[0034] FIG. 1 is a drawing showing a display device according to one embodiment.

[0035] Referring to FIG. 1, a display device (100) according to one embodiment may be a TV, but this is only one embodiment, and may be implemented in various forms including a display. For example, the display device (100) may be implemented in various forms such as a mobile phone, a tablet PC, a digital camera, a camcorder, a laptop computer, a desktop, an e-book reader, a digital broadcasting terminal, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia Player), a navigation device, an MP3 player, a wearable device, etc.

[0036] Additionally, the display device (100) may be a fixed electronic device placed in a fixed location or a portable electronic device having a portable form, and may be a digital broadcast receiver capable of receiving digital broadcasts. In particular, the embodiments can be easily implemented in a display device with a large display, such as a TV, but are not limited thereto.

[0037] The display device (100) may be implemented as a flat display device, a curved display device having a screen with a curvature, or a flexible display device whose curvature can be adjusted. The output resolution of the display device (100) may include, for example, HD (High Definition), Full HD, Ultra HD, or a resolution clearer than Ultra HD.

[0038] According to one embodiment, the display device (100) can run different types of operating systems (OS). The OS may refer to system software that manages the hardware and software resources of the display device (100) and provides common services for programs (processes). The OS acts as an interface between the user and the hardware and enables various application programs to efficiently use the hardware.

[0039] A display device (100) according to one embodiment can drive a first OS and a second OS of different types. For example, the display device (100) can drive only the first OS, simultaneously drive the first OS and the second OS, or drive only the second OS.

[0040] The first OS and the second OS according to one embodiment may include, but are not limited to, Tizen, Android TV, webOS, Roku TV, Fire TV, Apple tvOS, My Home screen, VIDAA, SmartCast, NetRange, etc.

[0041] According to one embodiment, the display device (100) can update the OS installed (or stored) in the display device (100). The OS update may refer to a process of upgrading the OS used in the display device (100) to the latest version. Through the OS update, the display device (100) can strengthen security, add new functions, and improve the performance of the display device (100). In addition, through the OS update, the display device (100) can improve stability by fixing bugs in the system, and ensure compatibility with the latest applications and hardware.

[0042] When the memory of a display device (100) equipped with an OS according to one embodiment is configured as a single partition, the user cannot use the display device (100) while performing an OS update. The display device (100) may display a screen (10) indicating that the OS is being updated, as illustrated in FIG. 1, while the OS is being updated.

[0043] Meanwhile, if the memory of a display device (100) equipped with an OS is configured as a dual partition including a first partition and a second partition, the display device (100) can perform an OS update using the second partition while running the OS using the first partition. In this case, the user can use the display device (100) even while performing an OS update.

[0044] However, as described above, when configuring the memory as a dual partition, the second partition of the memory is not used and is wasted while the OS is not updated, which increases the manufacturing cost of the display device (100).

[0045] Additionally, when including different OSs, configuring the memory for each OS as a dual partition will further increase the wasted space and manufacturing cost while the OS is not being updated.

[0046] A display device (100) according to one embodiment can update a second OS while only the first OS is running, and can update the first OS while only the second OS is running, without configuring the memory in which each OS is installed as a dual partition.

[0047] For example, when an update of the second OS is required, the display device (100) can drive only the first OS, display the home screen (20) for the first OS (operating in the foreground), as shown in FIG. 1, and update the second OS in the background.

[0048] Additionally, when an update of the first OS is required, the display device (100) can drive only the second OS, display the home screen for the second OS, and update the first OS in the background.

[0049] A display device (100) according to one embodiment can prevent a user's viewing experience from being interrupted by not configuring the memory in which each OS is installed as a dual partition, but updating another OS in the background while one OS is running.

[0050] Referring to the drawings below, the operations of the display device (100) according to one embodiment driving and updating heterogeneous OSs will be described in detail.

[0051] FIG. 2 is a diagram showing the configuration of a memory of a display device according to one embodiment.

[0052] Referring to FIG. 2, the memory (130) of the display device (100) according to one embodiment may include volatile / non-volatile memory. For example, the memory (130) may store commands or data related to at least one other component of the display device (100). The memory (130) according to one embodiment may store software and / or programs. For example, the memory (130) may include a first kernel (211), a second kernel (212), a HAL adapter (220) for a first OS, a first hardware virtualization layer (HAL: Hardware Abstraction Layer) (231), a second HAL (232), a first OS (241), a second OS (242), and a data storage unit (250).

