Top-emitter OLED device structure and method

摘要

A top-emitting OLED device, comprising: one or more OLEDs formed on a substrate; a light-scattering layer formed over the one or more OLEDs; a transparent cover; one or more color filters formed on the transparent cover; a color-conversion material layer formed over the color filters, or formed over or integral with the light-scattering layer; wherein the substrate is aligned and affixed to the transparent cover so that the locations of the color filters and color conversion material correspond to the location of the OLEDs, and the color-conversion material layer, color filters, and the light-scattering layer are between the cover and substrate, and a low-index gap is formed between the light-scattering layer and the color filters, with no light-scattering layer being positioned between the color conversion material layer and the low-index gap.
