[0003] [Patent Document 1] JP 2018-024424 A Summary of the Invention [Problem to be solved by the invention]

[0004] A typical display device provides various visual effects by displaying an image, whereas one of the objects of the present invention is to enhance the visual effects provided by the display device.

[0005] The purpose of the present invention is not limited to this, and the applicant intends to obtain rights for configurations that aim to obtain effects from parts of the configurations disclosed in this specification and drawings, etc., by filing a divisional application, amendment, etc. For example, this specification discloses a problem in which the part described as "can be" in this specification is read as "the problem is to be". The problems are described as being independent, and the applicant intends to obtain rights for the configurations for solving each problem separately by filing a divisional application, amendment, etc. Even if the problems are implicitly understood from the description in the specification, the applicant intends to include part of the configurations described in this specification in the scope of the patent claim by amendment or divisional application. In addition, the applicant has disclosed a configuration that solves a problem that combines these independent problems, and intends to obtain rights for it. [Means for solving the problem]

[0006] (1) It is preferable to provide a display device comprising a housing having at least a light-transmitting area facing a first direction, a plate-like member having light-transmitting properties and disposed inside the housing and facing the light-transmitting area, and an image display unit for displaying an image on the plate-like member, wherein the housing has a first region and a second region in a space between the light-transmitting area and the plate-like member, the first region and the second region sandwiching the plate-like member from either side when viewed from the first direction.

[0007] In this way, the image displayed on the plate-shaped member, combined with the first and second regions that exist in the space between the translucent region and the plate-shaped member and sandwich the plate-shaped member from both sides when viewed from the first direction side, can give the user a three-dimensional sense of the image, enhancing the visual effect of the display device.

[0008] (2) The display device may be such that the first region and the second region are inclined in directions away from each other toward the first direction.

[0009] In this way, the image, the first region and the second region which are inclined in directions away from each other in the first direction, in combination, can give the user a three-dimensional impression of the image.

[0010] (3) The housing may be a display device having a third region facing the plate-like member on a second direction side opposite to the first direction.

[0011] In this way, the image displayed on the plate-like member, the first and second regions existing on the first direction side of the plate-like member, and the third region existing on the second direction side of the plate-like member combine to give the user a three-dimensional impression of the image.

[0012] (4) The third region may be a display device having a different color or pattern from the first region and the second region.

[0013] The difference in color or pattern between the first and second regions on the first direction side of the plate-like member and the third region on the second direction side of the plate-like member can enhance the three-dimensional effect of the image.

[0014] (5) The housing may have a fourth region between the first region and the second region, and the fourth region may be a display device that is inclined toward a third direction toward the first direction and away from the plate-like member when viewed from the first direction side.

[0015] In this way, even if the user's line of sight is tilted toward the third direction, the user can easily view the image.

[0016] (6) The housing may have a base therein on which the plate-like member is placed, and the upper surface of the base may have a different color or pattern between the area on the first direction side of the plate-like member and the area on the second direction side.

[0017] In this way, the difference in color or pattern between the area on the first direction side and the area on the second direction side of the base can enhance the three-dimensional effect of the image.

[0018] (7) The housing may have a first surface and a second surface opposite to the first surface, and may have a base therein on which a plate-shaped member is placed on the first surface side, the base including a light-transmitting region that provides communication between the first surface and the second surface, and the base may have an emitter for irradiating light onto the light-transmitting region.

[0019] In this way, a visual effect can be given to the user by illuminating the base.

[0020] (8) A light guide plate facing the second surface is provided, and the light emitter causes light to enter the light guide plate. It is preferable that the device is a display device.

[0021] In this way, the transmissive area provided on the base can be illuminated by a smaller number of light-emitting elements.

[0022] (9) The plate-like member may be a display that displays an image in response to an input signal, and the image display unit may be a display device that supplies the signal to the display.

[0023] In this way, the image displayed on the translucent plate-shaped display element, combined with the first and second regions that exist in the space between the translucent region and the plate-shaped member and sandwich the plate-shaped member from both sides when viewed from the first direction side, can give the user a three-dimensional sense of the image, enhancing the visual effect of the display device.

[0024] (10) The display device may include a first light-emitting portion that irradiates the display body with light from a second direction opposite to the first direction.

[0025] In this way, the display device can be made less susceptible to the influence of the brightness around the display device in order to display an image that is visible to the user.

[0026] (11) The first light-emitting section may include a plurality of light-emitting bodies provided along at least one side of the display body, and the plurality of light-emitting bodies may emit light in the second direction.

[0027] In this way, by shining light into the space in front of and behind the display, it is possible to give the user the visual effect that the image is placed in a bright space.

[0028] (12) The display device may further include a second light-emitting section that irradiates the display body with light from the first direction, the first light-emitting section emitting light with a higher brightness than the second light-emitting section.

[0029] In this way, even if the luminance of the second light-emitting portion is relatively low, it is possible to give the user the visual effect of seeing the image placed in a bright space.

[0030] (13) The image display unit may be a display device disposed in a first space below the display body of the housing.

[0031] This makes it easier to make the space above the display smaller than the space below, and increases the sense of stability in the position of the display device.

[0032] (14) The display device may be such that the housing has a cylindrical shape, the transmissive area is an opening, and a translucent member is disposed in the opening.

[0033] In this way, a cylindrical display device with excellent design can be provided.

[0034] (15) The housing may be a display device having a door that can be opened and closed on the first direction side or the second direction side of the plate-like member.

[0035] In this way, an object can be placed inside the housing, and a visual effect that matches the object can be obtained.

