Description

  TECHNICAL FIELD The present invention relates to a laminated sheet for information display panels provided with front and back printed layers, and in particular, a laminated sheet for information display panels having light shielding properties and light reflecting properties of a light shielding layer and a reflective layer, an information display panel, and an information display panel thereof It is related with the transport equipment which equipped.

Although many measuring instruments are mounted on transport equipment, there is a demand not only for visibility but also for design for information display panels used in such displays.
As a conventional information display panel, a chromatic light-shielding reflective layer including an opening and a white transmissive reflective layer are sequentially laminated on a portion corresponding to characters / pictures on the back of a transparent substrate, and a white layer and a dark color layer are formed on the surface. Are sequentially stacked, and there is a structure in which a portion corresponding to a character / picture is an opening.

  By using the configuration of the information display panel described above, when the lamp is not lit, the light / character portion is visually recognized as white surrounded by a chromatic color, and the surroundings of the character / image are visually recognized as dark. In addition, when the lamp is lit, white light is transmitted through the white transmissive reflective layer, and the white light passing through the opening of the chromatic light-shielding reflective layer is visually recognized. The light is reflected again by the chromatic light-shielding / reflective layer on the back surface, passes through the opening on the front surface, and is visually recognized as chromatic indirect light (Patent Document 1).

  However, although the conventional technology expresses the three-dimensional effect of characters and pictures with chromatic indirect light and white direct light when the lamp is lit, the color remains the same as when observing with external light when the lamp is not lit, It was not illuminated and could not be expressed with color changes.

It is sectional drawing of the lamination sheet which concerns on the 4th Embodiment of this invention.

  Exemplary embodiments of an information display panel according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of a laminated sheet 18 for an information display panel according to a first embodiment of the present invention, taken along a plane perpendicular to the sheet extending direction. (A) shows each layer separated for easy understanding of the order of lamination, and (B) shows a state in which the layers are actually laminated.
As shown in FIG. 1, the laminated sheet 18 is divided into a first region 1, a second region 2 and a third region 3 which are adjacent to the first region 1 and separated from each other.
A design shape such as a pattern is configured by the shapes of the first to third regions on the extending surface of the laminated sheet 18.
Note that other regions apart from the second and third regions may be further provided. In that case, the first region is disposed adjacent to the further provided region.
In FIG. 1, an observer 21 views from one surface side of the light transmissive support 4, and the light source 19 is installed on the other surface side of the support 4.
A first reflective layer 7, a first light-shielding layer 8, and a light-transmitting colored layer 9 are laminated in a predetermined region on the light source side surface of the support 4, and a predetermined surface on the viewer 21 side surface of the support 4. The 2nd reflective layer 5, the 1st decorating layer 6, the 2nd decorating layer 10, and the 4th decorating layer 13 are laminated | stacked on the area | region.

The support body 4 can be comprised only by transparent resin, can be comprised only by diffusible resin, or can be comprised by lamination | stacking of a transparent resin layer and a diffusible resin layer.
Here, the haze value of the support 4 is desirably 12% or more and 92% or less.
When the haze value of the support 4 is less than 12%, the light that enters the support 4 and diffuses and reflects and passes through the first region 1 is reduced, which causes a disadvantage that the brightness of the indirect light is reduced. It is.

  When the support 4 is composed only of a transparent resin, polycarbonate, polypropylene, expanded polypropylene, polyethylene terephthalate, polystyrene, methacryl / styrene copolymer, acrylonitrile / styrene copolymer, polymethyl methacrylate or acrylic may be used. it can. The thickness of the support 4 at this time is preferably 0.1 mm or more in order to cause a large amount of light diffusely reflected by the second reflective layer 5 to advance to the first region 1, and is a spatial constraint in the information display device casing. Is preferably 5 mm or less. Further, since the loss of the light amount in the support 4 can be reduced if it is composed only of the transparent resin, it is possible to display characters and designs brighter when the light source 19 is turned on.

