摘要
Nowadays, organic light-emitting diodes (OLEDs) have potential to disrupt the conventional and mainstream solid state lights (SSLs) and flat panel displays (FPDs) due to their numerous superlative characteristics like sunlight style color-temperature tunability, energy-saving, environmental-friendly, physiologically- and psychologically-friendly, and a very high color rendering index (CRI), etc. However, the commercial viability of OLEDs would strongly depend on their extrinsic and intrinsic lifetime because OLED efficacy and lifetime greatly suffer from exposure to atmospheric oxidants (moisture and oxygen). The effect of oxidants can be minimized by the use of abundant emerging encapsulation techniques while the intrinsic lifetime can be improved by a balanced device structure and high glass transition temperature based materials, etc. © 2013 Woodhead Publishing Limited.
