According to one embodiment, the receiver may be implemented separately from the speaker or as part thereof. The audio module may convert sound into an electrical signal, or conversely, convert an electrical signal into sound. According to one embodiment, the audio module may acquire sound through an input module or output sound through an audio output module or an external electronic device (e.g., a speaker or headphones) connected directly or wirelessly to the electronic device (200).

[0065] According to one embodiment, the display (203) can visually provide information to an external (e.g., user) of the electronic device (200). The display (200) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling said device. According to one embodiment, the display (200) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of the force generated by said touch.

[0066] According to one embodiment, the communication module (205) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between an electronic device (200) and an external electronic device (e.g., a plurality of display devices (100) or a server), and the performance of communication through the established communication channel. The communication module (205) may include one or more communication processors that operate independently of the processor (201) (e.g., an application processor) and support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (205) may include a wireless communication module (e.g., a cellular communication module, a short-range communication module, or a GNSS (global navigation satellite system) communication module) or a wired communication module (e.g., a LAN (local area network) communication module, or a power line communication module). Among these communication modules, the corresponding communication modules can communicate with external electronic devices through a network (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct or IrDA (infrared data association), or a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a long-range communication network such as a computer network (e.g., LAN or WAN). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips).

[0067] FIG. 2 illustrates the configuration of an electronic device for controlling a multi-display including a 3D display device according to one embodiment of the present disclosure.

[0068] FIG. 3 is a flowchart illustrating a method for an electronic device to control a multi-display including a 3D display device according to one embodiment of the present disclosure.

[0069] Referring to FIG. 2, an electronic device (e.g., the electronic device (200) of FIG. 1) may include at least one module for supporting a display (e.g., a 3D display). The at least one module may include, for example, a display detection module (210), a screen status check module (220), a 3D function control module (230), a screen control module (240), and / or a 3D processing module (250). The at least one module may be implemented by a memory of the electronic device (200) (e.g., the memory (202) of FIG. 1) and / or at least one processor (e.g., the processor (201) of FIG. 1). For example, the at least one module consists of instructions stored in memory, and when the instructions are executed individually and / or collectively by at least one processor, they may cause the electronic device to perform at least one operation associated with the at least one module.

[0070] According to one embodiment, the display detection module (210) can identify at least one display device connected to the electronic device (200). According to one embodiment, the display detection module (210) can identify whether at least one display device connected to the electronic device (200) is a 3D display device (e.g., the 3D display device (100a) of FIG. 1) or a 2D display device (e.g., the display device (100b) of FIG. 1). For example, the display detection module (210) can distinguish whether the display device is a 3D display device or a 2D display device by using the device identifier (e.g., ID) of the display device based on the fact that the display device is connected to the electronic device (200). In this way, the display detection module (210) can detect whether a single 3D display device is connected to the electronic device (200), whether the 3D display device is connected together with a 2D display device, or whether the 3D display device is connected together with another 3D display device.

[0071] According to one embodiment, the screen status checking module (220) can check the screen status of the display device. For example, the screen status checking module (220) can check the video or content currently to be output or displayed on the display device (e.g., 3D display device) and, if necessary, support the 3D processing module (250) to perform processing (e.g., conversion) for displaying the 3D video. According to one embodiment, the screen status checking module (220) can identify the aspect ratio and / or multi-display arrangement status of the video or content and provide information on whether to move the execution screen (e.g., playback screen) of the video or content or to display the 3D video on the display device. The information may include, for example, information indicating whether the video or content can be displayed on a 3D display.

[0072] According to one embodiment, the 3D function control module (230) can control at least one function related to a 3D display. For example, if the 3D display device requires the display of a 3D image, the 3D function control module (230) can convert the configuration of the 3D display device (e.g., hardware configuration) to a configuration suitable for a 3D display. According to one embodiment, the 3D function control module (230) can run rendering software for a 3D display.

[0073] According to one embodiment, the screen control module (240) can control the screen of the display device. For example, when a 3D display device and a 2D display device are connected together, the screen control module (240) can control the display so that a 3D image is displayed only on the 3D display device based on the acquisition of a 3D display request.

[0074] According to one embodiment, the 3D processing module (250) can perform processing for 3D display (e.g., image processing, format conversion processing). For example, the 3D processing module (250) can acquire image data in a 3D format (e.g., side-by-side format). For example, the 3D processing module (250) can convert image data in a 2D format into image data in a 3D format. For example, the 3D processing module (250) can convert image data in a 3D format into image data in a 2D format.

[0075] Referring to FIG. 3, according to one embodiment, in operation 310, the electronic device (200) may obtain a request for a 3D display while a plurality of display devices are connected to the electronic device. In the present disclosure, a request for a 3D display may be abbreviated as a 3D display request.

[0076] According to one embodiment, the electronic device (200) can identify that a plurality of display devices are connected to the electronic device using a display detection module (210) and identify the type of the connected display device (e.g., a 3D display device or a 3D display device). According to one embodiment, the plurality of display devices may include at least one 3D display device that supports a 3D display (e.g., the 3D display device (100a) of FIG. 1). For example, the plurality of display devices may include a first 3D display device that supports a 3D display. According to one embodiment, the plurality of display devices may be configured as a multi-display. In the present disclosure, a multi-display environment composed of only a plurality of 2D display devices may be referred to as a first multi-display environment (or, 2D multi-display environment), a multi-display environment composed of one 3D display device and at least one 2D display device may be referred to as a second multi-display environment (or, 1st 3D multi-display environment), and a multi-display environment including a plurality of 3D displays may be referred to as a third multi-display environment (or, 2nd 3D multi-display environment).

