摘要： A laser irradiation device includes a laser generator for patterning and a laser generator for preheating. A laser induced thermal imaging (LITI) method, includes preparing an acceptor substrate, laminating a donor substrate on the acceptor substrate, and irradiating a laser beam onto a predetermined region of the donor substrate and carrying out transfer using a laser irradiation device having a laser generator for patterning and a laser generator for preheating. Advantageously, a laser beam having high intensity generated by the laser generator for patterning is used to prevent the transfer layer from being degraded, and a laser beam generated by the laser generator for preheating is simultaneously used for preheating so that an edge open failure does not occur and the transfer can be readily carried out even in a portion having a step of the acceptor substrate.

摘要： Provided are a laser irradiation apparatus and method of fabricating an organic light emitting display using the same. The laser irradiation apparatus includes a mask positioned below the laser generator, and the mask is patterned such that lengths of an upper portion and a lower portion of a mask pattern are patterned longer than a length of a middle portion of the mask pattern with respect to the scanning direction. The method of fabricating an organic light emitting display includes scanning a laser beam on a predetermined region of the donor substrate using the laser irradiation apparatus to form an organic layer pattern on the substrate. When the organic layer pattern is formed using a laser induced thermal imaging (LITI) method, the transfer may be carried out using a laser beam having low energy, laser beam efficiency may be enhanced, the organic layer may be less damaged, and the quality of the organic layer pattern to be transferred may also be enhanced.

摘要： 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.

The method of fabricating the donor substrate includes preparing a base substrate that includes at least one transfer region and at least one non-transfer region, forming a light-to-heat conversion layer on the base substrate and depositing a transfer layer selectively on the light-to-heat conversion layer and in the at least one transfer region of the base substrate using a shadow mask.
