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.

In this paper, effects of carbon source on the biofilm cultivation were investigated by adding or not adding liquid carbon source with corncob used as solid carbon source and biocarriers. By adding or not adding glucose in the culture solution, effects of carbon source on the biofilm cultivation were determined by measuring COD, NO3--N, NO2--N and pH of culture solution after reaction. Results showed that adding liquid carbon source was beneficial to forming the biofilm with good denitrification performance, however, not adding carbon source could only form biofilm with bad denitrification performance and denitrification reaction only proceeded to the step of NO2--N after reaction. Results indicated that it was necessary to add liquid carbon source for the forming biofilm with good denitrification performance on the surface of corncob biocarriers.
