- We have developed the highly efficient OLEDs using the embossed glass substrate and the low yellowing TiO 2/Epoxy nano composite layer. The nano composite can be applied to a scattering layer and a planarization layer on an embossed glass. The TiO 2/Epoxy nano composite was effective for increasing the light extraction efficiency of OLEDs, however the yellowing degraded the luminous efficacy seriously. The luminous efficacy of the OLED with the nano composite layer on the embossed glass was 21.0 lm/W at 1000 cd/m 2 and it increased by 36% compared to the conventional OLED. © 2011 IEEE.
