Keywords:light extraction, viewing angle, TEOLED

We fabricated the nano-structure applicable for a highly efficient and color stable TEOLED by using thermal evaporation and organic vapor phase deposition, respectively. The nano-structure integrated TEOLEDs showed efficiency increase by 12% (thermal evaporation) and 32% (OVPD), respectively. The Δ(u’v’) from normal direction to 30o were 0.06 and 0.03, respectively.
