有机薄膜晶体管阵列面向电子纸像素设计

Pixel Design of Organic Thin Film Transistor Array

讨论了有机薄膜晶体管(Organic Thin Film Transistor,OTFT)作为开关器件来驱动电子纸的像素设计,特别是像素电路结构、HSPICE模拟用模型参数和像素平面结构。讨论了有机薄膜晶体管制造过程,并用HSPIC模拟分析了有机薄膜晶体管结构和存贮电容大小对像素波形的影响,结果表明TFT结构的选择依赖于存贮电容的大小。

As a switch device of the pixel,the Organic Thin Film Transistor（OTFT） has good IDS-VGS curve.This paper describes the pixel circuit,model parameter for HSPICE simulation and the pixel layout.In order to verify the influence of storage capacitor and TFT structure on the pixel waveform,the pixel waveform was simulated by HSPICE.The OTFT process is studied in this paper.Result shows that OTFT structure is selected according to the storage capacitor for different products.The OTFT process is suitable for flexible display.