[0036] The inventions shown in (1) to (15) above can be arbitrarily combined. For example, it is preferable to add at least a part of the configuration of at least one of the inventions after (2) to all or a part of the configuration of the invention shown in (1). In particular, it is preferable to add at least a part of the configuration of at least one of the inventions after (2) to the invention shown in (1). In addition, it is also possible to extract any configuration from the inventions shown in (1) to (15) and combine the extracted configurations. The applicant of this application intends to obtain rights to the inventions including these configurations. In addition, even if there is a description such as "in the case of" or "when", it is not intended to describe the configuration as being limited to that case or time. These are examples of better configurations, and the applicant intends to obtain rights to configurations other than these cases or times. In addition, the parts described in order are not limited to this order. Configurations in which some parts have been deleted or the order has been changed are also disclosed, and the applicant intends to obtain rights. Effect of the Invention

[0037] According to the present invention, the visual effect of the display device can be improved.

[0038] The effects of the invention of this application are not limited to this, and effects obtained from the configuration disclosed in the specification and drawings, etc. are also disclosed, and the intention is to obtain rights to the configuration that achieves the effects by divisional applications, amendments, etc. For example, in this specification, the phrase "can" is a description that clearly indicates the effect that is achieved, and there are also parts that show the effect even without the phrase "can." Also, there are effects that can be understood from the configuration even without such a description. [Brief description of the drawings]

The plan view of the display device 1 is a view of the display device 1 as viewed from above. The bottom view of the display device 1 is a view of the display device 1 as seen from below. Fig. 8 is a cross-sectional view (VIII-VIII horizontal cross-sectional view in Fig. 5(a)) of the display device 1 cut in the width direction (left-right direction in this embodiment). Fig. 9 is a cross-sectional view (IX-IX vertical cross-sectional view in Fig. 5(a)) of the display device 10 cut in the top-bottom direction. Fig. 10 is an exploded perspective view of the housing 100.

[0045] The display device 1 has a cylindrical appearance. The size and weight of the display device 1 are such that the user can hold it in one hand and carry it around. The user uses the display device 1 by placing it on a flat surface such as a desk. The display device 1 is longer in the vertical direction than in the width direction. The ratio of the width direction length of the display device 1 to the vertical direction length is approximately 2:1. For example, the vertical length of the display device 1 is 230 mm, and the width direction length is 140 mm.

[0046] The display device 1 includes a housing 100, a display body 200, and a cover 300. The housing 100 has the display body 200 inside. The display body 200 is a plate-like member having translucency. The display body 200 is arranged to face the front of the display device 1. A user views an image displayed on the display body 200 from the front side of the display device 1. The cover 300 covers the housing 100 from the front side. The display body 200 is arranged in a space surrounded by the housing 100 and the cover 300. The cover 300 overlaps with the display body 200 when viewed from the front side. The cover 300 is transparent and does not impede the user's viewing of the image.

[0047] (2-1. Housing 100) The housing 100 has a cylindrical appearance. The corners of the housing 100 are rounded (for example, the radius of curvature may be small). The surface of the housing 100 is matte-finished to give it a textured appearance. In this way, a cylindrical display device 1 with excellent design is provided. The color of the outer surface of the housing 100 is not important, but it is preferable to use white or black, which gives a sense of luxury or simplicity. The housing 100 is preferably made of a resin material, but may also be made of metal or other materials.

[0048] The housing 100 includes a front case part 101, a rear case part 102, an upper lid part 103, a lower case part 104, a base 105, and a lower lid part 106. The housing 100 is configured by combining the front case part 101, the rear case part 102, the upper lid part 103, the lower case part 104, the base 105, and the lower lid part 106.

[0049] The front case part 101 is a cover that covers the front side (for example, the front half) of the display device 1. The front case part 101 is curved so that the vicinity of the center in the width direction protrudes most forward. The upper end surface of the front case part 101 is semicircular arc shaped.

[0050] The front case part 101 has an opening 1011 facing at least forward, which is a first direction. The opening 1011 is provided at a position corresponding to a side surface of the cylindrical housing 100. The opening 1011 communicates the internal space of the housing 100 with the external space. When the display device 1 is viewed from the front side, the opening 1011 is a rectangle that is longer in the vertical direction than in the width direction. The opening 1011 is open downward, and is not open to the upper, right, or left.

[0051] The front case part 101 has an inclined region 1012 on the left side of the opening 1011, and an inclined region 1013 on the right side of the opening 1011. The inclined regions 1012 and 1013 are disposed in a space between the opening 1011 and the display body 200. The inclined regions 1012 and 1013 are a first region and a second region sandwiching the display body 200 from both sides in the width direction when viewed from the front side. The inclined regions 1012 and 1013 are inclined in a direction away from each other from the display body 200 side toward the front side. Therefore, the inclined regions 1012 and 1013 have a shape that spreads left and right from the display body 200 toward the front. The closer the inclined regions 1012 and 1013 are to the display body 200, the closer they are to a direction perpendicular to the surface direction of the display body 200, and the closer they are to the opening 1011 side, the closer they are to the surface direction of the display body 200. However, the inclined regions 1012 and 1013 may be inclined at a certain angle.

[0052] It is desirable that there is no gap between the inclined regions 1012, 1013 and the display body 200, or that the gap is almost invisible to the user. The color or pattern of the inclined regions 1012, 1013 may be different from other regions of the front case part 101 and the inner peripheral surface 1029 (third region) of the rear case part 102. For example, it is desirable to provide a contrast difference by making the inclined regions 1012, 1013 black and the other regions of the front case part 101 and the inner peripheral surface 1029 white.

[0053] The front case part 101 has an inclined region 1014 above (in the third direction) the space between the opening 1011 and the display body 200. The inclined region 1014 corresponds to the ceiling of the internal space of the housing 100. The inclined region 1014 is a fourth region that exists between the inclined region 1012 and the inclined region 1013. The inclined region 1014 inclines upward from the display body 200 side toward the front side. When viewed from the front side, the inclined region 1014 inclines upward in a direction away from the display body 200. The inclined region 1014 inclines upward at a constant angle.

