  The present invention combines a visible information display (such as a picture depicting an illustration, a liquid crystal display, an EL display, etc.) with a transparent substrate mounted with an LED element disposed on the front side of the visible information display. The present invention relates to a display device configured such that an LED element of a substrate operates in accordance with visible information of a visible information display body.

  A plurality of displays are arranged side by side in the front-rear direction, and each display has a transparent structure so that the image of the subsequent display is transmitted through the previous display. When viewed from the front, each display has one image. 2. Description of the Related Art Conventionally, display devices configured to be visually recognized as images are known.

  For example, a plurality of thin film EL (electroluminescence) displays are arranged at intervals so as to be overlapped in parallel, and the intervals between the thin film EL displays are determined when the observer views the display image of each display. There is a stereoscopic display device having a transparent structure in which all thin-film EL displays except for the thin-film EL display arranged in the last row are set to be visible with a sense of perspective and transmit visible light. For example, see Patent Document 1).

  In addition, (N + 1) image display plates each having a light emitting element arranged for each pixel are stacked, a light shielding plate is disposed between each image display plate, and each light shielding plate has a light shielding element disposed for each pixel. There is a stereoscopic display device that can be opened and closed for each pixel (see, for example, Patent Document 2).

Japanese Patent Laid-Open No. 7-261677 JP-A-4-291291

  However, since the display device described in Patent Document 1 uses a plurality of EL displays, the cost is very high. In addition, in order for the display image of each EL display to be viewed as a single image from the observer, it is necessary to accurately adjust and control the display operation of the display image of each EL display. It takes time and cost to create software for this purpose. Such a problem becomes more prominent as the number of EL displays used increases.

  Further, in the display device described in Patent Document 2, it is necessary to dispose a light shielding plate in which a light shielding element is disposed for each pixel between image display plates in which light emitting elements are disposed for each pixel. As with the display device, the cost is very high. In addition, it is necessary to accurately control the opening / closing of the light-shielding element according to whether the light-emitting element is turned on or off, and it takes time and cost to create software for that purpose. Such a problem becomes more prominent as the number of image display boards used increases.

  The present invention has been made paying attention to such problems, and an object thereof is to provide a display device capable of three-dimensional display with a sense of depth while having a low cost and a simple structure.

  In order to solve the above-described problems, a display device of the present invention includes a visible information display body, a transparent substrate that is disposed on the front side of the visible information display body and on which an LED element is mounted. The LED element operates according to the visible information of the visible information display body.

  In this display device, the LED element is mounted, for example, at a facing position according to the visible information of the visible information display body. In addition, the luminescent color of an LED element is not specified, What is necessary is just to select suitably the LED element of the luminescent color according to the visible information of a visible information display body.

  Further, the visible information display body displays static visible information. Specific examples thereof include paintings depicting illustrations and the like, designed display objects such as molded articles (including objects having irregularities on the surface), and sculptures and dolls which are solid objects themselves. Alternatively, a static image displayed on a liquid crystal display or an EL display like a photo frame may be used as static visible information instead of a picture or a display object.

  Alternatively, the visible information display body displays dynamic visible information. Specific examples thereof include a liquid crystal display, an EL display, a field emission display, and the like, and an image (moving image) displayed on these displays is used as dynamic visible information. Further, for example, an EL display includes a film-like display that can be bent like a thin film type.

  When the visible information display body displays dynamic visible information, the LED element of the transparent substrate may be interlocked with the operation of the dynamic visible information of the visible information display body.

  Further, the transparent substrate may move relative to the visible information display body in conjunction with the dynamic visible information operation of the visible information display body.

  Alternatively, the visible information display body may be one in which an LED element is mounted on the front surface other than the one that displays the static visible information or the dynamic visible information. In this case, the visible information display body displays visible information by turning on / off the LED element.

  On the other hand, the visible information display body is such that an LED element is mounted on the front surface of the second transparent substrate and a light reflecting plate is provided on the front surface side of the second transparent substrate. The rear surface side of the second transparent substrate is disposed so as to face the transparent substrate, so that the light of the LED element reflected by the light reflecting plate passes through the second transparent substrate itself and reaches the transparent substrate. May be.

  Furthermore, a plurality of transparent substrates may be arranged side by side on the front side of the visible information display body.

  In the present invention, the transparent substrate on which the LED element is mounted is disposed on the front side of the visible information display body. The term “arranged on the front surface side” herein refers to the front side of the visible information display body. This includes not only being arranged at intervals, but also being arranged in close contact with the peripheral surface of the visible information display body. In particular, regarding the latter, when the visible information display body has a more complicated shape (sculpture or doll), if the following PET is used as the material of the transparent substrate, the transparent substrate is made thin and flexible. Since the transparent substrate of PET can be easily deformed, it is easy to place the transparent substrate in close contact with the peripheral surface of the visible information display body.

