  • Patent number: 12156460
    Abstract: An apparatus and method for manufacturing an organic light emitting diode (OLED) for lighting are disclosed. The manufacturing apparatus includes a plurality of rolling members configured to move, in a transverse direction, a band-shaped base having holes formed at predetermined intervals at both width-direction ends thereof, and arranged at predetermined intervals along a movement direction of the base, and a deposition unit configured to discharge a vaporization material from a deposition source and sequentially depositing the discharged vaporization material on one surface of the base, along with the movement of the base. A plurality of protrusion members are formed on one surface of each of the rolling members, to move the base by being inserted in and released from the holes at both ends of the base along with rotation of the tolling members.

    Abstract: Provided are a light-emitting element for lighting that is manufactured while being supplied in a roll form, including: a substrate that is wound/unwound on a roll, on which a deposition material is to be deposited with a pattern; gap maintaining protrusions that protrude at a plurality of positions on one surface of the substrate, and are configured to protect the deposition material while contacting the other surface of the substrate when the substrate is wound and unwound on the roll; an insulating layer that is disposed on the one surface of the substrate and is formed by stacking an insulating material; and at least one deposition layer that is formed by depositing at least one deposition material on the one surface of the insulating layer, in which the gap maintaining protrusions have a protrusion height greater than a height of the deposition layer, and a method for manufacturing the same.
