A new OLED SPICE model for pixel circuit simulation in OLED-on-silicon microdisplay design
一种新的应用到硅基有机发光二极管微显示像素电路仿真的OLED SPICE模型

A new equivalent circuit model of Organic-Light-Emitting-Diode (OLED) is proposed in this paper. As the single-diode model is able to approximate OLED behavior as well as multiple-diode model, the new model will be built based on it. In order to make experimental and simulated data have a good agreement, the constant resistor is changed to exponential resistor in the new model. Compared with the measured data and the results of the other two OLED SPICE models, the simulated I-V characteristics of the new model match the measured data much better. This new model can be directly incorporated into SPICE circuit simulator and presents good accuracy in the whole operating voltage.
