In this paper, the transistors with excellent VTH uniformity could be fabricated by tuning oxygen content inside device. the VTH 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.

In this paper, we have demostrated high PBTS top‐gate self‐aligned IGZO TFTs by employing different H‐incorration process. Through optimization processes, PBTS is improved to 0.29 V and Vth deviation on Gen. 4.5 glass is 0.4V. Finally, 31‐inch OLED TV employing GOA circuit applied by this optimized backplane was successfully demonstrated.
