  However, since the 3D drawing method converts 3D information into 2D information and displays it, there is a problem that the depth cannot be expressed sufficiently. On the other hand, although the method using a three-dimensional screen has better expressive power than the three-dimensional drawing method, it cannot express a depth greater than the thickness of the screen, and still expresses the depth sufficiently. There was a problem that could not.

  The present invention has been made in view of the above problems, and a main object thereof is to provide a three-dimensional information display device and a three-dimensional information display method that are excellent in depth expression.

  In order to achieve the above object, the present invention provides a three-dimensional information display device comprising at least a light emitter in which a plurality of light emitting elements are arranged three-dimensionally and light emission control means for causing each of the light emitting elements to emit light. The light emitting element is composed of a first light emitting element that emits light in a viewpoint direction and a second light emitting element that emits light in a depth direction opposite to the viewpoint direction. Reflecting means is provided on the end face, and the light emitted from the first light emitting element is directly visible, and the light emitted from the second light emitting element is reflected by the reflecting means and visible. Is.

  In the present invention, the light emitter may be configured by laminating a planar light emitter in which a plurality of light emitting elements are two-dimensionally arranged in the depth direction.

  Further, in the present invention, when the viewpoint direction is the positive direction of the Z axis and the Z coordinate of the reflecting means is 0, the positive and negative of the Z coordinate of each point of the display object is determined, and the Z coordinate is When the value is positive, the first light emitting element at the position corresponding to the value is specified, and when the Z coordinate is a negative value, the second light emitting element at the position corresponding to the absolute value of the value is specified. The display control means may be provided, and the light emission control means may cause the first light emitting element or the second light emitting element specified by the display control means to emit light.

  In the present invention, the reflecting means is composed of a plurality of reflecting surfaces having different normal directions, and the light emitted from the second light emitting element is reflected by the plurality of reflecting surfaces in the viewpoint direction. A guided configuration may also be used.

  The present invention also provides a three-dimensional information display method for displaying a display object in a three-dimensional manner by causing each of the light-emitting elements to emit light using a light emitter in which a plurality of light-emitting elements are arranged three-dimensionally. The light emitting element is composed of a first light emitting element that emits light in the viewpoint direction and a second light emitting element that emits light in the depth direction opposite to the viewpoint direction, and the light emitting element in the depth direction By providing a reflecting means on the end face, the light emitted from the first light emitting element can be directly visually recognized, and the light emitted from the second light emitting element is reflected by the reflecting means to be visible. , Representing a depth greater than the thickness of the light emitter.

  In this invention, the said light-emitting body can be set as the structure which laminates | stacks the planar light-emitting body in which the several light emitting element was arranged in two dimensions in the thickness direction.

  Further, in the present invention, when the viewpoint direction is the positive direction of the Z axis and the Z coordinate of the reflecting means is 0, it is determined whether the Z coordinate of each point of the display object is positive or negative, and the Z coordinate Is positive, the first light emitting element at the position corresponding to the value is specified, and when the Z coordinate is negative, the second light emitting element at the position corresponding to the absolute value of the value is specified. The specified first light emitting element or the specified second light emitting element may be configured to emit light.

  Further, in the present invention, the reflecting means is configured by a plurality of reflecting surfaces, and the light emitted from the second light emitting element is reflected by the plurality of reflecting surfaces and guided in the viewpoint direction. It can also be set as the structure which enlarges depth.

  Thus, according to the configuration of the present invention, a three-dimensional shape is expressed by using a light emitter in which a plurality of light emitting elements are arranged three-dimensionally and emitting light corresponding to each point of the display object. Therefore, the depth can be clearly recognized. Further, the plurality of light emitting elements includes a first light emitting element that emits light in the viewpoint direction and a second light emitting element that emits light in the depth direction, and the first light emission is performed based on the coordinates of each point of the display object. Since the element or the second light emitting element emits light, and a reflecting means made of a specular material or the like is provided on the end face in the depth direction of the light emitter, the light from the second light emitting element is reflected, so that the depth is virtually increased. Can be expressed, and the expression power of depth can be enhanced.

  According to the three-dimensional information display device and the three-dimensional information display method of the present invention, the depth of the display object can be sufficiently expressed.

