[0036] Since the present disclosure can be variously modified and has several embodiments, specific non-limiting example embodiments of the present disclosure will be shown in the drawings and described in detail in the detailed description. However, it should be understood that the present disclosure is not limited to the specific embodiments described below, but includes various modifications, equivalents, and / or alternatives of the embodiments of the present disclosure. Regarding the description of the drawings, similar reference numerals may be used for similar components.

[0037] If it is determined that a detailed description of related known technologies may unnecessarily obscure the gist of the present disclosure when describing the embodiments, the detailed description will be omitted.

[0038] The following embodiments can be modified in many different forms, and the scope of the technical spirit of the present disclosure is not limited to the following examples. In fact, these embodiments are provided so that the present disclosure will be comprehensive and complete, and the technical spirit will be fully conveyed to those skilled in the art.

[0039] The terms used in this document are used to describe certain embodiments and are not intended to limit the scope of the claims. Unless otherwise specified, singular expressions include plural expressions.

[0040] In this specification, expressions such as “has,” “may have,” “includes,” or “may include” indicate the presence of corresponding features (e.g., components such as numbers, functions, operations, or parts), and do not exclude the presence of additional features.

[0041] In this document, expressions such as “at least one of A [and / or] B” or “one or more of A [and / or] B” include all possible combinations of the listed items. For example, “at least one of A and B” or “at least one of A or B” includes any one of the following: (1) only A, (2) only B, or (3) both A and B.

[0042] The terms “first,” “second,” etc. used in this document may represent various components regardless of order and / or importance, and may be used to distinguish one component from another without limiting these components.

[0043] If it is described that a certain element (e.g., the first element) is “operatively or communicatively coupled to” / “operatively or communicatively coupled with” another element (e.g., the second element), or “connected to” another element (e.g., the second element), it should be understood that the certain element may be directly connected to or connected to the other element through other elements (e.g., the third element).

[0044] On the other hand, if it is described that a certain element (e.g., the first element) is “directly coupled to” or “directly connected to” another element (e.g., the second element), it can be understood that there is no element (e.g., the third element) between the certain element and the other element.

[0045] In addition, the expression “configured to” used in this disclosure may be interchangeably used with other expressions such as “suitable for,” “capable of,” “designed to,” “adapted to,” “manufactured to,” and “able to” depending on the context. However, the term “configured to” does not necessarily mean that the device is “specially designed” in terms of hardware.

[0046] On the contrary, in some cases, the expression “a device configured to...” may mean that the device “is capable of” performing operations together with another device or component. For example, the phrase “a processor configured to execute A, B, and C” may mean a dedicated processor (e.g., an embedded processor) for executing corresponding operations, or a general-purpose processor (e.g., a central processing unit (CPU) or an application processor) that can execute the corresponding operations by executing one or more software programs stored in a storage device.

[0047] Terms such as "module", "unit", "component", etc. are used to refer to elements that perform at least one function or operation, and such elements can be implemented as hardware or software, or a combination of hardware and software. In addition, components can be integrated in at least one module or chip and implemented in at least one processor, except when each of multiple "modules", "units", "components", etc. needs to be implemented in separate hardware.

[0048] The various elements and regions in the figures are not shown to scale. Therefore, the scope of the present disclosure is not limited by the relative sizes or spacings drawn in the figures.

[0049] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings, so that those skilled in the art to which the present disclosure pertains can easily manufacture and use the embodiments.

[0050] Figure 1 is a diagram of an example display system including a modular display device and a source device. Figure 2 is a diagram of an example display system including a plurality of modular display devices and a plurality of source devices respectively connected to the plurality of modular display devices.

[0051] In Figure 1 , the display system 1000 includes a modular display device 200 and a source device 100. Here, the modular display device 200 and the source device 100 can be connected through a communication interface 120, and the source device 100 can send image data to the modular display device 200. The modular display device 200 displays an image based on the received image data.

[0052] When the display system 1000 includes the modular display device 200 and the source device 100, since the modular display device 200 for displaying an image and the source device 100 for sending image data related to the image displayed on the modular display device 200 or sending control commands are connected to each other to perform corresponding functions, it is important to accurately identify the paired or matching source device 100 and modular display device 200.

[0053] This is because when the user incorrectly identifies the source device 100 connected to the modular display device 200 and manipulates another source device connected to another modular display device (for example, when inputting a control command for adjusting the brightness or volume of the modular display device 200 through the source device 100), the operating state (such as brightness or volume) of another modular display device rather than the modular display device 200 expected by the user may be changed.

[0054] This problem may often occur when the display system 1000 includes a plurality of source devices 100 and a plurality of modular display devices 200, and the plurality of source devices 100 and the plurality of modular display devices 200 are located in different separate spaces.

