  2. Description of the Related Art Conventionally, various interior members such as an instrument panel (hereinafter abbreviated as instrument panel) are disposed in a driver's cabin of a vehicle such as an automobile. Such interior members often incorporate a display device that can display a clock, temperature, and other characters, symbols, patterns, figures, bar graphs, and the like. An example of such a display device is described in, for example, Japanese Patent Laid-Open No. 5-293845 (Patent Document 1).

  In general, a display device disposed in a driver's cab of a car is provided with a molded panel having a transparent or translucent display window (translucent portion) and a back side of the display window of the molded panel. And a display for emitting and displaying a pattern or the like. Further, as the display body, for example, a liquid crystal display device (LCD), a light emitting diode (LED), a plasma display device (PDP) or the like is used. Accordingly, a driver or a passenger in a car can visually recognize the light emission display of the display body through the display window provided in the display device, and can acquire various information from the displayed image.

  Patent Document 1 relates to an invention of a molded panel (injection molded product) used for such a display device or the like, and images of indoor lighting fixtures, drivers, etc. are reflected in the display window (translucent portion). In addition, a molded panel is disclosed in which it is difficult to see the light-emitting display of the display body through the light-transmitting portion due to reflection of natural light or light from indoor lighting equipment. Specifically, in the molded panel of Patent Document 1, a translucent thin film layer made of a compound having a refractive index smaller than the refractive index of the translucent part is formed on at least one surface of the translucent part of the molded panel. It is characterized by being. As a result, the molded panel of Patent Document 1 can suppress the reflection of the surface of the light-transmitting part and increase the amount of light transmitted through the light-transmitting part. Become.

  In addition, the display device as described in Patent Document 1 is provided in a driver's cab of an automobile, and displays / hides images such as characters and patterns by turning on and off the display body, for example. It is possible to repeat or change the shape of the image displayed on the display body. As a result, the display device provides various information to the driver and the like by displaying the clock and temperature as described above, and various other warning displays.

  For this reason, the display device has excellent visibility so that the characters, symbols, patterns, etc. displayed by the display device can be clearly and clearly confirmed so that the driver can recognize information reliably. Is required. In addition, since the display device is generally often incorporated in an instrument panel or the like of an automobile, it is desired that the device itself has a high decorativeness and a high-class feeling in the form and display method of the device. However, the display device described in Patent Document 1 has a flat and general image display, lacks decorativeness and unexpectedness, and further improvement in visibility has been desired. Accordingly, in order to appropriately respond to these demands on the display device, innovative design and improvement of the display device are continuously performed even now.

  Incidentally, Japanese Patent No. 3505617 (Patent Document 2) has nothing to do with a display device used in a driver's cab or the like of an automobile. An invention relating to a virtual image display decorative body that makes a virtual image appear below is described. The virtual image display decorative body described in Patent Document 2 is a pixel formed by aligning a plano-convex lens-shaped condensing element layer formed by aligning plano-convex lens-shaped condensing elements, a transparent substrate layer, and pixels. A decorative body in which layers are laminated.

  Further, the position of at least one plano-convex lens-shaped condensing element in the plano-convex lens-shaped condensing element layer and the position of at least one pixel in the pixel layer overlap in the stacking direction. Furthermore, other pixels (pixels located on the same circumference centering on the overlapping pixels) that are equidistant from the overlapping pixels are placed on the plano-convex lens condensing elements corresponding to the respective pixels. On the other hand, they are shifted with the same width radially outward or inward from the overlapping pixels. At the same time, the plano-convex lens-shaped light condensing element and the pixel are arranged so that the distance from the plano-convex lens-shaped light condensing element increases as the pixel moves away from the central pixel.

  The virtual image display decorative body having such a configuration uses the optical illusion of the human to cause an image formed by the pixels of the pixel layer to float and appear as a virtual image in front (upper) of the decorative body. Or it can sink and appear in the back (downward) of the decorative body. Therefore, by using the virtual image appearing decorative body described in Patent Document 2 for a product such as a printed matter, a label, or a toy, it is possible to attract an observer's eyes and make the product interested. Yes.

