抜粋

We successfully improved the prediction accuracy of the driving lifetime in organic light emitting diodes based on numerical fitting of the luminous degradation curves and the decoupling of the self-heating effect from coulombic effects. Model phosphorescent multilayer OLEDs with CBP:Ir(ppy)3 emission layers are used.
