发明名称 METHOD OF FABRICATING LIGHT EMITTING DEVICE
摘要 A method of fabricating a light emitting device is provided. A mother substrate including a plurality of light emitting units thereon is provided. A cover plate comprising a plurality of unit regions is provided. Each of the unit regions corresponds to one of the light emitting units. The cover plate further comprises a cutting line, a plurality of sealant regions and spacer disposing regions. A glass frit is coated on the cover plate in the sealant regions and the spacer disposing regions. A curing process is performed to solidify the glass frit in the sealant regions to form a sealant and solidify the glass frit in the spacer disposing regions to form a spacer structure. The cover plate is disposed on the mother substrate. A laser process is performed to the sealant but not the spacer structure so as to bond the cover plate and the mother substrate together.

主权项 1. A method of fabricating a light emitting device, comprising: providing a mother substrate including a plurality of light emitting units thereon; providing a cover plate comprising a plurality of unit regions, each of the unit regions corresponding to one of the light emitting units on the mother substrate, wherein the cover plate further comprises a cutting line around each of the unit regions, a plurality of sealant regions between the cutting line and each of the unit regions, and a plurality of spacer disposing regions between the cutting line and each of the sealant regions; coating a glass frit on the cover plate in the sealant regions and the spacer disposing regions; performing a curing process so as to solidify the glass frit in the sealant regions to form a sealant and solidify the glass frit in the spacer disposing regions to form a spacer structure; disposing the cover plate on the mother substrate, and a laser process is performed to the sealant so as to bond the cover plate and the mother substrate together, wherein the laser process is not performed to the spacer structure; and performing a cutting process along the cutting line, so as to form a plurality of light emitting devices.
