[0041] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0042] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0043] It is understandable that before using the technical solutions of each embodiment of the present application, the type, scope of use, usage scenarios, etc. of the personal information involved will be informed to the user in an appropriate manner, and the user's authorization will be obtained.

[0044] For example, in response to receiving an active request from a user, a prompt message is sent to the user to clearly remind the user that the operation requested to be performed will require obtaining and using the user's personal information. Thus, the user can independently choose whether to provide personal information to the electronic device, application, server, storage medium or other software or hardware that performs the operation of the technical solution of the present application according to the prompt message.

[0045] As an optional but non-limiting implementation, in response to receiving the user's active request, the prompt information may be sent to the user in the form of a pop-up window, in which the prompt information may be presented in text form. In addition, the pop-up window may also carry a selection control for the user to choose "agree" or "disagree" to provide personal information to the electronic device.

[0046] It is understandable that the above notification and the process of obtaining user authorization are merely illustrative and do not constitute a limitation on the implementation method of this application. Other methods that meet relevant laws and regulations may also be applied to the implementation method of this application.

[0047] The interface is a channel for data transmission, supporting data exchange between the display device and external devices, such as the transmission of video, audio files and other materials, as well as the synchronous update of real-time data.

[0048] At present, conference tablets, all-in-one conference machines and other products have become the preferred equipment in conference rooms. All-in-one conference machines and other products generally have front panels. Due to different user needs, the front panel interfaces are diverse, for example, High Definition Multimedia Interface (HDMI), DisplayPort (DP), Universal Serial Bus Interface (TYPEC), etc., with many types and quantity requirements.

[0049] In particular, it is also necessary to link the open pluggable specification (OPS) interface and the front panel interface. The video input interface of the system on chip (SOC) is not enough. In order to adapt to various front panel requirements, additional conversion chips need to be added. For example, it is generally necessary to add video switching chips and video conversion chips, such as IT66353, PS176, GSV2712, etc.; the OPS interface is generally an HDMI interface, and only a fixed HDMI input is required, but the requirements of different products for the front panel or different users for the front panel video interface are different, mainly three categories, HDMI, DP and TYPEC. The current mainstream solution is to design different front panels, add conversion video chips on the front panels, convert them into HDMI signals and then connect them to the mainboard. This solution is bound to increase costs, and each product needs to develop software separately for adaptation, which increases material costs and development costs; in addition, if the product does not have the interface required by the user, such as only an HDMI interface on the product, and the user-end interface is DP or TYPEC, the signal can only be converted into HDMI through an adapter cable or an adapter board, and this solution is costly.

[0050] Figure 1 The data input control system of the display device according to the embodiment of the present application is shown, and the system includes a mainboard module 120 and a video signal compatible circuit 110 arranged in the front panel;

[0051] The video signal compatible circuit 110 is configured to receive a media resource signal transmitted by a user device, generate a voltage division signal based on the media resource signal, and transmit the voltage division signal to the mainboard module 120;

[0052] The mainboard module 120 is configured to determine the current interface type corresponding to the media resource signal according to the voltage division signal, obtain the stored historical interface type, determine the target driver based on the historical interface type and the current interface type, and select a target signal processing path from multiple preset signal paths based on the current interface type, and use the target driver to control the target signal processing path to convert the media resource signal to a preset signal type so that the display device can display the media resource signal according to the preset signal type.

[0053] In specific implementation, the data input control system of the display device is mainly composed of two key parts: a mainboard module 120 and a video signal compatible circuit 110 arranged in the front panel.

[0054] The video signal compatible circuit 110 is arranged in the front panel of the display device. Its main function is to receive media resource signals transmitted from user equipment, which refers to any device capable of generating video or audio signals, such as computers, game consoles, digital versatile disc (DVD) players, etc. The media resource signals may include video and audio data.

[0055] The video signal compatibility circuit 110 generates a corresponding voltage-divided signal based on a media resource signal transmitted from a user device of a corresponding interface type, and the voltage-divided signal is then transmitted to the mainboard module 120 for further processing and analysis.

[0056] The mainboard module 120 can determine the current interface type corresponding to the media resource signal according to the voltage division signal. The interface type may include High Definition Multimedia Interface (HDMI), Universal Serial Bus Interface (TYPEC), Video Graphic Array Interface (VGA), Digital Visual Interface (DVI), DisplayPort (DP), etc.

[0057] The mainboard module 120 also stores information about historical interface types, which helps the system understand the interface types previously used by the user, can be used to optimize the modification of the driver, and provide a user-friendly interface switching experience.

[0058] Based on the current interface type and the historical interface type, the mainboard module 120 can determine a target driver that is necessary for processing the current interface type signal to ensure that the signal can be correctly decoded and displayed.

[0059] The mainboard module 120 selects a target signal processing path from a plurality of preset signal paths, which correspond to different interface types or signal processing methods.

[0060] The target signal processing path is driven by the selected target driver to convert the media resource signal into a preset signal type. The preset signal type is a standard signal format that can be recognized and processed by the display device, such as a high-definition multimedia interface.

[0061] Finally, the converted media resource signal is sent to the display unit of the display device for viewing by the user.

[0062] The data input control system of the present application realizes compatibility, identification, processing and conversion of media resource signals transmitted by user equipment through the coordinated work of the video signal compatibility circuit 110 and the mainboard module 120, ensuring that the display device can correctly display media resources from different interface types.

[0063] Through the above scheme, the interface compatibility of the display device is greatly expanded through the video signal compatible circuit 110 in the front panel. The media resource signal transmitted by the user device can be recognized and processed by the system regardless of its original interface type. The mainboard module 120 intelligently determines the current interface type based on the received voltage divider signal, and compares it with the stored historical interface type to select the most appropriate driver and signal processing path. This design not only solves the problem of the single interface of the existing display device, but also provides users with more interface options, meeting the diversified connection requirements between different users and different devices. In addition, the system can automatically convert the media resource signal to the preset signal type, ensuring that the display device can display content smoothly and with high quality, thereby improving the user experience.