[0077] According to one embodiment, a request for a 3D display may be obtained based on user input or based on the identification that a specified condition is satisfied. For example, an electronic device may identify that a request for a 3D display is obtained in response to receiving user input for the execution or activation of a 3D display (e.g., input pressing a specified physical button or a UI button included in the execution screen). The specified condition may be satisfied, for example, when an application requiring the activation of a 3D display (e.g., a 3D game application) is executed, but is not limited thereto.

[0078] According to one embodiment, in operation 320, the electronic device (200) may acquire first image data in a 3D format (e.g., side-by-side format) according to multi-display mode information based on the acquisition of a request for a 3D display. According to one embodiment, in operation 330, the electronic device (200) may transmit a first image signal containing the first image data in a 3D format to a first 3D display device. Operations 320 and 330 may be performed using a screen status check module (220), a 3D function control module (230), a screen control module (240), and / or a 3D processing module (250).

[0079] According to one embodiment, multi-display mode information may indicate a multi-display mode. The multi-display mode may be, for example, one of a display duplication mode or a display extension mode.

[0080] According to one embodiment, the display duplication mode may be a mode in which content (e.g., video) displayed on the screen of one display device (e.g., main display device) is duplicated and displayed on the screen of another display device configured as a multi-display. For example, in the display duplication mode, video of the same content may be displayed on multiple display devices configured as a multi-display. This display duplication mode has the advantage of being simpler to set up compared to the display extension mode and being able to display the same content (e.g., the same frame) through multiple screens. However, in the display duplication mode, the resolution of the other display devices may be affected by the resolution of the main display device.

[0081] According to one embodiment, the display expansion mode may be a mode in which the entirety of the screens of a plurality of display devices configured as a multi-display is recognized as one wide screen, and each screen of each display device is recognized as a part of one wide screen. In the display expansion mode, a portion of an image of the same content may be divided and displayed on the screens of each display device. For example, a portion of an image having a 32:9 aspect ratio, such as the left half and the right half of the image, may be displayed on the screens of each display device having a 16:9 aspect ratio. In the display expansion mode, execution screens of different content may be displayed on the screens of each display device. For example, a first execution screen of a first application (e.g., a document processing application) may be displayed on the screen of the first display device, and a second execution screen of a second application (e.g., an internet application) may be displayed on the screen of the second display device. In the display expansion mode, an execution screen displayed on the screen of one display device may be moved to the screen of another display device. For example, in the display expansion mode, an execution screen displayed on the screen of one display device may be moved to the screen of another display device according to user input (e.g., touch input or mouse input). This extended display mode is suitable for multitasking as it can provide users with an expanded workspace, and it has the advantage that settings for each display device (e.g., resolution settings) can be performed individually. However, the settings for extended display mode can be more complex compared to duplicate display mode.

[0082] According to one embodiment, a plurality of display devices may further include a 2D display device that supports a 2D display (e.g., the 2D display device (100b) of FIG. 1). For example, a plurality of display devices configured as a multi-display may include a first 3D display device and a 2D display device. Through this, a second multi-display environment may be provided. Various examples of display operations in the second multi-display environment are described below with reference to FIGS. 4 through 8b.

[0083] According to one embodiment, a plurality of display devices include a first 3D display device and a 2D display device, and when the multi-display mode is a display replication mode, the electronic device (200) may acquire image data including first image data in a 3D format and second image data in a 2D format, transmit a first image signal including first image data in a 3D format to the first 3D display device, and transmit a second image signal including second image data in a 2D format to the 2D display device. According to one embodiment, the first image data in a 3D format and the second image data in a 2D format may be image data for the same content (e.g., game image content). The first 3D display device may display a 3D image based on the first image data, and the 2D display device may display a 2D image based on the second image data. Thus, in a second multi-display environment, when the display replication mode is applied, a 3D image and a 2D image for the same content may be displayed simultaneously through each display device. Meanwhile, when the display duplication mode is applied in the first multi-display environment, completely identical 2D images of the same content are displayed simultaneously through each display device. In contrast, as described above, when the display duplication mode is applied in the second multi-display environment, 3D images and 2D images of the same content are displayed simultaneously through each display device, so the user can compare the playback of 3D images and 2D images of the same content (e.g., the same frame) in real time. This can provide the user with a new user experience. Through this, the user can clearly verify the 3D effect of the 3D display device.

[0084] According to one embodiment, a plurality of display devices include a first 3D display device and a 2D display device, and when the multi-display mode is a display extension mode, the electronic device (200) can obtain first image data in a 3D format by converting image data in a 2D format corresponding to a 2D image (or, first execution screen) into first image data in a 3D format based on identifying that at least a portion (e.g., more than half of the first execution screen) of a first execution screen including a 2D image of the 2D display device is moved to the first 3D display device. The movement of the first execution screen can be identified, for example, through a screen status check module (220). The electronic device (200) can transmit a first image signal including the first image data to the first 3D display device. The first 3D display device can display a 3D image based on the first image data. For example, the first 3D display device can display a second execution screen containing a 3D image based on the first image data on the screen (e.g., full screen) of the first 3D display device. In this way, in the second multi-display environment, when a display expansion mode is applied and at least a portion of the first execution screen containing a 2D image that was displayed on a 2D display device is moved to a 3D display device, the second execution screen containing a 3D image converted from a 2D image can be displayed on the full screen of the 3D display device. Meanwhile, in the first multi-display environment, when a display expansion mode is applied and at least a portion of the first execution screen containing a 2D image that was displayed on one 2D display device is moved to another 2D display device, the same 2D image is simply moved to the other 2D display device and displayed.In contrast, as described above, in a second multi-display environment, when a display extension mode is applied and at least a portion of an execution screen containing a 2D image displayed on a 2D display device is moved to a 3D display device, the 2D image can be naturally converted into a 3D image as the execution screen moves and provided to the user through the entire screen of the 3D display device. This can provide a new user experience to the user. Through this, the user can naturally convert between the 2D image and the 3D image as the execution screen moves between the 2D display device and the 3D display device.

