Abstract:
1. An OLED device, comprising: a substrate; a first electrode formed over the substrate; one or more organic layers formed over the first electrode, at least one organic layer being a light-emitting layer; a bi-layer electrode comprising a first transparent conductive protective hermetic layer formed over the one or more organic layers, and a second transparent conductive non-hermetic layer formed over the first transparent conductive protective hermetic layer; and wherein the first transparent conductive protective hermetic layer includes metal oxide molecules, the second transparent conductive non-hermetic layer includes metal oxide molecules, the conductivity and the thickness of the first transparent conductive protective hermetic layer are both less than those of the second transparent conductive non-hermetic layer, and the metal oxide molecules of the first transparent conductive protective hermetic layer are arranged in a regular array and the metal oxide molecules of the second transparent conductive non-hermetic layer are randomly arranged.
