This invention provides a method for maintaining vacuum of a panel module and a structure of the panel module. A sealing material is suspended inside the panel module right above an exhaust opening of the panel module connecting with an exhaust tube. After exhausting the inside of the panel module, the sealing material is heated and molten so as to drop down to seal the exhaust tube. As such, the panel module becomes vacuum-tight. During a subsequent annealing process to heat the exhaust tube to its melting temperature, ambient air is prohibited from flowing into the panel module.

The present invention provides a field emission system and a method for improving its vacuum. The present invention employs aging surface-unsaturated carbon nanotubes in non-display areas of the field emission system as getter material to absorb residual gas within the system so as to improve its vacuum. The present method for improving vacuum of the field emission system can be integrated with the standard process of a field emission display device without additional fabricating steps, and thus facilitating the mass production of the field emission display device.
