Description

  The present invention relates to a high brightness display object in which a character or symbol extraction display portion is formed on a high brightness ground, and a push button switch cover member using the high brightness display object.

  In general, a cover member for a push button switch used for a mobile phone or the like is provided with a large number of key tops, and the key tops may be formed with a display portion for removing characters, symbols, etc. on a colored background. Such a cut-out display portion is highly decorative even if it is as it is, but for example, by illuminating from the back side of the cover member for the pushbutton switch with a backlight or the like, the cut-out display portion is raised and displayed on the front side to display the cut-out display portion further. And functionality can be improved.

  For example, a light-transmitting plastic molded body and a colored light-transmitting coating film and a light-shielding coating film laminated thereon are provided, and the light-shielding coating film is a laser marker. There is known a translucent sign in which a removal display part is formed by partial removal by (Patent Document 1).

The first translucent base material, the first colored layer having the removal display portion, the translucent second colored layer, and the second translucent base material are laminated in this order. An insert sheet for preform is known (Patent Document 2).
Japanese Patent Laid-Open No. 3-116085 JP-A-6-182810

  By the way, there is also known a display body in which a transparent base material is provided with a high brightness, for example, white ground, and a cut-out display part is partially formed. In the case where a translucent extraction display part is provided, it is not preferable that only the extraction display part range having a specific contour shape transmits light and the light is transmitted through a part other than the extraction display part. Therefore, ingenuity has been devised especially for the formation of the white background extraction display portion.

  In the case of a white background display body, a coating film layer or a metal thin film layer containing black carbon or the like is provided in the lower layer of the white background. If a film or metal thin film layer containing carbon or the like is provided below the white background, light that attempts to pass through the film or metal thin film layer containing carbon or the like will be blocked even if the white background is virtually translucent. it can. The extraction display part is formed by irradiation with, for example, a YAG laser. When carbon or metal is irradiated with a YAG laser, it absorbs light energy and disappears. At that time, the carbon or metal brings together the white pigment of the upper layer that has been adhered. When the white pigment disappears together, only the portion irradiated with the YAG laser appears as a display portion.

  When carbon is used as a lower layer and a white background containing a white pigment is formed as an upper layer, the underlying black color can be seen through. This is because a white pigment usually has a low light shielding property. After all, a bright white background is difficult to express, and in the case of a white background design display, there is a drawback that the appearance is changed from the appearance expected at the time of design. When a metal thin film is provided in the lower layer, it is rarely seen through, but the method of providing a metal thin film has a drawback that it is expensive.

  Hereinafter, an embodiment of the present invention will be described.

  FIG. 1 is a cross-sectional view of a key top portion of an illuminated pushbutton switch cover member formed of a white display.

  The illuminated pushbutton switch cover member 1 is usually provided with a number of key tops 2. Such a pushbutton switch cover member 1 is formed of, for example, a laminate sheet 3, the laminate sheet 3 is subjected to, for example, drawing processing, and the key top 2 is provided in a form in which a protruding portion protrudes on the surface side. A transparent hard resin filler 4 is filled on the back side of the protruding portion. In the top surface portion of the key top 2, a cut-out display portion 5 is formed on the laminate sheet 3. On the back side of the extraction display portion 5 of each key top 2, a backlight 6 that is filled with the hard resin filler 4 and further transmits the extraction display portion 5 is disposed.

  The key top 2 is provided with a base sheet 11 having translucency as the laminate sheet 3, and a predetermined uneven shape is imparted thereto by drawing. The base sheet 11 has a range of the cut-out display portion 5 defined on the top surface portion of the key top 2, and a white colored layer 12 corresponding to a high-lightness colored layer is laminated in an area excluding the range of the cut-out display portion 5. Yes.

  A low brightness colored layer 13 is laminated on the back surface of the white colored layer 12. The low-lightness coloring layer 13 has a light-shielding function for shielding the backlight 6 and a back-off prevention function for preventing the light-shielding color of the low-lightness coloring layer 13 from being reflected on the surface, and constitutes a light-shielding / back-lighting prevention layer is doing. The low-lightness colored layer 13 constitutes a show-off prevention layer, and constitutes a gray layer 13a corresponding to the first low-lightness color layer and a light shielding layer, and a black layer 13b corresponding to the second low-lightness color layer. And are included. A gray layer 13a is provided on the back surface of the white colored layer 12, and a black layer 13b is provided on the back surface of the gray layer 13a.

