摘要：
We have proposed and fabricated 3-TFT pixel circuit employing a fraction time annealing to improve a current stability for a-Si:H TFT based AMOLED backplane. The measurement results, after an electrical bias and temperature (60 degrees C) stress of 12 hours, show that OLED current is decreased by 23% in conventional 2-TFT pixel, while decreased by 6% in the proposed 3-TFT pixel because a negative bias can reduce V(TH) degradation of a-Si:H TFT itself.