[0054] A sound pressure transmitting area 1015 is provided on the front surface of the front case part 101 above the opening 1011. The sound pressure transmitting area 1015 is an area that outputs sound from a speaker (speaker unit 511 described later) provided inside the housing 100 to the outside. Here, the sound pressure transmitting area 1015 is an opening provided in the front case part 101. However, the sound pressure transmitting area 1015 may be any area that transmits sound pressure, and may be provided with a member such as a grill.

[0055] As shown in Fig. 4, a light-transmitting region 1016 is provided in the vicinity of the display body 200 in the inclined region 1014. The light-transmitting region 1016 is provided in the center in the width direction of the inclined region 1014. As shown in Fig. 9, the light-transmitting region 1016 transmits light L from a light-emitting body (light-emitting body 521 described later) provided inside the housing 100. The light L is irradiated onto the display body 200 from the front side.

[0056] The rear case part 102 is a cover that covers the rear side (for example, the rear half) of the display device 1. The rear case part 102 is curved so that the vicinity of the center in the width direction protrudes furthest rearward. The upper end surface and the lower end surface of the rear case part 102 are semicircular arc shaped. The rear case part 102 has recesses 1021, 1022 in positions close to the upper end surface and in the vicinity of both left and right ends. A user can also insert fingers into the recesses 1021, 1022 to hold the display device 10. The rear case part 102 is fixed to the front case part 101 by using screws 901, 902 in the recesses 1021, 1022, respectively.

[0057] The upper lid portion 103 is a circular, flat, lid-like member when viewed from above. The upper lid portion 103 covers the front case portion 101 and the rear case portion 102 from above.

[0058] The lower case part 104 is a cover located below the display body 200 of the display device 1. The lower case part 104 has an upper surface and is cylindrical in shape, opening downward. As shown in FIG. 10, openings 1041 and 1042 are provided on both sides in the width direction of the upper surface of the lower case part 104, which allow the internal space of the lower case part 104 to communicate with the external space. In addition, a groove part 1043 extending in the width direction is provided on the upper surface of the lower case part 104 between the openings 1041 and 1042. A pedestal 105 is disposed on the upper surface of the lower case part 104. The pedestal 105 is a thin plate-like or sheet-like member having substantially the same shape as the upper surface of the lower case part 104. The pedestal 105 has a notch 1053 at a position overlapping the groove part 1043, and is cut out at positions overlapping the openings 1041 and 1042. Hereinafter, the region of the base 105 that is in front of the display body 200 may be referred to as the "front region 1051," and the region behind the display body 200 may be referred to as the "rear region 1052." The front region 1051 may be referred to as the region in front of the groove portion 1043 or the notch 1053, and the rear region 1052 may be referred to as the region behind the groove portion 1043 or the notch 1053. The lower opening of the lower case portion 104 is covered by the lower lid portion 106. The lower lid portion 106 is a circular, plate-like member. The lower lid portion 106 is fixed to the lower case portion 104 by using screws 911, 912, 913, and 914.

[0059] (2-2.Display body 200) The display body 200 is disposed inside the housing 100. The display body 200 is a display body that displays an image according to an input signal. The display body 200 is a display body having translucency, for example, a transparent liquid crystal. The display body 200 may be a display body using a display element other than a liquid crystal element, as long as it can transmit light in an area where no image is displayed. In addition, the display body 200 does not need to have translucency in its entirety, and it is sufficient that at least at least a part of an area that is visible to a user has translucency. The display body 200 does not necessarily need to be colorless and transparent. It is sufficient that the display body 200 can transmit light to an extent that the space behind the display body 200 can be visually recognized from the front side of the display body 200.

[0060] The display body 200 displays a multi-color image. The display body 200 includes a plurality of pixels (e.g., 400×800 pixels), and displays an image with a plurality of gradations (e.g., 256 gradations) for each of the color components red, green, and blue for each pixel. A user of the display device 1 visually recognizes the image displayed on the display body 200 through the opening 1011 and the cover 300. For this reason, the opening 1011 can be said to be a light-transmitting region.

[0061] The display unit 200 is rectangular when viewed from the front side, and is longer in the vertical direction than in the width direction. The display unit 200 is erected on the base 105 so as to be perpendicular to the upper surface of the base 105. This causes the display unit 200 to face the opening 1011. The base 105 is arranged in the lower case part 104 in a state where it is inserted into the groove part 1043 and the notch 1053.

[0062] Display body 200 may be inclined with respect to the upper surface of base 105. Display body 200 is disposed in the center of base 105 in the front-rear direction, but may be disposed forward or rearward of the center.

[0063] Since the display body 200 is translucent, when a user views an image on the display body 200, the user can simultaneously view the rear region 1052 and an area of ​​the inner circumferential surface 1029 of the rear case portion 102 that is located on the rear side of the display body 200. The area located on the rear side of the display body 200 is an area of ​​the inner circumferential surface of the housing 100 that faces the display body 200. The display body 200 may have, for example, a refresh rate of 60 Hz and a frame rate of 30 Hz.

[0064] (2-3. Cover 300) The cover 300 is provided in the opening 1011. The cover 300 is a light-transmitting member that closes the opening 1011. Therefore, the cover 300 is curved so that the vicinity of the center in the width direction protrudes most forward. The upper end surface and the lower end surface of the cover 300 are semicircular arc-shaped. The cover 300 is, for example, colorless and transparent, but may be colored as long as the image on the display body 200 can be visually recognized by the user. The cover 300 may be formed, for example, using an acrylic material, but may be formed of glass or other materials. As shown in FIG. 8, the cover 300 is located at a position corresponding to a sector arc portion with a central angle θ of 120 degrees when viewed from above. However, the central angle θ may be less than 120 degrees or may be greater than 120 degrees (for example, 180 degrees).