  When the support 4 is composed only of a diffusible resin, it is a spherical or amorphous shape, and an organic resin containing at least one of polycarbonate, PS, MS, and acryl containing organic or inorganic light diffusing fine particles. Can be used. The thickness of the support 4 at this time is preferably 0.1 mm or more in order to cause a large amount of light diffusely reflected by the second reflective layer 5 to advance to the first region 1, and is a spatial constraint in the information display device casing. Is preferably 5 mm or less. Further, by constituting only the diffusible resin, a part of the direct incident light from the light source 19 is diffused by the diffusible resin and is emitted in the direction of the observer 21 in the first region 1. Enhanced.

When the support 4 has a laminated structure of a transparent resin layer and a diffusible resin layer, the transparent resin layer has polycarbonate, polypropylene, expanded polypropylene, polyethylene terephthalate, polystyrene, methacryl / styrene copolymer, acrylonitrile / styrene copolymer. Polymer, polymethyl methacrylate or acrylic, and the diffusible resin layer is spherical or amorphous in shape, polycarbonate, polystyrene, methacryl / styrene copolymer, acrylic containing organic or inorganic light diffusing fine particles An organic resin containing at least one of them can be used. The thickness of the support 4 at this time is preferably 0.1 mm or more in order to cause a large amount of light diffusely reflected by the second reflective layer 5 to advance to the first region 1, and is a spatial constraint in the information display device casing. Is preferably 5 mm or less. In addition, since the configuration includes the diffusible resin layer, part of the direct incident light from the light source 19 is diffused by the diffusible resin layer and further diffusely reflected by the first reflective layer 7. Therefore, the amount of indirect light can be increased.
Here, the diffusible resin layer is preferably a resin having a haze value of 12% or more and 92% or less. When the haze value of the diffusible resin layer is less than 12%, the light that enters the support and diffuses and reflects and passes through the first region 1 is reduced, so that the luminance of indirect light is lowered. Because.

Next, the laminated structure on the viewer 21 side of the support 4 will be described.
The second reflective layer 5 is laminated on the second region 2 and the third region 3 on the surface of the support 4 on the viewer 21 side.
As described above, when another region apart from the second and third regions is further provided, the reflective layer 5 is also laminated in that region.
The second reflective layer 5 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
The second reflective layer 5 has the effect of diffusely reflecting incident light with a predetermined probability.
Although it is desirable to use white ink for the second reflective layer 5, it is not limited to white ink as long as it has a light reflection effect and transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a reflective effect will come out easily.
Further, the reflectance of light of 380 to 780 nm in the second reflective layer 5 is preferably 60% or more and 95% or less, and the total light transmittance of the second reflective layer 5 is desirably 5% or more and 40% or less. .
When the reflectance of the second reflective layer 5 is less than 60%, the brightness of the indirect light reflected by the second reflective layer 5 is reduced, and the boundary between the first region 1 and the second region 2 is reduced. This is because the stereoscopic effect is impaired. In addition, when the total light transmittance of the second reflective layer 5 is less than 5%, when an opening having a design shape such as a character is provided in the first decorative layer 6, the luminance of the portion is low, and the character This is because the iso-design shape is not visually recognized. On the other hand, if the total light transmittance is 40% or more, the reflectance is lowered, and as described above, the stereoscopic effect at the boundary between the first region and the second region is lowered due to the luminance reduction of the indirect light. is there.
When the light source 19 is turned on, the light diffusely reflected by the second reflective layer 5 is visually recognized as indirect light in the first region 1. At this time, the larger the width of the second reflective layer 5 in the second region 2 and the third region 3 is, the more the light is diffused and reflected toward the first region 1, so that the luminance is increased. The stereoscopic effect of region 1 of 1 is increased. When a design shape such as a character is provided inside the second region 2, light transmitted without being diffusely reflected by the second reflective layer 5 passes through an opening of the first decorative layer 6 described later. Thus, the design shape such as letters is visually recognized as direct light from the observer 21.
A first diffusion layer having a haze value of 5% to 90% and a total light transmittance of 60% to 98% may be further provided between the support 4 and the second reflective layer 5. In this numerical range, when the haze value of the first diffusion layer is less than 5%, the effect of diffusing and reflecting the incident light to the first diffusion layer to the first region 1 cannot be sufficiently obtained. When the total light transmittance of the diffusing layer is less than 60%, the amount of light incident on the second reflective layer 5 is reduced, so that the brightness of the reflected light to the first region 1 is reduced and the stereoscopic effect is impaired. Is taken into account.