  Examples of the material of the transparent substrate include PET (polyethylene terephthalate), PC (polycarbonate), and glass, and the properties thereof may be rigid or flexible. In particular, when the transparent transparent substrate is used, the transparent substrate can be bent in accordance with the shape of the visible information display body, and the adaptability to the visible information display body is increased. For example, when the visible information display body is curved in a convex shape on the front side, the transparent substrate can be also curved in a convex shape on the front side accordingly, and the visible information display body is a sculpture or doll In some cases, it is easy to place the transparent substrate in close contact with the surrounding surface.

  According to the first aspect of the present invention, the combination of the visible information display body and the transparent substrate on which the LED elements are mounted enables three-dimensional display with a sense of depth while having a low cost and simple structure. Become. In addition, since the LED element overlaps the visible information on the visible information display body, it feels that the LED element has floated on the visible information due to light emission of the LED element, and various expressions that cannot be realized only with the visible information on the visible information display body Is possible.

  According to the second aspect of the present invention, it is easy to produce an expression by the visible information of the visible information display body and the operation of turning on / off the LED element.

  According to the invention described in claim 3, it is possible to use a picture with illustrations or the like as a visible information display, or a designed display such as a molded product. It is.

  According to the invention described in claim 4, by using a liquid crystal display or an EL display as the visible information display body, various and high-definition expressions are possible.

  According to the fifth aspect of the invention, more varied expressions are possible.

  According to the invention described in claim 6, it is possible to make the expression more varied.

  According to the seventh aspect of the invention, the LED elements of both the visible information display body and the transparent substrate are different from those in the case where the visible information display body is a picture, a display object, a liquid crystal display or an EL display. Can be displayed.

  According to the invention described in claim 8, since the light emitted from the LED elements of the second transparent substrate is reflected by the light reflecting plate and then irradiated to the transparent substrate, the transparent substrate is used when the visible information display body is also used as the light source. The entire surface can be irradiated with light uniformly.

  According to the ninth aspect of the present invention, it is possible to more effectively produce the light depth and stereoscopic effect of the LED elements.

  Hereinafter, the present invention will be described in more detail with reference to embodiments.

  A display device 1A according to the first embodiment is shown in FIGS. The display device 1 </ b> A includes a flat plate-like visible information display body 10 and a flat plate-like transparent substrate 20 disposed on the front side of the visible information display body 10. The distance d between the visible information display 10 and the transparent substrate 20 is about 0 to 50 mm, although it depends on the size. However, in FIG. 2 (the same applies to the other drawings), the distance d between the visible information display body 10 and the transparent substrate 20 is increased for convenience. Of course, the distance d when the transparent substrate 20 is in close contact with the visible information display 10 is 0 mm, and the distance d may be 50 mm or more depending on the size.

  The visible information display body 10 displays static visible information here, and is specifically a painting on which the illustration 11 of Orion is drawn as visible information.

  The transparent substrate 20 is made of the material of the previous example, and a plurality of (here, seven) LED elements 21 are mounted. The seven LED elements 21 are mounted on the transparent substrate 20 at opposite positions (constellation positions) corresponding to the illustration 11 of Orion, and a pattern 22 is provided between the LED elements 21 to indicate the outline of the constellation. ing. This pattern 22 may shine by the light emission of the LED element 21, and can be produced by applying a phosphorescent material, for example. Of course, the LED elements 21 are connected by a desired wiring pattern, and the turning on / off of the LED elements 21 is appropriately controlled according to the illustration 11.

  According to this display device 1A, the LED element 21 of the transparent substrate 20 is present in front of the constellation position in the illustration 11 of the visible information display body 10 that normally does not emit light. For this reason, when the display device 1A is viewed from the front by causing the LED element 21 to emit light, the light of stars appears on the illustration 11 without a sense of incongruity, and a three-dimensional expression that cannot be expressed by the illustration 11 alone becomes possible. . In addition, by using the display device 1A for a gaming machine and blinking the LED element 21, it is possible to achieve effects such as an increase in game expectation.

  A display device 1B according to the second embodiment is shown in FIGS. The display device 1 </ b> B includes a flat plate-like visible information display body 30 and two flat plate-like transparent substrates 40 and 41 arranged on the front side of the visible information display body 30. The distance between the visible information display 30 and the transparent substrates 40 and 41 is the same as described above.

  Here, the visible information display body 30 displays dynamic visible information, and is specifically a liquid crystal display. In this embodiment, the visible information display body 30 displays three types of fireworks images 31, 32, and 33. Images 31 and 32 represent large and small cut fireworks, and image 33 represents a drooping fireworks.

