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 grid terminal B (125) of the wire (421); (iv) the anode wiring (122); (v) the anode of the anode wire (422) electrically connected to the anode wiring (122) from the outside terminal (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 film printing method....

Abstract

The invention provides a dynamically driven fluorescent display tube, which has multiple grids with simple operation and lower cost. The fluorescent display tube uses the following parts, which are processed from a thin metal plate with a thickness of 0.1 mm to 0.15 mm. The connecting parts A, B, the grid wire and the anode wire are fixed on the vacuum airtight container, wherein the grid wire connects the inner wire of the grid with the junction A, and the inner wire of the grid connects the grid to the grid. On the pole wiring; the fluorescent display tube is equipped with a plurality of grids in the manner that the grid wires and the anode wires are arranged in different regions.

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...
