Design of an Organic Pixel Addressing Circuit for Active-Matrix OLED Displays

In this paper, we present a new model for an organic pixel addressing circuit based on four-transistor configuration. The proposed circuit doesn’t have the problems of regular configurations which are based on four-thin film transistors (TFT). Circuits based on four-TFT have many advantages, but the only problem is the existence of current peaks at the beginning of each pixel luminescence. Both 4-TFT based configuration and proposed one were simulated using HSPICE. Simulation results indicate the superiority of the proposed method compared with existing technique.
