| 摘要 |
The present invention relates to an apparatus for sealing a frit using a laser which seals an organic light emitting display device from the outside, which is arranged in a frit, by irradiating a laser beam to the frit comprising a straight line part coated in a straight line and a corner part coated in a curve as being connected to the straight line part. The apparatus includes a condensing lens, an adjustment optical part and a laser beam movement unit. The condensing lens condenses the laser beam to the frit. The adjustment optical part is arranged on an upper side of the condensing lens, and adjusts a focus length of the laser beam condensed by the condensing lens in order for the laser beam irradiated to the frit to be defocused in case the laser beam is irradiated to the corner part. The laser beam movement unit moves the laser beam along a curvature radius smaller than a curvature radius of the corner part so that an area relatively far from the center of the laser beam is irradiated to the inside of the corner part and an area relatively close from the center of the laser beam is irradiated to the outside of the corner part, in case the laser beam is irradiated to the corner part. |
