Description

Display device and control method thereof

[0001] The present disclosure relates to a display device and a control method thereof, and more particularly, to a display device for dehumidifying a replaced display among a plurality of displays included in the display device and a control method thereof.

[0002] Recently, the use of modular display devices that provide a display screen by combining multiple LED display modules has been increasing.

[0003] During use, these modular display devices may experience module failures, necessitating replacement. In such cases, when replacing a module that was previously stored, dehumidification of the replaced module may be necessary, depending on the conditions of the storage location.

[0004] To achieve this, there was a problem that the dehumidification mode through the TCON board of the modular display device had to be manually executed using a JIG and S / W program, etc. In addition, if the dehumidification mode is not executed manually after the module is replaced and the screen is accidentally turned on immediately due to an operator or user error, the screen may become overexposed. In this case, the modular display device may operate in normal mode without the moisture in the module being removed, which may result in module failure.

[0005] Accordingly, there is a growing need for a technology that can automatically identify whether a module constituting a modular display device needs to be replaced and automatically execute a dehumidification mode.

[0006] According to one embodiment of the present disclosure, a display device includes a plurality of displays, a memory storing at least one instruction, and at least one processor executing the at least one instruction, wherein the at least one processor, when the display device is activated, identifies whether at least one display that is a replacement display that has been replaced before the display device is activated exists among the plurality of displays based on initial setting data and module data corresponding to each of the plurality of displays, and when it is identified that at least one display that is a replacement display exists, acquires a dehumidification mode for dehumidifying each display among the at least one display that is a replacement display based on the module data corresponding to each display among the at least one display that is a replacement display, and controls each display among the at least one display that is a replacement display to operate in the acquired dehumidification mode for the display.

However, this is not intended to limit the scope to specific embodiments, but should be understood to encompass various modifications, equivalents, and / or alternatives of the embodiments of the present disclosure. In connection with the description of the drawings, similar reference numerals may be used for similar components.

[0038] In describing the present disclosure, if it is determined that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present disclosure, a detailed description thereof will be omitted.

[0039] Additionally, the following embodiments may be modified in various other forms, and the scope of the technical concepts of the present disclosure is not limited to the following embodiments. Rather, these embodiments are provided to further faithfully and completely convey the technical concepts of the present disclosure to those skilled in the art.

[0040] The terminology used in this disclosure is for the purpose of describing specific embodiments only and is not intended to limit the scope of the rights. Singular expressions include plural expressions unless the context clearly dictates otherwise.

[0041] In this disclosure, expressions such as “has,” “can have,” “includes,” or “may include” indicate the presence of a corresponding feature (e.g., a component such as a number, function, operation, or part), and do not exclude the presence of additional features.

[0042] In this disclosure, expressions such as “A or B,” “at least one of A and / or B,” or “one or more of A or / and B” can include all possible combinations of the listed items. For example, “A or B,” “at least one of A and B,” or “at least one of A or B” can all refer to (1) including at least one A, (2) including at least one B, or (3) including both at least one A and at least one B.

[0043] The expressions “first,” “second,” “first,” or “second,” etc., used in this disclosure can describe various components, regardless of order and / or importance, and are only used to distinguish one component from another, but do not limit the components.

[0044] When it is said that a component (e.g., a first component) is “(operatively or communicatively) coupled with / to” or “connected to” another component (e.g., a second component), it should be understood that said component may be directly coupled to said other component, or may be coupled via another component (e.g., a third component).

[0045] On the other hand, when it is said that a component (e.g., a first component) is "directly connected" or "directly connected" to another component (e.g., a second component), it can be understood that no other component (e.g., a third component) exists between said component and said other component.

[0046] The expression "configured to" as used in the present disclosure may be used interchangeably with, for example, "suitable for," "having the capacity to," "designed to," "adapted to," "made to," or "capable of." The term "configured to" may not necessarily mean only "specifically designed to" in terms of hardware.

[0047] Instead, in some contexts, the phrase "a device configured to" may mean that the device, in conjunction with other devices or components, is "capable of" performing A, B, and C. For example, the phrase "a processor configured (or set) to perform A, B, and C" may refer to a dedicated processor (e.g., an embedded processor) for performing those operations, or a general-purpose processor (e.g., a CPU or application processor) that can perform those operations by executing one or more software programs stored in a memory device.

[0048] In the embodiments, a 'module' or 'part' performs at least one function or operation, and may be implemented as hardware or software, or as a combination of hardware and software. Furthermore, a plurality of 'modules' or 'parts' may be integrated into at least one module and implemented as at least one processor, except for a 'module' or 'part' that needs to be implemented as a specific hardware.

[0049] Meanwhile, the various elements and areas in the drawings are schematically drawn. Therefore, the technical concept of the present invention is not limited by the relative sizes or spacing depicted in the attached drawings.

[0050] Hereinafter, with reference to the attached drawings, embodiments according to the present disclosure will be described in detail so that a person having ordinary knowledge in the technical field to which the present disclosure pertains can easily implement the present disclosure.

[0051] FIG. 1 is a drawing for explaining a display device according to one or more embodiments of the present disclosure.

[0052] According to FIG. 1, a display device (100) and a display device (100') before display replacement are illustrated. The display device (100) may include a plurality of displays (111 to 119).

[0053] Here, at least one of the plurality of displays (111 to 119) can be replaced with another module. The display device (100) may correspond to a display device (100) in which one display (115') among the plurality of displays (111, 112, 113, 114, 115', 116, 117, 118, 119) included in the display device (100') before replacement is replaced with another display (115). In the present disclosure, the display device (100) may be referred to as a 'display device after replacement', a 'display device after module replacement', or a 'display device after display replacement'.

[0054] Here, the display device (100) or the display device (100') before display replacement can output an image received from an external device or content previously stored in each display device (100, 100'). Here, the external device, a separate content source, may correspond to a device that provides content to each display device (100, 100'). In addition, the external device can be connected to each display device (100, 100') via an optical cable, an HDMI cable, or the like. The content source can be implemented as the above-described set-top box, smartphone, TV, PC, media box, etc., but is not limited thereto.

[0055] Each display device (100, 100') includes a plurality of display modules, and each of the plurality of display modules may include a plurality of LED elements. Here, the plurality of display modules may be expressed as 'a plurality of displays' or 'a plurality of modules'. Specifically, each display (111 to 119, 115') may be implemented in various forms such as an LCD (liquid crystal display), an OLED (organic light-emitting diode), an LCoS (Liquid Crystal on Silicon), a DLP (Digital Light Processing), a QD (quantum dot) display panel, a QLED (quantum dot light-emitting diodes), a μLED (Micro light-emitting diodes), a Mini LED, etc.

[0056] Meanwhile, each of the plurality of displays (111 to 119, 115') may be implemented as a touch screen combined with a touch sensor, a flexible display, a rollable display, a 3D display, a display in which a plurality of display modules are physically connected, etc.

