Laser beam irradiation apparatus for substrate sealing and method of manufacturing organic light emitting display device using the same

摘要

A laser beam irradiation apparatus irradiates a laser beam onto a sealing unit disposed between a first substrate and a second substrate so as to seal the first substrate and the second substrate. A center portion of the laser beam comprises a first beam profile having a beam intensity which increases toward a beam center portion, and a center of each of a plurality of peripheral portions of the laser beam is included in an area onto which the first beam profile is irradiated. The plurality of peripheral portions are symmetrically distributed around the first beam profile, and comprise a plurality of second beam profiles having the same beam intensities. The first beam profile and the plurality of second beam profiles are symmetrically distributed around a center point of the first beam profile and move in synchronization with one another.

1. A method of manufacturing an organic light emitting display device, the method comprising the steps of:
forming an organic light emitting unit on one of a first substrate and a second substrate; forming a sealing unit between the first substrate and the second substrate so as to surround the organic light emitting unit; aligning the first substrate and the second substrate; focusing a laser beam on the sealing unit, wherein a center portion of the laser beam comprises a first beam profile having a beam intensity which increases toward a beam center portion, and a peripheral portion of the laser beam comprises a plurality of second beam profiles, wherein a center of each of the plurality of second beam profiles is included in an area onto which the first beam profile is irradiated, and the plurality of second beam profiles are symmetrically distributed around the first beam profile and have the same beam intensities, wherein the first beam profile and the plurality of second beam profiles are symmetrically distributed around a center point of the first beam profile and move in synchronization with one another; and irradiating the laser beam along a sealing line of the sealing unit.
