N2 - A novel current driving pixel circuit for active-matrix organic light-emitting diodes (OLEDs) based on organic TFTs (OTFTs), is presented and verified by HSPICE simulation. The simulation results show that the proposed pixel circuit, which is a current-mirror structure consisting of five organic TFTs and one capacitor, has current nonuniformity of less than 2.5% throughout the entire data range. Also, variation in OLED current due to threshold voltage degradation of organic TFTs is effectively compensated to reliable values.
