Abstract

1524831 Sealing gas discharge display panels PANEL TECHNOLOGY Inc 29 July 1975 [30 July 1974(4)] 31600/75 Heading C1M [Also in Division H1] The substrate plate 50 on which cathode electrode segments are printed and the anode plate 51 of a gas discharge display panel are sealed together in spaced apart relation by a sealing member 55 which extends around the periphery of the opposed substrates except for an opening 65 therein through which the panel is evacuated and filled with gas as necessary prior to the seal being completed by sealing the opening 65 with a fusible glass plug 66, Figs. 7 and 8 wherein the plug 66 overlies the spaced terminal ends 56, 57 of the sealing member 55 and is completely confined between the plates 50, 51 and is spaced inwardly of the edges thereof. The sealing member 55 is shaped from a cane of bubble-free fibre-optic type glass having a softening temperature of 450‹ C. which during assembly is temporarily held in position on one of the substrates by unfused dielectric. Hard glass spacer rods 58, 59, similarly tacked on to a substrate, define the desired discharge gap between the cathode and anode elements on the substrate. The fusible plug 66 is formed of glass having a fibre softening point below that of the sealing member 55. After the element 55 has been sealed in position with the help of externally applied heat and pressure, one or more of the panels are disposed in a chamber which is first evacuated and then filled at ambient room temperature to 120 torr with the filling gas of 99À5% neon and 0À5% argon, to which radioactive krypton may be added, the devices then being heated so that the glass plug 66 fuses to the sealing member 55 to seal the gas chamber. Also incorporated into the panel is a filamentary glass mercury giver 60 which is disposed opposite a window in the envelope. After sealing a laser beam is projected on to this giver 60 to crack the capsule and release mercury into the envelope. [GB1524831A]