  At the periphery of the blank display portion 5, the outline of the low brightness colored layer 13 is surrounded slightly outside the blank display portion 5. That is, the outline of the gray layer 13a surrounding the blank display portion 5 is slightly outside 0.05 to 0.06 mm from the outline of the white colored layer 12, and the outline of the black layer 13b is the outline of the gray layer 13a. It is further outside.

  The base sheet 11 is formed of a substantially transparent synthetic resin. The base sheet 11 may be a thermoplastic resin or a thermosetting resin as long as it is a transparent synthetic resin. An alloy or a thermoplastic elastomer may be used. Examples of the thermoplastic resin include acrylic resin, polycarbonate resin, PVC resin, ABS resin, PP resin, PS resin, PET resin, ETFE resin, FEP resin, and polycycloolefin resin. Examples of the thermosetting resin include epoxy resin, urethane resin, and silicone rubber. These may be used alone or in combination, and among them, a transparent acrylic resin is most preferable.

  The white colored layer 12 is formed by printing a white ink in which a white pigment is mixed as a filler in a base resin on the back of the base sheet 11. Examples of the base resin include acrylic resin, EVA resin, PVC resin, urethane resin, epoxy resin, polyester resin, and polycarbonate resin. In addition, composite resins containing these resins can be given. Examples of the filler include titanium oxide or other white pigments. Titanium oxide may be rutile or anatase.

  In the white colored layer 12, pearl mica is preferably mixed in at least a part of the filler. The amount of pearl mica used is 2 to 50% by mass, preferably 10 to 40% by mass, and more preferably 15 to 30% by mass in consideration of processing conditions in the whole white ink including the base resin. The particle diameter is preferably 5 to 100 μm. If the amount used is less than 2% by mass, there is a concern that the hiding effect as a sufficient white material may not be sufficient. It is not practical to exceed 50% by mass.

  As a printing method, a method that can accurately form the cut-out display portion is preferably selected. Specifically, for example, screen printing, pad printing, hot stamping, and the like can be given. The thickness of the white colored layer 12 is 5 μm or more, preferably 8 to 50 μm.

  The gray layer 13 a that hits the anti-backing layer is obtained by mixing a filler in the base resin and printing it on the back of the white colored layer 12. Examples of the base resin include the same resins as those that can be used to form the white colored layer 12. For the filler, a white pigment and a black pigment may be used in combination. The white pigment in this case can also be exemplified by the same pigment as the white pigment that can be used for forming the white colored layer 12. Carbon may be used as the black pigment. The mixing ratio of the white pigment and the black pigment is the color sample no. Pantone 7543C (standard of Pantone, France) or better. In the case of Pantone 7544C, there is a concern that the white side of the surface may change due to the back side being seen through from the white background of the surface, including when the thickness of the white colored layer is reduced.

  The gray layer 13a is usually printed by screen printing, for example. The thickness is desirably 8 to 20 μm.

  The black layer 13b constituting the light shielding layer is formed, for example, by printing black polycarbonate ink on the back side of the gray layer 13a.

  In the case of the pushbutton switch cover member 1 described above, the removal display portion 5 is considered to be colorless and transparent, but it is not necessarily limited to being colorless and transparent. Depending on the convenience of the design, colored transparency or colored translucency may be required. In that case, what is necessary is just to use the sheet | seat which mixed the organic pigment or dye of a specific color with transparent resin, and was shape | molded in the film form as the base material sheet 11. FIG.

  The black layer 13b is not always necessary. If light having a relatively low illuminance is used as the backlight, the gray layer 13a alone provides a concealing property for the backlight. In that case, the low-lightness colored layer 13 combining the back-preventing layer and the light-shielding layer may be formed with the gray layer 13a.

  In the case of the pushbutton switch cover member 1 configured as described above, the light inserted from the front side is transmitted through the transparent base sheet 11. In the area other than the blank display portion 5, the inserted light is reflected by the white colored layer 12 and returned. The reflected light is visually recognized as ground color light exhibited by the white colored layer 12. It is not without the light that passes through the white colored layer 12. It reaches the gray layer 13a. The amount of light reaching the gray layer 13a is very small in the total amount. Most of the light reaching the gray layer 13a is reflected by the gray layer 13a without being absorbed. Little light reaches the black layer and is absorbed.

