Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and in particular relates to a TYPE-C interface control component, a control method, and a display device. Background Art

[0002] Interactive display devices, such as LED (Light-Emitting Diode) screens and all-in-one conference machines, are highly integrated display systems capable of displaying content through a variety of interfaces, such as HDMI (High-Definition Multimedia Interface), USB (Universal Serial Bus), and network interfaces, connecting to external computers, mobile phones, projectors, and removable storage devices. These devices not only support basic display functions but also offer user interaction capabilities, allowing users to interact directly with the SOC (System on a Chip) interface through a touch screen or other input methods, and control built-in OPS (Open Pluggable Specification) devices.

[0003] Although existing interactive display devices have integrated a wealth of functions, they still have certain limitations in achieving reverse control. Specifically, current interactive display devices can only achieve one-way data transmission and control from external devices to the display device. This allows external devices (such as computers, mobile phones, and tablets) to transfer content to the interactive display device for display. However, users cannot directly control these external devices through the touch screen or other input methods of the interactive display device. For example, users cannot use the touch screen to control applications on their mobile phone or tablet, switch screen content, or perform other operations.

[0004] Therefore, existing interactive display devices can only achieve one-way transmission but cannot achieve reverse control. This limitation makes user operations extremely cumbersome in scenarios where multiple devices work together. Summary of the Invention

[0005] In view of this, the embodiments of the present application provide a TYPE-C interface control component, a control method and a display device, which can realize reverse control of the interactive display device on the external device while realizing one-way transmission, thereby improving the flexibility of the interactive display device and simplifying the user's operation.

[0050] In the application, the interactive module 30 has user interaction capabilities, allowing users to directly interact with the SOC end interface through touch or other input methods and control the built-in OPS devices. The interactive module 30 can be an infrared frame set around the display screen, such as Figure 2 As shown, the infrared bezel can be connected via a touch interface (i.e., a touch screen interface or touch panel interface), which uses a USB 4-pin socket 70 or an OPS USB interface 80. The four pins in the USB 4-pin socket are the power line (VBus) that provides 5V DC power, the negative data line (D-) and the positive data line (D+) for data transmission, and the ground line (GND) that provides a common reference point. The OPS USB interface is a USB interface used in OPS (Open Pluggable Specification) modules.

The OPS USB interface follows the standard USB protocol and typically includes a power line (VBus), a negative data line (D-), a positive data line (D+), and a ground line (GND) to enable data transmission and device power.

This increases the flexibility of interactive display devices and simplifies user operation. Furthermore, the Type-C interface module transmits both USB and video signals, offering a high level of integration and reducing the number of interfaces, thus lowering costs and simplifying wiring.

[0052] In one embodiment, the USB switching module 40 is further configured to transmit the control signal output by the interaction module 30 to the main control module 20 based on the channel selection signal.

[0053] In application, the USB switching module 40 can enable the control instructions of the interactive module 30 to act on the main control module 20 to achieve control of the display device itself, such as selecting an application, switching screen content, or performing other operations.

[0054] The USB switching module 40 of the embodiment of the present application is also used to transmit the control signal output by the interactive module 30 to the main control module 20 based on the channel selection signal, so that the user can control the display device accordingly through the interactive module, thereby realizing the interactive function of the display device.

[0055] In one embodiment, Figure 2 As shown, the USB switching module 40 includes a first USB switch 401, a second USB switch 402 and a third USB switch 403;

[0056] The controlled end of the first USB switch 401 is connected to the first control end of the main control module 20, the input end of the first USB switch 401 is connected to the first output end of the second USB switch 402, and the output end of the first USB switch 401 is connected to the first data end of the main control module 20;

[0057] The controlled end of the second USB switch 402 is connected to the second control end of the main control module 20, the input end of the second USB switch 402 is connected to the output end of the interactive module 30, the second output end of the second USB switch 402 is connected to the first input end of the third USB switch 403, and the first output end of the third USB switch 403 is connected to the USB interface of the TYPE-C interface module;

[0059] In use, when the first control terminal of the main control module 20 sends a first enable signal (EN1 signal) to the first USB switch 401, the first USB switch 401 establishes a connection between the USB HUB2 and the first output terminal of the second USB switch 402. The control signal output by the interactive module 30 is transmitted to the first data terminal of the main control module 20 through the second USB switch 402, the USB HUB2, and the first USB switch 401, thereby controlling the display device. When the second control terminal of the main control module 20 sends a second enable signal (EN2 signal) to the second USB switch 402, the second USB switch 402 establishes a connection between the output terminal of the interactive module 30 and the first input terminal of the third USB switch 403.

