Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display board used for a guide light or a display light and a method for manufacturing the display board.

[0002]

2. Description of the Related Art Conventionally, for example, a display panel of a guide light for guiding an evacuation exit or the like, or a display light for displaying a parking lot, etc., is formed of a material such as acrylic to form a semitransparent plastic panel, and its surface is formed. It is manufactured by applying a process (lamp image removal process) that suppresses the light in the high-brightness area facing the light source, and by applying silk printing or a cutting sheet.

[0003]

By the way, in the above-mentioned conventional display panel and the manufacturing method thereof, even if the lamp image removing process is performed, only the dot printing is performed on the portion facing the light source of the display panel. However, the parts that are likely to become shadows (the parts where the light is hard to reach) remain as they are, and the overall uniformity is poor. It is difficult to see the letters and patterns that are present.

Further, in the case of displaying multi-colors on the display plate, printing and drying are repeated for each color on the display plate, so that the number of manufacturing steps of the display plate is large and the display plate varies. It was difficult to manufacture without.

The present invention has been made in view of the above circumstances, and aims at improving the overall uniformity of the display plate, improving the visibility of the display plate, and reducing the number of manufacturing steps of the display plate to provide multicolor display. Even in this case, it is an object of the present invention to provide a guide plate of a guide light or a display light that can be realized with high quality and a manufacturing method thereof.

[0006]

The above object of the present invention can be achieved by the following items (1) to (3).

(1) On one surface of the film-shaped base member, at least a dot pattern layer and an amitene pattern layer having a lower density in order from a high-luminance portion facing the light source, and a portion facing the light source. A white gradation pattern layer and a white pattern layer, which are made lighter in order from a high brightness portion, and a character pattern layer are laminated to form a print layer, and a film-shaped base member having the print layer is formed to form a display board. A method of manufacturing a display panel, comprising applying the print layer to a panel and transferring the print layer to the panel.

(2) On one surface of the film-shaped base member, at least a dot pattern layer and an amitene pattern layer having a lower density in order from a high-luminance portion facing the light source, and a portion facing the light source. The light-colored white gradation pattern layer and the white pattern layer, and the character pattern layer are sequentially laminated to form a print layer, and a film-shaped base member having the print layer is formed on the panel of the display board. A method for manufacturing a display plate, which is arranged in a forming die to be formed and is formed by transferring the printing layer to the panel at the same time as forming the panel of the display plate.

(3) A dot pattern layer and an amitene pattern layer in which the density is sequentially reduced from the high-luminance portion located at least facing the light source on the surface of the synthetic resin panel,
A display board, comprising: a white gradation pattern layer and a white pattern layer, which are lightened in order from a high-luminance portion facing a light source, and a printing layer in which a character pattern layer is laminated.

[0010]

According to the above construction of the present invention, each ink layer forming the surface of the display plate is formed on the film-shaped base member and transferred to the panel forming the display plate. The manufacturing process for forming the surface of the plate is performed only once, and it is possible to reduce the manufacturing process of the display plate, and it is possible to realize high quality even in multicolor display.

Further, in addition to the dot pattern layer and the amitene pattern layer for the lamp image removing process, a white gradation pattern layer and a white pattern layer are further formed, and the lamp cannot be removed by the dot pattern layer and the amitene pattern layer. The image is removed more reliably, and the transmittance is low in the high-brightness area where the lamp is located.
The dark part away from the lamp has high transparency,
This makes it possible to obtain a display plate having a high degree of uniformity and good visibility such as appearance and visibility.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view for explaining the structure of a display panel immediately after it is manufactured by the method for manufacturing a display board according to an embodiment of the present invention. The display board of this embodiment is an example of a display board used for an escape exit light.

A. Structure of Display Board In FIG. 1, 1 is a rectangular acrylic panel obtained by injection molding a resin such as acrylic resin, and 2 to 9 are print layers 2 transferred to the acrylic panel 1. The printing layer 2 is composed of an adhesive layer 3, a dot pattern layer 4, an amitene pattern layer 5, a white gradation pattern layer 6, a white pattern layer 7, a pattern layer 8, a top coat layer 9 and an ink layer of a release layer 10. Has been done. The printed layer 2 is formed in advance as a multi-layered ink layer on the film (transfer foil) 11 of the base member, and is transferred at the time of injection molding of the acrylic panel 1.

The adhesive layer 3 adheres the printed layer 2 to the acrylic panel 1. When the dot pattern layer 4 and the amitene pattern layer 5 are configured as a guide light (indicator light), the portion having the highest brightness located opposite to the light source such as a fluorescent lamp has the highest density and is kept away from the light source. Is an ink layer in the form of dots and a mesh, which are formed by sequentially increasing the density.