  The light extracted from the front side and inserted into the display unit 5 is absorbed in the direction of the back side of the pushbutton switch cover member 1.

  As described above, the backlight 6 is disposed on the back side of the push button switch cover member 1. Of the light emitted from the backlight 6, the light reaching the extraction display unit 5 passes through the extraction display unit 5 as it is and is visually recognized from the outside. Most of the light reaching the area other than the blank display portion 5 is absorbed by the black layer 13b. The light transmitted through the black layer 13b without being absorbed is absorbed by the gray layer 13a. There is almost no light that passes through the black layer 13b and also through the gray layer 13a.

  Only the light emitted from the backlight 6 is visually recognized in the extraction display unit 5. Only a clear white color is visible in the area other than the blank display portion 5. Thus, a vivid color design is expressed on the push button switch cover member 1. The push button switch cover member 1 configured as described above has a clear white background and excellent decorativeness, and also has excellent keytop visibility during illumination. Further, since the coloring process can be sufficiently performed by the screen printing method instead of the YAG laser, the cost can be suppressed. There is no need to use expensive metal.

  The white colored layer 12 is more preferably a multilayer. FIG. 2 is an example in which a first white layer 12 a corresponding to the first high brightness color layer and a second white layer 12 b corresponding to the second high brightness color layer are provided as the white colored layer 12. The pushbutton switch cover member 1 is shown by the top surface of the key top 2.

  The 1st white layer 12a is formed in the back surface of the base material sheet 11, and the 2nd white layer 12b is provided in the back surface of the 1st white layer 12a. At the periphery of the blank display portion 5, the blank display portion 5 is surrounded, and the outline of the second white layer 12b is slightly outside the outline of the first white layer 12a. The contour line defines the area of the display unit 5 without the outline.

  On the back side of the second white layer 12b, a gray layer 13a corresponding to the anti-backing layer is laminated, and on the back side, a black layer 13b constituting a light shielding layer is laminated.

  The outline of the gray layer 13a surrounds the blank display portion 5, and the outline of the gray layer 13a is outside the outline of the first white layer 12a. However, the outline of the second white layer 12b is further outside, and the outline of the gray layer 13a protrudes inside the outline of the second white layer 12b. Moreover, the black layer 13b is outside the outline of the gray layer 13a.

  Each of the first white layer 12a and the second white layer 12b is formed by mixing a white pigment as a filler in a base resin and printing this on the back of the base sheet. Examples of the base resin that can be used for the base resin of the white colored layer 12 are the same resins as described above. Examples of the filler include titanium oxide and other white pigments. Titanium oxide may be rutile or anatase. In the first white layer 12a, pearl mica is preferably mixed in at least a part of the filler.

  In this embodiment, since pearl mica having excellent light shielding properties is used for the first white layer, the light shielding function can be sufficiently exhibited in the surface layer portion. Pearl mica can be used only on important parts of the design, such as the area around the display area, taking advantage of the advantages and disadvantages of the material. By appropriately combining the first white layer using pearl mica and titanium oxide and the second white layer using titanium oxide, the advantages and disadvantages of both can be complemented appropriately.

  FIG. 3 shows an example of a pushbutton switch cover member 1 in which a key top is formed of a transparent resin plate piece. A transparent resin plate piece forming the key top is used as a base plate 11a, and the key top 2 is configured by the plate piece. The laminate 3 is laminated on the base plate 11a.

  A white colored layer 12 is laminated on the back surface of the base plate 11a. On the back of the white colored layer 12, a gray layer 13a corresponding to the anti-backing layer is laminated, and on the back, a black layer 13b constituting a light shielding layer is laminated. The laminated body 3 formed including the black layer 13b is mounted on the cover member 14 made of silicone rubber via the adhesive layer 15 directly above the pressing protrusion 14a.

  The base plate 11a is made of a material similar to that of the base sheet 11 and is hard. Others are the same as the above example using the base sheet 11. The white colored layer 12 is made of the same material as the white colored layer 12 formed on the base sheet 11. The same applies to the gray layer 13a and the black layer 13b.