In the second region 2, the first decorative layer 6 is laminated on the surface of the second reflective layer 5 on the viewer 21 side.
The first decorative layer 6 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing. Although it is desirable to use black ink for the 1st decoration layer 6, if there is a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
Moreover, it is desirable that the total light transmittance of the first decorative layer 6 is substantially constant in the range of 0% to 20%.
When the total light transmittance is larger than 20%, the transmitted light of the second reflective layer 5 in the second region 2 cannot be shielded, and the contrast between the first region 1 and the second region 2 decreases. This is because the three-dimensional effect is impaired.
The first decorative layer 6 represents the pattern in the second region 2 and blocks light from the light source 19 that is transmitted without being diffusely reflected by the second reflective layer 5. In addition, when it is desired to provide a design shape such as a character inside the second region 2, an opening having a design shape such as a character may be provided in the first decorative layer 6. The light transmitted through the second reflective layer 5 without being diffusely reflected passes through the opening where the first decorative layer 6 is not laminated, so that the design shape such as letters can be visually recognized directly by the observer 21 with light. .
The opening is not necessarily provided, but is provided when necessary in terms of design.

In the third region 3, the second decorative layer 10 may be laminated on the viewer 21 side of the second reflective layer 5. The second decorative layer 10 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing. Although it is desirable to use black ink for the 2nd decoration layer 10, if there is a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
Moreover, it is desirable that the total light transmittance of the second decorative layer 10 is substantially constant in the range of 0% to 20%. When the total light transmittance is greater than 20%, the transmitted light of the second reflective layer 5 in the third region 3 cannot be shielded, and the contrast between the first region 1 and the third region 3 decreases. This is because the three-dimensional effect is impaired.
The second decorative layer 10 represents the pattern in the third region 3 and blocks the light of the light source 19 that is transmitted without being diffusely reflected by the second reflective layer 5.
In the first region 1 where the second reflective layer 5 is not provided, a second diffusion layer having a haze value of 5% to 90% and a total light transmittance of 60% to 98% may be further provided. . In this numerical range, when the haze value of the second diffusion layer is less than 5%, the effect of diffusing and reflecting incident light to the second diffusion layer to the first region 1 cannot be sufficiently obtained. This is because when the total light transmittance of the diffusion layer is less than 60%, the brightness of the indirect light that is visually reflected by the first reflection layer 7 is lowered, and the stereoscopic effect is impaired.

Next, the laminated structure on the light source 19 side of the support 4 will be described.
The first reflective layer 7 is provided in the first region 1 on the light source 19 side of the support 4.
The first reflective layer 7 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
The first reflective layer 7 has an effect of diffusely reflecting incident light with a predetermined probability.
Although it is desirable to use white ink for the first reflective layer 7, it is not limited to white ink as long as it has a light reflection effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a reflective effect will come out easily.
Further, the reflectance of the light of 380 to 780 nm in the first reflective layer 7 is desirably 40% or more and 98% or less.
This is because when the reflectance of the first reflective layer 7 is less than 40%, the luminance of the indirect light reflected by the first reflective layer 7 is lowered, and the stereoscopic effect is impaired.
When the light source 19 is turned on, the light reflected by the second reflective layer 5 is re-reflected by the first reflective layer 7 and escapes to the viewer 21 side of the first region 1, thereby providing a three-dimensional effect. Make it.

In the first region, the first light shielding layer 8 is laminated on the light source 19 side of the first reflective layer 7.
The first light shielding layer 8 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use black ink for the first light shielding layer 8, it is not limited to black ink as long as it has a light shielding effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
The total light transmittance of the first light shielding layer 8 is desirably 0% or more and 20% or less. When the total light transmittance of the first light-shielding layer 8 is greater than 20%, the incident light of the first light-shielding layer 8 cannot be shielded, and direct light is visually recognized in the first region, so that the indirect light is visible. This is because there is a detrimental effect that the three-dimensional effect is deteriorated due to a decrease in the image quality.
Since the first light shielding layer 8 shields light when the light source is turned on, direct light does not pass through the first region 1. Thereby, the visibility in the 1st area | region 1 of the indirect light reflected by the 2nd reflective layer 5 of the 2nd area | region 2 and the 3rd area | region 3 is improved, and a character, a picture, etc. are displayed beautifully.

