Prospects of oxide TFTs approaching LTPS

Abstract

Oxide TFTs are becoming the mainstream backplane technology for high-resolution large screen displays, while LTPS TFTs are mostly used for high-end portable smart devices. Recent developments in oxide TFTs show high mobility exceeding 50 cm2/V·s, good stability characteristics comparable to LTPS, and integration on plastic substrates for a large range of flexible applications. With these technological advances, oxide TFTs can become a universal backplane solution for LCD and OLED displays.
