  • Publication number: 20050249972
    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.

  • Patent number: 6961032
    Abstract: An OLED device, with each pixel including a plurality of laterally spaced first electrodes, each corresponding to a portion of the pixel and a common second electrode vertically spaced from the plurality of first electrodes; at least one light-emitting layer disposed between the first and second electrodes including a host and a dopant for emitting light in response to current; a hole-transporting layer disposed between the light-emitting layer and the first or second electrodes; and a transistor drive circuit for each pixel including separate transistors, each transistor associated with a different one of the first electrodes and when driven causes current to pass between its corresponding first electrode and the second electrode so that, if there is a short in the portion between an individual first electrode and the second electrode, the remaining portions will continue to produce light in the light-emitting layer, thereby reducing the effects of the short.

  • Publication number: 20050225233
    Abstract: A tuned OLED device includes a microcavity structure including a light-emitting layer for producing light, a semitransparent reflector, and a reflector layer disposed on opposite sides of the light-emitting layer, the microcavity structure enhancing on-axis light produced from the light-emitting layer in at least one particular wavelength to produce a desired on-axis viewed color while not substantially enhancing on-axis other wavelengths of such light; and a layer including a color change medium which is responsive to wavelengths of light shorter than the particular wavelength by absorbing such shorter wavelengths of light and emitting light corresponding in color to the particular wavelength, thereby improving the color of the light produced by the OLED device when viewed in an off-axis direction.
