[0011] The present invention will be described below with reference to the drawings based on embodiments thereof. Note that the present invention is not limited to the following embodiments. Furthermore, the drawings referred to in the following description merely show the shapes, sizes, and positional relationships in a schematic manner to enable understanding of the contents of the present disclosure. In other words, the present invention is not limited to only the shapes, sizes, and positional relationships exemplified in the drawings.

[0012] <Large-screen display system overview> First, an overview of a large-screen display system according to one embodiment of the present invention will be described. FIGS. 1A and 1B are front views schematically showing an indoor space in which a large-screen display system according to this embodiment is installed. The large-screen display system 1 of this embodiment includes four sets of display panels 10A to 10D. The display panels 10A to 10D each have the same configuration, with display screens 11A to 11D formed by a plurality of LED panels P. When referring to the display panels individually without making a distinction, they will simply be referred to as display panel 10 and display screen 11.

[0013] 1A and 1B, the display panels 10A to 10D can be moved to any position within the indoor space 1000 along rails installed along the wall 1100 of the indoor space 1000. A cylindrical slider 12 is engaged with the rails so as to enable the display panel 10 to slide along the rails. An example of the configuration of the rails for movement will be described later.

[0014] In the example of Fig. 1A, display panels 10B and 10C are arranged adjacent to each other in the center, and display panels 10A and 10D are arranged on either side of them, spaced apart. Each of the display panels 10A-10D is communicably connected to a control unit that controls the display of the large-screen display system 1 via a connection unit (described later). In the example of Fig. 1A, a desired image can be displayed on each of the display panels 10A-10D based on a display control signal transmitted from the control unit. For example, the central display panels 10B and 10C can be operated as a single large display screen to display an image, while the left and right display panels 10A and 10D can each display separate images as auxiliary images.

[0015] 1B, four sets of display panels 10A to 10D are arranged adjacent to each other in the center to form one huge display screen 11A to 11D. In this case, too, based on a display control signal from the control unit, it is possible to display a large image on the one display screen or to display individual images on each of the display panels 10A to 10D.

[0016] <<About the display panel 10>> Here, each display panel 10 will be described with reference to Figures 1A to 2B. Figure 2A is a front view illustrating display panel 10, and Figure 2B is a side view thereof. As shown, display panel 10 has a substrate 15 formed by providing an exterior material such as a resin sheet on steel frame members arranged in a lattice pattern, and a display screen 11 formed by arranging and fixing a plurality of LED panels P in a rectangular shape on substrate 15. Note that when the display screens 11 provided on display panels 10A to 10D are to be distinguished from one another, they will be referred to as display screens 11A to 11D.

[0017] The LED panel P is a display device consisting of a large number of LED elements arranged two-dimensionally in a grid pattern on a rectangular substrate. The arrangement pitch of the LED elements can be determined according to the expected viewing distance of the display screen that constitutes it. For example, in the present embodiment, when the display screen 11 is to be viewed from a relatively close distance, such as in a hotel ballroom, the LED elements can be arranged at a pitch of approximately 1.5 mm. The performance of the LED elements, such as brightness and viewing angle, is determined according to the usage environment, the required specifications of the application, etc.

[0018] The display panel 10 of this embodiment has a substrate 15 with dimensions of approximately 5,600 mm in height, 3,000 mm in width, and 150 mm in thickness. A total of 50 LED panels P (five horizontally and ten vertically) are attached to the vertical center of the substrate 15, forming a large display screen 11 with a height of approximately 3,500 mm and a width of approximately 3,000 mm. Note that suitable self-emitting elements other than LED elements may also be used as the light-emitting elements. Alternatively, if conditions are suitable, a display device using non-self-emitting elements such as a liquid crystal panel may also be used. The shape and dimensions of the display panel 10 and the display screen 11 can be modified depending on the intended application, required specifications, etc.

