[0034] It should be noted that in the embodiments of this application, "connection" can be understood as electrical connection.

For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through one or more other electrical components.

[0035] Before introducing the network architecture and display device of this application, we will first introduce the relevant background information of the embodiments of this application.

[0036] Currently, smart interactive flat panels typically include a host running Android, a PC host running Windows (OPS), a USB port, and a Type-C port. The Android host and the Windows PC host are the main devices, while the USB and Type-C ports allow connection to external devices (e.g., laptops). These main devices can each control the smart interactive flat panel's display; therefore, switching between main devices essentially means switching the display channel. If the connected main device changes from the current main device (a laptop connected via Type-C) to the target main device (a tablet connected via USB), it means the display channel changes from Type-C to HDMI. After switching the display channel, a corresponding network channel switch is required to enable the currently connected main device to connect to the internet.

[0037] In related technologies, the overall network architecture typically involves connecting a network cable to the network port of the device to access network signals. Then, the network port is connected to a switch to transmit the network signals to the switch. The switch then forwards the network signals to the host running the Android system and two PHY chips. One PHY chip is used to convert the network signals into USB signals for external devices, and the other PHY chip is used to convert the network signals into USB signals for the OPS module.

[0038] It is evident that the network architecture in the relevant technologies is quite complex, requiring a large number of chips and components, which makes layout difficult, hinders wiring, and is also detrimental to motherboard miniaturization, resulting in higher costs.

[0039] Based on this, the embodiments of this application provide a network architecture and display device. This network architecture makes full use of the interface resources of the main chip and uses the USB OTG interface of the main chip for network sharing. It enables the network channel to switch with the display channel, eliminating the need for a PHY chip for network forwarding. The structure is simple, reduces layout difficulty, reduces wiring pressure, facilitates motherboard miniaturization design, and reduces costs.

[0040] The network architecture and display device provided in this application will be described in detail below.

[0041] First, this application provides a network architecture that can be applied to display devices, such as conference screens, educational screens, and commercial screens, which are equipped with multiple display channels.

[0042] Please see Figure 1 , Figure 1 This is a schematic diagram of the first network architecture provided in this application embodiment. The display device may include a main chip 110, a network interface 120, and multiple external device interfaces. The network interface 120 can be used to access network signals. The main chip 110 may be configured with a network access interface 1101 and a USB On-The-Go (USB OTG) interface 1102. The USB OTG interface 1102 may be connected to a gating module 210. The network interface 120 may be connected to the network access interface 1101 to transmit network signals to the main chip 110. The gating module 210 may be connected to the USB OTG interface 1102 and multiple external device interfaces respectively, and is used to select the USB OTG interface 1102 and the target external device interface to forward the USB signal to the target external device 300 connected to the target external device interface. The USB signal is obtained from the network signal, and the target external device 300 is the external device currently connected to the display channel of the display device.

[0043] In this embodiment of the application, the main chip 110 of the display device can be any type of system-on-chip (SOC) running the Android system. The main chip 110 can be configured with a network access interface 1101 and a USB OTG interface 1102.

[0044] The network access interface 1101 can be connected to the network interface 120 of the display device to access network signals. Specifically, the network interface 120 can be any existing network port configured on the display device or the interface of a unit module with network function on the display device. Existing network ports include, but are not limited to, RJ45 interfaces, RJ11 interfaces, SC fiber interfaces, and Fiber Distributed Data Interface (FDDI) interfaces. Interfaces include, but are not limited to, OPS interfaces used to access OPS modules. The specific interface can be determined according to the actual application scenario and is not limited here.

[0045] The USB OTG interface 1102 is connected to the input terminal of the gating module 210 to output the USB signal obtained from the network signal to the gating module 210. The multiple output terminals of the gating module 210 are respectively connected to the multiple external device interfaces of the display device. Thus, when the gating module 210 selects the target external device interface, the USB signal can be forwarded to the target external device 300 connected to the target external device interface, so that the target external device 300 can access the network.

[0046] The selection module 210 can use any existing switch chip, including but not limited to 2-to-1, 3-to-1, and 4-to-1 switch chips, etc. The specific choice can be determined according to the actual application scenario, and is not limited here. As an example, the selection module 210 uses a USB 2.0 2-to-1 SW chip.

[0047] For example, the first output terminal of the gating module 210 is connected to the first external device interface 1301, which is connected to the first external device 310. The second output terminal of the gating module 210 is connected to the second external device interface 1302, which is connected to the second external device 320. If the target external device currently accessing the display channel is the first external device 310, then the target external device interface is the first external device interface 1301 corresponding to the first external device 310. Therefore, the gating module 210 can respond to the corresponding gating signal to select the USB OTG interface 1102 and the first external device interface 1301, thereby forwarding the USB signal to the first external device 310 so that it can access the Internet, realizing that the network channel switches with the display channel.

[0048] It is understood that in some other embodiments, the external device interface may also include more than Figure 1 The number of additional interfaces shown can be determined based on the actual application scenario, and is not limited here.