[0057] Meanwhile, each display device (100, 100') may be referred to by various expressions representing the same or similar concepts. For example, the display device may be referred to by the expression "display cabinet." Here, multiple cabinets may be assembled to form a single modular display device, and each cabinet may include multiple LED modules. In this case, each of the above-described multiple displays (111 to 119, 115') may be implemented as an LED module.

[0058] Here, the modular display device can be implemented as a TV, but is not limited thereto, and can be applied to any device with display functions, such as a video wall, a large format display (LFD), a digital signage, a digital information display (DID), a projector display, etc., without limitation. Alternatively, the display device (100, 100') can be implemented not only as the various independent devices described above, but can also be implemented in the form of a display panel or module applicable to such devices. A case in which it is implemented as a display panel applicable to such devices will be described in detail in the following section.

[0059] In FIG. 1, a case is illustrated where the display device (100, 100') is implemented as a 3X3 sized display device (100, 100') with three displays arranged in a horizontal direction and three displays arranged in a vertical direction. However, the number, arrangement direction, arrangement location, shape, etc. of the display devices (100, 100') may be variously modified depending on the purpose of use, location, etc. of the display devices (100, 100'). Here, a plurality of displays (111 to 119, 115') may be physically and electrically connected through terminals, etc., provided on each display (111 to 119, 115').

[0060] In this case, one of the multiple LED modules included in the display device (100') prior to replacement may be replaced with a new LED module. In this case, the display device (100) may also be implemented as a cabinet including the new LED module.

[0061] However, it is not limited to each display device (100, 100') being implemented as a cabinet as in the above-described example, and each display device (100, 100') may be implemented as a display device (100, 100') including a plurality of cabinets. In this case, each of the plurality of displays (111 to 119, 115') described above may be implemented as a cabinet including a plurality of LED modules. For example, one (115') of the plurality of cabinets included in the display device (100') before replacement may be replaced with a new cabinet. At this time, the display device (100) may be implemented as a display device (100) including a new cabinet.

[0062] However, the present invention is not limited thereto, and even when each display device (100, 100') includes multiple cabinets, the multiple displays (111 to 119, 115') may be implemented with multiple LED modules. For example, one of the multiple LED modules (115') included in the cabinet of the display device (100') prior to replacement may be replaced. In this case, the display device (100) may be implemented as a display device (100) including a new LED module.

[0063] In the present disclosure, for convenience of explanation, it is assumed that each display device (100, 100') is implemented as a cabinet including a plurality of LED modules, as in the example described above, and that one of the plurality of LED modules included in the cabinet is replaced before replacement.

[0064] According to one or more embodiments, the display device (100) can identify whether at least one replaced display (115) exists before the display device (100) is activated. If it is identified that a replaced display (115) exists, a dehumidification mode can be executed based on module data corresponding to the replaced display to control the replaced display (115) to be dehumidified. The detailed configuration of the display device (100) that performs such an operation will be described in detail below.

[0065] FIG. 2 is a block diagram illustrating a configuration of a display device according to one or more embodiments of the present disclosure.

[0066] According to FIG. 2, the display device (100) may include a plurality of displays (110), a memory (120), and at least one processor (130). Although FIG. 2 illustrates that the display device (100) includes only basic components (i.e., a display, a memory, a processor), the display device (100) may further include various components in addition to the above-described components.

[0067] A plurality of displays (110) are configured to display various screens under the control of at least one processor (130) of the display device (100). The plurality of displays (110) may correspond to the plurality of displays (111 to 119) illustrated in FIG. 1. Since each of the plurality of displays (110) has been described in FIG. 1, a redundant description thereof will be omitted.

[0068] The memory (120) may be implemented in the form of memory embedded in the display device (100) or may be implemented in the form of memory that can be attached or detached from the display device (100) depending on the purpose of data storage. For example, data for driving the display device (100) may be stored in a memory embedded in the display device (100), and data for the expansion function of the display device (100) may be stored in a memory that can be attached or detached from the display device (100). When implemented as a memory embedded in the display device (100), the memory (120) may be at least one of volatile memory (e.g., dynamic RAM (DRAM), static RAM (SRAM), or synchronous dynamic RAM (SDRAM)), non-volatile memory (e.g., one time programmable ROM (OTPROM), programmable ROM (PROM), erasable and programmable ROM (EPROM), electrically erasable and programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (e.g., NAND flash or NOR flash), hard drive, or solid state drive (SSD)).

[0069] Meanwhile, in the illustrated example, the display device (100) is depicted as being composed of one memory, but when referring to volatile memory and non-volatile memory separately, the display device (100) may be referred to as including multiple memories.

[0070] The memory (120) according to one or more embodiments may store at least one instruction. Here, the at least one instruction may correspond to at least one command for the display device (100) to identify whether a replaced display exists among a plurality of displays (110) included in the display device (100) and to cause the replaced display to operate in a dehumidification mode according to a dehumidification mode for dehumidifying the replaced display. The memory (120) may also store information necessary for the operation of the display device (100).

[0071] According to one or more embodiments, the memory (120) may store initial setup data and module data for each of the plurality of displays (110).

[0072] Here, the memory (120) may include a plurality of flash memories, and each flash memory may be provided to each of the plurality of displays (110). The above-described module data may be stored in the flash memories provided to each of the plurality of displays (110). Here, the flash memory corresponds to a type of non-volatile storage device, and may correspond to a storage device that can read and write data relatively quickly compared to other storage devices. Here, non-volatile memory may refer to a memory in which stored data is not erased even when the power is turned off.

[0073] For example, flash memory may be provided in each of a plurality of displays (110) to store module data of each display (110), such as calibration information, manufacturing date information, and other various display setting values.

[0074] According to one or more embodiments, at least one processor (130) may identify at least one replaced display among the plurality of displays (110) using initialization data and module data stored in the memory (or flash memory) (120). For example, at least one processor (130) may identify the replaced display using calibration data recorded in binary format included in each of the initialization data and the module data. This will be described in detail with reference to FIG. 3.

[0075] At least one processor (130) can perform overall control operations of the display device (100). Specifically, at least one processor (130) has a function of controlling overall operations of the display device (100).

[0076] At least one processor (130) may be implemented as a digital signal processor (DSP), a microprocessor, or a time controller (TCON) that processes a digital signal. However, the present invention is not limited thereto, and may include one or more of a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a graphics-processing unit (GPU), a communication processor (CP), or an ARM processor, or may be defined by the relevant term. In addition, at least one processor (130) may be implemented as a system on chip (SoC) or large scale integration (LSI) having a built-in processing algorithm, or may be implemented in the form of a field programmable gate array (FPGA). In addition, at least one processor (130) may perform various functions by executing computer executable instructions stored in a memory. This will be described in detail in FIG. 8. Meanwhile, FIG. 2 shows a display. Although the device (100) is shown as including only one processor, it may include multiple processors (e.g., CPU + GPU, CPU + DSP) when implemented.

[0077] According to one or more embodiments, at least one processor (130) may be connected to a plurality of displays (110) and memories (120) to control the display device (100).

