Abstract

Ein Gasentladungspanel enthält normalerweise zwei zueinander parallele Patten (1, 2, 3, 4), die randseitig über ein Glaslot miteinander verbunden sind und eine Vielzahl von durch den Glaslotrahmen (16) geführten (Schicht-)Elektroden (8, 9, 11, 12, 15) tragen. Eine solche Zelle wird zunächst bei 450°C verlötet, dann vollständig abgekühlt und anschließend bei höchstens 320°C ausgeheizt. Erfindungsemäß wird nun vorgeschlagen, die Ausheizung in die Abkühlphase zu ver­ legen, das heißt, die Zelle beim Abküklen einige Zeit auf der Ausheiztemperatur zu halten. Eine solche Wärmebehandlung ist in mehrfacher Hinsicht günstig: Die Ausheiztemperatur, die bisher durch die Temperaturwechselbeanspruchung be­ grenzt war, kann um mindestens 50°C erhöht werden; der insgesamt für die Lötung und die Ausheizung benötigte Zei­ traum läßt sich mindestens halbieren; die Elektroden (8, 9, 11, 12, 15) können zwischen der Lötung und der Ausheizung nicht mehr mit der Umgebungsluft reagieren. Führt man auch noch die Lötung in einer Inertgas-Atmosphäre durch, so kommt man auch mit empfindlichen Elektroden zu repro­ duzierbaren Ergebnissen. A gas discharge panel usually contains two flaps parallel to each other (1, 2, 3, 4), the edge over a Glass solder are connected and a variety of through the glass solder frame (16) guided (layer) electrodes (8, 9, 11, 12, 15). Such a cell is initially at 450 ° C soldered, then completely cooled and then baked at a maximum of 320 ° C. According to the invention proposed to ver the heating in the cooling phase that is, the cell cools down for a while Keep baking temperature. Such a heat treatment is favorable in several ways: the baking temperature, the be so far by the thermal cycling was limited, can be increased by at least 50 ° C; the total time required for soldering and heating dream can be halved at least; the electrodes (8, 9, 11, 12, 15) can be between the soldering and the heating no longer react with the ambient air. One leads too the soldering in an inert gas atmosphere one comes to repro even with sensitive electrodes reasonable results.

Hauptanwendungsgebiet: Flachbildschirm, bei dem Elektronen in einem Plasma erzeugt und - nachbeschleunigt auf einige kV - auf einen Phosphor gelenkt werden. Main application: flat screen, where Electrons generated in a plasma and - accelerated to a few kV - be directed to a phosphor.
