[0002]

2. Description of the Related Art In general, a translucent display body in which a predetermined operation display is represented by characters, symbols, figures, or the like is provided in an electric operation unit of an automobile or a switch unit of an electric product. A translucent display of this type is provided with predetermined characters, symbols, figures, etc. (for example, “FM / A”) on a translucent substrate made of a resin molded product or the like.
"M" or "ON / OFF", and characters and figures can be displayed even in a dark place by illuminating from the back side of the base material. In addition, such a translucent display body is designed so that a paint of a color corresponding to the periphery of a device or a switch to be attached is applied to the surface of the base material. An overcoat layer is formed with a highly light-shielding paint on the surface of a base material such as a transparent plate with high transparency so that characters and figures can be visually recognized. I have to do it.

With reference to FIG. 9, a conventional colored translucent display of this type will be described. FIG. 9 is a schematic cross-sectional view schematically showing a conventional general colored translucent display. As shown in the figure, a conventional colored translucent display is provided on a surface of a base material 102 made of a transparent or translucent (colored) resin molded product.
An undercoat layer 103 is formed by applying a translucent paint (for example, a white paint), and an overcoat layer 105 made of a highly light-shielding paint (for example, a black paint) is applied to the surface of the undercoat layer 103. . Then, the base material 102
By irradiating the overcoat layer 105 with laser light, pattern holes 106 representing desired characters, figures, symbols, etc., such as “FM / AM”, are carved.

A conventional colored translucent display having such a structure is illuminated by a light source (not shown) disposed on the back side of the substrate (the lower side in the drawing), so that light is transmitted. Through the light-transmitting base material 102, the undercoat layer 103, and the pattern holes 106, characters and figures can be displayed and viewed even in a dark place. At this time, the surface of the undercoat layer 103 is coated with the overcoat layer 105 having a high light-shielding property, and the light of the light source is shielded in portions other than the pattern holes 106, so that predetermined characters, figures, and the like are vivid in a dark place. Is displayed.

Further, in the daytime or in a bright place, the undercoat layer 103 of the light-transmitting color is exposed through the pattern holes 106, so that the operation display is performed by the contrast between the light-shielding color of the overcoat layer 105 and the light-transmitting color of the undercoat layer 103. Characters, figures, and the like representing are clearly visible. For example, Japanese Patent Application Laid-Open No.
There is a "method of manufacturing a display component" described in JP-A-60761.

[0006] Recently, the designs of electric products and interiors of automobiles have been diversified, and various colors have been applied to various products. There is a growing demand for color variations. For this reason, the colored translucent display body provided in the operation display unit of an electric product or an automobile, etc., particularly, for the overcoat layer applied to the base material surface,
In addition to the conventional black type having a high light-shielding property, it was necessary to provide a wide variety of color variations such as a color with a low light-shielding property such as a silver type. Therefore, a colored translucent display member has been proposed which attempts to meet various needs for colors by applying a non-black paint such as a paint having a low light-shielding property to a base material surface.

FIG. 10 is a schematic cross-sectional view schematically showing a colored translucent display body when a paint having low light-shielding properties is used on the surface of a base material. As shown in FIG.
On the surface of the base material 102, an undercoat layer 103 having a light-transmitting property is formed, and on the surface of the undercoat layer 103, an intermediate coat layer 104 made of a highly light-shielding paint is applied.
An overcoat layer 105 having a high light-transmitting property and a low light-shielding property is applied on the intermediate coat layer 104. Then, the upper coating layer 105 and the intermediate coating layer 104 are integrally removed by using a laser beam or the like, so that pattern holes 106 representing desired characters, figures, and the like are carved.

In the colored translucent display having such a structure, the light illuminated from the back surface of the base material transmits the translucent base material 102.
In addition, the light can be visually recognized through the pattern holes 106 which penetrate through the undercoat layer 103 and the overcoat layer 105 and the intermediate coat layer 104, and characters and figures can be visually recognized even in a dark place. Further, since the intermediate coating layer 104 having a high light-shielding property is formed below the overcoat layer 105, even if a highly translucent paint is used for the overcoat layer 105, the light of the light source can be transmitted through the pattern holes 106.
The overcoat layer 105 can be formed using any paint without leaking from other parts, thereby meeting the needs of a wide variety of colors.