[0064] In some embodiments, Figure 2 As shown, the video signal compatible circuit 110 includes: a first interface unit 111 and a second interface unit 112;

[0065] The first interface unit 111 is configured to receive a media resource signal transmitted by a user equipment, generate a divided pressure signal based on the media resource signal, and transmit the divided pressure signal to the second interface unit 112;

[0066] The second interface unit 112 is configured to transmit the divided voltage signal to the mainboard module 120 .

[0067] In a specific implementation, the first interface unit 111 receives a media resource signal from a user device. Once the media resource signal is received, the first interface unit 111 generates a voltage division signal based on the signal. Voltage division usually means that the signal is adjusted or converted to meet the requirements of subsequent circuits or devices. This may be for purposes such as matching voltage levels, impedance matching, signal format conversion, etc.

[0068] After generating the divided voltage signal, the first interface unit 111 transmits it to the second interface unit 112. This process ensures that the signal can be seamlessly transferred from one interface unit to another in preparation for further processing or transmission.

[0069] The second interface unit 112 is mainly used to transmit the voltage division signal received from the first interface unit 111 to the mainboard module 120. The mainboard module 120 is a core component in the electronic device, responsible for processing various signals and data, and controlling the overall operation of the device.

[0070] The process of transmitting the signal to the mainboard module 120 ensures that the video or audio signal can be correctly received and processed by the mainboard module 120. The relevant circuits or components on the mainboard module will decode, amplify or further process these signals and finally output them to output devices such as display screens and speakers.

[0071] In summary, the video signal compatibility circuit 110 receives media resource signals from user devices through the cooperation of the first interface unit 111 and the second interface unit 112, and transmits these signals safely and effectively to the mainboard module 120 for processing through appropriate signal adjustment (voltage division). Such a design helps to ensure compatibility between different user devices, while optimizing signal quality to meet the output requirements of the device.

[0072] In some embodiments, Figure 3 As shown, the first interface unit 111 includes: a first connection subunit 1111 and a second connection subunit 1112;

[0073] The first connection subunit 1111 is configured to receive a media resource signal transmitted by a user equipment, determine a signal type of the media resource signal, select a target transmission path from a plurality of preset signal transmission paths based on the signal type, and transmit the media resource signal to the second connection subunit 1112 using the target transmission path;

[0074] The second connecting subunit 1112 is configured to determine a resistor with a resistance value corresponding to the signal type, generate a voltage-divided signal through a preset first supply voltage and a resistor with a resistance value corresponding to the signal type, and transmit the voltage-divided signal to the second interface unit 1112 .

[0075] In a specific implementation, the first connection subunit 1111 receives media resource signals from the user equipment, which may include audio, video, image or other forms of multimedia content.

[0076] Once a signal is received, the first connection subunit 1111 analyzes and determines the type of the signal to ensure that subsequent signal processing and transmission can be optimized according to the specific type of the signal, wherein the signal type may be an interactive signal, a differential signal or a detection signal.

[0077] Based on the determined signal type, the first connection subunit 1111 selects a most suitable path from a plurality of preset signal transmission paths, which may involve selecting different lines, channels or transmission protocols to ensure that the signal can be transmitted efficiently and accurately.

[0078] After selecting the target transmission path, the first connection subunit 1111 transmits the media resource signal to the second connection subunit 1112, preparing for the next step of processing.

[0079] The second connecting subunit 1112 generates a voltage division signal using a resistor with a corresponding fixed resistance value according to the type of the signal received from the first connecting subunit 1111 .

[0080] For example, if the interface on the front panel is TYPEC, then the pull-down resistor on the front panel is fixed at 6.2K, which can be detected as soon as the mainboard is powered on;

[0081] If the other front panel interface is HDMI, then you need to replace it with a front panel with an HDMI interface. The pull-down resistor on the front panel with an HDMI interface is 0R.

[0082] Alternatively, the adapter board is similar. The external user device interface on the whole machine is an HDMI interface. If the user wants to use the HDMI interface, directly connect it with an HDMI cable;

[0083] If you want to use the TYPEC interface, you need to plug a TYPEC to HDMI adapter board into the whole machine. There is a fixed pull-down resistor of 6.2K on this TYPEC to HDMI adapter board. As long as this adapter board is connected, the motherboard can identify what type of signal is connected by detecting the pull-down resistor;

[0084] The corresponding resistance value is determined according to different adapter boards and interface boards.

[0085] Finally, the second connection subunit 1112 transmits the generated voltage division signal to the second interface unit 112, so as to determine the current interface type by using the voltage division signal.

[0086] In some embodiments, the signal type in response to the media resource signal is a differential data signal, and the current interface type corresponding to the media resource signal is a high-definition multimedia interface, and the first positive data pin, the second positive data pin, the third positive data pin, the fourth positive data pin, the first negative data pin, the second negative data pin, the third negative data pin, and the fourth negative data pin of the first connecting subunit 1111 are all connected in series with a resistor with a preset first resistance value.

[0087] In specific implementation, differential data signaling is a signal transmission method that uses two complementary signal paths to transmit data. The signals on these two paths are equal in amplitude but opposite in polarity, and the receiving end recovers the original data by comparing the difference between the two signals. This method can reduce electromagnetic interference (EMI) and radio frequency interference (RFI), and improve the reliability and accuracy of signal transmission.

[0088] If the media resource signal is transmitted in the form of a differential data signal, and the current interface type corresponding to the media resource signal is a High Definition Multimedia Interface (HDMI).

[0089] Each positive data pin and the corresponding negative data pin of the first connection subunit 1111 are connected in series with a resistor of a preset first resistance value. This connection method may be to match the impedance of the transmission line, reduce signal reflection, and help ensure stable and high-quality transmission of high-definition video and audio signals between devices. The series resistance value is usually determined according to the HDMI specification and the characteristic impedance of the transmission line to ensure the best signal transmission performance.