In the second and third regions where the first light shielding layer 8 is not laminated, the light transmissive colored layer 9 is provided on the light source side of the support 4. In particular, the present invention is not limited to the second and third regions, and may be laminated as a whole including the first light shielding layer 8 as shown in FIG. .
The light transmissive colored layer 9 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
The light-transmitting colored layer 9 is preferably made of light-transmitting chromatic ink, but is not limited to this as long as a light-transmitting chromatic color layer can be provided.
The light-transmitting colored layer 9 preferably has a total light transmittance of 20% or more and 90% or less. When the total light transmittance of the light-transmitting colored layer 9 is less than 20%, the brightness of the indirect light that is incident on and reflected by the second reflective layer 5 is reduced, resulting in a stereoscopic effect. This is because there is a harmful effect of being damaged.
Since the light that has passed through the light-transmissive colored layer 9 when the light source is turned on is reflected by the second reflective layer 5 and the first reflective layer 7 and is visually recognized as indirect light in the first region 1, indirect light Depends on the color of the light-transmitting colored layer 9. By making the light-transmitting colored layer 9 an arbitrary color, characters, pictures and the like are displayed beautifully.
When a design shape such as a character is provided inside the second region 2, an opening can be provided in a region slightly larger than a portion corresponding to the design shape such as the character of the light-transmitting colored layer 9. When the light-transmitting colored layer 9 is provided with an opening, direct light does not pass through the light-transmitting colored layer 9 when the light source is turned on, so that the design shape such as letters directly from the observer 21 depends on the second reflective layer. Visible as light. Here, the reason why the opening of the light-transmitting colored layer 9 is slightly larger than the design shape of characters and the like is to prevent the light transmitted through the light-transmitting coloring layer 9 from interfering with the ends of the design shapes of characters and the like. is there.
Specifically, the opening of the light-transmitting colored layer 9 has an outer periphery that is 0.050 mm or more outside from the outer periphery of the opening of the first decorative layer 6. It is desirable that the outer periphery is separated from the boundary between the second region 2 and the first region 1 by 1.000 mm or more.
When the opening of the light-transmitting colored layer 9 is not 0.050 mm or more outside from the outer periphery of the opening of the first decorative layer, the light visible from the opening of the first decorative layer 6 is white light. This is because there is an adverse effect that the light is visually recognized as chromatic light transmitted through the light-transmitting colored layer 9. In addition, it is not this limitation when the light visually recognized from the opening part of the 1st decoration layer 6 may be a chromatic color on a design.
Further, when the outer periphery of the opening of the light transmissive colored layer 9 is not separated from the boundary between the second region and the first region by 1.000 mm or more, the second reflective layer is formed from the opening of the light transmissive colored layer 9. This is because the indirect light incident on the first region and reflected by the first region is not chromatic.
Note that this opening is not necessarily provided, and it is not necessary to provide an opening if the design shape such as letters when the light source is turned on needs to depend on the color of the light-transmitting colored layer 9 in terms of design. Absent.

A fourth decorative layer 13 is provided in a part of the first region 1 on the viewer 21 side of the support 4.
In FIG. 1A, the decorative layer 13 is displayed on the same level as the first and second decorative layers in order to make it easy to understand the order and type of the layers, but in reality, as shown in FIG. Are laminated on the surface of the support 4 on the viewer 21 side.
The fourth decorative layer 13 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use black ink for the 4th decoration layer 13, if there is a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
In addition, the total light transmittance of the fourth decorative layer 13 is preferably 0% or more and 20% or less.
When the total light transmittance of the 4th decoration layer 13 is larger than 20%, the transmitted light of the 4th decoration layer 13 is visually recognized, and with the part without the 4th decoration layer in the 1st field This is because the contrast is lowered and the visibility of the fourth decorative layer 13 is lowered.
When the light source is turned on, indirect light spreads in the first region 1, but since there is the fourth decorative layer 13 in a part of the first region 1, the portion is shielded and visually recognized as a pattern. . The fourth decorative layer 13 can be provided if necessary in terms of design. Even if the fourth decorative layer 13 is not provided, other functions in the information display panel 20 are not affected.

