Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display device and a display control method thereof. Background Art

[0002] Currently, with the continuous development of technology, there are more and more power-on and wake-up solutions for display devices when the display devices are in standby mode.

[0003] In conventional technology, for a display device that supports a network power-on function (for example, compatible with the PJlink protocol), the display device can be awakened by a control device corresponding to the display device, or by a terminal device bound to the display device.

[0004] However, existing display device wake-up solutions require first turning on the display screen, then waiting for the operating system to start running before waking up the device. This wake-up process introduces a response delay, impacting the user experience. Furthermore, existing display device wake-up solutions require the system-on-chip (SOC) to remain powered even in standby mode, resulting in high power consumption and shortening the lifespan of the display device. Summary of the Invention

[0005] The present application provides a display device and a display control method thereof to solve the technical problems in the prior art of a wake-up delay in the display device and high power consumption of the display device in standby mode.

[0006] In a first aspect, some embodiments provide a display device, including:

[0007] A first power supply module is configured to supply power to the system-on-chip (SOC) so that the SOC is in a powered-on state;

[0008] The SOC is provided with a first network port and is configured to obtain a content data packet through the first network port when the SOC is in a powered-on state, and perform encoding and decoding processing on the content data packet to obtain content to be displayed;

[0009] a display, connected to the SOC, and configured to display content to be displayed;

[0010] The display device also includes:

[0011] The user input interface is configured to obtain a user's standby operation and generate a standby instruction; or

[0012] a detector configured to detect a power switching state of the first power module and generate a standby instruction if the power switching state indicates standby;

[0013] The SOC is further configured to obtain a standby instruction and enter a standby state in response to the standby instruction, and during the standby process, obtain a power-on instruction and enter a power-on state in response to the power-on instruction, and run an operating system of the display device;

[0014] The display device also includes:

[0015] The SOC is further configured to, in response to the standby instruction, control the first power module to stop supplying power to itself, so as to put itself into a power-off state;

[0016] A second power supply module is configured to supply power to the network-to-string module so that the network-to-string module is in a powered-on state;

[0017] The network-to-serial module is provided with a second network port and is configured to obtain a network startup data packet through the second network port when the module is in a powered-on state, and convert the network startup data packet into a network startup instruction; the startup instruction includes a network startup instruction;

[0018] Among them, when the SOC is in a power-off state, the network-to-serial module is in a power-on state.

[0019] In the above embodiment, after the SOC obtains the standby instruction, it responds to the standby instruction and enters the standby state, while controlling the first power supply module to no longer supply power to itself, so that it enters the power-off state. That is to say, when the display device is in the standby state, the SOC is powered off at the same time, which can save the power consumption of the display device in the standby state, thereby extending the service life of the SOC and the display device. On the other hand, by setting a network-to-serial module in the SOC, and when the SOC is in the power-off state, the network-to-serial module is in the power-on state. When the network-to-serial module is in the power-on state, it replaces the first network port in the SOC through its own second network port to obtain a network power-on data packet, converts the network power-on data packet into a network power-on instruction, and sends the network power-on instruction to the SOC, so that the SOC responds to the power-on instruction, enters the power-on state, and runs the operating system of the display device to realize the network power-on control of the display device, ensuring that the SOC can still respond to the network power-on instruction when it is in the power-off state. In addition, compared to the prior art solution of first controlling the display device to power on, then waiting for the display device's operating system to start running, and then waking up the display device screen, the SOC in this embodiment does not need to wait for the system to run, and can immediately and quickly respond to the network power-on command, thereby reducing the response delay of the display device. On the other hand, because this embodiment uses the second network port in the network-to-serial module to replace the first network port in the SOC in the power-off state during the network wake-up process, it can directly participate in the transmission of the network power-on command. Therefore, it can overcome the problem in the prior art that the first network port of the AC-powered display device is not powered and cannot support the network power-on function, thereby improving the versatility of the network power-on function.

[0020] In some embodiments, the display device further includes:

[0021] The network switching module is configured to switch the currently used network port of the display device from the first network port to the second network port before the SOC enters the power-off state; and after the SOC enters the power-on state, switch the currently used network port of the display device from the second network port back to the first network port.

[0022] In the above embodiment, a network switching module is provided to switch the network port connected to the router. This allows the network serial module to connect to the router and receive network startup data packets even when the SOC is powered off, ensuring that the network startup response can still be performed even when the SOC is powered off. In addition, when the SOC is powered on, it can connect to the router through the SOC's first network port to receive content data packets and implement the conventional content display function.

[0023] In some embodiments, the display device further includes:

[0024] The memory is configured to store a start / stop state of the network startup function; the start / stop state is an enabled state or a disabled state;

[0025] Among them, when the start-stop state is enabled and the SOC is in a power-off state, the network-to-string module is in a power-on state; and when the start-stop state is disabled, the network-to-string module is in a power-off state.

[0026] In the above embodiment, by introducing the start and stop states of the network startup function, the user can independently select and control the network startup function.

[0027] In some embodiments, the user input interface is further configured to obtain the user's power-on operation and generate a basic power-on instruction; or

[0028] The detector is further configured to detect a power switching state of the first power module and generate a basic power-on instruction if the power switching state indicates power-on;

[0029] Among them, the power-on instructions include basic power-on instructions;

[0030] Accordingly, the SOC, connected to the memory, is also configured as:

[0031] After the SOC enters the power-on state, the start / stop status of the network power-on function is obtained from the memory, and according to the start / stop status, the second power supply module is controlled to supply power to the network serial module to switch the working state of the network serial module; wherein the working state includes the power-on state and the power-off state.

[0032] In the above embodiment, when the display device is in the power-on state responding to the basic power-on command, the working state switching control of the network-to-serial module is controlled by the SOC, which can ensure the immediate acquisition and response of the network power-on data packet when the network power-on function is enabled, and realize the energy loss control of the network-to-serial module when the network power-on function is disabled.

[0033] In some embodiments, when the SOC controls the second power supply module to supply power to the network-to-string module according to the start / stop state to switch the working state of the network-to-string module, the SOC is specifically configured as follows:

[0034] When the start / stop state is the enabled state, controlling the second power supply module to supply power to the network transfer string module so that the network transfer string module enters the power-on state; and

[0035] When the start-stop state is the disabled state, the second power supply module is controlled to no longer supply power to the network-to-string module, so that the network-to-string module enters a power-off state.

