(First embodiment)
FIG. 1A to FIG. 1C are schematic perspective views illustrating the display device according to the first embodiment.
As illustrated in FIG. 1A to FIG. 1C, the display device 110 according to the present embodiment includes an image forming unit 10 and a driving unit 20. In this example, the display device 110 further includes a housing 40. In this example, the image forming unit 10 and the driving unit 20 are fixed to the housing 40.

  In this example, the display device 110 further includes a fixing unit 41. The fixing unit 41 can fix the housing 40 (that is, the image forming unit 10) to the equipment 220 of the user of the display device 110. In this example, the equipment 220 is a shoe. The fixing portion 41 may be detachable from the housing 40. The fixing of the display device 110 and the equipment 220 by the fixing unit 41 may be releasable.

  The display device 110 is used by being disposed on the display unit 210 (light receiving unit), for example. The display unit 210 is a floor, for example. As will be described later, the display unit 210 may be a wall. The display unit 210 has a surface 210a. When the display unit 210 is a floor, the surface 210a corresponds to the floor surface. The display unit 210 includes a phosphorescent layer as will be described later.

Hereinafter, in order to simplify the description, it is assumed that the surface 210a of the display unit 210 is a flat surface.
A direction perpendicular to the surface 210a of the display unit 210 is defined as a Z-axis direction. One direction perpendicular to the Z-axis direction is taken as an X-axis direction. A direction perpendicular to the X-axis direction and the Z-axis direction is taken as a Y-axis direction. In the present embodiment, the surface 210a of the display unit 210 may be a curved surface. In this case, focusing on a part of the surface 210a, the Z-axis direction, the X-axis direction, and the Y-axis direction can be defined.

  For example, a roller is provided on the bottom surface of the equipment 220 (shoes), and the equipment 220 (shoes) can move along the surface 210 a of the display unit 210. The image forming unit 10 of the display device 110 is fixed to the equipment 220, so that the image forming unit 10 can also move along the surface 210 a of the display unit 210. In this example, the equipment 220 (shoes) moves along the X-axis direction, and accordingly, the image forming unit 10 also moves along the X-axis direction.

  In the present embodiment, the moving direction may be linear or curved. If the movement direction is curvilinear, the movement can be divided into a plurality of short sections. By paying attention to a plurality of short sections, the moving direction can be regarded as a substantially straight line. Below, in order to demonstrate easily, it demonstrates as a case where a movement is a linear movement along an X-axis direction.

  A plurality of lights 15 are emitted from the image forming unit 10. The plurality of lights 15 are applied to the display unit 210. The drive unit 20 changes the brightness of each of the plurality of lights 15 over time. The drive unit 20 can include, for example, a microcomputer and an electric circuit controlled by the microcomputer.

  FIG. 1A shows a state when time t is time t01. FIG. 1B shows a state when the time t is a time t02 after the time t01. FIG. 1C shows a state where the time t is a time t03 after the time t02.

  As shown in FIG. 1A, at time t01, the display unit 210 is irradiated with light 15 having a predetermined pattern.

  As illustrated in FIG. 1B, the equipment 220 (shoes) advances with the passage of time. The pattern of light 15 changes over time. In this example, the pattern of the light 15 is changed so that the character pattern “AB” is applied to the luminous layer of the display unit 210. Thus, the character pattern “AB” (information 240) is displayed on the display unit 210 behind the equipment 220 (shoes).

  As illustrated in FIG. 1C, the equipment 220 (shoes) further advances with the passage of time. Thereby, a character pattern (information 240) of “C” is further displayed behind the equipment 220 (shoes). Thus, the information to be displayed can include character information. The information to be displayed may include a desired pattern such as a pattern. The character pattern formed in the phosphorescent layer attenuates and disappears after a certain time. When the equipment 220 (shoes) passes through the phosphorescent layer while irradiating light again, a character pattern is formed.

FIG. 2 is a block diagram illustrating the display device according to the first embodiment.
As illustrated in FIG. 2, the display device 110 includes a battery 31, a communication unit 32, and a storage unit 33 in addition to the image forming unit 10 and the drive unit 20. The drive unit 20 is, for example, a control unit. For example, a microcomputer may be used as the control unit. The image forming unit 10, the battery 31, the communication unit 32, and the storage unit 33 are connected to the drive unit 20. In this example, a detection unit 36 is further provided, and the detection unit 36 is also connected to the drive unit 20. Hereinafter, examples of the image forming unit 10, the drive unit 20, the battery 31, the communication unit 32, the storage unit 33, and the detection unit 32 will be described.

