A SEALING METHOD FOR FLAT PANEL DISPLAY DEVICE

摘要

Disclosed is a method for sealing a flat panel display device by using laser and a charge-coupled device (CCD) camera. The sealing method includes the steps of radiating light onto a sealant area on a substrate to harden the sealant for the first time (first hardening); monitoring a hardening state of the sealant; and further radiating 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 ensuring a more stable sealed structure and improving quality of the flat panel display device.
