The server 400 may provide various content and interactive features to the display device 200. The server 400 may be a cluster or multiple clusters, and may include one or more types of servers.

[0036] Figure 2 An exemplary configuration block diagram of a control device 100 according to an exemplary embodiment is shown. Figure 2 As shown, the control device 100 includes at least one of a controller 110, a communication interface 130, a user input / output interface 140, a memory, and a power supply. The control device 100 can receive user input operation commands and convert the operation commands into commands that the display device 200 can recognize and respond to, thus acting as an intermediary for interaction between the user and the display device 200.

[0037] like Figure 3 The display device 200 includes at least one of the following: a tuner / demodulator 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a data connection interface. The data connection interface is connected to the display device body.

[0038] In this embodiment of the application, the data connection interface refers to the interface on the display device body used for data transmission and interaction. Through this interface, the first external device can communicate with the display device body to realize functions such as data reading and writing, and instruction transmission, so that the first external device can provide data to the display device body or receive control from the display device body.

[0039] In some embodiments, the controller includes a processor, a video processor, an audio processor, a graphics processor, RAM, ROM, and a first data connection interface to an nth data connection interface for input / output.

[0040] The display 260 includes a display screen assembly for presenting images, a driving assembly for driving image display, a component for receiving image signals from the controller output, and a user interface for displaying video content, image content, menu control interface, and user control UI.

[0042] The communicator 220 is a component used to communicate with external devices or servers according to various communication protocol types. For example, the communicator may include at least one of the following: a Wi-Fi module, a Bluetooth module, a wired Ethernet module, other network communication protocol chips or near-field communication protocol chips, and an infrared receiver. The display device 200 can establish the transmission and reception of control signals and data signals with the external control device 100 or the server 400 through the communicator 220.

[0043] Detector 230 is used to collect signals from the external environment or to interact with the external environment. For example, detector 230 includes a light receiver, a sensor for collecting ambient light intensity; or, detector 230 includes an image acquisition device, such as a camera, which can be used to collect external environmental scenes, user attributes, or user interaction gestures; or, detector 230 includes a sound acquisition device, such as a microphone, for receiving external sounds. In this embodiment of the application, the external device interface 240 may include: a first external device interface and at least one second external device interface, wherein the first external device interface is used to connect to a first external device and the at least one second external device interface is used to connect to a second external device.

[0044] The first external device interface is an interface on the display device used to connect to the first external device. It is a bridge connecting the first external device to the display device body or other second external devices. By controlling its connected objects, the first external device can switch between different devices.

[0045] In this embodiment of the application, the first external device interface includes a USB-A interface, and the second external device interface includes one or more of USB-B and Type-C.

[0046] In this embodiment, the first external device refers to an external device connected to the first external device interface, such as a USB flash drive, mouse, or keyboard. These devices have different functions; the USB flash drive is used to store and transfer data, while the mouse and keyboard are used to input operation commands. By connecting to different devices, they achieve corresponding functions. The second external device includes a terminal device. The terminal device can be a computer, tablet, mobile terminal, etc.

[0047] In some embodiments, the external device interface 240 may include, but is not limited to, one or more interfaces such as: High Definition Multimedia Interface (HDMI), analog or data high-definition component input interface (component), composite video input interface (CVBS), and RGB port. It may also be a composite input / output interface formed by multiple of the above interfaces.

[0048] The tuner / demodulator 210 receives broadcast television signals via wired or wireless means, and demodulates audio and video signals, such as EPG data signals, from multiple wireless or wired broadcast television signals.

[0049] In some embodiments, the controller 250 and the tuner 210 may be located in different separate devices, that is, the tuner 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0050] The controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200. For example, in response to receiving a user command to select a UI object to display on the monitor 260, the controller 250 can perform operations related to the object selected by the user command.

[0051] In some embodiments, the controller includes at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), RAM (Random Access Memory), ROM (Read-Only Memory), a first to an nth interface for input / output, a communication bus, etc.

[0052] Users can input commands through a graphical user interface (GUI) displayed on the monitor 260, and the user input interface receives the user input commands through the GUI. Alternatively, users can input commands by entering specific sounds or gestures, and the user input interface receives the user input commands by recognizing the sounds or gestures through sensors.

