Method and apparatus for sealing pumping gas-filling and seal-off according to the in-line methodology for manufacturing plate-type display element

摘要

The present invention is a flat panel display device, especially a plasma display panel face of the process for making (PDP) (sealing), the exhaust (pumping), gas injection (gas-filling) and sealing (seal-off) in the same vacuum chamber, in-the present invention relates to an apparatus and method for performing in-line manner.; After attaching to remove the front plate and a back plate constituting the flat panel display device in a high vacuum chamber, heating with a sealing material for the front plate and a back plate in a state in which injection of an inert gas such as argon (Ar) gas sealing, and separately also to for through the position adjusting means forming the getter is formed on the back plate holes enable the getter after placing the cap which contains the getter and at the same time the sealing of the cap, and encounter through gas injection holes formed in the rear plate and exhausting the inside of the flat panel display device, the face of a flat panel display to the interior of the device injecting a predetermined gas achieve the desired pressure, for a sealing cap for a separate position control means for the gas injected into the back plate hole after placing on the sealing member for sealing formed on said cap for sealing through a separate heating means or cyano Dick bonding method, after the sealing of the line system Exhaust, and relates to a gas injection and sealing method and the apparatus.