[0053] According to one embodiment, the first kernel (211) may include software that is loaded into memory (RAM) and executed when the first OS (241) is booted. When the first kernel is loaded, the system hardware is initialized, and other components of the first OS (241) are loaded to enable use of the system.

[0054] A second kernel (212) according to one embodiment may include software that is loaded into memory and executed when the second OS (242) is booted. When the second kernel (212) is loaded, the system hardware is initialized, and other components of the second OS (242) are loaded, making the system usable.

[0055] According to one embodiment, the first HAL (231) and the second HAL (232) may include a software layer that provides an interface between the OS and the hardware. For example, the first HAL (231) and the second HAL (232) may include a software layer that provides an interface between the second OS (242) and the hardware. The first HAL (231) and the second HAL (232) may abstract the interaction between the second OS (242) and the hardware, thereby allowing the second OS (242) to operate without having to know the specific operation method of the hardware.

[0056] According to one embodiment, the second OS (242) can access hardware through the second HAL (232). The second OS (242) can access the hard drive through the first HAL (231) even without knowing details about the manufacturer or model of the actual hard drive. Furthermore, the first OS (241) can access hardware through the adapter (220) and the first HAL (231).

[0057] An adapter (220) according to one embodiment may include an interface that converts the first OS (241) to operate using the second HAL (232).

[0058] The data storage unit (250) is a data space shared by the first OS (241) and the second OS (242), and can store raw data for the first OS (241) and the second OS (242). For example, the data storage unit (250) can store an update image for the first OS and an update image for the second OS. However, the present invention is not limited thereto.

[0059] FIG. 3 is a drawing for explaining the operation of a display device according to one embodiment.

[0060] Referring to FIG. 3, a display device (100) according to one embodiment can drive a first OS (311) stored in a first partition as a host OS and drive a second OS (312) stored in a second partition as a guest OS.

[0061] The first OS (311) can be driven using the HAL adapter (320) for the first OS and the first HAL (331). For example, the first kernel for the first OS (311) can be called by a boot loader, and the first OS (311) can be booted using the adapter (320) and the first HAL (331).

[0062] Additionally, the second OS (312) can be operated in a container environment. For example, the display device (100) according to one embodiment can operate the second OS (312) in container mode based on container mode configuration data (Container mode config).

[0063] Container mode according to one embodiment may mean that the second OS (312) runs as a guest OS in a container environment. Running the second OS (312) in a container environment may mean that the second OS (312) is run in an independent environment using virtualization technology without directly installing the second OS (312) on physical hardware. This independent environment may be referred to as a container, and the container may provide a virtualized OS environment. The container may package an application and all components necessary for the application to operate (e.g., code, libraries, configuration files, etc.) and run them in an environment isolated from other systems. The container may share the kernel of the host OS, but may maintain an independent environment from other containers.

[0064] According to one embodiment, the second OS (312) can be booted as a guest OS using container mode configuration data and the first HAL (331).

[0065] According to one embodiment, the HAL for the second OS (312) may be configured as a dual including a first HAL (331) and a second HAL (332). Accordingly, the first OS and the second OS may be driven using the first HAL (331) and the second HAL (332), respectively. Since the HALs are configured as dual, when the first OS (311) is driven using the first HAL (331), the second OS (312) may be updated using the second HAL (332), and when the second OS (312) is driven using the second HAL (332), the first OS (311) may be updated using the first HAL (331).

[0066] In addition, since the first OS (311) and the second OS (312) use the same type of HAL (HAL for the second OS), no collision may occur even when they are run simultaneously.

[0067] Figure 4 is a flowchart illustrating a method of operating a display device according to one embodiment.

[0068] Referring to FIG. 4, a display device (100) according to one embodiment can determine a boot mode (S410).

[0069] A display device (100) according to one embodiment can identify an OS that requires an update. For example, the display device (100) can identify whether an update is required for a first OS or a second OS.

[0070] The display device (100) may operate in the first boot mode when a second OS update is required, in the third boot mode when a first OS update is required, and in the second boot mode when updates to the first OS and the second OS are not required. However, this is not limited thereto.

[0071] According to one embodiment, the display device (100) can boot the first OS when operating in the first boot mode (S420). For example, the first kernel (the first OS kernel) is called by the boot loader, and the first OS can be booted using the HAL adapter and the first HAL for the first OS.

[0072] According to one embodiment, the display device (100) can display a first home screen for the first OS when booting of the first OS is completed (S430).

