After one million times bending tests, any noticeable deterioration in device characteristics are not observed. We see a big potential for the application for flexible sensor devices.
