Abstract

PURPOSE:To acquire the good electrical continuity condition even when a low voltage is being applied by providing the connecting part of Al lead wire and Ag lead wire within a vacuum external case and covering it with a carbon film. CONSTITUTION:A lead wire 1 consisting of Al thin film is provided on a glass substrate 2, the lead wire 1 is not formed up to the terminal part and it is remained at the inside of vacuum external case surrounded by the face glass 3. Next, the Ag lead wire 4 is stacked on the Al lead wire 1 by the thick film printing method so that the lead wire 4 forms a part of internal lead wire from the terminal part of vacuum external case. A carbon film 5 formed by the thick film printing method is provided in order to cover the connecting part using graphite or carbon powder having excellent conductivity. Moreover, an over-coat glass 6 is formed in such a way as covering the entire part of the substrate 2 where these lead wires and carbon film 5 are provided.

Conventionally, the conductor wiring constituting the anode of a fluorescent display tube is formed by thick film printing of M or a thin film pattern of At on an insulating substrate such as glass constituting the vacuum envelope, and is not connected to the outside of the vacuum envelope. Only the lead-out terminal portion had a structure in which a thick Ag film was printed on a thin At film.

However, in such a conductor structure, the applied voltage is 5
In the case of high voltages higher than v, no particular problem occurs, but 5■
In the case of a low voltage below that, electrical continuity failure may occur. In other words, there is an oxide film on the At-Ag interface, and when a voltage of 5V or more is applied, it breaks and becomes conductive, but when it is less than 5V, this film acts as a barrier and prevents electrical conduction. .

FIG. 1 is a plan view showing an embodiment of the present invention, and FIG. 2 is a sectional view. In the figure, 1 is a lead wire made of an ALM film, which is formed on a glass substrate 2 through a normal process.
What should be noted here is that the At lead wire 1 is not formed all the way to the terminal portion, but remains in the middle of the lead wire, that is, inside the vacuum envelope quadrupled by the face glass 3. Next, 4 is an Ag lead wire formed by thick film printing, and this Ag lead wire 4 constitutes a part of the internal lead wire from the terminal part outside the vacuum envelope, and the tip is attached to the corresponding AtIJ-wire. It is formed so as to overlap and contact line 1. 5 is a carbon film provided to cover this contact portion. This carbon coating 5 is formed by thick film printing using, for example, Daraphite or its carbon powder having good local electroconductivity. Further, numeral 6 denotes an overcoat glass formed over the entire inner surface of the glass substrate 2 provided with these lead wires and the carbon coating 5, but this may be provided as necessary. Note that 7 is a frit glass for sealing.

Conventionally, as mentioned above, the oxide film 8 is formed at the interface between u and Ag, which prevents electrical conduction, but in the above structure, the formation of the oxide film 8 itself is caused by the elemental action of carbon. is suppressed. In addition, even when the oxide film 8 was formed between A7 and Ag, resulting in poor conductivity between the two, the conductivity between At-c and Ag-C was maintained extremely well in a vacuum atmosphere. In order to
Good electrical continuity is maintained between the two. In addition, in contrast to the conventional structure in which the A71J-do wire was covered with a thick film at the terminal part, the A1. −
Since the AH lead wire is connected, the lead wire that adheres to the sealing part by the frit glass 7 and the terminal part extending outside the vacuum envelope has the advantage that it can be made only of Ag, which has a high adhesive strength to the glass substrate. It also has Although the above embodiments have been explained using Ag, the situation is similar in the case of Au, and interface problems such as purple plague occur between Au and Al. The structure of the present application is also effective for this purpose.
