Abstract
A Novel pixel structure with a new threshold voltage compensation technique is proposed for large-size a-Si:H AMOLED panel application. The proposed pixel improves image quality with threshold voltage compensation and alleviates annealing technique for display-off time. Sensing the threshold voltage of driving TFT for 20-inch WUXGA panel is verified by the HSPICE simulation.