[0009]

However, in such a colored translucent display element in which only a highly transmissive overcoat layer is applied to the surface of the base material, the undercoat visible through the pattern coat and the overcoat layer are provided. Layer and a similar translucent paint (for example,
When the undercoat layer is a white paint and the overcoat layer is a silver paint), the boundary between the overcoat layer and the undercoat layer, that is, the pattern holes representing characters or the like may be difficult to visually recognize. For this reason, especially in the daytime or in a bright place, there is no distinction between the translucent undercoat layer exposed through the pattern holes and the translucent overcoat layer located around the undercoat layer.
In some cases, figures and the like could not be clearly read, and depending on the reflection of light and the viewing angle, they could not be seen at all.

The present invention has been proposed in order to solve the problems of the prior art. The overcoat layer and the intermediate coat layer are removed to form an overcoat along the contour of the pattern hole formed. By removing only the layer and forming the contour hole, the middle coat layer having a high light-shielding property is exposed to the contour shape of the pattern hole, so that characters, figures, etc. can be vivid even in the daytime or in a bright place not illuminated by the light source. In particular, it is an object of the present invention to provide a colored translucent display body suitable for operation display of an electric operation section of an automobile or a switch section of an electric product, and a method of manufacturing the same.

[0011]

According to a first aspect of the present invention, there is provided a colored translucent display, comprising: a base having a light-transmitting property; and a base having a light-shielding property applied on the base. A coating layer, an overcoat layer applied on the intermediate coating layer, a pattern hole for exposing the base formed by removing the intermediate coating layer and the overcoat layer, and along the contour of the pattern hole. A contour hole formed by removing only the top coat layer, and exposing the middle coat layer, wherein the middle coat layer is visible along the contour of the pattern hole from the surface side of the top coat layer. There is a simple configuration. In particular, in claim 2, the base is configured to include a light-transmitting base material and a light-transmitting undercoat layer applied on the base material.

Further, the colored translucent display according to claim 3 is
The pattern hole and the contour hole are formed with steps.

On the other hand, the colored translucent display according to claim 4 is
The pattern holes and the contour holes are formed in an inclined shape such that the pattern holes and the contour holes are wide on the overcoat layer side and narrow on the intermediate coat layer side.

According to the colored translucent display of the present invention having such a configuration, the intermediate coating layer is exposed along the outline of the pattern hole through the outline hole. Characters, figures, and the like represented by the pattern holes and the contour holes are clearly displayed and can be clearly recognized from the outside.

That is, an intermediate coating layer having a high light-shielding property is exposed in a contour shape of a character or the like around a base made of a base material or an undercoat layer having high translucency exposed by the pattern holes. Depending on the contrast of the coloring of the layer, predetermined characters and the like clearly appear, and the characters and the like can be clearly read and visually recognized even in a bright place. As a result, even when the overcoat layer and the base are colored in the same type of translucent color, the contour of the pattern hole is clearly displayed by the exposed portion of the high light-shielding middle coat layer, and the operation can be performed even in the daytime or a bright place. Characters and figures for display can be clearly read and visually recognized.

Claim 5 is claim 1, claim 2 or claim 3.
The method for producing a colored translucent display body according to claim 1, wherein a pattern hole that exposes the base is formed by simultaneously removing the intermediate coating layer and the overcoat layer from the base coated with the intermediate coating layer and the overcoat layer. A step of forming a contour hole exposing the intermediate coating layer along the contour of the pattern hole by removing only the overcoat layer along the contour of the pattern hole. .

According to the method for manufacturing a colored translucent display of the present invention having such steps, pattern holes and contour holes can be sequentially formed by means such as irradiation with a laser beam. The colored translucent display according to the present invention can be reliably implemented. In addition, since the laser beam has a property that the first initial pulse (giant pulse) before entering the continuous irradiation state is very strong, in order to easily and surely expose the intermediate coating layer inside the contour hole, It is preferable that a pattern hole is formed first, and then a contour hole is formed in an outer peripheral portion of the pattern hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. First Embodiment First, a first embodiment of a colored translucent display of the present invention will be described with reference to FIGS. FIG.
4 to 4 are schematic explanatory views schematically showing the colored translucent display element according to the first embodiment of the present invention, in which (a) is a plan view and (b) an enlarged main part along line XX. It is sectional drawing. 5A and 5B are schematic plan views illustrating a method for manufacturing a colored translucent display according to the present embodiment, in which FIG. 5A illustrates a step of forming pattern holes in an overcoat layer and an intermediate coating layer, and FIG. Forming a contour hole in the overcoat layer along the contour of
(C) shows the completed state. FIG.
7A and 7B are schematic plan views illustrating another method of manufacturing the colored translucent display according to the embodiment, in which FIG. 7A illustrates a step of forming an outline hole in an overcoat layer, and FIG. And (c) shows a completed state.