[0090] For example, Figure 4 As shown, HDMI is generally DC coupled, and a resistor with a preset first resistance value is connected in series or directly connected through the first positive data pin (VI_D0P), the second positive data pin (VI_D1P), the third positive data pin (VI_D2P), the fourth positive data pin (VI_D3P), the first negative data pin (VI_D0N), the second negative data pin (VI_D1N), the third negative data pin (VI_D2N), and the fourth negative data pin (VI_D3N) of the first connecting subunit 1111.

[0091] DP and TYPEC are AC coupled, and capacitors need to be connected in series through the first positive data pin (VI_D0P), the second positive data pin (VI_D1P), the third positive data pin (VI_D2P), the fourth positive data pin (VI_D3P), the first negative data pin (VI_D0N), the second negative data pin (VI_D1N), the third negative data pin (VI_D2N), and the fourth negative data pin (VI_D3N) of the first connecting subunit 1111. The differential data signal on the mainboard is directly connected to the corresponding pin of the receiving channel B port (RXB port) of the video conversion chip (GSV2712) in the mainboard module 120, and a resistor or capacitor is selected in series on the front panel according to the interface type.

[0092] In some embodiments, the signal type in response to the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a high-definition multimedia interface, the serial data line pin of the first connecting subunit 1111 is connected in series with the first resistor and the second resistor, and the serial clock line pin of the first connecting subunit 1111 is connected in series with the third resistor and the fourth resistor.

[0093] In a specific implementation, if the signal type of the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a high definition multimedia interface (HDMI), the serial data line pin of the first connecting subunit 1111 is connected in series with the first resistor and the second resistor, and the serial clock line pin thereof is connected in series with the third resistor and the fourth resistor to meet the signal transmission requirement.

[0094] Among them, the interactive signal is used for communication and status confirmation between devices.

[0095] For example, Figure 5 As shown, HDMI is a display data channel (DisplayDataChannel, DDC) (serial data line SDA / serial clock line SCL) signal, which needs to be pulled up 47K to 5V and connected to the chip resistor.

[0096] That is, if the signal type of the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a High Definition Multimedia Interface (HDMI), then the serial data line pin (SDA / AUXP / SBU1) of the first connection subunit 1111 is connected in series with the first resistor (R799) and the second resistor (R797), and the serial clock line pin (SCL / AUXN / SBU2) thereof is connected in series with the third resistor (R798) and the fourth resistor (R796).

[0097] In some embodiments, the signal type in response to the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a display interface, the serial data line pin of the first connecting subunit 1111 is connected in series with the first capacitor and the fifth resistor, and the serial clock line pin of the first connecting subunit 1111 is connected in series with the second capacitor and the sixth resistor.

[0098] In a specific implementation, if the signal type of the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a display interface (DisplayPort, DP), wherein the display interface is generally used to output visual content such as video and images to a display device (such as a screen, a display). Then the serial data line pin of the first connection subunit 1111 is connected in series with the first capacitor and the fifth resistor, and this connection method can be used for signal conditioning, filtering or impedance matching to ensure stable data transmission, and the serial clock line pin of the first connection subunit 1111 is connected in series with the second capacitor and the sixth resistor.

[0099] Among them, capacitors can be used for filtering, isolating DC signals, decoupling or energy storage. In serial communications, capacitors can help smooth signals and reduce noise interference.

[0100] Resistors are used in circuits to limit current, divide voltage, or act as loads. In serial communication lines, resistors can be used to match line impedance, reduce signal reflections, and improve signal quality.

[0101] For example, Figure 6 As shown, DP is the differential signal of the bidirectional transmission auxiliary channel (Auxiliary, AUX). The positive pole (AUXP) of the bidirectional transmission auxiliary channel is pulled up by 1M to 3.3V, and the negative pole (AUXN) of the bidirectional transmission auxiliary channel is pulled down by 1M to GND, and a capacitor needs to be connected in series to isolate the DC signal.

[0102] That is, if the signal type of the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a display interface (DisplayPort, DP), the serial data line pin (SDA / AUXP / SBU1) of the first connecting sub-unit 1111 is connected in series with the first capacitor (C271) and the fifth resistor (R413). This connection method can be used for signal conditioning, filtering or impedance matching to ensure stable data transmission, and the serial clock line pin (SCL / AUXN / SBU2) of the first connecting sub-unit 1111 is connected in series with the second capacitor (C272) and the sixth resistor (R423).

[0103] In some embodiments, the signal type in response to the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a universal serial bus interface, the serial data line pin of the first connecting subunit 1111 is connected in series with the third capacitor, and the serial clock line pin of the first connecting subunit 1111 is connected in series with the fourth capacitor.

[0104] In specific implementation, if the signal type of the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a universal serial bus interface (TYPEC), the serial data line pin of the first connecting subunit 1111 is connected in series with the third capacitor, and the serial clock line pin of the first connecting subunit 1111 is connected in series with the fourth capacitor.

[0105] Among them, the universal serial bus interface (TYPEC) is used to connect the display device with external user equipment (such as printers, scanners, keyboards, mice, storage devices, etc.). Here, it is mentioned that the media resource signal is transmitted through the universal serial bus interface (TYPEC), indicating that this connection supports serial transmission of data and complies with the universal serial bus standard.

[0106] The serial data line pin of the first connection subunit 1111 and the series connection of the third capacitor can be used for filtering, smoothing signals, suppressing noise or performing signal conditioning to ensure stable data transmission. Similarly, the serial clock line pin of the first connection subunit 1111 and the series connection of the fourth capacitor can be used for filtering, smoothing signals, suppressing noise, etc.

[0107] The effect of optimizing signal transmission quality is achieved by connecting capacitors in series, which is used to ensure signal stability and reliability.

[0108] like Figure 7 As shown, TYPEC transmits AUX signals through auxiliary signal line 1 (SBU1) and auxiliary signal line 2 (SBU2) without pull-up and pull-down and series capacitors.