[0019] The LED panels P that make up the display screen 11 can individually control the display content of each LED panel P, as a minimum unit. Alternatively, the LED panels P can be divided into multiple groups on the display screen 11, and the display content can be controlled for each group. It is also possible to control the display of the entire display screen 11, which is a collection of the display panels P, as a single screen, or to combine the display screens 11 of multiple display panels 10 and control them as a single larger display screen. In this embodiment, two sets of display panels 10 are arranged side by side to form a 16:9 screen with a screen size of approximately 280 inches. Four sets of display panels 10 are arranged side by side to form a 32:9 screen with a screen size of approximately 500 inches.

[0020] <<About moving the display panel 10>> Movement of the display panel 10 in the large-screen display system 1 of this embodiment will now be described. FIG. 3 is a schematic plan view of an indoor space 1000 in which the large-screen display system 1 is installed. For ease of understanding, FIG. 3 illustrates the indoor space 1000, such as a hotel ballroom, from above, as seen through the ceiling. As shown in FIGS. 2A and 2B, sliders 12 are provided at multiple locations on the top of the substrate 15 of each display panel 10 for moving the display panel 10 within the indoor space 1000. Meanwhile, rails R1 are provided on the ceiling of the indoor space 1000, running along the wall surfaces 1100 of the indoor space 1000. In FIG. 3, the rails R1 are indicated by dashed lines. The display panel 10 is suspended and slidable by sliders 12 fitted to the rails R1, which have a cross section similar to a curtain rail mounted on the ceiling surface, and as illustrated in Fig. 3, forms a roughly U-shaped movement path along the left and right sides of the indoor space 1000 as viewed from the page, and along the lower wall surface 1100. The rail R1 on the right side of the page in Fig. 3 extends into a storage space ST provided adjacent to the indoor space 1000, and the display panel 10 moved downward along the right rail R1 is sequentially stored in the storage space ST along a pair of parallel rails R1 within the storage space ST. As described above, each slider 12 provided at the top of the display panel 10 is fitted to the rails R1, thereby suspending the display panel 10 from the ceiling and supporting it movably along the rails R1.

[0021] The indoor space 1000 is provided with a partition panel 1200, along with the display panel 10, for dividing the indoor space 1000 into multiple independent spaces. The partition panel 1200 is stored in the storage space ST together with the display panel 10 and is moved along a rail R2 for partitioning. Although not shown, a support member equivalent to the slider 12 of the display panel 10 is also provided at the top of the partition panel 1200, and can be moved along the rail R2. In FIG. 3, the rail R2 is indicated by a two-dot chain line. The partition panel 1200 is provided vertically in the center of the indoor space 1000 in FIG. 3, and a rail R2 is provided extending leftward from the middle and joining the rail R1. By moving the partition panel 1200 along the rail R2, the indoor space 1000 can be divided into two sections, left and right, and can also be further divided into three sections for use.

[0022] By installing such display panels 10, the display panels 10 can be arranged in any combination at any position along the rail R1 within the indoor space 1000. Furthermore, even if the indoor space 1000 is divided into multiple sections by partition panels 1200, by arranging the display panels 10 in each section as desired, it is possible to provide image display on the display screen 11 according to the needs of each section.

[0023] <<Screen display control for large-screen display system 1>> Next, we will explain the screen display control of the large-screen display system 1 according to this embodiment. Fig. 4 is a block diagram illustrating the overall configuration of the large-screen display system 1. The large-screen display system 1 includes a control unit 100 that controls the video display of each display screen 11, an operation terminal 300 that allows the control unit 100 to set the layout of each display screen 11 and to operate the display pattern of display control signals for the arranged display screens 11, a personal computer (PC) 220 that supplies content video data that is the source of the display control signals to the control unit 100, input devices such as a camera 230 and various media players 240 for DVDs, Blu-ray discs, etc., an input switching unit 210 that switches the input signals from the various input devices to the control unit 100, and a distribution unit 160 that distributes the display control signals output from the control unit 100 to each display panel 10 according to the settings.

[0024] The display control signal output from the distribution unit 160 is supplied via the connection unit 20 to the LED panel P that constitutes the display screen 11 of each display panel 10 in accordance with the layout setting of the display screen 11. The specific configuration of each unit will be described below along with the flow from the signal input side to the output side.

