  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not construed as being limited thereto, and various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention.

  The color display module 1 of the present embodiment includes a global lens 10, a holder 12 that holds the global lens 10, and a light source unit 13 that is disposed on the bottom surface of the holder 12. The holder 12 of the present embodiment has a cylindrical shape that is open at both ends, and a plurality of partition walls 14 extending in the axial direction are integrally formed therein. Spaces surrounded by adjacent partition walls 14 form through holes 15, respectively. Each through hole 15 is arranged in parallel with the axis.

  A concave portion 16 that accommodates a part of the global lens 10 is provided on one tip side of the holder 12 that is open at both ends. The concave portion 16 is configured by forming one end edge of the partition wall 14 into a shape cut out so as to circumscribe the hemispherical peripheral surface. The inner diameter of the hemispherical recess 16 is larger than the diameter of the global lens 10. A projection 17 that protrudes toward the center of the hemispherical recess 16 is formed at a predetermined position on one end edge of the partition wall 14 that constitutes the inner peripheral surface of the recess 16. The protrusion amount of the protrusion 17 is made equal to the difference in radius between the recess 16 and the global lens 10. And the protrusion 17 is provided in the deepest part of the recessed part 16, and an upper peripheral part. As a result, in a state where the global lens 10 is set in the recess 16, the projection 17 comes into contact with the surface of the global lens 10 to hold the global lens 10. In this held state, the centers of the global lens 10 and the recess 16 coincide with each other, and the surface of the global lens 10 is separated from the inner peripheral surface of the recess 16 by a predetermined distance. Furthermore, the distance between the surface of the global lens 10 and the inner peripheral surface of the concave portion 16 is the same over the entire surface.

  The global lens 10 and the holder 12 may be integrated by fixing the global lens 10 and the protrusion 17 by using an optically transparent adhesive, for example, or by bonding and integrating them. Instead of this, the entire lens 10 may be simply placed in the recess 16. For example, when the whole lens 10 and the holder 12 are integrated by bonding or the like, for example, the color display module 1 can be tilted sideways or faced down. It is good because the degree of freedom increases.

  The upper end opening of the through hole 15 constituted by the plurality of partition walls 14 is covered with a membrane member 18. Specifically, the contact portion between the one end edge of the partition wall 14 and the membrane member 18 is bonded and fixed using an adhesive. The film member 18 may be made of, for example, a material used for a transmission type screen. When light is irradiated from the back side, the light is transmitted through the film member and from the front side, that is, from the outside of the recess 16 and the holder 12. The light becomes visible. Furthermore, in this embodiment, the light irradiated from the back surface side is diffused by the film member 18, and the opening portion of one through hole partitioned by the partition wall 14 emits light as a whole. The portion of the film member 18 corresponding to the portion becomes the light emitting surface, which becomes the color display portion of the present invention.

  The light source unit 13 includes an LED 20 as a light emitter at a predetermined position at the lower end of each through hole 15. The LED 20 is a color LED and emits an arbitrary color. The predetermined position may be, for example, the center of each through hole 15. Furthermore, although not shown, the light source unit 13 includes a control unit that controls light emission of the LED 20, an internal battery that supplies power to the LED 20 and the control unit, and the like.

  The control unit controls so that at least some of the plurality of LEDs 20 emit light with different colors. All the LEDs 20 may emit light with different colors, or some of the LEDs 20 may emit light with the same color, and another LED 20 may emit light with a different color. The light emitted from each LED 20 travels through the through hole 15 and is irradiated on the back surface of the film member 18 provided in the opening at the other end. Thereby, the surface of the film | membrane member 18 shines with the luminescent color of corresponding LED20. Thus, the inner peripheral surface of the recess 16 emits light in the emission color of the corresponding LED 20 in the region facing each through hole 15. That is, the light emission colors of the color display portions corresponding to the through holes 15 arranged at different positions are different colors.

