Analytical model for current distribution in large-area organic light emitting diodes with parallel metal grid lines
article
In this study, an analytical solution for the current distribution of a large-area organic light emitting diodes (OLEDs) with parallel equidistant gridlines is derived. In contrast to numerical methods, this analytical solution allows for a very quick scan of the OLED design space, even for very large OLEDs, providing insight how different model parameters affect each other. The assumptions within the analytical derivation are verified with finite element simulations of the same OLED. Furthermore, the analytically calculated light distribution was experimentally verified by measuring the light distribution on a large-area OLED.
