摘要

Organic Light Emitting Devices (OLED) have attracted much attention recently

for their applications in futureFlat Panel Displays and lighting products. However

their fast degradation remained a major obstacle to theircommercialization. Here we present a brief summary of our studies on both extrinsic and intrinsic causes for the fastdegradation of OLEDs. In particular

we focus on the origin of the dark spots by "rebuilding" cathodes

which confirms thatthe growth of dark spots occurs primarily due to cathode delamination.In the meantime

we recapture the findings from the search for suitable OLED packaging materials

in particular polymer composites

which provide both heat dissipation and moisture resistance

in addition to electrical insulation.
