  • Publication number: 20080211398
    Abstract: A flat panel OLED device including a transparent deformable substrate having first and second sides and defining a predetermined illumination region and a non-illumination region; a moisture-sensitive OLED disposed over the first side of the transparent substrate within the illumination region and means for applying electrical signals to the OLED which causes the OLED to produce light and heat; a protective layer disposed over the OLED; a flexible encapsulating foil disposed over the protective layer, but not attached thereto, and which dissipates the heat and sealingly connected to the substrate in the non-illumination region; and a rigid chassis structure operatively associated with the transparent deformable substrate for providing rigidity to the transparent deformable substrate.

  • Publication number: 20070207345
    Abstract: An OLED device comprises an anode, a light emitting layer, a first layer, a second layer contiguous to the first layer, and a cathode, in that order. The first layer includes a first complex comprising gallium or another group 13 metal and the second layer includes a second complex also comprising gallium and wherein the second complex has a more negative LUMO than the first complex. Such materials can provide an improvement in one or more of luminance, drive voltage, and stability.

  • Patent number: 7247394
    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: 7214554
    Abstract: A method for making an OLED device includes providing a substrate having one or more test regions and one or more device regions, moving the substrate into a least one deposition chamber for deposition of at least one organic layer, and depositing the at least one organic layer through a shadowmask selectively onto the at least one device region and at least one test region on the substrate. The method also includes measuring a property of the at least one organic layer in the at least one test region, and adjusting the deposition process in accordance with the measured property.
