Abstract

A fluorescent luminous device includes a substrate, a plurality of anode electrodes disposed directly on the substrate, fluorescent layers disposed on the anode electrodes, a multiplicity of separators disposed on the fluorescent layers and the substrate, grid electrodes respectively disposed on the separators to form a matrix structure, and an electron-emitting source spaced apart from the fluorescent layers for exciting a fluorescent substance of the fluorescent layers. The fluorescent layer is of a stripe pattern or an array of fluorescent dots. In the latter case, at least a part of each of two neighboring separators is located on one fluorescent dot.

Description

field of invention [0001] The present invention relates to a fluorescent light-emitting tube and a manufacturing method thereof, wherein the fluorescent light-emitting tube has an anode and a grid in a matrix form, and the grid is formed on an insulating partition. Background of the invention [0002] Figures 6A to 6C A graphic fluorescent display tube is shown, the tube being of the prior art fluorescent light emitting tube type, wherein Figure 6A shows its floor plan; Figure 6B is along Figure 6A The sectional view made by the line "Y1-Y1"; Figure 6C yes Figure 6B A magnified view of a portion of . [0003] The prior art graphic fluorescent display tube includes an anode substrate 51 made of glass, filaments 61 respectively serving as cathodes, a fixing member 62 for applying tension to the filament 61, a support member 63 for supporting the filament 61, an insulating layer 64, Anode 71 , fluorescent layer 72 , spacer 73 made of insulating material, metal layer ...