[0025] The input devices, PC 220, camera 230, and media player 240, are devices that provide video data as material to be displayed on the display screen 11 of the display panel 10. Video data of various formats stored on a storage disk or the like of the PC 220, video data including video captured by the camera 230, video data stored on various media such as DVDs and Blu-ray discs, etc., can be input to the input switching unit 210. Other inputs include video streaming data received via a communication network such as the Internet. Data other than moving images, such as still images, can also be input. The above input devices are mounted on a movable wagon or the like to form an input unit 200. In this way, the input devices can be moved as needed within the indoor space 1000. Two or more input units 200 may be provided.

[0026] The input switching unit 210 has a function of selectively switching input signals from various connected input devices and outputting the signals to the control unit 100. Specifically, the input switching unit 210 is configured as hardware such as a digital switcher.

[0027] The operation terminal 300 is a terminal device for inputting instructions to the control unit 100 regarding the control content of the control unit 100, including the layout pattern of the display panels 10 and the pattern of display control signal output to the display screen 11 of each display panel, and is embodied as hardware such as a tablet terminal on which application software required for operating the control unit 100 is installed. In the example of Fig. 4, it is assumed that software functioning as an operation setting unit 310 is installed in the operation terminal 300. Examples of operations using the operation terminal 300 will be described later.

[0028] The control unit 100 controls the data distribution output in the distribution unit 160, which will be described later, based on the layout setting of the display panel 10 from the operation terminal 300 and the data output setting to the display screen 11. The control unit 100 includes a processor 110 such as a CPU or MPU that executes data processing based on a control program, a memory 120 configured with RAM, ROM, etc. that provides a work area for the program executed by the processor 110 and a storage area for the data to be used, a storage 130 configured with a hard disk, semiconductor disk, etc. that is used as a storage area for the program, a communication unit 140 configured as a communication module that is used for communication with the operation terminal 300, other communication terminals such as smartphones, or communication networks such as the Internet or LAN, and a data input / output unit 150 that manages the input and output of data to and from the distribution unit 160.

[0029] The distribution unit 160 distributes and outputs display data to the LED panels P that make up the display screen 11 of each display panel 10 under the control of the processor 110. Specifically, the distribution unit 160 is embodied as a matrix switcher that manages the output ports of the video signals under the control of the processor 110.

[0030] The display control signal output from the distribution unit 160 is transmitted to the connection unit 20, which serves as a signal relay point for each display panel 10. In this embodiment, the output signal from the distribution unit 160 is converted from an electrical signal to an optical signal by an optical converter (not shown) and transmitted to the destination connection unit 20. This optical signal is received from the destination connection unit 20 by an optical converter of the display panel 10, which is connected to the connection unit 20 by a cable, and converted from an optical signal to an electrical signal. The display control signal, now an electrical signal, is input to a display control driver of the LED panel P that constitutes the display screen 11 of the display panel 10, and displays and outputs an image through light emission control of the LED elements of each LED panel P. A plurality of connection units 20 are arranged on the wall and floor of the indoor space 1000 along the rail R1 of the indoor space 1000. Specifically, they are installed at multiple locations along the rail R1 where the display panels 10 are expected to be arranged. Each connection unit 20 includes an optical connector for transmitting and receiving an optical signal of a display control signal, and a power outlet (for example, AC 220V, AC 100V, etc.) for supplying drive power and control power to each LED panel P.

[0031] With this configuration, the display panel 10 can be moved along the rail R1 and placed at any position in the indoor space 1000, and by connecting a cable for receiving display control signals and power to the connection part 20 provided on a nearby wall or floor, it is possible to display and output images according to the combination of the division of the indoor space 1000 and the display panel 10.

[0032] Fig. 5 shows functional blocks realized by the processor 110 of the control unit 100. The processor 110 realizes each function shown in Fig. 5 by reading and executing a program stored in the storage 130. However, some or all of these functions may be realized by hardware.

[0033] The panel layout setting unit 111 sets the layout of the display panels 10 in the indoor space 1000 such as a ballroom based on a setting input from the operation setting unit 310 of the operation terminal 300 .

[0034] The display control signal generation unit 112 has a function of generating a display control signal to be supplied to the LED panel P included in each display panel 10, based on a video signal input from the input switching unit 210 of the input unit 200.

