Abstract

1431877 Coating with glass; sealing display panels INTERNATIONAL BUSINESS MACHINES CORP 6 March 1975 [19 April 1974] 9311/75 Heading C1M [Also in Divisions C7 and H1] A component for a gas discharge display panel is made by covering metal electrodes on a glass substrate with a dielectric layer of borosilicate glass by evaporation by electron-beam of a molten pool of borosilicate glass in vacuo. The molten pool may have an area of 2 to 10 sq. cm., the substrate temperature may be 200- 300‹ C. and the chamber pressure 10<SP>-5</SP> to 10<SP>-7</SP> Torr; the glass may comprise (wt. per cent) SiO 2 82-89; B 2 O 3 8-15 and Na 2 O 1À7-2À4 and the deposition rate may be 40-80 Š/sec. The dielectric layer may be annealed at 500‹ C. for 30 minutes and then cooled at 80‹ C. or less per hour; it may be overcoated with MgO by vacuum evaporation. Oxygen may be added to the chamber atmosphere during evaporation of the glass; the coating thickness may be monitored. The glass panel may have parallel metal strips coated thereon or embedded therein; after coating as above two such panels are placed with the strips mutually orthogonal and the coated faces facing but spaced by a glass rod sealing member round the edge thereof, and the unit is sealed, containing a suitable atmosphere, e.g. Ne-Ar, to make the complete display device.
