Method of manufacturing a gas discharge lamp display panel and gas discharge display panel manufactured according to said method

Abstract From the Canadian patent

In gas discharge display panels of some dimension a fracture in the seal between the plateshaped elements of the panel is obtained in many cases upon evacuating the panel. Said fracture is a result of the fact that the plate-shaped elements for example, the glass face plate of the panel are not entirely flat, so that said elements contact the intermediately located spacing members in an insufficient number of places. This problem is solved by producing the vacuumtight seal between the plate-shaped elements while maintaining such a pressure on the surface of said element that they are brought in permanent contact with the spacing members. Furthermore, at least the glass face plate is …