[0036] In the above embodiment, the operating state of the network serial module is differentiated by configuring a memory to store the start and stop states of the network power-on state. Furthermore, when the network power-on state is disabled, the network serial module is set to power down, thereby avoiding energy waste caused by the network serial module remaining powered on when not required.

[0037] In some embodiments, when a network switching module is provided in the display device, the SOC is further configured to:

[0038] After controlling the second power supply module to supply power to the network-to-serial module according to the start / stop state, sending a first network port switching instruction to the network switching module;

[0039] The network switching module is further configured to obtain a first network port switching instruction, and in response to the first network port switching instruction, switch the currently used network port of the display device to the first network port.

[0040] In the above embodiment, a network switching module is set in the display device, and when the network power-on state is in the enabled state, the second power supply module is controlled to supply power to the network transfer module, and after power is supplied, the currently used network port is switched to the first network port; and, when the network power-on state is in the enabled state and the network transfer module sends a network power-on instruction to the SOC, the currently used network port is switched to the first network port, so that the SOC can obtain the content data packet when the display device is in the powered-on state, thereby avoiding the situation where the SOC cannot normally receive the content data packet due to the network port not being switched.

[0041] In some embodiments, the SOC is connected to the memory, and when executing the standby instruction and controlling the first power module to stop supplying power to the SOC so as to put the SOC into a power-off state, the SOC is further configured to:

[0042] In response to the standby instruction, the start / stop status of the network power-on function is obtained from the memory, and according to the start / stop status, the second power supply module is controlled to supply power to the network transfer string module to switch the working state of the network transfer string module, and the first power supply module is controlled to stop supplying power to itself to put itself into a power-off state;

[0043] The working state includes a power-on state and a power-off state.

[0044] In the above embodiment, when the SOC responds to a standby instruction, the SOC controls the working state switching of the network-to-serial module, thereby ensuring the immediate acquisition and response of the network power-on data packet when the network power-on function is enabled, and realizing the energy loss control of the network-to-serial module when the network power-on function is disabled.

[0045] In some embodiments, when the SOC controls the second power supply module to supply power to the network-to-string module according to the start / stop state to switch the working state of the network-to-string module, the SOC is specifically configured as follows:

[0046] When the start / stop state is the enabled state, controlling the second power supply module to supply power to the network transfer string module so that the network transfer string module enters the power-on state; and

[0047] When the start-stop state is the disabled state, the second power supply module is controlled to no longer supply power to the network-to-string module, so that the network-to-string module enters a power-off state.

[0048] The above embodiment describes the specific operations that occur after the SOC responds to a standby command: switching the network-to-serial module's operating state based on the start / stop state, and controlling the first power supply module to stop supplying power to the SOC. On the one hand, in response to the standby command, the SOC itself is powered down, avoiding energy waste caused by the SOC remaining powered on when it could be in standby mode. On the other hand, when the network power-on function is enabled, the network-to-serial module is controlled to power on to ensure the availability of the network power-on function.

[0049] In some embodiments, when a network switching module is provided in the display device, the SOC is further configured to:

[0050] After controlling the second power supply module to no longer supply power to the network transfer module, sending a first network port switching instruction to the network switching module; or, after controlling the second power supply module to supply power to the network transfer module, sending a second network port switching instruction to the network switching module;

[0051] The network switching module is also configured to obtain a first network port switching instruction and, in response to the first network port switching instruction, switch the currently used network port of the display device to the first network port; or, obtain a second network port switching instruction and, in response to the second network port switching instruction, switch the currently used network port of the display device to the second network port.

[0052] In the above embodiment, the network port switching control of the network switching module is performed by the SOC, so that on the one hand, when the network transfer serial module is in a power-off state, the SOC sends a first network port switching instruction to the network switching module to instruct the network switching module to switch the currently used network port to the first network port, so that the SOC can obtain content data packets when it is in a power-on state, and avoid the situation where the SOC cannot normally receive content data packets due to the failure to switch the network port; on the other hand, when the network transfer serial module is in a power-on state, the SOC sends a second network port switching instruction to the network switching module to instruct the network switching module to switch the currently used network port to the second network port to enable the network power-on function, so that the network transfer serial module can receive network power-on data packets and generate network power-on instructions.

[0053] In some embodiments, when a network switching module is provided in the display device, the network configuration information of the second network port is the same as the network configuration information of the first network port;

[0054] In a case where the display device is not provided with a network switching module, the first network configuration information of the second network port is different from the first network configuration information of the first network port, and the second network configuration information of the second network port is the same as the second network configuration information of the first network port;

[0055] The first network configuration information includes Internet Protocol (IP) address information; the second network configuration information includes other network configuration information except the IP address information.

[0056] The above embodiments provide configurations for the network configuration information of the first network port and the network configuration information of the second network port, both in the case where the display device is provided with a network switching module and in the case where the display device is not provided with a network switching module, thereby increasing the richness and diversity of the display control process. Furthermore, in the case where the display device is not provided with a network switching module, the first network configuration information of the second network port is configured to be different from the first network configuration information of the first network port. This can prevent the router from confusing the first network port with the second network port during network port switching, thereby facilitating accurate network port switching.

[0057] In some embodiments, the SOC is further provided with a first serial port, and the network-to-serial module is further provided with a second serial port; the first serial port is connected to the second serial port;

[0058] Accordingly, the SOC is further configured to monitor network changes of the display device, and synchronize target network configuration information to the second serial port via the first serial port when the network of the display device changes;

[0059] The target network configuration information is the network configuration information that requires the same configuration for the second network port and the first network port.

[0060] In the above embodiment, by setting a first serial port in the SOC and setting a second serial port in the network-to-serial module, and connecting the first serial port to the second serial port, real-time synchronization of network configuration information between the network-to-serial module and the SOC is achieved, thereby avoiding failure of the network startup function due to different network configuration information.

