[0218] Modules 1,2,3,5,6,7,9,10,11,13,14,15,17,18,19,21,22,23 can be level 1. Modules 4, 8, 12, 16, 20, 24 can be level 2.

[0219] For example, the level of each of the multiple display modules can be set by the user.

[0220] For example, the level of each of the plurality of display modules can be automatically determined. The level of each of the plurality of display modules can be determined based on the number or orientation of the connected display modules.

[0221] If no additional display modules are connected horizontally to a particular display module, the display device (200) may determine the particular display as the first level.

[0222] If the number of display modules connected to a specific display module is less than three and the display modules are not connected in a horizontal square, the display device (200) can determine the specific display as the first level.

[0223] If an additional display module is connected in a horizontal square shape to a specific display module, the display device (200) can determine the specific display as the second level.

[0224] If the number of display modules connected to a specific display module is three or more or the display modules are connected in a horizontal square, the display device (200) can determine the specific display as the second level.

[0225] Example (930) may represent a calculation process for accumulating location information. The location information (931) may be location information generated by the fourth module. The location information (931) may indicate the locations of the first to fourth modules.

[0226] Location information (932) may be location information generated by the eighth module. Location information (932) may indicate the locations of the first to eighth modules.

[0227] Location information (933) may be location information generated in the 12th module. Location information (933) may indicate the locations of the 1st to 12th modules.

[0228] The 12th module can transmit location information (933) to the electronic device (100).

[0229] Location information (934) may be location information generated in the 24th module. Location information (934) may indicate the locations of the 21st to 24th modules.

[0230] Location information (935) may be location information generated in the 20th module. Location information (935) may indicate the locations of the 17th to 20th modules.

[0231] Location information (936) may be location information generated in the 16th module. Location information (936) may indicate the locations of the 13th to 16th modules.

[0232] The 16th module can transmit location information (936) to the electronic device (100).

[0233] A specific display module can combine two pieces of location information to generate a single piece of location information. For example, the eighth module can receive location information (#1, 2, 3, 4*) from the fourth module. The eighth module can obtain location information (#5, 6, 7, 8*) that it generated. The eighth module can combine location information (#1, 2, 3, 4*) and location information (#5, 6, 7, 8*) to obtain a single piece of location information (#1, 2, 3, 4*#5, 6, 7, 8*).

[0234] In a combined operation, location information generated by the module itself can be given priority. A specific display module can give priority to location information received from another display module. Giving priority may involve placing the code or data representing the location information first.

[0235] In the embodiment of FIG. 9, the electronic device (100) can identify at least one main group based on location information and obtain a target resolution.

[0236] Figure 10 is a drawing showing an example of a major group.

[0237] Referring to FIG. 10, the electronic device (100) can generate location information from a plurality of display modules included in the display device (200). There may be a plurality of location information. The location information may be information indicating the location of each of the plurality of display modules, as shown in the table (850) of FIG. 8. The location information may be accumulated location information, as shown in the embodiment (930) of FIG. 9.

[0238] The electronic device (100) can obtain (or generate) structural information based on location information indicating the locations of a plurality of display modules. The structural information may be information indicating the locations and / or structures of the plurality of display modules. The location information may be partial information indicating the locations of each or at least some of the plurality of display modules. The structural information may be overall information indicating the locations of all of the plurality of display modules.

[0239] The electronic device (100) can divide a plurality of display modules into at least one main group.

[0240] Example (1010) may represent an operation for determining a single main group (1001). The electronic device (100) may classify all multiple display modules into a single main group (1001) based on structural information. The electronic device (100) may determine an auxiliary group based on a vertical direction. If the connection direction is vertical, the electronic device (100) may classify them into the same auxiliary group.

[0241] Modules 1 to 4 can be classified into a first auxiliary group (1011).

[0242] Modules 5 through 8 can be classified into a second auxiliary group (1012).

[0243] Modules 9 to 12 can be classified into a third auxiliary group (1013).

[0244] Modules 13 to 16 can be classified into the 4th auxiliary group (1014).

[0245] Modules 17 to 20 can be classified into the 5th auxiliary group (1015).

[0246] Modules 21 to 24 can be classified into the 6th auxiliary group (1016).