When the third control terminal of the main control module 20 sends a third enable signal (EN3 signal) to the third USB switch 403, the third USB switch 403 establishes a connection between the USB interface 101 of the TYPE-C interface module 10 and the USB HUB 1, thereby achieving a connection between the USB interface 101 of the TYPE-C interface module 10 and the second data terminal of the main control module 20 through the USB HUB 1. The data signal transmitted by the external device through the USB interface 101 of the TYPE-C interface module 10 passes through the second input terminal of the third USB switch 403, and then is transmitted to the USB HUB 1 through the second output terminal of the third USB switch 403, reaching the second data terminal of the main control module 20, thereby achieving data transmission from the external device to the display device.

The flexible switching and management of the three USB switches under different control signals can effectively process data streams from different sources, ensuring that data can be correctly transmitted from external devices (such as mobile phones, tablets) or interactive modules to the main control module 20, and also supports data transmission from the interactive module to external devices. This bidirectional data transmission mechanism not only enhances the interactivity and responsiveness of the system, but also allows users to directly control applications on external devices through a touch screen or other input methods, realizing data transmission and control of the display device by the external device, and also allows the interactive display device to reversely control the external device, such as adjusting settings, launching applications, or switching screen content. This design greatly improves the user experience, especially in scenarios where multiple devices work together, such as education, meetings, and presentations. It provides users with a more intuitive and efficient operating environment, making information sharing and collaboration more seamless and natural.

[0061] In one embodiment, a USB hub is provided, specifically including a first USB hub 50 (i.e., USB HUB1) and a second USB hub 60 (i.e., USB HUB2). The input terminal of the first USB switch 401 is connected to the first output terminal of the second USB switch 402 via USB HUB2, and the output terminal of the third USB switch 403 is connected to the second data terminal of the main control module 20 via USB HUB1.

[0062] By introducing a first USB hub between the output of the third USB switch and the second data port of the main control module, and adding a second USB hub between the input of the first USB switch and the first output of the second USB switch, the embodiment of the present application not only increases the system's ability to connect to external devices but also improves the flexibility and efficiency of interface usage. This configuration allows the main control module to access multiple peripherals connected via the USB hub simultaneously or on demand without adding additional physical USB ports, thereby optimizing resource utilization and providing expansion space for the potential need to connect more devices in the future. Furthermore, this structure helps simplify circuit layout and facilitates management and maintenance.

[0063] In one embodiment, two USB ports are further expanded on the main control board 2. By expanding the two USB ports on the main control board 2, multiple external data sources can be input and / or output to the display device.

[0064] In one embodiment, the main control module 20 includes a channel switching module, and the channel switching module includes a first channel switching module, a second channel switching module, and a third channel switching module;

[0065] The channel switching module is used to determine the operating mode of the display device and send a channel selection signal to the USB switching module based on the operating mode;

[0066] The first channel switching module is used to determine that the display device is in the first working mode when the TYPE-C interface module is connected to an external device and the external device is not used as a controlled object, and to send an enable signal to the first USB switch 401 and the second USB switch 402;

[0067] The second channel switching module is used to determine that the display device is in the second working mode when the TYPE-C interface module is connected to an external device and the external device is used as a controlled object, and to send an enable signal to the second USB switch 402 and the third USB switch 403;

[0068] The third channel switching module is used to determine that the display device is in the third working mode when the TYPE-C interface module is not connected to an external device, and to send an enable signal to the third USB switch 403.

[0069] In application, when the TYPE-C interface module 10 is connected to an external device and the external device is not used as a controlled object, it is determined that the display device is in the first working mode. In this mode, the external device mainly serves as a data source or content provider. For example, a user can connect a mobile phone or tablet to the display device, and the TYPE-C input source status of the display device is detected as having successfully connected to an external device (such as a mobile phone or tablet). The detection status can be distinguished by different colors on the display screen, such as green for connected and gray for unconnected, or by different identifiers, such as √ for connected and × for unconnected. When the user operation interface does not enter the external source, that is, the TYPE-C source is not used as a controlled object, the system software running in the main control module will control the GPIO (General Purpose Input / Output) pin to switch the second USB switch so that it is established with the USB HUB2 channel. The system software will also switch the first USB switch through the GPIO pin to establish a connection with the first data terminal of the main control module. Through this connection, the touch operation of the internal SOC interface is realized.