[0065] (2-4. External input) The display device 1 has a function of accepting input of power and signals. In this embodiment, the display device 1 is connected to a power cable 410 and an HDMI (registered trademark) cable 420. The lower case part 104 is provided with an opening so that a power terminal (a power terminal 561 described later) for connecting the power cable 410 and a connector (a connector 562 described later) for connecting the HDMI cable 420 are exposed. The display device 1 accepts input of power for operation via the power cable 410 and operates using the power. The display device 1 accepts input of a signal indicating an image to be displayed on the display body 200 and an audio signal for audio output via the HDMI cable 420. The display device 1 may operate based on a battery or other power source. The display device 1 may also be connected to a cable of a standard other than HDMI (for example, USB).

[0066] (2-5. Dimensions) When the display device 1 is viewed from the front side, the vertical length H1 of the part of the front case part 101 located above the display body 200 is shorter than the vertical length H2 of the part located below the display body 200. This is suitable for making the weight of the lower side of the display device 1 greater than that of the upper side, and the display device 1 is less likely to fall over, and the display device 1 has a more stable posture and appears more stable. The vertical length H3 of the display device 200 is longer than H1 and H2. For example, H1=40 mm or less and H2=60 mm or less. When the display device 200 is a 7-inch liquid crystal display, H3 is 154 mm, which is the length of its active area. The widthwise dimension W1 of the display device 1 is 130 mm or less. When the display device 200 is a 7-inch liquid crystal display, the widthwise length W2, which is the length of its active area, is 86 mm.

[0067] <3. Internal configuration of display device 1> (3-1. Internal structure above the display body 200) Next, the internal configuration above the display body 200 will be described with reference to a diagram of the display device 1 with the upper cover part 103 removed. Fig. 11 is a perspective view of the display device 1. Fig. 12 is a plan view of the display device 1.

[0068] The rear case part 102 is fixed to the front case part 101 at the front side by using screws 921 and 922. The rear case part 102 includes a flat plate part 1025 extending in the front-rear direction and the width direction below the upper cover part 103. The flat plate part 1025 is a flat part located rearward of the display body 200. A speaker unit 511 and a substrate 510 are arranged on the upper surface of the flat plate part 1025. The speaker unit 511 is a speaker that outputs sound in response to an audio signal. The speaker unit 511 is preferably a high-quality speaker so that the display device 1 can function as an AI speaker. The substrate 510 is a substrate on which electronic components are provided, and is arranged so as to avoid the speaker unit 511. Here, an electronic component 512 such as a capacitor is mounted on the substrate 510.

[0069] The second light-emitting unit 520 is disposed in a position in front of the substrate 510 of the rear case 102 and sandwiched between the screws 921 and 922. The light-emitting body 521 is provided on the lower surface of the second light-emitting unit 520. The light-emitting body 521 is disposed in front of the display body 200. The light-emitting body 521 irradiates the display body 200 with light from the front side of the display body 200 through the light-transmitting region 1016. The light-emitting body 521 is preferably a light-emitting diode, but may be an organic EL or other light-emitting body. The light-emitting body 521 may be configured as a set of light-emitting bodies of the three primary colors of red, green, and blue, for example. In this way, various colors can be expressed by adjusting the balance of the luminance of red, green, and blue. The light-emitting body 521 may emit white light. The substrate 510 and the second light-emitting unit 520 are printed circuit boards (PCBs: Printed Circuit Boards).

[0070] (3-2. Internal structure of the rear side of the display body 200) The internal configuration of the rear side of the display body 200 will be described with reference to a diagram in which the rear case part 102 is removed from the display device 1. Fig. 13 is a rear view of the display device 1 with the rear case part 102 removed.

[0071] The first light-emitting unit 530 and the first light-emitting unit 540 are provided in the rear case part 102. The first light-emitting unit 530 is provided along one side of the right side extending in the vertical direction of the display body 200. The first light-emitting unit 540 is provided along one side of the left side extending in the vertical direction of the display body 200. The first light-emitting unit 530 and the first light-emitting unit 540 each have a longitudinal direction in the vertical direction. As shown in FIG. 8, the first light-emitting unit 530 is disposed in a recess 1023 of the rear case part 102 and emits light to the rear side. The first light-emitting unit 540 is disposed in a recess 1024 of the rear case part 102 and emits light to the rear side. The recesses 1023 and 1024 are open to the rear side of the display device 1.

[0072] The first light-emitting unit 530 includes a plurality of light-emitting bodies 531 arranged at a predetermined interval from each other in the vertical direction. The first light-emitting unit 540 includes a plurality of light-emitting bodies 541 arranged at a predetermined interval from each other in the vertical direction. The first light-emitting units 530, 540 emit light with a higher luminance than the second light-emitting unit 520. In this way, even if the luminance of the second light-emitting unit 520 is relatively lowered, a visual effect can be given to the user as if the character content 1000 is placed in a bright space. The plurality of light-emitting bodies 531 and the plurality of light-emitting bodies 541 emit light toward the rear side of the display device 1, illuminating the space surrounded by the display body 200 and the rear case part 102. The plurality of light-emitting bodies 531 and the plurality of light-emitting bodies 541 emit light to be irradiated to the display body 200. The light-emitting bodies 531, 541 function as a backlight for the display body 200. The light emitters 531 and 541 shine light into the space in front of and behind the display 200, giving the user a visual effect that the character content 1000 is placed in a bright space. The light emitters 531 and the light emitters 541 emit, for example, white light. The light emitters 531 and 541 are, for example, light-emitting diodes. The light emitters 531 and 541 may be organic EL or other light emitters. The first light emitter 530 and the first light emitter 540 are printed circuit boards. The light emitter 521 may be configured as a set of light emitters of the three primary colors of red, green, and blue. In this way, various colors can be expressed by adjusting the balance of the brightness of red, green, and blue. For example, the number of light emitters 531 may be six, and the number of light emitters 541 may be six.