[0053] A "user interface" is the medium through which an application or operating system interacts and exchanges information with the user. It converts information from its internal form to a form that the user can accept. A common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed graphically. It can be an icon, window, control, view, or other interface element displayed on the screen of an electronic device. Controls can include visual interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets.

[0054] In some embodiments, to enable user interaction, the display device 200 may run an operating system. The operating system is a computer program used to manage and control the hardware and software resources of the display device 200. The operating system can control the display device to provide a user interface; for example, the operating system can directly control the display device to provide a user interface, or it can provide a user interface by running an application. The operating system also allows users to interact with the display device 200.

[0055] It should be noted that the operating system can be a native operating system based on a specific operating platform, a third-party operating system that is deeply customized based on a specific operating platform, or an independent operating system specifically developed for display devices.

[0056] An operating system can be divided into different modules or levels based on the functions it implements, for example... Figure 4 As shown, in some embodiments, the system is divided into four layers, from top to bottom: the Applications layer (referred to as the "Application Layer"), the Application Framework layer (referred to as the "Framework Layer"), the System Library layer, and the Kernel layer.

[0057] In some embodiments, at least one application runs in the application layer. This application may include: application 1, application 2, application 3, application 4, etc. These applications may be built-in Windows programs, system settings programs, or clock programs; they may also be applications developed by third-party developers. For example, application 1 may be a karaoke application, and application 2 may be a video application. In specific implementations, the application packages in the application layer are not limited to the examples above.

[0058] The framework layer provides application programming interfaces (APIs) and a programming framework for applications. The application framework layer includes predefined functions. It acts as a central processing unit, determining the actions taken by applications within the application layer. Applications can access system resources and obtain system services during execution through the API interface.

[0059] like Figure 4As shown, the application framework layer in this embodiment includes managers, content providers, etc., wherein the managers include at least one of the following modules: ActivityManager, which interacts with all activities running in the system; LocationManager, which provides access to system location services for system services or applications; PackageManager, which retrieves various information related to application packages currently installed on the device; NotificationManager, which controls the display and clearing of notification messages; and WindowManager, which manages icons, windows, toolbars, wallpapers, and desktop widgets on the user interface.

[0060] In some embodiments, the Activity Manager manages the lifecycle of individual applications and common navigation and back functions, such as controlling application exit, opening, and back actions. The Window Manager manages all window programs, such as obtaining the screen size, determining if a status bar is present, locking the screen, capturing the screen, and controlling display window changes (e.g., shrinking the display window, shaking the display, distorting the display, etc.).

[0061] In some embodiments, the system runtime library layer provides support for the upper layer, namely the framework layer. When the framework layer is used, the Android operating system runs the C / C++ libraries contained in the system runtime library layer to implement the functions that the framework layer needs to perform.

[0062] In some embodiments, the kernel layer is a layer between hardware and software. For example... Figure 4 As shown, the kernel layer includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver.

[0063] To facilitate a further understanding of the technical solutions in some embodiments of this application, the technical solutions of the display device and control method, and how these solutions solve the aforementioned technical problems, are described in detail below with reference to specific embodiments and accompanying drawings. The embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application.

[0064] Figure 5 A flowchart of a control method in a display device provided in an embodiment of this application is shown below. Figure 5As shown, the controller is configured to perform the following steps: Step S501: Identify the target connection interface to which the first external device is to be connected, wherein the target connection interface includes: a data connection interface or the second external device interface.

[0065] In this embodiment, the target connection interface is the object that the controller needs to determine and ultimately control the first external device interface to connect to. It can be a data connection interface on the display device itself, or one of at least one second external device interface. The selection of this interface determines which device the first external device will establish a connection with. Each interface corresponds to a channel; during switching control, this can also be referred to as channel switching, and determining the interface can also be called determining the channel.