[0078] According to one or more embodiments, when the display device (100) is activated, it is possible to identify whether there is at least one display among the plurality of displays (110) that was replaced before the display device was activated, based on initial setup data stored in the memory (120) and module data preset for each of the plurality of displays (110).

[0079] Here, the activation of the display device (100) may mean that power is supplied to the display device (100) and it turns on (or boots up), or that it switches from standby mode to normal mode. In this case, the standby mode may mean a mode other than the normal mode in which the display device (100) can normally output an image. For example, the standby mode may correspond to a mode corresponding to a standby state for replacing at least one display among a plurality of displays (110). However, the activation of the display device (100) is not limited to the above-described examples, and may mean an operation in which the display device (100) switches to a state in which it can normally output an image.

[0080] Meanwhile, at least one of the plurality of displays (110) included in the display device (100) may correspond to a display that has been replaced before the display device (100) is activated. In this case, the display device (100) can identify whether the replaced display exists among the plurality of displays (110). The display device (100) can identify whether the replaced display exists based on initial setting data stored in the memory (or flash memory included in the memory) and preset module data for each of the plurality of displays (110). For example, the preset module data may correspond to data set through an initial setting process (e.g., a calibration process) during the manufacturing stage or initial use stage of the display device (100).

[0081] For example, at least one processor (130) may compare initial setting data with module data corresponding to each of the plurality of displays (110), and if module data corresponding to at least one display among the module data corresponding to each of the plurality of displays (110) is identified as different from the initial setting data, at least one display may be identified as at least one replaced display, and at least one replaced display may be identified as existing. Here, the operation of at least one processor (130) comparing the initial setting data and module data will be described in detail later in FIG. 3.

[0082] Here, the initial setup data and module data corresponding to each of the plurality of displays (110) may include calibration data for correcting at least one parameter corresponding to each of the plurality of displays (110). At least one processor (130) may compare the first calibration data included in the initial setup data with the second calibration data corresponding to each of the plurality of displays (110), and if the second calibration data corresponding to at least one display among the second calibration data corresponding to each of the plurality of displays (110) is identified as being different from the first calibration data, the at least one display may be identified as at least one replaced display. This will be described in detail later with reference to FIG. 3.

[0083] For example, each of the first calibration data and the second calibration data may include a plurality of bits, the first calibration data may include at least one first bit set to identify whether a display is replaced, and the second calibration data may include at least one second bit located at the same bit position as the at least one first bit. At this time, at least one processor (130) may compare the at least one first bit and the at least one second bit, and if the at least one first bit and the at least one second bit are identified as different, at least one display corresponding to the at least one second bit may be identified as at least one replaced display. This will be described in detail later with reference to FIG. 4.

[0084] Meanwhile, at least one processor (130) may update at least one second bit corresponding to at least one display for which the dehumidification operation has been completed to be identical to at least one first bit when the dehumidification operation corresponding to the dehumidification mode is completed. This will be described in detail later in FIG. 5.

[0085] According to one or more embodiments, when at least one replaced display is identified as present, at least one processor (130) may acquire a dehumidification mode for dehumidifying the at least one replaced display based on module data corresponding to the at least one replaced display.

[0086] Here, the module data corresponding to the replaced display may correspond to module data stored in the flash memory of the display identified as replaced. Specifically, at least one processor (130) may identify at least one display having module data different from the initial setting data, and then acquire a dehumidification mode based on the module data corresponding to the corresponding display.

[0087] Here, dehumidification may refer to an operation to remove moisture from a replaced display. In this case, operating in dehumidification mode may refer to an operation to drive the replaced display to an appropriate degree to prevent or remove moisture infiltration. For example, operating in dehumidification mode may refer to performing an operation to apply an electric signal (in the form of current or voltage) of a certain size to at least one replaced display or an LED included in the display. A display operating in dehumidification mode may maintain a black screen or display a screen of another single color (e.g., a blue screen). Here, maintaining a black screen may refer to at least one processor (130) blocking an image signal for displays other than the replaced display and may refer to cutting off power supplied to the remaining displays. However, the present invention is not limited thereto, and the display device (100) may display an image indicating a dehumidification status.

[0088] For example, if at least one processor (130) identifies that at least one replaced display exists, it may acquire a dehumidification mode for dehumidifying at least one replaced display based on manufacturing date data included in module data corresponding to at least one replaced display. This will be described in detail later in FIG. 6.

[0089] At this time, at least one processor (130) can identify the storage period based on the current date and manufacturing date data stored in the memory (120), and acquire a mode corresponding to the storage period as a dehumidification mode.

[0090] Here, the dehumidification mode may be one of multiple dehumidification modes distinguished based on at least one predetermined period. At least one processor (130) may compare the storage period with at least one predetermined period to determine the dehumidification mode. This will be described in detail later in FIG. 7.

[0091] According to one or more embodiments, at least one replaced display may be controlled to operate in a dehumidifying mode. Operating in the dehumidifying mode may mean that at least one processor applies an electrical signal of a certain magnitude (e.g., current or voltage) to the replaced display or LED.

[0092] At this time, if at least one processor (130) identifies that at least one replaced display exists, it may deactivate at least one display among the plurality of displays (110) except for at least one replaced display while operating in the dehumidifying mode. This will be described in detail later in FIG. 9.

[0093] For example, at least one processor (130) may control at least one display, excluding at least one replaced display, among the plurality of displays (110) to display a screen including dehumidification mode progress information. This will be described in detail later in FIG. 10.

[0094] FIG. 3 is a diagram illustrating module data according to one or more embodiments of the present disclosure.

[0095] According to FIG. 3, first to ninth displays (111 to 119) are illustrated. At least one processor (130) can compare second calibration data (2nd Cal data) of each of the first to ninth displays (111 to 119) with first calibration data (1st Cal data).

[0096] Here, the first calibration data and the second calibration data may correspond to data included in the initial setup data and module data, respectively. The first calibration data and the second calibration data may include values ​​that may change depending on the initial setup, etc.

[0097] According to one or more embodiments, when the display device (100) is activated, at least one processor (130) may compare initial setup data with module data corresponding to each of the plurality of displays (111 to 119). Then, at least one processor (130) may identify that module data corresponding to at least one display among the module data corresponding to each of the plurality of displays (111 to 119) is different from the initial setup data. Thereafter, at least one processor (130) may identify that at least one replaced display exists.

[0098] Specifically, the initial setting data may include initial setting values ​​related to the operation of the display device (100). These initial setting values ​​may be adjusted by the manufacturer or user during the manufacturing stage or initial use stage of the display device (100) and stored in the memory (120).

[0099] Meanwhile, the module data may include various information (e.g., brightness, color, contrast ratio, product number, manufacturing date information, etc.) related to each of the plurality of displays (111 to 119). The module data may include values ​​adjusted to match each of the plurality of displays (111 to 119) through initial settings. That is, the module data before the initial settings are made may be different for each of the plurality of displays (111 to 119). Here, the flash memory (Module Cal Flash) provided in each of the plurality of displays (111 to 119) may store module data of each of the plurality of displays (111 to 119).

