Open publisher page 1 citations

Abstract

For active matrix organic light emitting diode (AMOLED) pixel designs, co-simulations of OLED and TFTs are necessary and requires a dedicated OLED model. We report our efforts in developing a physics-based compact model of OLEDs for accurate reproduction of their electrical and luminescence characteristics. The model's applicability in SPICE with smooth derivatives are demonstrated by AMOLED pixel simulations with light intensity as outputs.
