Abstract
A microcavity OLED device including a substrate; a metallic bottom-electrode layer disposed over the substrate; a metallic top-electrode layer spaced from the metallic bottom-electrode layer; and an organic EL medium structure having a defined thickness, and including a light-emitting layer comprising a host material and at least one dopant disposed between the top-electrode layer and the bottom-electrode layer; wherein one of the metallic electrode layers is light transmissive and the other one is essentially opaque and reflective; wherein the material for reflective metallic electrode layer includes Ag, Au, Al, or alloys thereof, and the material for the light transmissive metallic electrode layer includes Ag, Au, or alloys thereof. The at least one dopant is selected to generate one of red, green, or blue light in the light-emitting layer. The defined thickness of the EL medium structure is selected so that the microcavity OLED device is tuned for emission of one of red, green, or blue light through the light transmissive electrode layer.
