ABSTRACT:
A color organic light-emitting display device having an array of pixels divided into at least two different color pixel sets each color pixel set emitting a different predetermined color light over a common substrate, wherein each pixel in the array includes a metallic bottom-electrode layer disposed over the substrate and a metallic electrode layer spaced from the metallic bottom-electrode layer; wherein the material for reflective metallic electrode layer includes Ag, Au, Al, or alloys thereof, the material for the semitransparent metallic electrode layer includes Ag, Au, or alloys thereof; and wherein the thickness of the semitransparent metallic electrode layer, the combined thickness of the organic layers and the transparent conductive phase-layer, and the placement of the light-emitting layer are selected so that each pixel in the display forms a tuned microcavity OLED device having an emission output efficiency above that of a comparable OLED device without the microcavity.
