Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric decoration type 3D display which can be stereoscopically viewed without using glasses by using a lenticular plate, and is particularly durable against long-term use and allows easy exchange of patterns. The present invention relates to an illuminated 3D display.

[0002]

2. Description of the Related Art Conventionally, it is well known that there is a display capable of stereoscopic viewing without using glasses by using a lenticular plate.

As a form of this display, a small one is a badge attached to the chest, a postcard, or the like. Also,
The A4 and A3 sizes are used for over-the-counter advertisements and the like. Then, when the size further increases, there is a so-called illuminated type 3D display in which a light source for transmitted illumination such as a fluorescent lamp is attached behind.

FIG. 6 is an external perspective view showing an example of the most general constitution of a conventional electric decoration type 3D display of this type.

That is, as shown in FIG. 6, a color film (or printed matter) 2 on which a 3D image is combined is adhered to a lenticular plate 1. Here, during bonding,
The lenticular plate 1 and the color film 2 are aligned with each other. Then, at the time of display, the color film 2 is uniformly illuminated from behind by the transillumination light source 3 to form a bright, beautiful and three-dimensional display.

However, in the case of the display having such a configuration as shown in FIG. 6, if the screen size is 100 inches, the thickness of the lenticular plate 1 is 40 mm, and the weight thereof is 180 kg, which is very heavy. In this case, the weight of the display becomes too heavy and it is difficult to handle it manually.

Therefore, in order to reduce the weight and to handle it easily, recently, an electric decoration type 3D display having a structure as shown in FIG. 7 has been proposed.

That is, as shown in FIG. 7, the lenticular plate 1 and the color film 2 are separated and separated from each other, and a hollow portion (air layer) 4 is provided between the lenticular plate 1 and the color film 2. It is composed.

The lenticular plate 1 has a function of a lens and has a focal length. And color film 2
Since the color film 2 is held at the focused position, the color film 2 is integrated with the holding plate 5 made of a colorless and transparent resin plate (for example, an acrylic plate) with a colorless and transparent adhesive or pressure-sensitive adhesive.

When the display having the structure shown in FIG. 7 is used, there is almost no problem in short-term use (exhibition).

However, the following problems occur when used for a long period of time.

That is, the heat generated from the transillumination light source 3 causes a warp between the color film 2 and the holding plate 5, so that the central portion is locally bulged or dented. As a result, the central portion becomes blurred, which impairs the stereoscopic effect.

Further, since a large-sized display is expensive, it is required to be used for a long period of time, but the structure as described above cannot withstand it. That is, lenticular plate 1
In addition, its own weight causes distortion and the like, and it cannot withstand long-term use.

Further, when it is used for a long period of time, there is a demand for the replacement of the design, but with the above-mentioned configuration, the replacement of the design, that is, the color film 2 cannot be easily performed. . Also, the lenticular plate 1 cannot be easily aligned with the replacement of the color film 2.

[0015]

As described above, in the conventional illumination type 3D display, not only can it not be used for a long period of time, but also the exchange of the pattern and the position of the lenticular plate accompanying it. There was a problem that it was difficult to make the adjustment.

The present invention has been made to solve the above-mentioned problems, and can withstand long-term use, and
It is an object of the present invention to provide an extremely reliable electric decoration type 3D display capable of easily exchanging a pattern and aligning a lenticular plate with it.

[0017]

In order to achieve the above object, the present invention comprises a lenticular plate, a color film on which a 3D image is combined, a light source for transmitted illumination, and an outer frame which is a display body. In a 3D display that can be viewed stereoscopically without glasses, a color film is separately provided behind the lenticular plate via an air layer that is a hollow part, and the lenticular plate is covered by a plurality of hanging members. The color film is hung from above the frame and is attached and fixed to the outer frame so that it can be moved and rotated in the horizontal direction freely. Mounted and fixed in a pulled state, and the position of the color film itself is aligned with the focal plane of the lenticular plate. It is arranged so as to entirely uniformly illuminated from the side opposite to the lenticular plate side.

Here, in particular, the above-mentioned lenticular plate is hung from above with respect to the outer frame by a plurality of suspending members whose suspension length is adjustable, and each suspending member is slidable with respect to the outer frame. The lenticular plate is rotated in the horizontal direction and the hanging length between the hanging members is adjusted.

In the color film, the outer peripheral portion of the pattern portion of the color film itself is reinforced with a reinforcing material, and then eyelet fittings are attached. From the eyelet fittings, the hook-shaped fittings are attached inside the outer frame. A spring is attached between and to fix the color film to the outer frame.

[0020]

Therefore, in the electric decoration type 3D display of the present invention, the lenticular plate and the color film are separately provided through the hollow portion (air layer), so that the heat generated from the light source for transillumination illumination is used. In addition, the color film is not warped, and the color film is not locally swollen or dented, and the original three-dimensional effect can be maintained for a long period of time.

Further, the lenticular plate is hung from above with respect to the outer frame by a plurality of hanging members,
The lenticular plate is free from distortion or the like due to its own weight, and can be used for a long period of time.

Further, by disposing the lenticular plate and the color film as separate bodies, even if there is a demand for replacement of a picture pattern during the use for a long period of time, it is sufficient to simply replace the color film. , It is possible to easily exchange the design.

Further, the lenticular plate can be easily moved and rotated with respect to the outer frame so that the lenticular plate can be easily aligned with the replacement of the color film. .