[0073] For example, the first home screen is a screen provided by the first operating system, which may be displayed full screen or on a portion of the screen. The first home screen may include various functions, services, applications, etc. provided by the first operating system.

[0074] A display device (100) according to one embodiment can perform an update of a second OS in the background while a first OS is running in the foreground (S440).

[0075] The operation of performing an update of the second OS will be described in detail with reference to Fig. 9.

[0076] When the display device (100) according to one embodiment operates in the second boot mode, the first OS can be driven so that the first OS operates as a host OS, and the second OS can be driven so that the second OS operates as a guest OS (S450).

[0077] For example, a first kernel (first OS kernel) may be called by a boot loader, and the first OS may be booted using a HAL adapter for the first OS and the first HAL. In addition, a second OS may be booted based on the first HAL using a container. At this time, the second OS may be booted using a first mode configuration file (e.g., Container Mode Config). The first mode configuration file may include settings or data necessary to run the second OS as a guest OS.

[0078] According to one embodiment, the display device (100) can display a second home screen when the booting of the first OS and the second OS is completed (S460).

[0079] For example, the second home screen may include various functions, services, applications, etc. provided by the first OS and the second OS.

[0080] According to one embodiment, the display device (100) can boot the second OS when operating in the third boot mode (S470).

[0081] For example, a second kernel (second OS kernel) may be called by a boot loader, and the second OS may be booted using the second HAL. At this time, the second OS may be booted using a second mode configuration file (e.g., Standalone Mode Config). The second mode configuration file may include settings or data necessary to run the second OS as a host OS. However, the present invention is not limited thereto.

[0082] Even when the second OS boots independently, the second OS can run as a host OS, so it can have more privileges and security can be guaranteed than when it runs as a guest OS.

[0083] According to one embodiment, the display device (100) can display a third home screen for the second OS when booting of the second OS is completed (S480).

[0084] For example, the third home screen is a screen provided by the second OS, which may be displayed full screen or on a portion of the screen. The third home screen may include various functions, services, applications, etc. provided by the second OS, but is not limited thereto.

[0085] A display device (100) according to one embodiment can perform an update of a first OS in the background while a second OS is running in the foreground (S490).

[0086] The operation of performing an update of the first OS will be described in detail with reference to Fig. 8.

[0087] FIG. 5 is a diagram showing a first home screen according to one embodiment.

[0088] According to one embodiment, the display device (100) can boot and drive only the first OS when operating in the first boot mode.

[0089] When the booting of the first OS is completed, the display device (100) can display the first home screen (510) as shown in FIG. 5.

[0090] According to one embodiment, the first home screen (510) is a screen provided by the first OS, and may be displayed in full screen or on a portion of the screen. The first home screen (510) may include various functions, services, applications, etc. provided by the first OS. For example, the first home screen may include a first application list (520) indicating applications that have been installed or can be installed through the first OS. By selecting any one of the items included in the first application list (520), the user can easily execute the application corresponding to the selected item.

[0091] According to one embodiment, the display device (100) can display a first home screen (510) in the foreground when operating in the first boot mode, thereby allowing a user to use functions, services, applications, etc. provided by the first OS, and can perform updates of the second OS in the background.

[0092] FIG. 6 is a diagram showing a second home screen according to one embodiment.

[0093] According to one embodiment, the display device (100) can boot and drive a first OS and a second OS when operating in a second boot mode. For example, the display device (100) can drive the first OS so that the first OS operates as a host OS, and can drive the second OS so that the second OS operates as a guest OS.

[0094] When the booting of the first OS and the second OS is completed, the display device (100) can display the second home screen (610) as shown in FIG. 6.

[0095] A second home screen (610) according to one embodiment may include various functions, services, applications, etc. provided by the first OS and the second OS. For example, the second home screen (610) may include a second application list (620) indicating applications that are already installed or installable through the first OS and applications that are already installed or installable through the second OS.

[0096] Compared to the first application list (520) included in the first home screen (510) illustrated in FIG. 5, the second application list (620) included in the second home screen (610) illustrated in FIG. 6 may further include applications that are already installed or installable through the second OS in addition to the first application list (520). However, this is not limited thereto.

[0097] By selecting any of the items included in the second application list (620), the user can easily launch the application corresponding to the selected item. Accordingly, when booting the OSs in the second boot mode, the user can utilize all applications provided by the first OS or the second OS.

[0098] FIG. 7 is a diagram showing a third home screen according to one embodiment.

[0099] According to one embodiment, the display device (100) can boot and drive only the second OS when operating in the third boot mode.

