Abstract

We propose a novel n-type a-Si:H TFT pixel circuit which is proper to AMOLED display for the large size and high resolution. Proposed pixel circuit will be suit to panel for the high resolution because of different threshold sampling method. Driving method of proposed pixel circuit is very simple like an AMLCD. Our simulation indicates that the proposed pixel circuit can compensate the Vth shift and IR rising of power line so that provide better quality image.