  As described above, the inner peripheral surface of the concave portion 16 emits light in a predetermined color at each different part. The color emitted from each part passes through the global lens 10 as it is, and is emitted from the surface of the global lens 10 in a predetermined direction. At this time, light emitted at different positions is emitted from the global lens 10 in different directions. In other words, the person who viewed the global lens 10 from the outside changes the color display portion that can be seen through the global lens 10 when the viewing direction is changed. For example, when the viewer looks at the global lens 10 from the front, the light emission color of the color display portion near the center of the recess 16 is visually recognized. In addition, when the viewer looks from the oblique direction with respect to the global lens 10, he / she visually recognizes the light emission color of the color display unit on the peripheral side of the recess 16. Thereby, even if it is the same color display module 1, a different color can be visually recognized according to the viewing angle. In addition, in this embodiment, the global lens 10 is used, and the light emitting surface / color display portion is also a hemispherical surface along the surface of the global lens 10, so that the vertical direction from the front of the global lens 10 to the horizontal direction just beside it is. The light emission color of any one or a plurality of color display portions can be visually recognized from any angle direction. In this embodiment, the area where the display color of the color display unit can be visually recognized is a wide range of a hemisphere that is 360 degrees in a horizontal plane parallel to the tip surface of the holder 12 and 180 degrees in a vertical plane with respect to the tip surface. be able to.

  In the example shown in the figure, twelve through holes 15 and twelve color display portions are provided. However, for example, the size of one through hole 15 may be reduced to increase the number of installations. Thus, by increasing the number of installations and relatively reducing the area of the through-hole 15, the unit area of the light emitting surface / color display portion is also reduced. As a result, for example, the emission colors of a plurality of adjacent color display units can be seen. Then, by changing the light emission colors of the plurality of color display portions, a quaint pattern consisting of a plurality of colors, a part or all of a picture / mark, or a part of a character can be shown via one global lens 10. Or all components can be seen. In addition, by reducing the size of each color display portion, the film member 18 disposed on the inner peripheral surface of the recess 16 has a curved display, and by controlling the emission color of the LED 20 that shines on the back side. Various messages can be displayed.

  Further, in the present embodiment, since the global lens 10 is floated and the space between the global lens 10 and the color display portion on the inner peripheral surface of the concave portion 16 is separated, the desired emission color of the color display portion can be visually recognized. It is good because it can show more limited colors. On the other hand, when the global lens 10 and the color display unit are brought into contact with each other, the light emission color of the adjacent color display unit wraps around and an unexpected extra color is seen. In addition to the colors that can be seen, other colors can be seen.

  In the present embodiment, the separation distance is set to a length corresponding to the difference between the radius of the global lens 10 and the radius of the concave portion 16 so that the hemispherical portion of the global lens 10 protrudes out of the holder 12. This is not limited to this, and the distance protruding outside the holder 12 of the global lens 10 may be changed by appropriately changing the length. By changing the distance in this way, the emission angle of the light emitted from the light emitting surface / color display unit from the global lens 10 may be different.

  In the embodiment described above, the global lens 10 is lifted by the protrusion 17 and a space is provided between the inner peripheral surface of the concave portion 16, but the present invention is not limited to this, and the inner peripheral surface of the concave portion 16. An optically transparent adjustment member may be sandwiched between the lens 10 and the global lens 10. If it does in this way, it can fix more firmly and the distance made to separate may be stabilized.

  In the embodiment described above, the LED 20 is a color LED, and the control unit changes and controls the emission color of the color LED. However, the present invention is not limited to this, and an LED that emits a fixed color is appropriately used. You may make it arrange | position to a position.

  The color display module 1 may be configured as a single unit, or a plurality of color display modules 1 may be mounted to form a three-dimensional structure. FIG. 3 shows a preferred embodiment of the three-dimensional structure according to the present invention. FIGS. 3A and 3B show a first embodiment of a three-dimensional structure, in which the above-described color display module 1 is arranged on the six surfaces and the sides of the cubic main body 25. In this example, the plurality of color display modules 1 have the same configuration. That is, the plurality of color display units display the same color at the same location.

  By adopting such a configuration, for example, when viewed from a certain direction as shown in FIG. 3A, each color display module 1 can visually recognize a light emitting state, for example, light blue, and the viewer can recognize from that position. When the direction of the line of sight with respect to each color display module 1 is changed by moving to the right in the figure, it is possible to see the color (for example, yellow) emitted from another color display unit in each color display module 1.

