  • Patent number: 8778726
    Abstract: An organic light emitting display in which differential pressure is controlled to prevent Newton's rings from being generated and a method of fabricating the same are provided. The organic light emitting display includes a first substrate including a pixel region in which at least one organic light emitting diode (OLED) is formed and a non-pixel region, a second substrate attached to one region including the pixel region of the first substrate, and a frit provided between the non-pixel region of the first substrate and the second substrate. At least one of the first substrate and the second substrate is formed to be convex outward.
    Type: Grant

  • Patent number: 7846001
    Abstract: A method for manufacturing an organic light emitting display. Pixel portions are formed on a mother substrate. A test wiring for testing pixel portions is formed at a peripheral portion of the mother substrate. A sealing material is formed at one surface of a sealing substrate to enclose the pixel portions, the sealing substrate being sealed to be spaced apart from the mother substrate. A spacer is formed at a side region of the one surface of the sealing substrate on which the sealing material is formed. The mother substrate and the sealing substrate are adhered to each other by the sealing material to seal the pixel portions within an enclosure formed by the mother substrate, sealing surface, and sealing material. A part of the sealing substrate is scribed and removed to expose the test wiring, the part of sealing substrate being arranged over a portion of the test wiring.