[0061] In some embodiments, the display device further includes:

[0062] An additional microcontroller unit MCU is connected to the network-to-serial module and the SOC, and is configured to obtain a network power-on instruction and generate a power-on signal in response to the network power-on instruction;

[0063] Accordingly, when the SOC obtains the power-on instruction and responds to the power-on instruction, enters the power-on state, and runs the operating system of the display device, it is specifically configured as follows:

[0064] A power-on signal is obtained, and in response to the power-on signal, a power-on state is entered and an operating system of the display device is run.

[0065] In the above embodiment, an additional microcontroller unit (MCU) is provided to receive a network power-on command sent by the network-to-serial module, generate a power-on signal in response to the network power-on command, and transmit the power-on signal to the SOC. This allows the display device to support the network power-on function by introducing an additional MCU with lower hardware cost, even when the existing MCU in the display device cannot be reused, thereby ensuring the availability of the network power-on function.

[0066] In a second aspect, some embodiments further provide a display control method,

[0067] The display device includes:

[0068] A first power supply module is configured to supply power to the system-on-chip (SOC) so that the SOC is in a powered-on state;

[0069] The SOC is provided with a first network port and is configured to obtain a content data packet through the first network port when the SOC is in a powered-on state, and perform encoding and decoding processing on the content data packet to obtain content to be displayed;

[0070] a display, connected to the SOC, and configured to display content to be displayed;

[0071] The display device also includes:

[0072] The user input interface is configured to obtain a user's standby operation and generate a standby instruction; or

[0073] a detector configured to detect a power switching state of the first power module and generate a standby instruction if the power switching state indicates standby;

[0074] The SOC is further configured to obtain a standby instruction and enter a standby state in response to the standby instruction, and during the standby process, obtain a power-on instruction and enter a power-on state in response to the power-on instruction, and run an operating system of the display device;

[0075] The display device also includes:

[0076] The SOC is further configured to, in response to the standby instruction, control the first power module to stop supplying power to itself, so as to put itself into a power-off state;

[0077] A second power supply module is configured to supply power to the network-to-string module so that the network-to-string module is in a powered-on state;

[0078] The network-to-serial module is provided with a second network port and is configured to obtain a network startup data packet through the second network port when the module is in a powered-on state, and convert the network startup data packet into a network startup instruction; the startup instruction includes a network startup instruction;

[0079] Among them, when the SOC is in the power-off state, the network-to-string module is in the power-on state;

[0080] The display control method includes:

[0081] Obtain a standby instruction, and enter a standby state in response to the standby instruction; during the standby process, obtain a network power-on instruction, and enter a power-on state in response to the network power-on instruction, and run the operating system of the display device.

[0082] In the above embodiment, after the SOC obtains the standby instruction, it responds to the standby instruction and enters the standby state, while controlling the first power supply module to no longer supply power to itself, so that it enters the power-off state. That is to say, when the display device is in the standby state, the SOC is powered off at the same time, which can save the power consumption of the display device in the standby state, thereby extending the service life of the SOC and the display device. On the other hand, by setting a network-to-serial module in the SOC, and when the SOC is in the power-off state, the network-to-serial module is in the power-on state. When the network-to-serial module is in the power-on state, it replaces the first network port in the SOC through its own second network port to obtain a network power-on data packet, converts the network power-on data packet into a network power-on instruction, and sends the network power-on instruction to the SOC, so that the SOC responds to the power-on instruction, enters the power-on state, and runs the operating system of the display device to realize the network power-on control of the display device, ensuring that the SOC can still respond to the network power-on instruction when it is in the power-off state. In addition, compared to the prior art solution of first controlling the display device to power on, then waiting for the display device's operating system to start running, and then waking up the display device screen, the SOC in this embodiment does not need to wait for the system to run, and can immediately and quickly respond to the network power-on command, thereby reducing the response delay of the display device. On the other hand, because this embodiment uses the second network port in the network-to-serial module to replace the first network port in the SOC in the power-off state during the network wake-up process, it can directly participate in the transmission of the network power-on command. Therefore, it can overcome the problem in the prior art that the first network port of the AC-powered display device is not powered and cannot support the network power-on function, thereby improving the versatility of the network power-on function.

[0119] In some embodiments, the user input interface 280 may be configured to receive a command input from a user. For example, the user input interface 280 may be configured to obtain a standby operation input from a user and generate a standby command.

[0120] Figure 3 Some embodiments of this application provide Figure 1 The hardware configuration diagram of the control device in the figure is as follows. Figure 3 As shown, the control device 100 may include: a controller 110, a communication interface 130, a user input / output interface, a memory, and a power supply.

[0121] The control device 100 is configured to control the display device 200 , and can receive user input operation instructions, and convert the operation instructions into instructions that the display device 200 can recognize and respond to, playing the role of an interactive intermediary between the user and the display device 200 .

[0122] In some embodiments, the control device 100 may be a smart device. For example, the control device 100 may be installed with various applications for controlling the display device 200 according to user needs.

[0123] In some embodiments, as Figure 1 As shown, the mobile terminal 300 or other intelligent electronic devices can play a similar function as the control device 100 after installing the application for controlling the display device 200 .

[0124] Controller 110 includes a processor 112, random access memory (RAM) 113, read-only memory (ROM) 114, a communication interface 130, and a communication bus. Controller 110 is used to control the operation and functionality of control device 100, facilitate communication between its components, and process both internal and external data.

[0125] Under the control of the controller 110, the communication interface 130 communicates control signals and data signals with the display device 200. The communication interface 130 may include at least one of a WiFi chip 131, a Bluetooth module 132, an NFC (Near Field Communication) module 133, or other near field communication modules.

[0126] The user input / output interface 140 includes at least one of a microphone 141 , a touch panel 142 , a sensor 143 , a button 144 and other input interfaces.

[0127] In some embodiments, the control device 100 includes at least one of a communication interface 130 and an input / output interface 140. The control device 100 is configured with the communication interface 130, such as a WiFi, Bluetooth, or NFC module, to encode user input commands via the WiFi protocol, Bluetooth protocol, or NFC protocol and transmit them to the display device 200.

[0128] The memory 190 is used to store various operating programs, data and applications for driving and controlling the control device 100 under the control of the controller. The memory 190 can store various control signal instructions input by the user.

