Abstract
A color OLED display having at least three different colored microcavity pixels including a light-reflective structure and a semitransparent structure comprising an array of light-emitting microcavity pixels each having one or more common organic light-emitting layers, said light-emitting layer(s) having first, second, and third light-emitting materials that produce different light spectra. The first light-emitting material producing light has a first spectrum portion that is substantially contained within a first color of the array, the second light-emitting material producing light has a second spectrum portion that is substantially contained within a second color that is different from the first color, and the third light-emitting material producing light has a third spectrum portion that is substantially contained within a third color that is different from the first and second colors.