[0085] According to one embodiment, a 3D display device (e.g., a first 3D display device and / or a second display device) may be a display device that supports both 3D display and 2D display. In this case, the 3D display device may operate in a 2D display mode or a 3D display mode depending on display mode information. According to one embodiment, the display mode information may indicate a display mode, and the display mode may be either a 2D display mode or a 3D display mode. Such display mode information may be used to switch the display mode in the 3D display device.

[0086] According to one embodiment, display mode information may be set by an electronic device (200). For example, the electronic device (200) may set the display mode information to a 3D display mode based on the acquisition of a 3D display request (e.g., at the time when a 3D display request is acquired). According to one embodiment, the electronic device (200) may transmit the set display mode information to a 3D display device (e.g., a first 3D display device and / or a second display device). While the 3D display device is operating in a 2D display mode, the display mode may be switched from a 2D display mode to a 3D display mode based on identifying that the display mode information indicating that the display mode is a 3D display mode is received from the electronic device (200). In this manner, the display mode of the 3D display device may be controlled by the electronic device (200).

[0087] According to one embodiment, display mode information may be included in a first image signal containing first image data in a 3D format. In this case, the first 3D display device may set the display mode to a 3D display mode based on the display mode information included in the first image signal and display a 3D image based on the first image data included in the first image signal. Through this method, communication resources between the electronic device and the 3D display device can be utilized efficiently compared to when the display mode information is transmitted separately from the image data, and delays due to display mode switching can be reduced.

[0088] According to one embodiment, a plurality of display devices may further include a second 3D display device that supports a 3D display (e.g., the 3D display device (100a) of FIG. 1). For example, a plurality of display devices configured as a multi-display may include a first 3D display device and a second 3D display device. Through this, a third multi-display environment may be provided. Various examples of display operations in the third multi-display environment are described below with reference to FIGS. 9 through 12b.

[0089] According to one embodiment, a plurality of display devices include a first 3D display device and a second 3D display device, and when the multi-display mode is a display extension mode (or a display duplication mode), the electronic device (200) can acquire image data in a 3D format (e.g., first image data and / or second image data) based on first aspect ratio information regarding the aspect ratio of an image (e.g., 2D image) and second aspect ratio information regarding the aspect ratio of at least one 3D display device (e.g., first 3D display device and / or second 3D display device) to be displayed.

[0090] According to one embodiment, in a third multi-display environment, if the aspect ratio of the image (e.g., 16:9) is the same as the aspect ratio of the 3D display device (e.g., 16:9) and the multi-display mode is a display extension mode (or a display duplication mode), the electronic device (200) can acquire image data in a 3D format such that a 3D image converted from a 2D image is displayed on at least one of the first 3D display device or the second 3D display device (e.g., one full screen). If the multi-display mode is a display extension mode, the electronic device (200) can transmit the image data to either the first 3D display device or the second 3D display device. If the multi-display mode is a display duplication mode, the electronic device (200) can transmit the same image data to both the first 3D display device and the second 3D display device. In this way, when the aspect ratio of the 2D image and the aspect ratio of the 3D display device are the same in a third multi-display environment, the electronic device (200) can change only the format of the image from a 2D format to a 3D format and transmit it to the 3D display device without adjusting the aspect ratio of the image. The 3D display device that receives the image data in the 3D format can display the 3D image on the entire screen based on the image data. Since the 3D image displayed in this way is an image converted from a 2D image to a 3D image without adjusting the aspect ratio of the image, the quality of the image may not degrade. Through this, the electronic device (200) can naturally convert and provide the 2D image into a 3D image without degrading the quality of the image. According to one embodiment, when the multi-display mode is a display extension mode, the execution screen of the 3D image displayed on one 3D display device can be moved to another 3D display device.Through this, 3D images can be displayed on the 3D display device desired by the user. According to one embodiment, when the multi-display mode is a display duplication mode, the execution screen of the same 3D image can be displayed simultaneously on each 3D display device. Through this, the user can compare the 3D performance of each 3D display device in real time.