[0129] In some embodiments, the memory 190 may be used to store the start / stop status of the network power-on function of the display device 200 , wherein the start / stop status is an enabled state or a disabled state.

[0130] The power supply 180 is used to provide operating power support for each component of the control device 100 under the control of the controller.

[0131] In some embodiments, the power supply 180 can be used to power the entire display device 200, or some modules in the display device 200. For example, the power supply may include a first power supply module for powering the SOC in the display device to keep the SOC in a powered-on state; the power supply may also include a second power supply module for powering the network-to-serial module in the display device to keep the network-to-serial module in a powered-on state. The network-to-serial module is a network-to-serial module, which is an embedded device module that can convert network data to serial port data and vice versa.

[0132] Accordingly, in some embodiments, Figure 2 The detector 230 may be configured to detect the power switching state of the first power module, and generate a standby instruction when the power switching state of the first power module indicates standby.

[0133] To facilitate user interaction, in some embodiments, 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 may provide a user interface (to control the display device), allow the user to interact with the display device 200, and support the running of various application programs.

[0134] It should be noted that the operating system may be a native operating system based on a specific operating platform, or a third-party operating system deeply customized based on a specific operating platform, or an independent operating system specially developed for the display device.

[0135] The operating system can be divided into different modules or layers according to the functions implemented, e.g. Figure 4 As shown, in some embodiments, the system is divided into four layers, from top to bottom: the application layer (abbreviated as "application layer"), the application framework layer (abbreviated as "framework layer"), the system library layer and the kernel layer.

[0136] In some embodiments, the application layer provides services and interfaces for applications, enabling the display device 200 to run applications and interact with the user based on these applications. The application layer can host at least one application, which can include built-in window programs, system settings programs, clock programs, and other applications provided by the operating system, or applications developed by third-party developers. In specific implementations, the application packages in the application layer are not limited to the examples above.

[0137] The framework layer provides applications with an application programming interface (API) and programming framework. The application framework layer includes predefined functions. The application framework layer acts as a processing center, determining the actions taken by applications in the application layer. Through the API, applications can access system resources and services during execution.

[0138] like Figure 4As shown, in the embodiment of the present application, the application framework layer includes a view system, managers, content providers, etc., wherein the view system can design and implement the interface and interaction of the application, and the view system includes lists, grids, text boxes, buttons, etc. The manager includes at least one of the following modules: an activity manager for interacting with all activities running in the system; a location manager for providing system services or applications with access to the system location service; a package manager for retrieving various information related to the application packages currently installed on the device; a notification manager for controlling the display and clearing of notification messages; and a window manager for managing icons, windows, toolbars, wallpapers, and desktop widgets on the user interface.

[0139] In some embodiments, the activity manager is used to manage the lifecycle of each application and common navigation back functions, such as controlling application exit, opening, and back. The window manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, taking screenshots, and controlling changes in display windows, such as shrinking, shaking, or distorting the display window.

[0140] In some embodiments, the system runtime layer can provide support for the framework layer. When the framework layer is used, the operating system will run the instruction library contained in the system runtime layer, such as the C / C++ instruction library, to implement the functions to be implemented by the framework layer.

[0141] In some embodiments, the kernel layer is a functional layer between the hardware and software of the display device 200. The kernel layer can implement functions such as hardware abstraction, multitasking, and memory management. Figure 4 As shown, the kernel layer may be configured with hardware drivers, and the drivers included in the kernel layer may be at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB (Universal Serial Bus) driver, HDMI (High-Definition Multimedia Interface) driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0142] It should be noted that the above example is only a simple division of the operating system functions and does not constitute a limitation on the specific operating system form of the display device 200 in the embodiment of the present application. Depending on factors such as the function of the display device and the type of operating system, the number of levels and specific level types contained in the operating system may be expressed in other forms.

[0143] Figure 5 FIG is a structural diagram of a display device in some embodiments. Figure 5 The display device 200 includes a SOC 290, a first power module 1801, a user input interface 280, and a display 260. The SOC 290 is provided with a first network port 2901. The first power module 1801 and the user input interface 280 are respectively connected to the SOC 290; the SOC 290 is respectively connected to the display 260 and the router 500.

[0144] In some embodiments, the first power module 1801 is configured to supply power to the SOC 290, thereby keeping the SOC 290 in a powered-on state. The first network port 2901 is configured to, when the first network port 2901 is powered on, obtain content data packets through the first network port 2901, perform encoding and decoding on the content data packets, obtain content to be displayed, and input the content to be displayed to the display 260 for display by the display 260. Accordingly, the display 260 is configured to display the content to be displayed.

[0145] The content data packet encapsulates images, videos or other graphic data that need to be displayed on the display device 200 .

[0146] In some embodiments, the SOC 290 is further configured to obtain a standby instruction and enter a standby state in response to the standby instruction, and during the standby state, obtain a power-on instruction and enter a power-on state in response to the power-on instruction, and run the operating system of the display device 200. The standby instruction is used to instruct the SOC 290 to enter the standby state, and the power-on instruction is used to instruct the SOC 290 to enter the power-on state.

[0147] Optionally, the user input interface 280 in the display device 200 may generate a standby instruction or a power-on instruction in response to a user operation (such as a touch operation).

[0148] Figure 6 FIG1 is a structural diagram of another display device in some embodiments. Figure 6The display device 200 includes a SOC 290, a first power module 1801, a detector 230, and a display 260. The SOC 290 is provided with a first network port 2901. The first power module 1801 and the detector 230 are respectively connected to the SOC 290; the SOC 290 is respectively connected to the display 260 and the router 500.

[0149] In some embodiments, the detector 230 in the display device 200 can detect the power switching state of the first power module 1801 and generate a standby instruction when the power switching state indicates standby. The power switching state includes a standby state and a power-on state. Accordingly, when the power switching state is the standby state, the display device 200 is instructed to be in standby mode; when the power switching state is the power-on state, the display device 200 is instructed to be powered on.

[0150] In the above-mentioned optional embodiments, if the SOC 290 remains in the power supply state after entering the standby state, the display device 200 will consume a large amount of power as a whole, thereby affecting the service life of the SOC 290 and the service life of the display device 200 as a whole. Based on this, when the display device 200 is in the standby state, a display control method is urgently needed that can reduce device power consumption and does not affect the standby wake-up of the display device 200.

