Abstract

PURPOSE:To execute a satisfactory display without interfering with a field of view of the outside and natural lighting to the inside by allowing a transparent display body to appear as a display part, when a relative position to the fixed polarizing body of a variable polarizing body becomes an overlapped position. CONSTITUTION:The fixed polarizing body 1 is formed by a transparent base body 1a made of achromatic transparent hard glass, and by sticking a chromatic transparent polarized light film 1b of a light color to its outside, and to the outside of the polarized light film 1b, an achromatic transparent display body 3 for varying a phase of the polarizing body such as cellophane, etc. On the other hand, a movable polarizing body 2 is, for instance, a window part of an electric car, and formed by sticking a polarized light film 2b to the inside of a vehicle of the electric car of a transparent base body 2a. In this state, only when a relative position to the fixed polarizing body 1 of the variable polarizing body 2 becomes an overlap position, the transparent display body 3 is allowed to appear as a display part from the fixed polarizing body. In such a way, a satisfactory display can be executed without interfering with the field of view to the outside and natural lighting to the inside.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a display method using a polarizer, and is applied to windows of vehicles such as railways and mole rails, windows (walls) of station buildings, or observation elevators. - It is used for things equipped with a movable body and a fixed body, such as a window part (1 part) of a building.

<Prior Art> Conventionally, waiting rooms provided on station platforms had windows (walls) surrounded by transparent glass or the like so that trains etc. that stopped at the platform could be easily seen. In addition, the walls of the observation elevator were made of transparent glass so that the outside color could be clearly seen.

<Problems to be solved by the invention> However, when attempting to display station names, advertisements, and other information in the above-mentioned conventional train stations and observation elevators, paint is applied to the top surface of the transparent glass to display the information. Alternatively, a method of displaying by pasting colored display tape or the like was used. However, both of the above methods have the disadvantage that the display section acts as a light shield, making it difficult to see the outside and reducing the amount of light entering the waiting room or the like. Therefore, transparent bodies such as those in waiting rooms were not often provided with display sections.

Means for Solving the Problems> The present invention was made in view of the above problems, and usually, a colorless or colored transparent fixed polarizer and a movable polarizer are placed in an overlapping position. It is an object of the present invention to provide a display method in which a transparent display body fixed to at least one polarizing body appears as a display part only at certain times.

This invention consists of a fixed polarizing body, a movable polarizing body, and a transparent display body that is attached to at least one of the leaking light bodies and changes the phase of the polarizing body on the attached part, and the fixed polarizing body of the movable polarizing body The above-mentioned problems are solved by causing the transparent display body to appear as a display section from the fixed polarizing body only when the relative position with respect to the body reaches an overlapping position.

Fixed polarizers are installed in the windows (walls) of waiting rooms on station platforms, or in the windows (walls) of buildings outside observation elevators, and are colorless on transparent substrates such as glass. Or one with a colored polarizing film attached,
Alternatively, a polarizing plate itself can be used.

On the other hand, movable polarizers are installed in the windows of vehicles such as railways and mole rails, or the windows and walls of observation elevators, and can be attached with a polarizing film in the same way as above, or they can be used as polarizers themselves. can be used.

The transparent display is a material that displays characters, pictures, etc. and changes the phase of the polarizer to which it is pasted. It is made of a thin sheet-like material and is pasted on the side between the fixed polarizer and the movable polarizer. It is worn.

<Functions and Effects> The transparent display is colored and transparent with the same color as the polarizer to which it is attached, or is colorless and transparent, so when it is attached to the polarizer alone, it acts as a protective color, so special care must be taken. Unless you look closely, you won't be able to tell if the transparent display is attached. Therefore, even if a transparent display material is attached, the display area will not be exposed if only the fixed polarizer or movable polarizer is used, but the display area will not block light and the outside mother color etc. can be clearly seen. Can be done. Further, the transparent display body changes the phase of the polarizer in the attached portion by attaching itself to a movable or fixed polarizer. When the flexible ea light body is in a position overlapping the fixed polarizer, the phase of the polarizer in the part where the transparent display body is attached is different from that in the part where the transparent display body is not attached, so it becomes transparent. The display body can be made to appear from the polarizer as a display section.

