Abstract
When a blue polymer OLED device is driven under DC constant current the electroluminescence decays over time. Over the last two years there have been large advances in the time taken for the luminescence to fall to 50% of its original value. This is in part due to an improved recognition and understanding of the degradation mechanisms involved in the luminescence decay. Measurements made from devices during lifetest have identified a number of characteristic degradation-related changes to the device and to the light-emitting polymer. In this paper we will compare these degradation signatures together with the material properties between light-emitting polymers which have been designed to give a long DC-driven lifetime and a class of polymers which have been specifically designed to give a long lifetime under pulsed driving schemes.
