To do. Therefore, various displays can be performed by selecting and changing the injection location of the high-pressure water.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a display according to an embodiment of the present invention. In this display, a fluorescent film 2 is provided on the back surface of a substrate 1, the fluorescent film 2 is covered with a protective film 3 of an insulator to form a display body 4, and an injection device 5 installed behind the display body 4 is provided. The high pressure water W is sprayed from the nozzle 6 of the above to the protective film 3.

The substrate 1 of the display body 4 can be made of various materials such as a glass substrate and a plastic substrate, and its size and thickness are not particularly limited. Further, as in this embodiment, the display main body 4 is moved forward, that is,
When viewed from the side of the substrate 1, it is necessary to use the transparent substrate 1. On the contrary, when viewed from behind, that is, the opposite side of the substrate 1, the protective film 3 is opaque or semitransparent. It is also possible to do so.

The fluorescent film 2 on the back surface of the substrate 1 is formed by applying various phosphor powders dispersed in an organic binder such as cyanoethyl cellulose by screen printing or the like, or by forming the phosphor powder by vapor deposition or the like. The fluorescent substance is, for example, ZnS: SmF ₃ (red), ZnS: TbF.
₃ (green), ZnS: TmF ₃ (blue), CaS: En
(Red), CaS: Ce (green), SrS: Ce (blue), and other various phosphors used in conventional electroluminescent lamps can be used. The film thickness of the fluorescent film 2 is not particularly limited, but if it is too thin, pinholes and the like will occur, resulting in an incomplete film. Therefore, for example, when the film is formed by a method such as vapor deposition, the film thickness is set to 0.2 μ or more. It is desirable to do.
Further, the fluorescent film 2 may be formed of one kind of fluorescent material so that the whole has a single emission color. For example, as shown in FIG. It is also possible to alternately form the phosphor areas R for performing light emission, the phosphor areas G for emitting green light, and the phosphor areas R for emitting blue light in a stripe pattern so as to give a color change. Furthermore, the fluorescent film 2 may not be formed on the entire back surface of the substrate 1, but the fluorescent film 2 may be formed in an appropriate pattern shape such as letters, symbols, or patterns.

The protective film 3 for covering the fluorescent film 2 is formed by applying an insulating powder dispersed in an organic binder such as cyanoethyl cellulose by means such as screen printing, or by depositing the insulating material by means such as vapor deposition. And as an insulator,
SiO ₂ , Al ₂ O ₃ , Ta ₂ O ₅ , Si ₃ N ₄ and various other inorganic substances can be used. This protective film 3
Is essential to be made of an insulator, and if made of a conductor, the impact energy of high-pressure water leaks, which makes it difficult to excite the phosphor to emit light. The thickness of the protective film 3 is
In consideration of transmission of impact energy, it is preferable that the thickness is as thin as possible, but if it is too thin, it will be destroyed by the impact of high-pressure water, and it will not be possible to exert a satisfactory protection function. Specifically, since high-pressure water capable of giving energy of about 3 eV required for light emission of the phosphor is used, the thickness of the protective film 3 is set to 0.2 μm or more so as to withstand the impact of this high-pressure water. Is appropriate.

On the other hand, the jetting device 5 is provided with a nozzle 6 which can be swung back and forth and right and left. By controlling the angle of the nozzle 6 with a controller (not shown), the high pressure water W is supplied from the tip of the nozzle 6 to the rear surface of the display body 4. It is configured so that it can be ejected in a spot-like manner to a desired location of This high-pressure water needs to be pressurized at least to a pressure at which the energy required for light emission of the phosphor of the phosphor film 2 can be applied as impact energy, and preferably 3.0 eV or more energy is added to the phosphor. High pressure water pressurized to the pressure obtained is used. This is because the phosphor emitting blue light has the largest emission energy of about 3.0 eV. Therefore, if high-pressure water capable of imparting more energy is used, the emission color of the phosphor of the phosphor film 2 will change. This is because all things can be excited and emit light. Needless to say, the high-pressure water W having different pressures may be appropriately used depending on the type of phosphor, and the number of nozzles 6 may be two or more.

In the display configured as described above, when high-pressure water is jetted from the nozzle 6 of the jetting device 5 to the protective film 3 on the back surface of the display body 4, the impact energy is added to the fluorescent film 2 through the protective film 3, and the high-pressure water is discharged. The phosphor at the injection point is excited to emit light. Then, when the high-pressure water jetting location is moved while controlling the angle of the nozzle 6 by the controller, the light-emitting location is moved and various types of light-emitting display can be performed, which can be visually recognized from the front through the substrate 1. it can. Therefore, this display can be effectively used in an underground shopping center, a plaza, a park, an entertainment venue, or the like for an illumination or the like that attracts public attention.

FIG. 3 is an explanatory view showing such an example of use, in which the display main bodies 4 and 4 are arranged above the fountain 7 with a fountain device in a park or a plaza, and high-pressure water is displayed from the fountain device 8. The protective film 3 on the back surface of the main body 4 is sprayed to cause the fluorescent film 2 in the sprayed portion to emit light, thereby performing a fantastic illumination. In addition, each tile on the tiled wall surface is used as a substrate 1, a fluorescent film and a transparent protective film are sequentially provided on the surface, and the entire tiled wall surface serves as a display body. , Can be implemented in various ways.

The present invention has been described above with reference to the embodiment in which the fluorescent film 2 and the protective film 3 are formed on one side of the substrate 1, but the present invention forms the fluorescent film 2 and the protective film 3 on both sides of the substrate 1 from both sides. The high-pressure water may be jetted, and particularly when the phosphor films 2 on both sides are formed of phosphors having different emission colors, there is an advantage that various emission colors can be obtained by combining the emission colors of both. In this case, it goes without saying that the substrate 1, the fluorescent film 2 and the protective film 3 all need to be transparent or nearly transparent.

[Effect of device]

As is clear from the above description, according to the display of the present invention, various light emission displays can be performed by jetting high-pressure water to the display main body and selecting and changing the jetting location.
