Metallic Ag and Au nanostructures with different size on ITO coated glass substrates have been fabricated by using metal thin film dewetting technique for studying the light guide in a display system. The external quantum efficiency of the LED is influenced by high refracting rate materials. The increase of extraction efficiency is based on scattering light from the trapped photons. with Ag nanostructures in peripheral area of emitting region on the ITO coated glass substrates, the external quantum efficiency of devices increases by about 20 %. We have demonstrated that metal thin film dewetting technique can be applied to fabricate metallic nanostructures in backlight layer for LED or OLED systems.
