Sealing method for flat panel display device

Abstract

A method of sealing a flat panel display device by using laser and a charge-coupled device (CCD) camera. The sealing method includes applying a sealant around a light-emitting unit on a substrate and covering above the light-emitting unit with the encapsulating substrate; irradiating light onto a sealant area to harden the sealant for the first time (first hardening); monitoring a hardening state of the sealant; and further irradiating light onto a region of the sealant in a bad hardening state based on the monitoring result to harden the region of the sealant in the bad hardening state (second hardening). The sealing method may prevent a sealing flaw caused from insufficient laser irradiation dosage, and thus ensure a more stable sealed structure. This may improve quality of the flat-plan-display-device.