[0247] In the embodiment (910) of FIG. 9, the electronic device (100) can determine an auxiliary group based on a first symbol (eg #) and a second symbol (eg *). The electronic device (100) can classify modules existing between the first symbol (eg #) and the second symbol (eg *) into one auxiliary group. The criteria for classifying auxiliary groups can be equally applied to the embodiments (1020, 1030). Duplicate explanations are omitted.

[0248] Example (1020) may represent an operation of determining two main groups. The electronic device (100) may divide a plurality of display modules into two main groups based on structural information.

[0249] For example, the electronic device (100) may determine the number of main groups based on the received location information. For example, in the embodiment (910) of FIG. 9, the electronic device (100) may receive first location information from the 12th module and second location information from the 16th module. The electronic device (100) may determine the display module included in the first location information as the first main group (1021) and determine the display module included in the second location information as the second main group (2022).

[0250] For example, the electronic device (100) can determine a plurality of display modules into two main groups based on a preset classification method (e.g., left and right).

[0251] Example (1030) may represent an operation of determining three main groups (1031, 1032, 1033). The electronic device (100) may divide a plurality of display modules into three main groups (1031, 1032, 1033) based on structural information.

[0252] According to various embodiments, the electronic device (100) may divide a plurality of display modules into a plurality of main groups. The number of main groups may be changed according to user settings or criteria.

If the number of main groups is one, the electronic device (100) may provide the image to the display device (200) without dividing the image.

[0256] Embodiment (1120) of Fig. 11 may represent an operation of displaying an image in embodiment (1020) of Fig. 10. The electronic device (100) may divide the image into the number of main groups (2). Based on the division result, the electronic device (100) may obtain a first divided image and a second divided image. The electronic device (100) may provide the divided image to the display device (200). The electronic device (100) may provide the first divided image to the first main group (1121) and the second divided image to the second main group (1122).

[0257] The embodiment (1130) of FIG. 11 may represent an operation of displaying an image in the embodiment (1030) of FIG. 10. The electronic device (100) may divide the image into the number of main groups (three). The electronic device (100) may provide the divided images to the display device (200). Based on the division results, the electronic device (100) may obtain a first divided image, a second divided image, and a third divided image. The electronic device (100) may provide the first divided image to the first main group (1131), the second divided image to the second main group (1132), and the third divided image to the third main group (1133).

[0258] Figure 12 is a diagram showing the operation of dividing an image into major groups.

[0259] Referring to the embodiment (1210) of FIG. 12, the display device (200) may include 1 to 24 display modules. The display device (200) may obtain identification information for each of the plurality of display modules. The identification information for each module may be 1 to 24. The identification information may include information that can identify each module. The identification information may include at least one of a unique number or a model number of the display module.

[0260] Identification information may be included in location information. A description of this is provided in FIGS. 8 and 9.

[0261] Referring to embodiment 1220 of FIG. 12, the electronic device (100) can distinguish between a first main group (1221) and a second main group (1222) based on identification information included in location information. The electronic device (100) can group identification information of each of the first to twelfth display modules into the first main group (1221). The electronic device (100) can group identification information of each of the thirteenth to twenty-fourth display modules into the second main group (1222).

[0262] Figure 13 is a diagram showing the operation of assigning address information to a major group.

[0263] Referring to embodiment (1310) of FIG. 13, the electronic device (100) can receive information indicating the positions of 24 display modules from the display device (200).

[0264] Referring to embodiment 1320 of FIG. 13, the electronic device (100) can determine at least one main group based on location information. The electronic device (100) can classify (or divide) multiple display modules into two main groups. The electronic device (100) can classify a first main group (1321) and a second main group (1322) based on location information.

[0265] Referring to embodiment 1330 of FIG. 13, the electronic device (100) may assign new address information based on the distinguished first main group and second main group. The address information may be information indicating the location of a specific display module. The address information may be different from the unique identification information described in FIG. 12. The address information may be newly generated information based on the main group.

[0266] A plurality of display modules included in the display device (200) can be specified based on new address information generated by the electronic device (100). For example, the address information of the first module may be 134. Description of the address information of other modules is omitted.

[0267] Figure 14 is a diagram showing an operation for obtaining upscaling ratio information.

[0268] The electronic device (100) can identify (or obtain) a target resolution based on structural information. The electronic device (100) can determine the target resolution of the image to be provided based on the structural information. This is because the size of the displayed image may vary depending on the structural information. The electronic device (100) can obtain upscaling ratio information based on the preset resolution and the target resolution. The resolution may represent a ratio of width to height.