[0100] Meanwhile, existing displays that have not been replaced among the plurality of displays (111 to 119) included in the display device (100) may include data that matches the aforementioned initial setting data. This is because, during the manufacturing stage of the display device (100), after module data is initially set for the plurality of displays that are assembled together, the initial setting data including the initially set values ​​may be stored.

[0101] On the other hand, if the plurality of displays (111 to 119) include at least one replaced display, the flash memory of the replaced display may also store module data, but the module data corresponding to the replaced display may not match the initial setup data described above.

[0102] Accordingly, at least one processor (130) can compare the initial setting data with the module data of each of the plurality of displays (111 to 119) to identify whether at least one replaced display exists among the plurality of displays (111 to 119).

[0103] According to one or more embodiments, the initial setup data and module data for each of the plurality of displays (110) may include calibration data. Here, the calibration data may correspond to data for correcting at least one parameter corresponding to each of the plurality of displays (111 to 119). That is, the calibration data may refer to a plurality of values ​​for allowing the plurality of displays (111 to 119) constituting the display device (100) to exhibit optimal performance. For example, the calibration data may correspond to data for adjusting the color, brightness, contrast ratio, etc. of the screen displayed by each of the plurality of displays (111 to 119) to maintain consistent screen quality. Here, calibration may refer to a process of adjusting the color, brightness, contrast ratio, etc.

[0104] According to one or more embodiments, at least one processor (130) may compare first calibration data included in the initial setup data with second calibration data corresponding to each of the plurality of displays. Then, if the second calibration data corresponding to at least one display among the second calibration data corresponding to each of the plurality of displays (111 to 119) is identified as different from the first calibration data, the at least one processor (130) may identify at least one display as at least one replaced display.

[0105] At this time, existing displays that have not been replaced among the plurality of displays (111 to 119) included in the display device (100) may include data that matches the first calibration data. This is because, during the manufacturing stage of the display device (100), etc., the second calibration data is corrected through a calibration process, and the corrected calibration value is stored as the first calibration value.

[0106] On the other hand, if the plurality of displays (111 to 119) include at least one replaced display, the flash memory of the replaced display may also store the second calibration data. In this case, the second calibration data corresponding to the replaced display may not match the initial setting data described above.

[0107] Accordingly, at least one processor (130) can compare the first calibration data with the second calibration data of each of the plurality of displays (111 to 119) to identify whether at least one replaced display exists among the plurality of displays (111 to 119).

[0108] If at least one processor (130) reads the second calibration data of each of the plurality of displays (111 to 119), and if there is second calibration data that does not match the first calibration data, at least one display corresponding to the second calibration data can be identified as a replaced display. Accordingly, at least one processor (130) can identify that a replaced display exists through a data comparison process.

[0109] Meanwhile, each of the above-described calibration data may correspond to data that can be recorded as numbers. This will be described in detail below.

[0110] FIGS. 4 and 5 are diagrams illustrating a plurality of bits according to one or more embodiments of the present disclosure.

[0111] According to FIG. 4, table (1) may include initial setting data (10) and second calibration data (20) corresponding to each of a plurality of displays (111 to 119), and the initial setting data (10) may include a plurality of bits including a first bit (10-1), and the second calibration data (20) may include a plurality of bits including a second bit (21-1 to 29-1). The second calibration data (20) may include second calibration data (21 to 29) corresponding to each of the plurality of displays (111 to 119). Here, the initial setting value may be included in the above-described initial setting data (10) and may also be expressed as the first calibration data (10). That is, table (1) may correspond to a table in which the first calibration data (10) and the second calibration data (20) are arranged by each bit position. Here, bit position can mean the location of each bit in a number expressed in binary.

[0112] According to one or more embodiments, each of the first calibration data (10) and the second calibration data (20) may include a plurality of bits, the first calibration data (10) may include at least one first bit (10-1) set to identify whether the display is to be replaced, and the second calibration data (20) may include at least one second bit located at the same bit position as the at least one first bit (10-1).

[0113] For example, through a calibration process at the manufacturing stage, etc., the first calibration data (10) and the second calibration data (20) can be set to be identical. In this calibration process, the manufacturer, etc. can set a specific bit position to have a specific value so that whether or not to replace the module in the future can be identified. Here, the specific bit position may correspond to the bit position of each of the first bit and the second bit described above.

[0114] Specifically, the manufacturer, etc. may set specific bits (10-1, 21-1 to 21-9) included in each of the first calibration data (10) and the second calibration data (20) to all have the same value (e.g., 1 out of 0 or 1). The example of Fig. 4 may correspond to a case where, in the manufacturing stage of the display device (100), the manufacturer, etc. sets the LSB (Least Significant Bit) of the second calibration data (20) to each have the value 1. In this case, the first bit and the second bit may correspond to the LSB in the first calibration data (10) and the second calibration data (20), respectively.

[0115] At this time, setting values ​​(e.g., brightness, color, contrast ratio, etc.) according to calibration can be input in the remaining bits except for the LSB of the second calibration data (20). Thereafter, the first calibration data (10) can be stored including the initial setting information of the second calibration data (20). Here, the initial setting information can include the corrected setting values, etc. when calibration is performed for each of the plurality of displays (111 to 119). That is, the first calibration data (10) can include information on the setting values ​​set in the manufacturing stage (or initial stage) and the initial setting bits (e.g., 1) for identifying whether the display is replaced.

[0116] Meanwhile, after the manufacturing stage of the display device (100), there may be cases where some displays need to be replaced due to aging or failure, etc., during the usage stage, etc. In this case, the user may replace some of the existing multiple displays included in the display device (100) with new displays. Here, the new display may correspond to a replacement display produced separately from the displays assembled together during the manufacturing stage of the display device (100). Here, the replacement display may be referred to as a "service module", a "service display", etc.

[0117] For example, during the manufacturing stage of a replacement display, the manufacturer or the like may also input calibration data into the flash memory of the replacement display. Here, the calibration data may correspond to the second calibration data described above. At this time, the manufacturer or the like may input a specific value (e.g., 0) into the second bit so that the display device (100) can automatically identify whether the display has been replaced when the replacement display is later used to replace the display of the display device (100). That is, when the second bit is set to 1 for the existing display of the display device (100), the second bit may be set to 0 during the manufacturing stage for the replacement display.

[0118] In this case, if initial settings (e.g., brightness, color, contrast ratio, etc.) are set for the replacement display through a calibration process in the future, the remaining multiple bits, excluding the second bit, may match the corresponding bits of the existing display. However, since the second bit of the replaced display is different from the second bit of the existing display, the display device (100) can identify whether the display has been replaced by comparing each second bit.

[0119] According to one or more embodiments, the display device (100) compares at least one first bit (10-1) and at least one second bit (21-1 to 29-1), and if at least one first bit (10-1) and at least one second bit (25-1) are identified as different, the display device (100) can identify at least one display (115) corresponding to at least one second bit (25-1) as at least one replaced display (115).