  Further, the shape of the main body to which the plurality of color display modules 1 are attached is not limited to a simple geometric three-dimensional shape such as a cube as described above, and may be various shapes. As an example, as in the second embodiment shown in FIGS. 3C and 3D, the three-dimensional structure is configured by mounting the color display module 1 on the surface of a humanoid main body 26. In this example, the whole body looks green (FIG. 3C) or red depending on the angle viewed by the viewer (FIG. 3D).

  Further, in the example shown in FIG. 3, the entire color looks the same, but the present invention is not limited to this. For example, the light emission color of the color display unit in each color display module 1 is changed for each color display module 1. As a result, different colors are displayed partially.

  Further, when a plurality of color display modules 1 are mounted on the main body like the above-described three-dimensional structure, a power source for emitting LEDs and a control unit for controlling light emission are mounted on the individual color display modules 1. Instead, it may be performed collectively for the plurality of color display modules 1.

  In the above-described embodiment, the color display module and the three-dimensional structure on which the color display module is mounted use a light emitting body such as an LED, and the display color of the color display unit uses a light emission color. However, the present invention is not limited to this. For example, it may be formed by coloring. FIG. 4 shows an embodiment of the color display module 1 using such coloring. In this embodiment, the holder 12 consists of a flat rectangular body, and the hemispherical recessed part 16 is formed in the upper surface. The inner peripheral surface of the recess 16 is colored with a different color depending on the location (see FIG. 4B).

  For example, after the holder 12 having the recess 16 is formed, a predetermined color may be applied to the recess 16. However, the holder 12 and thus the dimensional shape of the recess 16 may be reduced, When the shape becomes complicated, it becomes complicated to apply in a subsequent process, and it becomes difficult to apply a desired color at a desired position. In such a case, for example, a predetermined color may appear at a predetermined position on the surface while manufacturing a holder 12 having a predetermined shape using a 3D printer.

  Also in this embodiment, it is preferable that the global lens 10 is floated with respect to the recess 16 and the surface is separated by a predetermined distance.

  Furthermore, in each of the above-described embodiments, an example in which one global lens is attached to one holder has been described. However, the present invention is not limited to this, and a plurality of global lenses are attached to one holder. May be. For example, as shown in FIG. 5, recesses 16 that are recessed in a number of hemispheres are provided on the surface of a solid body, for example, a spherical body 28, and the entire lens 10 is mounted in the recesses 16. When the inner surfaces of the individual recesses 16 are painted in multiple colors, one of the multiple colors can be seen depending on the viewing angle.

  As described above, even when the display color of the color display unit is fixed by coloring, there is fun that the display content changes depending on the viewing angle, and by appropriately setting the installation position of the color display unit, Even when viewed from the side, a predetermined color can be visually recognized, and the range in which the color changes can be as wide as, for example, nearly 180 degrees. Also, it does not depend on shape or space.

  Furthermore, in this embodiment, a three-dimensional display or a spatial display that changes color depending on the line-of-sight direction can be constructed. As a result, information corresponding to the line of sight and naked-eye virtual reality become possible. For example, it may be installed on the street so that different map contents (related to the traveling direction) are displayed depending on the viewing angle. In addition, it is possible to express new textures in 3D modeling.

  Further, by using a light emitting body such as an LED as a display color, it is possible to provide a navigation three-dimensional structure or a digital signage that presents different moving images depending on the line-of-sight direction.

  As described above, various aspects of the present invention have been described using the embodiments and the modifications. However, these embodiments and descriptions are not intended to limit the scope of the present invention, but for the understanding of the present invention. It is added that it was provided to contribute. The scope of the present invention is not limited to the configurations and manufacturing methods explicitly described in the specification, and includes combinations of various aspects of the present invention disclosed in the present specification. Among the present inventions, the configuration for which a patent is sought is specified in the appended claims. However, the present invention is disclosed in this specification even if the configuration is not specified in the claims. I would like to remind you that there is a possibility of claiming this configuration in the future.
