  • Patent number: 7812527
    Abstract: An organic electro-luminescent display device includes barriers in a non-display area to protect a display area from water and oxygen. Barriers may include a permeation prevention barrier, a voltage contact portion, and a blocking layer. A permeation prevention barrier includes contact portions where a barrier layer having a lower permeability than a passivation layer penetrates through the passivation layer. A voltage contact portion penetrates the passivation layer so that a signal supply line contacts a conductive material. A blocking layer covers a wall, a planarization layer, and an inorganic insulation layer, and has a lower permeability than the planarization layer, the wall, and the inorganic insulation layer. The permeation prevention barrier, the voltage contact portion, and the blocking layer may be used in various combinations.

  • Publication number: 20090261341
    Abstract: An organic light emitting display includes a pixel part adapted to generate a light and a metal oxide layer. The metal oxide layer is formed by oxidation of a metal layer combined with oxygen of gas or humidity in an inner space of the organic light emitting display. Accordingly, gas or humidity in the organic light emitting display is removed by the oxidation of the metal oxide layer to thereby inhibit deterioration in a light emitting function of the pixel part.

  • Publication number: 20090258134
    Abstract: In a method for controlling thin-film forming velocity, a method for manufacturing a thin film and a system for manufacturing the thin film, the method for controlling the thin-film forming velocity includes measuring the thin-film forming velocity at a target substrate by sensing a depositing source gas generated from a depositing source part. Then, a distance between the depositing source part and the target substrate is controlled so that the thin-film forming velocity substantially equals a predetermined thin-film forming velocity. Accordingly, the thin-film forming velocity is controlled by changing the distance between the depositing source part and the target substrate, so that time spent in controlling the thin-film forming velocity may be decreased.