[0070] In application, when the TYPE-C interface module 10 is connected to an external device and the external device is used as a controlled object, it is determined that the display device is in the second working mode. In this mode, the display device can not only receive data and content from the external device, but also reversely control the external device through an interactive module, such as a touch border or other input methods. When the TYPE-C input source status of the display device is detected as having successfully connected to the external device, and when the user enters the TYPE-C source (i.e., the TYPE-C source is used as a controlled object) through the remote control operation interface or other methods, the display device will automatically switch to the corresponding input source and be ready for two-way communication. The system software running in the main control module will control the GPIO pin to enable and switch the third USB switch so that the USB channel in TYPE-C is connected to the second USB switch. At the same time, the system software will also control the GPIO pin to switch the second USB switch so that it is connected to the USB Touch interface and establish a touch control channel. Through the above-mentioned USB channel switching, the infrared border on the display device can achieve reverse control of the external device. The user can directly control the application, adjust settings, browse files, etc. on the external device through the touch screen. This reverse control feature significantly enhances the user experience, allowing users to more intuitively and conveniently operate small-screen devices on the large screen. For example, in educational settings, teachers can use the touchscreen to display and control content on students' tablets on the large screen; in conference settings, presenters can directly operate presentations on their phones or tablets on the large screen.

[0071] In use, when the Type-C interface module 10 is not connected to an external device, the display device is determined to be in the third operating mode. In this mode, the display device operates independently, relying on the built-in operating system and resources. The GPIO pins in the main control module toggle the third USB switch, selecting the USB channel in the Type-C interface module to establish connectivity with USB HUB1, thus implementing universal USB functionality.

[0072] In an application, when it is determined that the display device is in the first operating mode, an enable signal is sent to the first USB switch 401 and the second USB switch 402. Assuming that the control pin of the first USB switch 401 is SW1_SE, when SW1_SE is set to the L level, the first USB switch 401 will establish a connection between the USB HUB2 and the main control module, so that data can be transmitted from the USB HUB2 to the first data terminal of the main control module 20. When SW1_SE is set to the H level, the first USB switch 401 can switch to other channels or disconnect. Assuming that the control pin of the second USB switch 402 is SW2_SE, when SW2_SE is set to the L level, the second USB switch 402 will establish a connection between the interactive module 30 and the USB HUB2. When SW2_SE is set to the H level, the second USB switch 402 can switch to other channels or disconnect.

[0073] In an application, when it is determined that the display device is in the second operating mode, an enable signal is sent to the second USB switch 402 and the third USB switch 403. Assuming that the control pin of the second USB switch 402 is SW2_SE, when SW2_SE is set to an H level, the second USB switch 402 will establish a connection between the interaction module 30 and the third USB switch 403. Assuming that the control pin of the third USB switch 403 is SW3_SE, when SW3_SE is set to an L level, the third USB switch 403 will establish a connection between the second USB switch 402 and the USB interface of the TYPE-C interface module 10, achieving reverse control.

[0074] In application, when it is determined that the display device is in the third operating mode, an enable signal is sent to the third USB switch 403. Assuming that the control pin of the third USB switch 403 is SW3_SE, when SW3_SE is set to the H level, the third USB switch 403 will establish a connection between the USB interface of the TYPE-C interface module 10 and the USB HUB1.

[0075] The embodiment of the present application includes a channel switching module, which includes a first channel switching module, a second channel switching module and a third channel switching module; the channel switching module is used to determine the working mode of the display device, and based on the working mode, send a channel selection signal to the USB switching module; the first channel switching module is used to determine that the display device is in the first working mode when the TYPE-C interface module is connected to an external device and the external device is not used as a controlled object, and send an enable signal to the first USB switch 401 and the second USB switch 402; the second channel switching module is used to determine that the display device is in the second working mode when the TYPE-C interface module is connected to an external device and the external device is used as a controlled object, and send an enable signal to the second USB switch 402 and the third USB switch 403; the third channel switching module is used to determine that the display device is in the third working mode when the TYPE-C interface module is not connected to an external device, and send an enable signal to the third USB switch 403. The main control module 20 dynamically determines the operating mode of the display device based on the connection status of the TYPE-C interface module 10 and the role of the external device. This not only provides a high degree of flexibility and adaptability, allowing the device to switch seamlessly in a variety of application scenarios, but also significantly enhances the user experience. In particular, reverse control of external devices is achieved in the second operating mode, allowing users to operate small-screen devices more intuitively and conveniently on the large screen, improving operational efficiency and interactivity. At the same time, this method of controlling the USB switch through GPIO pins ensures the correct transmission of data streams, achieving flexible switching and efficient communication in different operating modes. By precisely controlling the status of each USB switch, the system can automatically configure hardware connections, simplify the user's operating process, and improve system reliability and performance.