However, such a virtual image appearing decorative body is to make the pattern formed by the pixels of the pixel layer appear as a virtual image, which appears above or below the actual position. For this reason, the virtual image display decorative body of Patent Document 2 cannot repeatedly display / hide a pattern. For example, a display that displays a clock or the like by changing the shape of an image (virtual image) to be displayed. Not suitable for application to equipment. Therefore, conventionally, it has not been considered to use the virtual image display decorative body of Patent Document 2 for a display device or the like provided in a driving cab of an automobile.

In addition, the dimension ratio of each structural member shown in each drawing is shown in a size different from the actual dimension ratio in order to facilitate understanding of the characteristics of the present invention.

  The light-emitting display device 1 shown in FIG. 1 is disposed at a predetermined position of an instrument panel 2 provided in a driver's cab of an automobile. In addition, as described in detail below, characters such as “ABC” and images (second images) such as symbols, patterns, figures, and bar graphs are raised from the background image (first image). Thus, various information can be provided to the driver and passengers.

  As shown in FIG. 2, the light-emitting display device 1 includes a decorative body 3 that displays a three-dimensional image, and a light source 4 disposed on the back side of the decorative body 3. The light source 4 is supplied with electricity by the light source wiring 5. For example, a voltage of 12 V or 24 V is generally used for a light source used in a display device for an automobile, and a current of 200 to 300 mmA is required. The light source 4 is not particularly limited, and a general light bulb, a cold cathode tube, or the like can be used. In addition, a surface electric field display (SED), a light emitting diode (LED), electroluminescence (EL), plasma display (PDP), field emission display (FED), fluorescent display tube (VFD), or the like can also be used.

  The decorative body 3 includes a decorative body body 10 and a resin base layer 11. The resin base material layer 11 is formed in a predetermined shape by injection molding a transparent or translucent thermoplastic resin, and functions to stabilize the shape of the decorative body 3 and increase the strength. Although the thickness of this resin base material layer 11 is not specifically limited, For example, it is preferable that it is formed with the thickness which can permeate | transmit the light from the light source 4 without greatly attenuating.

  Examples of the material for the resin base layer 11 include acrylic resins such as polymethyl methacrylate resin (PMMA), polystyrene resins (PS), polycarbonate resins (PC), polyarylate resins (PAR), and polysulfone resins (PSU). , Polyethersulfone resin (PES), acrylonitrile-butadiene-styrene copolymer resin (ABS), arton resin, methylpentene polymer, polyamide resin 6 (PA6), polyamide resin 12 (PA12), polyethylene terephthalate resin (PET) Etc. can be used. In particular, in consideration of production costs, it is preferable to use polymethyl methacrylate resin (PMMA) or polycarbonate resin (PC). In addition, the resin base material layer 11 can select the thickness arbitrarily as needed, or the formation itself can also be abbreviate | omitted.

  Further, as shown in FIG. 3, the decorative body main body 10 includes a plano-convex lens-like condensing element layer 12, a protective layer 13, a light-transmitting sheet layer 14, a pixel layer 15, and a light transmitting member. The blocking layer 16 and the adhesive layer 17 are laminated to have a thickness of about 1.0 mm as a whole.

  The plano-convex lens-shaped condensing element layer 12 is located on the outermost surface of the decorative body 3, and a plurality of plano-convex lens-shaped condensing elements 18 having the same shape and size are aligned vertically and horizontally at predetermined regular intervals. Is formed. The plano-convex lens-shaped condensing element layer 12 in which the plurality of plano-convex lens-shaped condensing elements 18 are aligned is formed with a thickness of 50 μm on the surface of the protective layer 13 by, for example, screen printing using a transparent ink or the like. can do.

  The protective layer 13 is an ink layer formed by screen printing in order to protect the light-transmitting sheet layer 14 and the like from the outside and improve chemical resistance, scratch resistance, light resistance and the like. The protective layer 13 is formed with a film thickness of about 5 μm using acrylic ink, urethane ink, UV curable ink, silicon ink, or the like according to the required properties. For example, when the light transmitting sheet layer 14 is protected by the plano-convex lens-shaped condensing element layer 12 and the performance can be sufficiently secured, the formation of the protective layer 13 can be omitted.

