Encapsulation of a display element and method of forming the same
First Claim
Patent Images
1. A display element comprising:
- a glass substrate with an top surface on which a luminescent body is formed;
a glass cap with a bottom surface on which the rim is bonded to the rim of the top surface of the glass substrate to create an airtight space; and
a sealing layer formed on the bonding region between the glass substrate and the glass cap, wherein the sealing layer is frit.

Abstract
A display element has a luminescent body formed on a glass substrate, a glass cap with the rim bonded to the rim of the glass substrate, and a sealing layer of frit formed on the bonding region between the glass substrate and the glass cap. In encapsulating, the display element is placed between a pedestal an a pressing plate, and then a high-power laser beam is provided to penetrate the glass cap to focus on the sealing layer, resulting in sintering frit. Also, pressure is applied to the pedestal and the pressing plate.