[0151] Figure 7 is a structural diagram of a display device in some embodiments. Figure 7 The display device 200 further includes a second power supply module 1802 and a network serial module 2100; the network serial module 2100 is provided with a second network port 21001. The second power supply module 1802 is connected to the network serial module 2100; and the second network port 21001 is connected to the router 500.

[0152] In some embodiments, the SOC 290 is also configured to, in response to a standby instruction sent by the detector 230, control the first power supply module 1801 to no longer supply power to itself, so that it enters a power-off state and a standby state; the second power supply module 1802 is configured to supply power to the network-to-string module 2100, so that the network-to-string module 2100 is in a power-on state.

[0153] In some embodiments, the power-on command includes a network power-on command, where the network power-on command is an instruction to power on the display device 200 via network control (e.g., a mobile application). Accordingly, the network-to-serial module 2100 is configured to, while the module is powered on, receive a network power-on packet via the second network port 21001 and convert the packet into a network power-on command. The network power-on packet can be understood as a network packet specifically used to remotely wake up a display device in standby mode.

[0154] Specifically, the SOC 290 obtains a standby instruction and, in response to the standby instruction, enters a standby state and controls the first power supply module 1801 to stop supplying power to itself, so that it is in a power-off state, thereby saving power consumption of the display device 200 in the standby state. When the SOC 290 is in the power-off state, the network transfer module 2100 is in the power-on state. At this time, the network transfer module 2100 obtains a network power-on data packet through the second network port 21001 and converts the network power-on data packet into a network power-on instruction. The network transfer module 2100 sends the network power-on instruction to the SOC 290, so that the SOC 290 enters a power-on state in response to the network power-on instruction and runs the operating system of the display device 200. Furthermore, the SOC 290 obtains a content data packet through the first network port 2901, encodes and decodes the content data packet to obtain the content to be displayed, and displays the content to be displayed on the display 260 for the user to view.

[0155] In the above embodiment, after the SOC 290 obtains the standby instruction, it responds to the standby instruction and enters the standby state, and controls the first power module to no longer supply power to itself, so that it enters the power-off state. That is, when the display device 200 is in the standby state, the SOC 290 is powered off at the same time, which can save the power consumption of the display device 200 in the standby state, thereby extending the service life of the SOC 290 and the display device 200. On the other hand, by setting the network transfer string module 2100 in the SOC 290, and when the SOC 290 is in the power-off state, the network transfer string module 2100 is in the power-on state. At this time, the network transfer string module 2100 can obtain the network power-on data packet through the second network port 21001, and convert the network power-on data packet into a network power-on instruction and send it to the SOC 290; the SOC 290 can respond to the network power-on instruction, enter the power-on state, and run the operating system of the display device 200, thereby achieving an immediate response to the network power-on instruction and waking up the display device 200 from standby. Compared to the prior art solution of first controlling the display device to power on, then waiting for the display device's operating system to start running, and then waking up the display 260 of the display device 200, the SOC 290 of this embodiment can instantly receive the network power-on command and respond to the network power-on command, directly entering the power-on state. There is no need to wait for the device to power on, nor is there a need to wait for the SOC 290 to pull up the operating system before responding to the network power-on command and displaying the screen, thereby reducing the wake-up delay of the display device 200. On the other hand, because this embodiment can transmit the network power-on command without the participation of the first network port during the network wake-up process, it can adapt to the situation where the SOC 290 is in standby and powered off, and is also applicable when the first network port of the AC-powered display device is not powered, thereby improving the versatility of the network power-on function.

[0156] Figure 8 is a structural diagram of a display device in some embodiments. Figure 8 SOC 290 includes a network switching module 2902, which is connected to router 500, first network port 2901, and second network port 21001. Network switching module 2902 can automatically or manually switch network-connected devices based on user needs or network status. For example, network switching module 2902 can be a switch.

[0157] In some embodiments, the network switching module 2902 is configured to switch the currently used network port of the display device 200 from the first network port 2901 to the second network port 21001 before the SOC 290 enters the power-off state, thereby replacing the first network port 2901 through the second network port 21001, and sending the network power-on data packet to the network transfer module 2100, so that the network transfer module 2100 converts the network power-on data packet into a network power-on instruction, and sends the network power-on instruction to the SOC 290, so that the SOC 290 responds to the network power-on instruction, enters the power-on state, and runs the operating system of the display device 200.

[0158] The network switching module 2909 is also configured to switch the currently used network port of the display device 200 from the second network port 21001 back to the first network port 2901 after the SOC 290 enters the power-on state, so that the SOC 290 can obtain the content data packet through the first network port 2901 when it is in the power-on state, and encode and decode the content data packet to obtain the content to be displayed, and output the content to be displayed to the display 260 so that the display 260 can display the content to be displayed, thereby avoiding abnormal content display.

[0159] In the above embodiment, the network switching module 2902 is provided to realize automatic switching of the network port connected to the router 500, so that when the SOC 290 is in the power-off state, the network serial module 2100 can connect to the router 500 and use the second network port 21001 provided by itself to replace the first network port 2901 in the SOC 290 to receive the network startup data packet. Therefore, when the SOC 290 is in the power-off state, the display device 200 can still respond to the network startup. In addition, when the SOC 290 is in the power-on state, the network switching module 2902 can switch the currently used network port back to the connection between the first network port 2901 in the SOC 290 and the router 500, thereby receiving the content data packet and realizing the conventional content display function.

[0160] Figure 9is a structural diagram of a display device in some embodiments. Figure 9 The SOC 290 is provided with a memory 2110, and the SOC 290 is connected to the memory 2110. The memory 2110 is configured to store the start / stop state of the network power-on function of the display device 200; wherein the start / stop state is an enabled state or a disabled state.

[0161] In some embodiments, when the start-stop state is enabled and the SOC 290 is in a power-off state, the network-to-string module 2100 is in a power-on state; and, when the start-stop state is disabled, the network-to-string module 2100 is in a power-off state.