[0073] 14 is a perspective view of the display device 1 when the front case part 101 is removed from the display device 1. The relay board 550 is provided along one side on the right side extending in the up-down direction of the display body 200. The relay board 550 is provided forward of the first light-emitting part 530. The relay board 550 has a longitudinal direction in the up-down direction, with its upper end being located at approximately the midpoint of the display body 200 in the up-down direction, and its lower end being located further below the opening 1041 of the base 105.

[0074] The relay board 550 relays the power input via the power cable 410 and the signal input via the HDMI cable 420 to the display body 200. The relay board 550 is physically and electrically connected to the display body 200 via a flexible printed circuit board 551. The display body 200 displays an image based on the power and the signal. The signal is a signal for operating the display body 200, for example, an image signal and a control signal (for example, a timing control signal, a scanning line driving signal, a data line driving signal). The relay board 550 may further supply a signal for driving the speaker unit 511 to the board 510 via wiring (not shown), or supply power for making the light emitter 521 emit light to the second light emitter 520 and the first light emitters 530 and 540. When the front case part 101 and the rear case part 102 are attached, the relay board 550 is located in a space sandwiched between them and is not visible to the user.

[0075] (3-3. Internal configuration of lower case portion 104) Next, the internal configuration of the lower case part 104 will be described. Fig. 15 is a perspective view of the display device 1 from which the lower case part 104 has been removed. Fig. 16 is a top view of the display device 1 from which the lower case part 104 has been removed. Fig. 17 is a bottom view of the display device 1 from which the lower cover part 106 has been removed.

[0076] An interface board 560 and a main board 570 are arranged inside the lower case part 104. The interface board 560 is a printed circuit board having a power terminal 561 to which the power cable 410 is connected and a connector 562 to which the HDMI cable 420 is connected, provided on the lower surface. The interface board 560 supplies power and signals to the main board 570 via a cable 565 (FPC) routed from the lower surface side to the upper side.

[0077] The main board 570 is a printed circuit board arranged on the interface board 560 so that at least a portion of the main board 570 overlaps with the interface board 560. The main board 570 is physically and electrically connected to the relay board 550 via a cable 575. The main board 570 functions as an image display unit that displays an image on the display body 200. The main board 570 supplies a video signal, an audio signal, and a control signal (for example, a signal for driving the display body 200) to the relay board 550. This causes sound to be output from the speaker unit 511 and controls the display of the display body 200. In addition, the main board 570 supplies power to the first light-emitting unit 530 and the first light-emitting unit 540, respectively, for causing the light-emitting bodies 531 and 541 to emit light.

[0078] As described above, the inclined region 1014 of the front case part 101 is inclined upward toward the front. This is in consideration of the user's line of sight from above. In this way, it is possible to make it easier for the user to view the image, even if the user's line of sight is inclined slightly upward from the front, compared to when the inclined region 1014 is not present.

[0079] The inclined regions 1012, 1013 of the front case part 101 are shaped to expand forward on both sides in the width direction. The inventors discovered that, in this way, the display body 200 and the inclined regions 1012, 1013 work together to enhance the three-dimensional effect of the image, compared to a case in which there are no inclined regions.

[0080] The color or pattern of the inclined regions 1012, 1013 may be different from that of the regions on the inner circumferential surfaces of the front case part 101 and the rear case part 102. The difference in the sense of depth between the inclined regions 1012, 1013 and the regions on the inner circumferential surfaces of the front case part 101 and the rear case part 102 is emphasized, and the three-dimensional effect of the image can be further enhanced. The inventors have discovered that a visual effect of the character content 1000 dancing behind the physical inclined regions 1012, 1013 can be given, further enhancing the three-dimensional effect. In this way, the display device 1 enhances the visual effect.

[0081] The display device 1 may have an operator and various sensors. The operation buttons may be arranged, for example, on the top surface of the upper lid part 103, on the front surface of the lower case part 104, or in a region in front of the cover 300 in the front region 1051. The main board 570 may move a cursor or control operation settings in response to an operation of the operation part. The operation part may be a physical button or a touch sensor (e.g., an electrostatic sensor). The display device 1 may also have an interface for wireless communication. In this case, the display device 1 may receive instructions from an external terminal such as a smartphone via wireless communication and perform various controls including displaying an image.

[0082] [Other embodiments] The present disclosure is not limited to the above-described embodiments, and can be modified as appropriate without departing from the spirit and scope of the present disclosure.

[0083] (1) A second frame 970, which will be described below, may be provided instead of the inclined regions 1012, 1013. Fig. 18 is a diagram showing the configuration of the periphery of a display body 200 of a display device according to one modified example. Fig. 18(a) is a diagram showing the configuration of the periphery of the display body 200 as viewed from the right side, and Fig. 18(b) is a diagram showing the periphery of the display body 200 as viewed from the front side.

[0084] In the above-described embodiment, the periphery of the upper end surface, the left end surface, and the right end surface of the peripheral portion of the display body 200 are sandwiched between the front case part 101 and the rear case part 102, and the periphery of the lower end surface is supported by the lower case part 104. That is, the periphery of the display body 200 is surrounded by the first frame body. As a result, as shown in FIG. 18(a), the area of ​​the display body 200 facing the opening 961 corresponding to the opening of the first frame body is exposed to the front side. Furthermore, the second frame body 970 is provided in front of this first frame body. The second frame body 970 is disposed a predetermined distance D forward of the first frame body, and has an opening 971 in an area overlapping with the opening 961 when viewed from the front. Moreover, the second frame body 970 not only sandwiches the display body 200 from both sides in the width direction when viewed from the front side, but also sandwiches the display body 200 from both sides in the vertical direction.