[0100] When the booting of the second OS is completed, the display device (100) can display the third home screen (710) as shown in FIG. 7.

[0101] According to one embodiment, the third home screen (710) is a screen provided by the second OS, and may be displayed in full screen or on a portion of the screen. The third home screen (710) may include various functions, services, applications, etc. provided by the second OS. For example, the third home screen may include a third application list (720) indicating applications that have been installed or can be installed through the second OS. By selecting any one of the items included in the third application list (720), the user can easily execute the application corresponding to the selected item.

[0102] According to one embodiment, when the display device (100) operates in the third boot mode, it displays the third home screen (710) in the foreground, thereby allowing the user to use functions, services, applications, etc. provided by the second OS, and performs updates of the first OS in the background.

[0103] FIG. 8 is a diagram illustrating a method for a display device according to one embodiment to perform an update of a first OS.

[0104] Referring to FIG. 8, the display device (100) according to one embodiment can perform booting in a third boot mode. For example, the display device (100) can boot the second OS to operate as a host OS (second OS-only boot). The second kernel (second OS kernel) is called by a boot loader, and the second OS can be booted using the second HAL.

[0105] When the booting of the second OS is completed, the display device (100) can display the home screen (third home screen (810)) of the second OS on the display. The display device (100) can execute functions, services, applications, etc. provided by the second OS in the foreground.

[0106] According to one embodiment, the display device (100) can perform an update of the first OS in the background. For example, the display device (100) can download an update image (820) for the first OS from an external server (830) that provides the first OS. The downloaded first OS update image (820) can be stored in the data storage (250). While the display device (100) is running on the second OS, the space where the first kernel, the HAL adapter for the first OS, the first HAL, and the first OS are stored can be idle. The display device (100) can update the first kernel, the HAL adapter for the first OS, the first HAL, and the first OS using the stored first OS update image (820).

[0107] FIG. 9 is a diagram illustrating a method for a display device according to one embodiment to perform an update of a second OS.

[0108] Referring to FIG. 9, a display device (100) according to one embodiment may perform booting in a first boot mode. For example, the display device (100) may boot the first OS to operate as a host OS (first OS-only booting). The first kernel (first OS kernel) is called by a boot loader, and the first OS may be booted using a HAL adapter for the first OS, the first HAL.

[0109] When the booting of the first OS is completed, the display device (100) can display the home screen (first home screen (910)) of the first OS on the display. The display device (100) can execute functions, services, applications, etc. provided by the first OS in the foreground.

For example, the display device (100) can download an update image (920) for the second OS from an external server (930) that provides the second OS. The downloaded second OS update image (920) can be stored in the storage unit (250). While the display device (100) is running with the first OS, the space where the second kernel, the second HAL, and the second OS are stored can be idle. The display device (100) can update the second kernel, the second HAL, and the second OS using the stored second OS update image (920). In addition, the display device (100) can copy the updated first HAL (940) to the second HAL (950) to update the second HAL (950).

[0111] FIG. 10 is a drawing showing an example of a display device displaying an OS update settings menu according to one embodiment.

[0112] Referring to FIG. 10, a display device (100) according to one embodiment can display a menu screen that can set an OS update method based on user input.

[0113] The menu screen (1010) may include a menu that can set whether to automatically update the OSs according to one embodiment. For example, if the user selects the On item (1020) corresponding to the automatic update of the first OS included in the menu screen, the display device (100) can perform an automatic update of the first OS. If the automatic update of the first OS is set, the display device (100) can automatically detect whether an update of the first OS is required, such as when the current version of the first OS stored or installed in the display device (100) is not the latest version, or when a bug fix or security update is required. If an update of the first OS is required, the display device (100) can automatically perform an update of the first OS. For example, if an update of the first OS is required, the display device (100) can boot in the third boot mode and perform an update of the first OS in the background without a separate request from the user.

[0114] In addition, when the user selects the On item (1030) corresponding to the second OS automatic update included in the menu screen, the display device (100) can perform an automatic update of the second OS. When the automatic update of the second OS is set, the display device (100) can automatically detect whether an update of the second OS is required, such as when the current version of the second OS stored or installed in the display device (100) is not the latest version, or when a bug fix or security update is required. When an update of the second OS is required, the display device (100) can automatically perform an update of the second OS. For example, when an update of the second OS is required, the display device (100) can boot in the first boot mode and perform an update of the second OS in the background without a separate request from the user.

[0115] The menu screen (1010) may include items for manually updating OSs according to one embodiment.
