A SEALING METHOD FOR FLAT PANEL DISPLAY PANEL USING CO2 AND DIODE LASERS

摘要

A sealing method for a flat panel display panel is provided to minimize a crack by minimizing a thermal stress generated in a substrate and a flit. In a sealing method for a flat panel display panel, the ambient temperature of a substrates within a chamber is ascended and descended by a preheating(20). A sealing area of the substrates including a frit is locally heated by using the first laser light source in the pre-heating step is locally heated(40). A first substrate and a second substrate are sealed by using the second laser light source in the sealing step(50). The ambient temperature of the chamber is descended(70).
