Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problems: a conventional display device for showing such a landscape as changing from a daytime view to a night view is complicated in its manufacturing process, or incapable of changing the view into a photograph-like realistic night view, or requires special printing or lighting. <P>SOLUTION: Daytime and nighttime landscape pictures photographed at the same point and at the same angle are printed on both-sides of one translucent sheet (7) in such a manner that the patterns of the landscape exactly overlap with each other when seen through, and the sheet is set in front of a device (8) provided with an internal light source (9). When the surrounding is bright and the in-device light source (9) is turned off, the daytime view on the front face is seen and, when the surrounding is dark and the in-device light source (9) is turned on, the night view on the rear face is visualized through. Thus, with a very simple configuration, a display device showing a landscape photograph changing from a daytime view to a night view and the like can be inexpensively manufactured. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention relates to a display device capable of changing the display of images of the same shape with different colors with a simple structure, such as changing a daytime landscape photo to a nighttime landscape photo.

Traditionally, a display device that changes a daytime landscape photo to a nighttime landscape photo using a computer, etc., or a blackout printed on a landscape photo with a night view printed with fluorescent ink or luminescent ink Light emitted from light or blue light, or one that displays a different pattern by using a motor to wind up the sheet, or light that enters from the side of a transparent resin plate that has been scratched to match the pattern in the photo There were things that shined scratches and produced a night view.
JP-A-9-43533

However, if a computer is used, it becomes a very expensive device, and printing of fluorescent ink and luminescent ink is impossible with a general-purpose printer, and it is integrated with a transparent resin plate wound up with a motor etc. It was not easy to replace only the seat.

Transparent or translucent sheet Each of the front and back sheets or multiple sheets, for example, pictures of scenes taken at the same spot and at the same angle, scenes of different seasons, or equivalent pictures and CG, etc. The light source is placed in front of, behind, or both of the whole or part of the display so that the symbols overlap in the same manner when watermarked.

The present invention does not require expensive parts such as a computer, and does not depend on the type of light source, so that it can be manufactured at low cost.

When printing the sheet used in the present invention, it is possible to use a general-purpose printer or the like without using fluorescent ink or light-emitting ink.

The present invention does not require a driving unit such as a motor integrated with the sheet, and can be manufactured so that the sheet can be easily replaced.

The present invention can use day and night scenery photographs that are actually taken as they are, and can change the photographs very realistically as compared with a display device that does not use expensive things such as a conventional computer. At the same time, in this case, only a photograph needs to be prepared for producing the sheet.

Any material can be used as long as it does not block light, such as paper, plastic or glass, and no special printing method is required for printing.

In the present invention, the basic structure is only a sheet and a light source, and the type of the sheet and the light source need not be specific, and it has a wide degree of freedom such as shape, size, weight, and thickness when commercialized. You can make anything from a small size to a large size on a building wall.

The basic best mode is to install a light source (Fig. 1-3, Fig. 2-6, Fig. 3-9) at the rear of the inside and open the front (left side of Fig. 1, Fig. 2, Fig. 3) ( 1-2, FIG. 2-5, and FIG. 3-8) and a sheet (FIGS. 1-1, 2-4, and 3-7) installed in the opening portion thereof.

The principle of image change can be explained as follows using day and night landscape photographs printed on the front and back of a single sheet. As shown in FIG. 4, when the day scene (10) and the night scene (11) taken through the same angle are watermarked on the front and back of the translucent sheet, the patterns overlap in the same way. Print on. However, when printing on the front and back of one sheet as in this example, the night scenery (11) must be reversed right and left. When the light source in the device is turned off in a bright environment, the device can see only the daytime scenery (14) on the front side, as shown in FIG. The night landscape printed on the back is naturally dark and invisible. On the contrary, when the surroundings are dark, when the light (15) of the light source inside the apparatus is applied to the translucent sheet (16) on which the photograph is printed from the rear as shown in FIG. Will be visible through. However, the front side design is not completely invisible at that time, and strictly speaking, it will be somewhat visible on the night landscape. It is necessary to print the photo so that it overlaps the same when the design is watermarked.

As shown in FIG. 7, if the sheet (18) can be easily exchanged by opening and closing the transparent plate (19) provided on the front surface, the sheet can be exchanged to meet various needs. It can be easily done without relying on the hardware side.

Photos of scenes with different times and seasons or equivalent pictures and CGs printed on the sheet indicate scenes with different seasons such as day and night, morning and evening, green leaves and autumn leaves, snowy mountains and summer mountains, etc. However, changes can be enjoyed, for example, in black-and-white and color photographs, or in pictures with partial color changes.
However, when printing on multiple sheets, the front sheet, when printing on one front and back, if the image on the front side of the sheet is darker or darker than the back sheet or the back side, it is difficult to transmit light It should be avoided if not intentional.