[0120] For example, when the display device (100) is activated, the display device (100) can compare the first bit (10-1) of the first calibration data (10) with the second bits (21-1 to 29-1) of the second calibration data (20). For example, when the first bit is stored as 1, the second calibration data (25) in which the second bit (25-1) is 0 can be identified. At this time, the display (115) corresponding to the second calibration data (25) in which the second bit (25-1) is 0 can be identified as a replaced display.

[0121] For example, if each display (111 to 119) is implemented as an LED module including a plurality of LED elements and the LED module is replaced, and if the display device (100) is implemented as a device including one cabinet composed of a plurality of LED modules, the display device (100) can identify a module in which the second bit is 0 after reading the second calibration data (25) from the flash memory of each LED module. In this case, the display device (100) can identify that the corresponding LED module is a replaced module and perform a dehumidifying operation on the replaced LED module.

[0122] Through this, the display device (100) can efficiently identify whether the display needs to be replaced by using the calibration data stored in each display (111 to 119).

[0123] Meanwhile, in the case where each display (111 to 119) is implemented as a plurality of cabinets each including a plurality of LED modules and the cabinets are replaced, the display device (100) can read the second calibration data (25) from the flash memory provided for each cabinet and then identify the cabinet in which the second bit is 0. In this case, the display device (100) can identify that the corresponding cabinet is the replaced cabinet and perform a dehumidification operation on the replaced cabinet.

[0124] Meanwhile, in the case where each display (111 to 119) is implemented as a cabinet, even if one of the plurality of LED modules included in each cabinet is replaced, the display device (100) can perform a similar operation. For example, if some LED modules are replaced, the display device (100) can perform a dehumidification operation on the replaced LED module through the second calibration data (25) from the flash memory provided for each LED module. At this time, the display device (100) can perform a dehumidification operation only on the replaced LED module, and can perform a dehumidification operation on the entire cabinet to which the LED module belongs. Through this, the performance of the display device (100) can be further stabilized by removing moisture from the LED modules around the replaced LED module.

[0125] Meanwhile, according to the above-described example, each of the first bit (10-1) and the second bits (21-1 to 29-1) corresponds to one bit (e.g., LSB), but the present invention is not limited thereto. For example, each of the first calibration data (10) and the second calibration data (20) may include a plurality of first bits and a plurality of second bits. That is, unlike the example of FIG. 4, the rightmost (0, 1) in the first calibration data (10) may be set to a plurality of first bits, and the rightmost (0, 1) or (0, 0) in the second calibration data (20) may be set to a plurality of second bits. In this case, the remaining bits except for the two rightmost bits may store setting values ​​(e.g., brightness, color, contrast ratio, etc.) corrected through the calibration process.

[0126] In this way, when multiple first bits and multiple second bits are set, compared to when a single first bit (10-1) and second bit (21-1 to 29-1) are set, the error of the display device (100) incorrectly identifying the presence or absence of a replaced display can be effectively prevented.

[0127] For example, when a single first bit (10-1) and second bits (21-1 to 29-1) are set in the first calibration data (10) and the second calibration data (20), the following problem may occur. During the manufacturing stage of the replacement display (115), the second bit may be incorrectly set to 1 instead of 0. When the replacement display (115) is mounted on the display device (100), the display device (100) cannot identify the replaced display (115) as being the replaced display.

[0128] In the first calibration data (10) and the second calibration data (20), when a plurality of first bits and a plurality of second bits are set, and the plurality of first bits are (0, 1), even if the LSB is incorrectly set to 1 for the replacement display (115) as in the example described above, an error occurs only when the bits to the left of the LSB are incorrectly set to 0. That is, when a plurality of first bits and a plurality of second bits are set, an error occurs only when the plurality of second bits and the plurality of first bits all match each other, so the probability of error occurrence can be reduced.

[0129] According to one or more embodiments, the display device (100) may acquire a dehumidification mode for dehumidifying the replaced display (115) based on module data corresponding to the display (115) identified as being replaced, and control the replaced display (115) to operate in the acquired dehumidification mode.

[0130] According to FIG. 5, table (1') shows second calibration data (25') corresponding to the replaced display (115) among the second calibration data (20'). Here, the second bit (25-1') of the second calibration data (25') can be replaced from 0 to 1. The initial setting value (first calibration data) (10) corresponds to the same value as the value in table (1) shown in FIG. 4. In addition, the remaining bits, excluding the second bit (25-1') corresponding to the replaced display (115) among the first bit (10-1) and the second bits (21-1 to 29-1), also correspond to the same bits as the bits in table (1) shown in FIG. 4.

[0131] According to one or more embodiments, when a dehumidification operation corresponding to a dehumidification mode is completed, the display device (100) may update at least one second bit (25-1) corresponding to at least one display (115) for which the dehumidification operation has been completed to be identical to at least one first bit (10-1). At this time, the display device (100) may update the second bit (25-1) to 1 and set 1 as the updated second bit (25-1').

[0132] Accordingly, the second calibration data (21 to 24, 25', 26 to 29) corresponding to each of the plurality of displays (111 to 119) including the replaced display (115) can all match.

[0133] Meanwhile, even if at least one of the multiple displays (111 to 119) is replaced with a new display, the display device (100) can identify whether the display has been replaced by comparing calibration data to identify a display having a second bit of 0.

[0134] Meanwhile, as described above, the first calibration data (10) and the second calibration data (20) may each include a plurality of first bits and a plurality of second bits. In this case, the display device (100) may input data regarding the replacement history into each of the plurality of first bits and the plurality of second bits. For example, when the two rightmost bits in the first calibration data (10) and the second calibration data (20) are set to a plurality of first bits and a plurality of second bits, respectively, the rightmost bit (LSB) may be set as a bit for identifying whether or not to replace. At this time, the bit to the left of the rightmost bit may be set as a bit for inputting data regarding the replacement history.

[0135] For example, when dehumidification is completed for a display (115) identified as being replaced, the display device (100) may update the LSB corresponding to the replaced display (115) to 1 and input 1 for the bit on the left side of the LSB. Here, the input 1 may mean that the dehumidified display (115) corresponds to the replaced display.

[0136] Through this, if a migration failure occurs in relation to a later-replaced display (115), the display device (100) can easily identify the display (115) with a replacement history and help resolve the migration problem. Here, a migration failure may refer to a problem that may occur when adding or replacing a new display. For example, it may include a problem related to the physical connection of the display, a software compatibility problem, and a problem related to the calibration described above. When such a migration problem occurs, the display device (100) can resolve the problem by resetting the display (115) with a replacement history, etc.

[0137] Meanwhile, the display device (100) can identify the presence of a replaced display through module data (calibration data), and then acquire a dehumidification mode based on the module data of the replaced display (115). In order to acquire the dehumidification mode, the display device (100) can use other data in addition to the calibration data included in the module data.

[0138] FIG. 6 is a diagram illustrating manufacturing date data according to one or more embodiments of the present disclosure.