[0162] It should be noted that if the display device 200 has a network power-on function, the user can adjust the start / stop state of the network power-on function of the display device 200 according to actual usage needs, thereby achieving independent control over whether the network power-on function is used. Furthermore, the start / stop state of the network power-on function is stored in the memory 2110, so that the device can maintain its own usage of the network power-on function.

[0163] It is worth noting that the switching control of the power-on state and the power-off state of the network-to-serial module 2100 can be achieved by reusing the SOC 290 in the display device 200. To ensure the smooth operation of the display device 200, the state switching control process of the SOC 290 for the network-to-serial module 2100 is at least partially different in different situations.

[0164] In some embodiments, when the display device 200 is in the power-on state through a basic power-on instruction, the SOC 290 will respond to the basic power-on instruction, enter the power-on state, and run the operating system of the display device, laying the foundation for the display device 200 to perform regular content display.

[0165] Continue to see Figure 5 In some optional embodiments, the user input interface 280 is further configured to obtain a user's power-on operation and generate the above-mentioned basic power-on instruction. The power-on operation can be triggered by a user through a touch operation, or by a mobile terminal 300 bound to the display device 200, or by a control device 100 matched with the display device.

[0166] Continue to see Figure 6 In some other optional embodiments, the detector 230 is further configured to detect the power switching state of the first power module, and generate the above-mentioned basic power-on instruction when the power switching state indicates power-on.

[0167] In some specific implementations, the basic power-on instruction may include at least one of a STR (Standby to Ready) power-on instruction and an AC / DC power-on instruction.

[0168] In some embodiments, see Figure 9 After SOC 290 receives the basic power-on command, SOC 290 enters the power-on state in response to the basic power-on command and runs the operating system of display device 200. At this point, display device 200 is in the power-on state. Accordingly, SOC 290 can also be configured to obtain the start / stop status of the network power-on function from memory 2110 after SOC 290 enters the power-on state, and control second power supply module 1802 to power network serial module 2100 based on the start / stop status, thereby switching the operating state of network serial module 2100. The operating state includes a power-on state and a power-off state.

[0169] Exemplarily, SOC 290 is specifically configured to: when the start / stop status of the network boot function stored in memory 2110 is enabled, control second power module 1802 to power network serial module 2100, so that network serial module 2100 is in a powered-on state, facilitating immediate acquisition and response of network boot data packets. When the start / stop status of the network boot function stored in memory 2110 is disabled, control second power module 1802 to stop powering network serial module 2100, so that network serial module 2100 is in a powered-off state, thereby avoiding unnecessary energy loss caused by network serial module 2100 continuing to operate when the network boot function is disabled.

[0170] In the above embodiment, memory 2110 is provided to store the start and stop states of the network power-on state. The operating state of network-to-serial module 2100 varies depending on the start and stop states. A specific method for switching the operating state of network-to-serial module 2100 based on the start and stop states after SOC 290 is powered on is also provided. In the above embodiment, when the network power-on state is disabled, network-to-serial module 2100 is controlled to enter a power-off state, thereby avoiding energy waste caused by the network-to-serial module 2100 remaining powered on.

[0171] Further, in some embodiments, see Figure 9 If the display device 200 is provided with a network switching module 2902, the SOC 290 may be further configured to, after controlling the second power supply module to supply power to the network-to-serial module according to the start / stop state, send a first network port switching instruction to the network switching module 2902. The first network port switching instruction is used to instruct the network switching module 2902 to switch the currently used network port of the display device 200 to the first network port 2901.

[0172] Optionally, when the display device 200 is currently powered on, after the SOC 290 enters the power-on state, if the network power-on state is enabled, the second power supply module 1802 is controlled to supply power to the network transfer serial module 2100, and after the network transfer serial module 2100 enters the power-on state, the first network port switching instruction is sent to the network switching module 2902. Accordingly, the network switching module 2902 is further configured to obtain the first network port switching instruction and, in response to the first network port switching instruction, switch the currently used network port of the display device 200 to the first network port 2901, so that the SOC 290 can connect to the router 500 through the first network port 2901, thereby obtaining content data packets, performing encoding and decoding processing on the content data packets, obtaining content to be displayed, and sending the content to be displayed to the display 260 for the display 260 to display the content to be displayed. The advantage of doing this is that when the display device 200 is turned on and the user enables the network power-on function, it can avoid the situation where the content data packet cannot be received normally due to the unavailability of the first network port of the SOC 290, thereby providing protection for the content display function of the display device 200.

[0173] Alternatively, when the display device 200 is currently powered on, after the SOC 290 enters the power-on state, if the network power-on state is disabled, the second power supply module 1802 is controlled to no longer supply power to the network transfer serial module 2100, and after the network transfer serial module enters the power-off state, the first network port switching instruction is sent to the network switching module 2902. Accordingly, the network switching module 2902 is further configured to obtain the first network port switching instruction and, in response to the first network port switching instruction, switch the currently used network port of the display device 200 to the first network port 2901, so that the SOC 290 can connect to the router 500 through the first network port 2901, thereby obtaining content data packets, performing encoding and decoding processing on the content data packets, obtaining content to be displayed, and sending the content to be displayed to the display 260 for the display 260 to display the content to be displayed. The advantage of doing this is that when the display device 200 is turned on and the user disables the network power-on function, unnecessary power consumption of the network-to-serial module 2100 can be reduced, while avoiding the situation where the content data packet cannot be received normally due to the unavailability of the first network port of the SOC 290, thereby providing protection for the content display function of the display device 200.

[0174] In some embodiments, see Figure 9, SOC 290 is connected to memory 2110. In this case, SOC 290 can also be configured to obtain the start / stop status of the network power-on function from memory 2110 in response to a standby instruction, and control the second power supply module 1802 to supply power to the network transfer string module 2100 according to the start / stop status, so as to switch the working state of the network transfer string module 2100, and control the first power supply module 1801 to stop supplying power to itself, so as to put itself into a power-off state; wherein the working state includes a power-on state and a power-off state. In the above manner, the state switching control of the network transfer string module 2100 in the standby state by SOC 290 is realized. In some specific implementations, the standby instruction may include at least one of an STR standby instruction and an AC / DC standby instruction.

