In this paper, the transistors with excellent V TH uniformity could be fabricated by tuning oxygen content inside device. the V TH deviation of TFTs in panel is only 0.57V. Moreover, the devices we characterized show high reliability even long‐term stress. Finally, we demonstrated the 31‐inch 4K2K top emission OLED employing the a‐IGZO TFTs.