[0085] As shown in FIG. 18(b), the display body 200 has a width W4 and a vertical length H4. The opening 961 has a width W5 and a vertical length H5. The opening 971 has a width W6 and a vertical length H6. The predetermined distance D is, for example, 1 to 2 cm. The inventors confirmed that, in this way, the user sees the character content 1000 moving on the back side of the second frame 970, improving the three-dimensional effect. In addition, when a user moves left and right in front of the second frame 970, the user sees a visible area of ​​the display body 200 on the side where the second frame 970 is placed. Therefore, a secondary effect (for example, a promotional effect) can be expected in which a person who sees the user moving left and right in this way becomes interested in the person who is moving left and right and wondering what is going on.

[0086] (2) First light-emitting part In the above-described embodiment, the first light-emitting unit that illuminates the display body 200 from behind is realized using the first light-emitting unit 530 and the first light-emitting unit 540. However, this is not limiting and various modifications are possible.

[0087] FIG. 19 is a view of the display device 1 with a part of the rear case part 102 removed, viewed from slightly below. As shown in FIG. 19, the first light emitter 600 may emit light from the ceiling region 1026 of the rear case part 102. In this case, the first light emitter 600 includes a light emitter 610 and a plate-shaped light guide plate 620, and emits light toward the display body 200 from an obliquely upward direction rearward of the display body 200. The light emitter 610 causes light to enter one end surface of the light guide plate 620. The light guide plate 620 is disposed in the ceiling region 1026. The light guide plate 620 diffuses the light from the light emitter 610 to form a strip-shaped light, which is emitted toward the display body 200.

[0088] In this configuration, a reflector may be provided on the base 105. The reflector may have a sloped area so as to reflect the light forward. The reflector may be a mirror or other reflective member.

[0089] (2) Second light-emitting section In the above-described embodiment, the second light-emitting unit that illuminates the display body 200 from the front side is realized using the second light-emitting unit 520. However, the present invention is not limited to this, and various modifications are possible.

[0090] FIG. 20 is a view of the internal space of the display device 1 seen from above. As shown in FIG. 20, the second light-emitting units 600B, 600C may irradiate light from the diagonally forward side of the display body 200. In this case, the second light-emitting units 600B, 600C may have the same configuration as the first light-emitting units 530, 540 so that the second light-emitting units 600B, 600C emit light toward the center of the display body 200. In this case, it is desirable that a part of the housing 100 is present behind the second light-emitting units 600B, 600C so that the second light-emitting units 600B, 600C are not visually observed by the user. FIG. 21 is a photograph showing a prototype example of the display device 1 with this configuration. As shown in FIG. 21, the display of the character content 1000 was confirmed.

[0091] (4) Illumination of pedestal 105 The base 105 may be configured to light up like a stage tag. FIG. 22 and FIG. 23 are views of the internal space of a display device according to a modified example viewed from above. FIG. 22(a) shows a configuration in which the base 105 has a light-emitting region T1 in the front region 1051. FIG. 22(b) shows a configuration in which the base 105 has a light-emitting region T2 in the rear region 1052. FIG. 23 shows a configuration in which the base 105 has a light-emitting region T3 in the front region 1051 and the rear region 1052. Here, the light-emitting regions T1 and T2 are each a semicircular arc-shaped region, but this is merely an example. Also, the light-emitting region T3 is annular, but this is merely an example. The following configuration may be adopted as a mechanism for making the light-emitting region emit light. In the following, a case in which light-emitting regions exist in the front region 1051 and the rear region 1052 as shown in FIG. 23 will be described as an example, but a similar configuration may be adopted when the light-emitting region exists in either one of them.

[0092] FIG. 24 is a view of the configuration around the base 105 seen from the right. In this example, a method is adopted in which a pattern corresponding to a light-emitting area is drawn on an acrylic plate, and the drawn area is illuminated. The base 105 has a first surface 1054 and a second surface 1055 facing the first surface 1054, and the display body 200 is disposed on the first surface 1054 side. The base 105 includes a light-transmitting area T that communicates the first surface 1054 with the second surface 1055. The light-transmitting area T may be, for example, a hole provided in the base 105, or may be an area in which a member having light-transmitting properties is disposed. The display device 1 has a light guide plate 720 facing the second surface 1055, and a light emitter 710 that inputs light to the light guide plate 720. The light guide plate 720 is, for example, an acrylic plate. The base 105 has a light-transmitting area T that corresponds to the light-emitting pattern. The area of ​​base 105 other than light-transmitting area T is made of an opaque material and functions as a mask area. Base 105 may be formed as a mirror surface by applying metal deposition or the like to first surface 1054 of an acrylic plate with an engraved pattern. This allows for the expression of depth.

[0093] The light emitter 710 emits light into the end face of the light guide plate 720. The light emitter 710 is preferably configured as a set of light emitters of the three primary colors of red, green, and blue, but may be configured with other colors. The light guide plate 720 guides the light from the light emitter 710 to the front side, forms a strip of light, and emits it toward the base 105. Of the light emitted from the light guide plate 720, the light that enters the light-transmitting region T passes through the light-transmitting region T and is emitted above the base 105. The light that enters the region of the base 105 other than the light-transmitting region T is blocked by this region and is not emitted above the base 105. In this way, it is not necessary to provide a light emitter for each light-emitting position, and the base 105 can be illuminated with fewer light emitters. This light is expected to improve the presentation effect. In addition, since the light emitter 710 is provided behind the display body 200, the user can see the light even from the front. However, the light emitter 710 may emit light from the front of the display body 200 .