Thus, the design shape such as letters is visually recognized as direct light from the observer 21.

In the second region 2, the first decorative layer 6 is laminated on the surface of the second reflective layer 5 on the viewer 21 side.
In addition, when it is desired to provide a design shape such as a character inside the second region 2, an opening having a design shape such as a character may be provided in the first decorative layer 6.
The opening is not necessarily provided, but is provided when necessary in terms of design.
The material, creation method, and effects of the first decorative layer 6 are the same as those in the first embodiment described above.

In the third region 3, the second decorative layer 10 is laminated on the viewer 21 side of the second reflective layer 5.
The second decorative layer 10 has the lowest total light transmittance at the boundary with the first region 1 and has a light shielding property, and the total light transmittance gradually increases as the distance from the boundary with the first region 1 increases. It becomes light transmissive.
The second decorative layer 10 can be provided by offset printing. In particular, letterpress printing, flexographic printing, screen printing, gravure printing, inkjet, etc. can be used without being limited to screen printing. Although it is desirable to use black ink for the second decorative layer 10, it is not limited to black ink as long as the gradation expression of the light shielding portion and the light transmitting portion can be expressed. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
When the light source 19 is turned on, the second decorative layer 10 shields the incident light passing through the second reflective layer 5 at the boundary with the first region 1 in the third region 3. As the distance from the boundary with the first region 1 increases, the amount of transmitted light can be increased stepwise.
Specifically, the second decorative layer 10 has a total light transmittance of 0% or more and 20% or less at the boundary with the first region in the third region, and the center of the third region. The layers are laminated so that the total light transmittance in the portion is 40% or more and 100% or less, and the total light transmittance changes stepwise from the boundary toward the center.
When the total light transmittance of the second decorative layer 10 at the boundary between the first region and the third region is greater than 20%, the transmitted light of the second reflective layer 5 cannot be blocked, and the first region and This is because the contrast with the third region is lowered and the stereoscopic effect is impaired. In addition, when the total light transmittance of the second decorative layer in the central portion of the third region is less than 40%, the luminance of transmitted light viewed in the third region is low, and the third region (gradation) This is because it cannot be displayed beautifully.

The third decorative layer 11 is laminated on the viewer 21 side of the second decorative layer 10. The third decorative layer 11 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use silver ink for the 3rd decoration layer 11, if it is translucent, it will not be restricted to silver ink. Although there is no restriction | limiting in thickness, if it is 10 micrometers-30 micrometers, the concealment effect will come out easily.
The total light transmittance of the third decorative layer 11 is preferably 4% or more and 40% or less.
When the total light transmittance of the third decorative layer 11 is less than 4%, the transmitted light of the second decorative layer 10 cannot be visually recognized, and the adverse effect that the pattern of the third region 3 cannot be visually recognized when the light source is turned on. Because there is. On the other hand, when the total light transmittance of the third decorative layer 11 is larger than 40%, the second decorative layer 10 cannot be concealed when the light source is not turned on, and the second decorative layer 11 is turned on when the light source is turned on. This is because there is an adverse effect that the difference in the pattern of the third area 3 cannot be expressed.
When the light source 19 is not lit, the third decorative layer 11 conceals the second decorative layer 10. On the other hand, when the light source 19 is turned on, the third decorative layer 11 transmits the transmitted light of the second decorative layer 10 whose light amount changes stepwise, so that the appearance when the light source 19 is not lit is shown. Can make a difference.

A transparent decorative layer 12 having an arbitrary pattern such as a spin pattern is laminated on the viewer 21 side of the third decorative layer 11.
The transparent decorative layer 12 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
The transparent decorative layer 12 is preferably made of transparent ink. Although there is no restriction | limiting in thickness, if it is 50 micrometers-100 micrometers, it will be easy to visually recognize.
The total light transmittance of the transparent decorative layer 12 is desirably 80% or more and 100% or less.
This is because when the total light transmittance of the transparent decorative layer 12 is less than 80%, the luminance of the third region 3 when the light source is turned on is lowered, which hinders visual recognition.
When the light source 19 is not lit and when it is lit, the third region 3 is beautifully represented by the transparent decorative layer 12 being seen with the third decorative layer 11 as a base.