[0109] That is, if the signal type of the media resource signal is an interactive signal, and the current interface type corresponding to the media resource signal is a universal serial bus interface (TYPEC), then the serial data line pin (SDA / AUXP / SBU1) of the first connecting subunit 1111 is connected in series with the third capacitor (C471), and the serial clock line pin (SCL / AUXN / SBU2) of the first connecting subunit 1111 is connected in series with the fourth capacitor (C472).

[0110] On the mainboard, the interactive signal is directly connected to the corresponding pin of the receiving channel B port (RXB port) of the video conversion chip (GSV2712) in the mainboard module 120, and the corresponding circuit is selected on the front panel according to the interface type.

[0111] In some embodiments, the signal type in response to the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a high-definition multimedia interface, the first pin of the second connecting subunit 1112 is used to receive a power signal, and the second pin of the second connecting subunit 1112 is used to transmit a request input signal of the media resource signal to the user device.

[0112] In a specific implementation, when the signal type of the media resource signal is a detection signal, during the transmission of the media resource signal, there is also a detection signal used to perform some form of detection or confirmation. This detection signal may be used to check the existence, strength, quality or other relevant parameters of the media resource signal to ensure that the media resource signal can be correctly and effectively transmitted and received.

[0113] If the signal type of the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a high-definition multimedia interface, the first pin of the second connection subunit 1112 is used to receive a power signal. This indicates that the second connection subunit 1112 is not only responsible for signal transmission, but also requires an external power supply to work normally. The provision of a power signal is the basis for ensuring that the connection subunit and the device connected thereto can operate stably.

[0114] The first pin of the second connection subunit 1112 is used to transmit a request input signal of a media resource signal to the user equipment. Through this pin, the second connection subunit 1112 can send a signal to the user equipment to request or instruct the user equipment to start sending the media resource signal. This mechanism may be used to establish or confirm the transmission path of the media resource signal to ensure that data transmission starts at the right time.

[0115] like Figure 8 As shown, HDMI confirms whether there is a signal input by detecting the 5V state output by the user device (SOURCE end), and informs the user device (SOURCE end) that the signal can be output through the second pin (hot plug detection HPD pin).

[0116] That is, if the signal type of the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a high-definition multimedia interface, the first pin (5V / DET / CC2) of the second connecting subunit 1112 is used to receive a power signal, and the second pin (HPD pin) of the second connecting subunit 1112 is used to transmit a request input signal of the media resource signal to the user device.

[0117] In some embodiments, the signal type in response to the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a display interface, the third pin of the second connection subunit 1112 is used to receive a working status signal of a data transmission channel, and the second pin of the second connection subunit 1112 is used to transmit a request input signal of the media resource signal to the user device.

[0118] In a specific implementation, if the signal type of the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a display interface, the third pin of the second connection subunit 1112 receives a working state signal of the data transmission channel, wherein the working state signal of the data transmission channel refers to information about the current state of the data transmission channel, such as whether it is active, data transmission rate, etc. This signal is received through the third pin, and can be used to determine whether there is a signal access.

[0119] The second pin of the second connection subunit 1112 transmits a request input signal of a media resource signal to the user device, which means that this pin is used to send a signal to the user device to request input or start transmission of a media resource signal. This can be a control signal used to start or adjust the playback of a media resource.

[0120] like Figure 8 As shown, DP confirms whether there is a signal access by detecting the AUXN status, and informs the SOURCE end that it can output the signal through the second pin (hot plug detection HPD pin); the HDMI and DP detection signal logic are relatively consistent, connected to the corresponding pin of the RXB port on the motherboard, and different signals can be connected on the front board without the need for additional circuits.

[0121] That is, if the signal type of the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a display interface, the third pin (HPD / CC1) of the second connection subunit 1112 receives the working status signal of the data transmission channel, and the second pin (HPD pin) of the second connection subunit 1112 is used to transmit a request input signal of the media resource signal to the user device.

[0122] In some embodiments, the signal type in response to the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a universal serial bus interface, and the fourth pin and / or fifth pin of the second connecting subunit is connected to the mainboard module 120.

[0123] In a specific implementation, if the signal type of the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a universal serial bus interface, the fourth pin and / or the first pin of the second connecting sub-unit 1112 are used to establish a connection with the mainboard module 120, and signal transmission or device connection is achieved through this connection.

[0124] like Figure 8 As shown, TYPEC detects whether there is a signal input through the CC pin and informs the SOURCE end that the signal can be output. It needs to be connected to the CC pin of the video conversion chip (GSV2712), which is different from the pins connected to HDMI and DP. A switching switch (U44) is used for switching in this application; by controlling the high and low level of the voltage divider signal (TYPEC_SEL signal), it is determined whether it is connected to the 5V / HPD pin or the CC pin of the video conversion chip (GSV2712).

[0125] The switch model is not unique. In addition, if the adapter board has enough interface pins, 5V / DET&HPD and the fourth pin (CC1 pin) / fifth pin (CC2 pin) can be connected separately without switching the switch.

[0126] That is, if the signal type of the media resource signal is a detection signal, and the current interface type corresponding to the media resource signal is a universal serial bus interface, the fourth pin (CC1 pin) and / or the fifth pin (CC2 pin) of the second connecting subunit are connected to the mainboard module 120.

[0127] In some embodiments, Fig. 9 As shown, the video signal compatible circuit 110 includes: an adapter board unit 1101 or an original interface unit 1102;

[0128] The adapter board unit 1101 is configured to receive a media resource signal transmitted by the user equipment in response to the user equipment being connected to the adapter board unit 1101, generate a voltage division signal based on the media resource signal, and transmit the voltage division signal to the main board module 120;

[0129] The original interface unit 1102 is configured to receive a media resource signal transmitted by the user device in response to the user device being connected to the adapter board unit 1101 , generate a voltage division signal based on the media resource signal, and transmit the voltage division signal to the main board module 120 .

