ABSTRACT:
A method of constructing a gas discharge display device in such a manner that contaminants found within the completed display are significantly reduced. The process for assembly of the display incorporates the utilization of a spacer member having a higher melting temperature than the display's perimeter seal and is designed to hold the plates apart without letting certain portions of the sealing material contact the opposing substrate. The use of the spacer member of high temperature material permits a higher temperature to be achieved in the vacuum furnace for evacuating the contaminants produced by out-gassing of impurities in the dielectric and conductive materials as well as the glass substrates and the sealing material. The sealing time for the display after evacuation is shortened to prevent or greatly reduce the possible entrapment of impurities in the display during the higher temperature final sealing step.