<Example> Hereinafter, an example of the display method of the present invention will be described based on the drawings.

FIG. 1 is an explanatory perspective view of a main part of this embodiment, and FIG. 2 is a front view of this embodiment in the direction of arrow A in FIG. 1.

The fixed polarizer 1 of this embodiment is a wall part of a waiting room provided on a platform of a railway station, etc., and includes a transparent substrate 1a made of colorless and transparent hard glass, and a light colored transparent substrate 1a on the outside thereof. It is formed by pasting a polarizing film 1b. A colorless and transparent display material 3 that changes the phase of a polarizing material such as cellophane is attached to the outside of the polarizing film 1b. This transparent display body 3 represents the station name, etc., and is formed by punching a colorless transparent sheet. In addition, since the transparent display body 3 is colorless and transparent, even if it is attached to the outside of the H-light film 1b, it will appear as if nothing is attached, and it will not obstruct the view of the outside scenery. Moreover, it does not obstruct daylighting into the waiting room.

On the other hand, the movable polarizer 2 is a window of a train, and the polarizing film 2b is attached to the inside of the train car of the transparent base 2a in the same manner as described above. In addition, the above polarizing films 1b and 2b
are in phase.

Next, the functions and effects of this embodiment will be explained.

Since the fixed polarizing body 1 and the transparent display body 3 as the walls of the waiting room have the above-described structure, a person holding a train in the waiting room can see the scenery outside without any hindrance. Also,
Daylighting into the waiting room is also possible without any problems. On the other hand, since the window of the train serving as the movable polarizer 2 is simply pasted with a light colored transparent polarizing film 2b, there is no problem in viewing the outside scenery from inside the train. There is also sufficient lighting. Then, when the train stops at the station platform and the movable polarizer 2 and the fixed polarizer 1 overlap, one polarizer 2 (1) is passed through the other polarizer 1.
If you look at <2), for example, as shown in Figure 2, a person on a train may see the waiting area v through the window glass (2).
When you look at (1), the part where the transparent display body 3 is attached, which is placed between the double-width light bodies 1 and 2 and is out of phase with the double-width light bodies, appears as the station name, and when you get on the train, People who are there can know the station name. People in the waiting room can also see the station name only in the part that overlaps with the train window.

Therefore, there is usually no display on the wall of the waiting room, there is no hindrance to seeing the outside scenery, there is sufficient lighting inside the room, and when the train is stopped, the movable polarizer 2 and the fixed polarizer The display body 3 appears only when the body 1 and the body 1 are in the same position, and people on the train and in the waiting room can see the station name, etc.

Note that the present invention is not limited to the above embodiments, and can be applied to objects that can be used as movable polarizers and fixed polarizers, such as buses and bus stops (shelters), observation elevators, and windows of buildings surrounding them. It can be applied to

Furthermore, although the above embodiments have shown a fixed polarizing body provided with a transparent display body, the transparent display body may be provided on a movable polarizing body (or may be provided on both polarizing bodies).

In addition, in the above embodiment, the transparent display was partially provided for the station name, etc., but a transparent display was pasted on the entire lower half of the wall of the observation elevator to prevent people from peeking from below. A display body can also be used as a shield.

Furthermore, in the above embodiment, the movable vJ polarizer and the fixed polarizer were used in the same phase to make the area where the transparent display body was attached stand out, but as shown in FIG. By using a movable polarizer and a fixed polarizer with a phase difference of 90 degrees, and pasting a transparent display material,
If the phase of the polarizer at the attachment site is further changed by 90 degrees, the transparent display body can be displayed as if the attachment site is hollowed out.

Furthermore, in the above embodiment, a polarizing film was attached to one side of a transparent substrate as a polarizing body, but if a transparent display body that changes the phase is arranged between both width light bodies, it is possible to Any polarizer can be used, such as one formed by sandwiching a polarizing film between transparent substrates.
