Description

Technology Field

[0001] The present invention relates to a dome structure for a display, and more specifically, to a dome structure for a display capable of providing structural stability and immersive images. Background Technology

[0002] A dome-shaped display is installed in the dome structure to match the curvature of the dome, and images are displayed on the screen. The dome structure can have curved domes of various shapes, such as hemispherical, bulbous, partial spheres, or elliptical. The dome-shaped display can be manufactured and installed to correspond to the shape of the dome, and by displaying images on the curved screen, it provides the audience with an immersive visual experience.

[0003] In the center of a conventional dome, a pole is located to support the load of the dome and to serve as the central boundary surface for multiple display modules or cladding. A dome-shaped display is formed by assembling multiple modules to create a single curved surface, and each module can be positioned relative to the central pole.

[0004] As a result, when an audience watches a video while seated, the pole is positioned in the center of their field of vision, which can impede immersion. Depending on its shape and placement, the pole may form visually distracting boundaries or expose seams and connections. Additionally, non-uniformity in pixel spacing between display modules or geometric distortion is prone to occur in areas adjacent to the pole, which can significantly reduce the visual uniformity and immersion of the video.

[0005] Meanwhile, conventional dome structures may have a latitude-longitude spoke structure that divides the curved surface, similar to the Earth's latitude and longitude. In this case, the curved frame of the dome forms divided areas to accommodate display modules. The display modules can be manufactured to fit the curvature, size, and shape of each divided area of ​​the curved frame of the dome.

[0006] However, it is not easy to accurately machine the display module into each segmented area of ​​the curved frame, and there are limitations in compensating for minute differences in height and angle (slope) between display modules.

[0007] Accordingly, visual seams, shadows, and unevenness may occur at the joints between display modules, which can impair the audience's immersion and the sense of unity in the video. Specifically, lines or gaps occurring at the boundaries where display modules meet may be noticeable, making the screen appear fragmented, and uneven lighting may occur due to unevenness between display modules, resulting in dark areas.

[0008] Therefore, there is a need to design the display module and the dome structure on which the display module is installed more efficiently. Prior art literature

[0040] FIG. 1 is a perspective view of a dome structure for a display according to an embodiment of the present invention, and FIG. 2 shows the components constituting the dome structure for a display of FIG. 1 separated. FIG. 3 is a rear perspective view of the dome structure for a display of FIG. 1, and FIG. 4 shows a side view of the dome structure for a display of FIG. 1.

[0041] Referring to FIGS. 1 to 4, a dome structure (100) for a display according to an embodiment of the present invention includes a main frame (200), a subframe (300), a cabinet (400), and a display (500). In the embodiment of the present invention, a dome structure (100) for a display having a hemispherical dome shape is described as an example, but in other examples, it can be implemented in various curved dome shapes such as bulb shapes or elliptical shapes.

[0042] The main frame (200) forms the outer surface of the dome and supports the load of the dome. The main frame (200) has a pole area (P1) formed in the central part and can form a hemispherical structure. The main frame (200) can be provided as a self-supporting steel space frame that supports structural loads and can stably support the structure independently without relying on external structures. The main frame (200) can evenly distribute loads such as dead load, live load, and wind load to the foundation through a radial truss system.

[0043] The subframe (300) is provided in a grid structure to form a curved surface corresponding to the dome shape and is coupled to the inner side (front) of the main frame (200). The subframe (300) may be provided in a curved structure including a longitudinal frame (310) and a transverse frame (320) arranged to match the installation spacing of the cabinet (400). The subframe (300) can be aligned to exactly match the curvature of the dome and can serve to set the exact installation position of the cabinet (400).

[0044] Cabinets (400) are each mounted at a set position inside the subframe (300). Cabinets (400) may be composed of modular cabinets designed to correspond to the curvature of the dome, and each cabinet (400) may be fixed to the subframe (300) at an accurate pitch and angle to provide a constant installation reference point across the entire curved surface area. Cabinets (400) can efficiently transport and support the display module (510).

[0045] The display (500) is mounted on the front of the cabinet (400) and has a display module (510) arranged in a curved shape corresponding to a dome shape.

[0046] Below, each component of the dome structure (100) for display will be described in detail.

[0047] The main frame (200) includes a rim frame (210) that forms the front edge of the dome in a curved shape, and a meridian frame (220) that is formed to match the curvature of the outer surface of the dome and is arranged at regular intervals in the direction of meridian, with one side connected to the rim frame (210) and the other side supported by the ground.

[0048] Additionally, the main frame (200) may include latitude frames (230) formed to match the outer curvature of the dome and arranged at regular intervals in the latitude direction.

