Abstract / Description of output

Positively doped, intrinsic, negatively doped organic light-emitting diodes (PIN-OLEDs) have been shown to exhibit high efficiency and a long lifetime compared to conventional small-molecule OLEDs (SM-OLEDs). The improved performance of PIN-OLEDs makes them attractive for use in display applications. Knowledge of the electrical load exhibited by these devices is used to develop an equivalent electrical-circuit model. Such models are used by circuit designers to assist with the precise design of active-matrix-display driver circuits used in such applications. In this paper, the development of a SPICE model for a top-emitting PIN-OLED stack is reported.
