Frit sealing system using laser and Frit sealing method using laser

摘要

PURPOSE: A frit sealing system which uses a laser is provided to process frit using a homogenized laser beam, thereby improving sealing quality of an organic display apparatus. CONSTITUTION: An internal space partitioned by a first substrate, a second substrate, and frit is sealed by projecting a laser beam to the frit(30) arranged between the first substrate and the second substrate. A homogenizer(120) is homogenized cross sectional energy distribution of the laser beam generated from a laser oscillation part. An inspection part inspects a state of the frit in which the laser beam is projected. The laser beam projected to the frit is changed when a difference between an inspected frit state and a pre-saved normal frit state exceeds a tolerance range.