  The light transmitting sheet layer 14 is made of a transparent or translucent synthetic resin, and may be colored as long as it has transparency. Specifically, for example, a permeable sheet or film made of an acrylic resin such as polymethyl methacrylate resin (PMMA), polycarbonate resin (PC), polyethylene terephthalate resin (PET), polyethylene resin (PE), polyolefin resin, or the like. Can be used. In particular, in consideration of production costs and the like, it is preferable to use a transmission sheet or a transmission film made of polymethyl methacrylate resin (PMMA) or polycarbonate resin (PC). In addition, the light-transmitting sheet layer 14 can be made of transparent or translucent glass.

  The film thickness of the light transmitting sheet layer 14 is preferably 0.5 mm or more and 3.0 mm or less, particularly 1.0 mm or more and 2.0 mm or less. When the thickness of the light transmissive sheet layer 14 is less than 0.5 mm, as described in detail below, the size shifted downward (or above) the virtual image position of the image formed by the pixels of the pixel layer 15 becomes small. , Can not give enough visual effect. On the other hand, when the film thickness of the light transmission sheet layer 14 exceeds 3.0 mm, light is transmitted through the first image formed by the pixels of the pixel layer 15 and the transmission part 19 of the light transmission / blocking layer 16. The formed second image appears blurred. Moreover, when the light-transmitting sheet layer 14 becomes too thick, there is a problem that it is difficult to process the decorative body 3.

  The pixel layer 15 has a plurality of pixels 9 having the same shape and size corresponding to the plano-convex lens-shaped condensing elements 18 in the plano-convex lens-shaped condensing element layer 12 at predetermined regular intervals. Are aligned with each other. The pixel layer 15 in which the plurality of pixels 9 are formed can be formed with a film thickness of about 5 to 20 μm, preferably about 10 μm, for example, by performing screen printing using colored ink and transparent ink having transparency. it can. Further, the shape of the pixel 9 formed in the pixel layer 15 is not particularly limited, and can be arbitrarily selected from a circular shape, a square shape, a star shape, a heart shape, a character shape, and the like.

  In this embodiment, the position of at least one plano-convex lens-shaped condensing element 18 in the plano-convex lens-shaped condensing element layer 12 and the position of at least one pixel 9 in the pixel layer 15 are overlapped in the stacking direction. It is arranged. At the same time, with the plano-convex lens-shaped condensing element 18 and the pixel 9 arranged at the overlapping position as the center, the positions of the other pixels 9 in the pixel layer 15 are the plano-convex lens-shaped condensing corresponding to the pixel 9. The width of the shift between the pixel 9 and the plano-convex lens-shaped condensing element 18 becomes larger as the pixel is displaced inward in the radial direction with respect to the position of the element 18 and further away from the central pixel. It is configured as follows.

  Since the arrangement of the plano-convex lens-shaped condensing elements 18 of the plano-convex lens-shaped condensing element layer 12 and the arrangement of the pixels of the pixel layer 15 have the relationship as described above, the plano-convex lens-shaped condensing element layer 12 is provided. When the pixel layer 15 is viewed with the naked eye via the protective layer 13 and the light transmission sheet layer 14, the first image formed by the plurality of pixels 9 of the pixel layer 15 due to the optical illusion is a virtual image. Appears below the actual level.

  The light transmitting / blocking layer 16 is disposed on the back surface of the pixel layer 15 with a film thickness of, for example, about 3 to 10 μm, preferably about 5 μm, and the blocking section 20 that blocks the transmitting section 19 that transmits light from the light source 4. And are formed. Further, the light transmitting portion 19 in the light transmitting / blocking layer 16 is formed in a shape such as a character or a pattern to be displayed as information on the decorative body 3. Such a light transmitting / blocking layer 16 can be formed by applying a paint to a predetermined region on the back surface of the pixel layer 15. In addition, for example, a liquid crystal panel is provided on the back surface of the pixel layer 15. It is also possible to configure by.

