Taking a fluorescent display tube, which is one type of display tube, as an example, the explanation will be given below.
As shown in the figure, glass cut into a planar shape or
An anode substrate 1 consisting of a conductive printed wiring, an insulating layer and a display segment laminated on the surface of an insulating substrate made of ceramic or the like, a grid 2 on a spacer 7,
The filament 3 and the filament 3 with electrode parts such as its support 4 are combined and mounted on a display, and a bulb 6 made by molding a translucent plate glass is hermetically sealed with a low-melting glass 5. It was attached to form a vacuum vessel and was used as a sealed display tube.
In this case, when processing the anode substrate 1, warping occurred in the longer diameter direction as shown in FIG. 2A for the reasons described below, which caused sealing holes. . That is, as described above, conductive printed wiring for supplying power to the display segments is formed on the surface of an insulating substrate 1 such as a glass plate or ceramic cut into a planar shape, and is baked and welded at a predetermined temperature. An insulating layer is formed using an insulating glass paste and welded at a predetermined temperature. At this time, a through-hole portion is provided to electrically connect the conductive printed wiring for supplying power to the display segment and the display segment.
A method is adopted in which a display segment is formed in this portion and electrical connection is made.

も余分な工数や歩留低下の要因となつていた。 In such cases, there may be a difference in the expansion coefficient between the insulating glass and the glass plate cut into a flat shape to insulate the conductive printed wiring for supplying power to the display segment and the display segment, or the insulating glass may be baked and welded. The substrate may warp due to the cooling rate and other factors after cooling. Therefore, when combined with a bulb, there is a gap between the short side of the bulb and the substrate (Figure 2B).
This was causing holes. In order to solve these problems, conventional methods have been to increase the amount of low melting point glass for sealing, or to clog the areas where sealing holes have occurred with low melting point glass paste for sealing.
Means such as resealing have been used. However, a drawback of the above solution is that printing a thick film of glass paste on a narrow portion of the flat sealing portion requires multiple printings, which tends to require a large amount of man-hours. On the other hand, when sealing holes are filled with glass paste,
Not only does it require a lot of man-hours for clogging, but since sealing is performed twice, the original display characteristics cannot be obtained, and in both cases, this causes extra man-hours and a decrease in yield.
本考案の目的は、気密封止を確実に達成できる
構造を有する表示管を提供することにある。 An object of the present invention is to provide a display tube having a structure that can reliably achieve hermetic sealing.

部的に帯状の凸部を設けたことを特徴とする。 This invention aims to prevent sealing holes by forming a band locally on the flat sealing part (flange part) on the shorter side of the bulb, which is affected by the warpage of the anode board, to compensate for the warping of the anode board. It is characterized by having a convex portion.

によつて扁平型の多桁螢光表示管が製造された。 This new type of bulb was manufactured by hot-forming ordinary plate glass (1.3 mm thick) cut to the specified size using a carbon mold. The carbon mold used for hot forming consists of a combination of three partial molds with different functions: an upper mold (male mold) that makes the valve concave, and a middle and outer mold that molds the flange part 6' of the valve. It consists of a lower mold (female mold) that molds the surface.
In order to compensate for the warpage of the anode substrate, a recess with a depth of 0.2 mm was provided on the short side of the mold for forming the flange portion. FIG. 4A shows a valve thus formed. Also, Figure 4
A' shows an enlarged view of the flat part of the flange, height 0.2 mm.
The convex portion 62 is shown. (However, the figure shows the state after applying low melting point glass and installing the exhaust pipe.) The new type of valve manufactured by the above method has a conductive tin oxide film formed on its inner surface and PbO-B 2 on the surrounding flange 6'. An O 3 -ZnO-based low melting glass 5 was deposited, and at the same time an exhaust pipe 8 was attached using the same low melting glass. Thereafter, flat multi-digit fluorescent display tubes were manufactured using a method similar to that used for manufacturing conventional display tubes.
