  • Patent number: 11818937
    Abstract: An organic light emitting display is provided. The organic light emitting display includes a first base substrate; a plurality of organic light emitting diodes disposed on the first base substrate; an encapsulation layer disposed on the organic light emitting diodes; and a plurality of first color conversion filters disposed on the encapsulation layer. The encapsulation layer includes: a first sub-inorganic layer disposed on the organic light emitting diodes; a second sub-inorganic layer disposed on the first sub-inorganic layer and having a refractive index different from that of the first sub-inorganic layer; an organic layer disposed on the second sub-inorganic layer; and a third sub-inorganic layer disposed on the organic layer.
    Type: Grant

  • Patent number: 9159953
    Abstract: An organic light-emitting display device includes a first substrate; a display unit on the first substrate; an encapsulation layer covering the display unit; a second substrate on the first substrate, wherein the display unit is interposed therebetween; a sealant between the encapsulation layer and the second substrate and at the outside of the display unit, wherein the sealant bonds the encapsulation layer and the second substrate to seal them; and a getter on the encapsulation layer in a region between the sealant and the display unit.

  • Patent number: 8975621
    Abstract: An organic light emitting display device includes a first substrate including a pixel area and a non-pixel area; a pixel array formed on the pixel area of the first substrate; a protective layer formed over the pixel array, and having a trench that exposes at least a portion of the non-pixel area; a second substrate disposed above the first substrate; a sealing material disposed between the second substrate and the protective layer at the outside of the trench; and a getter disposed between the second substrate and the first substrate exposed by the trench. Moisture and/or oxygen penetrated through the sealing material and the protective layer, which are disposed at a side of the organic light emitting display device, are absorbed into the getter, thereby improving the lifespan of the organic light emitting display device.