[0049] In this embodiment, by connecting the network interface 120 to the network access interface 1101 of the main chip 110 of the display device, the network signal is transmitted to the main chip 110, enabling the main chip 110 to access the network. Furthermore, the USB OTG interface 1102 of the main chip 110 is connected to multiple external device interfaces of the display device through the gating module 210. According to the switching of the display channel, the USB signal obtained from the network signal is forwarded to the corresponding target external device, enabling the target external device to access the network. Compared with the network forwarding achieved by using a switch and PHY chip in related technologies, the network architecture of this application is simple, greatly reducing the layout difficulty, reducing the wiring pressure, facilitating the miniaturization of the motherboard design, and reducing costs.

[0050] Next, continue with Figure 1 The unit modules shown are described in detail, as well as the specific implementation methods that may be used in practical applications.

[0051] like Figure 2 As shown, in some embodiments of this application, the display device is configured with a first OPS interface connected to a first OPS module (not shown in the figure), the network interface 120 is the first OPS interface, the network access interface 1101 is a USB interface, and the first OPS interface and the USB interface are connected to a first signal conversion module 220; the first signal conversion module 220 can be used to convert network signals into USB signals and output them to the USB interface.

[0052] In this embodiment, the first OPS module can be a PC running a Windows system mounted on the display device. The first OPS module itself can have a network port, allowing it to connect to a network cable and access network signals. When the first OPS interface is connected to the first OPS module, network signals from the first OPS module can be accessed. These network signals can be Media Dependent Interface (MDI) signals.

[0053] The first signal conversion module 220 can be any existing PHY chip. Its input is connected to the first OPS interface, and its output is connected to a USB interface. This allows it to convert network signals from the first OPS interface into signals for transmission to the USB interface, enabling the main chip 110 to access the network. As an example, the first signal conversion module 220 can be a USB 3.0 PHY chip.

[0054] In this embodiment, the first OPS module has a built-in network port, so the first OPS module can be directly connected to a network cable to achieve network connectivity. The first OPS interface is connected to the first OPS module, so network signals can be obtained from the first OPS module. These signals are then converted into USB signals by the first signal conversion module 220 and sent to the main chip 110, enabling the main chip 110 to connect to the network. The USB signal is forwarded to the target external device through the USBOTG interface 1102 of the main chip 110, enabling the target external device to connect to the network. The entire network architecture is simple and reliable, saving switches and some components, avoiding cable interference related to switches, reducing cabling pressure, and reducing the size of the motherboard, thus greatly reducing costs.

[0055] In some other embodiments, if the first OPS module has a built-in PHY chip, the PHY chip can convert the network signal into a USB signal inside the first OPS module. In this case, the first OPS interface is connected to the USB signal. Therefore, in this scenario, the first signal conversion module 220 can be omitted, and the first OPS interface can be directly connected to the USB interface of the main chip 110 to transmit the USB signal to the main chip and realize the main chip's network connectivity.

[0056] like Figure 3 As shown in some embodiments of this application, the first OPS interface and the first signal conversion module 220 are connected to a first hub 230; the first hub 230 can be used to enhance the network signal and transmit the enhanced network signal to the first signal conversion module 220.

[0057] In some embodiments, if the trace between the first OPS interface and the first signal conversion module 220 is long, it may cause some attenuation of the network signal during transmission. Therefore, in this embodiment, by setting a first hub 230 on the transmission link to enhance the network signal, signal attenuation caused by long traces can be avoided, and the reliability of the network signal can be ensured.

[0058] In this embodiment, the first hub 230 can be any existing USB hub, such as a USB 3.0 hub. The first hub 230 can amplify the network signal from the first OPS interface and transmit it to the first signal conversion module 220. The first signal conversion module 220 then obtains a USB signal based on the amplified network signal and transmits it to the main chip 110, thus ensuring the network stability of the main chip 110 and the target external device.

[0059] Please see Figure 4 In some embodiments of this application, the gating module 210 may also be connected to a second OPS interface 140 for accessing the second OPS module (not shown in the figure); the gating module 210 may also be used to transmit USB signals to the second OPS module when gating the USB OTG interface 1102 and the second OPS interface 140, so that the second OPS module can access the network.

[0060] In this embodiment, the second OPS module can also be a PC running a Windows system mounted on the display device. Unlike the first OPS module, the second OPS module does not have a network port. Therefore, to enable the second OPS module to connect to the network, the second OPS module can be connected to the second OPS interface 140 of the display device. When the current display channel is switched to the OPS channel, the gating module 210 responds to the corresponding gating signal to select the USB OTG interface 1102 and the second OPS interface 140, so that the USB signal can be transmitted to the second OPS module through the second OPS interface 140, enabling it to access the network.

[0061] Understandably, the selection module 210 in this embodiment can be a USB 2.0 three-to-one SW chip.