[0175] Exemplarily, the SOC 290 is specifically configured to: when the start / stop status of the network power-on function stored in the memory 2110 is enabled, control the second power supply module 1802 to supply power to the network serial module 2100, so that the network serial module 2100 is in a powered-on state. When the start / stop status of the network power-on function stored in the memory 2110 is disabled, control the second power supply module 1802 to stop supplying power to the network serial module 2100, so that the network serial module 2100 is in a powered-off state, thereby avoiding unnecessary energy loss caused by the network serial module 2100 continuing to operate when the network power-on function is disabled.

[0176] The advantages of the above embodiment are that, on the one hand, SOC 290 responds to the standby command and puts itself into a power-off state, thus avoiding energy waste caused by the SOC 290 being continuously powered on in the standby state. On the other hand, when the network power-on state is enabled, the network-to-serial module is controlled to enter a power-on state to enable the network power-on function, ensuring the normal operation of the network power-on function.

[0177] Further, in some embodiments, see Figure 9 When a network switching module 2902 is provided in the display device 200, the SOC 290 can also be configured to send a first network port switching instruction to the network switching module 2902 after controlling the second power supply module 1802 to no longer supply power to the network serial module 2100; wherein the first network port switching instruction is used to instruct the network switching module 2902 to switch the currently used network port of the display device 200 to the first network port 2901.

[0178] Correspondingly, the network switching module 2902 can also be configured to obtain a first network port switching instruction, and in response to the first network port switching instruction, switch the currently used network port of the display device 200 to the first network port 2901, so that the SOC 290 can be connected to the router 500 through the first network port 2901, thereby obtaining content data packets, and encoding and decoding the content data packets to obtain the content to be displayed, and send the content to be displayed to the display 260 for the display 260 to display the content to be displayed.

[0179] It can be understood that when the network serial module is in a power-off state, the SOC sends a first network port switching instruction to the network switching module to instruct the network switching module to switch the currently used network port to the first network port, so that the SOC can obtain the content data packet when it is in a powered-on state, avoiding the situation where the SOC cannot normally receive the content data packet due to the network port not being switched.

[0180] In some other optional embodiments, the SOC 290 may be further configured to, after controlling the second power supply module 1802 to supply power to the network serial module 2100, send a second network port switching instruction to the network switching module 2902. The second network port switching instruction is used to instruct the network switching module 2902 to switch the currently used network port of the display device 200 to the second network port 21001.

[0181] Correspondingly, the network switching module 2902 can also be configured to obtain a second network port switching instruction, and in response to the second network port switching instruction, switch the currently used network port of the display device 200 to the second network port 21001 to enable the network power-on function.

[0182] It can be understood that when the network transfer serial module is in the power-on state, the SOC sends a second network port switching instruction to the network switching module to instruct the network switching module to switch the currently used network port to the second network port to enable the network power-on function, so that the network transfer serial module can receive the network power-on data packet and generate a network power-on instruction.

[0183] It is worth noting that the first network port 2901 and the second network port 21001 in the display device 200 need to have at least partially the same network configuration to ensure that after the network port switching of the display device 200 is performed, the normal use of the network function of the display device 200 (such as the conventional content display function and the network power-on function in some embodiments) is not affected.

[0184] In some embodiments, see Figure 9If the display device 200 is provided with a network switching module 2902, the network configuration information of the network switching module 2100 can be configured to be identical to the network configuration information of the display device 200, thereby ensuring that network boot commands can be properly transmitted and responded to between the network switching module 2100 and the SOC 290. The network configuration information may include at least one of an IP (Internet Protocol) address, a gateway, and a mask.

[0185] In some embodiments, see further Figure 10 A display device shown in FIG. 200 does not include a network switching module. Instead, the router 500 is connected to the first network port 2901 and the second network port 21001, respectively. To prevent the router 500 from confusing the first and second network ports 2901 and 21001 during network port switching, the first network configuration information of the second network port 21001 can be configured to be different from the first network configuration information of the first network port 2901. Furthermore, to ensure normal transmission and response of network power-up commands between the network-to-serial module 2100 and the SOC 290, the second network configuration information of the second network port 21001 is identical to the second network configuration information of the first network port 2901.

[0186] The first network configuration information may include IP address information; the second network configuration information may include other network configuration information in addition to the IP address information, for example, may include at least one of gateway information and mask information.

[0187] It is understandable that the above embodiment provides configurations for the network configuration information of the first network port and the network configuration information of the second network port in both cases where the display device is provided with a network switching module and when the display device is not provided with a network switching module, thereby increasing the richness and diversity of the display control process. Furthermore, in the case where the display device is not provided with a network switching module, the first network configuration information of the second network port is set to be different from the first network configuration information of the first network port. This can prevent the router from confusing the first network port with the second network port during the network port switching process, thereby facilitating accurate switching of the network ports.

[0188] Figure 11 is a structural diagram of a display device in some embodiments. Figure 11 The SOC 290 may be provided with a first serial port 2903, which is connected to the display 260. The network-to-serial module 2100 may be provided with a second serial port 21002, which is connected to the second network port 21001. The first serial port 2903 is connected to the second serial port 21002.

[0189] Accordingly, the SOC 290 may also be configured to monitor changes in the network of the display device 200 and, if changes occur in the network of the display device 200, synchronize the target network configuration to the second serial port via the first serial port 2903. The target network configuration information is network configuration information that the second serial port 21002 and the first serial port 2903 need to have the same configuration, such as at least one of a gateway and a mask.

[0190] In the above embodiment, by setting a first serial port 2903 in the SOC 290, setting a second serial port 21002 in the network-to-serial module 2100, and connecting the first serial port 2903 and the second serial port 21002, real-time synchronization of network configuration information between the network-to-serial module 2100 and the SOC 209 is achieved, thereby avoiding the failure of the network startup function due to different network configuration information.

[0191] Figure 12 is a structural diagram of a display device in some embodiments. Figure 12 The display device 200 is provided with an additional microcontroller unit (MCU) 2120 , and the MCU 2120 is connected to the network-to-serial module 2100 and the SOC 290 .