[0055] In Figure 2 it, the display system 1000 may include three source devices (a first source device 100-1, a second source device 100-2, and a third source device 100-3) and three modular display devices 200-1, 200-2, 200-3 respectively connected to the three source devices (the first source device 100-1, the second source device 100-2, and the third source device 100-3). At this time, different from the three modular display devices 200-1, 200-2, and 200-3 separately provided in different spaces 1, 2, and 3, the three source devices (the first source device 100-1, the second source device 100-2, and the third source device 100-3) may be provided in the same space 4. For example, the three source devices (the first source device 100-1, the second source device 100-2, and the third source device 100-3) may be provided together in a control room, a control station, etc.

[0056] In one embodiment, each of the modular display devices 200-1, 200-2, 200-3 may be arranged in a space separate from the source device (the first source device 100-1, the second source device 100-2, and the third source device 100-3) connected to the corresponding modular display device 200-1, 200-2, 200-3. Therefore, in order to control the operation (e.g., brightness and volume control, etc.) of a specific modular display device among the plurality of modular display devices 200-1, 200-2, 200-3, in the space where the plurality of source devices 100 are arranged, it is necessary to accurately identify the process of the specific source device among the plurality of source devices 100 that is connected to the specific modular display device.

[0057] This is because when the source device connected to the modular display device to be controlled by the user is inaccurately identified as another source device (i.e., another source device connected to another modular display device), failures may occur, such as changing the image displayed on another modular display device rather than the modular display device expected by the user by manipulating another source device, or changing the brightness or volume of another modular display device.

[0058] To this end, in the related art, tags, stickers, etc. for identifying modular display devices connected to each source device are attached to each source device. However, during the labeling process (i.e., the process of attaching tags, stickers, etc. to the modular display device), it may be difficult to accurately identify the source device connected to each modular display device when an incorrect tag (or sticker) is attached or the attached tag (or sticker) is damaged or lost. If the optical cable 300 connected to a specific modular display device and a specific source device is traced from a specific modular display device, the specific source device can be accurately identified, but when the distance between the space where the modular display device is set and the space where the source device is set is very far, it may take a lot of time.

[0059] The display system 1000 according to one or more embodiments solves this task. More specifically, without a separate labeling process for the source device, the display system 1000 directly identifies the source device connected to the modular display device. Hereinafter, embodiments related thereto will be described.

[0060] Figure 3 is a configuration diagram of a display system 1000 according to one or more embodiments of the present disclosure, Figure 4 is a configuration diagram of a source device 100 included in a display system 1000 according to one or more embodiments of the present disclosure.

[0061] The display system 1000 according to one or more embodiments includes a plurality of source devices 100 (e.g., a first source device 100-1, a second source device 100-2 to an nth source device 100-n) and a plurality of modular display devices 200 (200-1, 200-2,..., 200-n).

[0062] In one embodiment, the first source device to the nth source device (n is a natural number greater than or equal to 2) are used to distinguish different source devices included in the display system 1000, and the first source device to the nth source device are not devices with different configurations, but share the same features. Therefore, the embodiments of the present disclosure related to the source device to be described hereinbelow are applied to the first source device to the nth source device (n is a natural number) in the same manner.

[0063] In one embodiment, the plurality of source devices 100 and the plurality of modular display devices 200 included in the display system 1000 can be connected separately. That is, in Figure 3Among them, the first source device 100-1 can be connected to the first modular display device 200-1, and the second source device 100-2 can be connected to the second modular display device 200-2. In other words, multiple modular display devices 200 can be respectively connected to different source devices 100. The embodiment is not limited thereto, and multiple source devices 100 can be connected to the same modular display device 200. This will be described in detail in Figure 10 as follows.

[0064] The source device 100 sends image data to the modular display device 200. For this purpose, the source device 100 and the modular display device 200 can be connected through an optical cable 300 or the like. In one embodiment, the source device 100 and the modular display device 200 can be connected through the optical cable 300, and data (such as image data) can be transmitted and received by an optical communication method.

[0065] Each of the source device 100 and the modular display device 200 can convert an electrical signal into an optical signal and send the signal to another device, or reconvert the optical signal received from another device into an electrical signal. Specifically, the source device 100 can convert the image data as an electrical signal into an optical signal and send the optical signal to the modular display device 200.

[0066] The embodiment is not limited thereto, and the source device 100 can send the image data to the modular display device 200 connected through the network based on a wireless communication method.

[0067] In an embodiment, the source device 100 can not only send image data to the modular display device 200, but also send various information to the modular display device 200. For example, the source device 100 can send the sound data corresponding to the image data to the modular display device 200, or can send a control command for controlling the modular display device 200 to the modular display device 200.

[0068] In an embodiment, the source device 100 can send a control command for controlling the brightness, volume, etc. of the modular display device 200 to the modular display device 200 based on a user command input through an input interface (such as a button, a touch display panel, etc.) provided on one side of the source device 100. The source device 100 can be implemented by a set-top box or the like.

