JPH0650188U - Illuminated display - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] The present invention cannot easily identify the display section under the illumination of daylight or interior lighting, but the display section can be easily identified under the illumination of the light source. Therefore, it is an object of the present invention to provide an illuminating display body that can be easily operated. According to the illuminated display of the present invention, a colored pigment is added and dispersed in a semi-transparent rubber-like elastic body 1, and a light-impermeable colored ink layer 2 and a light-transmitting layer are provided on the back surface of the rubber-like elastic body. The colored ink layer 3 is sequentially printed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an illuminated display, and more particularly to an illuminated display whose display can be easily identified only when illuminated.

[0002]

[Prior art]

 As shown in FIG. 2, the illuminated type display that is printed on a semi-transparent rubber-like elastic body has a light-impermeable ink on the surface of the elastic body 11 in which a colored pigment is added to the semi-transparent rubber-like elastic body. 12 is printed and light is emitted from the light source 13 below this, or as shown in FIG. 3, the semi-transparent rubber-like elastic body 21 is provided with no colored pigment and the back surface thereof is not added. It is known that a light-impermeable coloring ink 22 and a light-transmitting coloring ink 23 are combined with each other for printing, and light is emitted from a light source 24 below this.

[0003]

[Problems to be solved by the device]

 However, this known display body has a drawback that it is difficult to judge or operate in daylight or in an environment with illumination such as an interior light because all the displays can be easily identified even when not illuminated. .

[0004]

[Means for Solving the Problems]

 The present invention relates to an illuminated display panel that solves these drawbacks, in which a colored pigment is added and dispersed in a semi-transparent rubber-like elastic body, and the back surface of the rubber-like elastic body is impermeable to light. The coloring ink layer and the light-transmitting coloring ink layer are combined and printed.

That is, the inventors of the present invention have conducted various studies to develop an illuminated display panel that is difficult to identify when not illuminated but can be easily identified when illuminated, and as a result, a semi-transparent rubber-like elastic body has a colored pigment. Was added and printed on the back side with a combination of a light-impermeable colored ink and a light-transmissive colored ink to form a display body. It was found that the display part was difficult to identify when viewed with a line, and it was possible to easily identify the display part by irradiating it with light from the bottom of the display part. We have confirmed that a good display can be obtained and completed the present invention. This will be described in more detail below.

[Action]

 The present invention relates to an illuminated display, which comprises adding and dispersing a colored pigment to a semi-transparent rubber-like elastic body, and also providing a light-impermeable colored ink layer and a light It is characterized by being printed with a combination of transparent colored ink layers. According to this, it is difficult to identify the display when not illuminated, but the display can be easily identified when illuminated. The advantage is given that a plate can be obtained.

As described above, the illuminated display of the present invention comprises adding and dispersing a colored pigment to a semi-transparent rubber-like elastic body, and at the same time, providing a light-impermeable colored ink layer and a light Printing is performed by combining a transparent colored ink layer, which is formed, for example, as shown in FIG. 1, which is a longitudinal sectional view of the illuminated display of the present invention.

The illuminated display body of the present invention shown in FIG. 1 is mainly composed of a translucent rubber-like elastic body 1 such as silicone rubber formed by molding such as injection molding or compression molding, for example, phthalocyanine, It is said that color pigments such as blue and black color such as carbon black are added and dispersed.The kind of this color pigment may be determined depending on the application, and the addition amount depends on the color of the display part, visibility, and application. It may be determined so that the light amount is appropriately attenuated.

Therefore, the rubber-like elastic body is provided with a light-impermeable colored ink layer 2 provided on its back surface by, for example, screen printing or tampo printing, and a light produced by, for example, screen printing or tampo printing. Printing is performed with a combination of the transparent colored ink layers 3. The type of color of the light-impermeable colored ink layer used here may be determined depending on the application, but this ink layer must be formed in a state where the display portion is omitted. Further, this light-transmitting colored ink layer serves as a display portion for characters, symbols, numbers, etc. The kind of this color may be determined according to the application, but this light-transmitting property is a rubber-like elastic body. The absorptivity of the light may be determined according to the attenuation of the light amount of the above, so that it is difficult to distinguish the above-mentioned light-impermeable colored ink layer from the reflected light. In FIG. 1, the rubber elastic body 1 is provided with the light-transmitting colored ink layer 3 via the light-impermeable coloring ink layer 2 as a desirable mode. The colored ink layer 2 may be provided on the rubber elastic body 1. For example, the colored ink layer 2 and the colored ink layer 3 may be laminated on the rubber elastic body 1 in this order unless the transparency is deteriorated. You may.

When the illuminated display body of the present invention having the above-described structure is visually observed by reflected light under daylight or under room light, the light is reflected when the light enters the display body and is reflected. In addition to being diffused and absorbed according to the blending amount of the colored pigment added and dispersed in the rubber-like elastic body, this is also absorbed by the light-transmitting colored ink layer, making the display difficult to identify. However, when the light source 4 installed at the bottom of this display is turned on and illuminated by this, only the incident light that is transmitted is absorbed, and the amount of attenuation is small, so that only the easily illuminated display part is displayed. Are thus identified, which provides the advantage of providing a display with good operability and without misinterpretation of the display.

It should be noted that the rubber-like elastic body 1 in the illuminated display body of the present invention may be patterned on its surface by etching or the like, or it may be provided with irregularities in shape. It may be provided with a thin portion to have a key shape. The light-impermeable color ink layer 2 and the light-transmissive color ink layer 3 may be formed by painting, or the light source 4 may be colored, and the colored light is used. In some cases, the light-transmitting colored ink layer may not be formed.

[Effect of device]

 The present invention relates to an illuminating display, which comprises adding and dispersing a colored pigment to a semi-transparent rubber-like elastic body as described above, and applying a light-impermeable colored ink to the back surface of the rubber-like elastic body. It is characterized in that it is printed by combining a layer and a light-transmitting colored ink layer.However, this one can be identified by the display under the environment with illumination such as daylight and room light. This is difficult, but when illuminated by a light source located below this, this display can be easily identified, which provides the advantage of improving this operability.
