Abstract
A color OLED display having at least three different colored microcavity pixels, each including a light reflective structure and a semi-transparent structure includes an array of light-emitting microcavity pixels each having one or more common organic light-emitting layers, said light-emitting layer(s) including first and second light-emitting materials, respectively, that produce different light spectra, the first light-emitting material producing light having a first spectrum portion that extends between first and second different colors of the array, and the second light-emitting material producing light having a second spectrum portion that is substantially contained within a third color that is different from the first and second colors, and each different colored pixel being tuned to produce light in one of the three different colors whereby the first, second, and third different colors are produced by the OLED display.