[0139] According to FIG. 6, at least one processor (130) can read date data stored in the flash memory (Module Cal Flash) of the fifth display (115) among the first to ninth displays (111 to 119). Here, the flash memory may correspond to a storage medium that stores the above-described calibration data. This flash memory may store module data corresponding to each of the plurality of displays (111 to 119). For example, the flash memory may store date data together with calibration data.

[0140] Here, the date data may include information regarding dates associated with each of the plurality of displays (111 to 119). For example, the date data may include manufacturing date data including manufacturing date information for each of the plurality of displays (111 to 119). Alternatively, the date data may include information regarding the effective use period of the plurality of displays (111 to 119). Here, the effective use period may refer to a range of periods during which each of the plurality of displays (111 to 119) is mounted on a display device (100) or the like and can normally perform an image display function. However, the present invention is not limited thereto.

[0141] According to one or more embodiments, at least one processor (130) may, when it is identified that at least one replaced display (115) exists, acquire a dehumidification mode for dehumidifying the at least one replaced display based on manufacturing date data included in module data corresponding to the at least one replaced display (115).

[0142] For example, at least one processor (130) may identify at least one replaced display (115) based on the initial setup data and module data as described above. At this time, at least one processor (130) may identify manufacturing date data included in the module data corresponding to at least one replaced display (115). Here, the manufacturing date data may include information on the date (year / month / day) on which each of the plurality of displays (111 to 119) was manufactured. Here, the date may be recorded as a plurality of bits expressed in binary, and the plurality of bits for the manufacturing date may be stored separately from the second calibration data in the flash memory described above.

[0143] Specifically, at least one processor (130) can compare the first calibration data and the second calibration data described above to identify at least one display having a second bit that is different from the first bit, and can identify the at least one display as a replaced display.

[0144] For example, referring to FIG. 4, at least one processor (130) can identify second calibration data (25) in which the second bit (25-1) among the second calibration data is 0 instead of 1. At this time, returning to FIG. 6, at least one processor (130) can identify the manufacturing date data stored together with the second calibration data (25) in the flash memory.

[0145] Meanwhile, at least one processor (130) can acquire a dehumidification mode for dehumidifying at least one replaced display (115) based on the identified manufacturing date data.

[0146] Specifically, at least one processor (130) can use the manufacturing date data to calculate the storage date of at least one replaced display (115).

[0147] According to one or more embodiments, at least one processor (130) can identify a storage period based on current date and manufacturing date data stored in memory, and acquire a mode corresponding to the storage period as a dehumidification mode.

[0148] For example, the memory may store the current date. In this case, the memory may store a system clock that provides the current date and time, and at least one processor (130) may identify the current date using the system clock stored in the memory.

[0149] Thereafter, at least one processor (130) can identify the storage period based on the current date and manufacturing date data stored in the memory. For example, at least one processor (130) can calculate the period of time elapsed from the manufacturing date corresponding to the manufacturing date data to the current date. Here, the elapsed period of time can be expressed in at least one unit of year, month, day, hour, minute, and second. For example, if the current date stored in the memory is July 1, 2024 and the manufacturing date is August 1, 2019, at least one processor (130) can calculate the period from August 1, 2019 to July 1, 2024, thereby calculating a period of 4 years and 11 months. At least one processor (130) can identify 4 years and 11 months as the storage period. As another example, if the current date stored in the memory is July 1, 2024 and the manufacturing date is June 1, 2019, at least one processor (130) can identify the storage period as 5 years and 1 month.

[0150] Meanwhile, at least one processor (130) may acquire a mode corresponding to the identified storage period as a dehumidification mode. Here, the mode may correspond to an operation mode for dehumidifying at least one replaced display (115).

[0151] For example, if some displays of a display device (100) are replaced with new displays (or replacement displays), and the new displays have been stored in a warehouse or the like for a long period of time, they may absorb a large amount of moisture depending on the environment of the warehouse or the like. In this case, the replaced displays may need to be dehumidified in a relatively high-intensity dehumidification mode. On the other hand, if the new displays have been stored in a warehouse or the like for a relatively short period of time, they may absorb a relatively small amount of moisture. In this case, the replaced displays may need to be dehumidified quickly in a relatively low-intensity dehumidification mode.

[0152] For example, at least one processor (130) may acquire a mode in which dehumidification takes a long time in proportion to the storage period as a dehumidification mode. Alternatively, at least one processor (130) may acquire a mode in which high brightness is maintained for a long time in proportion to the storage period as a dehumidification mode. Alternatively, at least one processor (130) may acquire a mode including a number of dehumidification operation steps in proportion to the storage period as a dehumidification mode. However, the present invention is not limited thereto.

[0153] For the example described above, at least one processor (130) can use the storage period to calculate the dehumidification time, the time for which high brightness is maintained, or the number of dehumidification operation steps.

[0154] Here, the dehumidification operation step (or step) may include at least one preheating step and at least one aging pattern step.

[0155] Here, the preheating step may correspond to a step of gradually heating the interior of at least one replaced display (115) to evaporate moisture. For example, at least one processor (130) may control at least one replaced display (115) to output an image with a gradually increased brightness from a low brightness.

[0156] Meanwhile, the aging pattern step may correspond to a step of repeatedly outputting a specific pattern for a certain period of time for at least one replaced display (115). Here, the specific pattern may include white (Full-white) and black (Balck). For example, at least one processor (130) may control at least one replaced display (115) to output a white screen for a certain period of time and then display a black screen after a certain period of time has elapsed, and this process may be repeatedly performed. For example, the at least one processor (130) may continue the preheating step for a longer period of time as the storage period increases, and may output the white and black screens repeatedly more times.

[0157] Meanwhile, at least one processor (130) may compare the storage period with a specific period to obtain one of several dehumidification modes.

[0158] FIG. 7 is a diagram illustrating a dehumidification mode according to one or more embodiments of the present disclosure.

[0159] According to Fig. 7, Table (2) shows the dehumidification mode and dehumidification operation according to the storage period.

[0160] According to one or more embodiments, the dehumidification mode is one of a plurality of dehumidification modes distinguished based on at least one predetermined period of time, and the display device (100) can obtain the dehumidification mode by comparing the storage period with the at least one predetermined period of time.

[0161] Here, at least one predetermined period may correspond to a predetermined period of time to distinguish multiple dehumidification modes. The predetermined period may be stored in memory according to user or manufacturer settings, and may be reset to a different period after being stored in memory.

[0162] Meanwhile, multiple dehumidification modes may be distinguished based on the aforementioned fixed period. For example, if the fixed period is 5 years, the multiple dehumidification modes may include a first mode corresponding to a storage period of less than 5 years and a second mode corresponding to a storage period of 5 years or more, and the first mode and the second mode may be distinguished based on the fixed period of 5 years.

[0163] Specifically, the first mode and the second mode may each include at least one preheating step and one aging pattern step.

