Description

[Detailed explanation of the invention] [Purpose of the invention] (Industrial application field) This invention is based on pasting a light regulating film on the back side of a translucent sheet on which display parts such as letters and marks have been printed by stamping. Regarding the display board.

(Prior Art) Display boards, such as switch display boards used in automobile panels, have characters or marks that are made to float at night using light from a light source such as a lamp placed behind the display board. In this case, a light regulating film is attached to the back surface of the translucent sheet on which the characters or marks are printed to prevent light from scattering from the characters or marks. With this device, the characters or marks are made visible during the daytime when the light source such as a lamp is not lit, using natural light from outside.

(Problem to be solved by the invention) Conventionally, a black light-shielding printed film with cut-out characters or marks was applied to the front side of a translucent sheet, and a black printed film with cut-out characters or marks was applied to the back side of the translucent sheet. A white printed film was formed on the surface of the louver of the light regulating film in contact with it. With this conventional configuration, when the characters or marks on the display board are viewed with natural light from outside during the day, the white printed film attached to the surface of the louver is seen through the cutout of the characters or marks. In some cases, there was a problem that the characters or marks seemed dark and difficult to see.

Therefore, the purpose of the present invention is to make it easier to see the characters or marks on the display board during the daytime using natural light from outside.
To provide an improved display board that is bright and easy to see.

[Structure of the invention] (Means for solving the problem) The present invention involves pasting a light-adjusting film with louvers on the front side to the back side of a translucent sheet. in which light from a light source placed behind the light transmitting sheet is applied to the light transmitting sheet through the light regulating film, white printing is applied to the surface side of the louver of the light regulating film, and the light transmitting sheet The present invention is characterized in that a matte clear print is applied to the front side of the translucent sheet, and display portions such as letters and marks are applied to the back side of the translucent sheet by cut-out printing.

(Function) According to the above-described means, the part where characters, marks, etc. are printed on the translucent sheet and the white printing on the louver of the light regulating film are on substantially the same surface. Because the white printing area is located in
Bright and easy to see.

(Example) Hereinafter, an example in which the present invention is applied to a switch display board for an automobile will be described with reference to the drawings.

Reference numeral 1 denotes a light-transmitting sheet made of polycarbonate, and a light-adjusting film 3 having a louver 2 attached to the front side is attached to the back side of this sheet by, for example, adhesive. A printed film 4 with matte clear printing is provided on the surface of the translucent sheet 1. On the back side of the translucent sheet 1, the letters "A/C" 5 serving as a display part and a horizontally long rectangular mark 6 are printed by overlapping black and white printing using a screen cutout. It is formed by forming the character 5 and the mark 6.
It is designed so that no light can pass through it from any other direction. A white printed film 8 is attached to the front surface of the louver 2, and a black printed film 9 is attached to the other surfaces. Further, on the back surface of the light regulating film 3, a translucent blue printed film 10 is attached to a portion corresponding to the letters 5. Reference numerals 11 and 12 denote lamps serving as light sources disposed below the light regulating film 3, with the lamp 11 facing the character 5;
The lamp 12 faces the mark 6.

Next, the operation of the above configuration will be explained. The lamp 12 is turned on when an air conditioner switch (not shown) is turned on. Further, the lamp 11 is turned on when a tail switch (not shown) is turned on at night. When the lamp 11 is turned on, the light that passes through the light regulating film 3 via the printed film 10 is not scattered, but passes through the letters 5, the translucent sheet 1, and the printed film 4, making the letters 5 stand out in blue. let When lamp 12 is lit,
The light that has passed through the light regulating film 3 is not scattered, but is transmitted through the mark 6, the translucent sheet 1, and the printing film 4, making the mark 6 stand out.

On the other hand, during the daytime when the lamp 11 is not lit,
Light from the outside reaches the printing film 7 via the printing film 4 and the translucent sheet 1, and is reflected by the white printing film 8 on the surface of the louver 2 through the cut-out printed characters 5. The white printing film 8 can be visually observed from the outside in the shape of the printed characters 5.

As described above, according to this embodiment, since the printed film 7 on which the characters 5 are printed is located adjacent to the white printed film 8 attached to the surface of the louver 2, the light reflected by this printed film 8 is Most of the light passes through the translucent sheet 1 and the printed film 4, making it brighter and easier to see when viewed with the naked eye. On the other hand, in the conventional case, the stamped mark part and the white printed film of the louver are separated by the thickness of the translucent sheet, so the white light enters from the mark part. Only a portion of the light reflected by the printing film could pass through the mark again, and the white part was sunk deep from the mark, making it dark and difficult to see when viewed with the naked eye.

[Effects of the invention] As is clear from the above explanation, the present invention involves pasting a light-adjusting film with louvers on the front side to the back side of a translucent sheet, so that the light-adjusting film can be used at night, etc. In the device in which light from a light source placed at the rear is applied to the light-transmitting sheet through the light-stabilizing film, white printing is applied to the surface side of the louver of the light-stitching film, and the light-transmitting sheet is It is characterized by applying matte clear printing on the front side of the sheet and also applying display parts such as letters and marks on the back side of the transparent sheet by cut-out printing. Because the area where markings and other display parts are stamped and the white printing applied to the louver of the light-stabilizing film are located on approximately the same surface, external light rays do not reach the white printing area. Easy,
To provide an excellent effect of making characters or marks on a display board bright and easy to see when viewing them with natural light from outside during the day.
