  • Patent number: 9210764
    Abstract: An organic light emitting diode device includes a first electrode, a light emitting member on the first electrode, a second electrode on the light emitting member, which second electrode includes a first material, a protective member on the second electrode, which the protective member includes a second material having a larger absolute value of a standard oxidation potential than that of the first material, and a thin film encapsulating layer on the protective member.
    Type: Grant
    Filed: February 20, 2013
    Date of Patent: December 8, 2015
    Assignee: SAMSUNG DISPLAY CO., LTD.
    Inventors: Young-Sahn Lee, Young-Mi Cho, Kyung-Chan Chae
  • Patent number: 8895973
    Abstract: An organic light emitting diode display according to an exemplary embodiment includes a substrate, a pixel electrode on the substrate, an organic emission layer on the pixel electrode, a common electrode on the organic emission layer, a cover layer on the common electrode, an oxidation reducing layer on the cover layer, and a thin film encapsulation layer covering the oxidation reducing layer, the oxidation reducing layer being configured to reduce oxidation of the common electrode, the oxidation reducing layer being separated from the common electrode. The oxidation reducing layer may include at least one of a dummy common electrode, an ultraviolet ray (UV) blocking layer, and a buffer layer.

  • Patent number: 8759822
    Abstract: An organic light-emitting display apparatus including a substrate; an organic light-emitting device formed on the substrate; a thin film encapsulation layer that is formed on the organic light-emitting device and covers the organic light-emitting device; and a barrier layer disposed between the organic light-emitting device and the thin film encapsulation layer, in which the barrier layer includes a first barrier layer formed on the organic light-emitting device and including an alkali metal-containing compound; and a second barrier layer disposed between the first barrier layer and the thin film encapsulation layer and including an amorphous inorganic oxide.