[0049] The rim frame (210) is a structure formed along the front outer edge (front rim) of the dome, and can form a hemispherical outline when the curved dome is viewed from the front.

[0050] The perimeter frame (210) can be provided as a tetrahedral frame structure that continues along the front perimeter of the dome.

[0051] The border frame (210) may include a pair of border forming members (212) arranged side by side along the upper and lower sides of the front border of the dome in a curved shape, and a border connecting member (214) that connects the border forming members (212) to each other in a vertical and horizontal manner.

[0052] The line frame (220) can be provided as a rectangular frame structure that continues in the longitudinal direction along the outer surface of the dome.

[0053] The meridian frame (220) may include a first meridian support member (221) formed to match the outer curvature of the dome, a second meridian support member (222) arranged side by side above the first meridian support member (221), and a vertical reinforcing member (223) vertically connecting the first meridian support member (221) and the second meridian support member (222).

[0054] Here, the second meridian support member (222) is formed with a curvature corresponding to the first meridian support member (221) from the upper to the lower direction of the dome, and can form a vertical extension part (222a) that extends vertically toward the ground at a set height.

[0055] The vertical extension (222a) is configured to extend vertically toward the ground from the bottom of the curved portion of the second meridian support member (222) at a set height, and can serve as a structural base capable of transmitting a load to the ground. This is advantageous for increasing the support stability of the dome structure (100) and strengthening structural safety against external forces (e.g., gravity, vibration, wind, etc.).

[0056] The vertical extension (222a) can serve as an alignment reference point with the reference plane (ground) at the construction site and can contribute to ensuring geometric alignment when the main frame (200) and the subframe (300) are combined.

[0057] The latitude frame (230) is formed to match the curvature of the outer surface of the dome and is arranged at regular intervals in the latitude direction, and may include a footrest (232) and a triangular footrest support member (234) that supports the footrest (232) from the lower side.

[0058] A worker can climb onto the overhead frame (230) via an inspection ladder to perform tasks such as installing and maintaining facilities. Facilities such as piping and wiring can be installed on the overhead frame (230).

[0059] FIG. 5 shows a connection structure between a border frame and a meridian frame in a dome structure for a display according to one embodiment of the present invention.

[0060] Referring to FIG. 5, a dome structure (100) for a display according to an embodiment of the present invention may include a first connecting plate (242) attached to the top of a meridian frame (220), a second connecting plate (244) attached to one side of a border frame (210) so as to face the first connecting plate (242), and an inclined connecting member (246) that is manufactured to match the angle formed between the first connecting plate (242) and the second connecting plate (244), is positioned between the first connecting plate (242) and the second connecting plate (244), and connects the first connecting plate (242) and the second connecting plate (244) to each other.

[0061] Since the border frame (210) and the meridian frame (220) are arranged in a curved shape at a certain angle to each other, a stable and efficient connection structure between the border frame (210) and the meridian frame (220) can be formed through the first connecting plate (242), the second connecting plate (244), and the inclined connecting member (246).

[0062] FIG. 6 shows a bottom support structure that supports each edge frame and meridian frame in a dome structure for a display according to one embodiment of the present invention.

[0063] Referring to FIG. 6, a dome structure (100) for a display according to an embodiment of the present invention may include a support unit (600) that supports each edge frame (210) and a meridian frame (220).

[0064] The support unit (600) may include a support plate (610) coupled to the lower part of each edge frame (210) and line frame (220), a grout layer (620) filled between the support plate (610) and the ground, and a plurality of anchors (630) that are secured to the support plate (610) and fixedly installed on the ground by penetrating the grout layer (620).

[0065] The base plate (610) is connected to the lower part of each edge frame (210) and the meridian frame (220) to evenly distribute the load and stably support the structure. Each edge frame (210) and the meridian frame (220) can be connected to the base plate (610) by means of fastening means such as welding or bolts and nuts.

[0066] The grout layer (620) is filled between the base plate (610) and the ground, filling fine gaps and evenly transferring the load to the ground.

[0067] Since the grout layer (620) is filled with a fluid material, the height of the main frame (200) can be adjusted when constructing the dome structure (100) for display, and installation tolerances can be absorbed, which is advantageous for correcting construction deviations.

[0068] Additionally, the grout layer (620) can serve as an intermediate buffer layer and mitigate micro-vibrations or shocks from the floor surface being directly transmitted to the dome structure (100), thereby contributing to the extension of the structure's lifespan and stability.

[0069] The anchor (630) is a member that mechanically fixes the base plate (610) to the ground and can secure strong structural bonding by penetrating the grout layer (620).