[0269] Referring to the embodiment (1410) of FIG. 14, it is assumed that the preset resolution is 1:1 (vertical:horizontal). The electronic device (100) can determine the size of the image to be displayed by the display device (200) based on the structural information. The electronic device (100) can determine the target resolution based on the structural information. The electronic device (100) can obtain the target resolution of 4:6 (vertical:horizontal).

[0270] The vertical:horizontal ratios that indicate resolution can include the concept of absolute length. For example, 1:1 resolution and 2:2 resolution can represent the same ratio. However, 1:1 resolution and 2:2 resolution can represent different lengths. A 2:2 resolution can represent a greater length than a 1:1 resolution.

[0271] The electronic device (100) can obtain upscaling ratio information (4:6) based on a preset resolution (1:1) and a target resolution (4:6). The upscaling ratio information can indicate a coefficient for each of a plurality of display modules to scale an image.

[0272] Upscaling ratio information (4:6) may include vertical conversion ratio information (x4) and / or horizontal conversion ratio information (x6).

[0273] The image can be converted based on the upscaling ratio information (4:6). The image can be expanded 4 times horizontally and 6 times vertically.

[0274] Referring to the embodiment (1420) of FIG. 14, it is assumed that the preset resolution is 2:3 (vertical:horizontal). The electronic device (100) can determine the size of the image to be displayed by the display device (200) based on the structural information. The electronic device (100) can determine the target resolution based on the structural information. The electronic device (100) can obtain the target resolution of 4:6 (vertical:horizontal).

[0275] The electronic device (100) can obtain upscaling ratio information (2:2) based on a preset resolution (2:3) and a target resolution (4:6). The upscaling ratio information can indicate a coefficient for each of a plurality of display modules to scale an image.

[0276] Upscaling ratio information (2:2) may include vertical conversion ratio information (x2) and / or horizontal conversion ratio information (x2).

[0277] The image can be converted based on the upscaling ratio information (2:2). The image can be expanded twice in width and twice in height.

[0278] Fig. 15 is a diagram showing an operation of displaying a converted image using upscaling ratio information.

[0279] Referring to FIG. 15, the display device (200) can store upscaling ratio information (S1545). The previous steps related to this can be applied to the operations of FIGS. 6 and 7.

[0280] The electronic device (100) can obtain an input image (S1550).

[0281] The electronic device (100) can identify the number of at least one main group and the area of ​​at least one main group. The electronic device (100) can obtain main group information including the number of at least one main group and the area of ​​at least one main group (S1555).

[0282] A region may indicate the relative position of a specific main group. For example, in the embodiment (1020) of FIG. 10, the region of the first main group (1021) may be on the left, and the region of the second main group (1022) may be on the right.

[0283] A region may represent an absolute location of a specific main group. For example, in the embodiment (1020) of FIG. 10, the region of the first main group (1021) may be the first region (x1, y1 to x12, y12), and the region of the second main group (1022) may be the second region (x13, y13 to x24, y24).

[0284] A description of the operation of segmenting and providing images based on the main group is described in FIGS. 10 and 11.

[0285] The electronic device (100) can segment the input image based on the number of main groups and the area (e.g., left, right) of the main groups. The electronic device (100) can segment the input image by the number of main groups (e.g., 2). The electronic device (100) can segment the input image based on the area (left, right) of the main groups.

[0286] The electronic device (100) can obtain a segmented image based on main group information and an input image (S1560). If there is only one main group, as in the embodiments (1010) of FIG. 10 and (1110) of FIG. 11, the input image may not be segmented.

[0287] The electronic device (100) can transmit a segmented image to the display device (200) (S1565). The segmented image may be a plurality of segmented images.

[0288] If the segmentation operation is not performed, step S1656 may be described as transmitting the input image. Duplicate description is omitted below.

[0289] The display device (200) can receive a segmented image from the electronic device (100). The display device (200) can obtain an extracted image based on upscaling ratio information and the segmented image (S1570).

[0290] Each of the plurality of display modules can identify its own position through structural information. Each of the plurality of display modules can obtain an extracted image corresponding to its own position. The segmented image may be an image for at least one display module corresponding to the main group. A specific display module can extract a partial image that it should display. The extracted partial image may be described as an extracted image. A specific display module can extract an image area corresponding to its own position. The extracted image may include an area that the specific display module should display.