When the white gradation pattern layer 6 and the white layer 7 are constructed as a guide light (indicator light), the high brightness portion located opposite to the light source is dark and becomes lighter as the distance from the light source increases. It is an ink layer formed with ink. Due to each of the dot pattern layer 4, the amitene pattern layer 5 and the white gradation pattern layer 6, the transmittance of the portion of the display plate located in front of the lamp is low and the transmittance of the peripheral portion away from the lamp is high. As a result, the removal of the lamp image is improved, and the peripheral portion, which is difficult for light to reach and is likely to be a shadow, is brightened, and the overall uniformity is improved.

The symbol layer 8 represents the symbol of the display board, and since it is the evacuation guide light in this embodiment, it has the shape of a person as shown. The pattern layer 8 is formed of green ink, but may be formed of a plurality of inks of different colors or may be characters. By doing so, multicolor display is possible. The top coat layer 9 protects the surface of the display plate by giving the display plate hardness. The release layer 10 enables the base film 11 to be released from the top coat layer 9.

B. Manufacturing process of display board The display board having such a structure is manufactured as follows.
FIG. 2 is a side view showing the printing process of the base film 11, and the base film 11 is conveyed in the arrow direction, whereby the peeling layer is formed by the print heads 20 to 23 and the inks 25 to 28 arranged at predetermined intervals. 10-top coat layer 9-design (character) layer 8-white layer 7-white gradation pattern layer 6-amiten pattern layer 5-dot pattern layer 4-adhesive layer 3 and a multilayer ink layer are sequentially formed.

FIG. 3 is a perspective view showing the base film 11 on which the multilayer ink layers are formed in this manner. As shown in this figure, the multilayer printing layers 2 are formed on the base film 11 at regular intervals. Has been done. As shown in FIG. 4, the base film 11 on which the multi-layered printing layer 2 is formed is placed in the mold 51 and the mold 52 of the injection molding machine 50, and the melted acrylic resin is discharged from the nozzle 53. Mold 5
The acrylic panel 1 is formed by injection into the molds 1, 52.

Multi-layer printing layer 2 on base film 11
Is separated from the base film 11 by the molding heat of the acrylic panel 1 and is transferred to the acrylic panel 1 simultaneously with the molding of the acrylic panel 1.

As described above, in this embodiment, in the first step (step of forming the ink layer on the base film 11), the base film 11 is opposed to the light source when the guide lamp (indicator lamp) is formed. The dot pattern layer 4, the amitene pattern layer 5 and the white gradation pattern layer 6 are formed at a high density in a high brightness portion located in the area near the lamp, and the peripheral portion of the substantially white gradation pattern layer 6 is formed in a dark portion away from the lamp. Form only low density.

After the completion of the first step, the second step (the step of forming the acrylic panel 1 and the step of transferring the printing layer 2 to the acrylic panel 1) is performed, and the acrylic panel 1 is formed. At that time, the printing layer 2 of the base film 11 obtained in the first step is transferred to the acrylic panel 1 by the heat when molding the acrylic panel.

As a result, the manufacturing process for the display plate can be carried out once in the second process, and when the white layer 7 or the white gradation pattern layer 6 is used as a guide light (indicator light), It is possible to obtain a display plate having a high degree of uniformity, in which a high-luminance portion facing the light source has a low transmittance and a peripheral portion away from the light source has a high transmittance. Furthermore, in this embodiment, since the color-coded pattern patterns are printed on the base film 11 in the first step, it is possible to realize multicolor display without color shift at low cost.

In the above embodiment, the design is for guiding the evacuation exit, but it is possible to deal with various display contents by preparing some kinds of patterns in advance. Of course. Further, by the combination of the respective layers of the dot pattern layer 4, the amitene pattern layer 5 and the white gradation pattern layer 6 and the pattern of each layer,
Although the uniformity is improved, the combination of the layers, the formation order of the ink layers, and the pattern of the layers are not limited to the examples as long as the uniformity can be improved.

Further, the printing layer 2 of the base film 11 is transferred to the acrylic panel 1 simultaneously with the molding of the acrylic panel 1, but the printing layer 2 of the base film 11 is transferred by thermal transfer after molding the acrylic panel 1. However, the present invention is not limited to this, and any thermoplastic resin or thermosetting resin can be used. .

[0025]

As described in detail above, according to the present invention,