[0066] In this embodiment, the controller obtains the target connection interface through internally preset programs and logic. First, the controller detects the current interface switching mode, which can be either automatic or manual. In automatic switching mode, the controller obtains the current signal source channel. The signal source channel is usually related to the source of the image currently displayed on the display device; different signal source channels correspond to different devices or data sources. The controller internally stores a mapping relationship between signal source channels and connection interfaces. By querying this mapping relationship, the connection interface corresponding to the current signal source channel can be determined, and this interface is the target connection interface. For example, if the homepage signal source channel corresponds to the data connection interface of the display device itself, and the HDMI signal source channel corresponds to the USB-B interface, then when the current signal source channel is HDMI, the target connection interface is the USB-B interface. In manual switching mode, the controller outputs a user selection interface. This interface displays the connection interface options in a graphical or textual manner, such as the display device's data connection interface, USB-B interface, Type-C interface, etc. Users select the desired connection interface on the interface using input devices on the display device (such as remote control, touch screen, etc.). After receiving the user's selection information, the controller determines the selected connection interface as the target connection interface. This interface switching mode can be called KVM mode, automatic switching mode can also be called automatic selection, and manual switching mode can also be called manual selection.

[0067] Step S502: If the target connection interface is the data connection interface, control the first external device interface to connect to the data connection interface so that the first external device is connected to the display device body.

[0068] In this embodiment, when the controller determines that the target connection interface is a data connection interface, it sends a control command to the interface control circuit inside the device. Upon receiving the command, the interface control circuit adjusts the connection state of the first external device interface to establish a physical connection with the data connection interface. This physical connection is typically achieved through pin contacts or signal line connections within the interface. Once the connection is established, the first external device can communicate with the display device body through the first external device interface to perform data transmission, device control, and other functions. For example, when the first external device is a USB flash drive, the data on the USB flash drive can be read or written by the display device body.

[0069] Step S503: If the target connection interface is the second external device interface, control the first external device interface to connect with the second external device interface so that the first external device is connected to the second external device connected to the second external device interface.

[0070] In this embodiment, when the target connection interface is a second external device interface, the controller also sends control commands to the interface control circuit. The interface control circuit adjusts the connection state of the first external device interface to establish a physical connection with the second external device interface. At this time, the first external device connects to the second external device connected to the second external device interface through the first external device interface. For example, if the second external device interface is connected to a mobile phone and the first external device is a USB flash drive, then the USB flash drive can interact with the mobile phone to perform functions such as file transfer.

[0071] The display device provided in this application embodiment realizes intelligent connection between external devices and different connection targets by dynamically switching the connection target of the first external device interface. Users do not need to manually plug and unplug devices, and the connection path can be automatically switched by the controller, which solves the problem of traditional displays requiring repeated plugging and unplugging of USB devices and improves efficiency.

[0072] The display device provided in this application allows users to easily connect the first external device to different devices (the display device itself or a second external device) simply by selecting and switching the target connection interface through the controller, without frequently plugging and unplugging the first external device. For example, when using a USB flash drive, users do not need to unplug the USB flash drive and plug it into another device; they can simply switch the connection interface on the display device to use the USB flash drive on different devices, greatly saving time and effort. By setting multiple second external device interfaces, the display device can connect to various types of second external devices, such as computers and mobile phones. This makes the display device not only a display terminal but also has data interaction and device collaboration functions.

[0073] In some embodiments, the controller acquires the target connection interface by means of the following steps: Step S5011: Obtain the current interface switching mode.

[0074] In this embodiment, the interface switching mode is a rule type for interface connection, divided into automatic switching mode (the system automatically matches the interface based on the signal source) and manual switching mode (the user actively selects the interface). The controller determines the current mode by reading system settings or user operation records.

[0075] Step S5012: Identify the target connection interface to which the first external device is to connect based on the interface switching mode.

[0076] In this embodiment of the application, the target link interface can be obtained by switching the interface mode.

[0077] In some embodiments, the controller identifies the target connection interface to which the first external device is to connect based on the interface switching mode, and is configured to: when the interface switching mode is an automatic switching mode, obtain the current signal source channel; and based on the mapping relationship between the signal source channel and the connection interface, identify the connection interface corresponding to the current signal source channel as the target connection interface.

[0078] In this embodiment, the automatic switching mode is an intelligent mode in which the system actively senses changes in the signal source and automatically matches the interface, without requiring manual intervention from the user. The signal source channel refers to the type of input source currently received by the display device, such as: HDMI / DP channel: video signals from devices like computers and game consoles; Type-C channel: direct signals from devices like mobile phones and tablets; display device body channel: the signal source of the display device's built-in system (such as Android). The mapping relationship is a preset rule base, used to bind specific signal source channels to physical interfaces. For example, "Home / System Interface" corresponds to the data connection interface of the display device body; "HDMI Input" corresponds to the USB-B interface; and "Type-C Input" corresponds to the Type-C interface.