FIG. 3 is a schematic perspective view illustrating the display device according to the first embodiment.
As shown in FIG. 3, in the display device 110, the image forming unit 10 includes a plurality of light emitting units 11. The plurality of light emitting units 11 are movable along the surface 210 a of the display unit 210. In this example, the number of light emitting portions 11 is eight. The number of the light emission parts 11 is arbitrary. For the light emitting unit 11, for example, a laser or an LED is used. Light 15 is emitted from each of the plurality of light emitting portions 11. The light 15 is light that can be stored in the light storage layer included in the display unit 210. The light 15 may include visible light or may include ultraviolet light. The light 15 may include infrared light.

  When the drive unit 20 moves along the surface 210a of the display unit 210 by temporally changing the brightness of the light 15 emitted from each of the plurality of light emission units 11 as described above, Then, the image forming unit 10 displays information corresponding to the temporal change in the brightness of the light 15 on the phosphorescent layer. That is, the drive unit 20 displays information corresponding to the temporal change in the brightness of the light 15 emitted from the light emitting unit 11 when the plurality of light emitting units 11 move along the surface 210a of the display unit 210. Display on the phosphorescent layer.

  In this example, the display device 110 further includes a substrate 35, a battery 31, a communication unit 32, and a storage unit 33. The battery 31 is, for example, a dry battery or a storage battery. The substrate 35 and the battery 31 are fixed to the housing 40. The plurality of light emitting units 11, the drive unit 20, the communication unit 32, and the storage unit 33 are fixed to the substrate 35. The battery 31 supplies power used by the drive unit 20 and the light emitting unit 11. The communication unit 32 communicates with the outside of the display device 110. The storage unit 33 stores information used for display on the display device 110. The housing 40 includes a cover (not shown) that covers these components.

  The detection unit 36 is a distance measuring device that detects the distance between the plurality of light emitting units 11 and the surface 210a of the display unit 210, for example. The change in distance is one of changes in the relative position between the light emitting part 11 and the surface 210a. The driving unit 20 may change the intensity of the light 15 emitted from the plurality of light emitting units 11 according to the detected distance. Thereby, a character pattern can be clearly displayed regardless of the distance between the light emitting portion 11 and the surface 210a.

  The detection unit 36 may be a speedometer that detects the relative movement speed of the light emitting units 11 relative to the surface 210a along the surface 210a. The moving speed is one of the relative position changes between the light emitting portion 11 and the surface 210a. As will be described later, the drive unit 20 may change the emission timings of the plurality of light emission units 11 in accordance with the detected moving speed.

  For example, the plurality of light emitting units 11 are arranged in the first direction (for example, the Y-axis direction). The image forming unit 10 can move along the second direction (for example, the X-axis direction) as the equipment 220 moves. The second direction is a direction along the surface 210a of the display unit 210 and intersecting the first direction. In the example shown in FIGS. 1A to 1C, the image forming unit 10 moves along the X-axis direction. The image forming unit 10 moves along the second direction intersecting the first direction in which the plurality of light emitting units 11 are arranged, so that the light 15 emitted from the plurality of light emitting units 11 of the image forming unit 10 respectively. Thus, a desired image can be displayed.

FIG. 4A and FIG. 4B are schematic cross-sectional views illustrating the display device according to the first embodiment.
As shown in FIG. 4A, the display device 110 is fixed to the equipment 220 of the user 225. For example, the image forming unit 10 is fixed to the equipment 220 (shoes) of the user 225 by the fixing unit 41. The fixing unit 41 may fix the image forming unit 10 to the body 226 of the user 225 (for example, a thigh or an ankle). For these fixings, for example, a hook-and-loop fastener (pile and hook) can be used.

  In this example, the shoe that is the accessory 220 includes an upper surface portion 221, a bottom surface portion 222, and a roller 223. The upper surface part 221 is a part that covers the legs of the user 225. The bottom surface portion 222 is a portion disposed under the foot. The roller 223 is provided on the bottom surface portion 222, and a part of the roller 223 is exposed below the bottom surface portion 222. Thus, roller shoes are used as the equipment 220.

  The equipment 220 (shoes) can be moved along the surface 210 a of the display unit 210 by the rollers 223. In this example, the equipment 220 is movable along the X-axis direction. The image forming unit 10 fixed to the equipment 220 is also movable along the X-axis direction.