[0069] The modular display device 200 receives image data from the source device 100 and displays an image based on the received image data. In an embodiment, the modular display device 200 may send a notification request signal for the source device 100 to the source device 100. Here, the notification request signal may be a signal for requesting the output of notification information to the source device 100 connected to the modular display device 200. The notification request signal may be generated by the modular display device 200 by receiving a control signal from the control device 400 that interacts with the modular display device 200.

[0070] In an embodiment, the source device that receives the notification request signal from the modular display device 200 may output identification information of the source device 100, etc. through the output interface 110 provided in the source device 100. This will be described in detail with reference to Figure 4 and Figure 7 This will be described in detail.

[0071] In Figure 4 According to one or more embodiments of the present disclosure, the source device 100 includes an output interface 110, a communication interface 120, and one or more processors 130.

[0072] The output interface 110 may output various information related to the source device 100. For example, when the source device 100 receives a notification request signal for the source device 100 from the modular display device 200 connected to the source device 100, the output interface 110 may output notification information. To this end, the output interface 110 may be implemented in various forms, such as at least one LED light-emitting element, a speaker, a display panel, etc.

[0073] The communication interface 120 may be connected to the modular display device 200 and may send various information to the modular display device 200 and receive various information from the modular display device 200. For example, the communication interface 120 may send various information such as image data, sound data, and control commands to the modular display device 200. In addition, the communication interface 120 may receive a notification information request signal from the modular display device 200.

[0074] In an embodiment, the communication interface 120 may communicate with the modular display device 200 based on multiple communication modules using different communication methods. For example, the communication interface 120 may use an optical cable 300 to send information (e.g., image data, sound data, and control commands) required to drive the modular display device 200 by using an optical communication method, and may receive a notification request signal by using a wireless communication method.

[0075] Specifically, the source device 100 may separately include a communication module for sending image data to the modular display device 200 and a communication module for receiving a notification information request signal. For example, the communication interface 120 may include a Small Form-factor Pluggable (SFP) module. At this time, the source device 100 may be connected to one end of the optical cable 300 connected to the modular display device 200 through the SFP module. The source device 100 may convert electrical signals such as image data, sound data, and control commands into optical signals through the SFP module included in the communication interface 120, and then may send the optical signals to the modular display device 200 through the optical cable 300.

[0076] The communication interface 120 may include a wireless communication module. At this time, the source device 100 may receive a notification request signal from the modular display device 200 through the wireless communication module. The wireless communication method may include Wi-Fi, Wi-Fi Direct, Ultra-Wideband (UWB), Zigbee, Infrared Data Association (IrDA), 3GPP, Wi-Max, Long-Term Evolution (LTE), 5G, etc.

[0077] One or more processors 130 control the overall operation of the source device 100. Specifically, one or more processors 130 may be connected to the output interface 110 and the communication interface 120 of the source device 100, and may control the overall operation of the source device 100.

[0078] The processor 130 according to one or more embodiments may be named various names, such as a Digital Signal Processor (DSP), a microprocessor, a Central Processing Unit (CPU), a Microcontroller Unit (MCU), a Micro Processing Unit (MPU), a Neural Processing Unit (NPU), a controller, an Application Processor (AP), a Timing Controller (TCON), but the term one or more processors 130 will be used here.

[0079] In an embodiment, one or more processors 130 may be implemented in a System-on-Chip (SoC) type, or a Large Scale Integration (LSI) type, or a Field Programmable Gate Array (FPGA) type. In one embodiment, one or more processors 130 may include volatile memory such as SRAM, etc.

[0080] Hereinafter, for ease of description, one or more processors 130 are referred to as the processor 130.

[0081] Figure 5 is a diagram showing a first modular display device 200-1 among a plurality of modular display devices 200 (included in the display system 1000) according to an embodiment of the present disclosure, and Figure 6FIG. is a diagram showing the configuration of a first modular display device 200-1 among a plurality of modular display devices 200 (included in the display system 1000) according to an embodiment of the present disclosure. In Figure 5 and Figure 6 the first modular display device 200-1 is merely an example. The first modular display device 200-1 may be replaced with other modular display devices (e.g., the second modular display device 200-2, the third modular display device 200-3, and the fourth modular display device 200-4).

[0082] In one embodiment, Figure 3 the first modular display device to the nth modular display device (n is a natural number greater than or equal to 2) shown are used to distinguish different modular display devices included in the display system 1000, and the first source device to the nth source device are not devices with different configurations but share the same features. Therefore, the embodiments of the present disclosure for the modular display device described below equally apply to Figure 3 the first modular display device to the nth modular display device (n is a natural number) shown.

[0083] In Figure 6 the first modular display device 200-1 according to one or more embodiments includes a plurality of cabinets 210 (210-1, 210-2,..., 210-n, where n is a natural number of 2 or greater), a communication interface 220, and one or more processors 230.