[0062] In this embodiment, the USB OTG interface 1102 of the main chip 110 is fully utilized, and the selection module 210 is used to forward the USB signal to the second OPS module, enabling the second OPS module to connect to the network, saving the PHY chip and reducing costs.

[0063] like Figure 5 As shown, in some embodiments of this application, the main chip 110 may be configured with a built-in network card, the network access interface 1101 is a built-in network card interface, and the network interface 120 is connected to the built-in network card interface through a local area network cable to transmit network signals to the built-in network card. The built-in network card is used to convert network signals into USB signals.

[0064] In this embodiment, the built-in network card can be a 10M / 100M PHY chip, and the network interface 120 can be an RJ45 network port.

[0065] The network interface 120 can connect to a network cable to access network signals. These network signals are transmitted to the built-in network card via a local area network cable, such as an 8-wire LAN cable. The built-in network card converts the accessed network signals into USB signals, which are then shared to the target external device or the second OPS module via the USB OTG interface 1102. This achieves network channel switching, simplifies the architecture, eliminates the need for a switch and its peripheral components, reduces wiring difficulty, and decreases the size of the motherboard.

[0066] like Figure 6 As shown, in some embodiments of this application, the network access interface is the physical address interface (MAC) of the main chip 110, and the network interface 120 and the physical address interface (MAC) are connected to a switch 240; the switch 240 can be used to forward network signals to the main chip 110.

[0067] In this embodiment, the main chip 110 is configured with a physical address interface (MAC). The MAC is connected to the network interface 120 through a switch 240, thereby enabling access to network signals from the network interface 120. The switch 240 can be a gigabit switch.

[0068] Specifically, network interface 120 can be connected to switch 240 via an 8-wire LAN connection, and switch 240's RGMII interface can be connected to the physical address interface (MAC) of main chip 110. After receiving network signals from network interface 120, switch 240 can transmit the MDIO signal obtained from the network signals to the physical address interface (MAC) of main chip 110 via the RGMII interface, thereby enabling main chip 110 to access the network.

[0069] like Figure 7 As shown, in some embodiments of this application, the switch 240 and the second OPS interface 140 may be connected to a second signal conversion module 250; the second signal conversion module 250 may be used to convert network signals into USB network signals and output them to the second OPS module.

[0070] In this embodiment, the second signal conversion module 250 can be any existing PHY chip. One end of the second signal conversion module 250 is connected to the switch 240, and the other end is connected to the second OPS interface 140, thereby converting the network signal from the switch 240 into a USB network signal and transmitting it to the second OPS interface 140, enabling the second OPS module connected to the second OPS interface 140 to access the network. As an example, the second signal conversion module 250 can be a USB 3.0 PHY chip.

[0071] In this embodiment, the network can be forwarded to the second OPS module via the USB OTG interface 1102, or via the switch 240 in conjunction with the second signal conversion module 250. When a network channel fails, another network channel can be selected to enable the second OPS module to connect to the network, thereby improving the reliability of the network architecture.

[0072] like Figure 8 As shown, in some embodiments of this application, the second signal conversion module 250 and the second OPS interface 140 may be connected to a second hub 260; the second hub 260 may be used to enhance the USB network signal and transmit the enhanced USB network signal to the second OPS module.

[0073] Similarly, if the trace between the second OPS interface 140 and the second signal conversion module 250 is long, it may cause some attenuation of the USB network signal during transmission. Therefore, in this embodiment, by setting a second hub 260 on the transmission link to enhance the USB network signal, the signal attenuation caused by the long trace can be avoided, and the reliability of the USB network signal can be ensured.

[0074] In this embodiment, the second hub 260 can be any existing USB hub, such as a USB 3.0 hub. The second hub 260 can amplify the USB network signal from the second signal conversion module 250 and transmit it to the second OPS interface 140, ensuring the network stability of the second OPS module connected to the second OPS interface 140.

[0075] like Figure 9 As shown, in some embodiments of this application, the USB OTG interface 1102 and the gating module 210 may be connected to a third hub 270; the third hub 270 may be used to enhance the USB signal and transmit the enhanced USB signal to the gating module 210.

[0076] Similarly, in order to ensure the strength of the USB signal transmitted from the USB OTG interface 1102 to the gating module 210, in this embodiment of the application, a third hub 270 may also be provided on the transmission link from the USB OTG interface 1102 to the gating module 210.

[0077] The third hub 270 can be any existing USB hub, such as a USB 2.0 hub. The third hub 270 can amplify the USB signal from the USB OTG interface 1102 and transmit it to the gating module 210. Thus, when the gating module 210 selects a target external device, it can forward the USB signal to the target external device, ensuring the network stability of the target external device.

[0078] Based on the above embodiments, this application also provides a display device, which may include a main chip, a network interface, multiple external device interfaces, and such as... Figures 1 to 9 The network architecture corresponding to any embodiment.

[0079] The display device can be a smart interactive flat panel such as a conference screen, an educational screen, or a commercial screen.