  As illustrated in FIG. 4A, the display unit 210 includes a phosphorescent layer 211. The light storage layer 211 stores light irradiated to the light storage layer 211 for a predetermined time. The phosphorescent layer 211 generates light in accordance with the light irradiated to the phosphorescent layer 211. The phosphorescent layer 211 includes, for example, at least one of zinc sulfide and an aluminate compound (for example, strontium aluminate). For example, the phosphorescent layer 211 can include particles having phosphorescent properties and a coat layer covering the particles. For the coating layer, for example, glass or polymer resin is used. The light storage layer 211 is irradiated with light 15, an excited state is generated by the light 15, and light is emitted from the light storage layer 211. In the light accumulation, light is emitted based on the irradiated light (for example, light 15), and the light is also emitted after the irradiation is completed. The duration of light emission after the irradiation is completed depends on the material used for the phosphorescent layer 211, for example. Phosphorescence includes phosphorescence. When light that can be stored in the phosphorescent layer 211 is irradiated to the phosphorescent layer 211, an excited state is generated in the phosphorescent layer 211, and light based on the light is emitted from the phosphorescent layer 211.

  In this example, the display unit 210 includes a phosphorescent layer 211, an upper plate 212, and a lower plate 213. The phosphorescent layer 211 is disposed between the upper plate 212 and the lower plate 213. The upper plate 212 is light transmissive. For the upper plate 212, for example, a glass plate, an acrylic plate, an epoxy plate, or the like is used. The thickness of the upper plate 212 is, for example, not less than 1 mm and not more than 10 mm. The lower plate 213 may be light transmissive, light shielding, light reflective, or light absorptive. For the lower plate 213, for example, various resins are used. The thickness of the lower plate 213 is, for example, not less than 0.5 mm and not more than 5 mm. The upper plate 212 and the lower plate 213 protect the luminous layer 211. In this example, the upper surface of the upper plate 212 is the surface 210 a of the display unit 210.

  FIG. 4A illustrates the state at the first time t01. FIG. 4B illustrates the state at the second time t02. The second time t02 is a time after the first time t01.

  As illustrated in FIG. 4A, the light 15 is emitted from the plurality of light emitting units 11 at the first time t01. The light 15 has a first pattern 15a. The light 15 is applied to the first position p <b> 1 in the phosphorescent layer 211. At the first position p1, the light 15 of the first pattern 15a is stored.

  As illustrated in FIG. 4B, the light 15 is emitted from the plurality of light emitting units 11 at the second time t02. The light 15 has a second pattern 15b. The light 15 is irradiated to the second position p <b> 2 in the phosphorescent layer 211. At the second position p2, the light 15 of the second pattern 15b is stored.

  The first pattern 15 a and the second pattern 15 b correspond to temporal changes in the brightness of the light 15 emitted from each of the plurality of light emitting units 11. This temporal change is performed by driving the plurality of light emitting units 11 by the driving unit 20.

  A light intensity distribution is formed in the XY plane in the phosphorescent layer 211 by the phosphorescence of the first pattern 15a at the first position p1 and the phosphorescence of the second pattern 15b at the second position p2. This light intensity distribution becomes display information.

FIG. 5A and FIG. 5B are schematic views illustrating the operation of the display device according to the first embodiment.
As shown in FIG. 5A, in this example, first to eighth light emitting elements 11 a to 11 h are provided as the plurality of light emitting portions 11. In this example, one character is displayed with 8 × 8 dots. For example, each of the first to eighth light emitting elements 11a to 11h corresponds to each of eight vertical dots of one character.

Hereinafter, an example of the operation of the plurality of light emitting units 11 when displaying the letter “B” will be described.
As shown in FIG. 5B, at the first time t1, the first to eighth light emitting elements 11a to 11h are turned off. In the off state, the light 15 is not emitted. Alternatively, the intensity of the light 15 in the off state is lower than the intensity of the light 15 in the on state.

  At the second time t2 after the first time t1, the first to seventh light emitting elements 11a to 11g are turned on and the eighth light emitting element 11h is turned off.

  In the third to sixth times t3 to t6 after the second time t2, the first light emitting element 11a, the fourth light emitting element 11d, and the seventh light emitting element 11g are turned on, and the second light emitting element 11b is turned on. The third light emitting element 11c, the fifth light emitting element 11e, the sixth light emitting element 11f, and the eighth light emitting element 11h are turned off.

  At the seventh time t7 after the sixth time t6, the first light emitting element 11a, the fourth light emitting element 11d, the seventh light emitting element 11g, and the eighth light emitting element 11h are turned off, and the second light emitting element is output. The element 11b, the third light emitting element 11c, the fifth light emitting element 11e, and the sixth light emitting element 11f are turned on.