  Further, an adhesive layer 17 is formed on the back surface of the light transmitting / blocking layer 16 with a film thickness of about 3 to 10 μm, preferably about 5 μm, and adhesion between the decorative body main body 10 and the resin base material layer 11 is achieved. Strength is increased. The material of the adhesive layer 17 is not particularly limited, and for example, an epoxy resin having adhesiveness can be used. In addition, formation of this contact bonding layer 17 can be abbreviate | omitted as needed.

  According to the light emitting display device 1 configured by the decorative body 3 and the light source 4 as described above, the first image formed by the plurality of pixels 9 in the pixel layer 15 is a virtual image and the light transmission / blocking layer 16. Appear below the position of the second image such as a character or pattern formed by transmitting light. As a result, when the decorative body 3 is viewed from the surface side with the naked eye, the second image such as letters and patterns appears as if the second image appears to emerge from the first image in the light transmitting sheet layer 14. Effects can be obtained.

  Thereby, the light-emitting display device 1 can display images such as characters and patterns clearly and clearly, and can improve the visibility. In particular, since the display image looks three-dimensional and the attention of the observer increases, it is very effective when used as a warning display, for example. Furthermore, the visual effect can give an observer a superior decorative property and a high-class feeling. In addition, since the decoration body 3 can change the position where the virtual image of the first image appears by changing the film thickness of the light-transmitting sheet layer 14, as a result, characters and The position where the second image such as a pattern can be seen can also be changed.

  Further, the light emitting display device 1 according to the present embodiment can appropriately display / hide characters and patterns by turning on and off the light source 4 and can arbitrarily display the information regardless of day or night. Can be projected. Furthermore, for example, when the light transmission / blocking layer 16 is formed of a liquid crystal panel as described above, the shape of the second image formed by transmitting light through the transmission portion 19 can be changed as appropriate, so that a watch, It is possible to easily display temperature and other real-time information. Therefore, the light-emitting display device 1 can be used very suitably as a clock display device, a temperature display device, and other display devices incorporated in an instrument panel of a car, for example.

  Furthermore, in the light emitting display device 1 of the present embodiment, the second image is formed as long as the light from the light source 4 passes through the transmission part 19 of the light transmission / blocking layer 16. The position and the like are not particularly limited and can be designed freely. In addition, since the light source 4 is disposed on the back side of the decorative body 3, it is possible to conceal and protect the expensive light source, and as a result, it also protects the driver and passengers. Furthermore, according to the light emitting display device 1 of the present embodiment, due to the lens effect of the plano-convex lens-like light condensing element layer 12 formed on the surface, characters and the like are actually transmitted through the light transmitting / blocking layer 16. A secondary effect of displaying about 10% larger than the size can also be obtained.

  In the present embodiment, as described above, the light-emitting display device 1 in which the second image such as a character or a pattern appears to emerge from the first image by pixels has been described. However, the present invention is not limited to this. For example, the second image such as a character or a pattern may be displayed so as to be depressed more than the first image. For example, in the embodiment, in the relationship between the arrangement of the plano-convex lens-like condensing elements 18 in the plano-convex lens-like condensing element layer 12 and the arrangement of the pixels 9 in the pixel layer 15, the plano-convex lens-like collections disposed at the overlapping positions. Centering on the photoelement 18 and the pixel 9, the positions of the other pixels 9 are shifted toward the “inside” in the radial direction with respect to the position of the plano-convex lens-shaped condensing element 18 corresponding to the pixel 9.

  However, in the relationship between the arrangement of the plano-convex lens condensing elements 18 and the arrangement of the pixels 9, the position of each pixel 9 other than the center is relative to the position of the plano-convex lens condensing element 18 corresponding to the pixel 9. In the case of a light emitting display device that is shifted toward the “outside” in the radial direction, the first image formed by the plurality of pixels 9 of the pixel layer 15 appears above the actual level as a virtual image. For this reason, it can display so that 2nd images, such as a character and a pattern, may sink rather than the 1st image by a pixel. By displaying the second image such as characters and patterns so as to sink more than the first image in this way, it is possible to give a stereoscopic effect (depth feeling) to the second image. It is possible to produce decorativeness and luxury.

  Next, a method for manufacturing the decorative body 3 will be described.