In this embodiment shown in these figures, a pattern such as a predetermined character, symbol or figure is engraved on a translucent base 1 and illuminated from the back side of the base 1 in a dark place. Is a colored light-transmitting display that can display characters, graphics, and the like and is mainly used for operation display of an electric operation unit of an automobile or a switch unit of an electric product. As shown in FIG. 1, a colored translucent display according to the present embodiment includes a base 1 having a light-transmitting base material 2, an undercoat layer 3 applied to the base material 2, and an undercoat layer 3 on the base 1. And an overcoat layer 5 applied on the middle coat layer 4. It has a pattern hole 6 formed by removing the middle coat layer 4 and the top coat layer 5, and a contour hole 7 formed by removing the top coat layer 2 along the contour of the pattern hole 6.

The base material 2 constituting the base 1 is a light-transmissive plate-like member made of, for example, a transparent or colored translucent resin molded product or the like, and is schematically shown in FIGS. Are processed and formed into various shapes according to products, devices, and the like to be attached. A light source (not shown) is provided on the back side (the lower side in the drawing) of the base material 2 to illuminate the base material 2 from the inside of a product or the like.
The shape of a pattern hole 6 to be described later is made to emerge as a character, a figure, or the like.

The undercoat layer 3 constituting the base 1 together with the base material 2 is made of a light-transmitting paint applied on the surface of the base material 2 and is usually a light-transmitting paint such as a white paint or an arbitrary colored paint. Is formed by coating. By transmitting the light of the above-mentioned light source through the undercoat layer 3, predetermined characters, symbols and the like are displayed. Accordingly, the color of the undercoat layer 3 becomes the color of characters, symbols, and the like that appear in a dark place due to the light of the light source.

The undercoat layer 3 can be omitted as appropriate. That is, as described above, the base material 2 can be formed of a translucent colored resin or the like. In such a case, the undercoat layer 3 is omitted as shown in FIG. Thus, the base 1 can be configured. In this case, the light of the light source passes through the substrate 2 to display characters, symbols, and the like, so that the characters, symbols, and the like emerge in a dark place with the color of the substrate 2 made of a colored resin or the like. .

The intermediate coating layer 4 is made of a light-shielding paint applied to the surface of the undercoat layer 3 (the substrate 2 in FIG. 2), and usually a paint having a high light-shielding property such as a black paint is adopted. . The light illuminated from the back surface side of the base material 2 by the intermediate coating layer 4 is shielded at portions other than the portions passing through the pattern holes 6 of the undercoat layer 3, whereby predetermined characters, figures, and the like are darkened. It will be displayed vividly. Then, in the present embodiment, the intermediate coating layer 4 having a high light-shielding property, as described later,
It is exposed along the outer peripheral contour of the pattern hole 6 through the contour hole 7, and the characters displayed by the pattern hole 6 are determined by the exposed portions (the widths m1 and m2 shown in the drawing) of the intermediate coating layer 4. , Figures, etc. are clearly visible.

The overcoat layer 5 is a paint applied to the surface of the intermediate coat layer 4 and constitutes the surface of the base 1. The color of the overcoat layer 5 is the surface color of the colored translucent display. .
The overcoat layer 5 constitutes a part of the surface of a product or device to which the colored translucent display of the present embodiment is attached, an interior part, or the like. An arbitrary paint is used as the overcoat layer 5 in accordance with the color, design, and the like, for example, and a highly translucent paint such as a silver paint can be used.