[0076] In one embodiment, Figure 3 and 4 As shown, the main control module 20 and the USB switching module 40 are arranged on the main control board 2 of the display device, the TYPE-C interface module 10 is arranged on the front board 1 of the display device, and the front board 1 and the main control board 2 are connected through a connection. The front board 1 and the main control board 2 are arranged on the display screen of the display device, or are arranged in the playback control box 300 of the display device.

[0077] In use, when the front-end board 1 and the main control board 2 are installed on the display screen 200 of a display device, the external device 100 is connected to the display device via the Type-C port 103 on the front-end board 1. The front-end board 1 is connected to the main control board 2 via the USB port 101 and the video port 102 of the Type-C interface module 10. The interactive module 30 is an infrared bezel integrated into the edge of the display screen 200 and connected to the main control board 2 via USB. The main control board 2 processes the signal, such as decoding, scaling, and color correction, to ensure that the video content is displayed accurately on the LED screen. The processed data is converted into a format suitable for the LED display and sent to the sending card 3 via the HDMI 2.0 OUT port. The sending card 3 receives the processed data stream from the main control board and further processes it, including segmenting the image data for distribution to multiple receiving cards 4. The receiving cards 4 receive their respective portions of the image data from the sending card 3 and, based on the received data, indicate whether the corresponding LED beads are emitting light, as well as parameters such as brightness and color, to form the final visible image segment.

[0078] In application, when the front board 1 and the main control board 2 are set in the playback control box 300 of the display device, the external device 100 is connected to the playback control box 300 through the TYPE-C interface 103 on the front board 1, and the video signal of the external device 100 (such as a computer, player, etc.) is sent to the display screen 200 through the network (usually Ethernet or optical fiber) through the network port daughter board 301. Finally, the receiving card 4 obtains its own part of the image data, and instructs the corresponding LED lamp beads whether to emit light and the brightness, color and other parameters according to the received data, thereby forming the final visible picture segment.

[0079] In use, when the front-end board 1 and main control board 2 are installed on the display screen of the display device, they are placed in the lower right corner and behind the LED display, respectively. The front-end board 1 is placed in the lower right corner of the LED display, making it easy for users to connect external devices; the main control board 2 is placed behind the display to maintain a clean appearance and provide ample space for complex circuitry. This layout makes the entire system more compact, reduces extra cable length, and minimizes interference during signal transmission. The front-end board 1 is located in the lower right corner of the display screen, making it easy for users to quickly connect and disconnect external devices, while the main control board 2 is located behind the display screen for easy maintenance and upgrades by technicians. All key components are integrated within the display screen, improving system integrity and stability. When the front-end board 1 and main control board 2 are installed in the display device's playback control box, the playback control box is separated from the display screen and connected to the screen via a Type-C cable or Ethernet cable. The playback control box can be placed in any convenient location, regardless of the display screen's mounting position, making it suitable for a variety of installation environments. Placing the main control module and front-end card in a separate broadcast control box allows for better heat management and extends device life. Hardware upgrades require replacing components within the control box without disassembling the entire display, simplifying the upgrade process. Separating the control circuitry from the display circuitry reduces electromagnetic interference and improves system stability and reliability.

[0080] In the embodiment of the present application, the main control module 20 and the USB switching module 40 are arranged on the main control board 2 of the display device, the TYPE-C interface module 10 is arranged on the front board 1 of the display device, and the front board 1 and the main control board 2 are connected via a connection. The front board 1 and the main control board 2 are arranged on the display screen of the display device, or are arranged in the playback control box of the display device. This flexible hardware layout design not only improves the adaptability and maintainability of the system, but also optimizes heat dissipation management and electromagnetic compatibility, so that the display device can perform well in a variety of application scenarios. Whether it is education, conferences, commercial displays or remote collaboration, this design can provide efficient, reliable and convenient solutions.
