中文摘要：

非晶硅、非晶氧化铟镓锌、多晶硅薄膜晶体管是可用于设计AMOLED像素驱动电路的3种典型的薄膜晶体管（TFT）技术。文中基于3种TFT的模型，针对大尺寸、高分辨率的AMOLED，分别在典型的电压式驱动和电流式驱动像素电路进行了建模仿真，并对仿真结果做了分析和比较。该研究方法为像素电路的设计提供了一定理论依据。

英文摘要：

Active matrix organic light emitting diode （AMOLED） pixel circuits can be designed based on amorphous silicon, amorphous In-Ga-Zn-O and polycrystalline silicon thin film transistors. In this work, simulations and analysis have been conducted for typical voltage and current driving AMOLED pixel circuits in the three different TFT technologies. The analysis and comparison results provide important guidelines for selecting proper TFT technologies to design large-size and high-resolution AMOLEDs.
