[0013]

In the display apparatus according to the present invention having the above-mentioned structure, an ordinary fluorescent lamp is provided on the bottom surface, and an ultraviolet-emitting fluorescent lamp (hereinafter referred to as an ultraviolet fluorescent lamp) which is usually called a black light. The display sheet is mounted on the electroluminescent display device in which the above are alternately arranged so as to cover the opening. At this time, it goes without saying that the back surface of the exhibit sheet, that is, the white fluorescent pigment layer that emits colored light under ultraviolet rays is directed toward the light source.

When the display sheet according to the present invention is mounted on the display device, the display sheet may be mounted on the opening of the display device as it is, or on the back surface of the display sheet, for example, milky white. The acrylic plate or the white diffuser plate such as a polyester sheet is attached to the illumination display device in a superposed state.

The display device according to the present invention alternately emits a normal fluorescent lamp group and an ultraviolet fluorescent lamp group at a time interval.

When a normal fluorescent lamp group is emitting light,
The original motif of the transparent positive image is displayed. That is, the pattern, color, etc. carried by the transparent positive image like a color slide are naturally displayed. This is the same as in the conventional electroluminescent display device.

At this time, since the white fluorescent pigment layer formed on the back surface of the transparent positive image functions as a kind of light diffusing plate, the light which was indispensable when the display sheet was attached to the conventional electro-luminescent display device. The diffuser plate can be omitted.

Alternatively, if the light diffusing plate is further superposed on the display sheet, the degree of light diffusion is increased, so that the distance between the display sheet and the light source can be reduced, and as a result, the illumination display device can be made thin. can do.

The characteristic operation of the display device according to the present invention is as follows.
It occurs when the normal fluorescent lamp group is turned off and the ultraviolet fluorescent lamp group is turned on instead.

That is, when the group of ultraviolet fluorescent lamps is turned on, the white fluorescent pigment layer formed on the back surface of the transparent positive image is irradiated with ultraviolet rays and, for example, blue (blue), lemon yellow, orange yellow, green. Lights up in (green), pink (pink), cerise (cherry), orange, red (red), or red-orange.

As a result, the emission color of the white fluorescent pigment layer is added to the color of the display sheet, and it is as if the entire surface of the display sheet is filtered by the emission color.

Therefore, the design of the display sheet does not change, but the color changes, so that a different impression is displayed.
For example, if the white fluorescent pigment layer emits orange light, the daytime landscape becomes like an evening landscape.

By alternately performing the lighting of the normal fluorescent lamp group and that of the ultraviolet fluorescent lamp group in this manner, two kinds of displays appear alternately on the display surface of the same electroluminescent display device.

The display device according to the second aspect of the invention is
The point that the white fluorescent pigment layer that emits colored light under ultraviolet rays is not formed directly on the back surface of the transparent positive image but through a transparent sheet polymerized to the transparent positive image, is different from the one described in claim 1. Therefore, further detailed description will be omitted.

Also, in the display device according to the second aspect of the invention, the white fluorescent pigment layer that emits colored light under ultraviolet rays is not formed directly on the back surface of the transparent positive image, but on the white diffuser plate polymerized on the transparent positive image. Since only the points that are different are different from those described in claim 1, further detailed description will be omitted.

The display device according to the inventions of claims 4 to 6 is particularly suitable for the case of alternately displaying a daytime landscape and a nightscape.

That is, for example, if the display sheet for displaying a daytime landscape is irradiated with ultraviolet rays from the back side without any processing, the ultraviolet rays are invisible rays, and thus become dark like a night scene without a moon.

Therefore, in the invention described in claim 4,
When displaying a night scene with white diffusive paint that does not emit light under ultraviolet light, on the transparent positive part that you want to darken, on the part you want to emphasize the white fluorescent pigment that emits white light under ultraviolet light in the night scene,
In addition, a white fluorescent pigment that emits colored light under ultraviolet light is applied on the back surface side to selected portions of the transparent positive image in consideration of the original color of the transparent positive image.

Then, by illuminating this display sheet from the back side with an ordinary fluorescent lamp group, the above various white diffusing paints and white fluorescent pigments all have the same function as a white light diffusing material under ordinary visible light. Therefore, as in the case where the white fluorescent pigment that emits color under the ultraviolet light is uniformly formed, the daytime scenery appears according to the original motif carried by the transparent positive image.

However, when this display sheet was irradiated with a group of ultraviolet fluorescent lamps, the part coated with the white diffusive paint that did not emit light under ultraviolet light became dark, and a white fluorescent pigment that emitted white under ultraviolet light was applied. The part floats up like in the daytime, and the part coated with white fluorescent pigment that emits colored light under ultraviolet rays is added with the background color of the transparent positive image and the emission color under ultraviolet light, and The color changes to a color different from the emission color. By utilizing this color change, for example, a night view is displayed.

In the display sheet according to the present invention, the white diffusing paint that does not emit light under ultraviolet light, the white fluorescent pigment that emits light under ultraviolet light, and the like are not directly applied to the transparent positive image but through the transparent sheet. Only the point that they are applied in an interstitial manner differs from the invention according to claim 4,
Since the operation is almost the same, further detailed description will be omitted.

Also, in the display sheet according to the invention as set forth in claim 6, the white diffusing paint which does not emit light under ultraviolet rays, the white fluorescent pigment which emits light under ultraviolet rays, etc. are not directly attached to the transparent positive image but the white diffuser plate. The only difference from the invention according to claim 4 is that it is applied in an intervening manner, and the operation is almost the same, so a further detailed description will be omitted.