[0130] In a specific implementation, when the user equipment is connected to the adapter unit 1101, the adapter unit 1101 is responsible for receiving media resource signals (such as video, audio, etc.) from the user equipment.

[0131] A voltage division signal is generated based on the received media resource signal and then transmitted to the mainboard module 120 for further processing.

[0132] When the user device is not connected to the adapter board unit 1101, in this case, the original interface unit 1102 directly receives the media resource signals from the user device. It also generates divided voltage signals based on these signals and transmits the divided voltage signals to the main board module 120. This shows that the original interface unit has a certain degree of independence and can work without the adapter board unit 1101.

[0133] By including the video signal compatible circuit of the adapter board unit 1101 and / or the original interface unit 1102, the circuit can flexibly adapt to different user devices and signal formats, thereby achieving compatible processing of different user devices and signal formats.

[0134] In some embodiments, Fig.10 As shown, the original interface unit 1102 includes: a first original interface unit 11021 and a second original interface unit 11022;

[0135] The first original interface unit 11021 is configured to, in response to the user equipment not being connected to the adapter board unit 1101, receive the media resource signal transmitted by the user equipment, generate a first type of voltage division signal by using a resistor with a preset second resistance value and a preset second supply voltage, and transmit the voltage division signal to the second original interface unit 11022;

[0136] The second original interface unit 11022 is configured to transmit the divided voltage signal to the mainboard module 120 .

[0137] In a specific implementation, when the user device is not connected to the adapter board unit 1101, the first original interface unit 11021 receives a media resource signal from the user device. A resistor with a preset second resistance value and a preset second supply voltage are used to generate a first type of voltage division signal. The voltage division signal refers to a voltage signal obtained by resistor voltage division, and its type and characteristics depend on the resistance value and supply voltage used. The voltage division signal is transmitted to the second original interface unit 11022.

[0138] The main function of the second original interface unit 11022 is to receive the voltage division signal from the first original interface unit 11021 .

[0139] Regardless of the type of the voltage division signal (i.e., whether it is the first type of voltage division signal generated when the user device is not connected to the adapter board unit, or the second type of voltage division signal generated when the user device is connected to the adapter board unit 1101), the second original interface unit 11022 will further transmit this signal to the main board module 120. The main board module 120 is the core part of the system and is responsible for further processing these signals.

[0140] In summary, the original interface unit 1102 can adjust its signal processing mode according to whether it is connected to the adapter board unit 1101 to adapt to different working environments or requirements, thereby increasing the flexibility and adaptability of the system.

[0141] In some embodiments, Fig.11 As shown, the first original interface unit 11021 includes: a first original interface subunit 110211, a second original interface subunit 110212 and a third original interface subunit 110213;

[0142] The first original interface subunit 110211 is configured to receive a media resource signal transmitted by the user equipment in response to the user equipment not being connected to the adapter unit, and transmit the media resource signal to the second original interface subunit 110212;

[0143] The second original interface subunit 110212 is configured to generate a first type of voltage division signal based on the media resource signal using a resistor with a preset second resistance value and a preset second supply voltage in response to the user equipment not being connected to the adapter unit, and transmit the signal to the third original interface subunit 110213;

[0144] The third original interface sub-unit 110213 is configured to, in response to the user device not being connected to the adapter board unit 1101, control the second original interface sub-unit 110212 to be connected to the third original interface sub-unit 110213, so that the third original interface unit 110213 can receive the first type of voltage division signal generated by the second original interface sub-unit 110212 using a resistor with a preset second resistance value and a preset second power supply voltage; or, in response to the user device being connected to the adapter board unit 1101, control the second original interface sub-unit 110212 to be disconnected from the third original interface sub-unit 110213, generate a second type of voltage division signal using a preset third power supply voltage and a resistor with a preset third resistance value, and transmit the voltage division signal to the mainboard module 120.

[0145] In specific implementation, when the user equipment is not connected to the adapter unit 1101, the first original interface subunit 110211 is responsible for receiving the media resource signal from the user equipment. After receiving the signal, it transmits the media resource signal to the second original interface subunit 110212 for further processing.

[0146] When the user device is not connected to the adapter board unit 1101, the second original interface subunit 110212 processes the received media resource signal. It uses a resistor with a preset second resistance value and a preset second supply voltage to generate a first type of voltage division signal. This voltage division signal is then transmitted to the third original interface subunit 110213.

[0147] The third original interface sub-unit 110213 controls the processing and transmission of signals according to whether the front board is connected to the adapter board unit 1101 .

[0148] When the user equipment is not connected to the adapter board unit 1101 , it controls the second original interface subunit 110212 and the third original interface subunit 110213 to be connected so as to receive the divided voltage signal from the second original interface subunit 110212 .

[0149] When the user equipment is connected to the adapter board unit 1101, it controls the second original interface subunit 110212 to disconnect from the third original interface subunit 110213. At this time, the third original interface subunit uses a preset third supply voltage and a preset third resistance value resistor to generate a second type of voltage division signal, and transmits the signal to the subsequent processing unit.

[0150] In summary, the design of the first original interface unit 11021 allows it to flexibly process media resource signals according to different connection states (whether the adapter board unit is connected). When the adapter board is not connected, it uses a specific set of resistors and supply voltages to generate voltage-divided signals; when the adapter board is connected, another set of parameters is used to generate different types of voltage-divided signals. Such a design is used to ensure signal stability and compatibility to adapt to different working environments and requirements.

[0151] In some embodiments, the serial data line pin of the first original interface subunit 110211 is connected to the serial data line pin of the second original interface subunit 110212, and the serial clock line pin of the first original interface subunit 110211 is connected to the serial clock line pin of the second original interface subunit 110212.

[0152] In specific implementation, the first original interface subunit 110211 and the second original interface subunit 110212 refer to two independent but interconnected front circuit board modules or components. They may be different parts of the same device, or two devices or modules that need to transmit data through serial communication.

