Abstract:	New pixel circuit designs for active matrix organic light emitting diodes (AMOLEDs), based on the low-temperature polycrystalline silicon thin-film transistors (LTPS-TFTs) were proposed and verified by SPICE simulation and fabrication results. Threshold voltage compensation pixel circuits consisting of five TFTs, one additional control signal, and one storage capacitor were used to enhance display image uniformity. The simulation and measured results show that this pixel circuit has high immunity to the variation of poly-Si TFT characteristics. (c) 2006 Elsevier Ltd. All rights reserved.