[0084] The first modular display device 200-1 may include a plurality of cabinets 210. In this case, the first modular display device 200-1 may be implemented as a large display device (e.g., a digital sign, an electronic display, etc.) or a small display device (e.g., a monitor for a personal computer, a TV, etc.) in which a plurality of cabinets including a plurality of display modules are coupled or assembled, but is not limited thereto.

[0085] The plurality of cabinets are arranged in a matrix format and constitute the first modular display device 200-1. For example, in Figure 5 if the modular display device 200 includes four cabinets 210-1, 210-2, 210-3, and 210-4, the four cabinets 210-1, 210-2, 210-3, and 210-4 may be arranged in a 2×2 format and implement the first modular display device 200-1.

[0086] At this time, the first modular display device 200-1 outputs an image through a plurality of cabinets 210 that make up the first modular display device 200-1. In one embodiment, when each cabinet 210 is coupled according to a preset layout format, the first modular display device 200-1 can output a specific image through the entire screen achieved when coupling the display panels of the plurality of display modules included in each cabinet 210. Each cabinet 210 outputs a part of the specific image.

[0087] In an embodiment, due to coupling various numbers of cabinets 210, the first modular display device 200-1 can have different sizes or different resolutions. In one embodiment, in order to implement the first modular display device 200-1, the plurality of cabinets 210 can be arranged in various matrix formats other than Figure 5 the 2×2 matrix format shown. That is, according to one or more embodiments of the present disclosure, the plurality of cabinets 210 can be arranged in an M×L matrix format (where M and L are natural numbers equal to or greater than 1). The cabinets can be referred to as "sub-screens" and "display devices".

[0088] The communication interface 220 can be connected to the source device 100, and can send various information to the source device 100 and receive various information from the source device 100. For example, the communication interface 220 can receive various information such as image data, sound data, and control commands from the source device 100. In an embodiment, the communication interface 220 can send a notification information request signal to the source device 100. In an embodiment, the communication interface 220 can be connected to the control device 400 to receive a control signal.

[0089] The communication interface 220 can communicate with the source display device 100 based on a plurality of communication modules using different communication schemes. For example, the communication interface 220 can receive image data, sound data, control commands, etc. from the source device 100 through an optical communication method using an optical cable 300, and can send a notification request signal through a wireless communication method.

[0090] In an embodiment, the modular display device 200 can respectively include a communication module for sending image data to the source device 100 and a communication module for receiving a notification information request signal.

[0091] For example, the communication interface 220 can include a small form-factor pluggable (SFP) module. The modular display device 200 can be connected to the other end of the optical cable 300 connected to the source device 100 through the SFP module. The modular display device 200 can receive an optical signal from the source device 100 through the optical cable 300, for example, image data, sound data, and control commands converted into optical signals through the SFP module included in the communication interface 220.

[0092] The communication interface 220 may include a wireless communication module. At this time, the modular display device 200 may send a notification request signal to the source device 100 through the wireless communication module. In an embodiment, the modular display device 200 may receive a control signal of the control device 400 through the wireless communication module. The wireless communication methods may include Wi-Fi, Wi-Fi Direct, Ultra-Wideband (UWB), Zigbee, Infrared Data Association (IrDA), 3GPP, Wi-Max, Long-Term Evolution (LTE), 5G, IR, Bluetooth, etc.

[0093] One or more processors 230 control the overall operation of the modular display device 200. In an embodiment, one or more processors 230 may be connected to the communication interface 220 and the plurality of cabinets 210 of the modular display device 200, and may control the overall operation of the modular display device 200.

[0094] The processor 230 according to one or more embodiments may be named various names, such as Digital Signal Processor (DSP), microprocessor, Central Processing Unit (CPU), Microcontroller Unit (MCU), Micro Processing Unit (MPU), Neural Processing Unit (NPU), controller, Application Processor (AP), Timing Controller (TCON), but the term one or more processors 130 will be used here.

[0095] In an embodiment, one or more processors 230 may be implemented in a System-on-Chip (SoC) type, or a Large Scale Integration (LSI) type, or a Field Programmable Gate Array (FPGA) type. In an embodiment, one or more processors 130 may include volatile memory such as SRAM, etc.

[0096] Hereinafter, for ease of description, one or more processors 230 are referred to as processor 230.

[0097] According to one or more embodiments, based on the modular display device 200 receiving a control signal from the control device 400, the processor 130 of the source device 100 may receive a notification request signal corresponding to the control signal through the communication interface 120. In an embodiment, when a control signal is received from the control device 400 that interacts with the modular display device 200 connected to the source device 100, a notification request signal may be generated.

[0098] Here, the control device 400 can be a device configured to send control commands to the modular display device 200 by communicating with the modular display device 200. For example, the control device 400 can be implemented with a remote controller that interacts with the modular display device 200. At this time, the control device 400 can send control commands to the modular display device 200 by using the IR communication method. That is to say, the control device 400 can be an IR communication-based remote controller. For this purpose, the modular display devices 200 can each include an IR communication module.