  A high brightness display sheet was formed as follows, and the high brightness display sheet was drawn to form a push button switch cover member indicated by the top surface in FIG.

  A transparent polycarbonate film having a thickness of 125 μm was used as the base sheet 11, and white ink was screen-printed on the back side to form the first white layer 12 a. As the white ink, a polycarbonate resin mixed with 20% by mass of pearl mica as a filler was used. On the polycarbonate film 11, the area | region used as the top | upper surface part of the key top 2 was defined, and also the display part 5 was positioned in the top | upper surface part range. The printing of the first white layer 12a was a top surface range and a curved deformation range around the top surface. However, among these, the area range of the blank display portion 5 is excluded from the printing range.

  A second white layer 12b was further printed with white ink on the back of the printed first white layer 12a. For the formation of the second white layer 12a, a white paint using titanium oxide as a filler instead of pearl mica was used. The printing range was the entire surface of the base material sheet 11 on the side where the first white layer was formed, but the blank display portion 5 was excluded from the printing range. Further, a mark was provided at a place where the second white layer 12b should not be formed, and the mark place was also excluded from the printing range.

  At the five peripheral edges of the blank display portion, the blank display portion 5 was surrounded, and the contour line of the second white layer 12b was made to be about 0.15 mm outside the contour line of the first white layer 12a. The thickness of the printing layer was 10 μm.

  The blank display portion 5 was screen-printed with a transparent smoke gray polycarbonate ink to form a colored transparent layer (not shown). The printing range was set to a range of the entire width of the extraction display unit 5 and the width of the outer periphery of 0.4 mm protruding from the extraction display unit 5. The printed layer had a thickness of 10 μm, and the cut-out display part 5 was colored and transparent.

  A gray layer 13a was formed on the back of the second white layer 12b as a back-preventing layer. The gray layer 13a was formed by preparing a gray paint and printing it. The gray paint used was a mixture of a mixture of titanium oxide and carbon mixed with Pantone 7543C and mixed with polycarbonate resin liquid as a filler. The gray layer 13a was printed to a thickness of 15 μm. The printing range was basically the entire range in which the second white layer 12b was formed, and was overlapped with the smoke gray coating area at a width of 0.1 to 0.15 mm at the periphery of the blank display portion 5.

  On the back of the gray layer 13a, a black layer 13a for shielding the backlight was formed. The printing range of the black layer 13a is basically the entire range where the gray layer 13b is formed, and the outline of the printing range is set to the outside by 0.15 mm from the outline of the gray layer 13a at the periphery of the blank display portion. . The thickness of the black layer 13a was 8 μm.

  Thus, the base material sheet 11 on which the black layer 13a was laminated and printed was provided with a key top shape by providing a concavo-convex shape by drawing using a mold. The recess formed by the drawing process was filled with a polycarbonate resin by injection molding and cured to obtain a pushbutton switch cover member 1.

  The cover member 1 for the pushbutton switch thus produced has a bright white appearance with no show-back on the surface of the key top 2, and when the illumination is combined with the backlight, the unplug display 5 has a clear shape. Presented. The push button switch cover member 1 having an excellent appearance was obtained by an inexpensive method called a screen printing method.

  A plate piece having a thickness of 2 mm was injection-molded with a transparent polycarbonate resin, which was used as a key top 2 made of a base plate 11a, and a push button switch cover member 1 as shown in FIG. 3 was formed.

  The range of the blank display portion 5 was determined on the back surface of the key top 2 made of the base plate 11a, and a white colored layer 12, a gray layer 13a, and a black layer 13b were provided to form the laminate 3. The white colored layer 12 used pearl mica as a filler.

  A silicone rubber cover material 14 provided with a pressing portion 14 a was prepared, and the laminate 3 was affixed thereto with an instantaneous adhesive 15. On the silicone rubber cover material 14, a black layer 13b was adhered. In this way, a push button switch cover member 1 was produced.

  In the obtained pushbutton switch cover member 1, the key top 2 made of the base plate 11 a was visually recognized as a display portion 5 having a sense of depth and a clear white region without show-through. When illuminated in combination with a backlight, the undisplayed portion 5 was clearly exposed. The push button switch cover member 1 having an excellent appearance was obtained by an inexpensive method called a screen printing method.