[0091] According to one embodiment, in a third multi-display environment, when the aspect ratio of the image (e.g., 32:9) is greater than the aspect ratio of the 3D display device (e.g., 16:9) and the multi-display mode is a display extension mode, the electronic device (200) can acquire image data in a 3D format that causes the 3D image to be displayed on the first 3D display device and the second 3D display device. For example, the electronic device can acquire image data in a 3D format that includes first part image data in a 3D format corresponding to a first part of the image (e.g., the left half of the 2D image) and second part image data in a 3D format corresponding to a second part of the image (e.g., the right half of the 2D image). According to one embodiment, the first part image data can be used to display a first 3D image corresponding to the first part of the image on the first 3D display device, and the second part image data can be used to display a second 3D image corresponding to the second part of the image on the second 3D display device. The electronic device can transmit a first image signal containing first partial image data to a first 3D display device and transmit a second image signal containing second partial image data to a second 3D display device. In this way, when the aspect ratio of a 2D image in a third multi-display environment is greater than the aspect ratio of a 3D display device, the electronic device (200) can process the 3D image converted from the 2D image into multiple partial image data in a 3D format so that the 3D image is displayed on multiple 3D display devices, and transmit each partial image data to each 3D display device. Since the 3D image displayed in this way is an image converted from a 2D image to a 3D image without adjusting the aspect ratio of the image, no degradation of image quality occurs.In addition, since the 3D image is displayed through multiple 3D display devices, it can provide a better 3D effect compared to a second multi-display environment where the 3D image is displayed through a single 3D display device.

[0092] According to one embodiment, in a third multi-display environment, if the aspect ratio of the image (e.g., 16:9) is smaller than the aspect ratio of the 3D display device (e.g., 32:9) and the multi-display mode is a display extension mode (or a display duplication mode), the electronic device (200) can acquire image data in a 3D format such that a 3D image converted from a 2D image is displayed on at least one of the first 3D display device or the second 3D display device (e.g., at least one full screen or a partial screen). If the multi-display mode is a display extension mode, the electronic device (200) can transmit the image data to either the first 3D display device or the second 3D display device. If the multi-display mode is a display duplication mode, the electronic device (200) can transmit the same image data to both the first 3D display device and the second 3D display device. Thus, when the aspect ratio of the video is smaller than the aspect ratio of the display, the electronic device (200) can adjust the aspect ratio of the video and transmit it to the 3D display device. The 3D display device that receives the video data in 3D format can display the 3D video on the entire screen based on the video data. Since the 3D video displayed in this way is a video in which the aspect ratio of the video has been adjusted (e.g., adjusted from 16:9 to 32:9), a degradation in the quality of the video may occur. According to one embodiment, the electronic device (200) can adjust the aspect ratio of the video using a learned AI model (e.g., a generative AI model). Through this, the degradation in quality caused by the adjustment of the aspect ratio of the video can be reduced.

Additionally, in the embodiments of FIGS. 4 to 8b, it is assumed that an image of content (e.g., game content) is displayed on at least one display device.

[0099] Referring to FIG. 4, according to one embodiment, in operation 410, the electronic device (200) identifies a 3D display device (100a) and at least one 2D display device (100b) and can set the 3D display device (100a) and at least one 2D display device (100b) as a multi-display. Operation 410 can be performed, for example, using the display detection module (210) of FIG. 2.

[0100] According to one embodiment, the electronic device (200) can set the 3D display device (100a) and at least one 2D display device (100b) as a multi-display in response to identifying that the 3D display device (100a) and at least one 2D display device (100b) are connected to the electronic device (200) via a wired connection (e.g., wired connection via HDMI or USB-C type cable) or a wireless connection (e.g., wireless connection via Wi-Fi or Wi-Fi Direct).

[0101] According to one embodiment, an electronic device (200) may set multi-display setting information for setting up a multi-display. The multi-display setting information may include, for example, multi-display environment information, multi-display mode information, multi-display arrangement information, and / or multi-display resolution information. The multi-display environment information may indicate a multi-display environment. As described above, the multi-display environment may be one of a first multi-display environment, a second multi-display environment, or a third multi-display environment. As described above, the multi-display mode information may indicate a multi-display mode. The multi-display arrangement information may include arrangement information for a plurality of display devices set up as a multi-display. For example, the multi-display arrangement information may include information regarding the relative position of a 3D display device (100a) to at least one 2D display device (100b) set up as a multi-display. The multi-display resolution information may include information regarding the resolution of each of the plurality of display devices set up as a multi-display. The resolutions of the plurality of display devices set up as a multi-display may be the same or different from each other.

[0102] According to one embodiment, in operation 420, the electronic device (200) can obtain a 3D display request in a second multi-display environment. Operation 420 may include, for example, operation 310 of FIG. 3.

[0103] According to one embodiment, in operation 430, the electronic device (200) may acquire image data based on a 3D display request. Operation 430 may include, for example, operation 320 of FIG. 3. The operation of acquiring image data may include, for example, an operation of converting an image in a 2D format into an image in a 3D format.

[0104] According to one embodiment, an electronic device (200) may acquire image data based on at least one setting information. The at least one setting information may include, for example, multi-display setting information, content information, and / or display mode information, but is not limited thereto. The content information may include information about content to be displayed on at least one of a plurality of display devices set as multi-displays (e.g., a 3D display device). The content information may include, for example, information about the type of content (e.g., 2D, 3D content) and / or information about the aspect ratio of the image corresponding to the content, but is not limited thereto. The at least one setting information may be acquired and / or used, for example, in a display detection module (210), a screen status check module (220), a 3D function control module (230), and / or a screen control module (240).

[0105] According to one embodiment, the image data may include a first image data in a 3D format and / or a second image data in a 2D format.

[0106] According to one embodiment, when the multi-display mode in a second multi-display environment is a display replication mode, the electronic device (200) can acquire image data including first image data in a 3D format and second image data in a 2D format. According to one embodiment, the first image data in a 3D format and the second image data in a 2D format may be image data for the same content (e.g., game video content). According to one embodiment, the operation of acquiring the first image data in a 3D format may include, for example, an operation of converting image data in a 2D format into image data in a 3D format.

