title = "A new pixel circuit employing data reflected negative bias annealing and threshold voltage compensation for stable, uniform a-Si:H TFT AMOLED",
abstract = "We proposed 6 TFTs pixel can reduce VTH degradation of driving a-Si:H TFT by Data Reflected Negative Bias Annealing (DRNBA) and compensate VTH variation induced by non-uniform degradation of each a-Si:H pixel caused by its various emission history. The proposed pixel was proved by SPICE simulations. Although VTH of driving TFT was varied from 2.5V to 3.0V and 3.5V, the current of OLED was changed by only 1.5\% and 2.8\% in the emission period, respectively. During the negative bias annealing period, the negative VGS is applied to the driving TFT by using its own data signal. It is expected that the VTH shift of the driving TFT can be reduced effectively and the shifted VTH can be compensated in our new pixel, which can enable stable and uniform a-Si:H TFT AMOLED.",
