In the commonly-used EDA software, there is no equivalent circuit model of top-emitting OLED for SPICE, so it is difficult while the OLED pixel driving circuits are designed such as in microdisplay applications. To solve the problem, its SPICE model of top-emitting OLED was studied in this paper. Three models including the diode-connected NMOS model, the single-diode model, and the double-diode paralleled model are discussed and their simulation results from EDA software HSPICE are compared. Results show that the fitted errors obtained from the diode-connected NMOS model is the smallest, but its simulated errors are the largest. The fitted errors and the simulated errors obtained from the single-diode model are also large. However, small fitted errors and simulated errors got from double-diode paralleled model show that this model satisfies the application of the designing for OLED pixel driving circuits.
