When it comes to competing with liquid-crystal displays (LCDs) in the lucrative consumer electronics market, organic light-emitting-diode (OLED) displays have been hampered by limited lifetimes and higher production costs. While it is widely acknowledged that OLEDs offer better brightness, contrast, and color, they still suffer from degradation problems. The key challenge for OLED manufacturers is to develop hermetic packaging with adequate barrier films that protect the OLED materials from degrading when exposed to moisture and oxygen, particularly with polymer-based displays.