[0153] like Fig.12 and Fig.13 As shown, the serial data line pin (SDA / AUXP / SBU1) of the first original interface subunit 110211 is connected to the serial data line pin (SDA / AUXP / SBU1) of the second original interface subunit 110212, and the serial data line pin is used to ensure that data can be transmitted from one front-end board subunit to another via the serial data line.

[0154] The serial clock line pin (SCL / AUXN / SBU2) of the first original interface subunit 110211 is connected to the serial clock line pin (SCL / AUXN / SBU2) of the second original interface subunit 110212. The serial clock line pin ensures that the sender and receiver transmit and receive data bits at the same rate, ensuring that the transmission is synchronized.

[0155] In summary, the serial communication connection between the two front-end board units is established through the serial data line and the serial clock line. This connection allows data to be transmitted synchronously and sequentially between them.

[0156] In some embodiments, in response to the user equipment not being connected to the adapter board unit 1101 , the DC power pin of the second original interface subunit 110212 is connected to the first pin of the third original interface subunit 110213 .

[0157] When implementing it, Fig.13 and Fig.14 As shown, when the user device is not connected to the adapter board unit 1101, the DC power pin (5V_HDMI) of the first original interface sub-unit 110212 is connected to the first pin (5V / DET / CC2) of the third original interface sub-unit 110213, indicating that when the user device is not connected to the adapter board unit 1101, a direct electrical connection is established between the second original interface sub-unit 110212 and the third original interface sub-unit 110213 in the system, and a stable DC power supply is provided to the third original interface sub-unit 110213 through the DC power pin of the second original interface sub-unit 110212 to ensure the normal operation of the display function of the system.

[0158] In some embodiments, Fig.15As shown, the mainboard module 120 includes: a main control chip 121, a video signal type detection circuit 122 and a video signal conversion circuit 123;

[0159] The main control chip 121 is configured to send an interface type detection signal to the video signal type detection circuit 122;

[0160] The video signal type detection circuit 122 is configured to, in response to receiving the interface type detection signal, control the video signal type detection circuit 122 to determine the current interface type corresponding to the media resource signal according to the voltage division signal, and transmit the current interface type to the video signal conversion circuit 123;

[0161] The video signal conversion circuit 123 is configured to obtain the stored historical interface type, determine the target driver based on the historical interface type and the current interface type, and select a target signal processing path from multiple preset signal paths based on the current interface type, and use the target driver to control the target signal processing path to convert the media resource signal to a preset signal type so that the display device can display the media resource signal according to the preset signal type.

[0162] In a specific implementation, the main control chip 121 is configured to send an interface type detection signal to the video signal type detection circuit 122. This signal triggers the video signal type detection circuit 122 to start working to detect the type of interface connected to the media resource signal.

[0163] The video signal type detection circuit 122 is responsible for responding to the interface type detection signal sent by the main control chip 121, and controlling the video signal type detection circuit 123 to determine the current interface type corresponding to the media resource signal according to the voltage division signal.

[0164] Once the current interface type is determined, the video signal type detection circuit 122 transmits this information to the video signal conversion circuit 123.

[0165] The video signal conversion circuit 123 first obtains the stored historical interface type information, which may be used for comparison or reference to determine whether the current driver needs to be updated or maintained.

[0166] Based on the historical interface type and the current interface type, the video signal conversion circuit 123 determines a target driver that is a matching selection for processing the media resource signal of the current interface type.

[0167] Next, the video signal conversion circuit 123 selects a target signal processing path from the preset multiple signal paths. This path is determined according to the current interface type and can match the type to implement the function of processing the media resource signal.

[0168] Finally, the target driver is used to control the target signal processing path to convert the media resource signal into a preset signal type, so that the display device can correctly display the media resource signal of the preset signal type.

[0169] In summary, the mainboard module 121 detects the interface type of the media resource signal, selects a matching driver and signal processing path, and converts the media resource signal into a format understandable by the display device, thereby achieving compatibility and display of different types of media resource signals.

[0170] In some embodiments, Fig.16 As shown, the video signal conversion circuit 123 includes: a storage unit 1231 and a video conversion chip 1232;

[0171] The storage unit 1231 is configured to obtain the stored historical interface type, compare the historical interface type with the current interface type to obtain a comparison result, and in response to the comparison result that the current interface type is the same as the historical interface type, keep the historical driver currently stored in the storage unit, use the historical driver as the target driver, and transmit the target driver and the current interface type to the video conversion chip 1232; or, obtain the stored historical interface type, compare the historical interface type with the current interface type to obtain a comparison result, and in response to the comparison result that the current interface type is not the same as the historical interface type, modify the historical driver currently stored in the storage unit, use the modified historical driver as the target driver, and transmit the target driver and the current interface type to the video conversion chip 1232;

[0172] The video conversion chip 1232 is configured to select a target signal processing path from a plurality of preset signal paths based on the current interface type, and use a target driver to control the target signal processing path to convert the media resource signal to a preset signal type so that the display device can display the media resource signal according to the preset signal type.

[0173] In specific implementation, the video signal conversion circuit 123 is mainly composed of a storage unit 1231 and a video conversion chip 1232. The main function of the conversion circuit is to automatically select or update the corresponding driver according to the interface type of the currently connected display device, and convert the media resource signal into a signal type suitable for the display device through a specific signal processing path.

[0174] The storage unit first obtains the stored historical interface type (ie, the interface type of the display device previously connected), and then compares the historical interface type with the interface type of the currently connected display device.

[0175] If the comparison result shows that the current interface type is the same as the historical interface type, the storage unit 1231 will keep the historical driver currently stored therein as the target driver. This means that there is no need to update the driver because there is already a driver that matches the current interface type.

[0176] If the comparison result shows that the current interface type is different from the historical interface type, the storage unit 1231 will modify the currently stored historical driver to adapt to the new interface type. The modified driver is selected as the target driver.

[0177] Once the target driver and the current interface type are determined, the storage unit 1231 transmits this information to the video conversion chip 1232 .