[0070] The anchor (630) firmly secures the base plate (610) to the ground, thereby preventing the dome structure (100) from tipping over and detaching due to external loads (e.g., wind load, vibration, etc.).

[0071] FIG. 7 shows the position of a subframe coupled to a main frame being adjusted using a first position adjustment unit according to an embodiment of the present invention, and FIG. 8 is a perspective view of the first position adjustment unit illustrated in FIG. 7.

[0083] FIG. 11 illustrates a cabinet and a display module coupled thereto according to an embodiment of the present invention, and FIG. 12 illustrates a configuration for positioning a display module coupled to the cabinet illustrated in FIG. 11.

[0084] Referring to FIGS. 11 and 12, the cabinet (400) according to an embodiment of the present invention is formed to match the curvature of the subframe (300) as described above, and is positioned at each set position of the subframe (300) in which the longitudinal frame (310) and the transverse frame (320) are arranged according to the designed spacing.

[0085] The cabinet (400) may be provided with means such as a power supply unit (410) that supplies power to the display module (510) and a data transmission unit (420) that transmits data to the display module (510).

[0086] And, curved display modules (510) are each placed on the front of the cabinet (400). At this time, it is necessary to adjust the height difference between the display modules (510) so that alignment and a uniform surface are achieved between the display modules (510).

[0087] To this end, a dome structure (100) for display according to an embodiment of the present invention may include a module fixing bolt (910) that is screw-coupled to a coupling groove (400a) of a cabinet (400) to fix the display module (510) to the cabinet (400), and an adjustment screw (920) that is screw-coupled to the module fixing bolt (910) inserted inside and in close contact with the cabinet (400), and adjusts the height difference between the display modules (510) by moving the module fixing bolt (910) up and down according to the rotational direction.

[0088] The module fixing bolt (910) may be provided in a cylindrical shape, for example, and may include a bolt body (910a) that is coupled (fixed) to the rear of the display module (510), and a bolt coupling part (910b) that extends downward from the bolt body (910a), has a smaller diameter than the bolt body (910a), has threads formed on its periphery, and is fastened to the inside of the adjustment screw (920), with the end portion coupled to the coupling groove (400a) of the cabinet (400).

[0089] The adjustment screw (920) may have magnetic properties, thereby allowing for step adjustment between display modules (510) while the display modules (510) are attached to the cabinet (400).

[0090] Referring to FIG. 12 (a), for example, the second display module (510-2) has a relatively higher height at the boundary area where it is in close contact with the first display module (510-1), so a step difference occurs between the two modules (510-1, 510-2).

[0091] At this time, the height difference can be corrected (resolved) by rotating the adjustment screw (920), which is coupled with the module fixing bolt (910) placed at the edge of the second display module (510-2), in one direction to adjust the height of the second display module (510-2) to match the height of the first display module (510-1).

[0092] Referring to FIG. 12 (b), it can be seen that the first display module (510-1) and the second display module (510-2) are aligned by the step difference adjustment described above to form a uniform surface.

[0093] In this way, the height difference between the display modules (510) can be adjusted through simple operation to create a flat and smooth screen.

[0094] FIG. 13 shows a dome structure for a display according to another embodiment of the present invention, and FIG. 14 shows the components constituting the dome structure for a display of FIG. 13 separated. FIG. 15 shows an enlarged view of the display illustrated in FIG. 14. Hereinafter, redundant content described above will be omitted as much as possible.

[0095] Referring to FIGS. 13 and 14, in another embodiment, the display (500) of the dome structure (100) for display is mounted on the front (inside) of the cabinet (400) and may include a plurality of display modules (510) arranged in a spherical shape corresponding to the dome shape, and may have a structure in which a first pole area (501) and a second pole area (502) are formed on each side of the base (503) based on the central meridian (X, see FIG. 15) of the sphere. The display (500) may include, for example, one or more of an LED display, an OLED display, a micro LED display, and a hybrid display.

[0096] Conventional dome structures have a pole area formed in the center of the dome, which overlaps with the audience's field of view, and seams or connections are exposed during video projection, which can hinder immersion in the video.

[0097] On the other hand, in an embodiment of the present invention, a first pole area (501) and a second pole area (502) are formed at each end of the base (503) based on the central meridian (X) of the spherical surface of the display (500) passing through the apex of the dome, thereby increasing the sense of immersion when viewing images.

[0098] A module fixing bolt (910) described above, which is provided on the rear of a display module (510) to adjust the height difference between display modules (510) and is screw-coupled to a coupling groove of a cabinet (400) to fix the display module (510) to the cabinet (400), and an adjustment screw (920), which is screw-coupled to the module fixing bolt (910) inserted inside and is in close contact with the cabinet (400), and raises or lowers the height of the display module (510) according to the direction of rotation, may be applied. Specific details regarding the module fixing bolt (910) and the adjustment screw (920) are described in detail in FIG. 12 and are therefore omitted.

