Abstract:
1. A color OLED display having at least three different colored microcavity pixels including a light-reflective structure and a semitransparent structure, comprising: a) 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 having a first spectrum portion that is substantially contained within a first color of the array, the second light-emitting material producing light having 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 having a third spectrum portion that is substantially contained within a third color that is different from the first and second colors; b) 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; and c) wherein the first, second, and third light-emitting materials are contained in separate red, green, and blue light-emitting layers, respectively, and wherein the red light-emitting layer includes a first host and a red light-emitting compound, the green light-emitting layer includes a second host and a green-light-emitting compound, and the blue light-emitting layer includes a third host and a blue-light-emitting compound.