[0079] In this embodiment, the controller monitors the input port status of the display device in real time through a hardware detection module. For example, when the user switches the display to "HDMI input," the hardware module recognizes the activation signal of the HDMI interface and feeds this status back to the controller. If the user connects a mobile phone via a Type-C cable and selects "screen mirroring," the controller detects the signal handshake protocol of the Type-C interface and confirms that the current signal source is a "Type-C channel." The controller then calls a preset mapping table to convert the detected signal source channel into the corresponding physical interface.

[0080] The method provided in this application embodiment allows users to switch the display screen (e.g., from computer HDMI to mobile phone Type-C screen mirroring) and the external device (e.g., USB flash drive, keyboard) will automatically follow the corresponding device without manual plugging or unplugging or menu operation.

[0081] In some embodiments, the controller identifies the target connection interface to which the first external device is to connect based on the interface switching mode, and is configured to: output a user selection interface with connection interface options when the interface switching mode is a manual switching mode; and determine the connection interface selected by the user as the target connection interface.

[0082] In this embodiment, the manual switching mode is a mode where the user actively specifies the interface connection rules through the interactive interface, complementing the passive adaptation logic of the "automatic switching mode." This mode is suitable for scenarios requiring precise control or special situations (such as temporary debugging or multi-device priority management). The user selection interface is an interactive window or menu generated by the display device, typically presented as icons, text lists, or touch buttons, containing all available connection interface options (such as "display device body interface," "USB-B," and "Type-C"). The connection interface options are the specific physical interface types listed in the interface, corresponding to the target devices that the display device can connect to (such as the display device's built-in system, external computers, mobile phones, etc.). Target connection interface: The final connection object determined by the user after selection through the interface. The first external device (such as a USB flash drive or keyboard) will establish a data channel with the target device through this interface.

[0083] In this embodiment, the user actively accesses the "KVM Settings" or "Interface Switching" menu via physical buttons on the display device (such as the menu button), remote control, or touchscreen. After selecting "Manual Switching Mode," the system calls the interface generation module. The interface typically adopts a hierarchical menu structure, displaying the current mode (manual) at the top and showcasing selectable interfaces (such as USB-B, Type-C, and the display device's own interface) in a list or icon format below, supporting scrolling or pagination. Some solutions add a "Default Settings" button to allow users to save frequently used configurations. The user completes the operation using directional keys, touch selection, or voice commands (such as "Select Type-C"). The interface highlights the selected item in real time and provides a confirmation prompt (such as an "OK" button). The controller receives the user's selection result, marks the selected interface as the "Target Connection Interface," and updates the system status record. The controller sends instructions to the interface control module to adjust the physical connection path of the first external device interface (such as USB-A) to establish an electrical connection with the target interface (such as USB-B), thus completing the data channel connection between the devices.

[0084] The method provided in this application allows users to actively select the interface according to actual needs (such as temporary debugging or device priority adjustment), avoiding connection errors that may occur in automatic mode due to signal source identification errors, thus improving operational reliability. Together with automatic mode, it forms an "automatic + manual" dual-mode system, meeting both daily high-efficiency needs and supporting personalized customization, expanding the applicable scenarios of the device (such as office, home entertainment, professional presentations, etc.).

[0085] In some embodiments, the controller is further configured to: Step S504: When the display device is triggered to sleep, obtain the current interface switching mode.

[0086] In this embodiment, "sleep mode" refers to the display device entering a low-power state (such as turning off the screen or pausing signal processing), but retaining some system functions (such as quick wake-up and interface state memory). Sleep mode is different from a complete shutdown and can usually be woken up by a button or signal.

[0087] In this embodiment, the user can trigger hibernation via remote control, power button, or system settings (e.g., long-pressing the power button to select "hibernate"). Upon receiving the hibernation command, the controller initiates the hibernation process and simultaneously records the current system state (e.g., signal source, interface connection status). The controller reads the current interface switching mode from the system configuration or user settings.

[0088] Step S505: If the current interface switching mode is automatic switching mode, obtain the signal source channel before the display device is in standby mode.

