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.