A first reflective layer 7 is provided in the first region 1 on the light source side of the support 4.

The light transmitted through the light-transmitting colored layer 9 passes through the support 4 from the second and third regions where the first light shielding layer 8 and the first reflective layer 7 are not laminated, and the second reflective layer 5 Part of the light incident on the second reflection layer 5 is reflected by the second reflection layer 5. The light passes through the support 4, is reflected by the first reflective layer 7, and passes through the support 4 toward the observer 21.
Direct light from the light source 19 is shielded by the first decorative layer 6 in the second region 2 except for the character-design-shaped portion, and is shielded by the first light-shielding layer 8 in the first region 1. Because it is not visible. Further, in the third region 3, light is shielded near the boundary with the first region 1 because the total light transmittance of the second decorative layer 10 is low, and as the distance from the vicinity of the boundary with the first region 1 increases. Since the total light transmittance of the second decorative layer 10 is increased, the luminance of light passing through the third decorative layer 11 is increased. Since the third decorative layer 11 is translucent and the transparent decorative layer 12 is transmissive, the light incident on the third decorative layer 11 from the second decorative layer 10 is the third decorative layer. It permeates through the layer 11 and the transparent decorative layer 12 and is visually recognized by an observer. On the other hand, when the light source 19 is not lit, there is no gradation change in the color of the third region 3, so that a change in design can be made due to the difference between the light source lit and unlit.
Therefore, when the light source 19 is turned on, in the first region 1, indirect light such as a border between the second region 2 and the third region 3 is recognized, so that a stereoscopic effect is generated in the first region 1. The component of indirect light can be strengthened by providing the support 4 with diffusibility or providing a layer that scatters and reflects light inside the support 4 and the light shielding layer. At the same time, the third region 3 can express the difference in gradation change between lighting and non-lighting of the light source 19.

Because it is not visible. Further, in the third region 3, light is shielded near the boundary with the first region 1 because the total light transmittance of the second decorative layer 10 is low, and as the distance from the vicinity of the boundary with the first region 1 increases. Since the total light transmittance of the second decorative layer 10 is increased, the luminance of light passing through the third decorative layer 11 is increased.

The first reflective layer 7 of white ink is provided in the first region 1 on the other surface side of the support 4, and the first light-shielding layer 8 of black ink is laminated on the first reflective layer 7. After the first light-shielding layer 8 is disposed, a light-transmitting colored layer 9 of blue ink is provided in the first region 1, the second region 2, and the third region 3.
Then, a 1,000 cd / m 2 LED light source serving as the light source 19 was placed on the other surface side of the information display panel 20 of the present invention, and an observer 21 on one surface side looked at the time of non-lighting and lighting.

  In Table 1, the thickness d of the support 4 is 1 mm, the width w3 of the narrowest portion of the third region 3 is 20 mm, the width w1 of the widest portion of the first region 1 and the second The calculation result of w2 / w1 when the width w2 of the narrowest part of the region 2 is changed, the color when the light source 19 is not lit, the color in the first region 1 when lit, the first region 1 and the second region The stereoscopic effect of the boundary part with the area | region 2 is shown.

  In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

  From Table 1, since the blue color is visually recognized when the light source 19 is turned on in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, the color change can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w2 / w1 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of the light that is diffusely reflected by the second reflective layer 5 and goes toward the first region 1 is lowered.

  In Table 2, the thickness d of the support 4 is 1 mm, the width w2 of the narrowest portion of the second region 2 is 20 mm, and the width w1 and the third width of the widest portion of the first region 1 are shown in Table 2.

  From Table 2, blue is visually recognized when the light source 19 is lit in each condition in the first region 1 and is different from white when the light source 19 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that w3 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w3 / w1 is less than 0.15, the third region 3 is narrow, so that it is presumed that the luminance of the light that is diffusely reflected by the second reflective layer 5 and goes toward the first region 1 becomes low.