  At the eighth time t8 after the seventh time t7, the first to eighth light emitting elements 11a to 11h are turned off.

  With the above operation, the first to eighth positions arranged along the X-axis direction in the phosphorescent layer 211 are irradiated with the patterns of the light 15 at the first to eighth times t1 to t8. Thereby, the light according to the irradiated light 15 is accumulated at each position in the XY plane, and the letter “B” is displayed by the accumulated light.

  Information including a desired character or graphic pattern can be displayed by changing a temporal change in the pattern of the light 15 emitted from the plurality of light emitting units 11. Information is displayed along the trajectory of movement of the plurality of light emitting units 11 along the surface 210 a of the display unit 210.

FIG. 6A and FIG. 6B are schematic views illustrating the display device according to the first embodiment.
In this example, the display device 110 is fixed to a shoe that is the equipment 220 of the user 225. A roller 223 is provided on the heel portion of the bottom surface portion 222 of the shoe. The roller 223 is not provided on the toe portion of the shoe.

  In the state shown in FIG. 6A, the roller 223 and the bottom surface portion 222 of the toe portion are in contact with the surface 210 a of the display unit 210. As shown in FIG. 6B, when the toe portion is moved upward, the roller 223 rotates, and the shoe can move smoothly along the surface 210a.

  As shown in FIG. 6B, when the toe of the equipment 220 is raised, the light emitting portion 11 approaches the surface 210a, so that the diffusion of the emitted light is suppressed and a clear character pattern can be formed. As shown in FIG. 6A, when the user 225 does not move by the roller 223, the toe of the equipment 220 is lowered and the light emitting part 11 is moved away from the surface 210a. Accordingly, contact between the light emitting portion 11 and the surface 201a can be avoided, and scratches and wear of the light emitting portion 11 can be suppressed.

FIG. 7 is a schematic perspective view illustrating the display device according to the first embodiment.
FIG. 7 illustrates the usage state of the display device 110.
As shown in FIG. 7, the display device 110 is attached to shoes (equipment 220) worn by the user 225. A roller 223 is provided on the bottom surface portion 222 of the shoe, and the shoe can smoothly move on the surface 210 a of the display unit 210. Light 15 emitted from the display device 110 is applied to the phosphorescent layer 211 in the display unit 210, and the light 15 is accumulated in the phosphorescent layer 211, so that information including a desired character can be displayed. Information is displayed for a predetermined time along the trajectory of the plurality of light emitting portions 11.

FIG. 8A and FIG. 8B are schematic views illustrating display by the display device according to the first embodiment.
As shown in FIG. 8A, information including characters including alphabets and numbers can be displayed. As shown in FIG. 8B, information including a pattern of an arbitrary shape can be displayed by the light emission of the image forming unit 10 and the curved movement of the equipment 220. Although FIG. 8A shows an example in which characters are formed by alphabets and numbers, characters and the like may be formed by combinations of various languages, numbers, symbols, and the like.
According to the present embodiment, a display device that presents information by a novel method can be provided.

FIG. 9 is a schematic view illustrating the display device according to the first embodiment.
As shown in FIG. 9, in this embodiment, the image forming unit 10 is attached to the moving body 230. The moving body 230 can be remotely operated. In this example, the moving body 230 can be operated by a wireless or wired system. For example, a radio control car is used as the moving body 230. In this example, the display device 110 is attached to the rear side of the moving body 230 in the traveling direction.

  The moving body 230 moves on the surface 210 a of the display unit 210. Accordingly, a desired display is displayed on the phosphorescent layer 211 for a predetermined time by the light 15 emitted from the plurality of light emitting units 11.

FIG. 10 is a schematic perspective view illustrating the display device according to the first embodiment.
FIG. 10 illustrates another usage state of the display device 110.
As shown in FIG. 10, the display device 110 is attached to the rear side in the traveling direction of the moving body 230 (radio control car). The moving body 230 can move the surface 210a of the display unit 210 smoothly. Also in this case, the light 15 emitted from the display device 110 is applied to the luminous layer 211 in the display unit 210, and the light 15 is accumulated in the luminous layer 211, so that information including a desired character can be displayed.

  In the present embodiment, the display unit 210 may be a wall instead of a floor. For example, when the moving body 230 can move along a wall, a wall, a window, or the like can be used as the display unit 210. Further, a ceiling may be used as the display unit 210. The relationship between the surface 210a of the display unit 210 and the direction of gravity is arbitrary.