[0164] For example, the first mode may include a 10-stage preheating stage and a 120-hour aging pattern stage. Each preheating stage may be a stage that outputs an image from low brightness to high brightness. In the preheating stage, the replaced display may be gradually heated by outputting an image at low brightness and then gradually outputting an image at high brightness. The 120-hour aging pattern stage included in the first mode may be a stage that outputs a full-white and a black screen. For example, in the aging pattern stage, the replaced display may output a white screen for 2 hours and then a black screen for 1 hour as a basic unit operation, and this basic unit operation may be repeated 40 times. In this way, the replaced display in the aging pattern stage may perform a dehumidifying operation of the aging pattern stage for a total of 120 hours.

[0165] Meanwhile, the second mode may include an 11-step preheating step and a 120-hour aging pattern step. The 120-hour aging pattern step may be the same as the first mode. However, this is not limited to the second mode, and unlike the first mode, the aging pattern mode may be performed for a longer period of time (e.g., 150 hours). For example, the replaced display may repeat the basic unit operation described above 50 times in the second mode.

[0166] Meanwhile, the replaced display can perform an 11-stage preheating mode by adding one more stage in addition to the 10-stage preheating stage included in the 1st mode in the 2nd mode.

[0167] Through this, the display device (100) can set a dehumidification mode based on the identified storage period by comparing the storage period with a preset period (or reference period). Accordingly, the display device (100) can automatically perform an appropriate dehumidification operation according to the storage period of the replaced display, thereby increasing user convenience.

[0168] Meanwhile, the aforementioned fixed period can be set to multiple periods. For example, a user or manufacturer can set multiple different periods as the fixed period. For example, unlike the example illustrated in Figure 7, a user or manufacturer can set the fixed period to two years and five years.

[0169] In this case, the multiple dehumidification modes may correspond to multiple modes divided by multiple fixed periods (2 years, 5 years). For example, the display device (100) may operate in the first mode when the storage period of the replaced display is less than 2 years, in the second mode when the storage period is 2 years or more but less than 5 years, and in the third mode when the storage period is 5 years or more. As in the case where the fixed period is one period, the first to third modes may correspond to modes in which the preheating step and the aging pattern step are each set differently depending on the storage period. However, the present invention is not limited thereto.

[0170] Accordingly, since the fixed period can be set to a variety of periods, the user or manufacturer can set the mode in more detail according to the environmental conditions of the place where the replaced display was stored or according to the storage period, so that the replaced display can be dehumidified more efficiently.

[0171] Meanwhile, the display device (100) can identify whether the display is to be replaced as described above, and then acquire a dehumidification mode based on the storage period of the replaced display and operate according to the acquired dehumidification mode. To this end, at least one processor included in the display device (100) can perform several data processing processes.

[0172] FIG. 8 is a diagram illustrating at least one processor according to one or more embodiments of the present disclosure.

[0173] According to FIG. 8, at least one processor may include a T-CON (Timing controller) (131) and an AP (Application Processor) (132). Here, the T-CON (131) may include an FPGA (Field-Programmable Gate Array) (131-1) and a microprocessor (131-2).

[0174] Here, the T-CON (131) can play a role in controlling the time at which signals are provided to the multiple displays (110). Specifically, the input image signal can be converted into a signal for the multiple displays (110) to display an image and the signal can be transmitted at an appropriate time. However, the present invention is not limited thereto, and data necessary for the operation of the display device (100) can be read from the flash memory of each of the multiple displays (111 to 119), and data provided from an external processor device can be written to the flash memory.

[0175] Specifically, the T-CON (131) may include an FPGA (131-1) and a microprocessor (131-2). Here, the FPGA (131-1) may correspond to a semiconductor device including a programmable internal circuit. Meanwhile, the microprocessor (131-2) may correspond to a single integrated circuit for performing various computational functions mainly on digital signals. For example, the FPGA (131-1) may be electrically connected to a plurality of displays (111 to 119). In addition, the FPGA (131-1) may be programmed to perform operations necessary for executing a dehumidification mode for at least one display in which the display device (100) has been replaced, and may include a circuit designed according to such programming. The microprocessor (131-2) can exchange digital signals with the FPGA (131-1) and perform an operation to perform a dehumidification mode for at least one display in which the display device (100) has been replaced.

[0176] Meanwhile, the AP (132) is located on the main board of the display device (100) and can receive a digital signal from the microprocessor (131-2). The AP (132) can perform an operation on the digital signal provided from the microprocessor (131-2) and provide the microprocessor (131-2) with a signal necessary for the operation of the display device (100). Although Fig. 8 illustrates an example in which at least one processor is composed of one T-CON (131) and an AP (132), this is only an example, and a plurality of T-CONs (131) and a plurality of APs (132) can constitute a processor to perform operations necessary for the operation of the display device (100).

[0177] Accordingly, various types of processors (FPGA (131-1), microprocessor (131-2), AP (132)) included in at least one processor can organically operate to control the operation of the display device (100). However, the present invention is not limited thereto.

[0178] For example, when the display device (100) is activated, the FPGA (131-1) can read calibration data from the flash memory of each of the plurality of displays (111 to 119). Thereafter, the FPGA (131-1) can identify a specific bit (second bit) value for replacement recognition of at least one display and compare it with a bit (first bit) according to the initial setting to identify whether at least one display is to be replaced.

[0179] If the second bit of the calibration data read by the FPGA (131-1) is the same as the bit according to the initial setting, the display device (100) can operate in normal mode. On the other hand, if the second bit of the calibration data read by the FPGA (131-1) is different from the bit according to the initial setting, date data can be read from the flash memory of at least one display corresponding to the second bit.

[0180] Thereafter, the FPGA (131-1) can provide data on whether at least one display is replaced, location data of the replaced display, and date data to the microprocessor (131-2). The microprocessor (131-2) can provide the received data to the AP (132) located on the main board. Here, the location data may be data that can be identified by the FPGA (131-1). The FPGA (131-1) can identify the location data from calibration data having a second bit that is different from the bit according to the initial setting data. For example, among a plurality of displays (111 to 119) arranged 3x3 as shown in FIG. 1, if a display (115) in 2 rows and 2 columns corresponds to a replaced display, the FPGA (131-1) can identify position data including information that the replaced display (115) is arranged in 2 rows and 2 columns from calibration data having a second bit different from the bit according to the initial setting data. The position data may correspond to data expressed in binary, similar to the calibration data.

[0181] Next, the AP (132) can process the data provided from the microprocessor (131-2). Specifically, when the AP (132) receives the above data, it determines that the dehumidification mode should be executed instead of the normal mode, and can identify the storage period for which the dehumidification mode should be executed. The AP (132) can compare the production date data of the replaced display with the current date and then calculate the total storage period. Thereafter, the AP can execute a dehumidification mode pattern that suits the conditions (e.g., storage period conditions, etc.) only for the replaced display through the location data of the replaced display. When the dehumidification mode is completed, the microprocessor (131-2) of the T-CON (131) can transmit a control signal to the FPGA (131-1), so that the FPGA (131-1) can update the replacement recognition bit (second bit) of the display in the flash memory of the replaced display from 0 to 1.

[0182] Although the operations of the T-CON (131) and the AP (132) have been specifically described above, they are not limited thereto, and the T-CON (131) and the AP (132) can perform various operations necessary to allow the display device (100) to dehumidify a replaced display, including the operations of the display device (100) described in the present disclosure.

