Title: Organic light emitting diode display with surface plasmon outcoupling

Abstract: An active matrix organic light emitting diode (OLED) display includes a substrate; a thin-film transistor (TFT) layer formed on the substrate; a layer defining a periodic grating structure; a first electrode layer formed over the grating structure and conforming to the grating structure; an OLED material layer formed over the first electrode layer and conforming to the grating structure; and a second electrode layer formed over the OLED material layer and conforming to the grating structure, wherein the first and/or second electrode layers are metallic layers, whereby the periodic grating structure induces surface plasmon cross coupling in the metallic electrode layer(s).