That is, according to the colored translucent display of the present embodiment, the overcoat layer 5 includes a paint having excellent translucency.
Any paint can be used. In the translucent display of this embodiment, the intermediate coating layer 4 is coated with a highly light-shielding coating under the top coating layer 5, and the coating of the top coating layer 5 can be formed with any paint. The light is also blocked by the intermediate coating layer 4. Then, the intermediate coating layer 4 having a high light-shielding property is exposed along the outline of the pattern hole 6 through the outline hole 7 described later, and the outline of the pattern hole 6 is clearly displayed by contrast with the undercoat layer 3.

Therefore, any paint can be used as the paint for forming the overcoat layer 5 irrespective of the degree of translucency and light-shielding properties, and regardless of the degree of contrast with the undercoat layer 3. Thereby, various colors can be provided according to the product using the colored translucent display of the present embodiment, and it is possible to meet various needs.

The pattern holes 6 are holes formed integrally with the overcoat layer 5 and the intermediate coat layer 4. The undercoat layer 3 is exposed by removing the overcoat layer 5 and the intermediate coat layer 4. ing. The pattern shape of this pattern hole 6 is
Depending on the product to be used, the pattern is formed as a pattern representing desired characters, figures, symbols, etc., such as “FM / AM”. As a method of forming the pattern holes 6, a laser beam is usually applied to the base 1 on which the intermediate coating layer 4 and the upper coating layer 5 are applied, and the base coating layer 5 and the upper coating layer 5 are formed into a desired character, figure, or the like. It is formed by removing the coating film of the intermediate coating layer 4. As shown in FIG. 2, when the base 1 is composed of only the base material 2 from which the undercoat layer 3 is omitted, the intermediate coat layer 4 and the top coat layer 5 applied directly to the base material 2 are removed. Thereby, the base material 2 is exposed to display characters, figures, and the like.

The contour hole 7 is a hole formed in the overcoat layer 5 along the contour of the pattern hole 6 representing a predetermined character, figure, symbol or the like. That is, the contour hole 7 is formed by removing only the overcoat layer 5 along the contour shape of the pattern hole 6, thereby exposing the intermediate coat layer 4 along the contour of the pattern hole 6, as shown in FIGS. The portions (widths m1 and m2) are formed. The contour hole 7 is also formed by irradiating the overcoat layer 5 with a laser beam and removing the coating film of the overcoat layer 5 along the outer shape of the pattern hole 5.

Here, the exposure widths m1 and m2 of the intermediate coating layer 4 exposed by the contour holes 7 can be arbitrarily set according to the size of characters, figures, symbols, etc. displayed in the pattern holes 6. . Generally, as shown in FIG. 1 or FIG.
A contour hole 7 having a similar shape that is slightly larger than the shape of the pattern hole 6 displaying characters, symbols, etc. is formed, and the exposed width m
1 and m2 are set to be the same.
As shown in (1), the exposed widths m1 and m2 can be formed to have different widths depending on the positions around characters, figures, and the like, and the contour holes 7 and the pattern holes 6 can be formed in non-similar shapes. When the pattern holes 6 and the contour holes 7 are formed in non-similar shapes in this manner, it is possible to make the design of characters and the like different between daytime and when displayed in a dark place. Further, as shown in FIG. 4, for example, it is also possible to form the contour holes 7 only on the right and lower sides of characters, symbols, etc. to expose the intermediate coating layer 4 (m1 shown in FIG. 4). Then, a three-dimensional effect can be given to the displayed characters, figures, symbols, and the like.

In this embodiment, the pattern holes 6 and the contour holes 7 are formed with steps as shown in FIGS. By providing a step between the pattern hole 6 and the contour hole 7 as described above, the edge of the contour hole 7 and the edge of the pattern hole 6 are formed substantially at right angles as shown in FIGS. The boundary between the pattern hole 6 and the contour hole 7 is clearly shown, and the shapes of the pattern hole 6 and the contour hole 7 are clearly displayed to the outside, respectively, in combination with the difference in the color tone between the top coat layer 5 and the middle coat layer 4. Can be done.

Also, as described above, the pattern hole 6 and the contour hole 7
According to the structure having a step, the pattern hole 6 (or the contour hole 7) is first formed by using a laser beam, and then the contour hole 7 (or the pattern hole 6) is formed, as described later. Can be adopted, so that the manufacturing process is performed in two stages, but each process can be performed easily and reliably. Thereby, in the colored translucent display according to the present embodiment, the intermediate coating layer 4 is exposed from the surface side of the top coating layer 5 through the outline hole 7, and the intermediate coating layer 4 is formed along the outline of the pattern hole 6. You can see it.