[0099] Alternatively, the control device 400 can send control commands to the modular display device 200 by using the Bluetooth communication method. That is to say, the control device 400 can be a Bluetooth communication method-based remote controller. At this time, the control device 400 can be a device pre-registered in the modular display device 200 through a pairing process. For this purpose, the modular display devices 200 can each include a Bluetooth communication module.

[0100] In an embodiment, the control device 400 can be connected to the modular display device 200 by using various communication methods and can send control commands to the modular display device 200.

[0101] The embodiment is not limited thereto, and the control device 400 can be implemented with various types of electronic devices (such as smart phones, personal digital assistants (PDAs), tablet PCs, etc.) capable of sending and receiving information by communicating with the modular display device 200.

[0102] The control device 400 can be connected to the communication interface of the modular display device 200 and can send control commands to the modular display device 200. Specifically, the control device 400 can send a control signal to the modular display device 200 to request the generation of a notification request signal for the source device 100. In an embodiment, the control device 400 can send various control commands, such as adjusting the brightness, volume, etc. of the modular display device 200.

[0103] Based on the control signal for generating the notification request signal from the control device 400, after generating the notification request signal, the modular display device 200 can send the generated notification request signal to the source device 100 connected to the modular display device 200 through the communication interface of the modular display device 200.

[0104] The processor 130 of the source device 100 that receives the notification request signal through the communication interface 120 outputs notification information through the output interface 110. Therefore, the user can accurately identify the source device 100 connected to the modular display device 200 that has received a control command from the control device 400 in a space where multiple source devices 100 are arranged.

[0105] Figure 7 FIG. is a diagram showing a source device 100 that has received a notification request signal from among a plurality of source devices according to one or more embodiments of the present disclosure causing an LED module to emit light to output notification information from a modular display device 200.

[0106] In Figure 7 , when the first modular display device 200-1 disposed in the first space 1 among the plurality of modular display devices 200 included in the display system 1000 receives a control command for requesting generation of a notification request signal from the control device 400 (a remote controller based on IR communication), the first modular display device 200-1 may generate a notification request signal to be sent to the source device 100 connected to the first modular display device 200-1. In an embodiment, the first modular display device 200-1 may send the generated notification request signal to the source device 100 connected to the first modular display device 200-1.

[0107] The source device 100 that has received the notification request signal from the first modular display device 200-1 may output notification information through the output interface 110. For example, the output interface 110 may include an LED element. At this time, the processor 130 may output notification information by causing the LED element to emit light.

[0108] In an embodiment, referring back to Figure 7 , the respective output interfaces 110-1, 110-2, 110-3 of each of the plurality of source devices (the first source device 100-1, the second source device 100-2, and the third source device 100-3) disposed in the fourth space 4 may include LED elements 111-1, 111-2, and 111-3, respectively. Here, among the plurality of source devices (the first source device 100-1, the second source device 100-2, and the third source device 100-3), the source device (i.e., the second source device 100-2) that is connected to the first modular display device 200-1 and has received the notification request signal from the first modular display device 200-1 may emit notification information by causing the LED element 111-2 to emit light.

[0109] In an embodiment, the processor 130-2 of the second source device 100-2 transmits a drive current to the LED element 111-2 to control the LED element 111-2 to output light. Accordingly, a user in the fourth space 4 can intuitively identify that the source device connected to the first modular display device 200-1 (which is the modular display device 200 to be controlled by the user) is the second source device 100-2.

[0110] Accordingly, the user can perform control such that control commands for adjusting the brightness, volume, etc. of the first modular display device 200-1 are sent to the first modular display device 200-1 through the second source device 100-2, or the image data can be sent to the first modular display device 200-1 more accurately by checking the connection between the optical cable 300-2 and the second source device 100-2.

[0111] According to one or more embodiments of the present disclosure, the output interface 110 may include a speaker. At this time, the processor 130 may output sound through the speaker and output a notification message. That is, the source device 100 among the plurality of source devices 100 that has received a notification request signal from the modular display device 200 may output a sound indicating that the notification information signal has been received through the speaker. Accordingly, the user can accurately identify the source device 100 among the plurality of source devices 100 that is connected to the modular display device 200 to be controlled by the user.

[0112] Figure 8 FIG. is a diagram showing a first modular display device 200-1 for receiving a control command from a control device in a source device 100 confirmation mode according to one or more embodiments of the present disclosure.

[0113] In an embodiment, each of the modular display devices 200 may receive, from the control device 400, a signal for requesting generation of a notification information signal for the source device 100 in the source device 100 confirmation mode.