[0192] In some embodiments, the MCU 2120 is configured to obtain a network power-on command, generate a power-on signal in response to the network power-on command, and send the power-on signal to the SOC 290. Accordingly, the SOC 290 may also be configured to obtain the power-on signal and, in response to the power-on signal, enter a power-on state and run the operating system of the display device 200. It is worth noting that the power-on signal here is a signal that the SOC 290 can still receive or respond to in a power-off state, such as an infrared signal.

[0193] It should be noted that the display device 200 may include a basic MCU connected to the SOC 290 and the network serial module. If the basic MCU has the aforementioned additional MCU functions, the display device 200 does not need to include an additional microcontroller unit (MCU) and can directly reuse the basic MCU to implement the additional MUC functions, thereby saving hardware costs. The network serial module 2100 sends a network power-on command to its own MCU. In response to the network power-on command, the own MCU generates a power-on signal and sends the power-on signal to the SOC 290. In response to the power-on signal, the SOC 290 enters a power-on state and runs the display device's operating system.

[0194] In the above embodiment, an additional microcontroller unit (MCU) is provided to receive a network power-on command sent by the network-to-serial module 2100, generate a power-on signal in response to the network power-on command, and transmit the power-on signal to the SOC. This allows the display device to support the network power-on function by introducing an additional MCU with lower hardware cost, even when the existing MCU in the display device cannot be reused, thereby ensuring the availability of the network power-on function.

[0195] Based on the same inventive concept, in some embodiments, a display control method based on the above display device is also provided. Figure 13 As an example, the display control method provided by this embodiment is introduced. Figure 14 The display control method shown can be applied to Figure 7-13 The SOC of any display device shown in , including:

[0196] S1410: Obtain a standby instruction, and enter a standby state in response to the standby instruction.

[0197] S1420 , during the standby process, obtaining a network power-on instruction, and responding to the network power-on instruction to enter a power-on state and run an operating system of the display device.

[0198] SOC 290 obtains the user input interface 280 ( Figure 13 2901) or a standby instruction sent by the detector 230, and enters the standby state; during the standby process, obtains the network power-on instruction obtained by converting the network power-on data packet obtained by the network conversion module 2100 through its own second network port 21001; in response to the network power-on instruction, enters the power-on state, and runs the operating system of the display device 200, so that when it is in the power-on state, it can obtain the content data packet through the first network port 2901, and encode and decode the content data packet to obtain the content to be displayed.

[0199] In some embodiments, after the SOC 290 enters the power-on state in response to the basic power-on instruction, it can also obtain the start / stop status of the network power-on function from the memory 2110, and control the second power supply module 1802 to supply power to the network serial module 2100 according to the start / stop status, so as to switch the working state of the network serial module 2100; wherein the working state includes the power-on state and the power-off state.

[0200] In other optional embodiments, after the SOC 290 enters the standby state in response to the standby instruction, it can also obtain the start / stop status of the network power-on function from the memory 2110, and according to the start / stop status, control the second power supply module 1802 to supply power to the network transfer serial module 2100 to switch the working state of the network transfer serial module 2100, and control the first power supply module 1801 to no longer supply power to itself so that it enters the power-off state; wherein the working state includes the power-on state and the power-off state.

[0201] Furthermore, when the start-stop state is in the enabled state, the SOC 290 can control the second power supply module 1802 to supply power to the network-to-string module 2100, so that the network-to-string module 2100 enters the power-on state; and, when the start-stop state is in the disabled state, the SOC 290 can control the second power supply module 1802 to no longer supply power to the network-to-string module 2100, so that the network-to-string module 2100 enters the power-off state.

[0202] In some embodiments, after the SOC 290 responds to the basic power-on instruction and controls the second power supply module 1802 to power the network-to-serial module 2100 according to the start-stop status, it may also send a first network port 2901 switching instruction to the network switching module 2100 to instruct the currently used network port of the display device 200 to be switched to the first network port 2901.

[0203] In other embodiments, after the SOC 290 responds to the standby instruction and controls the second power supply module 1802 to no longer supply power to the network serial module 2100, it can also send a first network port switching instruction to the network switching module 2100 to instruct the currently used network port of the display device 200 to be switched to the first network port 2901.

[0204] In some further embodiments, after the SOC 290 responds to the standby instruction and controls the second power supply module 1802 to supply power to the network serial module 2100, it can also send a second network port switching instruction to the network switching module 2100 to instruct the currently used network port of the display device 200 to be switched to the second network port 21001.

[0205] In order to achieve network configuration synchronization between the first network port 2901 and the second network port 21001, in some optional embodiments, the SOC 290 can also monitor the network changes of the display device 200, and when the network of the display device 200 changes, synchronize the target network configuration information to the second serial port 21002 through the first serial port 2903; wherein, the target network configuration information is the network configuration information that the second network port 21001 and the first network port 2901 need to have the same configuration.

[0206] In the above embodiment, after the SOC obtains the standby instruction, it responds to the standby instruction and enters the standby state, while controlling the first power supply module to no longer supply power to itself, so that it enters the power-off state. That is to say, when the display device is in the standby state, the SOC is powered off at the same time, which can save the power consumption of the display device in the standby state, thereby extending the service life of the SOC and the display device. On the other hand, by setting a network-to-serial module in the SOC, and when the SOC is in the power-off state, the network-to-serial module is in the power-on state. When the network-to-serial module is in the power-on state, it replaces the first network port in the SOC through its own second network port to obtain a network power-on data packet, converts the network power-on data packet into a network power-on instruction, and sends the network power-on instruction to the SOC, so that the SOC responds to the power-on instruction, enters the power-on state, and runs the operating system of the display device to realize the network power-on control of the display device, ensuring that the SOC can still respond to the network power-on instruction when it is in the power-off state. In addition, compared to the prior art solution of first controlling the display device to power on, then waiting for the display device's operating system to start running, and then waking up the display device screen, the SOC in this embodiment does not need to wait for the system to run, and can immediately and quickly respond to the network power-on command, thereby reducing the response delay of the display device. On the other hand, because this embodiment uses the second network port in the network-to-serial module to replace the first network port in the SOC in the power-off state during the network wake-up process, it can directly participate in the transmission of the network power-on command. Therefore, it can overcome the problem in the prior art that the first network port of the AC-powered display device is not powered and cannot support the network power-on function, thereby improving the versatility of the network power-on function.