[0291] A specific display module can obtain an extraction image including information about a partial region that a specific display module should display among the entire region of a segmented image based on structural information.

[0292] The display device (200) can obtain a converted image by scaling the extracted image based on upscaling ratio information (S1575). Scaling may include an operation of changing the resolution (or size) of the input image. The display device (200) can expand the extracted image based on the upscaling ratio information. The display device (200) can obtain a converted image by changing the horizontal size (or length) and / or vertical size (or length) of the extracted image.

[0293] The display device (200) can display a conversion image corresponding to each of a plurality of display modules based on structural information (S1580). A specific display module can display a conversion image including an area that it should display.

[0294] In one embodiment, the operations of obtaining an extracted image and the operations of obtaining a converted image may be performed for each of a plurality of display modules.

[0295] According to one embodiment, the operation of obtaining an extracted image and the operation of obtaining a converted image are performed once by a processor or control unit representing the display device (200), and the converted image can be transmitted to each of a plurality of display modules.

[0296] Fig. 16 is a drawing showing an operation of providing a segmented image to a display device (200).

[0297] Referring to FIG. 16, the electronic device (100) can obtain an input image (1600). The electronic device (100) can obtain a first segmented image (1601) and a second segmented image (1602) based on the number of main groups (2) and the area (left, right) of the main groups.

[0298] The electronic device (100) can provide (or transmit) the first segmented image (1601) to the first main group. The electronic device (100) can provide (or transmit) the second segmented image (1602) to the second main group.

[0299] The electronic device (100) can classify the modules (4, 8, 12, 16, 20, 2 4) connected in a horizontal direction among the plurality of display modules included in the main group as host modules, and the modules connected in a vertical direction can be classified as sub-modules (1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 14, 15, 17, 18, 19, 21, 22, 23).

[0300] The vertical or horizontal directions described above and below may be replaced with preset directions. The vertical or horizontal directions are merely examples, and the operations of the present invention may be applied to multiple display modules arranged in various arrangements.

[0301] The electronic device (100) can provide the first segmented image (1601) to a first host module (1611) among a plurality of display modules included in the first main group. The electronic device (100) can transmit the first segmented image (1601) to a representative module (e.g., a 12th module) among the first host modules (1611). The first host module (1611) can transmit the first segmented image (1601) to a first sub-module (1612).

[0302] For example, a specific display module (e.g., a fourth module) included in a first host module (1611) can transmit a first segmented image (1601) to a sub-module (e.g., a first module, a second module, a third module) corresponding to a specific plurality of display modules.

[0303] The electronic device (100) can provide the second segmented image (1602) to a second host module (1621) among a plurality of display modules included in the second main group. The electronic device (100) can transmit the second segmented image (1602) to a representative module (e.g., module 16) among the second host modules (1621). The second host module (1621) can transmit the second segmented image (1602) to a second sub-module (1622).

[0304] For example, a specific display module (e.g., module 24) included in a second host module (1621) can transmit a second segmented image (1602) to a sub-module (e.g., module 21, module 22, module 23) corresponding to a specific plurality of display modules.

[0305] Fig. 17 is a diagram illustrating an operation of changing structural information according to one embodiment.

[0306] Referring to the embodiment (1710) of FIG. 17, the display device (200) may include first to twenty-four display modules. The structure of the display device (200) may be changed. The reasons for the change may vary.

[0307] For example, users can change the layout of existing display modules.

[0308] For example, an additional display module may be placed in addition to the existing display module. A description of this is provided in FIGS. 17 and 18.

[0309] For example, the existing display module can be excluded. A description of this is provided in Fig. 19.

[0310] Referring to embodiment (1720) of FIG. 17, it is assumed that display modules 25 to 32 are additionally arranged. The electronic device (100) can obtain structural information including the positions of the changed display modules. The electronic device (100) can obtain new structural information to replace existing structural information. The electronic device (100) can obtain new structural information by updating existing structural information. The structural information prior to the update can be described as first structural information, and the structural information after the update can be described as second structural information.

[0311] The electronic device (100) can obtain new upscaling ratio information based on the updated structural information.

[0312] The electronic device (100) can acquire a new target resolution based on the updated structural information. The new target resolution may be described as an updated target resolution. The target resolution prior to the update may be described as a first target resolution (e.g., 4:6), and the target resolution after the update may be described as a second target resolution (e.g., 4:8).