[0114] In an embodiment, the control device 400 connected to the modular display device 200 may send various control commands to the modular display device 200. In this case, when the modular display device 200 receives a control command for switching to a mode for identifying the source device 100 connected to the modular display device 200 (i.e., the source device 100 confirmation mode) from the control device 400, the modular display device 200 may switch the mode of the modular display device 200 from the normal mode to the source device 100 confirmation mode.

[0115] Here, the general mode may be a mode for receiving control commands for controlling the brightness, volume, etc. of the modular display device 200 from the control device 400, and the source device 100 confirmation mode may be a mode for receiving a control command for requesting generation of a notification information signal from the control device 400.

[0116] Therefore, in Figure 8In this case, when the first modular display device 200-1 receives a control command for switching to the source device 100 confirmation mode from the control device 400, the first modular display device 200-1 can switch the mode of the first modular display device 200-1 to the source device 100 confirmation mode and output a message that requests the transmission of a control command for requesting the generation of a notification information signal. Accordingly, the first modular display device 200-1 enables a user to recognize that the mode of the first modular display device 200-1 has been switched to the source device 100 confirmation mode.

[0117] At this time, a control command for requesting the generation of a notification information signal according to one or more embodiments of the present disclosure may be transmitted when a preset button among a plurality of buttons provided in the remote controller is pressed.

[0118] Figure 9 is a diagram of a display system 2000 according to one or more embodiments of the present disclosure.

[0119] According to one or more embodiments of the present disclosure, a plurality of source devices 100 in the display system 2000 may be connected to the first modular display device 200-1. In an embodiment, as Figure 9 shown, four source devices (a first source device 100-1, a second source device 100-2, a third source device 100-3, and a fourth source device 100-4) may be connected to one modular display device 200.

[0120] At this time, the first modular display device 200-1 may display an image through a plurality of cabinets 210-1, 210-2, 210-3, and 210-4 based on a plurality of image data provided by the plurality of source devices 100. In an embodiment, the modular display device 200 may receive image data displayed in an area corresponding to each source device (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4) from each source device (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4).

[0121] Here, the area corresponding to each source device (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4) may be an area that is separated and provided on the modular display device 200 so as not to overlap. At this time, the area corresponding to each source device (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4) may include one or more cabinets.

[0122] Return to reference Figure 9, the first modular display device 200-1 can be divided into four regions. In an embodiment, the regions can be divided into a first region, a second region, a third region, and a fourth region. The first region includes the cabinet disposed in the first row and the first column (i.e., the cabinet 210-1 disposed in the upper left corner), the second region includes the cabinet disposed in the first row and the second column (i.e., the cabinet 210-2 disposed in the upper right corner), the third region includes the cabinet disposed in the second row and the first column (i.e., the cabinet 210-3 disposed in the lower left corner), and the fourth region includes the cabinet disposed in the second row and the second column (i.e., the cabinet 210-4 disposed in the lower right corner). That is, each region (the first region to the fourth region) can include one cabinet.

[0123] At this time, the first modular display device 200-1 can receive image data related to the image displayed on the upper left cabinet 210-1 from the first source device 100-1 among the plurality of source devices 100, receive image data related to the image displayed on the upper right cabinet 210-2 from the second source device 100-2 among the plurality of source devices 100, receive image data related to the image displayed on the lower left cabinet 210-3 from the third source device 100-3 among the plurality of source devices 100, and receive image data related to the image displayed on the lower right cabinet 210-4 from the fourth source device 100-4 among the plurality of source devices 100. Similarly, the plurality of cabinets 210-1, 210-2, 210-3, and 210-4 included in the modular display device 200 can receive image data from different source devices according to the regions where the plurality of cabinets 210-1, 210-2, 210-3, and 210-4 are located.

[0124] At this time, the processor 130 of the source device 100 can output, through the output interface 110, information related to the position of the region where the image generated based on the image data transmitted by the source device 100 is displayed among the plurality of cabinets 210-1, 210-2, 210-3, and 210-4.

[0125] In an embodiment, when the plurality of source devices 100 are connected to the first modular display device 200-1, each source device 100 can output, through the output interface 110, information indicating the position of the region where the image generated based on the image data transmitted by each source device 100 is displayed. That is, each source device 100 can display the position of the region set for each source device 100 among the plurality of regions of the first modular display device 200-1 for distinction.

[0126] For example, return reference Figure 9, the first source device 100-1 can output, through the output interface 110, information indicating the position of the area where the image generated based on the image data transmitted by the first source device 100-1 is displayed (i.e., the position of the upper left area in the first modular display device 200-1). In one embodiment, the second source device 100-2 can output, through the output interface 110, information indicating the position of the area where the image generated based on the image data transmitted by the second source device 100-2 is displayed (i.e., the position of the upper right area in the first modular display device 200-1). In one embodiment, the third source device 100-3 can output, through the output interface 110, information indicating the position of the area where the image generated based on the image data transmitted by the third source device 100-3 is displayed (i.e., the position of the lower left area in the first modular display device 200-1). In an embodiment, the fourth source device 100-4 can output, through the output interface 110, information indicating the position of the area where the image generated based on the image data transmitted by the fourth source device 100-4 is displayed (i.e., the position of the lower right area in the first modular display device 200-1).