[0035] The display output switching unit 113 has a function of transmitting the display control signal generated by the display control signal generation unit 112 to the LED panel P of the display panel 10 designated as the destination, in accordance with the arrangement of the display panel 10 determined by the panel arrangement setting unit 111. Specifically, the display output switching unit 113 is, for example, a program for realizing signal input-output routing in a matrix switcher constituting the distribution unit 160. The routing of the display control signal determines to which connection unit 20 a video signal input from the input switching unit 210 of the input unit 200 to the control unit 100 should be supplied.

[0036] The data input / output unit 114 is a data interface that manages the processing of video signal input from the input unit 200, display panel 10 layout setting input from the operation terminal 300, video signal display pattern setting input, and output of display control signals to the display panel 10.

[0037] Based on the data processing performed by these control units 100, a display control signal for the LED panel P is generated based on the video signal from the input unit 200, and video display on each display panel 10 is performed according to the arrangement of the display panels 10 set on the operation terminal 300 and the display pattern on the display screen 11 of each display panel 10.

[0038] <<Layout and display pattern of the display panel 10>> 6A to 6C, the layout and display pattern settings of the display panel 10 in the operation terminal 300 will be described. FIGS. 6A to 6C show examples of display setting screens displayed by the operation setting unit 310 in the operation terminal 300. In each example screen, reference numeral 311 denotes a setting input unit for setting the layout of the display panel 10, and reference numeral 312 denotes a setting input unit for setting the display pattern for the layout setting of the set display panel 10.

[0039] The display panel arrangement setting input unit 311 allows the user to select how to combine the four sets of display panels 10A to 10D in this embodiment to form a display screen. Six combinations are preset in the setting screen examples shown in FIGS. 6A to 6C. In the illustrated example, each display panel 10 is identified by symbols A to D. When the symbols "A / B" are combined with a slash, A and B are displayed separately. On the other hand, when the symbols "A+B" are combined with a plus sign, A and B are displayed adjacent to each other as a single display screen. The number of display panels 10 can be expanded to 10 or more sets, as needed.

[0040] Regarding the display pattern setting unit 312, a plurality of patterns for how images are displayed on each display panel 10 are prepared according to the selection made by the layout setting unit 311. For the display screen 11 of each display panel 10, A pattern displayed in the vertical center of the display screen 11 A pattern in which the upper and lower halves of the display screen 11 are divided to display different images. A pattern in which the image is displayed in the center of the display screen 11 in the vertical direction, using only the left half or the right half of the screen in the width direction. However, as mentioned above, since the display screen 11 of each display panel 10 is made up of 50 LED panels P, it is possible to display in a pattern different from the above by changing the distribution control of the display control signal from the control unit 100.

[0041] In the example screen of FIG. 6A, "A / B / C" is selected as the arrangement of display panels 10. This indicates a configuration in which display panels 10A, 10B, and 10C are used independently for display, and display panel 10D is not used. In this case, ten display patterns, No. 1 to No. 10, are preset in display pattern setting unit 312. For example, when No. 1 is selected, control is exercised so that separate images are displayed in the vertical center of each display screen 11 of display panels 10A, 10B, and 10C. Furthermore, when No. 8 is selected, for example, an image is displayed only in the left half of the vertical center of display screen 11 for display panels 10A and 10B, and for display panel 10C, the display screen 11 is divided into upper and lower halves and separate images are displayed in each halves.

[0042] In the example screen shown in FIG. 6B, "A / B+C+D" is selected as the layout of the display panels 10. This indicates a configuration in which only display panel 10A is independent, while display panels 10B to 10D are adjacent to one another to form a single screen. In this case, seven display patterns, No. 26 to No. 31 and No. 32, are preset in the display pattern setting unit 312. For example, when No. 30 is selected, the display screen 11A of display panel 10A is split into two parts, one above the other, and display panels 10B to 10D form a single display screen 11. Another image is displayed in the central area of ​​the screen, split into two parts, left and right. In the case of No. 32, a high-resolution 4K image is displayed using the display pattern shown in the figure.