[0183] FIG. 9 is a diagram illustrating a deactivation operation according to one or more embodiments of the present disclosure.

[0184] According to FIG. 9, among the plurality of displays (111 to 119) included in the display device (100), the remaining plurality of displays (111 to 114, 116 to 119) excluding the replaced display (115) may be in a dark state.

[0185] According to one or more embodiments, when the display device (100) identifies that at least one replaced display (115) exists, the display device (100) may deactivate at least one display (111 to 114, 116 to 119) other than the at least one replaced display (115) among the plurality of displays (111 to 119) while operating in a dehumidifying mode.

[0186] Here, the display device (100) disabling at least one remaining display (111 to 114, 116 to 119) may mean controlling at least one remaining display (111 to 114, 116 to 119) to display a dark screen (e.g., a black screen), may mean blocking a video signal to at least one remaining display (111 to 114, 116 to 119), and may mean blocking power supplied to at least one remaining display (111 to 114, 116 to 119).

[0187] The display device (100) has the effect of reducing power consumption by executing a dehumidification mode only for the replaced display (115) by keeping the remaining at least one display (111 to 114, 116 to 119) in an inactive state when at least one replaced display (115) exists.

[0188] Meanwhile, the display device (100) may display a notification screen to inform the user that the dehumidification mode is in progress while the dehumidification mode is being executed for the replaced display (115).

[0189] FIG. 10 is a diagram illustrating an operation of displaying progress information according to one or more embodiments of the present disclosure.

[0190] According to FIG. 10, when the display device (100) operates in a dehumidification mode for the replaced display (115), the text 'Dehumidifying replacement module (26%)' may be displayed on the lower display (111, 114, 117) among the remaining plurality of displays (111 to 114, 116 to 119).

[0191] According to one or more embodiments, the display device (100) can control at least one display (111 to 114, 116 to 119) other than at least one replaced display (115) among the plurality of displays (111 to 119) to display a screen including dehumidification mode progress information.

[0192] Here, the dehumidification mode progress information may include information that the display device (100) has a replaced display among the plurality of displays (111 to 119) and that the dehumidification mode is automatically in progress for the replaced display, and may include information on the progress according to the dehumidification mode or information on the position of the display where dehumidification is in progress. Here, the information on the progress may be displayed as the remaining time or progress rate (%) until the dehumidification of the replaced display (115) is completely completed. Here, the remaining time or progress rate may be calculated based on humidity. That is, the display device (100) may detect the humidity of the replaced display (115) in real time through at least one sensor separately provided in the display device (100), and may calculate the remaining time or progress rate based on the initial humidity immediately after the display (115) is replaced.

[0193] Meanwhile, Fig. 10 shows an example in which the text 'Dehumidifying replacement module (26%)' is displayed as dehumidifying mode progress information, but this is only an example, and various texts, pictures, videos, etc. containing information that the dehumidifying mode is in progress may be displayed, and various texts containing information indicating the location of the display where dehumidification is in progress may be displayed.

[0194] For example, when the display device (100) performs a dehumidification mode for a replaced display (115), the display device (100) can control the lower displays (111, 114, 117) among the remaining plurality of displays (111 to 114, 116 to 119) to display dehumidification mode progress information. At this time, the display device (100) can deactivate the plurality of displays (112, 113, 116, 118, 119) among the remaining plurality of displays (111 to 114, 116 to 119) except for the lower displays (111, 114, 117) on which progress information is displayed.

[0195] Meanwhile, although FIG. 10 illustrates a state in which progress information is displayed on the lower displays (111, 114, 117), this is merely an example, and the progress information may be displayed in various locations among the remaining plurality of displays (111 to 114, 116 to 119). In addition, the progress information may be displayed on one of the remaining plurality of displays (111 to 114, 116 to 119), or may be displayed on multiple displays among the remaining plurality of displays (111 to 114, 116 to 119). In addition, the progress information may be displayed by moving the location over time within the range of the remaining plurality of displays (111 to 114, 116 to 119).

[0196] FIG. 11 is a flowchart illustrating a method for controlling a display device according to one or more embodiments of the present disclosure.

[0197] According to FIG. 11, when the display device (100) is activated, the display device can identify whether there is at least one display among the plurality of displays that was replaced before the display device was activated, based on the initial setting data and the module data preset for each of the plurality of displays (S1110).

[0198] According to one or more embodiments, the display device (100) compares initial setup data with module data corresponding to each of the plurality of displays, and if module data corresponding to at least one display among the module data corresponding to each of the plurality of displays is identified as different from the initial setup data, the display device can identify at least one display as at least one replaced display, and identify that at least one replaced display exists.

[0199] Next, if it is identified that at least one replaced display exists, a dehumidification mode for dehumidifying at least one replaced display can be acquired based on module data corresponding to at least one replaced display (S1120).

[0200] According to one or more embodiments, when the display device (100) identifies that at least one replaced display exists, the display device (100) may acquire a dehumidification mode for dehumidifying the at least one replaced display based on manufacturing date data included in module data corresponding to the at least one replaced display.

[0201] According to one or more embodiments, the display device (100) can identify a storage period based on current date and manufacturing date data, and acquire a mode corresponding to the storage period as a dehumidification mode.

[0202] Next, at least one replaced display can be controlled to operate in the acquired dehumidification mode (S1130).

[0203] According to one or more embodiments, when the display device (100) identifies that at least one replaced display exists, the display device (100) may deactivate at least one display, other than the at least one replaced display, among the plurality of displays while operating in a dehumidifying mode.

[0204] Through this, when a defect occurs in some of the displays of the display device (100) during use and a display that has been stored for a long time is replaced, the replaced display can be automatically recognized and the corresponding dehumidification mode can be automatically operated. Accordingly, when replacing some of the displays, it is possible to prevent a worker from accidentally turning on the display device (100) without removing moisture, thereby preventing screen transient problems such as LED defects. In addition, it is possible to reduce the inconvenience of the worker having to manually execute the dehumidification mode, and it is possible to increase convenience by automatically recognizing the display storage period and executing the dehumidification mode according to the conditions.

[0205] The various methods described in FIG. 11 can be performed by a display device having the configuration shown in FIG. 2, but are not necessarily limited thereto, and can also be performed by a display device having various configurations.

[0206] Meanwhile, in Fig. 11, the order is mapped for all steps for convenience of explanation, but it is of course not necessarily limited to the order of steps that are not related to the order or can be performed in parallel.

[0209] Additionally, the methods according to at least some of the various embodiments of the present disclosure described above may also be performed through an embedded server provided in the display device, or an external server of at least one of the display devices.

Here, the 'non-transitory storage medium' only means that it is a tangible device and does not include a signal (e.g., electromagnetic wave), and this term does not distinguish between cases where data is stored semi-permanently and cases where it is temporarily stored in the storage medium. No. For example, a 'non-transitory storage medium' may include a buffer in which data is temporarily stored.
