Abstract:
1. A method for maintaining vacuum-tight inside a panel module, comprising: providing said panel module, said panel module at least including a first substrate, a second substrate and a side frame, said side frame disposed between said first substrate and said second substrate, and said second substrate having an exhaust opening; suspending a sealing material within said panel module such that said exhaust opening is formed right under said sealing material; connecting an exhaust tube to said exhaust opening of said second substrate; exhausting inside of said panel module via said exhaust tube so that the inside of said panel module attains a predetermined vacuum; heating said sealing material such that said sealing material is molten and dropped down to seal said exhaust tube, thereby the inside of said panel module becomes sealing-tight; and burning out said exhaust tube.