[0043] In the example screen of FIG. 6C, "A+B / C+D" is selected as the arrangement of the display panels 10. This indicates a configuration in which display panels 10A and 10B and display panels 10C and 10D are used as a set to form two relatively large screens. In this case, four display patterns, No. 33 to No. 35, and No. 36, are preset in the display pattern setting unit 312. For example, when No. 33 is selected, the display screens 11 of the display panels 10A and 10B are split horizontally into two parts in the vertical center, and the display screens of the display panels 10C and 10D are set to be used as a single display screen 11 in their entirety. In the case of No. 36, a high-resolution 4K image is displayed using the display pattern shown in the figure.

[0044] In this way, according to the operation terminal 300 of this embodiment, a large number of combination arrangements of the display panels 10 and display patterns for those arrangements are preset in advance, so the user can intuitively and quickly set the display screen without making any mistakes while looking at the screen of the operation setting unit 310.

[0045] <<How to use the large screen display system 1>> Next, we will explain how to operate the large-screen display system 1 according to this embodiment. Fig. 7 shows a flowchart illustrating an example of how to operate the large-screen display system 1 according to this embodiment. The flowchart in Fig. 7 provides an overview of the series of steps from preparing the components of the large-screen display system 1 to displaying images with the desired screen layout and display pattern, all the way to completion. Note that the symbol S in the diagram represents a step.

[0046] When operation begins in step S1, first, in step S2, a desired number of display panels 10 are carried out from storage space ST in indoor space 1000, such as a hotel ballroom, and moved to desired positions along rails R1. This movement of the display panels 10 is performed manually by about two people, but as an extension of this embodiment, it is also possible to mechanize the movement by providing a drive mechanism, such as an electric roller, on the display panels 10 or the rails R1.

[0047] In step S3, the display panel 10 that has been moved to the predetermined position is connected to the connection unit 20 that is arranged near the rail R1. Specifically, an optical cable for transmitting a display control signal and a power cable for driving and controlling the LED elements of the LED panel P are connected from the connection unit 20 to the LED panel P of the display panel 10.

[0048] In step S4, the arrangement of the display panels 10 and the pattern of image display on the display screen 11 are set in the operation setting unit 310 of the operation terminal 300 based on the arrangement of the display panels 10 in the indoor space 1000 and the desired display pattern.

[0049] In step S5, a video signal is supplied from a desired input device of the input unit 200 to the control unit 100, and an image is displayed in the set display pattern on the display screen 11. Depending on the arrangement of the display panel 10 and the setting of the display pattern in step S4, the video signal input from the input unit 200 to the control unit 100 via the input switching unit 210 is converted into a display control signal and supplied to the LED panel P of the display panel 10, which is the display destination, based on the setting.

[0050] In step S6, after all image displays on the display panels 10 have been completed, the cables between each display panel 10 and the connection unit 20 are disconnected. Then, in step S7, each display panel 10 is moved along the rail R1 and stored in the storage space ST in the indoor space 1000, thereby completing the series of operations (step S8).

[0051] According to the above-described method of operating the large-screen display system 1, display panels can be arranged in an indoor space 1000 such as a hotel ballroom in accordance with its variable layout, and by simply setting the image display pattern corresponding to that arrangement, the large-screen display system 1 can be set up quickly and without error, and effective image display according to the purpose can be provided.

[0052] <<Example of display panel 10 arrangement>> Here, we will explain an example of the arrangement of display panels 10 when operating the large-screen display system 1 in an indoor space 1000. A large indoor space 1000 such as a hotel ballroom can be used not only as a single venue as a whole, but also divided into two or more sections by partition panels 1200 depending on the purpose, scale, etc. Even in such cases, the large-screen display system 1 of this embodiment can arrange multiple display panels 10 in each section in a variety of ways, thereby providing effective video display that corresponds to the purpose, scale, etc. of the event in each section.

[0053] 8A and 8B show examples of display panel arrangements 10 when the layout of the indoor space 1000 illustrated in FIG. 3 is changed. In the example of FIG. 8A, the entire indoor space 1000 is used for a lecture-style seminar.