[0107] According to one embodiment, when the multi-display mode in the second multi-display environment is a display extension mode, the electronic device (200) can obtain the first image data in 3D format by converting the image data in 2D format into the first image data in 3D format.

[0108] According to one embodiment, when the multi-display mode in the second multi-display environment is a display extension mode, the electronic device (200) can obtain first image data in a 3D format by converting image data in a 2D format corresponding to the 2D image (or the first execution screen) into first image data in a 3D format, based on the identification that at least a portion (e.g., more than half of the first execution screen) of a first execution screen including a 2D image of a 2D display device is moved to a first 3D display device. The movement of the first execution screen can be identified, for example, through a screen status check module (220).

[0109] According to one embodiment, after a 3D display request is obtained, the electronic device (200) may visually or audibly provide guide information (e.g., guide information (811) of FIG. 8) that guides changing the placement of the 3D display device without converting the image in 2D format into an image in 3D format, based on identifying, based on multi-display placement information, that the 3D display device is not placed at a designated location (e.g., center) in the configuration of the entire display device. This is because if the 3D display device is not placed in the center but is placed on the side in the configuration of the entire display device, displaying the 3D image may be unnecessary or inefficient.

[0110] According to one embodiment, in operation 440, the electronic device (200) may transmit a first image signal including first image data in a 3D format to a 3D display device (100a). Operation 440 may include, for example, operation 330 of FIG. 3. According to one embodiment, in operation 460, the 3D display device (100a) may display a 3D image based on the first image data. For example, the 3D display device (100a) may display an execution screen (or playback screen) including a 3D image based on the first image data.

[0111] According to one embodiment, in operation 450, the electronic device (200) may transmit a second image signal including second image data in a 2D format to a 2D display device. According to one embodiment, in operation 470, the 2D display device (100b) may display a 2D image based on the second image data. For example, the 2D display device (100b) may display an execution screen (or playback screen) including a 2D image based on the second image data. According to an embodiment, operations 450 and 470 may be omitted.

[0112] According to one embodiment, as illustrated in FIG. 5a and 5b, when the multi-display mode is a display duplication mode, a 3D display device (100a) and a 2D display device (100b) can simultaneously display a first execution screen (501a, 501b) and a second execution screen (502a, 502b) containing duplicated 2D images of the same content. For example, as illustrated in FIG. 5b, the first execution screen (501b) and the second execution screen (502b) may contain completely identical 2D images at point A (e.g., scene A or frame A) of the same content (e.g., game content). After a 3D display request (510) is obtained, the 3D display device (100a) may display a third execution screen (503a, 503b) containing a 3D image (e.g., a 3D image in a side-by-side format), and the 2D display device (100b) may display a fourth execution screen (504a, 504b) containing a 2D image. For example, as shown in FIG. 5b, the third execution screen (503b) and the fourth execution screen (504b) may each include a 3D image and a 2D image at point B (e.g., scene B or frame B) of the same content (e.g., game content). Thus, in a second multi-display environment, when a display duplication mode is applied, a 3D image and a 2D image of the same content (e.g., video content) may be displayed simultaneously through each display device. In this case, the user can compare the playback of the 3D image and the 2D image of the same content in real time. This can provide users with a new user experience. Through this, users can clearly see the 3D effects of the 3D display device.

[0113] According to one embodiment, as illustrated in FIG. 6a and 6b, when the multi-display mode is a display extension mode, a 3D display device (100a) and a 2D display device (100b) can simultaneously display a first execution screen (601a, 601b) and a second execution screen (602a, 602b) containing different 2D images (e.g., different parts of 2D images of the same content). For example, as illustrated in FIG. 6b, the first execution screen (601b) and the second execution screen (602b) may each include a 2D image corresponding to a first image part of point A (e.g., scene A or frame A) of the same content (e.g., game content) and a 2D image corresponding to a second image part different from the first image part. After a 3D display request (610) is obtained, the 3D display device (100a) may display a third execution screen (603a, 603b) containing a 3D image (e.g., a 3D image in a side-by-side format), and the 2D display device (100b) may display a fourth execution screen (604a, 604b) containing a 2D image. For example, as shown in FIG. 6b, the third execution screen (603b) and the fourth execution screen (604b) may each include a 3D image corresponding to a third image portion of point B (e.g., scene B or frame B) of the same content (e.g., game content) and a 2D image corresponding to a fourth image portion different from the third image portion. In this way, when a display extension mode is applied in a second multi-display environment, the 2D image can be naturally converted into a 3D image and displayed on the screen of the 3D display device. This can provide a new user experience to the user. In this way, the user can naturally convert a 2D image into a 3D image by providing a 3D display request to the electronic device (200).

