Embodiment Construction

[0108] Below to Figure 1A-1D as well as figure 2 Based on this, the fluorescent display tube of the present invention will be described.

[0109] (Formation of anode substrate)

[0110] An aluminum film layer is arranged on the upper surface of an insulating substrate (110) made of soda-lime glass, and then a wiring layer is formed by photolithography, and the wiring layer includes: (i) gate wiring (121); (ii) ) electrically connecting the gate wiring (121) and the gate terminal A (127) of the gate (410); (iii) electrically connecting the gate for energizing the gate wiring (121) from the outside The gate terminal B (125) of the wire (421); (iv) the anode wire (122); (v) the anode wire (422) electrically connected to the anode wire (422) for energizing the anode wire (122) from the outside; Extreme (126).

[0111] Next, in order to cover the wiring layer, an insulating layer (130) is formed by using a paste mainly composed of low-melting glass and a pigment by a thick fi...

Abstract

To provide a dynamic drive fluorescent display tube easy for handling and having a plurality of cheeper grids. The dynamic drive fluorescent display tube has an assembly including a grid having an opening of the form of a mesh on a metal thin plate having a thickness of 0.1mm-0.15mm, a connecting member A B for fixing the grid to a vacuum sealed container, a connecting member for connecting the connecting member A and the grid to a grid wiring, and a lead for connecting the grid wiring and a positive pole wiring. A plurality of grids are formed by connecting each grids with grid wirings on a cathode substrate, and placing the grids and positive pole leads into different areas.

Description

technical field [0001] The invention relates to the improvement of grids used in fluorescent display tubes and a dynamically driven fluorescent display tube with multiple grids. Background technique [0002] A fluorescent display tube has a vacuum-tight container in which a high vacuum state is maintained. An anode conductor and a phosphor layer are formed on the upper surface of an insulating substrate made of a glass plate constituting a part of the vacuum airtight container to form an anode. Furthermore, a grid with grid-like openings is disposed above the phosphor layer, and the combination of the phosphor layer and the grid is used as a set of digits, and there are multiple digits in the same vacuum airtight container. . A filament is drawn above the grid. [0003] When the fluorescent display tube is in use, a filament current is supplied to the filament-shaped cathode from the outside through a wire, so that it emits thermal electrons. [0004] In the state of emi...