[0178] The video conversion chip 1232 selects a target signal processing path from a plurality of preset signal paths according to the received current interface type information, and each signal path corresponds to an interface type.

[0179] Using the received target driver, the video conversion chip 1232 controls the target signal processing path to convert the media resource signal (such as a video signal from a computer, a game console, etc.) into a preset signal type that is compatible with the currently connected display device.

[0180] The converted media resource signal is sent to a display device, and the display device displays an image or video according to the preset signal type.

[0181] In summary, the video signal conversion circuit 123 automatically selects or updates the driver and performs signal conversion through a specific signal processing path, thereby ensuring that no matter which type of display device is connected, the display device can achieve normal display function, which improves the compatibility of the system and the convenience of use for users.

[0182] Based on the same inventive concept, Fig.17As shown, an embodiment of the present application proposes a data input control method for a display device, which is applied to a data input control system of a display device in any of the above embodiments, wherein the system includes a mainboard module and a video signal compatible circuit arranged in a front panel, and the method includes:

[0183] Step 1701: receiving a media resource signal transmitted by a user device through the video signal compatible circuit, generating a voltage division signal based on the media resource signal, and transmitting the voltage division signal to the mainboard module.

[0184] Step 1702, using the mainboard module to determine the current interface type corresponding to the media resource signal according to the voltage divider signal, obtaining the stored historical interface type, determining the target driver based on the historical interface type and the current interface type, and selecting a target signal processing path from a plurality of preset signal paths based on the current interface type, using the target driver to control the target signal processing path to convert the media resource signal to a preset signal type, so that the display device can display the media resource signal according to the preset signal type.

[0185] In specific implementation, the data input control system of the display device is mainly composed of two key parts: a mainboard module and a video signal compatible circuit arranged in the front panel.

[0186] The video signal compatible circuit is set in the front panel of the display device. Its main function is to receive media resource signals transmitted from user equipment, which refers to any device that can generate video or audio signals, such as computers, game consoles, digital versatile disc (DVD) players, etc. The media resource signals may include video and audio data.

[0187] The video signal compatibility circuit generates a corresponding voltage-divided signal based on a media resource signal transmitted from a user device of a corresponding interface type, and the voltage-divided signal is then transmitted to the mainboard module for further processing and analysis.

[0188] The mainboard module can determine the current interface type corresponding to the media resource signal based on the voltage division signal. The interface types may include High Definition Multimedia Interface (HDMI), Universal Serial Bus Interface (TYPEC), Video Graphic Array Interface (VGA), Digital Visual Interface (DVI), DisplayPort (DP), etc.

[0189] The motherboard module also stores historical interface type information, which helps the system understand the interface type previously used by the user, and can be used to optimize driver modifications and provide a user-friendly interface switching experience.

[0190] Based on the current interface type and the historical interface type, the mainboard module can determine the target driver. This target driver is necessary to process the current interface type signal to ensure that the signal can be decoded and displayed correctly.

[0191] The mainboard module selects a target signal processing path from a plurality of preset signal paths, which correspond to different interface types or signal processing methods.

[0192] The target signal processing path is driven by the selected target driver to convert the media resource signal into a preset signal type. The preset signal type is a standard signal format that can be recognized and processed by the display device, such as a high-definition multimedia interface.

[0193] Finally, the converted media resource signal is sent to the display unit of the display device for viewing by the user.

[0194] The data input control system of the present application realizes the compatibility, identification, processing and conversion of media resource signals transmitted by user equipment through the coordinated work of the video signal compatibility circuit and the mainboard module, ensuring that the display device can correctly display media resources from different interface types.

[0195] Through the above solution, the interface compatibility of the display device is greatly expanded through the video signal compatible circuit in the front panel. The media resource signal transmitted by the user device can be recognized and processed by the system regardless of its original interface type. The mainboard module intelligently determines the current interface type based on the received voltage division signal, and compares it with the stored historical interface type to select the most appropriate driver and signal processing path. This design not only solves the problem of the single interface of the existing display device, but also provides users with more interface options to meet the diverse connection needs of different users and different devices. In addition, the system can automatically convert the media resource signal to the preset signal type, ensuring that the display device can display content smoothly and with high quality, thereby improving the user experience.

[0196] Based on the same inventive concept, an embodiment of the present application provides a display device, including:

[0197] Display panel;

[0198] The data input control system described in any of the above embodiments is electrically coupled to the display panel and is configured to provide a preset signal type to the display panel so that the display panel displays according to the media resource signal of the preset signal type.

[0199] In specific implementation, the display panel is the core component of the display device, which is used to convert the received signal into a visual image or video. It can be various types of display screens, such as liquid crystal display (LCD), organic light-emitting diode display (OLED), etc.

[0200] The display panel can receive and process signals from a data input control system and display them according to the content of these signals (such as images, videos, text, etc.).

[0201] The data input control system is a system or module electrically coupled to the display panel (i.e., connected by wires or wirelessly). It is configured to provide a media resource signal of a preset signal type to the display panel. The preset signal type refers to one or more signal formats agreed upon between the data input control system and the display panel, which can ensure that the data can be correctly transmitted from the control system to the display panel and correctly parsed and displayed.

[0202] The media resource signal may include various types of content, such as movies, TV programs, pictures, game screens, text information, etc. The data input control system is responsible for converting these contents into a signal format suitable for display on the display panel.

[0203] The working principle of the display device is to use a data input control system to receive media resource signals from external sources (such as TV signal receivers, computers, game consoles, mobile phones, etc.), convert these signals into preset signal types, and then send them to the display panel. The display panel interprets and displays the received signals, and finally presents images or videos visible to the user.

[0204] This design enables the display device to flexibly process various types of media resource signals and ensure that they can be displayed normally on the display panel. At the same time, through the configuration of the data input control system, further control of the display panel can be achieved, such as adjusting parameters such as brightness, contrast, color, etc. to meet the personalized needs of users.