[0094] 24, a light guide plate 740 may be disposed below the light guide plate 720. In this case, the light emitter 710 emits light to one end surface of the light guide plate 740. The light guide plate 740 diffuses the incident light to form a band-like light, and emits it toward the light guide plate 720.

[0095] 25, base 105A may be formed of a light guide plate having a recess 751 (here, semicircular) in the light emitting region. In this case, light emitter 710 emits light into one end surface of base 105A. The surface of base 105A may be processed so that the light diffused by base 105A is emitted upward from recess 751 and does not exit from other regions.

[0096] (5) Background example 1 (inner peripheral surface 1029) As shown in FIG. 26, a first background portion 810 may be provided behind the display body 200 and facing the display body 200. Here, the first background portion 810 is a region arranged to cover the inner circumferential surface 1029 of the rear case portion 102. The first background portion 810 is, for example, a medium on which an image showing a background such as the sky or the sea has been formed in advance. The first background portion 810 is, for example, a sheet-like medium made of paper, resin, or the like. However, the first background portion 810 may be specified by a region of the inner circumferential surface 1029 on which the background image is drawn.

[0097] The first background portion 810 shows, for example, an image imitating a wall pattern, a gradation, or a geometric pattern. For example, as shown in FIG. 28(a), the first background portion 810 may be an image that transitions from white to black continuously or stepwise from bottom to top. As shown in FIGS. 28(b) to (d), the first background portion 810 may be an image that is white in the center in the width direction and transitions to black continuously or stepwise toward the periphery. In this way, a region with a different color or pattern from the region in front exists behind the display body 200, and the three-dimensional effect of the image is further improved.

[0098] (6) Background example 2 (pedestal 105) An image showing a background may be formed on the upper surface of the base 105. The image on the upper surface of the base 105 may be, for example, an image of the ground or floor, a gradation, or a geometric pattern. As shown in FIG. 29(a), the base 105 may be formed with an image of a plurality of straight lines extending in the front-rear direction of the display device 1, such that the width between the lines becomes shorter toward the rear side. As shown in FIG. 29(b), the base 105 may be formed with an image of a checkerboard pattern including a plurality of diamond shapes in which two types of diamond shapes with different shadings are alternately arranged. In addition, the base 105 may be formed with a pure white image, or may be formed with an image that is white in the center and transitions to black continuously or stepwise on the outside (here, in the radial direction) as shown in FIG. 30(a) and (b). The base 105 may be formed with an image that resembles a hole in order to express a sense of depth in the front-rear direction as shown in FIG. 30(c) and (d). As shown in FIG. 31(a), the base 105 may have an image formed thereon in which the density changes continuously or stepwise from the front side to the rear side. The image may be, for example, yellow or another color. As shown in FIG. 31(b), the base 105 may have an image formed thereon in which rectangular or square images of two different colors are alternately arranged in the front-rear direction and the width direction. The inventors have found that a particularly high three-dimensional effect of the image can be obtained by using a checkered image in which the space between the lines is wider, the line width is thicker, and the density is higher toward the rear side as shown in FIG. 32(a), or by using a checkered image in which the space between the lines is narrower, the line width is thinner, and the density is lower toward the rear side as shown in FIG. 32(b).

[0099] In this way, the character content 1000 is given the impression of standing on the pedestal 105, and the three-dimensional effect of the image is enhanced. The pedestal 105 may be a pure white image, or an image that is white in the center and darkens toward the periphery. The pedestal 105 may not be arranged parallel to the upper surface, but may be inclined, for example, so that it is higher on the rear side. In this way, the color or pattern of the area behind the display body 200 on the upper surface of the pedestal 105 is different from that of the area in front of the display body 200, thereby enhancing the three-dimensional effect of the image.

[0100] Fig. 33 is a photograph showing a prototype of a display device with this configuration. As shown in Fig. 33(a) and (b), the display of character content 1000 was confirmed.

[0101] The base 105 may be replaceable. In this case, an opening for inserting and removing the base 105 into and from the housing 100 may be provided in the housing 100.

[0102] (7) Background example 3 (inner peripheral surface 1029) As shown in FIG. 34, a first background section 830 (third region) may be provided behind the display body 200 and facing the display body 200. A light guide plate 840 is arranged along the inner circumferential surface 1029. The first background section 830 is a sheet-like medium having translucency and is arranged along the inner circumferential surface 1029 on the front side of the light guide plate 840. A light emitter 850 arranged on one end side of the light guide plate 840 makes light incident on one end surface of the light guide plate 840. The light guide plate 840 diffuses the light from the light emitter 850 to illuminate the first background section 830 from the rear side. The image of the first background section 830 is not particularly limited, but it is preferable that it is expressed in a lighter color than the image of the display body 200. In addition, if the first background section 830 can be changed according to the season of the calendar or the like, visual interest will increase. The part of the first background section 830 located on the rear side of the character content 1000 may be white. This makes it easier to see the characters. The first background portion 830 may be configured to display white color using a transparent liquid crystal or the like. In this way, it can be used with a backlight.

[0103] Figure 35 is a photograph showing a prototype of a display device with this configuration. It was confirmed that the character and background are combined to create a three-dimensional effect. This is suitable for displaying semi-transparent images such as holograms.

[0104] Also, in the inclined region 1014, a pattern may be applied so that the closer to the display body 200, the darker the pattern becomes.