In addition to printing and painting, the display of images on the sheet can produce the same effect even if a thin colored sheet such as a cutting sheet is applied in layers.

The sheet may be a plate like a glass plate or a resin plate, for example.

The sheet is basically a milky white translucent sheet that is easy to reproduce all colors, but the entire surface or part of it is made translucent with color, or it is made transparent separately from the presence or absence of color, giving a different effect It is also possible.

As shown in FIG. 8, the back side design (21) with characters or the like not included in the front side design (20) is used. When light (22) is applied, characters and the like that are not in the design of the table can be raised (24).
On the other hand, if you change the color of the back of the part that overlaps with the characters etc. that only entered the front landscape, you can change the color of the letters when light is applied from the back, or make the same part of the back black It is also possible to erase characters and the like.

These things are not limited to letters, and even if you use illustrations such as angels, dragons, and monsters, you can produce different effects.
In addition, if this is applied, it is possible to create a display device in which only the scenery changes from day to night without changing the person. For example, a person is also taken at the time of shooting at noon, and only the person part of the photograph taken at noon on the back night view is synthesized at the same position. Then, even when the scenery other than the person changes to a night view, only the person part does not change and looks bright. The same effect can be achieved by removing the white color in the same shape. Further, a person may be synthesized from another photograph without taking a picture with the scenery in the daytime.

The illumination inside the apparatus can be colored illumination instead of white, or illumination of multiple colors can be provided. For example, after installing red and white light sources and lighting red light first to produce a sunset, only white light can be turned on for a night view.

Basically, the light from the front may be ambient light such as room light or sunlight, but if a sufficient amount of light cannot be expected, a light source (25) can be provided in front of the device as shown in FIG. Can be solved.

The light source inside the device may be anything such as a fluorescent lamp, LED, cathode tube, EL plate, natural light, etc. If combined with a light guide plate, a very thin device can be made.

As shown in FIG. 11, the inner box (29) is provided in the outer box (28), the front of each box is opened, and a transparent smoke plate (26) is provided on the opened surface of the outer box (28). On the open side of the inner box, a sheet (30) printed with symbols on both sides is installed.

Two types of light sources are prepared, one type of light source (31) is installed as a backlight in the inner box, and the other type of light source (27) illuminates the design sheet (30) from the front and visually recognizes the design. It is installed in the outer box (28) as a front light at a position where it does not get in the way.

When visually recognizing the design on the front of the seat, as shown in FIG. 12, by turning off the back light in the inner box and turning on the front light in the outer box, the light (32) of the front light hits the front of the seat, Only the reflected light (33) passes through the smoke plate, so that only the front surface of the sheet is visible.

On the other hand, when visually recognizing the pattern on the back side, as shown in FIG. 13, by turning off the front light in the outer box and turning on the backlight in the inner box, the backlight light (34) passes through the seat from the rear, The back image (33) can be seen through the smoke board. At that time, ambient light is blocked by the smoke plate installed on the front of the apparatus, and the symbols on the front side of the seat are hardly visible.

As a result, it is possible to make a device that can show both front and back symbols regardless of ambient brightness. Therefore, if this principle is used, even in a bright room, the day and night scenery can be switched and enjoyed without darkening the room.
The smoke plate can be replaced with a colored transparent plate or a half mirror.

As shown in FIG. 14, a thin transparent plate (38) is provided between the sheet (36) and the light source (37) in the apparatus, and light from another light source (39) is put into the transparent plate from the side. Since the light (40) entering from the side travels while totally reflecting through the transparent plate, there is no scratch (41) on the transparent plate, or another sheet with fine irregularities is not adhered to the transparent plate. As long as light does not leak along the way.

In other words, if a sheet with scratches or fine irregularities is pasted on the transparent plate in advance, only that location can be illuminated (42) and viewed from the front. On the other hand, the light (43) from the light source (37) in the apparatus passes through the transparent plate as it is regardless of the presence or absence of scratches.

If the color of the newly provided light source (39) is changed or blinked, it is possible to change the design of the front and back and simultaneously to make part of the design blink or change the color. For example, when the day scene changes to the night scene, it is possible to blink only the part of the building such as an air traffic sign in red.

If it is installed behind an aquarium of ornamental fish, etc., and the light source in the device is interlocked with the lighting of the aquarium, the scenery seen through the aquarium can be changed and it can be developed into a composite display device.

Application to a three-dimensional display device is also possible by providing a light source inside by sticking or printing different patterns on the front and back of a three-dimensional object or by directly drawing it.

If it is waterproofed, it can be used for signboards, such as changing the scenery of a tourist signboard from a daytime view to a night view.

The same effect can be obtained by reversing the light source of the basic structure, using light from outside the device such as sunlight for the backlight, and installing a more powerful light source in the front when the light is interrupted .