  Both the transparent substrates 40 and 41 have a similar shape as shown in the figure. The transparent substrate 40 is disposed with a space on the front side of the image 31 displayed on the visible information display body 30 and is immovable with respect to the image 31. In the fixed transparent substrate 40, a plurality of LED elements 42 are mounted on two concentric circles so as to match the fireworks shape of the image 31, and a circular pattern 44 is provided between the LED elements 42 on each concentric circle. Yes. Therefore, when viewed from the front side of the transparent substrate 40, each LED element 42 is visually recognized so as to be positioned along the circle of the fireworks display. The LED element 42 is controlled to be turned on / off according to changes in the shape and color of the fireworks from the image 31.

  On the other hand, the transparent substrate 41 is disposed at a distance on the front side of the image 33 displayed on the visible information display 30 and is supported so as to be movable up and down (in the direction of the arrow) while maintaining a certain distance from the image 33. Has been. However, the mechanism for moving the transparent substrate 41 up and down is not specified, and a known mechanism may be used. By this vertical movement mechanism, the transparent substrate 41 appears on the front side of the counter screen of the transparent substrate 41 in the visible information display body 30 at a certain timing, or the image of the counter screen of the transparent substrate 41 in the visible information display body 30 is displayed. The transparent substrate 41 is moved up and down in accordance with the movement.

  A plurality of LED elements 43 are randomly mounted on the movable transparent substrate 41 so as to match the shape of the drooping fireworks in the image 33. Therefore, when viewed from the front side of the transparent substrate 41 when the transparent substrate 41 is in a position facing the image 33, the LED elements 42 are visually recognized as being located in the fireworks. The LED element 43 is controlled to be turned on / off according to a change in the shape and color of the drooping fireworks based on the image 33.

  According to this display device 1B, the LED element 42 emits light in response to the display of the image 31 on the front side of the transparent substrate 40, that is, the light emission (raw light) of the LED element 42 that cannot be expressed only by the image 31 by the liquid crystal display. ) Is added, so it is possible to produce more realistic fireworks expressions.

  In addition, on the front side of the transparent substrate 41, the transparent substrate 41 is controlled to descend gently according to the change of the image 33 and the LED element 43 blinks. It can express how it falls while flashing. In this way, by moving the transparent substrate 41 in accordance with the movement of the image on the opposing screen of the visible information display body 30, the moving luminescent material is lifted and viewed on the opposing screen of the visible information display body 30. Can do.

  A display device 1C according to a third embodiment is shown in FIGS. The display device 1 </ b> C includes a visible information display body 50 that also serves as a surface light source, and a flat transparent substrate 60 that is disposed on the front side of the visible information display body 50. The distance between the visible information display body 50 (transparent substrate 51) and the transparent substrate 60 is the same as described above.

  As shown in FIGS. 6 and 7, the visible information display body 50 includes a transparent substrate (second transparent substrate) 51 and a light reflecting plate 55 attached to the front side of the transparent substrate 51. The transparent substrate 51 is disposed such that the front surface thereof faces the rear side of the display device 1C, and a large number of LED elements 52 are mounted vertically and horizontally on the front surface. The light reflecting plate 55 has a shape as shown in the figure, and diffuses and reflects the light emitted from the LED element 52. The light reflected by the light reflecting plate 55 passes through the transparent substrate 51 itself and reaches the transparent substrate 60 on the front side of the transparent substrate 51.

  The visible information display body 50 also has a function of a surface light source that emits light emitted from the LED element 52 by making the light reflection diffused and reflected by the light reflection plate 55 to make the light emitted uniform. In other words, since the light emission of the LED element is particularly directional, when the light emitted from the LED element is directly applied to the irradiated object, the light emission of the LED element is applied to the irradiated object as the distance between the LED element and the irradiated object is smaller. There arises a problem that irradiation is not uniform. However, in the case of a structure like the visible information display body 50, the light reflection is diffused and reflected by the light reflection plate 55, so that the reflected light reaching the transparent substrate 51 is uniform, and this uniform reflected light is transmitted through the transparent substrate 51. Thus, the transparent substrate 60, which is an object to be irradiated, is irradiated.

  On the other hand, in order to obtain the same light uniformity, when directly irradiating the irradiated object with the light emitted from the LED element, it is necessary to increase the distance between the LED element and the irradiated object. Will become large. However, with a structure like the visible information display body 50, it is possible to reduce the thickness of the light source while obtaining uniform light.

  In such a visible information display body 50, the transparent substrate 51 is arranged with the rear surface side of the transparent substrate 51 facing the transparent substrate 60, so that the light of the LED element 52 reflected by the light reflecting plate 55 is transparent. The light passes through the substrate 51 itself and reaches the transparent substrate 60.