Next, a method for manufacturing the colored translucent display of this embodiment having the above-described configuration will be described with reference to FIG. Although FIG. 5 shows a method of manufacturing the colored translucent display body corresponding to the embodiment of FIG. 1, the embodiment shown in FIGS. 2 to 4 is manufactured by the same method as described below. be able to. First, pattern holes 6 are formed in the base 1 (base material 2 and undercoat layer 3) on which the intermediate coat layer 4 and the overcoat layer 5 are applied. The formation of the pattern holes 6
Overcoat layer 5 applied to substrate 2 using laser light or the like
And the undercoat layer 4 are simultaneously removed, and the undercoat layer 3 is formed by exposing the undercoat layer 3 to desired characters, figures, symbols, and the like (the character “F” in this embodiment) (the state shown in FIG. 5A). ).

Next, a contour hole 7 is formed around the pattern hole 6.
To form The contour hole 7 is formed by removing only the overcoat layer 5 along the contour of the pattern hole 6 (the outer shape of “F”) by using a laser beam or the like having a lower output power than when the pattern hole 6 is formed. Is formed by exposing the intermediate coating layer 4 along the line (FIG. 5B). As a result, as shown in FIG. 5C, the present embodiment is provided with a contour hole 7 in which the intermediate coating layer 4 (portion indicated by a point in FIG. 5C) is exposed around the outer shape of the pattern hole 6. The manufacture of the colored translucent display of the embodiment is completed.

The laser beam for forming the pattern holes 6 and the contour holes 7 has a very strong initial pulse (giant pulse) before entering the continuous irradiation state. For this reason, in order to easily and surely leave the intermediate coating layer 4 inside the contour hole 7, as shown in FIG. The layer 4 is integrally removed to form a pattern hole 6, and thereafter,
More preferably, the procedure is such that only the overcoat layer 5 at the outer peripheral portion of the pattern hole 6 is removed to form the contour hole 7.

However, by adjusting the output of the laser beam, a contour hole 7 having a large outer shape is first formed as shown in FIG. 6, and then a pattern hole 6 is formed along the inside of the contour hole 7. You can also. In this case, first,
With respect to the base material 2 on which the undercoat layer 3, the intermediate coat layer 4 and the overcoat layer 5 are applied, only the overcoat layer 5 is removed into a desired character or the like ("F" in FIG. 6) by using a laser beam. To form a contour hole 7 (the state shown in FIG. 6A). In this state, the intermediate coating layer 4 is exposed in the shape of the letter “F” via the outline hole 7 (portion indicated by a point in FIG. 6A).

Next, a pattern hole 6 is formed along the inside of the contour hole 7. In this case, the intermediate coating layer 4 is removed along the inner periphery of the contour hole 7 by using a laser beam having a higher output than when the contour hole 7 is formed. 6 while exposing the undercoat layer 3 (FIG. 6).
(State shown in (b)). As a result, as shown in FIG. 6C, the intermediate coating layer 4 (FIG.
The colored translucent display body having the pattern holes 6 for exposing the undercoat layer 3 is completed in a form in which the portion shown by (c) is left). As described above, the manufacturing method in which the contour holes 7 are first formed and then the pattern holes 6 are formed is mainly based on the exposure width of the intermediate coating layer 4 (FIG. 1 to FIG. 1) in which the intensity of the giant pulse of the laser beam does not matter. 4 (m1, m2) can be used to set a relatively large value.

According to the colored translucent display of the present embodiment and the method of manufacturing the same, the light source in which the base 1 composed of the base material 2 and the undercoat layer 3 is disposed on the back side (the lower side in the drawing). When illuminated by a light source (not shown), the light transmitted through the light-transmitting base material 2 and the undercoat layer 3 rises along the contour of the pattern hole 6, and characters, figures, and the like are displayed in a dark place. At this time, since the middle coat layer 4 having a high light-shielding property is applied on the upper side of the undercoat layer 3, the light of the light source is shielded in portions other than the pattern holes 6, so that predetermined characters, figures, and the like are dark. It is displayed vividly.

