A Novel SPICE Compatible Current Model for OLED Circuit Simulation

In this paper we propose a new equivalent circuit model of organic light emitting device (OLED). The physicalbased model is considering the effect of high built-in voltage existing between the organic materials and the effect of non-ideal ohmic occurring at the contact between metal and organic. Compared with the measured IV data of RGB OLED samples and the result of conventional OLED model, the new one successfully shows the physical meaning and simulation accuracy. This model is SPICEcompatible and can be incorporated into circuit simulation without numerical difficulties.
