51.1: Amorphous Indium‐Gallium‐Zinc‐Tin‐Oxide TFTs with High Mobility and Reliability

Abstract

A high‐mobility amorphous Indium‐Gallium‐Zinc‐Tin‐Oxide (a‐IGZTO) TFT was demonstrated. The new TFT achieved a large field effect mobility of ~24.7 cm 2 /Vs, which had a comparable reliability to the a‐IGZO TFT. Furthermore, 4K×2K AMOLED TV addressed by the a‐IGZTO TFT showed a good performance.
