Abstract

A new pixel circuit using low-temperature polycrystalline-silicon (LTPS) thin-film transistors for Active Matrix Organic Light Emitting Diodes (AMOLEDs) is presented. The proposed current programming circuit without charging time problem at low gray level compensates for the threshold voltage variation of TFT as well as OLED luminance decay. The simulation results demonstrate driving current of this circuit is independent of the variation of TFT and maintain luminance for long term operation.