  In the display device 110, for example, when the movement speed along the surface 210a of the plurality of light emitting units 11 with respect to the surface 210a is detected, the light is emitted from the plurality of light emitting units 11 according to the detected movement speed. The speed of temporal change of the light 15 may be changed. This makes it easy to maintain a desired display state regardless of the moving speed. The detection unit 36 that detects the moving speed is, for example, a rotational speed meter that measures the rotational speed of the roller, and is attached in the vicinity of the roller shaft. Based on the change in the relative position between the plurality of light emitting units 11 and the surface 210a detected by the detection unit 36, the driving unit 20 determines the intensity of the light 15 and the brightness of the light 15. It is also possible to change at least one of the temporal changes.

  Further, by providing a switch that allows the user 225 to select activation / deactivation of the detection unit 36, a desired display state can be maintained or the display state can be intentionally changed.

  In the display device 110, the image forming unit 10 including the plurality of light emitting units 11 and the driving unit 20 may be provided separately. The image forming unit 10 may be provided in the first casing, and the driving unit 20 may be provided in the second casing. The connection between the image forming unit 10 and the driving unit 20 can be performed by any wired or wireless method.

  Information displayed on the display device 110 may be stored in the storage unit 33 in advance, for example. A storage medium (for example, a USB memory) in which display information is stored in advance may be detachably provided on the housing 40. Information to be displayed may be provided to the display device 110 from a storage unit provided outside the display device 110 via an arbitrary interface. Information displayed on the display device 110 may be supplied via the communication unit 32, for example. For the communication unit 32, for example, any wireless method can be adopted.

  For example, an operation terminal can be connected to the display device 110. For example, information (characters and pictures) is transmitted from the operation terminal to the communication unit 32 of the display device 110 wirelessly.

  The information received by the communication unit 32 is converted into a pattern (text or picture) stored in the storage unit 33, for example. The converted information (electric signal) is supplied to the drive unit 20. Based on the electrical signal supplied from the driving unit 20, light 15 is emitted from the plurality of light emitting units 11.

FIG. 11 is a schematic view illustrating another display device according to the first embodiment.
In this example, the image forming unit 10 includes, for example, a plurality of light sources 51 and a plurality of light guides 52. That is, each of the plurality of light emitting units 11 includes a light source 51 and a light guide 52. Each of the plurality of light guides 52 guides light emitted from the plurality of light sources 51. For the light guide 52, for example, an optical fiber can be used. One end 52 a of the light guide 52 faces the light source 51. The other end 52 b of the light guide 52 corresponds to the light emitting end of the light emitting unit 11. In this example, the other end 52 b of the light guide 52 is fixed to the equipment 220 (shoes) of the user 225 by the light guide fixing portion 53. On the other hand, in this example, the casing 40 is fixed to the leg portion of the user 225 by the fixing portion 41.

  By using the light guide 52, the degree of freedom in designing the display device 110 is expanded. For example, the drive unit 20 and the light source 51 are stored in the housing 40, and the end (the other end 52b) of the light guide 52 connected to the light source 51 is, for example, an accessory 220 (shoes) or a moving body (radio). Control car) or body 226 (ankle, hand, finger) of user 225 may be fixed.

  When the plurality of light guides 52 have flexibility, the relative positions of the end portions of the plurality of light guides 52 may change as the display device 110 moves. That is, the relative positions of the plurality of light emitting portions 11 may change. Thereby, the relative position of the plurality of light emitting units 11 changes due to vibration accompanying the movement of the display device 110, and a pattern reflecting the movement and vibration can be displayed.

  The display device 110 according to the present embodiment can be used for musical and stage performances. The display device 110 can be used to produce a theme park. The display device 110 can be used for effects in events and sales promotions. The display by the display device 110 can include an advertisement, for example. According to the embodiment, more attractive play, performance or installation can be provided.

  Since the display device 110 according to the present embodiment is attached to a side portion other than the lower surface of the equipment 220 or the moving body 230 by the fixing portion 41, the user 225 easily attaches the image forming unit 10 to the equipment 220. And can be attached to and detached from the moving body 230.

  Furthermore, the light guide 52 makes it easy to guide the light 15 to the display unit 210, and the degree of freedom of the mounting position of the display device 110 increases.

  In the present embodiment, even if a large electronic device is not used, a large area can be displayed by making the display unit 210 large. The display unit 210 can perform display without using power. Installation of the display unit 210 is simple.

(Second Embodiment)