  The reason is that a light emitter in which a plurality of light emitting elements are arranged in three dimensions is formed by laminating planar light emitters in which light emitting elements are arranged two-dimensionally in the depth direction, and the like. The first light-emitting element that emits light in the direction and the second light-emitting element that emits light in the depth direction, and the first light-emitting element or the second light-emitting element emits light based on the coordinates of each point of the display object In addition, since a reflecting means made of a specular material or the like is provided at the end of the light emitting body in the viewing direction and the light from the second light emitting element is reflected by the reflecting means, the depth is more than the thickness of the three-dimensional light emitting body. It is because it can express.

  As a result, space can be used effectively, and even a device that cannot secure a large space can sufficiently express the depth.

  As shown in the prior art, a three-dimensional drawing method is known. However, since this method converts and displays three-dimensional information into two-dimensional information, there is a problem that the depth cannot be expressed sufficiently. there were. In addition, there is a method of actually displaying in three dimensions using a three-dimensional display screen in which a two-dimensional display screen is overlapped in the depth direction, but even this method cannot express a depth greater than the display screen, In order to increase the depth expression, there is a problem that the thickness of the display device itself increases.

  Therefore, in the present invention, a planar light emitter in which light emitting elements are arranged two-dimensionally are stacked in the depth direction to form a light emitter in which a plurality of light emitting elements are arranged three-dimensionally, and a plurality of light emitting elements are arranged. The light emitting element includes a first light emitting element that emits light in the viewpoint direction and a second light emitting element that emits light in the depth direction, and further, reflecting means formed of a mirror material or the like is provided at the end of the light emitter in the depth direction. Then, the coordinates and color information of each part of the display object are given, the first light emitting element or the second light emitting element is caused to emit light according to the coordinates in the depth direction, and the light emitted from the first light emitting element is directly The light emitted from the second light emitting element is reflected by the reflecting means to be visible.

  Thereby, the expression power of the depth is improved without increasing the thickness of the information device itself. Hereinafter, description will be given with reference to the drawings.

  In order to describe the above-described embodiment of the present invention in more detail, a three-dimensional information display apparatus and a three-dimensional information display method according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram illustrating a basic configuration of a three-dimensional information display apparatus according to an embodiment of the present invention, and FIGS. 2 and 3 are diagrams illustrating a structure example of a light-emitting element according to the present embodiment. . FIG. 4 is a diagram schematically showing a display state using the three-dimensional information display device of this embodiment, and FIG. 5 is a flowchart showing a procedure of the three-dimensional information display method of this embodiment. . Moreover, FIG. 6 is a figure which shows typically the other structure of the reflection means of a present Example.

  As shown in FIG. 1, the three-dimensional information display device 100 of this embodiment includes a memory 50 that stores coordinates and color information of each part of a display object, and coordinates and color information from the memory 50 via a data bus 60. CPU 40 for reading, display control means 20 for comparing the coordinates stored in memory 50 with the coordinates of a predetermined reference plane, determining the depth and identifying the light emitting elements corresponding to each part of the display object, and display At least a light emission control unit 30 that controls the light emitting element 11 specified by the control unit 20 to emit light, and a three-dimensional light emitter 10 configured by three-dimensionally arranging the light emitting elements 11 are provided.

  The arrangement of the plurality of light emitting elements 11 constituting the three-dimensional light emitter 10 and the structure of each light emitting element 11 are not particularly limited. For example, as shown in FIG. 2, the plurality of light emitting elements 11 are arranged in the XY direction. The planar light emitters are stacked in the thickness direction (Z direction in the figure) (the number of stacked layers is arbitrary), and the light emission of each light emitting element 11 is controlled by the XY driver 30a and the Z driver 30b. it can.

  Each of the light emitting elements 11 constituting the three-dimensional light emitter 10 includes, for example, an organic EL element (OLED: Organic Light Emitting Diode) that emits red, green, and blue light as shown in FIG. It is possible to adopt a configuration in which light is emitted by applying a voltage from the light emission control means 30 to the electrodes on both sides. In addition, the electrode used for each light emitting element 11 is colorless and transparent, and there is no interference between the light emitting elements 11.

  The light emitting element 11 includes a first light emitting element 11a that emits light in the viewpoint direction (positive direction of the Z axis in FIG. 2) and a second light emitting element that emits light in the depth direction (negative direction of the Z axis in FIG. 2). 11b. The arrangement and structure of the first light emitting element 11a and the second light emitting element 11b are not particularly limited. For example, a configuration in which planar light emitters in which the light emitting elements 11 are arranged in the X and Y directions are coupled in the reverse direction. Alternatively, a planar light emitter in which the first light emitting elements 11a are arranged and a planar light emitter in which the second light emitting elements 11b are arranged may be alternately stacked. it can. Further, the method and structure for defining the light emitting direction of each light emitting element 11 are not particularly limited.