[0205] In some embodiments, the video conversion chip used on the mainboard module of the present application is the GSV2712 of Cornerstone Coollink, which can realize two-in-one video switching conversion. The GSV2712 has two video input signals AB, and the receiving channel A port (RXA port) can access HDMI or DP signals. The receiving channel B port (RXB port) can access any signal of HDMI, DP, and TYPEC, and the output is an HDMI interface. In addition to meeting the basic requirements of the motherboard to expand the video interface, the present application uses the RXB port to realize the data input control process of the display device. Other chips with similar functions can also realize the data input control process of the display device of the present application.

[0206] The architecture of the data input control system of the display device of the present application is as follows Fig.18 As shown, it includes a mainboard module and a video signal compatible circuit arranged in the front panel, the mainboard module includes a video signal type detection circuit, a mainboard (Systemon Chip, SOC) and a video signal conversion circuit, and the video signal conversion circuit includes a video conversion chip and a storage unit (FLASH).

[0207] Among them, the video signal type detection circuit: there is a detection signal (VI_TYPE_DET) on the front board connected to a pull-down resistor with different resistance values, and the pin (VI_TYPE_DET) on the SOC main board is connected to 4.7K and pulled up to 3.3V. After connecting the front board, a voltage divider will be generated on the signal line. The SOC confirms the signal type connected to the adapter board by identifying different voltage dividers; an example is shown in Table 1:

[0208] Table 1

[0209]

[0210] Signal type detection can also distinguish the type of the adapter board video interface through the high and low levels of multiple input / output (IO) ports.

[0211] Video signal conversion circuit:

[0212] The video conversion chip used in this application is GSV2712, whose RXB port can support HDMI / DP / TYPEC input, convert it into HDMI output, and realize different interface input through different firmware, which is stored in the storage unit (SPI FLASH, U30);

[0213] The SOC interacts with the GSV2712 through the synchronous serial bus (Inter-Integrated Circuit, I2C). The SOC can modify the firmware in the SPI FLASH through special instructions.

[0214] The specific working logic is as follows Fig.19 As shown:

[0215] Step 1: After the motherboard is started, the SOC detects the type of the front-panel video interface through the analog-to-digital converter (ADC) in the video signal type detection circuit, and calibrates the interface type HDMI to 1, DP to 2, and TYPEC to 3;

[0216] Step 2: Compare the interface type of the front panel with the one recorded by the system. The initial value of the system record is 0 when the system is started for the first time. If the interface type does not match, rewrite the firmware in the SPI FLASH through I2C, adapt the corresponding video interface, and proceed to the next step. If it matches, proceed to step 4.

[0217] Step 3: According to the front panel signal type, modify the UI interface to the corresponding signal icon and name, and modify the system front panel video interface type record;

[0218] Step 4: Switch the U44 switch according to the video signal type. If it is HDMI or DP, set TYPEC_SEL to 1; if it is TYPEC, set TYPEC_SEL to 0.

[0219] Step 5: When the front panel signal is selected in the user interface, the GSV2712 channel is switched through I2C to display the RXB port video signal.

[0220] Among them, the circuit structure of the receiving channel B port in the video conversion chip is as follows Fig. 20 As shown, the circuit structure of the storage unit is as follows Fig.21 As shown, the circuit structure of the receiving channel A port in the video conversion chip is as follows Fig. 22 shown.

[0221] As an optional embodiment, the video conversion chip used on the mainboard module of this application is GSV2712 of Cornerstone Coollink, which can realize two-in-one video switching conversion. GSV2712 has two video input signals AB, and the receiving channel A port (RXA port) can access HDMI or DP signals. The receiving channel B port (RXB port) can access any signal of HDMI, DP, TYPEC, and the output is an HDMI interface. In addition to meeting the basic requirements of the mainboard to expand the video interface, this application uses RXB port to realize the data input control process of the display device. Other chips with similar functions can also realize the data input control process of the display device of this application.

[0222] The architecture of the data input control system of the display device of the present application is as follows Fig.23As shown, it includes a mainboard module and a video signal compatible circuit arranged in the front panel, the mainboard module includes a video signal type detection circuit, a mainboard (Systemon Chip, SOC) and a video signal conversion circuit, and the video signal conversion circuit includes a video conversion chip and a storage unit (FLASH).

[0223] The video signal type detection circuit and the video signal switching circuit are consistent with the above embodiment, and the difference lies in the video signal compatibility circuit. In addition, the differential data signal and the detection signal processing method among the three types of signals are also consistent with the above embodiment.

[0224] The specific working logic is as follows Fig.24 As shown:

[0225] Step 1: After the motherboard is started, the SOC monitors the voltage-dividing signal (VI_TYPE_DET) level. If the VI_TYPE_DET level is not within the range of the three interfaces, the HDMI interface is used by default. If it is within the voltage range of the three interfaces, the video interface type is confirmed by the ADC value. The interface type is calibrated as 1 for HDMI, 2 for DP, and 3 for TYPEC.

[0226] Step 2: Compare with the interface type recorded by the system. The default interface is HDMI interface. If the interface type does not match, rewrite the firmware in SPI FLASH through I2C to adapt the corresponding video interface and proceed to the next step. If it matches, proceed to step 5.

[0227] Step 3: According to the interface signal type, modify the user interface (UI) to the corresponding signal icon and name, and modify the system video interface type record;

[0228] Step 4: Switch the U45 switch according to the video signal type. If it is HDMI or DP, set TYPEC_SEL to 1; if it is TYPEC, set TYPEC_SEL to 0.

[0229] Step 5: Fig.14 As shown, it is necessary to control whether Q829 is turned on or not according to the video signal type. If it is HDMI, HDMI / DP_SEL is set to 1, Q829 is turned on. If it is DP or TYPEC, HDMI / DP_SEL is set to 0, Q829 is turned off.

[0230] Step 6: When the signal source is selected in the user interface, the GSV2712 channel is switched through I2C to display the RXB port video signal.

[0231] Among them, the circuit structure of U45 switch is as follows Fig.25 shown.
