Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は蛍光表示管のグリッドの構造に圓する。[Detailed description of the invention] [Industrial application field] The present invention relates to the structure of a grid of a vacuum fluorescent display.
従来の蛍光表示管のグリッドの構造の一例を第2図に示
す。陽極基板5とカバーガラス6により構成された真空
気密容器からなる蛍光表示管10には、電子を放出する
複数の陰極1と、電子の衝突により発光表示される@極
基板5上に設けられた複数の陽極2および、陰極1と陽
極2の間に陽極全体を覆うように網目状のグリッド4が
設けられている。An example of the grid structure of a conventional fluorescent display tube is shown in FIG. A fluorescent display tube 10 consisting of a vacuum-tight container constituted by an anode substrate 5 and a cover glass 6 includes a plurality of cathodes 1 that emit electrons, and a cathode 1 provided on an electrode substrate 5 that emits light by collision of electrons. A plurality of anodes 2 and a mesh-like grid 4 are provided between the cathode 1 and the anode 2 so as to cover the entire anode.
上述した従来の蛍光表示管のグリッドは、陽極全体を覆
っているので、陽極面積が大きい場合にはそれに対応し
てグリッド面積も大きくなる。グリッド面積が大きいと
グリッド損失によるグリッドの変形が大きくなりグリッ
ドと陽極の間の距離が一定でなくなることから一様な表
示輝度を得ることができないばかりでなく、グリッドの
変形が特に大きい場合にはグリッドが陰極や陽極に接触
するという問題がある。Since the grid of the conventional fluorescent display tube described above covers the entire anode, when the anode area is large, the grid area also becomes correspondingly large. If the grid area is large, the deformation of the grid due to grid loss becomes large, and the distance between the grid and the anode becomes inconsistent, which not only makes it impossible to obtain uniform display brightness, but also when the deformation of the grid is particularly large. There is a problem with the grid touching the cathode or anode.
本発明の蛍光表示管は、陰極と複数の陽極の一部の間に
設けられた網目状のグリッドと、陽極と同一面上の残り
の陽極の周囲に設けられた導電層よりなるグリッドが、
同一表示管内に設けられている。The fluorescent display tube of the present invention has a mesh-like grid provided between a cathode and a portion of a plurality of anodes, and a grid made of a conductive layer provided around the remaining anodes on the same surface as the anode.
They are installed in the same display tube.
したがって、陽極面積が大きい場合でも網目状のグリッ
ドの面積がそれに対応して大きくなることはなく、シた
がって、グリッド損失によるグリッドの変形は大きくな

で、一様な表示輝度を確保できると共に、グリッドが陰
極や陽極iI:接)独するという問題点も解消される。Therefore, even if the anode area is large, the area of the mesh grid will not be correspondingly large, and therefore the deformation of the grid due to grid loss will not be large and the distance between the grid and the anode will not be large! Since it is kept constant, uniform display brightness can be ensured, and the problem that the grid is connected to the cathode or the anode is also solved.
次に、本発明の実施例について図面を参照して説明する
。Next, embodiments of the present invention will be described with reference to the drawings.
第1図は、本発明の蛍光表示冴の一実施例の断面図であ

はスタチック駆動部に設けている。FIG. 1 is a sectional view of one embodiment of the fluorescent display of the present invention. A grid 4a made of graphite with a thickness of 80 to 50 μm and a width of 1 to 2 islands is provided on the electrode substrate 5 around the anode 12a having the phosphor layer 718a, and the anode 2b having the other phosphor layer 3b. A mesh-like grid 4b made of 426 alloy and having a thickness of about 50 μm is provided between the electrode 1 and the cathode 1. In this case, a grid 4 made of conductive material
a is provided in the dynamic drive section, and a mesh-like grid 4b is provided.

。With such a configuration, the area of the mesh-like grid 4b is reduced, and the deformation of the grid 4b is also reduced. Further, the conductive material may be made of materials other than graphite, and the mesh grid may be made of materials other than 426 metal.

By reducing the area of the mesh-like grid, uniform display brightness can be obtained and the problem of the grid being deformed and coming into contact with the cathode or anode can be solved.
