英文摘要	the luminance decays of organic light-emitting diodes (oleds) are investigated with initial luminance of 1000 to 20 000 cdm(-2) through a scalable coulombic degradation and a stretched exponential decay. we found that the estimated lifetime by scalable coulombic degradation deviates from the experimental results when the oleds work with high initial luminance. by measuring the temperature of the device during degradation, we found that the higher device temperatures will lead to instabilities of organic materials in devices, which is expected to result in the difference between the experimental results and estimation using the scalable coulombic degradation.