[0099] While the display (500) has a structure in which a first pole area (501) and a second pole area (502) are formed on both sides based on the central meridian (X) of the sphere, the main frame (200) may form a spherical dome outer surface and may be a radial truss structure in which a pole area (P1) is formed in the central part. The meridian frame (220) and the parallel frame (230) of the main frame (200) may be arranged radially based on the pole area (P1).

[0100] And, the subframe (300) is coupled to the inner side of the mainframe (200) and includes a longitudinal frame (310) and a transverse frame (320) arranged according to the installation spacing of the cabinet (400). The longitudinal frame (310) can form a meridian in the direction of longitude, and the transverse frame (320) can form a latitude in the direction of latitude.

[0101] The first position adjustment unit (700) described above may be used to adjust (align) the position of the subframe (300) that is coupled to the main frame (200). The first position adjustment unit (700) causes the subframe (300) to be aligned to a set position (set position) in the up-down, left-right, and front-back directions and coupled to the main frame (200). Detailed information regarding the first position adjustment unit (700) has been described in FIGS. 7 and FIGS. 8, so it is omitted.

[0102] The subframe (300) has pole areas (P2, P3) at positions corresponding to both the first pole area (501) and the second pole area (502) of the display (500), and may have a structure in which a longitudinal frame (310) and a transverse frame (320) are radially arranged based on the pole areas (P2, P3) of the subframe (300).

[0103] Cabinets (400) are each mounted at a set position of the subframe (300) and are manufactured to fit the curvature and size of the set position where they are mounted.

[0104] The second position adjustment unit (800) described above may be used to adjust the position of the cabinet (400) that is coupled to the front (inner) side of the subframe (300). The second position adjustment unit (800) aligns the cabinet (400) in the correct position in the left-right, up-down, and front-back directions so that it is coupled to the subframe (300). Detailed information regarding the second position adjustment unit (800) has been described in FIGS. 9 and FIGS. 10, so it is omitted.

[0105] As the longitudinal frame (310) and the transverse frame (320) are arranged radially based on the pole areas (P2, P3) of the subframe (300), the cabinet (400) mounted on the front (inside) of the subframe (300) also forms pole areas (P2-1, P3-1) at positions corresponding to the pole areas (P2, P3) of the subframe (300).

[0106] As illustrated in FIG. 15, a trapezoidal display module (510a) of a relatively large size compared to other areas may be placed at the spherical center of the display (500).

[0107] That is, since the curvature change is relatively gentle and the installation area is large at the center of the spherical surface of the display (500), the display module (510a) in that area can be manufactured and placed in a relatively large trapezoidal shape.

[0108] The display module (510a) positioned at the spherical center of the display (500) can have a relatively high resolution compared to the display module in other areas.

[0109] In this way, high-resolution display modules (510a) can be concentrated on the spherical center side of the display (500) to increase the satisfaction of the audience.

[0110] In the first pole area (501) and the second pole area (502) and the adjacent periphery, a display module (510b) with a triangular or trapezoidal shape that is relatively smaller than other areas may be placed.

[0111] That is, the first pole area (501) and the second pole area (502) of the display (500) are areas where the curvature of the spherical surface changes rapidly, and the space where the display module can be placed is relatively limited.

[0112] Accordingly, display modules can be manufactured in a relatively small triangular or trapezoidal shape and densely arranged in the first pole area (501) and the second pole area (502) and the adjacent periphery.

[0113] The first pole area (501) and the second pole area (502) and the display (510b) placed in the adjacent periphery may have a relatively lower resolution compared to the display module in other areas.

[0114] In this way, low-resolution display modules can be placed in the first pole area (501), the second pole area (502), and the adjacent periphery to optimize resource utilization.

[0115] Through the embodiments of the present invention described above, structural stability can be provided by designing a multi-layer frame structure to firmly support the entire dome load without relying on external structures.

[0116] In addition, alignment and a uniform surface between display modules can be achieved with simple operation, and the height, inclination, and step difference between the frame and modules constituting the dome structure can be efficiently adjusted.

[0117] In addition, it can provide the audience with an immersive video viewing experience.

[0118] As described above, preferred embodiments of the present invention have been illustrated and described with reference to the drawings; however, the present invention is not limited to the specific embodiments described above. Furthermore, various modifications can be made by those skilled in the art without departing from the essence of the invention as claimed in the patent claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