[0127] For example, the processor 130 of the source device 100 can output the position information through a plurality of LED elements 111 included in the output interface 110. At this time, the plurality of LED elements 111 can be arranged according to the layout format of the plurality of cabinets. In an embodiment, the processor 130 can output information related to the position of the area by causing the LED elements corresponding to the cabinets among the plurality of LED elements 111 to emit light.

[0128] In an embodiment, each of the plurality of source devices 100 can include a plurality of LED elements 111, the number of the plurality of LED elements 111 corresponding to the number of the plurality of areas of the first modular display device 200-1 to which the plurality of source devices 100 are connected together (specifically, the plurality of areas respectively corresponding to the plurality of source devices 100), and the plurality of LED elements 111 can be arranged on one side of each source device 100 according to the arrangement of the plurality of source areas.

[0129] Figure 10 The figure shows outputting position information by causing the LED elements arranged at positions corresponding to the positions of the areas corresponding to the source device 100 among the plurality of LED elements according to one or more embodiments of the present disclosure.

[0130] For example, in Figure 10In [the situation], when four source devices 100 are connected to the first modular display device 200-1, and each source device 100 is set to correspond to four regions (each region including one cabinet) in the first modular display device 200-1, in each of the four source devices 100, four LED elements 111-1, 111-2, 111-3, and 111-4 arranged according to the layout format of the four regions (i.e., the 2×2 matrix format) can be disposed on one side of each source device 100. That is to say, four LED elements 111-1, 111-2, 111-3, and 111-4 arranged in a 2×2 format can be disposed on one side of each source device 100.

[0131] At this time, the processor 130 of each source device 100 can send a control signal to the driver in the source device 100, so as to supply a drive current to the LED element indicating the position of the region corresponding to each source device 100. Therefore, each source device 100 can cause the LED elements disposed at the positions corresponding to the positions of the following regions in the modular display device to emit light: an image generated based on the image data sent by the corresponding source device 100 is displayed in this region.

[0132] That is to say, in Figure 10 since the LED element 111-1 disposed at the upper left end among the four LED elements 111-1, 111-2, 111-3, and 111-4 of the first source device 100-1 emits light, the user can intuitively recognize that the first source device 100-1 sends the image data for the image to be displayed in the upper left region of the first modular display device 200-1. Similarly, the user can intuitively recognize in which region of the first modular display device 200-1 the regions corresponding to the second source device 100-2 to the fourth source device 100-4 are located.

[0133] According to one or more embodiments of the present disclosure, the output interface 110 of the source device 100 may include a display panel. At this time, the processor 130 can control the display panel to display a plurality of graphic objects arranged according to the layout format of the plurality of cabinets 210. In an embodiment, the processor 130 can display the graphic object corresponding to the region corresponding to the source device 100 among the plurality of graphic objects in a first color, and display the remaining graphic objects in a second color, so as to output the information about the position of this region.

[0134] Figure 11 is a diagram showing the output of the position information of the region corresponding to the source device 100 through a plurality of graphic objects according to one or more embodiments of the present disclosure.

[0135] In an embodiment, each of the plurality of source devices 100 may further include a display panel. Through the display panel, each source device 100 may display position information of an area corresponding to each source device 100. At this time, the display panel may be implemented using a liquid crystal (LCD) panel, a light emitting diode (LED) panel, a plasma display panel (PDP), an organic light emitting diode (OLED) panel, etc., according to the display method. At this time, the source device 100 may further include additional configurations according to the implementation type of the display panel. For example, if the display is made of liquid crystal, the display may include an LCD display panel, a backlight unit that provides light, and a panel driving substrate that drives the panel.

[0136] In an embodiment, each source device 100 may display a plurality of graphic objects arranged according to the layout format of a plurality of areas through the display panel. In Figure 11 If four source devices (a first source device 100-1, a second source device 100-2, a third source device 100-3, and a fourth source device 100-4) are connected to a first modular display device 200-1, and each source device (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4) is set to correspond to four areas (four areas each including one cabinet) in the first modular display device 200-1, then the four source devices (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4) may each display four graphic objects 31, 32, 33, and 34 arranged according to the layout format of the four areas (i.e., a 2×2 matrix format) through the display panel.

[0137] At this time, each source device 100 may display the position information of the area corresponding to the source device 100 by displaying the color of the graphic object arranged at a position corresponding to the area corresponding to each source device 100 among the plurality of graphic objects 31 to 34 as different from the colors of the remaining graphic objects.

