  • Publication number: 20100117093
    Abstract: In a laser irradiation device, a patterning method and a method of fabricating an Organic Light Emitting Display (OLED) using the same. The laser irradiation device includes a light source, a mask, a projection lens, and a Fresnel lens formed at a predetermined portion of the mask to change an optical path. When an organic layer pattern is formed using the laser irradiation device, laser radiation is irradiated onto a region of an organic layer, which is to be cut, and the laser radiation is appropriately irradiated onto a region of the organic layer, which is to be separated from a donor substrate. The laser radiation irradiated onto an edge of the organic layer pattern has a laser energy density greater than that of the laser radiation irradiated onto other portions of the organic layer pattern. As a result, it is possible to form a uniform organic layer pattern and reduce damage of the organic layer.

  • Patent number: 7687153
    Abstract: A donor substrate for laser transfer comprises: a base film; a light-to-heat conversion layer formed on the base film; and a transfer layer formed of an organic material on the light-to-heat conversion layer. The transfer layer contains a thermosetting electroluminescent material, and an organic electroluminescence display device is manufactured using the same. Thus, R, G and B emission layers are simply formed with a fine pattern by a thermal curing process after laser transfer. As a result, the emission layers are not damaged, and the manufacturing cost of a full-color organic electroluminescence display device is reduced due to employment of a simplified mask process. The donor substrate is advantageous to use in the manufacture of a large-sized organic electroluminescence display device.

  • Patent number: 7674749
    Abstract: A donor substrate for use in an organic light emitting display comprises a base substrate and a transfer layer disposed on the base substrate. A selective heat generation structure is interposed between the base substrate and the transfer layer. The selective heat generation structure has a heat generation region from which heat is generated by light-to-heat conversion and a heat non-generation region contacting the heat generation region. By employing the donor substrate, it is possible to form minute transfer layer patterns with high accuracy without the need to accurately control the width of a laser beam. A fabrication method of an organic light emitting display comprises disposing the donor substrate on an acceptor substrate, irradiating a laser beam onto the donor substrate, and forming a transfer layer pattern on a pixel electrode of the acceptor substrate.

  • Publication number: 20100045953
    Abstract: A laser irradiation device and a method of manufacturing an organic light emitting diode display device using the same. The laser radiation device prevents the scattering of the laser light into portions of the donor substrate that correspond to non-transmissive regions of a mask pattern. To reduce the scattering, the mask pattern is designed so that 1) non-transmissive regions of a surface of the mask pattern that faces the laser source have a reflective layer, 2) the surface of the mask pattern that faces the laser source is oriented to have a certain angle with respect to the laser beam axis, and 3) a surface of the mask pattern that faces the donor substrate has an anti-reflective layer. Each of these design aspects of the mask pattern prevents laser light from being scattered and prevents irradiating portions of the donor substrate that corresponds to a non-transmissive region of the mask pattern.