  Further, in the three-dimensional information display apparatus 100 of the present embodiment, as shown in FIG. 4, the reflecting means formed of a mirror material or the like so as to contact the inner part of the light emitter 10, that is, the surface opposite to the viewpoint. 70 is formed.

  Next, the operation of the three-dimensional information display method of the present embodiment will be described in detail with reference to the conceptual diagram of FIG. 4 and the flowchart of FIG. When viewing the three-dimensional information display device from the viewpoint, the horizontal direction is the X axis, the vertical direction is the Y axis, the direction to the reflecting means 70 is the negative direction of the Z axis, and for convenience, the origin of the Z axis is the reflecting means. 70 on the surface.

  First, in step S101, the CPU 40 reads the coordinates and color information of each position of the three-dimensional shape from the memory 50 through the data bus 60, and inputs the coordinates and color information to the display control means 20. To do.

  Next, in step S102, the display control means 20 analyzes the input information and determines whether the Z coordinate of each position of the three-dimensional shape is positive or negative. If the Z coordinate is a positive value, the first light emission is performed. A signal is sent to the light emission control means 30 so as to apply a voltage to the element 11a, and if the Z coordinate is a negative value, a signal is sent to the light emission control means 30 so as to apply a voltage to the second light emitting element 11b.

  If the Z coordinate is a positive value based on the information input from the display control unit 20, the light emission control unit 30 applies a voltage to the first light emitting element 11a at the position corresponding to the value in step S103. , Emit red, green and blue light. Here, when the first light emitting element 11a emits light, the light is emitted in the positive direction of the Z axis, and thus reaches the viewpoint as it is.

  If the Z coordinate is a negative value, in step S104, a voltage is applied to the second light emitting element 11b at a position corresponding to the absolute value of the value to emit red, green, and blue light. Here, when the second light emitting element 11b emits light, the light is emitted in the negative direction of the Z axis, and thus once reflected by the reflecting means 70 and then reaches the viewpoint. Therefore, if the thickness in the Z-axis direction of the three-dimensional information display device is Z1, and the distance in the Z-axis direction from the second light emitting element 11b to the reflecting means 70 is Z2, the reflecting means 70 from the positive surface of the Z-axis. It appears that the second light emitting element 11b reflected in is at a distance of Z1 + Z2.

  In step S105, it is determined whether or not the processing in steps S102 to S104 has been executed for all points of the display target, and the display target is displayed in three dimensions by repeatedly executing the above processing.

  Thus, according to the three-dimensional information display apparatus and the three-dimensional information display method of the present embodiment, when the Z coordinate of the reflecting means 70 is 0 and the viewpoint direction is positive, the Z coordinate of the display object is positive. If the value is a value, the first light emitting element 11a emits light and the light directly reaches the viewpoint. If the Z coordinate is a negative value, the second light emitting element 11b corresponding to the absolute value of the Z coordinate emits light and the light is emitted. Since the light is reflected by the reflecting means 70 and reaches the viewpoint, the depth greater than the thickness of the light emitter 10 can be expressed, and the expression power of the depth can be enhanced.

  In the above embodiment, an organic EL element is taken as an example of the light emitting element 11, but the present invention is not limited to the description of the above embodiment, and any element capable of emitting light using a transparent electrode is used. be able to. In the above embodiment, red, green, and blue light emitting elements are used. However, white light may be passed through red, green, and blue filters to express colors.

  In this embodiment, the depth is expressed by using one reflecting means 70. For example, as shown in FIG. 6, the normal surface of the reflecting surface at the back of the light emitter 10 is inclined with respect to the Z axis. The light reflected by the reflecting surface is reflected by another reflecting surface (the surface in the Z-axis direction in the figure), and the light can be reflected multiple times within the three-dimensional information display device. Thus, by increasing the optical path length, the depth in the Z-axis direction can be further increased.

  The present invention can be applied to any device that is required to display a display object in a three-dimensional manner, and in particular, by being applied to a device that is required to be thin, such as a mobile terminal device such as a mobile phone. A remarkable effect can be obtained.
