Description

[Detailed description of the invention] This invention combines a thin plate-like liquid crystal thermometer with an advertising medium such as a board, which is widely and effectively used inside trains, trains, buses, etc., and within transportation facilities such as station premises. It is.

Liquid crystal thermometers have traditionally made use of the property of cholesteric crystals, which are liquid crystals (objects that optically exhibit crystalline properties in a liquid phase), that exhibit the interference and reflection phenomenon of light in a specific temperature range. It is applied to the surface of a film or the like to determine temperature based on interference color. And, such a liquid crystal thermometer is
Conventionally, it has been used as a single item or as known from Japanese Utility Model Application Publication No. 52-20395, by pasting it on the back surface of a mirror.

However, if it is attached to the back of a mirror, the glass inhibits heat conduction to the liquid crystal, making it less sensitive to room temperature and making it difficult to accurately display temperature in environments with rapid temperature changes. It was warm.

This invention is a liquid crystal thermometer that is exposed on the surface and installed between advertisements in trains, buses, etc. or on campus, so that many transportation users can adjust the room temperature to its natural state by viewing the advertisement. You can also check the liquid crystal thermometer to know the room temperature, and at the same time check the advertisements in the surrounding area, it will be effective for public transportation users and help save energy. It is intended for this purpose.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is an advertising board having a desired area, and 2 is an advertising material such as a poster attached to an appropriate position on the advertising board 1 by pasting or inserting. 3 is a thin plate-shaped liquid crystal thermometer attached to the central part surrounded by the advertising material 2. The thermometer 3 is formed by screen printing on a plastic film, for example, 2, 6, 10, 12, 14, 16, 1.
8, 20, 22, 24, 26, 28, 30, 3
Display the number 4, which is 4,38. These numbers 4 are for displaying the temperature in degrees Celsius at the location where the billboard 1 is installed, and of course, these numbers 4 are not limited to the above example and can be used to display a desired range as necessary. Can be done. What is shown in the figure shows temperature values printed using liquid crystals with 15 different coloring temperatures, and the numbers indicating the current temperature are printed in green for example, so that they can be seen at a glance. be.

The thermometer 3 is attached by applying an adhesive to the back side of the film and pasting it at a desired position on the advertising board 1.

In addition, what is shown in FIG. 2 is a billboard 1a on which an advertisement material 2 formed by printing or the like is posted on the entire billboard 1.
In such a case, when the advertising material 2 on the advertising board 1a is to be removed due to expiration of the contract, etc., only the advertising material 2 must be removed from the advertising board 1, and a new advertising material 2 must be replaced. The liquid crystal thermometer 3 is displayed on the advertising board 1 and is used again as it is. In this way, since the liquid crystal thermometer 3 once attached to the advertising board 1 is used repeatedly, sponsors who agree with the advertising method planned by the advertising agency can enter into a contract at a low cost.

As described above, the present invention is constructed by arranging a desired poster or other advertising material on the surface of the advertising board, centering on a thin plate-like liquid crystal thermometer similar to the advertising material, so that transportation users can If you look at a billboard to find out the temperature inside a train or inside a station, you will inevitably look at the advertising material around the thermometer, which can have a remarkable advertising effect, and also It also helps save energy by controlling the room temperature using a thermometer.

In addition, while various types of advertising materials are overflowing in each transportation system, it can be used for a long period of time because it maintains the same advertising effect as well as the degree of interest in temperature.

Furthermore, the so-called digital display, which is a feature of liquid crystal thermometers, allows you to accurately tell the temperature at a glance, making it possible to continue to provide easy-to-recognize temperature information to a wide range of people, from infants to the elderly. Because it is a thin plate, there is no need to worry about bulk or weight, and it can be displayed on billboards just like advertising materials.
Furthermore, there is no danger of falling off or the like. Therefore,
The present invention has a wide range of uses as an advertising medium that is relevant to people from all walks of life.