  In the configuration of FIG. 1, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2 and the width w3 of the narrowest portion of the third region 3 in the configuration of FIG.

Note that d is in the range of 0.10 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 3, since the blue color is visually recognized when the light source 19 is lit in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, the color change can be expressed by the lighting and non-lighting of the light source 19. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. When d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 5 spreads on the support 4 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

Note that d is in the range of 0.10 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 4, when the light source 19 is turned on in each condition in the first region 1, blue is visually recognized and is different from white when the light source 19 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w3 needs to be 1.00 or more. When d × w3 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 5 spreads on the support 4 in the third region 3 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

  In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

  From Table 5, in the first region 1, when the light source 19 is turned on under each condition, blue is visually recognized and is different from the white color when the light source 19 is not turned on. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w2 / w1 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of the light that is diffusely reflected by the second reflective layer 5 and goes toward the first region 1 is lowered.

  2, the thickness d of the support 4 is 1 mm, the width w2 of the narrowest portion of the second region 2 is 20 mm, the width w1 of the widest portion of the first region 1 and the third width The calculation result of w3 / w1 when the width w3 of the narrowest part of the region 3 is changed, the color when the light source 19 is not lit, the color in the first region 1 when lit, the first region 1 and the third region The stereoscopic effect of the boundary part of the area 3 is shown.

  From Table 6, since the blue color is visually recognized when the light source 19 is lit in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, the color change can be expressed by the lighting and non-lighting of the light source 19. I understand that. Further, it can be confirmed that w3 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w3 / w1 is less than 0.15, the third region 3 is narrow, so that it is presumed that the luminance of the light that is diffusely reflected by the second reflective layer 5 and goes toward the first region 1 becomes low.

  In the configuration shown in FIG. 2, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, and the width w3 of the narrowest portion of the third region 3 are as follows.

Note that d is in the range of 0.10 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 7, since the blue color is visually recognized when the light source 19 is lit in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, the color change can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. When d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 5 spreads on the support 4 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

  In the configuration shown in FIG. 2, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2 and the width w3 of the narrowest portion of the third region 3 in the configuration of FIG. When / w1 is 1 and w3 / w1 is 1, the calculated value of d × w3 when the thicknesses d and w3 of the support 4 are changed, the color when the light source 19 is not lit, and when the light is lit The color in the 1st area | region 1 and the three-dimensional effect of the boundary part of the 1st area | region 1 and the 3rd area | region 3 are shown. Note that d is in the range of 0.10 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 8, since the blue color is visually recognized when the light source 19 is turned on in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, the color change can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w3 needs to be 1.00 or more. When d × w3 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 5 spreads on the support 4 in the third region 3 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

  Tables 1 to 4 of Example 1 and Tables 5 to 8 of Example 2 corresponding thereto correspond to the same results. This is because the light-transmissive colored layer 9 is laminated after the first light-shielding layer 8 as shown in FIG. 1 or after the first reflective layer 7 as shown in FIG. It is considered that the effect is the same because it is arranged in the opening of 8.

A third embodiment of the present invention will be specifically described along the configuration of FIG.
A second reflective layer 5 of white ink is provided on the second surface 2 and the third region 3 by screen printing on one surface side of a polycarbonate having a thickness d as a support 4, and the first additive of black ink is provided. The decorative layer 6 is laminated on the second reflective layer 5 in the second region, the second decorative layer 10 of black ink is disposed on the second reflective layer 5 in the third region 3, and is semi-transmissive A third decorative layer 11 made of a conductive silver ink is laminated on the second decorative layer 10, and a transparent decorative layer 12 having a spin pattern formed of transparent ink is formed on the third decorative layer 11. Laminated and a fourth decorative layer 13 of black ink is provided on part of the support 4 in the first region 1. The second decorative layer 10 sets the total light transmittance near the boundary between the third region 3 and the first region 1 to 0%, and the total light transmittance gradually increases as the distance from the first region 1 increases. The highest part is increased to 90%.
The first reflective layer 7 of white ink is provided in the first region 1 on the other surface side of the support 4, and the first light-shielding layer 8 of black ink is laminated on the first reflective layer 7. After the first light-shielding layer 8 is disposed, a light-transmitting colored layer 9 of blue ink is provided in the first region 1, the second region 2, and the third region 3.
Then, a 1,000 cd / m 2 LED light source serving as the light source 19 was placed on the other surface side of the information display panel 20 of the present invention, and an observer 21 on one surface side observed it.