[0089] In this embodiment, the signal source channel before standby is the last signal source activated before the display device enters sleep mode (such as the HDMI channel when the user is using HDMI input).

[0090] In this embodiment, the controller obtains the last activated signal source channel before hibernation through a hardware detection module or system log. For example, if the user is watching video via HDMI, the signal source channel is "HDMI input"; if the user switches to Type-C screen mirroring and then hibernates, the channel is "Type-C input".

[0091] Step S506: Control the first external device interface to connect to the connection interface corresponding to the signal source channel before standby, and control the display device to enter sleep mode.

[0092] In this embodiment, the controller queries a preset mapping relationship (e.g., "HDMI input" → USB-B interface) based on the signal source channel before standby, and switches the first external device interface (e.g., USB-A) to the corresponding target connection interface (e.g., USB-B). The physical connection is established by the controller sending instructions to the interface switching matrix to adjust the internal electrical path (e.g., disconnecting the current connection and establishing a new connection). After the interface switching is completed, the controller turns off the screen backlight, pauses signal processing, and reduces the power consumption of the main control chip, putting the device into a sleep state.

[0093] The display device provided in this application embodiment allows external devices (such as keyboards and USB flash drives) to automatically connect to the device used before hibernation (such as computers) after the user wakes up the device, without the need to unplug or manually switch interfaces, thus improving the smoothness of operation. During hibernation, only the necessary interfaces are powered (such as the target interface), while other interfaces can be powered off, reducing standby power consumption and reducing potential safety risks (such as USB port leakage).

[0094] In some embodiments, the controller is also configured to perform the following steps: Step S507: When the current interface switching mode is manual switching mode, control the display device to enter sleep mode.

[0095] In this embodiment, in manual mode, the controller does not actively change the connection status of the first external device interface (e.g., maintaining connection to the user-specified USB-B interface). If the user previously connected the interface to an external computer via the interface, the connection is maintained during sleep mode; if connected to the display device itself, the display device interface remains active.

[0096] The display device provided in this application embodiment has a user-specified interface connection method in manual mode (such as temporarily connecting the keyboard to an external computer). This state is maintained during sleep mode to avoid connection interruption or misalignment caused by automatic adjustment.

[0097] In some embodiments, the controller is further configured to perform the following steps: Step S508: When the display device is triggered to standby mode, control the display device to enter standby mode.

[0098] In this embodiment of the application, the display device enters a low-power state during standby, the screen is turned off, some functions (such as signal processing and background tasks) are suspended, but the ability to wake up quickly (such as waking up via a button or signal) is retained.

[0099] Step S509: When the display device is triggered to shut down, control the display device to shut down, wherein when the display device is in standby or off state, all connection interfaces are powered off.

[0100] In this embodiment of the application, powering off the display device means completely cutting off the power to the device, stopping all hardware modules from working, and not retaining the system state (such as memory data and interface configuration).

[0101] In this embodiment of the application, the connection interface includes: a data connection interface, a first external device interface, and a second external device interface.

[0102] In some embodiments, the first external device interface includes a USB-A interface, and the second external device interface includes one or more of USB-B and Type-C. The first external device includes a USB flash drive, a mouse, or a keyboard, and the second external device includes a terminal device.

[0103] Based on the foregoing embodiments, this application provides a specific example where the display device is a novel display device integrating a display screen and a smart operating system, and also integrates two USB-A ports, one USB-B port, and one Type-C port. By switching, a USB device can be connected to the display device body via the local USB-A port. The display device body can automatically switch this USB device between devices such as the display's own Android system, a computer connected via USB-B, and a computer or mobile phone connected via Type-C, or set it to a specific channel, enriching user scenarios and improving the user experience.

[0104] In this embodiment, the USB device is connected to the display device via its own USB-A interface. The display device can switch this USB device between the following devices: the display device itself, a computer device with a Type-C port, and a computer device with a USB-B port.

[0105] In this embodiment, automatic selection based on signal source switching is supported, or manual selection by the user is also supported. The USB device connects to a computer device connected via a USB-A interface and a Type-C / USB-B port. The user can switch the USB flash drive to the computer and copy files (movies, APKs) to the USB flash drive without needing to unplug the flash drive. The user can then switch to the display device itself via the menu, making it convenient and quick.