  The visible information displayed by the visible information display body 50 may be expressed by turning on / off a large number of LED elements 52, or a light-transmitting image may be drawn on the front or rear surface of the transparent substrate 51, or Alternatively, a light-transmitting film may be attached, and these images may be irradiated with reflected light from the light reflection plate 55. Alternatively, a light-reflective image is drawn on the light-reflecting surface (inner surface) of the light-reflecting plate 55, or a light-reflective film depicting the image is attached, and these images are irradiated with light from the LED element 52. Also good.

  Although the transparent substrate 60 is not particularly shown in the drawing, a large number of LED elements are mounted, and each LED element is controlled to be turned on / off according to the visible information displayed by the visible information display 50. .

  According to the display device 1C, since the LED elements of the transparent substrate 60 are turned on / off according to the image displayed on the visible information display body 50, when the display device 1C is viewed from the front, the LED elements are displayed on the display image. Images that are turned on and off appear to float, and a three-dimensional expression can be achieved by the images by the visible information display body 50 and the images by the transparent substrate 60.

  In the third embodiment, the light reflecting plate 55 of the visible information display body 50 may be a flat plate in addition to the shape shown in the figure, and the light emission of the LED element 52 is made uniform. Any shape is possible as long as it is possible. The visible information display body 50 includes the transparent substrate 51 and the light reflecting plate 55. As described above, a light reflecting image is drawn on the light reflecting surface of the light reflecting plate 55, or a light reflecting property in which an image is drawn. When the film is attached, the light reflection plate 55 itself can be used as a visible information display body. At this time, the transparent substrate 51 may function as the transparent substrate 60, and the transparent substrate 60 may be omitted.

  A display device 1D according to the fourth embodiment is shown in FIGS. The display device 1D includes a flat plate-like visible information display body 70 and two flat plate-like transparent substrates 80 and 90 arranged side by side on the front side of the visible information display body 70. The visible information display body 70 is larger than the transparent substrate 80, the transparent substrate 80 is larger than the transparent substrate 90, and the transparent substrate 90, the transparent substrate 80, and the visible information display body 70 are juxtaposed in order from the front side of the display device 1D. . The interval between the visible information display body 70 and the transparent substrate 80 and the interval between the transparent substrates 80 and 90 are the same as described above.

  The visible information display body 70 is composed of a transparent substrate 70 on which a large number of LED elements 71 are mounted vertically and horizontally. The transparent substrates 80 and 90 also have a large number of LED elements 81 and 91 mounted vertically and horizontally, respectively. Here, since the sizes of the transparent substrates 80 and 90 are different, part of the light emitted from the LED elements 71 of the visible information display body 70 is transmitted through only the transparent substrate 80, and a part thereof is transmitted through the transparent substrates 80 and 90. The remaining portion does not pass through the transparent substrates 80 and 90 and exits to the front side of the display device 1D. A part of the light emitted from the LED elements 81 of the transparent substrate 80 is transmitted through the transparent substrate 90 and the remaining part is not transmitted through the transparent substrate 90 and is emitted to the front side of the display device 1D. Further, the light emitted from the LED element 91 of the transparent substrate 90 is directly emitted to the front side of the display device 1D. Of course, the LED elements 71, 81, 91 of the transparent substrates 70, 80, 90 are controlled to be turned on / off so as to display a desired image. The visible information display body 70 does not need to be a transparent substrate, and may be a normal opaque substrate.

  According to the display device 1D, since the two transparent substrates 80 and 90 are arranged in front of the visible information display body 70, that is, the LED elements 71, 81 and 91 on three planes whose positions are different in the front-rear direction. Since the light emission overlaps, it is possible to produce a more effective depth and stereoscopic effect of the light (image).

  In the first embodiment, between the visible information display 10 and the transparent substrate 20, in the second embodiment, between the visible information display 30 and the transparent substrates 40 and 41, and in the third embodiment, visible. In the fourth embodiment, a space is provided between the information display body 50 and the transparent substrate 60, and between the visible information display body 70 and the transparent substrate 80, but these transparent substrates are brought into close contact with the visible information display body. You may arrange.

  As described above, since the PET transparent substrate can be easily deformed, when the visible information display body has a complicated shape (sculpture or doll), the PET transparent substrate is in close contact with the peripheral surface of the visible information display body. By arranging them at a minute interval, it is possible to express the visible information display body by light emission from the LED elements of the transparent substrate from all directions of 360 °. Thereby, a new expression that cannot be realized only by a three-dimensional image such as a sculpture or a doll can be realized.