  In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

  From Table 9, since the blue color is visually recognized when the light source 19 is lit in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, the color change can be expressed by the lighting and non-lighting of the light source 19. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w2 / w1 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of the light that is diffusely reflected by the second reflective layer 5 and goes toward the first region 1 is lowered.

  From Table 10, when the light source 19 is turned on in each condition in the first region 1, blue is visually recognized and is different from the white color when the light source 19 is not lit. Therefore, the color change can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that w3 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w3 / w1 is less than 0.15, the third region 3 is narrow, so that it is presumed that the luminance of the light that is diffusely reflected by the second reflective layer 5 and goes toward the first region 1 becomes low.

  In the configuration shown in FIG. 3, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, and the width w3 of the narrowest portion of the third region 3 are When / w1 is 1 and w3 / w1 is 1, the calculated value of d × w2 when the thickness d and w2 of the support 4 are changed, the color when the light source 19 is not lit, and the lighting time The color in the 1st area | region 1 and the three-dimensional effect of the boundary part of the 1st area | region 1 and the 2nd area | region 2 are shown. Note that d is in the range of 0.10 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 11, since the blue color is visually recognized when the light source 19 is turned on in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, a change in color can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. When d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 5 spreads on the support 4 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

Note that d is in the range of 0.10 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 12, since the blue color is visually recognized when the light source 19 is turned on in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, a change in color can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w3 needs to be 1.00 or more. When d × w3 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 5 spreads on the support 4 in the third region 3 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

  Tables 1 to 4 of Example 1 and Tables 9 to 12 of Example 3 corresponding thereto correspond to the same results. This is because the total light transmittance near the boundary between the third region 3 and the first region 1 of the second decorative layer 10 in Example 3 is 0%, so that the portion is completely shielded from light. This is because a difference in brightness with the region 1 is the same as that in the first embodiment, resulting in a stereoscopic effect. Furthermore, in Example 3, since the total light transmittance increases with increasing distance from the vicinity of the boundary between the third region 3 and the first region 1 of the second decorative layer 10, the transparent decorative layer in the third region 3. Since the direct light transmitted through 12 is visually recognized, the design property is improved as compared with the first embodiment.

A third embodiment of the present invention will be specifically described along the configuration of FIG.
A second reflective layer 5 of white ink is provided on the second surface 2 and the third region 3 by screen printing on one surface side of a polycarbonate having a thickness d as a support 4, and the first additive of black ink is provided.

The second decorative layer 10 sets the total light transmittance near the boundary between the third region 3 and the first region 1 to 0%, and the total light transmittance gradually increases as the distance from the first region 1 increases. The highest part is increased to 90%.

Therefore, the color change can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w2 / w1 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of the light that is diffusely reflected by the second reflective layer 5 and goes toward the first region 1 is lowered.

  In Table 14, the thickness d of the support 4 is set to 1 mm, the width w2 of the narrowest portion of the second region 2 is set to 20 mm, and the width w1 and the third width of the widest portion of the first region 1 are shown in Table 14.

  From Table 14, since the blue color is visually recognized when the light source 19 is turned on in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, a change in color can be expressed by turning on and off the light source 19. I understand that. Further, it can be confirmed that w3 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w3 / w1 is less than 0.15, the third region 3 is narrow, so that it is presumed that the luminance of the light that is diffusely reflected by the second reflective layer 5 and goes toward the first region 1 becomes low.

  In the configuration shown in FIG. 4, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2 and the width w3 of the narrowest portion of the third region 3 in the configuration of FIG.

Note that d is in the range of 0.10 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

  From Table 15, since the blue color is visually recognized when the light source 19 is turned on in each condition in the first region 1 and is different from the white color when the light source 19 is not lit, the color change can be expressed by turning on and off the light source 19.