[0105] (8) Background example 4 (changing the background) The display device 1 may be configured so that the color or pattern of the base 105 can be changed. For example, the base 105 may be configured with a liquid crystal display, an organic electroluminescence (EL) display, or other display body. The display body is preferably a dot matrix display, but may be a segment type. The display device 1 may be configured so that the base 105 can be replaced. In this case, an opening for inserting and removing the base 105 into and from the housing 100 may be provided in the housing 100. In this case, an opening for inserting the front region 1051 and an opening for inserting the rear region 1052 may be provided separately. For example, a slit for inserting and removing a medium may be provided on the front or rear surface of the housing 100 so that the medium to be used as the base 105 can be pulled out, and the medium may be inserted and removed through this slit. In this way, the first background unit 810 may also be configured with a liquid crystal display, an organic electroluminescence (EL) display, or other display body. The first background unit 810 may be a normal dot matrix display, but is preferably a curved display. The display device 1 may be configured so that the first background unit 810 can be replaced. In this case, an opening for inserting and removing the first background portion 810 into and from the housing 100 may be provided in the housing 100 .

[0106] (9) Members on the base 105 As shown in Fig. 36, an opaque member 900 may be provided at a position overlapping the bottom end surface of the display body 200 when viewed from the front. Here, the member 900 is in the shape of a rectangular parallelepiped, but it may also be a cube or other polyhedron, or a cylinder. In this way, the physical member 900 can be seen as a stage on which the character content 1000 stands. This allows the user to obtain the visual effect of the character content 1000 standing on a stage.

[0107] 37 is a photograph showing a prototype of a display device with this configuration. By having the character's feet come into contact with the member 900, the visual effect of the feet landing on the ground can be reproduced.

[0108] (10) As shown in FIG. 38, for example, by making the brightness of the panel P1 on the front side of the display body 200, the base 105, and the panel P2 on the upper side of the display body 200 different, the effect of increasing the three-dimensional effect of the character content 1000 can be expected. For example, the display body 200 appears three-dimensional when the rear side is bright and the base 105 is dark. Even if the rear side of the display body 200 is dark and the base 105 is bright, the display body appears three-dimensional. From this, it is considered that the three-dimensional effect of the image is increased by making the display difference such as color or pattern different between the area in front of the display body 200 and the area behind the display body 200. In addition, by brightly illuminating the rear side of the display body 200, the user can view the image of the display body 200 even if the environment around the display device 1 is dark, and the surroundings of the character can be displayed brightly.

[0109] (11) The main substrate 570 may control the light emission of the light emitters 521, 531, and 541 in response to the display of the character content. For example, the main substrate 570 adjusts the light emission brightness so as to give the impression that the character content is actually in the space.

[0110] (12) The display device 1 may be provided with a door that can be opened and closed. FIG. 39 is a diagram showing the configuration of a display device of this modified example. As shown in FIG. 39(a), a removable door 1027 may be provided on the rear case part 102. The door 1027 may be removable by pulling a handle 1027A, but may also be in the form of a door that can be slid left and right or pulled toward the user. This allows an object to be placed inside the housing 100 behind the display body 200, and a visual effect can be expressed in which the object and the image of the display body 200 are combined.

[0111] Also, a door that can be opened and closed may be provided on the front side of the display device 1. For example, as shown in FIG. 39(b), the cover 300 may function as a door that slides along the outer surface of the housing 100 as indicated by the arrow Ar. However, the cover 300 may be in the form of a door that can be pulled forward. This allows an object to be placed on the front side of the display body 200, and a visual effect that combines the object with the image of the display body 200 can be expressed.

[0112] (13) As shown in Fig. 40(a), a pair of side walls 910, 920 may be provided behind the display body 200 such that the distance between them becomes narrower toward the rear side than toward the front side. As shown in Fig. 40(b), a ceiling area 1028 may be provided behind the display body 200, sloping in a direction approaching the base 105 (i.e., downward) toward the rear side than toward the front side. In this way, the gaps on the rear end sides of the side walls 910, 920 and the rear end side of the ceiling area 1028 are displayed brighter, enhancing the three-dimensional effect of the image.

[0113] (14) In the above-described embodiment, the display body 200 displays an image. A transparent plate-like member may be disposed instead of the display body 200, and a projector may project an image onto the plate-like member. In this case, the display device may have an image display unit that projects an image onto the plate-like member from the rear side of the plate-like member.

[0114] (15) The display device 1 may change the orientation of the image depending on the change in posture. The display device 1 may have, for example, an acceleration sensor, and may set the orientation of the image so that the up-down direction in the vertical direction coincides with the top-bottom direction of the image, and display the image on the display body 200. For example, if the display device 1 is in a posture rotated by 90 degrees, the image is processed and displayed as an image rotated by 90 degrees.

[0115] (16) The display device is not limited to a cylindrical shape, and may be a cube, a rectangular parallelepiped, other polyhedrons, a sphere, or other shapes. The shapes, structures, dimensions, colors, patterns, etc. of the components of the display device 1 described above are merely examples. Some of the components of the display device 1 described above may be omitted, or other components may be added.

[0116] (17) The display device 1 may control the display of the display body 200 or control the audio output from the speaker unit 511 according to the sensor. The sensor is a sensor that detects a camera, a microphone, an odor, air pressure, and a gesture. The main board 570 may control the display of an image based on the detection result of the sensor. For example, the main board 570 may recognize the facial expression of the user with a camera and change the facial expression of the character. The main board 570 may also perform dialogue processing so that a pseudo dialogue between the character and the user is established based on a voice signal input to the microphone. The main board 570 may also output a greeting or other voice when it detects the presence of a person based on a microwave sensor. The main board 570 may change the character's behavior or dialogue processing accordingly when it detects an odor such as a gas odor or a burnt odor based on an odor sensor. The main board 570 may detect wind by a change in air pressure. The control board may control the display of the character content based on the user's behavior detected by a gesture sensor. For example, main board 570 may move or rotate the character in the direction in which the user performs a hand-waving operation.