In the daytime or in a bright place, the middle coat layer 4 is exposed along the contour of the pattern hole 6 through the contour hole 7. The characters, figures, and the like represented by the outline holes 7 are clearly displayed, and can be clearly recognized from the outside. That is, the middle coat layer 4 such as a black paint having high light-shielding property is exposed in an outline shape of a character or the like around the undercoat layer 3 such as a white paint having a high translucency exposed by the pattern holes 6. Due to the contrast between the coloring of the intermediate layer 3 and the coloring of the intermediate coating layer 4, predetermined characters and the like emerge vividly,
Even in a bright place, characters and the like can be clearly read and visually recognized.

Thus, even when the overcoat layer 5 and the undercoat layer 3 are coated with the same type of translucent paint (the undercoat layer 3 is a white paint and the overcoat layer 5 is a silver paint), the overcoat layer 5 and the undercoat layer 3 are formed of a black paint or the like. The outline of the pattern hole 6 is clearly displayed by the exposed portion of the coating layer 4, and characters and figures for operation display cannot be read in the daytime or in a bright place as in the conventional case. Nothing disappears.

[Second Embodiment] Next, a second embodiment of the colored translucent display of the present invention will be described with reference to FIG. FIG. 7 is a schematic cross-sectional view schematically showing a colored translucent display according to the second embodiment of the present invention. As shown in the figure, the colored translucent display of the present embodiment is a modified embodiment of the colored translucent display of the first embodiment described above, and has a pattern hole formed with a step in the first embodiment. 6 and the contour hole 7 are formed in an inclined shape without any step. In addition, FIG. 2 shows a modified embodiment of the colored translucent display body corresponding to FIG. 1 in the first embodiment, but the embodiment corresponding to FIGS. No inclined pattern hole 6 and contour hole 7
Can be applied.

As shown in FIG. 7, in this embodiment, the pattern holes 6 and the contour holes 7 formed by engraving characters and figures for operation display remove the overcoat layer 5 and the intermediate coat layer 4. Thus, they are integrally formed. Then, the pattern holes 6 and the contour holes 7 are inclined so as to be wider toward the upper coating layer 5 and narrower toward the intermediate coating layer 4 so that the edge of the intermediate coating layer 4 is exposed along the outline of the pattern hole 6. The hole is integrally formed as a hole.

In this way, the intermediate coating layer 4 can be exposed along the contour shape of the pattern hole 6 while the pattern hole 6 and the contour hole 7 are formed integrally as a hole without any step. 7, widths n1 and n2), as in the first embodiment, even in the daytime or in a bright place, characters and graphics for operation display can be clearly displayed and visually recognized by the exposed portion of the intermediate coating layer 4. Can be. As described above, according to the colored translucent display of the present embodiment, characters and graphics are displayed by the exposed portion of the intermediate coating layer 4 as in the first embodiment, and the pattern holes 6 and the contour holes 7 are formed. Is formed integrally, the manufacturing process of the pattern hole 6 and the contour hole 7 can be made one process, and the manufacturing process can be simplified.

It should be noted that the colored translucent display of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made within the scope of the present invention. In each of the above-described embodiments, the undercoat layer, the intermediate coat layer, and the overcoat layer formed on the base material are each formed as a single layer, but each of these layers may be arbitrarily formed into a plurality of layers. . For example, as shown in FIG.
a, 4b. In this case, by removing the plurality of intermediate coating layers 4a and 4b stepwise along the contours of characters, symbols, etc., the plurality of pattern holes 6a are removed.
Since a and 6b can be formed, a plurality of intermediate coating layers 4a and 4b are exposed along the inside of the contour hole 7, and characters, symbols, and the like displayed by the intermediate coating layer 4 are multicolored. It is possible to do.

As described above, according to the colored translucent display of the present invention and the method of manufacturing the same, only the overcoat layer is formed along the contour of the pattern hole formed by removing the overcoat layer and the intermediate coat layer. Is removed to form a contour hole, so that the intermediate coating layer having a high light-shielding property can be exposed as a contour of the pattern hole. This makes it possible to display characters, figures and the like vividly even in the daytime or in a bright place where illumination of the light source is not required, and is particularly suitable for operation display of an electric operation unit of a car or a switch unit of an electric product. It is.