[0114] According to one embodiment, as illustrated in FIG. 7a and 7b, when the multi-display mode is a display extension mode, the 2D display device (100b) can display a first execution screen (701a, 701b) containing a 2D image. For example, as illustrated in FIG. 7b, the first execution screen (701b) may include a 2D image of point A (e.g., scene A or frame A) of video content (e.g., game content). After a 3D display request (710) is obtained, it may be identified (711) that at least a portion (701a-1, 701b-1) of the first execution screen (701a, 701b) is moved to the screen of the 3D display device (100a). After it is identified (720) that the movement of the first execution screen (701a, 701b) satisfies a specified condition, the 3D display device (100a) can display a second execution screen (702a, 702b) containing a 3D image converted from a 2D image (e.g., a 3D image in a side-by-side format) on the entire screen of the 3D display device (100a). According to one embodiment, the specified condition may be satisfied, for example, when the size of the first part (701a-1, 701b-1) of the first execution screen (701a, 701b) moved to the screen of the 3D display device (100a) is larger than half the size of the entire screen of the 3D display device (100a), or when the size of the second part (701a-1, 701b-1) of the first execution screen (701a, 701b) remaining on the screen of the 2D display device (100b) is larger than. As illustrated in FIG. 7b, the second execution screen (702b) may include a 3D image of point B (e.g., scene B or frame B) of the video content (e.g., game content).In this way, in a second multi-display environment, when a display extension mode is applied and at least a portion of a first execution screen containing a 2D image that was displayed on a 2D display device is moved to a 3D display device, a second execution screen containing a 3D image converted from a 2D image can be displayed on the entire screen of the 3D display device. Through this method, as the execution screen moves, the 2D image can be naturally converted into a 3D image and provided to the user through the entire screen of the 3D display device. This can provide a new user experience to the user. Through this, the user can naturally convert between the 2D image and the 3D image as the execution screen moves between the 2D display device and the 3D display device.

[0115] According to one embodiment, as illustrated in FIG. 8a and 8b, when the multi-display mode is a display extension mode, the 3D display device (100a), the first 2D display device (100b-1), and the second 2D display device (100b-1) can each display different execution screens. For example, as illustrated in FIG. 8b, the 3D display device (100a), the first 2D display device (100b-1), and the second 2D display device (100b-1) can each display different execution screens containing different 2D image portions of point A (e.g., scene A or frame A) of the same content (e.g., game content). After a 3D display request (810) is obtained, at least one display device (e.g., a display device positioned in the center of the entire display device configuration) can display guide information (811) that guides a change in the positioning of the 3D display device (100a). According to one embodiment, after a 3D display request (810) is obtained, if the electronic device (200) identifies, based on multi-display placement information, that the 3D display device (100a) is not placed in the center of the configuration of the entire display device, it may provide guide information (811) visually or audibly without immediately converting the 2D image into a 3D image. This is because if the 3D display device (100a) is not placed in the center of the configuration of the entire display device but is placed on the side, displaying the 3D image may be unnecessary or inefficient.After the guide information (811) is provided, if it is identified (820) that the 3D display device (100a) is positioned in the center of the entire display device configuration according to the change in the placement (821) of the display device, the 3D display device (100a) can display an execution screen containing a 3D image converted from a 2D image (e.g., a 3D image in a side-by-side format) on the screen (e.g., the entire screen) of the 3D display device (100a). For example, as shown in FIG. 8b, the 3D image may include a 3D image at point B (e.g., scene B or frame B) of the image content (e.g., game content). Thus, in the second multi-display environment, even if a display extension mode is applied and a 3D display request is obtained, if displaying the 3D image is unnecessary or inefficient, the 3D image is not displayed immediately, and guide information such as a guide to change the placement of the 3D display device can be provided to the user. Through this method, 3D video can be provided only when the display of 3D video is necessary or when the situation changes to an efficient one. This allows for the efficient provision of 3D video and prevents the waste of unnecessary resources associated with the provision of 3D video.

[0116] FIG. 9 is a signal flowchart illustrating a procedure for an electronic device to control a display device in a third multi-display environment according to one embodiment of the present disclosure.

[0117] FIGS. 10a and 10b are drawings illustrating a screen of a display device in which the aspect ratio of an image is the same as the aspect ratio of a display when a display extension mode is applied in a third multi-display environment according to one embodiment of the present disclosure.

[0118] FIGS. 11a and 11b are drawings illustrating a screen of a display device in which the aspect ratio of an image is greater than the aspect ratio of a display when a display extension mode is applied in a third multi-display environment according to one embodiment of the present disclosure.

[0119] FIGS. 12a and 12b are drawings illustrating a screen of a display device in which the aspect ratio of an image is smaller than the aspect ratio of a display when a display extension mode is applied in a third multi-display environment according to one embodiment of the present disclosure.

[0120] According to one embodiment, in the embodiment of FIGS. 9 to 12b, it is assumed that the multi-display environment is a third multi-display environment comprising a plurality of 3D display devices. Additionally, in the embodiment of FIGS. 9 to 12b, it is assumed that an image of content (e.g., game content) is displayed on at least one display device.

[0121] Referring to FIG. 9, according to one embodiment, in operation 910, the electronic device (200) identifies a first 3D display device (100a-1) and a second 3D display device (100a-2), and can set the first 3D display device (100a-1) and the second 3D display device (100a-2) as a multi-display.

[0122] According to one embodiment, the electronic device (200) can set the first 3D display device (100a-1) and the second 3D display device (100a-2) as a multi-display in response to identifying that the first 3D display device (100a-1) and the second 3D display device (100a-2) are connected to the electronic device (200) via a wired connection (e.g., wired connection via HDMI or USB-C type cable) or a wireless connection (e.g., wireless connection via Wi-Fi or Wi-Fi Direct).

[0123] According to one embodiment, the electronic device (200) can set multi-display setting information for setting up a multi-display. The multi-display setting information may include, for example, multi-display environment information, multi-display mode information, multi-display placement information, and / or multi-display resolution information. For a description of the multi-display setting information, refer to the description of the multi-display setting information in FIG. 4.

[0124] According to one embodiment, in operation 920, the electronic device (200) can obtain a 3D display request in a third multi-display environment. Operation 920 may include, for example, operation 310 of FIG. 3.

