Fluorescent luminous tube and method for producing same

A fluorescent display device comprising:

• a substrate;
• a plurality of anode electrodes disposed directly on the substrate;
• an array of fluorescent dots disposed on the anode electrodes;
• a plurality of separators disposed on the fluorescent dots and the substrate, wherein at least a part of each of two neighboring separators is located on one fluorescent dot;
• grid electrodes respectively disposed on the separators, wherein the grid electrodes and the anode electrodes are arranged to form a matrix structure;
• and
• an electron-emitting source spaced apart from the fluorescent dots for exciting a fluorescent substance of the fluorescent dots.

A method for producing an anode substrate for use in a fluorescent luminous tube, comprising the steps of:

• forming anode electrodes directly on a bare anode substrate;
• forming fluorescent layers of a stripe pattern or a dot array pattern on the anode electrodes;
• forming separators on the fluorescent layers and exposed portions of the bare substrate such that the separators are arranged across the anode electrodes;
• forming grid electrodes on the separators to form a semifinished substrate;
• and
• baking the semifinished substrate.