[0313] The electronic device (100) may record new upscaling ratio information as updated upscaling ratio information. Upscaling ratio information prior to the update may be recorded as first upscaling ratio information, and upscaling ratio information after the update may be recorded as second upscaling ratio information (4:8).

[0314] Referring to Example (1730), the display device (200) can display an image based on updated upscaling ratio information.

[0315] Fig. 18 is a diagram showing an operation of changing structural information according to one embodiment.

[0316] Embodiment (1810) of Fig. 18 may correspond to embodiment (1710) of Fig. 17. Duplicate explanation is omitted.

[0317] Referring to embodiment 1820 of FIG. 18, it is assumed that display modules 25 to 32 are additionally arranged. The electronic device (100) can obtain structural information including the positions of the changed display modules. The electronic device (100) can obtain new structural information to replace existing structural information. The electronic device (100) can obtain new structural information by updating existing structural information. The structural information prior to the update can be described as first structural information, and the structural information after the update can be described as second structural information.

[0318] The electronic device (100) can obtain new upscaling ratio information based on the updated structural information.

[0319] The electronic device (100) can acquire a new target resolution based on the updated structural information. The new target resolution may be described as an updated target resolution. The target resolution before the update may be described as a first target resolution (e.g., 4:6), and the target resolution after the update may be described as a second target resolution (e.g., 4:6). The first target resolution (e.g., 4:6) and the second target resolution (e.g., 4:6) may be the same.

[0320] The electronic device (100) can obtain a target resolution using a preset resolution limit. The preset resolution limit may include a user-set vertical:horizontal ratio restriction when providing an image. For example, the preset resolution limit may indicate a 2:3 (vertical:horizontal) ratio. The preset resolution limit may include a ratio concept. Therefore, the preset resolution limit (2:3) means that the vertical:horizontal ratio is 2:3, and may not indicate an absolute length.

[0321] If the preset resolution limit is exceeded during the calculation process, the electronic device (100) can determine a target display module among multiple display modules on which to display the image. This is because, if the resolution is exceeded, the image cannot be displayed on all display modules. The electronic device (100) can identify the target display module based on the center position.

[0322] The preset resolution limit may include an upper limit ratio (e.g., 2:3) and a lower limit ratio (e.g., 1:1). When the lower limit ratio (e.g., 1:1) is applied, the display device (200) cannot display an image with a longer vertical length.

[0323] Referring to Example (1820), the electronic device (100) can identify the target display module as the 5th to 28th module. The criteria for identifying the target display module can be changed by user settings.

[0324] The electronic device (100) may record new upscaling ratio information as updated upscaling ratio information. Upscaling ratio information prior to the update may be recorded as first upscaling ratio information, and upscaling ratio information after the update may be recorded as second upscaling ratio information (4:6).

[0325] Referring to Example (1830), the display device (200) can display an image based on updated upscaling ratio information.

[0326] In Figure 18, the resolution limitation is described as being applied when the layout of the display modules is changed. However, the resolution limitation can always be applied at the stage of setting the initial target resolution.

[0327] FIG. 19 is a diagram illustrating an operation for changing structural information according to one embodiment.

[0328] Embodiment (1910) of Fig. 19 may correspond to embodiment (1710) of Fig. 17. Duplicate explanation is omitted.

[0329] Referring to embodiment 1920 of FIG. 19, it is assumed that modules 17 to 24 are excluded.

[0330] The electronic device (100) can obtain structural information including the location of the changed display module. The electronic device (100) can obtain new structural information to replace existing structural information. The electronic device (100) can obtain new structural information by updating existing structural information. The structural information prior to the update can be described as first structural information, and the structural information after the update can be described as second structural information.

[0331] The electronic device (100) can obtain new upscaling ratio information based on the updated structural information.

[0332] The electronic device (100) can acquire a new target resolution based on the updated structural information. The new target resolution may be described as an updated target resolution. The target resolution prior to the update may be described as a first target resolution (e.g., 4:6), and the target resolution after the update may be described as a second target resolution (e.g., 4:4).

[0333] The electronic device (100) may record new upscaling ratio information as updated upscaling ratio information. Upscaling ratio information prior to the update may be recorded as first upscaling ratio information, and upscaling ratio information after the update may be recorded as second upscaling ratio information (4:4).