[0125] According to one embodiment, in operation 930, the electronic device (200) may acquire image data based on a 3D display request. Operation 930 may include, for example, operation 320 of FIG. 3. The operation of acquiring image data may include, for example, an operation of converting an image in a 2D format into an image in a 3D format.

[0126] According to one embodiment, an electronic device (200) can acquire image data based on at least one setting information. The at least one setting information may include, for example, multi-display setting information, content information, and / or display mode information, but is not limited thereto. For a description of the at least one setting information, refer to the description of the at least one setting information in FIG. 4.

[0127] According to one embodiment, the image data may include a first image data in a 3D format and / or a second image data in a 3D format.

[0128] According to one embodiment, in a third multi-display environment, if the aspect ratio of the image (e.g., 16:9) is the same as the aspect ratio of the 3D display device (e.g., 16:9) and the multi-display mode is a display extension mode (or a display duplication mode), the electronic device (200) can acquire image data in a 3D format such that a 3D image converted from a 2D image is displayed on at least one of the first 3D display device or the second 3D display device (e.g., one full screen). If the multi-display mode is a display extension mode, the electronic device (200) can transmit the image data to either the first 3D display device or the second 3D display device. If the multi-display mode is a display duplication mode, the electronic device (200) can transmit the same image data to both the first 3D display device and the second 3D display device.

[0129] According to one embodiment, in a third multi-display environment, when the aspect ratio of the image (e.g., 32 to 9) is greater than the aspect ratio of the 3D display device (e.g., 16 to 9) and the multi-display mode is a display extension mode, the electronic device (200) can acquire image data in a 3D format that causes the 3D image to be displayed on the first 3D display device and the second 3D display device. For example, the electronic device can acquire image data in a 3D format that includes first part image data in a 3D format corresponding to a first part of the image (e.g., the left half of the 2D image) and second part image data in a 3D format corresponding to a second part of the image (e.g., the right half of the 2D image). The electronic device can transmit a first image signal containing the first part image data to the first 3D display device and transmit a second image signal containing the second part image data to the second 3D display device.

[0130] According to one embodiment, in a third multi-display environment, if the aspect ratio of the image (e.g., 16:9) is smaller than the aspect ratio of the 3D display device (e.g., 32:9) and the multi-display mode is a display extension mode (or a display duplication mode), the electronic device (200) can acquire image data in a 3D format such that a 3D image converted from a 2D image is displayed on at least one of the first 3D display device or the second 3D display device (e.g., at least one full screen or a partial screen). If the multi-display mode is a display extension mode, the electronic device (200) can transmit the image data to either the first 3D display device or the second 3D display device. If the multi-display mode is a display duplication mode, the electronic device (200) can transmit the same image data to both the first 3D display device and the second 3D display device.

[0131] According to one embodiment, in operation 940, the electronic device (200) may transmit a first image signal containing first image data in a 3D format to a first 3D display device (100a-1). Operation 940 may include, for example, operation 330 of FIG. 3. According to one embodiment, in operation 960, the first 3D display device (100a-1) may display a first 3D image based on the first image data. For example, the first 3D display device (100a-1) may display an execution screen (or playback screen) containing a 3D image based on the first image data. According to an embodiment, operations 940 and 960 may be omitted.

[0132] According to one embodiment, in operation 950, the electronic device (200) may transmit a second image signal containing second image data in a 3D format to a second 3D display device (100a-2). According to one embodiment, in operation 970, the second 3D display device (100a-2) may display a second 3D image based on the second image data. For example, the second 3D display device (100a-2) may display an execution screen (or playback screen) containing the second 3D image based on the second image data. According to an embodiment, operations 950 and 970 may be omitted.

[0133] According to one embodiment, as illustrated in FIG. 10a and 10b, a 3D display request (1010, 1020) may be identified in a third multi-display environment comprising a first 3D display device (100a-1) and a second 3D display device (100a-2). In this case, if the aspect ratio of the image (e.g., 16 to 9) is the same as the aspect ratio of the 3D display device (e.g., 16 to 9) and the multi-display mode is a display extension mode, the first 3D display device (100a-1) or the second 3D display device (100a-2) may display an execution screen (1001a, 1002a) containing a 3D image (e.g., a 3D image in a side-by-side format). For example, as illustrated in FIG. 10b, a first execution screen (1001b) of content (e.g., game content) may be displayed on a first 3D display device (100a-1), or a second execution screen (1002b) may be displayed on a second 3D display device (100a-2). In this way, when the aspect ratio of the 2D image and the aspect ratio of the 3D display device are the same, the image format may be changed from a 2D format to a 3D format and transmitted to the 3D display device without adjusting the aspect ratio of the image. The 3D display device that receives the image data in a 3D format may display the 3D image on the entire screen based on the image data. Since the 3D image displayed in this way is an image converted from a 2D image to a 3D image without adjusting the aspect ratio of the image, there may be no degradation in image quality. Through this, the 2D image can be naturally converted into a 3D image and provided without degradation in image quality.