[0138] That is, in Figure 11 , the processor 130 of the first source device 100-1 may make the user intuitively recognize that the first source device 100-1 transmits image data related to the image displayed in the upper left area of the first modular display device 200-1 by displaying the color of the graphic object 31 set in the upper left among the four graphic objects 31 to 34 as a bright color different from the other graphic objects.

[0139] Similarly, the processor 130 of each of the second to fourth source devices 100-4 may display the position information of the area corresponding to each source device 100 by displaying the color of the graphic object set at a position corresponding to the position of the area where the image is displayed based on the image data transmitted by each source device 100 to be different from the colors of the remaining graphic objects.

[0140] Figure 12 is a diagram of a display system according to one or more embodiments of the present disclosure.

[0141] Figure 13a and Figure 13b is a diagram showing that among multiple source devices according to one or more embodiments of the present disclosure, the source device 100 that has received a notification request signal from the modular display device 200 causes the LED module to emit light to output notification information.

[0142] According to one or more embodiments of the present disclosure, any one of the multiple modular display devices 200 in the display system 1000 may be connected to multiple source devices 100, and the remaining modular display devices may be connected to one source device 100. That is, the number and connection status of the multiple modular display devices 200 connected to the source device may be different from each other.

[0143] In one embodiment, as Figure 12 shown, four source devices (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4) may be connected to the first modular display device 200-1 among the multiple modular display devices 200. In the embodiment, the second modular display device 200-2 may be connected to one source device 100-5. Figure 12 The modular display device 200-1 shown may correspond to Figure 10 the modular display device shown.

[0144] At this time, according to one or more embodiments of the present disclosure, the processor 130 may output, through the output interface 110, information indicating the position of the area where the image generated based on the image data transmitted by the source device 100 is displayed on the modular display device 200 when the source device 100 and one or more other source devices are connected to the common modular display device 200, and may output notification information through the output interface 110 when receiving a notification request signal from the modular display device 200 through the communication interface 120.

[0145] In an embodiment, the processor 130 may identify the connection state between the source device 100 and the modular display device 200. In an embodiment, the processor 130 may identify whether the source device 100 and another source device other than the source device 100 are commonly connected to the modular display device 200. In an embodiment, when the processor 130 identifies that the source device 100 and another source device other than the source device 100 are commonly connected to the modular display device 200, the processor 130 may output, through the output interface 110, information indicating the position of the area on the modular display device 200 where an image generated based on the image data transmitted by the source device 100 is displayed in real time.

[0146] In contrast to the foregoing, if it is not identified that a source device other than the source device 100 is commonly connected to the modular display device 200 (i.e., when it is identified that the source device is connected to one modular display device 200), the processor 130 may not output information indicating the position of the area on the modular display device 200 where an image generated based on the image data transmitted by the source device 100 is displayed.

[0147] When the processor 130 of the source device 100 simultaneously receives a notification request signal from the modular display device 200 connected to the source device 100 through the communication interface 120, the processor 130 of the source device 100 may output notification information through the output interface 110.

[0148] Therefore, the output interface 110 of the source device 100 may include an output interface (first output interface) for outputting information indicating the position of the area where an image is displayed when the source device 100 and another source device are commonly connected to the modular display device 200 and an output interface (second output interface) for outputting notification information.

[0149] In an embodiment, in Figure 12 when the source device 100 and another source device are commonly connected to the modular display device 200, the first LED element 111 to the fourth LED element 114 are used to output information indicating the position of the area where an image is displayed, and when a notification request signal is received from the modular display device 200, the fifth LED element 115 is used to output notification information through the output interface 110.

[0150] In Figure 12Among them, the four source devices (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4) connected to the first modular display device 200-1 can output information in real time through the output interface 110, and this information indicates the position of the area where the image generated based on the image data sent by each source device 100 is displayed. In an embodiment, the processor 130 of each source device 100 may send a control signal to the driver in the source device 100, so that drive current is provided to the LED elements 111 to 114 indicating the position of the area corresponding to each source device 100. Therefore, each source device 100 can cause the LED elements arranged at positions corresponding to the positions of the following areas in the modular display device 200 to emit light: on this area, an image generated based on the image data sent by the corresponding source device 100 is displayed.

[0151] In an embodiment, when a source device 100-5 is connected to the second modular display device 200-2, the first LED element 111 to the fourth LED element 114 for outputting information indicating the position of the area where the image is displayed do not emit light, thereby indicating that the source device 100-5 is connected to a modular display device (that is, the second modular display device 200-2).

[0152] In Figure 13a Among them, when the first modular display device 200-1 arranged in the seventh space 7 among the multiple modular display devices 200 included in the display system 1000 receives a control command for requesting to generate a notification request signal from the control device 400 (a remote controller based on IR communication), the first modular display device 200-1 can generate a notification request signal to be sent to the multiple source devices (the first source device 100-1, the second source device 100-2, the third source device 100-3, and the fourth source device 100-4) connected to the first modular display device 200-1.
