Abstract
In the present invention, the vacuum packaging of a field emission display (FED) is achieved in a high vacuum apparatus using a glass-to-glass bonding. The apparatus may eliminate the problems encountered in the conventional art in which a ventilation tube is used, so that vacuum degree of the interior of panels of the FED is affected (decreased) by the gases generated in sealing the ventilation tube. Furthermore, in the prior art, a part of the ventilation tube remains on the panel of the FED for thereby increasing the thickness of the panels, and the ventilating of gases is not effectively performed by the extension of the tube and a big size hole. The vacuum packaging apparatus of the FED and method therefor according to the present invention are capable of more effectively packaging FED by implementing a glass-to-glass bonding by ventilating gases from the interior of the panel of the FED in a manner of a high temperature ventilation in a high vacuum apparatus, contacting a glass substrate piece with a hole formed in the panel of the FED and applying a DC voltage thereto. Therefore, it is possible to easily implement a vacuum packaging of the FED and vacuum degree of the interior of the FED panel may be increased.
