Abstract: A family of dielectric glasses having properties such that, when heat is applied to seal the dielectric glasses, there is no crazing in a MgO overcoat. These dielectric glasses have such viscosity properties as not to craze a MgO overcoat in the range 455 to 505*C corresponding to log viscosity of 10.3 poises and yet fire into good dielectric films at about 600*C. The glass has substantially the following constituents:

Abstract: In plasma display panels requiring interstitial spacer elements within the display area to provide and maintain a uniform discharge gap, the spacers are positioned between lines which constitute the display. The lines adjacent the spacer elements experience a significant decrease in operating margin. This margin decrease is compensated for by either jogging the lines adjacent the spacers outwardly, by widening the lines in the affected areas or a combination of both. Various embodiments for providing this compensation are illustrated and described. KI9 77018

Abstract: METHOD OF MAKING GAS DISPLAY PANEL WITHOUT DISCRETE PANEL SPACERS A method is disclosed for the fabrication of a gaseous discharge display and/or memory device which provides a predetermined uniform gap between the inner walls of the gaseous discharge device without the use of spacer elements. Sealing about the panel periphery is provided by a devitrifiable seal glass, the viscosity of which is closely controlled as a function of time and temperature. The glass sealant, preferably in rod form, is extruded by mixing glass frit with a solvent-binder system to form a viscous slurry, extruding this slurry into rod form and thereafter sintering the rods in an oven under conditions whereby the sealant softens but does not reflow. The devitrifiable glass during the subsequent sealing process reflows and then crystallizes, and the viscous flow varies inversely as the crystallization. By careful control of the time, temperature, pressure and configuration of the devitrifiable sealing glass, the amount of flow of the sealing glass is controlled, and a predetermined and uniform chamber gap is provided. The subject invention represents an improvement in the assembly of gaseous discharge devices by eliminating the requirement for spacer elements. KI9-74-028

Abstract: A smaller glass plate is mounted at a given distance on a larger glass plate, which protrudes on all four sides beyond the smaller glass plate, by the application of solder glass along the edge of the smaller glass plate. Subsequently, the glass plates are heated to a relatively low temperature and the solder glass seals the two glass plates, thus forming a space for the gas discharge. After the glass plates have been sealed, the connecting strip (4) on the under side of the glass plate (1) is no longer accessible from the outside, but access to the two connecting strips (3, 4) is required.