[0134] According to one embodiment, as illustrated in FIG. 11a and 11b, when a display extension mode is applied in a third multi-display environment, the first 3D display device (100a-1) and the second 3D display device (100a-2) can respectively display a first execution screen (1101a, 1101b) and a second execution screen (1102a, 1102b). After a 3D display request (1110) is identified, if the aspect ratio of the image (e.g., 32 to 9) is greater than the aspect ratio of the 3D display device (e.g., 16 to 9), the first 3D display device (100a-1) may display a third execution screen (1103a, 1103b) containing a first 3D image portion (e.g., a first 3D image portion in a side-by-side format) corresponding to a first portion of the image, and the second 3D display device (100a-2) may display a fourth execution screen (1104a, 1104a) containing a second 3D image portion (e.g., a second 3D image portion in a side-by-side format) corresponding to a second portion different from the first portion of the image. For example, as illustrated in FIG. 11b, a third execution screen (1103b) including a first 3D image portion corresponding to a first part of the image of content (e.g., game content) may be displayed on a first 3D display device (100a-1), and a fourth execution screen (1104b) including a second 3D image portion corresponding to a second part of the image may be displayed on a second 3D display device (100a-2). Since the 3D image displayed in this way is an image converted from a 2D image to a 3D image without adjusting the aspect ratio of the image, no degradation of image quality occurs. In addition, since the 3D image is displayed through multiple 3D display devices, a better 3D effect can be provided compared to a second multi-display environment where the 3D image is displayed through a single 3D display device.

[0135] According to one embodiment, as illustrated in FIG. 12a and 12b, when a display extension mode is applied in a third multi-display environment, the first 3D display device (100a-1) or the second 3D display device (100a-2) may display a first execution screen (1201a, 1201b) containing an image smaller than the aspect ratio of the display. For example, as illustrated in FIG. 12b, the first 3D display device (100a-1) may display a first execution screen (1201b) containing an image (e.g., an image of game content) that is smaller than the aspect ratio of the first 3D display device (100a-1). After a 3D display request (1210) is identified, if the aspect ratio of the image (e.g., 16:9) is greater than the aspect ratio of the 3D display device (e.g., 32:9), the first 3D display device (100a-1) or the second 3D display device (100a-2) may display a second execution screen (1202a, 1202b) containing a 3D image with an aspect ratio adjusted (e.g., a 3D image in a side-by-side format). For example, as illustrated in FIG. 12b, the first 3D display device (100a-1) may display the second execution screen (1202b) containing a 3D image with an aspect ratio adjusted (e.g., adjusted from 16:9 to 32:9) on the entire screen of the first 3D display device (100-1). Since the 3D video displayed in this way has its aspect ratio adjusted, some degradation in video quality may occur, but because it is provided through the full screen, it can have a better 3D effect compared to being provided on only a part of the screen.

[0136] According to one embodiment, an electronic device identifies at least one 3D display device configured as a multi-display and can control the 3D display of the 3D display device. According to one embodiment, the electronic device can control the 3D display of the 3D display device based on at least one setting information (e.g., multi-display setting information) in a multi-display environment including a 3D display device. Through this, the usability of the 3D display device in a multi-display environment can be increased.

[0137] According to one embodiment, the electronic device may include a memory comprising at least one storage medium for storing instructions; and at least one processor comprising a processing circuit. The at least one processor acquires a request for a three-dimensional (3D) display while a plurality of display devices are connected to the electronic device, wherein the plurality of display devices include a first 3D display device that supports the 3D display, and based on the acquisition of the request for the 3D display, acquires first image data in a 3D format according to multi-display mode information indicating a multi-display mode, and transmits a first image signal including the first image data in a 3D format to the first 3D display device, wherein the multi-display mode may be one of a display duplication mode or a display extension mode.

[0138] According to one embodiment, the plurality of display devices further include a 2D display device that supports a 2D display, the multi-display mode is the display replication mode, and the at least one processor transmits a second image signal including second image data in the 2D format to the 2D display device, and the first image data and the second image data may be image data for the same content.

[0139] According to one embodiment, the plurality of display devices further include a 2D display device that supports a 2D display, the multi-display mode is the display extension mode, and the at least one processor can obtain the first image data in the 3D format by converting image data in the 2D format corresponding to the execution screen into the first image data in the 3D format based on identifying that at least a portion of the execution screen of the 2D display device is moved to the first 3D display device.

[0140] According to one embodiment, an execution screen corresponding to the first image data of the 3D format can be displayed on the entire screen of the first 3D display device.

[0141] According to one embodiment, the first 3D display device is a display device that supports both the 3D display and the 2D display, and the at least one processor can transmit display mode information to the first 3D display device for switching the display mode of the first 3D display device from a 2D display mode to a 3D display mode.

[0142] According to one embodiment, the display mode information may be included in the first image signal.

[0143] According to one embodiment, the plurality of display devices further include a second 3D display device that supports a 3D display, the multi-display mode is the display extension mode, and the at least one processor can acquire first image data of the 3D format based on first aspect ratio information for an aspect ratio of an image and second aspect ratio information for an aspect ratio of a display to which at least a portion of the image is to be displayed.

[0144] According to one embodiment, the at least one processor can be configured such that when the aspect ratio of the image is the same as the aspect ratio of the display, the first image data in the 3D format is displayed on either the first 3D display device or the second 3D display device.

[0145] According to one embodiment, the at least one processor can acquire: when the aspect ratio of the image is greater than the aspect ratio of the display, a first part image data of the 3D format corresponding to a first part of the image and a second part image data of the 3D format corresponding to a second part of the image.

[0146] According to one embodiment, the first partial image data may be used to display a first 3D image corresponding to a first part of the image on a first 3D display device, and the second partial image data may be used to display a second 3D image corresponding to a second part of the image.

[0147] According to one embodiment, a display device may include a display; a memory including at least one storage medium for storing instructions; and at least one processor including a processing circuit.
